量子点QLED深度解析

量子点QLED电视解析或成LED后又一背光革命2014年12月04日过去10年，液晶技术成为显示领域的唯一主宰，未来10年，被誉为次时代显示技术的OLED(Organic Light Emitting Diode，有机发光二极管)理应取缔液晶技术，成就一番霸业，就像当年液晶技术取缔体积庞大的CRT技术一样。

然而，液晶技术并不愿坐以待毙，2015年将实现终极进化，如果您想知道什么才是液晶的“完美形态”，请不要错过这篇文章。

液晶是一种自身不能发光的物质，需借助要额外的光源才能工作，这一物理特性是无法改变的，因此液晶技术的“终极进化”自然需要从背光系统下手。

液晶技术的背光系统主要经历了CCFL(Cold Cathode Fluorescent Lamp，冷阴极荧光灯管)和WLED(White Light Emitting Diode，白色发光二极管)两个阶段。

量子点QLED将液晶技术进化至“完美的终极形态”2015年，液晶技术将迎来背光系统的“终极进化”——量子点QLED技术，无论是性能还是功耗都有革命性的突破，然而，考虑到液晶技术先天物理特性完全处于劣势，量子点QLED背光极有可能是继CCFL背光和WLED背光之后，液晶发展史上的最后一次革命，这也是我们将其定义为“终极进化”的原因。

2015年：三星将引领量子点QLED技术做强做大幕可靠消息，电视领域的龙头老大，三星将会在2015年推出基于量子点QLED背光技术的液晶电视(意味着三星将无限期搁浅OLED 电视计划)，国产方面TCL最快年底就会上市量子点QLED电视产品，LG Display作为顶尖的液晶面板制造商，已经宣布量子点QLED面板将会量产，此外还有京东方、华星光电等面板厂都会力挺量子点QLED背光技术。

那么，量子点QLED背光技术为何能够令如此多的巨头为之倾倒呢？量子点QLED：技术原理/发展历程●量子点QLED背光技术QLED是“Quantum Dot light Emitting Diode”的简写，中文译名是量子点发光二极管，亦可称量子屏显示技术，这是一项介于液晶和OLED之间的新型技术，原理是通过蓝色lED光源照射量子点来激发红光及绿光，QLED核心技术为“Quantum Dot(量子点)”，量子点由锌、镉、硒和硫原子构成。

液晶显示器TN、TFT、STN和TFD详解!

以前发表过关于液晶显示器的文章，但感觉不如下面的内容清晰，所以现在给大家参考参考！液晶显示器的分类。

常见的液晶显示器分为TN-LCD(Twisted Nematic-LCD，扭曲向列LCD)、STN-LCD(Super TN-LCD，超扭曲向列LCD)、DSTN-LCD(Double layer STN-LCD，双层超扭曲向列LCD)和TFT-LCD(Thin Film Transistor-LCD，薄膜晶体管LCD)四种。

其中TN-LCD、STN-LCD和DSYN-LCD三种基本的显示原理都相同，只是液晶分子的扭曲角度不同而已。

STN-LCD的液晶分子扭曲角度为180度甚至270度。

而TFT-LCD则采用与TN系列LCD截然不同的显示方式。

TN由于无法显示细腻的字符，通常应用在电子表、计算器上。

作为显示器TN系列的液晶显示器已基本被淘汰，STN由于扭转角度较大，字符显示比TN细腻，同时也支持基本的彩色显示，多用于液晶电视、摄像机的液晶显示器、掌上游戏机等。

而随后的DSTN和TFT 则被广泛制作成液晶显示设备，DSTN液晶显示屏多用于早期的笔记本电脑，由于支持的彩色数有限，所以也称为伪彩显。

TFT则既应用在笔记本电脑上，又逐步进入主流台式显示器市场。

三、TFT液晶显示器的原理。

TFT液晶显示器与TN系列液晶显示器的原理大不相同，但在构造上和TN液晶仍有相似之处，如玻璃基板、ITO膜、配向膜、偏光板等，它也同样采用两夹层间填充液晶分子的设计，只不过把TN上部夹层的电极改为FET晶体管，而下层改为共同电极。

在光源设计上，TFT的显示采用“背透式”照射方式，即假想的光源路径不是像TN液晶那样的从上至下，而是从下向上，这样的作法是在液晶的背部设置类似日光灯的光管。

光源照射时先通过下偏光板向上透出，它也借助液晶分子来传导光线，由于上下夹层的电极改成FET电极和共通电极。

在FET电极导通时，液晶分子的表现如TN液晶的排列状态一样会发生改变，也通过遮光和透光来达到显示的目的。

液晶显示器背光类型及优缺点(LCD、CCFL、LED)

液晶显示器背光类型及优缺点（LCD、CCFL、LED）液晶背光显示原理液晶不同于等离子的最大区别就是液晶必须依靠被动光源，而等离子电视属于主动发光显示设备。

目前市场上主流的液晶背光技术包括LED(发光二极管)和CCFL(冷阴极荧光灯)两类。

冷阴极荧光灯管（Cold Cathode Fluorescent Lamp；CCFL）传统的液晶显示器都是采用CCFL(冷阴极荧光灯管)背光。

CCFL的背光设计主要有两种：“侧入式”与“直落式”，不过侧入式因光导设计使得光折损率较高，进而让背光亮度受限，面板尺寸越大时亮度就越低，仅适合8英寸～15英寸的TFT LCD面板，也就是Laptop、Desktop等个人观赏之用，但在居家观赏的LCD TV大尺寸上面时，侧入式的亮度将难以满足，取而代之的是直落式。

不过，越大尺寸的LCD，其背光模组所占的成本比重就越高，所指的是正是直落式CCFL背光模组，根据统计，同样是使用直落式CCFL背光模组，在15英寸时背光模组仅占整体成本的23％，但是到30英寸时就增至37％，且推估到57英寸时，背光模组所占的成本就会达到50％。

所以，直落式CCFL 背光仅适合用在30英寸左右的中型尺寸LCD TV，不适合用在更大面积的设计上。

同时，CCFL是运用水银气体放电来产生照明，虽然目前欧盟订立的RoHS规范，只要对“水银”剂量在标准以下仍可接受，但无人能保证日后可能将标准提高至零含量（完全不准使用），届时CCFL将无法使用，或必须改行无汞式 CCFL。

即便无汞式CCFL在技术上可行，但CCFL依旧是密闭光管性的气体放电式电子照明，光管对外力的抗受性有限，较大的冲撞将使光管破裂，使照明失效，相对的其他固体式电子照明（如LED）则无此顾虑。

另外，由於直落式不需要用导光板，也较无光折损问题，所以也不需要增亮膜，特别是增亮膜属少数业者的专利技术，价格昂贵，直落式可以省去导光板与增亮膜，此有助於成本降低。

液晶显示器光延迟测试方法及其应用

液晶显示器光延迟测试方法及其应用李海玲1* 荆海1(1.中国科学院长春光学精密机械与物理研究所北方液晶工程研究开发中心，吉林长春130033，Email：ciomp_lihl@)摘要:ASTN（advanced super twisted nematic）是应用到汽车电子的关键显示器件，其核心技术是采用TEP光延迟膜对STN盒进行补偿。

为在ASTN制造过程中控制STN液晶盒与TEP膜的光延迟值(d△n)尽量一致，本文提出一种新的测试液晶显示器光延迟的方法，该方法采用白光作为光源，通过改变起偏器和检偏器的角度获得白光照射下的透射光光谱，利用琼斯矩阵理论获得的分析方程对液晶盒的光延迟值进行分析计算，测出精确数值后用TEP膜对液晶盒进行光学补偿，获得了较清晰的显示图像。

本文中的实验使用白光光源代替激光光源经济实惠，该测试方法考虑了环境光及光源对测试结果的影响，实验装置操作简单，测试快速，准确，误差小，可重复性高。

关键词：液晶显示器; 光延迟; ASTN; 补偿膜1 引言21世纪，汽车已成为人们生活中不可或缺的代步工具，而电子车载显示技术的诞生更是给人们带来了更多的驾驶乐趣。

随着人们对车载显示器各种性能的要求不断提高，显示器的信息密度及其复杂性也在日益上升，ASTN就是为了满足这些需求而诞生的新型车载显示技术，其结构是在STN（超扭曲液晶）液晶盒外贴一层液晶光学补偿膜TEP对其视角、对比度、温度等进行补偿。

液晶盒和TEP的配置要求：扭曲角相同但扭曲方向相反且要有相同的∆nd 值，扭曲角的误差对决定△nd值的影响较小，所以要精确严格地测试液晶盒的光延迟值，以便补偿膜对液晶盒进行更好的光学补偿。

过去有许多关于△nd测试方面的文献发表[1-8]，如位相补偿法[1]，但该方法需要用不同波长重复测量操作，所以有点复杂耗时；又如波片或偏振片旋转法[2-3]，对于测量低盒厚较准确;光学外差法[4]，但是该方法测试设备比较昂贵和复杂。

显示技术发展历程及市场变革

显示技术发展历程及市场变革一、技术发展历程在2013年FPD峰会上，京东方董事长王东升将显示技术进行了一个分类，将CRT 和PDP归类为真空显示；把TFT-LCD、AMOLED、柔性显示等归类为半导体显示。

半导体显示是指通过半导体器件独立控制每个最小显示单元的显示技术统称。

它有三个基本特征：一是以TFT阵列等半导体器件独立控制每个显示单元状态；二是主要应用非晶硅(a-Si)、低温多晶硅(LTPS)、氧化物(Oxide)、有机材料(Organic)、碳材料(Carbon Material)等具有半导体特性的材料；三是主要采用半导体制造工艺。

与半导体显示技术和产品相关的材料、装备、器件和相关终端产业链统称为半导体显示产业。

王东升总结LCD替代CRT、PDP的原因为“TFT-LCD脱颖而出是因为它顺应了半导体技术替代真空电子技术这一历史大趋势。

”1.1从CRT到LCD/PDP：平板显示与球面显示的竞争1897年CRT诞生，CRT包含一个能够通过电子束触及磷光表面创造出图像的真空管。

之后，此项技术被用于早期电视和电脑显示器上显示图像，一直到20世纪80-90年代CRT逐步被LCD显示所替代，到目前为止CRT已基本退出历史舞台。

1964年首个LCD(液晶显示器)和首个PDP（等离子显示器）双双问世。

LCD技术使得平板显示成为可能。

1972年首台液晶电视的诞生。

2005-2006年LCD液晶显示的销售份额超过CRT，成为显示主流技术，到2010年市场上已基本没有CRT产品。

CRT被淘汰的原因：由于本身重最重且很厚，加之结构(阴罩技术的限制)三基色荧光粉不能做小，因此无法实现屏幕大型化和轻便化以及像素性高清晰显示(只能达到800×600像素)，还有闪烁、X射线辐射、几何失真、清晰度和亮度不高等缺陷。

CRT无法在新兴市场-笔记本电脑屏幕取得竞争优势，不能适应大屏化、轻便化与高清化的要求，同时非常成熟的技术也无法取得更多的技术红利，迫使厂商在性能不完全占劣势的情况下完全停产。

分析：
分辨率决定画面的清晰程度，液晶显示器的分辨率相对较高，画面更细腻，可显示更多内容。
2.分辨率
显示屏是用来输出高清晰图象和视频的，因此清晰度也是非常重要的，对于显示技术，考察清晰度的高低，关键看分辨率的大小。目前，对于大屏幕液晶而言物理分辨率可达到2024×1080，而大屏幕等离子的分辨率依然停留在853×480，而且对于要求单屏多窗口显示时，液晶画面的效果明显好于等离子，与此同时液晶屏克服了等离子屏在低灰度条件下闪烁的问题，所以从分辨率和清晰度的角度看，等离子要略逊液晶一畴。
ቤተ መጻሕፍቲ ባይዱ 5. 亮度
显示图像清不清晰也和亮度有一定关系，如果亮度不足，很多细节就黑乎乎的一片，什么也看不清了。液晶的图像依靠的是液晶板背面的灯管透过液晶板形成图像，早些时候，亮度一直是困扰液晶显示的一个大问题，提高亮度的方法有两种，一是提高液晶板的光通过率，但是这个是有极限的，提高的空间已不大。新型的液晶板已经普遍采用了多支灯管的技术，亮度有很大提高，在相同的参数下，液晶的明亮度效果也要稍好一些。
优点：高分辨率、厚度薄、重量轻、低能耗、长寿命、无辐射。
缺点：拼接缝稍大。
液晶和等离子显示技术
目前主流的平板显示技术主要有液晶显示技术和PDP等离子显示技术。下面，我们就从几个方面比较一下这两种显示技术。
1.使用寿命
大屏幕显示器由于其不菲的造价，所以使用寿命成为其首要问题，理论上讲液晶和等离子显示屏的寿命都可以达到6万小时，不过由于这两种显示技术的发光原理不同，使得实际应用中差异很大。等离子显示器中的每个像素单元实际上是一个微型灯泡，由于使用白炽灯泡，图像质量会随着使用时间增长而变差，虽然目前的技术能够目前的技术能够使等离, , 子显示器工作时间达到60,000个小时，但可能使用到20,000小时的时候背光就会出故障，导致显示质量下降一半。并且等离子如果长期播放一个固定的图像，会在屏幕上留下一个浅浅的痕迹（残影）也就是“烧屏”，例如，如果观看一信号太久，屏幕一角的台标就可能烙印在屏幕上，在观赏其它信号时仍看得到其残影。通常情况下，连续观看10～20小时就能造成看得见的残影，截至目前这个问题还没有完美的解决方法。由于液晶电视工作原理不同（利用液状晶体在电压的作用下发光成像的原理。组成屏幕的液状晶体有三种：红、绿、蓝三基色，它们按照一定的顺序排列，通过电压来刺激这些液状晶体，就可以呈现出不同的颜色，不同比例的搭配可以呈现出千变万化的色彩），液晶显示一般不存在残影和图象质量下降问题。

PDP 介绍

1.什麼是電漿顯示器(Plasma Display Panel)以下簡稱PDP?2.為何電漿顯示器叫”顯示器”而不叫電視呢?3.LCD或其他的顯示技術是否會很快的取代PDP?4.與其他的顯示器比較，PDP有什麼優點呢?5.PDP又有哪些缺點呢?6.PDP能接受哪些畫面解析模式呢?7.為何PDP會這麼貴呢?8.在網路上買的PDP有何優缺點?9.是否所有的PDP都可叫HDTV呢?10.PDP有分企業用與家用二種嗎?11.PDP的消電量多少?是否每一台都有散熱風扇在夜深人靜時會有呼~呼~的聲音?12.PDP是否會干擾其他家電?13.我要買幾吋的PDP較適合呢?14.PDP的壽命會有多長?15.PDP該有哪些輸入端子呢?16.什麼是DVI?17.什麼是HDCP?18.聽說PDP無法表現全暗(black levels)的畫面是嗎?19.聽說購買PDP需要在買一片附加卡是嗎?20.什麼是Native Resolution?(原始像素矩陣)21.什麼是Scaler?PDP內有Scaler嗎?22.PDP與背投式電視'那一種解析度高?23.AliS是什麼?24.發光體長方形或正方形有差別嗎?25.什麼是校色?我的PDP需要校色嗎?26.什麼是”Artifact”?在PDP上會產生什麼樣的Artifact?27.PDP也有壞點(亮/暗點)嗎?28.PDP能否傾斜式的吊掛在天花板上?1.什麼是電漿顯示器(Plasma Display Panel)以下簡稱PDP? topPDP不同於其他顯示的方式在於它的紅藍綠RGB三原色的發光體不是經由電子槍掃描或背光的明暗(如LCD或投影機)所產生的光，而是每個個體獨立發光的，所以大大的減少所佔的空間。

PDP的發光體內是利用離化的惰性氣體的放電產生紫外線去個別激發RGB三種不同的螢光體而產生不同的RGB三原色的可見光，並利用激發時間的長短來產生不同的亮度。

由於它是每個個別獨立的發光體在同一時間(一張畫面的時間約1/30~1/60秒)一次點亮的，所以特別清晰鮮明。

QLED 下一代的柔性显示技术

QLED：下一代柔性显示器详解CINNO2018-09-08在未来的电子产品中，所有的设备组件将被无线连接到作为信息输入和/或输出端口的显示器上。

因此，消费者对下一代消费电子产品信息输入/输出功能的需求，导致了对柔性和可穿戴显示器的需求将会越来越大。

在众多下一代发光显示器设备中，量子点发光二极管（QLEDs）具有独特的优势，如色域宽、纯度高、亮度高、电压低、外观极薄等。

柔性显示器由于其在移动和可穿戴电子产品（如智能手机、汽车显示器和可穿戴智能设备等）的潜在应用前景，而受到了极大的关注。

柔性显示器具有薄、轻、不易破碎的特点，且形状可变，能在曲面上使用。

2008年，诺基亚宣布了“Morph”的创新移动显示概念，这是一种具有柔性、可弯曲和交互功能的显示。

这也被开发成柔性电子纸的早期原型。

2013年，三星电子展示了第一个基于有机发光二极管（OLED）的曲面电视，其视野广阔、色彩纯度和对比度都非常高。

两年后，它们又发布了一款带有曲面屏（GalaxyS6）的智能手机，该智能手机使用了一个带有触摸传感器的曲面OLED显示屏，以改善用户界面与设备设计。

虽然非平面显示器已经被推广使用，但目前可用的商业化显示器大多是弯曲的显示器，其形状是无法改变的。

而下一代显示器应该是可以以各种形式展现的，如图1所示。

智能眼镜和/或智能隐形眼镜将用于支持增强现实，在眼镜或镜头后面的自然场景中添加显示信息；通过智能手表实时显示，可穿戴传感器可以测量使用者的生命体征（如血压、脉搏、呼吸频率和体温）或其他健康信息；或者以纱线的形式制备的LED织入布料中，用于可穿戴显示器；也可以电子纹身的形式将超薄显示器附着在人体皮肤上；还可以将可弯曲显示器作为能调节的可折叠平板电脑等。

此外，透明的柔性显示器可以用于智能窗户或数字标识，在背景视图中显示数字信息。

图1：未来的柔性和可穿戴显示器在这种下一代显示器的研究领域中，主要的技术目标是开发具有机械变形能力和优异器件性能的LEDs。

液晶屏幕知识

XGA——Extended Graphics Array：这是一种目前笔记本普遍采用的一种LCD屏幕，市面上将近有80%的笔记本采用了这种产品。它支持最大1024×768分辨率，屏幕大小从10.4英寸、12.1英寸、13.3英寸到14.1英寸、15.1英寸都有。
SXGA+——Super Extended Graphics Array：作为SXGA的一种扩展SXGA+是一种专门为笔记本设计的屏幕。其显示分辨率为1400×1050。由于笔记本LCD屏幕的水平与垂直点距不同于普通桌面LCD，所以其显示的精度要比普通17英寸的桌面LCD高出不少。
[DSTN（double-layer super-twisted nematic即双层STN ，过去主要应用在一些笔记本电脑上。也是一种无源显示技术，使用两个显示层，这种显示技术解决了传统STN显示器中的漂移问题,而且由于DSTN还采用了双扫描技术，因而显示效果较STN 有大幅度的提高。由于DSTN分上下两屏同时扫描，所以在使用中有可能在显示屏中央出现一条亮线。

TFT屏幕
TFT ( Thin Film Transistor 薄膜晶体管) ，是有源矩阵类型液晶显示器(AM-LCD)中的一种，TFT在液晶的背部设置特殊光管，可以“主动的”对屏幕上的各个独立的象素进行控制，这也就是所谓的主动矩阵TFT（aCTive matrix TFT）的来历，这样可以大大的提高反应时间，一般TFT的反映时间比较快约80ms，而STN则为200ms如果要提高就会有闪烁现象发生。而且由于TFT是主动式矩阵LCD可让液晶的排列方式具有记忆性，不会在电流消失后马上恢复原状。TFT还改善了STN 会闪烁（水波纹）-模糊的现象,有效的提高了播放动态画面的能力。和STN相比TFT有出色的色彩饱和度、还原能力和更高的对比度，但是缺点就是比较耗电，而且成本也比较高。

逻辑板工作原理

TFT-LCD
•
TFT-LCD（ThinFilmTransistor LCD）： TFT是薄膜晶体管的英语缩语；TFT-LCD是指薄膜晶体管液晶显示器件，可以做到高速度、高亮度、高对比度显示屏幕信息，是目前最好的LCD彩色显示设备之一。TFT的每个像素点都是由集成在自身上的TFT来控制，是有源像素点。因此，不但速度可以极大提高，而且对比度和亮度也大大提高了，同时分辨率也达到了很高水平，下图所示即为一个像素元TFT-LCD组成结构图。图中；最下面是背先源；偏振片；TFT电极板；配像模；液晶层；共用电极；滤色片；偏振片。和前述不同的是控制液晶分子扭曲的电极为TFT电极，为了达到彩色显示的目的，在上偏振片下面增加了RGB三色滤色片，三组扭曲的分子组成一个像素点的显示。
图A就是一个TFT-LCD像素显示的组合，可以看到在这个组合中，有三个TFT-MOS管控制RGB 三色点，图B是一组中的一个子像素电路结构。在图B中；MOS管道栅极接行扫描控制信号；源极接列控制信号（控制液晶分子扭曲的图像信号）；漏极接控制液晶扭曲的TFT电极板，共用线是接上共用电极板（共用电极板和接漏极的 TFT电极板形成的分布电容，电容上的电压就是控制液晶分子扭曲的电压），由于上共用电极板和下TFT电极板之间的分布电容的存在，等效电路如图C和图D所示从结构图中可以看出，在液晶屏中还设有存储电容C，这主要是为了让充好电的电压能保持到下一次更新画面的时候之用，通常，存储电容是由像素电极和公共电极（或栅极）布线组成，也就是说，存储电容是一种像素电极与公共电极（或栅极）走线所形成的平行板电容。对于液晶屏来说，每个像素从结构上可以看做是像素电极和公共电极之间夹一层液晶。图ABC所示为液晶显示屏中一个像素的内部结构与电路符号，图中的存储电容C是由像素电极与公共电极所形成的，图中的Uc为液晶层电容，即液晶材料的等效电容。
