HOME ABOUT PRODUCTS SUPPORT SALESTouch Screen Selection GuideGeneralA touch screen is an assembly that is mounted in front of a video display. It is activated by touching, with a stylus or finger, the selected area on the display that indicates the desired function. The touch screen or frame has an independent X-Y coordinate system that is calibrated to the display matrix. The X-Y coordinates of the position of the stylus are communicated to the host computer causing the desired action.Other than voice recognition, touch input is probably the most natural human interface to any computing device. It is particularlyuseful and popular in those applications where the user is relatively unskilled in the operation of a computer. For that group ofusers, keyboards tend to be intimidating devices.Touch screens have been used for many years, mainly in applications such as point of sale, public information kiosks, industrialand process control, military displays, medical displays and interactive video systems.Touch Screens for the Factory FloorAs computer based graphic displays and workstations replace switch and indicator banks as the primary man-machine interface for machine and process control, touch screens are becoming increasingly popular as the input device of choice There are several reasons for this increased popularity.q Using touch screens, pop-up alpha and numeric keypads replace fixed, expensive industrial keyboards.q Since video switch banks are software programmable, making changes is significantly less costly than modifying a control panel that contains mechanical switches and indicators.q Using touch input an unskilled user can operate a complex computing device by interacting directly with the video display with relative ease.q Touch targets can be any shape size or color which makes screen design more flexible.q Touch input can provide instant audio and/or visual feedback to tile user to confirm his choice.q Touch active menus can help guide tile user through complex sequences of commands or actions.q Complicated control panels can be simplified by only displaying valid options for any control sequence.This guide is intended to provide a designer with basic tools and selection criteria to allow the most appropriate touch technology and controller configuration to be chosen for their industrial control application.Present Touch Technologiesq Ideally a touch screen would have the following characteristics:q It would not overlay the display and would, therefore, not degrade the display image.q It would have resolution equivalent to that of the video display.q It would be activated by 1) any size stylus 2) conducting or non-conducting styli or 3) a gloved or non-gloved finger.q It would provide a positive, tactile feedback to the operator.q It would be modular and capable of being added to a display and computer in the same manner that other input devices are added.q It would be impervious to dust, grease, moisture chemical or oil vapors or pressure hose down that may be present in a hostile environment.Unfortunately, none of the touch screens currently manufactured have all of those characteristics. Accordingly, the selection of any touch technology is a compromise that will depend on the particular application and environment.There are four major touch technologies--analog resistive, capacitive, scanning infrared (IR) and surface acoustic wave (SAW). All of these technologies provide an assembly consisting of a touch screen overlay or touch frame and a separate controller. The controller is a printed circuit board assembly that must be mounted in either the display device or the computer.Analog ResistiveAnalog resistive screens consist of a sandwich of Mylar and plastic or glass. Usually the Mylar overlay is hard coated to resist abrasion. The two layers are separated from each other by transparent elastic spacer dots. The inside surfaces of the sandwich are coated with a uniform transparent thin film conductive coating, usually indium-tin-oxide (ITO). In operation, a voltage is alternately applied along the horizontal and vertical axes. When the Mylar overlay is depressed and its conductive layer makes contact with the energized layer, that voltage is sensed and transmitted to a controller containing an analog-to-digital converter. The voltage is converted to a digital X or Y touch location. Although the basic analog resistive technology has infinite resolution, the actual system resolution is limited to the resolution of the A-D converter and is generally greater than 1,000x1,000 points.CapacitiveA cross section of a capacitive screen is shown. A glass panel is coated with a conductive coating(usually ITO) that is fused into the glass. The coating is connected to four electrodes at the edges of thescreen. Each electrode is connected to an oscillator circuit. When an operator touches the screen, thebody capacitance of the operator causes a change in the impedance of the screen. The impedancechange causes the oscillator frequencies to vary, and the frequency differentials are converted into X-Ycoordinates by an A-D converter. As with the analog resistive screen, the basic capacitive screen hasinfinite resolution but the system resolution is limited by the signal-to-noise ratio which puts a practicalupper limit on the A-D converter resolution--typically 1,000x 1,000 points.Scanning Infrared (IR)The IR technology is the onlytechnology that does not overlay thedisplay with an additional screen orscreen sandwich. An array of infrared (IR) light emitting diode (LED)/photodetector pairs are mounted in a plastic frame. Using the IR spectrum allowsambient light to be filtered out and makes possible the use of opaque (to thevisible spectrum) plastic frames to hide the photo devices. Thus, the arrayframe simply looks like a bezel. In operation, the LED/photo detector array iscontinuously and sequentially scanned horizontally and then vertically Whenan operator touches the display breaking one or more of the light beams, the X-Y position of the touch stylus is transmitted to the host computer. Themaximum resolution using an interpolation technique is approximately doublethe number of LED/photo detector pairs in the array. Using interpolation, whenan odd number of beams is broken along either axis, the X or Y coordinate ofthe center beam is transmitted, but when an even number of beams is broken,the coordinates of the interpolated beam are calculated and transmitted to thehost computer.Surface Acoustic Wave (SAW)The surface acoustic wave technology is the latest of the touch input technologies and uses inaudible acoustic waves traveling over the surface ofa glass panel at precise speeds in straight lines. X and Y transmittingtransducers are located along the horizontal and vertical edges of a glass plate.Corresponding X and Y receiving transducers are located at the opposite edgesof the glass plate. A reflective array made of powdered glass is printed along theedges of the glass plate. The array consists of .2 mil thick by 1/2 inch widediagonal, parallel lines. In operation, the transducer generates a surfaceacoustic wave which travels along the axis of the reflector array. At eachreflector element, a small amount of the energy in the wave is deflectedorthogonally to the direction of the wave, travels over the surface of the glassand is again deflected orthogonally toward the receiving transducer by a mirrorimage reflector. Since the energy in the wave is reduced as it travels the lengthof the reflective array, the reflector elements are placed increasingly closertogether to compensate for the decreasing energy level. When an operatortouches the screen, a portion of the energy is absorbed by the touch stylus. Thisreduced energy level is detected and, by comparing the speed of the receivedsignal with the known speed of the SAW on glass, an X or Y coordinate locationis registered. As with capacitive screens, the basic SAW technology has infiniteresolution but is limited by the signal-to-noise ratio which puts a practical limit onthe A-D converter--typically 900x900 coordinate locations.Touch Screen ControllersMost manufacturers offer two controller configurations--ISA Bus and Serial-RS232.q ISA bus controllers are contained on a standard printed circuit plug-in board and can only be used on ISA or EISA PCs. Depending on the manufacturer they may be interrupt driven, polled or be configured as another serial port.q Serial controllers are contained on a small printed circuit board and are usually mounted in the video monitor cabinet. They are then cabled to a standard RS232 serial port on the host computer.SoftwareMost touch screen manufacturers offer some level of software support which include mouse emulators, software drivers, screen generators and development tools for Windows, OS/2, Macintosh and DOS.Most of the supervisory control and data acquisition (SCADA) software packages now available contain support for one or more touch technologies.Selection ProcessGenerally there four factors that must must considered for any touch screen application:q The basic touch technologyq The touch controller configurationq The screen surface treatment (not applicable to IR touch screens)q Compatibility with the applications softwareTouch Technology Evaluation Factorsq Resolution-- The smallest detectable increment of stylus movement establishes the touch resolution. Low resolution may be adequate to activate large targets but for mouse tracking or small target activation, resolution equivalent to that of the monitor is desirable.q Parallax-- If a significant variance exists between the target position on the CRT and the point on the touch screen matrix that, when activated by a stylus, causes a touch to be registered the operator could select a different target area than the desired target.q Environment-- The buildup of a layer of dust, oil, grease or any foreign substance on fingers, harsh chemical vapors and hose-down by pressure hoses may cause improper touch operation.q Stylus-- Types of styli typically used with touch screens are bare finger and gloved finger. Occasionally other types of styli including pencil erasers, tips of a pen, may be pointed at the screen and the user expects a responseq Transmissivity-- Overlay touch screens act as a neutral density filter and, therefore attenuate the light from the CRT.q Abrasion-- Touch screen abrasion is experienced in one of three ways. 1) Cleaning of screen with an abrasive 2) Impacting the screen witha sharp object 3) Gradual wearing of the screen from repeated useTouch Technology Selection CriteriaAnalog ResistiveAdvantagesq Highest resolution (better than 1 K x 1 K), smooth mouse tracking and small target activationq Will operate with virtually any stylus including gloved/ungloved fingersq Low parallax with spherical screen that conforms to CRT faceplateq Impervious to dust, oils, grease, moistureq Touch has some tactile feedbackDisadvantagesq Although Mylar overlay has a hard coat and is somewhat abrasion resistant, it can be damaged by gouging from a sharp instrument q Hose down can cause unwanted activation of target areasq Lowest transmissivity of all touch technologies - 55%-65%CapacitiveAdvantagesq High resolution - 1 K x 1 K, smooth mouse tracking and small target activationq Low parallax with spherical screen that conforms to CRT faceplateq Impervious to dust, oils, grease, moistureq Hose-down does not cause unwanted activation of targetsq Impervious to scratching by all but the hardest materialsq High transmissivity - >85%Disadvantagesq Will not respond to gloved finger or any non-conductive stylusScanning Infrared (IR)Advantagesq Best image quality as there is no overlayq Impervious to scratchingq Activates with gloved or ungloved finger and any stylus that is large enough to break IR light beam (typically >.25") Disadvantagesq Low resolutionq Exhibits worst parallax problem of all technologies for CRT use since light beams do not follow curvature of CRT faceplate q May cause unintended activation of target prior to finger contact with CRT caused by IR light beam location above surface of CRT q Pressure hose down may cause unwanted target selectionq Dust, oil or grease buildup on frame that impedes light beam may cause malfunctionSurface Acoustic Wave (SAW)Advantagesq High transmissivity - >92%q High resolution - 900 x 900, smooth mouse tracking and small target activationq Low parallax with spherical screen that conforms to CRT faceplateq Impervious to scratching by all but the hardest materialsq Only technology with Z axis controlDisadvantagesq Pressure hose down may cause unwanted target selectionq Dust, oil or grease on surface of touch screen may cause malfunction or unwanted target selectionTouch Controller Selection CriteriaBus Controllerq Bus controllers are available for ISA/EISA and Micro channel. For any other bus, a serial controller must be usedq Bus controllers usually take a half-length slotq Bus controllers can only be driven a few feet. Therefore the distance between the video monitor and computer must be relatively short q Certain designs are interrupt driven and require the assignment of an IRQ line. Others have a serial port format and require the assignment of a COM port.q Bus controllers are mechanically easier to install.Serial ControllersSerial Controllers are necessary if:q A computer bus other than ISA/EISA or Micro channel is usedq A computer slot is not available but a serial port is availableq There is a separation between the computer and monitor of several feet or moreq No IRQ line is availableSurface Treatment Selection CriteriaTwo types of surface treatment are offered for most overlay screens - clear and anti-glareq Anti-glare screens use an etched surface to diffuse reflected light thus scattering specular reflected light and reducing glare. Unfortunately, this also causes some diffusion of the image. The diffusion is limited if the screen is close to the display surface, but some diffusionremains.q Clear screens have no diffusion of the display image but the screen is highly reflectiveThe choice of clear or anti-glare may be somewhat affected by the intensity and direction of ambient light in the viewing area, but in the final analysis, it is usually a subjective decisionSoftware CompatibilityAfter the touch screen technology and controller have been selected:q It is necessary to determine that the software drivers supplied with the touch screen are compatible with tile latest version of the user's operating systemq If standard application software is being considered. it is necessary to determine that the software is compatible with the drivers and touch hardwareq If software is being developed, it is necessary to ascertain that adequate software drivers and development tools are available SummaryWe have shown that there are many factors to consider in the proper selection of a touch screen, primarily focused on the application and the environment in which it will be used. We have attempted to provide the designer with adequate information to make an informed choice of a touch screen technology that best suits the application.Nortech offers a complete line of touch input workstations, control stations and video monitors. Analog resistive and capacitive touch screens are offered as standard products, since one or the other will best satisfy most industrial control applications for use with CRTs. For generally clean environments, surface acoustic wave (SAW) touch screens may be substituted, if desirable. Nortech does not support scanning infrared (IR) touch screens for use with CRTs.Copyright 1996-2006, Nortech Engineering, Inc., All Rights Reserved。

The object whose temperature is to be measured needs to be larger than the measurement diameter (spot of size) by an adequate margin at least 1.5 to 2 times larger.7. Read the DMM diaplay.MEASUREMENT CONSIDERATIONS1.Theory of MeasurementEvery object emits infrared energy in accordance with its temperature. By mesuring the amount of this radiant energy, it is possible to determine the temperature of the emitting object.2.About InfraredInfrared radiation is a form of light (electromagnectic radiation), and has the property that it, passes easily through air while it is easily absorbed by solid matter. With an emission thermometer which operates by detecting infrared radiation accurate measurement is possible, irrespective of the air tempera-ture or the measrement distance.3.Emission Thermometer StructureInfrared radiation which has been emitted from the object is focused upon an infrared radiation sensor, via an optical system which includes a lens is transparent to infrared rediation, an 5.3µm cut off filter. The output signal from the infrared radiation sensor is input to an electronic circuit along with the output signal from a standard tempeature sensor (Thermopile).4.EmissivityAll objects emit invisible infrared energy. The amount of energy emitted is proportional to the object's temperature and its ability to emit IR energy. This ability, called emissivity, is based upon the material that the object is made of and its surface finish. Emissivity values range from 0.10 for a very reflective object to 1.00 for a black body. Factory set emissivity value of 0.95, which cover 90% of typical applications.5.If the surface to be measured is covered by frost or other material, clean it to expose the surface.6.If the surface to be measured is highly reflective, apply masking tape or matt finish black paint to the surface.7.If the meter seems to be giving incorrect readings check the front cone. There may be condensation or debris obstructing the sensor; clean per instructions in the maintenance section.MAINTENANCEBattery ReplacementPower is supplied by four 1.5V (AAA size) batteries. The "LOW BATT" red LED lighted when replacement is needed.To replace the batteries, remove the screw from the back of the meter and lift off the battery cover case. Remove the batteries from battery contacts.CleaningPeriodically wipe the case with a damp cloth and detergent, do not use abrasives or solvents.Substance Thermal Substance Thermalemissivity emissivity Asphalt0.90 to 0.98Cloth (black)0.98 Concrete0.94Human skin0.98 Cement0.96Lather0.75 to 0.80 Sand0.90Charcoal (powder)0.96Earth0.92 to 0.96Lacquer0.80 to 0.95 Water0.92 to 0.96Lacquer (matt)0.97Ice0.96 to 0.98Rubber (black)0.94Snow0.83Plastic0.85 to 0.95 Glass0.90 to 0.95Timber0.90 Ceramic0.90 to 0.94Paper0.70 to 0.94 Marble0.94chromium oxides0.81 Plaster0.80 to 0.90Copper oxides0.78 Mortar0.89 to 0.91lron oxides0.78 to 0.82 Brick (red)0.93 to 0.96T extiles0.90WARRANTYOMEGA warrants this unit to be free of defects in materials and workmanship and to give satisfactory service for a period of 13 months from date of purchase.

Subsequently, the synthesized two-dimensional MnO2 and Ti3C2 nanosheets with pseudocapacitive properties were electrodeposited onto the interdigitated electrodes to fabricate asymmetric planar supercapacitors with gel electrolyte encapsulated with a transparent polydimethylsiloxane film, where MnO2 was the positive electrode and Ti3C2 was the negative electrode. The results of energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and optical microscopy proved that the microstructures of MnO2 and Ti3C2 after electrophoretic deposition were unchanged and the interdigitated electrodes were prepared successfully, and also showed that the electrophoretically deposited materials were of a thin film structure. The electrochemical performance of the fabricated device was tested by a two-electrode system, which showed that it not only had high rate capability and high energy density, but also maintained high power density and good mechanical flexibility. There was basically no attenuation in capability for the device when being bended at various angles.Keywords:manganese dioxide; titanium carbide; electrophoretic deposition; pseudocapacitance; two-dimensional material; interdigitated electrode; asymmetric planar microsupercapacitor随着现代可穿戴电子设备的持续快速发展，对特征尺寸在微米范围内器件的制备开始成为人们比较感兴趣的问题[1-3]。
临界背光亮度法改善LCD动态调光中的灰度截断
临界背光亮度法改善LCD动态调光中的灰度截断屠震涛;郑仁涛;张小宁【摘要】A critical backlight luminance method to get balance between clipping artifacts and power consumption in local dimming LCDs is proposed. Firstly, the critical backlight luminance of middle backlight blocks and edge backlight blocks are computed with different process. Then the critical luminance is compared with the backlight luminance computed by conventional method, and the larger one is selected as the ideal backlight luminance for superimposing luminance. Finally, the gray-scales after liquid crystal compensation can be obtained according to the superimposed backlight luminance. The experiment results with 81 cm(32 in) LED backlight show that clipping artifacts ratio is reduced effectively and power consumption is not increased obviously.%LED背光源LCD采用动态调光后,为了在灰度截断和功耗之间取得平衡,文章提出了基于临界背光亮度的灰度截断改善方法.该方法首先根据不同的算法分别计算出背光中间模块和边缘模块不产生灰度截断的临界背光亮度,然后将所得到的临界背光亮度与用传统方法得到的对应背光亮度做比较,选择较大值作为最终该模块的理想背光亮度并进行亮度的叠加.液晶补偿的灰度级由叠加后背光亮度得到.81 cm(32in) LED背光源实验结果表明,该方法能够有效地改善灰度截断,同时功耗没有显著增加.【期刊名称】《液晶与显示》【年(卷),期】2012(027)003【总页数】6页(P318-323)【关键词】临界背光亮度;灰度截断;动态调光;LCD【作者】屠震涛;郑仁涛;张小宁【作者单位】西安交通大学电子物理与器件教育部重点实验室,陕西西安710049;西安交通大学电子物理与器件教育部重点实验室,陕西西安710049;西安交通大学电子物理与器件教育部重点实验室,陕西西安710049【正文语种】中文【中图分类】TN873液晶显示器（LCD）由于其重量轻、易于实现高分辨率，以及色彩表现力的不断提升，目前已成为应用范围最广的平板显示器件。

导光板技术之LCD用高亮度导光板
导光板技术之LCD用高亮度导光板前言液晶显示器（LCD:iquid Crystal Display）的背光照明单元（Back Light Unit；以下简称为BLU）是由冷阴极灯管（CCFL:Cold Cathode Fluorescernt Lamp）、CCFL反射膜片（reflectorsheet）、导光板（LGP ight Guide Plate）、LGP反射膜片、扩散（diffuser）膜片等组件所构成（图1）。
为了要提高LGP的光使用效率，通常会在LGP表面设计某些光学机制（device），或者是在LGP内添加材料等两种方法。
背光照明单元使用的光源分别有EL （Electro Luminance）、LED（Light Emitted Diode）、CCFL（Cold Cathode Fluorescernt Lamp）等三种；EL与LED方式主要应用于PDA（Personal Digital Assistant）、行动电话等小型液晶显示器的背光照明单元；CCFL则是应用于NB-PC（Note Book Personal Computer）等大型可携式产品。
如图1所示冷阴极灯管外侧的CCFL反射膜片呈拋物线状（parabolic）将CCFL包围，由光源产生的白光透过该反射膜片反射至由压克力制成的导光板内。
导光板主要功能是藉由光散乱原理将入射的平行光转换成平面垂直光，之后再经过扩散膜片使导光板射出的光线扩散与偏向，最后再经由两片表面成连续锯齿沟槽状的集光棱镜膜片，使光线在xy方向集光并调整光线发散角度。
图1 背光单元的基本结构导光板的种类（a）散乱式印刷导光板如图2所示传统的散乱式导光板底面印刷白色浓淡（gradation）网点使入射光散乱，散乱光的浓淡取决于网点的直径与分布密度。
网点的材质是由UV胶、二氧化钛、硫化钡混合黏稠液所构成。
如图3所示网点直径在灯源入射端为250μm，远离灯源端亦即导光板的端缘的网点直径为1250μm。

单片机红外遥控外文翻译
Infrared Remote And Chips Are IntroducedPeople's eyes can see the visible wavelength from long to short according to the arrangement, in order to red, orange, yellow, green, green, blue, violet. One of the red wavelengths for 0.62 ~ 0.76 mount, Purple is 0.38 wavelength range ~ mount. Purple is shorter than the wavelength of light called ultraviolet ray, red wavelengths of light is longer than that of infrared light. Infrared remote control is to use wavelength for 0.76 ~ 1.5 mount between the near infrared to transfer control signal.Commonly used infrared remote control system of general points transmit and receive two parts. The main component part for the launch of infrared light emitting diode. It is actually a special light emitting diode, due to its internal material differs from ordinary light emitting diode, resulting in its ends on certain voltage, it is a rather infrared light. Use of infrared light emitting diode the infrared wavelengths, for 940nm appearance and ordinary, just the same light emitting diode five different colors. Infrared light emitting diode generally have black and blue, transparent three colors. Judgment of infrared light emitting diode and judgment method, using a millimeter to ordinary diode electric block measure of infrared light emitting diode, reverse resistance. The infrared light emitting diode luminescence efficiency to use special instrument to measure precise, and use only spare conditions to pull away from roughly judgment. Receiving partof infrared receiving tube is a photosensitive diode.In actual application of it receiving diode to reverse bias, it can work normally, i.e., the infrared receiving circuit application in diode is used to reverse, higher sensitivity. Infrared receiving diode usually have two round and rectangular. Due to the power of infrared light emitting diode (or less commonly 100mW), so ir receiving diode received signals is weak, so will increase high-gain ones.the amplifier circuit.In common CX20106A, etc. PC1373H moon infrared receiving special amplifier circuit. In recent years both amateur or formal products, mostly using infrared receiving head finished. The head of infrared receiving product packages generally has two kinds: one kind USES sheet shielding, A kind of plastic packaging. There are three pin, namely the power is (VDD), power negative (GND) and data output (VO or OUT). Infrared receiving head foot arrangement for types varied, manufacturer's instructions. Finished the advantages of infrared receiving head is not in need of sophisticated debugging and shell screen, use rise as a transistor, very convenient. But when used in the infrared receiving attention finished first carrier frequency.Infrared remote common carrier frequency for 38kHz, this is transmitted by using 455kHz Tao Zhen to decide. At the launch of crystals were integer frequency, frequency coefficients, so commonly 12, so 455kHz ÷ 12 hundredth kHz 38kHz hundredth 379,000. Some remote control system adopts 36kHz, 56kHz, etc. general 40kHz launched by the crystals of oscillation frequency to decide.Infrared remote characteristic is not influence the surrounding environment and does not interfere with other electric equipment. Due to its cannot penetrate walls, so the room can use common household appliance of remote control without mutual interference, Circuit testing is simple, as long as given circuit connection, generally does not need any commissioning can work, Decoding easily, can undertake multiple remote control. Because each manufacturer produces a great deal of infrared remote application-specific integrated circuit, when need press diagram so jip. Therefore, the infrared remote now in household appliances, indoor close (less than 10 meters) in the remote control is widely used.Multiple infrared remote control system of infrared emission control buttons, there are many parts general representative of different control function. When pressed a button, correspondingly in the receiver with different output.Receiving the output state can be roughly divided into pulse, level, self-locking and interlock, data five forms. "The pulse output is according to launch" when the button, the receiver output terminals output corresponding "effective", a pulse width 100ms in general. "Level" refers to the output launch press button, the receiver output corresponding output level ", "effective transmit to loosen the receiver" level "disappears. This "effective pulse" and "effective", may be of high level is low, and may also depend on the output corresponding static state, such as feet for low, static "high" for effective, As for the static, "low" high effective. In most cases, "high" for effective. "Since the lock" refersto launch the output of each time you press the button, a receiver output corresponding change, namely originally a state for high level into a low level, originally for low level into high level. The output power switch and mute as control etc. Sometimes also called the output form for "invert". "The interlock" refers to multiple outputs each output, at the same time only one output. The TV sets of this case is selected, the other is like the light and sound input speed, etc."Data" refers to launch the output some key, use a few output form a binary number, to represent different keystroke.Normally, the receiver except a few data output, but also a "valid" output data, so the timely to collect data. This output form with single-chip microcomputer or are commonly used interface. In addition to the above output form outside, still have a "latch" and "temporary" two forms. The so-called "latch" refers to launch the output signal of each hair, the receiver output corresponding ", "new store until you receive signals. "Temporary" output and the introduction of "level" output is similar.Remote distance (Remote Control effect of RF Remote Control distance) are the major factors as follows:unched in power transmission power: while distance, but great power consumption, easy to generate interference.2.and receiving the receiver sensitivity, receiving, remote distance increased sensitivity to improve, but easy to cause disturbance maloperation or abuse.3.antenna, using linear antenna, and parallel, remote distance, but occupies a large space, in use the antenna spin, pull can increase the remote distance.4.and the higher height: antenna, remote farther, but by objective conditions.5.and stop: current use of wireless remote use of UHF band stipulated by the state, the propagation characteristics of approximate linear transmission, light, small, transmitters and receivers diffraction between such as walls are blocking will greatly discounted remote distance, if is reinforced concrete walls, due to the absorption effect conductor, radio waves.Considering the design of hardware volume small to be embedded in the remote control, so we chose 20 foot single-chip chip AT89C2051. Below is the introduction of the function.（1）AT89C2051 internal structure and performanceAT89C2051 is a byte flash 2K with programmable read-only memory can be erased EEPROM (low voltage, high performance of eight CMOS microcomputer. It adopts ATMEL of high-density non-volatile storage technology manufacturing and industrial standard MCS - 51 instruction set and lead. Through the combination of single chip in general CPL1 and flash memory, is a strong ATMEL AT89C2051 microcomputer, its application in many embedded control provides a highly flexible and low cost solutions. The compatible with 8051 AT89C2051 is CHMOS micro controller, the Flash memory capacity for 2KB. And CHMOS 80C51 process, have two kinds of leisure and power saving operation mode. The performance is as follows.5.CUP, 2KB Flash memory,Working voltage range 2.7-6V, 128KB data storage.The static working way: 0-24MHz, 15 root input/output line.A programmable serial, 2 a 16-bit timing/counters.Thereis a slice of inside precision simulation comparator, 5 the interrupt sources, 2 priority.Programmable serial UART channel, Directly LED driver output,The internal structure of AT89C2051 is shown in figure 1.Figure 1 AT89C2051 interior structure（2）AT89C2051 chip pin and functionIn order to adapt to the requirement of intelligent instrument, embedded in the chip foot AT89C2051 simplified configuration, as shown in figure b. The major changes to: (1) the lead foot from 20 to 40 wires, (2) increased a simulated comparator.=Diagram b AT89C2051 foot figure.AT89C2051 pin function:1.the VCC: voltage.2. to GND.3.P1 mouth: P1 mouth is an 8-bit two-way I/O port. P1.2 ~ P1.7 mouth pin the internal resistance provides. P1.0 and P1.1 requirements on the external pull-up resistors. P1.0 and P1.1 also separately as piece inside precision simulation comparator with input (AIN0) and reversed-phase input (AIN1). Output buffer can absorb the P1 mouth 20mA current and can directly LED display driver. When P1 mouth pin into a "1", can make its input. When the pin P1.2 ~ P1.7 as input and external down, they will be for the internal resistance and flow current (IIL). In flash P1 mouth during the procedure and program code data receiving calibration.4.P3: the P3.0 ~ P3.5 P3, P3.7 is the internal resistance with seven two-way I / 0 lead. P3.6 for fixed inputs piece inside the comparator output signal and it as a general I/Ofoot and inaccessible. P3 mouth buffer can absorb 20mA current. When P3 mouth pin into "1", they are the internal resistance can push and input. As input, and the low external P3 mouth pin pull-up resistors and will use current (IIL) outflow. P3 mouth still used to implement the various functions, such as AT89C2051 shown in table P3 mouth still receive some for flash memory programming and calibration of program control signals.5.RST: reset input. RST once, all into high level I/O foot will reset to "1". When the oscillator is running, continuous gives RST pin two machine cycle of high level can finish reset. Each machine cycle to 12 oscillator or clock cycle.6.XTAL1: as the oscillator amplifier input and inverse internal clock generator input.7.XTAL2: as the oscillator reversed-phase the amplifier's output.P3 mouth function as is shown in table 1.（3）the software and hardware constraints. AT89C2051Due to the foot of the chip AT89C2051, no set limits of external storage interface, so, for external memory read/write instructions as MOVX etc.Due to 2KB ROM, so, the space to jump instruction should pay attention to the destination address range (transfer 000H - 7FFH), beyond the range of addresses, will not meet wrong results. The scope of data storage is 00H (7FH -- when stack manipulation), also should be noticed.The input signal is simulated by the original P3.6 foot into the microcontroller, so the original P3.6 foot.Unable to external use. Simulation comparator can compare two simulation, if the size of the voltage external A D/A converter and its output as A comparator analog input, and by simulating the comparator another input voltage to be measured, through the introduction of the software method can realize the A/D conversion.8.the Flash memory AT89C2051)Provide a 2KB of single-chip AT89C2051 in Flash memory chips, which allows the online program to modify or use special programming programming.(1)Flash memory encryptionAT89C2051 SCM has 2 encryption, can programming (P) or programming (U) to obtain different encryption functionality.

Abstract—In this paper, we propose a novel mobile LCD device for simultaneous touch and hover sensing. A transparent infrared image sensor panel allows the device to display contents and to detect touch and hover actions alternately. The proposed system has an advantage over touch screen devices in that a user interacts with a mobile device by not only touching the display screen but also hovering over the display screen.I.INTRODUCTIONTouch screen device market is rapidly growing since it provides an intuitive way to interact with display devices. Touch screen device can accurately map positions of user’s fingers on the display screen onto input commands which allow various tasks to be performed through different commands based on touch actions. However, since mobile devices have a small screen size such as 3.5" and 4.3", touching the screen with fingers sometimes occludes displayed contents. Moreover, touch-only devices limit user interaction to a 2-dimensional plane on the display screen. Thus, adding the capability of sensing hover actions in a touch display provides more natural interaction means for mobile devices. Previously, an optical sensing system using retro-reflective opto-sensors integrated with an infrared (IR) emitter and an IR detector which is placed behind an LCD panel was proposed to detect touch and hover points [1]. However the architecture in [1] has several problems in that display image quality is degraded and sensors behind the LCD panel might be visible due to the removed diffuser plate. Another approach to simultaneously detect touch and hover is to integrate photo-sensor circuit into a TFT-LCD during manufacturing process [2]. But this requires changing an LCD manufacturing process to insert photo sensors in cell.In this paper, we present a mobile LCD device for concurrent detection of touch and hover actions. A key element of the proposed architecture is a transparent IR image sensor panel which sense fingers placed on or near the display surface while uniformly distributing light from a backlight to the LCD screen. Since it is fabricated with amorphous silicon (a-Si), we can use an a-Si TFT LCD process which is common to TFT LCD fabrication.II.T HE P ROPOSED S YSTEMA.Display Architecture for Touch and Hover SensingWe propose a mobile LCD device to sense touch and hover simultaneously. Compared to a conventional LCD display, the proposed architecture includes additional two layers of a front illumination unit and an IR image sensor panel. Figure 1 illustrates an optical structure of our proposed architecture to concurrently detect touch and hover. It is composed of (1) a front illumination unit to beam IR light toward objects on and above the display surface, (2) an LCD panel, (3) prisms and light enhancement films, (4) a transparent IR image sensor panel to sense the reflected IR light from objects, (5) a diffuser film, and (6) a backlight unit. The front illumination unit radiates IR light to an IR light guide for touch detection based on frustrated total internal reflection [3] and beams IR light toward near object for hover detection in the same time. Then the reflected IR light is captured in the transparent IR sensor panel.Fig. 1 Optical structure of the proposed mobile LCD device fortouch and hover detectionB.Front Illumination UnitThe front illumination unit causes near object to cast reflected IR light for hover illumination while trapping IR light in the light guide plate for touch illumination. As shown in Fig. 2, the front illumination unit includes an obliquely cut edges of an acrylic light guide plate. IR light beamed at two obliquely cut edges travels to the inside of the plate for touch while heading toward the outside of the plate for hover.Fig. 2 The front illumination unit for simultaneous touch andhover illuminationMobile LCD Device with Transparent Infrared Image Sensor Panel for Touch and Hover SensingSungjoo Suh, Kwonju Yi, Changkyu Choi, Dusik Park and Changyeong Kim Advanced Media Lab., Samsung Advanced Institute of Technology, Samsung Electronics, Korea2012 IEEE International Conference on Consumer Electronics (ICCE)1569490199 978-1-4577-0231-0/12/$26.00©2012 IEEE217C. Transparent IR Image Sensor PanelSince a traditional image sensor panel is opaque, using the traditional sensor panel to sense touch and hover prevents a backlight from distributing visible light on a surface of an LCD panel for displaying contents. Instead of that, we propose a transparent IR image sensor panel which includes optically transparent pixels. The transparent pixels and the sensor pixels are interleavingly located in the sensor panel so that light from a backlight can be uniformly transmitted to the LCD screen. Figure 3 represents a microscopy image of the transparent IR image sensor panel we have fabricated. It has a photoconductor of a finger structure with 100×100µm 2 active area out of a 153×153µm 2 physical sensor area and has a transparent pixel with 153×153µm 2. The transparent IR sensor panel is fabricated with a-Si in that we can use an a-Si TFT LCD process which is common to TFT LCD fabrication as shown in Fig. 4. Since the size of the sensor panel is 3.5", a spatial resolution of the sensor panel is 480×320 pixels including transparent pixels. In order to secure enough sensitivity to near IR light around 850nm, thickness of the a-Si:H layer was chosen to 5000Å.Fig. 3 Microscopy image of the transparent IR sensor panelFig. 4 Cross sectional view of the photoconductor(a) Mobile LCD prototype (b) Transparent IR sensor panel Fig. 5 Microscopy image of the transparent IR sensor panel(a) Touch image (b) Hover image Fig. 6 Calibrated sensor image for touch and hoverIII. E XPERIMENTAL R ESULTSWe built a 3.5" mobile LCD prototype with the front illumination unit and the transparent IR image sensor panel for touch and hover detection as shown in Fig. 5(a). The fabricated transparent IR image sensor panel inside of the prototype is shown in Fig. 5(b). The sensor panel is transparent so that we can see a paper behind the sensor panel. Figure 6 represents calibrated sensor images from the prototype. When a finger touches the surface of the LCD panel, the touch region is clearly sensed as shown in Fig. 6(a). When a finger hovers over the display screen at 20mm, the hover region is captured as depicted in Fig. 6(b). The hover image is slightly blurred compared to the touch image.IV. C ONCLUSIONWe have presented a mobile LCD device for touch and hover sensing. By employing a transparent IR image sensor panel and a front illumination unit, it is possible to detect both touch and hover events. Due to the transparency of the proposed sensor panel, display image quality of the device is maintained since light from a backlight is uniformly distributed to the LCD panel. We believe that our proposed system can provide more natural interaction means which touch-only devices cannot offer.R EFERENCES[1] Shahram Izadi, Steve Hodges, Alex Butler, Alban Rrustemi and BillBuxton, “ThinSight: versatile multi-touch sensing for thin form-factor displays,” in Proceedings of the 20th annual ACM symposium on User Interface Software and Technology , New York, pp. 529-551, 2007.[2] Kohei Tanaka, Hiromi Kato, Yasuhiro Sugita, Naru Usukura, andKazuhiro Maeda, “The technologies of in-cell optical touch panel with novel input functions,” Journal of the Society for Information Display , vol. 19, no. 1, pp. 70-78, 2011.[3] J.
