放映机4K技术浅谈
放映机4K技术浅谈作者:来源:《电影中国》2016年第04期近几年随着显示技术的发展4K技术已经不再是一个新鲜的名字,4K技术不断丰富和充斥着我们生活中的方方面面,在近期大热的电影行业,除了一部部票房不断创出新高的国内外大片之外,电影院对画面的放映质量要求和观众的观影感受也在不断的提高。
为了紧跟电影市场的发展步伐,作为放映技术发展的引领者和开拓者的NEC公司,也将在2016年隆重推出,拥有3芯片DLP Cinema 1.38英寸DC4K的三色激光数字放映机NC3540LS-1+。
这样就使得NEC三色激光放映机在拥有2K三色激光产品线的同时,又增加了一条4K三色激光产品线。
作为投影机的显示技术,现在主流的主要有三种,LCD(液晶面板显示技术),LCOS (单晶硅反射式液晶显示技术),DLP(数字光处理显示技术)。
目前应用在数字电影放映技术中采用最多的是DLP技术,DLP技术开发者是TI(德州仪器),NEC公司专注于为行业提供专业的显示解决方案,NEC公司不但是TI(德州仪器)公司在全球范围中授权产生DLP数字放映机三家厂商的其中一家,而且在工程、商务、教育、家用都拥有功能多样化、种类丰富的DLP投影机产品线。
对于NEC的4K三色激光放映机NC3540LS-1+则采用的是三片1.38英寸的DMD芯片来显示4K画面,每个芯片的物理分辨率是4096x2160,三个芯片分别独立对应一种RGB颜色中的一种。
4K DLP Cinema显示技术中的DMD芯片拥有着有别其他显示技术的独特优势,这些优势也使得其可以很好的应对高亮度输出、长时间使用、苛刻的运行环境等诸多显示应用要求。
下面我们来一一了解下。
支持高亮度DMD芯片采用的金属铝片利用不同的偏转角度把光反射到不同的位置实现画面明暗变化,光利用方式则为全反射显示,所以光的利用率较高,也正是由于光线绝大多数都被金属面反射出去了,芯片上的热量堆积就会变的很少,在配上高效的液冷散热,使得芯片可以在高亮高温的环境下任然可以保持一个良好运行状态。

This offers the greater exibility customers require.NaViSet Administrator 2This software is an all-in-one remote supportsolution that runs from a central location and provides monitoring, asset management and control functionality of the majority of NEC display devicesand Windows computers. It is ideal for multi-device installations over larger infrastructures.Dedicated Colour Calibration SoftwareAs the brightness and colour temperature of the LCD change with time, colours may not match across multiple screens. Our dedicated colour calibration software* ensures colour uniformity and delity across mul-tiple screens, creating a perfectly matched image in tiled environments.* NEC Display Wall CalibratorProof of PlayThis function provides accurate proof that displays are working as established and is helpful when checking on the status of the displays installed at a user’s site.Advanced Heat ManagementMonitoring and managing the temperature of each displayis crucial to secure reliability and longevity.DisplayPort Multi-stream FunctionThanks to the multi-stream function of DisplayPort technology, multiple displays can be daisy chained and still be individually controlled. This also makes a 2 × 2video wall with native Ultra High De nition 4K /2K (3,840 × 2,160) possible.Without heat management, displays placed higher on a wall sustain more heat. However, NEC’s advanced heat management ensures uniform heat dissipation.Auto TileMatrix and Auto ID TechnologyAuto TileMatrix and ID features allow you to simply set up the size of the video wall on the rst display, and then automatically scale the content through the remaining displays to set up the entire video wall (of up to 100 displays in a 10 × 10 matrix).Intelligent Wireless Data FunctionThe built-in near eld communication (NFC) chip allows data to be read and written via a mobile phone or tablet PC. Users can signi cantly reduce installation costs as displays can be easily con gured and serviced using the NEC NFC Android app. This is available even when the display is switched off and is especially useful on larger installations.This optional human (motion) sensor accessory (KT -RC2) helps to deliver creative digital signage to end users by allowing for dynamic control of brightness, audio and source inputs while saving operating costs. Auto dimming adjusts the backlight of the LCD automaticallydepending on the amount of ambient light.X464UNS-2• Just one cable each for video and control • Only two cables required for setup• Up to 100 displays can be daisy chainedWith FRAME COMP*Without FRAME COMP* Only available through NEC.*OPS is a standard established by Intel Corporation.OPS*Interface Extension No human (motion) detectedHuman (motion) detectedOther Useful Features and Functions•Landscape /portrait capability •Scheduler w/real-time clock•Intelligent power management system•Power-on delay •Screen saver function •Aspect ratio control •Memo function •Carbon footprint meter•Image and on-screen display ip •Picture-in-picture, Picture-out-picture •Point zoom•Control lock function•6-axis colour adjustments and sRGB standard•Advanced video settings(noise reduction, adaptive contrast)•Colour temperature adjustment•Programmable gamma setting (3 settings)•DICOM simulation•Plug and play (DDC/CI, DDC2B)•HDCP (High-bandwidth Digital Content Protection)•Ethernet and RS-232C control and communication •CRESTRON ROOMVIEW ™•AMX Discovery HTTP server•PJLink •Self-diagnosis •Status log function •Firmware update over LAN•Metal rear cabinet with VESAStandard (FDMIv1) mounting interface •HandlesAC INMain Power SwitchService portAUDIO IN 1, 2DVI IN (DVI-D)EXTERNAL SPEAKERTERMINALSAUDIO OUTLAN ports (RJ-45)REMOTE INDisplayPort connectorsRS-232C (D-Sub 9 pin)VGA IN(mini D-Sub 15 pin)HDMI INTerminalsX464UNS-2。

This device integrates 1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet, and 10Mbps Ethernet network capabilities in a highly flexible package.PurposeThis guide discusses how to install your Web Smart 48+2G-Port 10/100/1000Mbps/SFP Switch.Terms/UsageIn this guide, the term “Switch” (first letter upper case) refers to your Web Smart 48+2G-Port 10/100/1000Mbps Switch, and “switch” (first letter lower case) refers to other Ethernet switches.INTRODUCTIONThis chapter describes the features of the Web-Smart 48+2G-Port 10/100/1000Mbps/SFP Switch and some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology.Gigabit Ethernet TechnologyGigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full-duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software, and trained personnel.The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnets.Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number of operations in the same amount of time.In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow’s rapidly improving switching and routing internetworking technologies. With expected advances in the coming years in silicon technology and digital signal processing that will enable Gigabit Ethernet to eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000-Mbps-capable backbone/server connection creates a flexible foundation for the next generation of network technology products.Fast Ethernet TechnologyThe growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. The non-disruptive and smooth evolution nature, and the dominating potential market base, virtually guarantees cost-effective and high performance Fast Ethernet solutions.100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training.Switching TechnologyAnother approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments.Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which do not compete with each other for network transmission capacity.The switch acts as a high-speed selective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards.Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems.VLAN (Virtual Local Area Network)A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and the need for routers, by using faster switching instead. Other VLAN utility includes:Security, Security is increased with the reduction of opportunity in eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN.Cost Reduction, VLANs can be used to create multiple broadcast domains, thus eliminating the need of expensive routers.Port-based (or port-group) VLAN is the common method of implementing a VLAN, and is the one supplied in the Switch.Features48×10/100Mbps Auto-negotiation Fast Ethernet RJ-45 ports2×10/100/1000Mbps Auto-negotiation Gigabit RJ-45 ports2×mini-GBIC/SFP ports, share with the 2 gigabit copper portsAll RJ-45 ports support auto MDI/MDIX, so there is no need to use cross-over cables or an up-link port Half-duplex transfer mode for 10/100Mbps RJ45 portsFull-duplex transfer mode for 10/100/1000Mbps RJ45 portsStore-and-Forward switching scheme capability to support rate adaptation and ensure data integrityUp to 4K unicast addresses entities per device, self-learning, and table aging1536KBytes packet bufferSupports IEEE 802.3x flow control for full-duplex mode portsSupports Back-pressure flow control for half-duplex mode portsSupports 802.1Q VLANSupports Port-base QoSSupports seven Port-base Trunking groupSupports Port MirroringSupports Port-setting for Speed/Disable, Flow controlEasy configuration via Web BrowserEasy setting via Web Management UtilityStandard 19” Rack-mount sizeUNPACKING AND INSTALLATIONThis chapter provides unpacking and installation information for the Switch.UnpackingOpen the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items:One Web Smart 48+2G-Port 10/100/1000Mbps/SFP SwitchOne AC power cord, suitable for your area’s electrical power connectionsFour rubber feet to be used for shock cushioningScrews and two mounting bracketsCD-Rom with Web Management Utility and User’s GuideIf any item is found missing or damaged, please contact your local reseller for replacement.InstallationThe site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers:Install the Switch in a fairly cool and dry place. See Technical Specifications for the acceptable temperature and humidity operating ranges.Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.Leave at least 10cm (about 4 inches) of space at the front and rear of the hub for ventilation.Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the next section, titled Rack Mounting.When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratching.Rack MountingThe Switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the Switch’s front panel (one on each side), and secure them with the provided screws.Figure 1. Combine the Switch with the provided screwsThen, use screws provided with the equipment rack to mount each Switch in the rack.Figure 2. Mount the Switch in the rackConnecting Network CableThe Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet and it runs both in half- and full- duplex mode using two pairs of Category 5 cables.The Switch also supports 2-Ports Gigabit Ethernet that runs in Auto-negotiation mode and 10Mbps Ethernet or 100Mbps Fast Ethernet that runs both in half- and full- duplex mode and 1000Mbps Gigabit Ethernet runs in full-duplex mode using four pairs of Category 5 Cables.These RJ-45 ports are Auto-MDI type port. The Switch can auto transform to MDI-II or MDI-X type, so you can just make an easy connection that without worrying if you are using a standard or crossover RJ45 cable.There are additional two mini-GBIC ports for optional mini-GBIC/SFP modules.AC PowerThe Switch uses a 100-240V AC, 50-60 Hz AC power supply. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The Switch’s power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected.IDENTIFYING EXTERNAL COMPONENTSThis chapter describes the front panel, rear panel, and LED indicators of the Switch.Front PanelThe figure below shows the front panels of the Switch.Figure 3.

70寸LEDDLP参数
1.1 系统的主要设备技术性能指标1.1.1 佰路-DLP投影单元主要技术参数DLP单元结构图:1.1.2 佰路DLP™投影单元DLP是英文Digital Light Processor的缩写,译作数字光处理器。
这一新的投影技术的诞生,是美国德州仪器公司在拥有、存储数字信息的能力之后,终于实现了数字信息的显示。
DLP技术是投影显示领域划时代的革命,它以DMD (Digital Micromirror Device)数字微反射器作为光阀成像器件,采用数字光处理技术调制视频信号,驱动DMD光路系统,通过投影透镜获取大屏幕图像,与传统的CRT、LCD技术相比,DLP投影技术有如下特点:一、数字优势。
数字技术的采用,使图像灰度等级达256~4096级,色彩达2563~10243种,图像噪声消失,画面质量稳定,精确的数字图像可不断再现,而且历久弥新。
二、反射优势。
反射式DMD器件的应用,使成像器件的总光效率达80%以上,对比度和亮度的均匀性都非常出色。
三、画面优势。
DLP™投影机清晰度高、画面均匀,色彩锐利,它抛弃了传统意义上的汇聚,可随意变焦,调整十分便利,DLP™将为视频投影显示领域翻开新的一页。
大幅度改进了对比度:达到了1700:1,多屏拼接系统的画面更为清晰鲜明。
1000:11700:11) 数字CSC ( Color Space Control ) 色域补偿电路技术:在传统投影机中,画面色彩调整采用白平衡调整,结果导致只有白色一致。
但是在DLP投影系统单元的色彩调整中,由于DLP520机芯采用独家原创的数字CSC ( Color Space Control ) 电路,有效抑制了各画面间三原色的离散,使红绿蓝三基色达到了高度一致,而不仅仅是白色的一致性。
数字CSC补偿前数字CSC补偿后2) 改善了色乱现象单片DLP™投影机是通过三色轮旋转行成彩色图像的,长时间投放RGB 各种颜色,在视线大幅度移动时眼睛会出现视觉残留的现象,也就是光闪色乱现象。
