OLED2.4寸显示屏 液晶屏 规格书

1、显⽰器1、显⽰器介绍 显⽰器属于计算机的 I/O 设备，即输⼊输出设备。

它是⼀种将特定电⼦信息输出到屏幕上再反射到⼈眼的显⽰⼯具。

常见的有 CRT 显⽰器、LCD液晶显⽰器、 LED 点阵显⽰器及OLED 显⽰器。

（1）CRT显⽰器 CRT显⽰器是⼀种使⽤阴极射线管（Cathode Ray Tube）的显⽰器。

它主要由五部分组成：电⼦枪、偏转线圈、荫罩、荧光粉层及玻璃外壳。

CRT纯平显⽰器虽然具有可视⾓度⼤、⽆坏点、⾊彩还原度⾼、⾊度均匀、可凋节的多分辨率模式、响应时间极短等LCD显⽰器难以超越的优点，但⽬前已经退出市场。

CRT显⽰器是最早的，以前的⽼电视机⽤的就是CRT显⽰器。

（2）LCD显⽰器 LCD(Liquid Crystal Display)显⽰器，即液晶显⽰器。

相对于上⼀代 CRT 显⽰器(阴极射线管显⽰器)， LCD 显⽰器具有功耗低、体积⼩、承载的信息量⼤及不伤眼的优点，因⽽它成为了现在的主流电⼦显⽰设备，其中包括电视、电脑显⽰器、⼿机屏幕及各种嵌⼊式设备的显⽰器。

LCD显⽰器内部有很多液晶粒⼦，它们有规律地排列成⼀定的形状，并且它们每⼀⾯的颜⾊都不同，分为红⾊、绿⾊和蓝⾊。

这三原⾊能还原成任意的其他颜⾊。

当显⽰器收到显⽰数据时，会控制每个液晶粒⼦转动到不同颜⾊的⾯，从⽽组合成不同的颜⾊和图像。

也因为这样，LCD显⽰器的缺点有⾊彩不够艳和可视⾓度不⼤等。

LCD主要有TFT、IPS、TFD、UFB、STN、DSTN等⼏种类型的液晶显⽰屏： TFT 屏幕是 Thin Film Transistor （薄膜晶体管）的缩写，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"主动地"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。

转 CRT、LCD、PDP、OLED等显示技术对比目前CRT、LCD、PDP、OLED等显示技术对比一、CRT显示器显像管显示器件又称CRT(Cathode-RayTube：阴极射线管)。

CRT作为当前使用最普遍的显示器件在画面清晰度、亮度、显示速度、对比度、彩色还原质量等方面暂时具有独一无二的优势。

CRT发明至今已有1 00多年历史,而彩色CRT自1 950年问世至今亦有50多年了。

到目前为止,CRT已经历球面、平面直角、柱面、纯平面等几代产品。

CRT的基本参数主要是指亮度、分辨率、对比度及色域。

近50年来,平均亮度提高了50倍,其综合性能是迄今为止任何其他显示器件所不及的。

CRT技术虽然已趋成熟,但仍在继续发展,如屏幕超大尺寸及全平面化,工作特性向高亮度及对比度综合BCP发展。

50英寸的大屏幕CRT点距已达到0.63mm,以支持1 92 0×1 080像素的HDTV显示需求。

尽管在各种显示器件中,CRT的性能价格比最好,综合性能也最佳,但是CRT的缺点也是显而易见的。

首先CRT固有的物理结构限制了它向更广的显示领域发展；其次CRT不仅体积和耗电量大,辐射问题也一直困惑着使用者。

为此，生产CRT的公司还在继续完善他们的工艺，如：CRT显示器的厚度减少，即朝着短项"short-neck"发展，阴极、聚焦栅、透镜、荧光粉、偏转线圈、网格过滤器以及显示器中其它的组件仍在不断改进，其目的是提供更出色的显示效果。

厂家也一直努力把CRT显示器的调节控制改进得更为简便，更易于用户理解和操作，CRT显示器技术仍在不断改进，且向绿色环保发展。

二、LCD显示器平板显示器虽然种类很多,但是目前占据统治地位的仍是液晶显示器。

液晶显示器(LCD)无论是在技术发展速度方面,还是在市场占有量方面,在平板显示器中均遥遥领先。

液晶显示器(LCD)是目前唯一在亮度、对比度、色彩、功耗、寿命、体积、重量等综合性能方面全面赶上和超过CRT的平板显示器件。

用户只需通过串口向终端发简单的命令，就可以实现绘图和显示功能，用户代码中无需进行繁琐的计算和操作。

液晶显示器主要的部件和参数解释(1)液晶面板液晶面板是液晶显示器的主要组件，占去了液晶显示近80%的成本。

目前世界上拥有面板制造技术的厂家并不多，只有SHARP（夏普）、SANYO（三洋）、三星、LG-Philips、台湾的友达等厂商拥有核心技术，大多数液晶显示器都是用它们的面板来组装生产的。

面板的质量和身价目前分为三档：日本的三洋、夏普属于一档，多被采用在高端的产品上，如：sony,优派，纯净界等,价格也相对高昂；韩国的三星、LG 与Philips属于二级，多数使用在搭配品牌机出售的显示器上；友达等台湾厂商则属于第三档，也是低端液晶经常采用的面板。

(2)坏点所谓的坏点是液晶面板上，不能正常显示像素点的统称。

液晶面板是由众多显示点组成，靠每个显示点上的液晶物质在电信号控制下改变透光同状态完成的。

在1024×768分辨率下，液晶板共有786432个显示点，如此多的点很难完全保证个别会出现问题。

但以目前技术水平来看如果将有坏点的液晶面板报废，相信液晶显示也只能是橱窗中的天价商品了，因此，坏点的多少成为了面板的分级时的主要据。

厂商一般会避开坏点分割液晶板，把没有坏点或者极少坏点的液晶面板以较高的价格出售，而坏点数目比较多的则低价卖给小厂生产成廉价的产品。

目前主要的分级标准为：面板厂商标准：韩系厂商，3个以下为A级日系厂商，5个以下为A级台系厂商，8个以下为A级主流液晶显示器品牌准：AA级：无任何坏点的LCD显示器为AA级。

A级：3个坏点以下，其中亮点不超过一个，且亮点不在屏幕中央区内。

B级：3个坏点以下，其中亮点不超过二个，且亮点不在屏幕中央区内。

(3)关键指标：对比度液晶面板制造时选用的控制IC、滤光片和定向膜等配件，与面板的对比度有关，对一般用户而言，对比度能够达到350:1就足够了，但在专业领域这样的对比度平还不能满足用户的需求。

相对CRT显示器轻易达到500：1甚至更高的对比度而言。

In/On-Cell/OGS屏幕全面解析深圳鸿佳科技专注于中小尺寸TFT液晶显示屏、LCD液晶显示模块、触摸屏的研发、设计、生产和销售。

产品涵盖了TN、HTN、STN、FSTN、TFT、OLED、触摸屏等系列；其中TFT液晶屏主要有：1.77寸、2.0寸、2.0寸横屏、2.2寸、2.4寸、2.8寸、3.2寸、3.5寸、3.97寸、4.3寸、5寸、5.6寸、7寸、9.7寸、10.1寸等；黑白液晶屏主要有：字符、图形、中文字库等标准或非标准模块。

产品广泛应用于仪器仪表、医疗设备、电力设备、通讯设备、家用电器、工业控制、消费电子、POS 机、手持设备等多个领域。

关于屏幕概念的炒作，从之前的IPS、AMOLED、SLCD的面板之争，到现在清一色标榜自己是OGS全贴合屏幕，如何如何轻薄、透光、图像“浮现”在屏幕上，苹果则貌似更为“高端”，传出了In-cell/On-cell的概念。

煮机做这期关于OGS/In-Cell/On-Cell屏幕的科普，力求通俗易懂，望以最简单的方式让大家了解真相。

要彻底了解In-Cell/On-Cell/OGS等等屏幕，就得先知道屏幕的基本结构组成。

从上到下，屏幕的基本结构分为三层，保护玻璃（最上面橙黄色标注了Cover glass的部分），触控层（图中一点点淡蓝色虚线，标注了X、Y的部分)，显示面板。

保护玻璃没什么好说的，康宁大猩猩玻璃就是。

触控层的话，就是由ITO触控薄膜和ITO玻璃基板组成。

显示面板可细分的程度高，这里只大致排列下：从上到下，分别是上玻璃基板（粉红色标注了Color filiter的区域，即彩色滤光基板），液晶层（蓝条），下玻璃基板（粉红色标注了Array的区域，即薄膜电晶体基板）。

最后，还需要指出的是，保护玻璃/触控层与显示面板之间，一般贴合技术会形成一层空气（即图中标注了Bonding的金黄色区域），如果采用全贴合技术去除这层空气，屏幕反光会大大减少，点亮屏幕时就显得更为通透，熄屏时更加黑沉，没有灰白的观感。

很多人常常看到手机屏幕分辨率名称例如：VGA、QVGA、HVGA、WVGA、FWVGA等等，却不知道到底是什么意思。

首先要搞清楚，分辨率和屏幕大小是两个概念。

屏幕大小如2.1英寸，3.2英寸，3.7英寸等等，是指屏幕对角线的长度。

这和电视机屏幕以及电脑屏幕的大小是一个概念。

而屏幕分辨率是跟屏幕大小无关的。

屏幕的显示实际上是由一个一个细微的点组成的。

分辨率就是指这些显示点的数量多少了。

而VGA、QVGA、HVGA、WVGA、FWVGA等等这些名称，就是说明了具体的分辨率大小。

VGA ( Video Graphics Array )：是指分辨率为640 * 480 ，由此可以看出纵横显示比是4:3。

这个最早是电脑屏幕和电视屏幕的标准。

QVGA （Quarter VGA）：懂英文的朋友一下子就明白了，这是四分之一的VGA。

不过，注意是面积的四分之一。

因此，QVGA 的分辨率就是长宽各是VGA 的一半，也就是320 * 240 ，现实比仍然是4:3。

HVGA （Half-size VGA）：VGA的一半，还是面积的一半，也就是一边为一半，另一边不变。

因此分辨率为320 * 480 （或者480 * 320），纵横比为3:2。

WVGA （Wide VGA）：VGA加宽了。

分辨率800 * 480 ，5:3。

FWVGA （Full WVGA）而目前Milestone等手机采用的FWVGA（Full WVGA）则更宽一些，达到854 * 480，纵横比接近16:9 。

这样的显示主要是为适应当前智能手机终端浏览网页所需。

单纯就屏幕显示来说，分辨率和屏幕大小也不是一点关系没有。

假设屏幕大小一定，那么分辨率越高屏幕显示就越清晰；相同的道理，假如分辨率一定，屏幕越小显示图像也就越清晰。

我们常用的手机屏幕采用的是同笔记本一样的液晶屏，液晶屏幕的分辨率都是固定的，每一个点就是一个像素。

而且手机分辨率并不是指屏幕大小，而且也可以说和屏幕本身的大小没有关系。

手机液晶屏种类解析手机液晶屏种类详解手机液晶屏的种类能够分为: STN屏幕 TFT屏幕 TFD屏幕 UFB屏幕 OLED 屏幕随着彩屏的逐步普遍，手机屏幕的材质也越来越显得重要。

手机的彩色屏幕因为LCD品质和研发技术不同而有所差异，其种类大致有TFT 、TFD、UFB、STN 和OLED几种。

一样来说能显示的颜色越多越能显示复杂的图象，画面的层次也更丰富。

除去上面这几大类LCD外，还能在一些手机上看到其他的一些LCD，比如日本SHARP的GF屏幕和CG〔连续结晶硅〕。

两种相比较属于完全不同的种类，GF 为STN的改良，能够提高的亮度，而CG那么是高精度优质LCD能够达到QVGA 〔240×320〕像素规格的辨论率。

UFB、STN、TFT比较STN是早期彩屏的要紧器件，最初只能显示256色，尽管通过技术改造能够显示4096色甚至65536色，只是现在一样的STN仍旧是256色的，优点是：价格低，能耗小。

TFT的亮度好，对比度高，层次感强，颜色鲜艳。

缺点是比较耗电，成本较高。

UFB是专门为移动和PDA设计的显示屏，它的特点是：超薄，高亮度。

能够显示65536色，辨论率能够达到128×160的辨论率。

UFB显示屏采纳的是专门的光栅设计，能够减小像素间距，获得更佳的图片质量。

UFB结合了STN和TFT的优点：耗电比TFT少，价格和STN差不多。

相关术语：手机液晶屏幕STN〔Super Twisted Nematic〕屏幕，又称为超扭曲向列型液晶显示屏幕。

在传统单色液晶显示器上加入了彩色滤光片，并将单色显示矩阵中的每一像素分成三个像素，分别通过彩色滤光片显示红、绿、蓝三原色，以此达到显示彩色的作用，颜色以淡绿色为和橘色为主。

STN屏幕属于反射式LCD，它的好处是功耗小，但在比较暗的环境中清晰度较差。

STN也是我们接触得最多的材质类型，目前要紧有CSTN和DSTN之分，它属于被动矩阵式LCD器件，因此功耗小、省电，但么应时刻较慢，为200毫秒。

笔记本液晶屏材质种类介绍现在的笔记本液晶屏种类有哪些?不同材质的屏幕有什么区别?以下是店铺为你精心整理的笔记本液晶屏材质种类介绍，希望你喜欢。

笔记本液晶屏材质种类笔记本液晶屏从做工和材料上分为LCD(狭义的)和LED两种，OLED因为是不同的显示技术，所以OLED笔记本屏幕不在比较范围。

笔记本LCD屏和LED屏的区别LCD液晶显示器是Liquid Crystal Display 的简称，LCD的构造是在两片平行的玻璃基板当中放置液晶盒，下基板玻璃上设置TFT(薄膜晶体管)，上基板玻璃上设置彩色滤光片，通过TFT上的信号与电压改变来控制液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。

优点：显示面板薄(平板型结构)，电磁辐射小，被动显示型(无眩光，有助于眼睛健康)，显示信息量大，易于彩色化，寿命长(这种器件几乎没有什么劣化问题，因此寿命极长，但是液晶背光寿命有限)。

缺点：色彩不够艳丽。

LED是Light Emitting Diode 的简称，含义是发光二极管，是一种能够将电能转化为可见光的固态的半导体器件，它可以直接把电转化为光，而且LED显示器更加省电，更加耐用，使用寿命长，亮度高而发热少，而且是属于环保型绿色照明光源，而且它的做工技术更高!LCD液晶显示屏按照控制方式不同可分为被动矩阵式LCD及主动矩阵式LCD两种。

被动矩阵式LCD：被动矩阵式LCD在亮度及可视角方面受到较大的限制，反应速度也较慢。

由于画面质量方面的问题，使得这种显示设备不利于发展为桌面型显示器。

被动矩阵式LCD又可分为TN-LCD(Twisted Nematic-LCD，扭曲向列LCD)、STN-LCD(Super TN-LCD，超扭曲向列LCD)和DSTN-LCD(Double layer STN-LCD，双层超扭曲向列LCD)。

主动矩阵式LCD：目前应用比较广泛的主动矩阵式LCD，也称TFT-LCD(Thin Film Transistor-LCD，薄膜晶体管LCD)。
