IC讯号输入方式
Cut Corner
TFT元件除本身漏电问题外，因实际工作時B/L所造成的光漏电对Flicker也有很大的影响。
1）以8SD为例，BL照度越大，Ioff变化较大； Ioff变大，device在holding状态下的压降越大，从而闪烁越严重。 2）通过量測不同BL强度下的Vth bias量可以初步评价Ioff对Flicker的影响。

DSP-based 1 M sample per second, no-gap/no overlap 200 mS data acquisition and powerful FFT analysis ensures full compliance harmonics testing based on IEC 61000-4-7. Direct PC bus access ensures higher data throughput than is found on most single box IEEE-488-based test system. Streaming real-time data display and storage allows measured data to be replayed and analyzed in complete confidence, speeding up fault detection.All EUT electrical parameters are monitored and stored continuously. Distortion, current har-monics and power consumption are checked against relevant IEC class test limits for pass/fail detection and dynamic class C and D test limit calculation.Independent verification has confirmed the following is correctly implemented: Measurement accuracy for electrical parameters such as voltage, current, harmonics and flickermeter is as per IEC requirementSoftware applies relaxation as and when the situation warrants it for pass/fail decision Compliance to all test equipment requirements as per IEC 61000-4-7 and IEC 61000-4-15A true measure of class. The unique concept for the ProfLine 2100 system measurement section is a cutting edge PC based analyzer. The measurement section is split into two parts, one being the advanced coupling unit CCN 1000 whilst the PC provides the digitization of the analogue signals, data processing and analysis. This approach has been extremely successful in keeping up with changes to the standards that demanded major increase in data processing and analysis capability.CCn 1000. This advanced coupling unit provides quick and easy single cable connection between the AC power source output and the EUT, plus the required isolation and signal con-ditioning. Precision, no-burden, active hall-effect current transformers ensure accurate current sensing over 4 A, 16 A and 40 A ranges simultaneously with 200 A peak capability for maximum resolution.6data Acquisition Unit Input ChannelsAll harmonics tests can be accessed from the ProfLine 2100’s single control and data display window on the PC. With a few mouse clicks the test can be set up and run quickly and easily.The operator is presented with a simple screen that shows the type of test to be run and the test duration, with clearly labelled buttons for the test to start or stop. Voltage and current time domain waveform displays are updated in real time during the test. All power analyzer parameters such as Vrms, Irms, Ifundemental, Ipeak, crest factor, real power, apparent power and power factor are clearly displayed throughout the test and updated in real time.The harmonics window displays instantaneous current harmonics and a line marking the appli-cable test limits. AC source voltage and EUT power are also monitored continuously throughout the entire test. Voltage distortion and current harmonics are checked against the IEC class limits for preliminary pass/fail detection. The continuous monitoring of EUT power consumption allows class C and D limits to be calculated dynamically.Harmonics analysis is implemented using the high performance DSP based plug-in A/D card connected directly to the CCN 1000 signal conditioning unit through a shielded cable. Each Power phase has four dedicated measurement channels- a total of 12 in 3-phase systems – ensuring accurate full compliance to the harmonics standard.The software will also automatically apply any relaxation of limits (e.g. POHC) should the situation warrant it and will indicate this in the test report.78All IEC harmonics tests can be accessed from ProfLine 2100’s single control and data display window on the PC.

Set up is minimal and tests run can be started quickly.during each test run two graphical windows are displayed and updated continuously. One window will display the Vrms whilst the other can be user selected to display absolute voltage deviation or percentage, dt, dmax, dc, instantaneous Pst or Plt against their respective limits. At the end of the test sequence, both short-term flicker (Pst) and long-term (Plt) are calculated and a clear pass/fail indication is provided.Embedded in the ProfLine 2100 software is an IEC 61000-4-15 compliant single/three-channel flickermeter for 1- and 3-phase application. Single phase output configuration can use both the programmable and real IEC 60725-compliant output impedance to perform flicker measurement.

For single phase systems the impedance is programmed into the source, therefore no physical impedance is required thus making the system more simple and lower costs. This approach is not possible in the three phase systems as it is not possible to separate the line and neutral impedances. Therefore the appropriate three phase impedance unit is supplied as part of the system.Test reports and data Logging. Reports can be printed at the end of each test report or retrospectively to support CE approval or for inclusion in a Technical Report File. The results file includes voltage and current waveform graphs, current harmonics spectrum and class limits and a complete flicker test analysis. The graph can be printed or stored in ASCII format on disc along with timing waveform data for use in detailed reporting or for further analysis using applications such as Excel.1112nSG 2200 AC Switch unit for complaint -4-11 and -4-34 testing. Available as either singleor three phase, these units use solid state IGBTs to rapidly switch between two sources of ACsupply. Typically this will be between the mains supply and a programmable AC source. TheAC source will be set at the lower voltage required for the test with the mains supplying thehigher.Controlled by Teseq WIN 2120 software and able to switch within the required 5 μs this deviceenables the standard to be fully met. Since the higher voltage level is supplied by the usersmains system, the inrush current is limited only by the mains supply and not by the equipment.The NSG 2200 is able to handle 50 amps rms current continuously and up to 500 amps inrush current.AC fast switching unit for standards specifiedin the IEC 61000-4-11Unit has two inputs, AC source and AC MainsAllows for single- or three-phase mode testingAC SwitchAC SwITChING UNIT13Magnetic field immunity testing. The power sources in the ProfLine 2100 systems makean ideal source for mains frequency magnetic field testing. Used in conjunction with the TeseqINA 2170 test coil and interface unit the supplies can be controlled by the WIN 2120 software togenerate the required fields and frequencies.Use of the clean sinusoidal programmable supply ensures that tests can be performed witheither 50 Hz or 60 Hz for different regions. Both the continuous and short duration tests can beeasily programmed at levels up to 100 A/m continuous and 300 A/m short duration dependingon the selection of source.Magnetic coilsIEC 61000-4-8 power frequency fieldAutomated test softwareAdjustable single loop antenna in 3 positionsNote: maximum and continuous coil field strengths can only be achieved using the correctlyspecified NSG 1007 AC/DC Power Source. INA 2170 coils can also be used for IEC 61000-4-9testing in conjunction with Teseq’s nSG 3060 generators.MAGNETIC fIELDIMMUNITY TEST COILSPROfLINE 2100: MORE ThANjUST hARMONICS & fLICkERProfLine 2100 has the hardware and software flexibility to test to beyond harmon-ics and flicker emission. The fully programmable AC power source with arbitrary waveform generation capability can be used in standalone mode in various applications for IEC 61000-4-X testing at pre or full-compliance. The ProfLine system has built in IEC 61000-4-13 immunity testing to harmonics and inter-harmonics standard which sets this system apart as a fully equipped test station for power quality.IEC 61000-4-8: Power frequency magnetic field immunity. Using the power source built into the ProfLine 2100 system the frequency and test level can be accurately controlled. This is ideal if your target market uses a different mains system to your local supply.Loop antenna, interface unit and control software (WIN 2120) are available as options.IEC 61000-4-11: AC Voltage dips, short interruptions and variations. The 1–5 µs rise and fall time and the 500 amp inrush current requirements of the standard for voltage dips and interruptions mean that a power source alone cannot meet the standard.The NSG 2200 AC switch can switch between a power source and the mains supply within the required time enabling the user to meet both requirements.IEC 61000-4-13: Immunity to harmonics and inter-harmonics. ProfLine 2100’s built in sweep generator provides full compliance testing to IEC 61000-4-13. Simple pre-programmed test levels at various test classes makes testing simple. At a click of the start button the two digitally controlled generators superimpose harmonics and inter-harmonics up to the 40th harmonics order (2 kHz for 50 Hz and 2.4 kHz for 60 Hz). The programmable AC power source generates combination waveforms better known as the flat top, overswing and meister curve, tests individual harmonics, and does a sweep to check for resonance points. The user can then go back to those resonance frequencies and test again. The operator can record any unusual behaviour at the observation section which will be included in the report. Pass/fail decision will be determined by the user based on the evaluation of the EUT during the test.1415IEC 61000-4-14: Voltage Fluctuation. A simple screen allows the operator to select the levelof severity of test to be run and the desired nominal test voltage and frequency. All voltagefluctuation test parameters can be customized by the user as required, ensuring the ProfLine2100 fully meets the standard. During testing, the EUT load current is measured continuously tohelp the operator observe and diagnose potential unit failures.IEC 61000-4-17: Ripple on DC input power ports. The test sequence implemented by thistest consists of the application of an AC ripple of specified peak to peak value as a percentageof the DC voltage and at a frequency determined as a multiple of the AC Line frequency. Theripple waveform consists of a sinusoidal linear waveshape. The user selectable severity levelscan easily meet the multiple of the power frequency of 1, 2, 3, 6 and at the user specified levelup to a staggering 20 times the power frequency at 25% Vdc-peak-peak.IEC 61000-4-27: Voltage and phase unbalance. This test is only for three-phase systemsas it involves voltage and phase unbalance between phases of a three phase supply network.Voltage unbalances are applied at different levels depending on product categories. The usermust determine the product class and select the appropriate test level. During the test run,voltage and phase changes are applied. The voltage levels and phase shifts are determined bythe values set in the data entry grid. Predefined test level are also provided to help the operatorwith the settings.Note: The ProfLine 2100 does not fully meet the IEC 61000-4-27 in respect of this particular test,1–5 µs rise fall rate not achievable and maximum output voltage is 300 V. So whilst it can meetthe 110% of U nom required by the product standards (110% of 230 V is 253 V) it does not reachthe 150% of U nom mentioned in the equipment standard (150% of 230 V is 345 V). 45 kVA unitshave a 400 Volt option.16IEC 61000-4-28: Frequency variation. The system provides an open field for the operator toenter the amount of frequency variation or simply load and amend the predefined tests levelprovided. Test parameters for the duration and frequency deviation can be easily customized,enabling ProfLine 2100 to meet this standard should there be changes to it in the future.IEC 61000-4-29: dC dips, variations and short interruptions. Pre-compliance test for DCvoltage dips can be set up quickly using the software. The test sequence implemented by this testconsists of a series of DC voltage dips (to less than DC nominal) or interruptions (dip to 0 V). It isalso possible to select voltage variations which cause the DC voltage to change at a programmedrate to a specified level and then return at the same or a different rate to the nominal DC level.These dips and variations can be applied at different levels and durations for different productcategories. The user must determine the product class and select the appropriate test file. Theselected levels and durations are visible on screen and can be edited and saved to a new setup fileif needed. This allows a library of test files for specific product categories to be created. Accordingto the standard, the use of a test generator with higher or lower voltage or current capability isallowed provided that the other specifications are preserved. The test generator steady statepower/current capability shall be at least 20% greater than the EUT power/current ratings.This means that for many EUT’s a 25 A capable generator is not needed. However, since the riseand fall time requirements may not be met under all circumstances, this is a pre-compliancetest only.IEC 61000-4-34: AC Voltage dips, short interruptions and variations. Similar to IEC61000-4-11 but applying to equipment requiring greater than 16 amps per phase, this standardcan be met by the higher power models in the range.

IEC Flicker Impedance M6204 电源闪烁阻抗器M6204说明书
The M6204 unit provides the requisite lumped impedance between the AC Power Source and the Unit Under Test (UUT) used to test for flicker compliance to IEC 61000-3-3. Designed to meet IEC 60725 - Consideration of reference impedances and public supply network impedances for use in determining the disturbance characteristics of electrical equipment having a rated current ≤75 A per phase – the M6204 simulates the typical public utility impedance characteristics found in most European countries in order to provide a common flicker measurement reference.IEC Flicker ImpedanceStandard Features:•Three Phase Flicker Impedance Network Supports both single and three phase flicker testing of UUT’s up to 16Arms per phase•Z ref Impedances Values per IEC 60725Line Impedance: 0.24 Ω+ 0.15 j Ω Neutral Impedance: 0.16 Ω + 0.10j Ω•Compatible with 360AMXT and 3120AMXT AC Source ModelsIEC Impedance is matched to AC Source Output impedance for exact IEC 60725 matching•High Qualify Impedance Components Used Low Thermal Drift and Forced Air Cooling while under Load Ensures Constant Flicker Impedance during Long Flicker Test Runs •Dual Connectors on Rear PanelMultiple Terminal Blocks Provided for Power, Voltage Sense and Power Analyzer Connections Simplifies Connections •Standard 19” Rack Mount EnclosureFits easily on Lab Bench, on top of the AC Power Source used or in an Instrument CabinetStandards Supported:• IEC 61000-3-3 / EN 61000-3-3• IEC 61000-4-13 / EN 61000-4-13• IEC 61000-4-27/ EN 61000-4-27•IEC 60725The Leader in AC Power TechnologyFREQUENCY CONVERSION R & D MANUFACTURING AEROSPACE MILITARY CUSTOMA separate impedance network in the Neutral leg ensures full compliance to IEC 61000-3-3 and IEC 60725 even under imbalanced three phase load conditions. The same three phase Impedance network is also fully capable of supporting single phase Flicker test. In this case, the Phase A impedance and Neutral impedance combine together to provide the required Z ref = 0.40 Ω + 0.25 j Ω single phase impedance.Three Phase and Single Phase UUT TestingThe use of high quality components with low thermal drift and high saturation resistance ensures a stable impedance network throughout the entire flicker test duration – typically two hours. This is augmented by efficient yet quiet forced air cooling. Testing to the full 16 Arms per phase as required for products that fall under the IEC 61000-3-3 Flicker Standard is fully supported by this lumped impedance with ample margin for temporary overload conditions.Full 16 Arms per Phase CapableAC Source MatchedAn early pioneer in the development solid-state power conversion equipment, Pacific Power Source continues to develop, manufacture, and market both linear and high-performance PWM AC Power Sources. Pacific’s reputation as a market and technology leader is best demonstrated by its continuing investments in both research and development and world-wide customer support. With corpo-rate owned offices in the United States, Germany, the United Kingdom, and China, local personalized support is always available.12KVA Three Phase 16 Arms/Phase IEC 60725 CompliantThe M6204 impedance is factory calibrated and matched to the AMX AC Power Source Model it is used with. This ensures that the combination of AC Source Output Impedance and Lumped Impedance adds up to the requisite IEC 60725 Impedance values. This prevents unwanted system level errors that can occur when the IEC Flicker Impedance is sourced from a different vendor as the AC Power Source.ApplicationsThe M6204 IEC Flicker Impedance provides the required lumped impedance to create a Flicker test system consisting of a Programmable AC Power Source, an IEC compliant Flicker Meter or Power Analyzer with Flicker measurement mode and the required lumped impedance between the AC Source and the UUT. The IEC Flicker standard is based on analyzing voltage fluctuations caused by changes in UUT load current working against a reference impedance (Z ref ). Z ref was cho-sen to simulate the typical public utility impedance found in Europe. An incorrect or out of tolerance Flicker Impedance can lead to significant errors in Flicker measurement results.Flicker TestingFor single phase applications, the Phase A and Neutral impedance combine to provide the required single phase Z ref of Z = 0.40 + j0.25 Ω so the same M6204 Impedance can be used for either single or three phase Flicker testing.Phase Impedances: Z L = 0.24 + j0.15 Ω each phase Neutral Impedance:Z N = 0.16 + j0.10 ΩOther IEC Test StandardsThe same IEC Flicker impedance is also called out to be used during other IEC Tests. Examples of some of these IEC Test Standards are shown in the table below.The M6204 Impedance is compatible with these IEC 61000-4 Immunity test standards.High QualityBenefits•The M6204 IEC Flicker Impedance is constructed of high quality resistive and inductive components sized to handle load currents up to 16Arms with ease. Proper heat sinking and forced airflow ensure stable operation over a wide temperature range, even under full load conditions that can persist for many hours. The same impedance module can be used for either Single phase or Three phase UUT Flicker testing without the need to rewire or re-configure.Lumped Impedance•Compared to “synthesized or electronic” impedance solutions as employed by some manufacturers, the M6204 pro-vides the required separate Neutral Impedance which is not available on AC Sources with synthesized impedance. This ensures accurate Flicker measurement results under all circumstances, including unbalanced three phase load conditions caused by the UUT.•Furthermore, synthesized impedance circuits often have a limited frequency range and may closely approximate the required impedance at 50Hz but will not accurately simulate the effect of higher current harmonic frequency components present in UUT current for non-linear loads. A lumped impedance like the M6204 does not have such a frequency dependency and will correctly respond to current harmonics.AC Source Matching•Since most AC Power Sources have a non-zero output impedance, adding the lumped impedance to an AC Source will have a cumulative effect resulting in an overall combined output impedance to the UUT that will exceed the ac-tual Z ref value. This will result in overstated Flicker measurement results that may lead to an UUT not passing Flicker test where it otherwise would have.•By obtaining both the AC Power Source and the IEC Flicker Impedance from the same manufacturer, you can be sure both are matched. This means the lumped impedance as well as the AC Source output impedance is adjusted to ensure the combined impedance is within Z ref tolerances.Requirements for the IEC Flicker Impedance when testing UUT’s with Currents up to 75 Arms per phase are covered by IEC Standard 60725, currently at revision 3.0. For UUT’s with phase currents of 16 Arms per phase or less (either single or three phase UUT’s), the required Z ref is defined as a combination of resistive and inductive components with the fol-lowing nominal values:RatingsInput Power Requirments1 If a NON Pacific Power Source AC Power Source model is used with the M6204, an external 24Vdc supply capable of supplying 280 mAdc @ 24Vdc is required to oper-ate the Fan.© 2013 Pacific Power Source, Inc.

It was a Saturday afternoon. The color of the sky was changing, first light gray, then dark gray, and finally dark and dense. The wind was blowing heavily, and the trees were swaying in the strong wind. It began to rain cats and dogs. Soon, the road was filled with puddles from the rain.On such a stormy afternoon, my mother took my five-year-old brother, Christopher, and me to a new big toy store she had read about in the newspaper. “So many toys,” the advertisement had shouted in full and f lashy color, “that we had to get a huge warehouse to fit them all!”Christopher and I couldn’t have been more excited. We ran across the parking lot, through the cold and biting rain, as fast as our little legs could carry us. We left our mother outside to battle with the frustrating umbrella, which never worked when she wanted it to. “Christine! Take care of your young brother!” Mother shouted at the top of her voice.“Christine!I’m going to find the Lego section(乐高积木区)! There’s a new pirate ship I want, and I have four dollars! Maybe I can buy it!” Christopher exclaimed and ran off excitedly. I only half heard him.I took a right turn and, to my wide-eyed delight, found myself in the midst of the Barbie (芭比) World.I was studying a Barbie and doing some simple math in my head when suddenly an earthshaking clap of thunder roared from the storm outside. I jumped at the noise, dropping the doll to the floor. The lights flickered (闪烁) once and died, covering everything in a blanket of blackness. Thunder continued to shake the sky and lightning illuminated the store for seconds, casting frightening shadows on my mind.注意：1.所续写短文的词数应为150 左右；2.续写部分分为两段，每段的开头语已为你写好。

The cells renew themselves by self-division. There are about 25,000,000 cells dividing in adult human body per second. And the dividing speed of the blood cells is about 100,000,000/s. During the process of dividing and growth, the nucleus and the extranuclear electron, the basic components of the cell withelectricity, are making the high- speed movement and changing. In the meanwhile, the electromagnetic waves are radiating outward constantly. The electromagnetic waves stand for the different specific states of human body, such as healthy state, sub-healthy state and disease state. In different states, the corresponding electromagnetic waves are different. Thus, we can check out the human body state if these specific electromagnetic waves are detected.In quantum medical area, the fundamental reason for people suffering disease is that the spinning and the orbiting of the electron have changed, which makes the atoms change, which causes the biological micromolecule change. Therefore, the biological macromolecule changes, gradually, the whole cell starts to change, and ultimately the whole organ change. Since the electron is a charged body, when the spinning and the orbiting of it have changed, the electromagnetic waves inside will change accordingly. The energy of electromagnetic wave variation, which is caused by the different states of dieses and nutrition, is very weak, usually only Ns Gaussian or To Micro-Gauss. The frequency and theenergy of the magnetic field are measured by holding the sensor with hand. It is similar to the theory of listening to the radio. There are various wireless waves in the air, but if you want to listen to certain broadcasting station, you should modulate the radio to the same frequency, which causes the resonance, and then, the radio can get the specific radio station. Quantum Resonance is based on thistheory as well.What is Quantum Resonant Magnetic Analyzer?The Quantum Resonant Magnetic Analyzer is a Hi-tech innovation project, which is related to medical, bioinformatics, electronic engineering, etc. It is based on quantum medical, and scientifically analyzes the human cell’s weak magnetic field collected by advanced electronic device. The analyzer can work out the customer’s health situation and main problem. According to the checking result, the analyzer can figure out the reasonable treatment recommendation.The quantum resonant magnetic analyzer is the individualized guide ofcomprehensive healthy consulting and updated healthy sciences, and its characteristics and advantages are comprehensive, non-invasive, practical, simple, quick, economical and easy to popularize. With the deep research and scientific development, the analyzer will make great contributions to human health project, and it has broad developing and applying prospect.INSTALLATION INSTRUCTION1.Put the installation disc into CD ROM, and then, the installation process willstart automatically.( If not, please come into the disc file, and double click the document Setup.EXE) The program will run to the window asfollowing(Pic-1).

Auto exposure 简单说明
Auto exposure, Anti-flicker 算法描述一、基本原理1、 理想光源的特点：理想光源可分为两种：一种是光源的强度不随时间发生变化，另一种是光源的强度随着时间发生周期性变化。
2、 日常光源的近似：在日常生活中，主要跟我们相关的光有：太阳光和室内照明所用的光。
其中，由于太阳光具有持续，稳定的特点，为了方便我们的研究，我们认为太阳光为理想光源A 。
目前，室内照明用光一般与当地供电频率相关，其光强一般都随着时间发生变化。
当然现在也有许多照明用光基本没有频率特性或有些地方采用直流供电方式，但那毕竟较少，我们不做讨论。
当前世界上的交流电频率基本都是50Hz 或60Hz ，根据电源电压与功率的关系，我们可以得到室内光源的频率为100Hz 或120Hz 。
简单推导如下： )sin()(0t U t U ω= -- 公式1R t U t P /)()(2=R 为灯泡电阻，为常数-- 公式22/))2cos(1()(sin )()(202202t kU t kU t kU t P ωω-===∴-- 公式3当w = 50Hz 时，P(t)的频率为100Hz ，Y 与P(t)为线性关系，所以室内光源的频率为100Hz或120Hz 。
3、Sensor的相关知识：各个CMOS sensor生产商所采用的技术和材料都不太一样，其基本结构为：滤光片--- 采集三基色入射光光电二极管--- 将光能转换为电子电荷/电压转换器--- 产生电压信号放大器等不同型号Sensor在以上的各个部分都有差别，因此我们不能做出全面的分析。
在这个部分我们的做法是以实验的方法统计曝光时间和曝光程度的关系。
以Samsung的hynix7131gp的CMOS Sensor为例，其感光特性与曝光时间的关系如下图所示。
图3、感光特性与曝光时间的关系曲线从图中可以看出，1．曝光时间增加，图象的曝光程度也在增加；2．当曝光时间较长时，曝光时间的增加量相比相同增加量在曝光时间较短的情况下对Sensor曝光程度的贡献越小；4、Sensor图象的增益调节增益调节指的是调整曝光图象的幅度，但并不能增加图象所携带的信息量，调节Gain值也将改变图象的视觉效果，如图中三条不同曲线所示。

TFT-LCD Flicker发生机理分析简述
上图就是液晶显示基本的四种不同极性转换方式，分别是 “帧反转、行反转、列反转、点反转”。虽然转换方式有差异， 但是针对每个像素来说，每一次画面的刷新，极性就会改变，但 与相邻的像素点极性却不一定要保持一致。以帧反转为例，假设 在 60Hz 频率下帧反转：
此时人看到的画面更新频率为 30Hz，故可以观察到闪烁的现 象。所以提高画面的更新频率可以减小 flicker 的影响，同时， 选择不同的画面极性反转方式也对 flicker 有不同的影响。在基 板的四种转换方式中，帧反转的闪烁现象最为明显，行反转与列 反转不明显，点反转几乎没有。
（一）TFT-LCD 驱动原理 在液晶面板显示中，主要由 Gate 线、Source 线、像素电极 与 Common 电极几个关键组分组成了控制像素偏转的部分。其中 Gate 线的作用是依序将每一行的 TFT 器件打开,使不同的 Source 线同时将一整行的像素充电到各自所需的电压来显示不同的灰 阶，当这一行像素充电完毕后，Gate 线关闭，下一行 Gate 线打 开继续对下一行像素进行充电，以此类推，直到最后一行的像素 也充电完毕再重新打开第一行再次进行充电。Source 线的作用就 是当 TFT 器件打开后给像素电极充电到所需的电压以显示出相对 应的灰阶。 大致示意图如下（CsonCommon 为例）：
实际上，Gate 线每次打开的时间非常短（以常见的 1024*768 分辨率的屏幕为例，60Hz 频率下每根 Gate 线打开的持续时间约 为 21.7 微秒），在 Gate 线关闭的瞬间，电压由高到底急剧变化， 由于 Gate 线与 Source 线之间还存在一个寄生电容 Cgd，当 Gate 线的电压急剧变小时，由于电容的耦合效应，Source 线上的电压 也会受到影响被下拉，从而影响到了显示电极上的电压，最终结 果就是控制液晶旋转的电场受到了影响，改变了画面的亮度（灰
红外监控摄像机设置基本说明
红外监控摄像机设置基本说明红外摄像机是摄像机在镜头和CCD之间加装了一个红外滤光镜,阻挡红外线进入CCD,让CCD只能感应到可见光,这样就使数码摄像机拍摄到的影像和我们肉眼看到的影像一致了。
红外摄像机的作用是对监视区域进行摄像并将其转换成电信号,按规格可分为1/3″、1/2″和2/3″等种类,安装方式有固定和带云台二种。
摄像机基本设置说明:(1)AGC ON/OFF(自动增益控制)：摄像头内有一个将来自CCD的信号放大到可以使用水准的视频放大器，其放大即增益，等效于有较高的灵敏度，然而在亮光照的环境下放大器将过载，使视频信号畸变。
当开关在ON时，在低亮度条件下完全打开镜头光圈，自动增加增益以获得清晰的图像。
开关在OFF时，在低亮度下可获得自然而低噪声的图像。
(2)ATW ON/OFF(自动白平衡)：开关拨到ON时，通过镜头来检测光源的特性/色温，从而自动连续设定白电平，即使特性/色温改变也能控制红色和蓝色信号的增益。
(3)ALC/ELC(自动亮度控制/电子亮度控制)：当选择ELC时，电子快门根据射入的光线亮度而连续自动改变CCD图像传感器的曝光时间(一般从1/50到1/10000秒连续调节)。
选择这种方式时，可以用固定或手动光圈镜头替代ALC自动光圈镜头。
需要注意的是：在室外或明亮的环境下，由于ELC控制范围有限，还是应该选择ALC式镜头;在某些独特的照明条件下，可能出现下列情况：①在聚光灯或窗户等高亮度物体上有强烈的拖尾或模糊现象。
②图像显著地闪烁和色彩重现性不稳定。
③白平衡有周期性变化，如果发生这些现象，应使用ALC镜头。
以固定光圈镜头采用ELC方式时，图像的景深可能小于使用ALC式镜头所获得的景深。
因此，摄像头在完全打开固定光圈镜头而采用ELC方式时。
景深会比使用ALC式镜头时小，而且图像上远处的物体可能不在焦点上。
当镜头是自动光圈镜头时，需要将开关拨到ALC方式。
(4)BLC ON/OFF(背光补偿开关)：当强大而无用的背景照明影响到中部重要物体的清晰度时，应该把开关拨到ON位置。
TFT-LCD Flicker发生机理分析简述
TFT-LCD Flicker 发生机理分析简述文/叶宁戴明鑫李广圣摘要：TFT-LCD 利用电压变化控制液晶盒内电场的强弱，改变液晶分子的排列方向，从而达到了对光透过与否的控制。
然而在液晶显示器显示画面时，经常会出现画面“闪烁、忽明忽暗”的现象，这种现象称为“Flicker”，本文通过对TFT-LCD 的驱动方式等进行简单说明，找寻理论上会产生和影响“Flicker”的因子，以便了解“Flicker”发生的机理。
关键词：Flicker；驱动原理；Feedthoug 电压；漏电流一、引言TFT-LCD 为每一个像素制作了一个半导体开关，可以实现精确控制每个像素点的显示灰阶，拥有比TN 更加快的响应速度以及更为丰富的色彩，画面的刷新频率也更快，故被俗称为“真彩”。
在TFT-LCD 中，主要通过给像素电极施加不同的电压与Common 电极形成一个电场来控制液晶分子的偏转，从而达到遮光与透光的目的，但是如果液晶分子偏转受到影响，画面的显示就会异常，其中一种异常的表现形式就是“Flicker”，也就是闪烁。
二、人眼视觉暂留现象——余晖效应人眼在观察景物时，光信号传入大脑神经需经过一段短暂的时间，当光的作用结束后，视觉形象并不会立即消失，这种残留的视觉称为“后像”，这一现象则被称为“视觉暂留”，也叫做“余晖效应”。
由于余晖效应的关系，要使人眼感受到连续动作的画面，画面的更新频率要至少保持16~24Hz，但由于人眼对光线亮暗的感觉更敏感，实际上30Hz 的画面更新频率下人眼还是可以感觉到画面亮度的差异，直观感受即看到画面在闪烁。
因此要得到更佳的画面品质，画面更新频率越高越好。
那么为什么人会观察到液晶显示器显示时的Flicker 现象呢？这是因为Flicker 产生是由于前后两幅显示画面显示时的亮度（灰阶）不一致，而亮度不同是因为液晶盒的光透过量不同，最后光的透过量又是由液晶分子的偏转程度来决定。
那液晶分子的偏转又受什么影响呢？要了解这个问题，首先要了解一下LCD 的基本驱动原理是怎样的。
