TFT LCD 面板

什么是TFT液晶显示器？

TFT LCD（薄膜晶体管液晶显示器）采用类似三明治的结构，两块玻璃板之间填充有液晶。.

TFT玻璃上的TFT数量与显示的像素数量相同，而彩色滤光片玻璃上则带有用于生成颜色的彩色滤光片。液晶会根据彩色滤光片玻璃与TFT玻璃之间的电压差而发生移动。 背光模组提供的光量由液晶的移动程度决定，这种移动方式正是为了产生颜色。.

TFT LCD 像素的工作原理

一块 TFT 液晶面板包含一定数量的单元像素，通常称为子像素。每个单元像素都包含一个 TFT、一个像素电极 (IT0) 和一个存储电容 (Cs)。例如，一块 SVGA 彩色 TFT LCD 面板共有 800×3×600，即 1,440,000 个单元像素。每个单元像素以 3m×n 矩阵形式连接到一条栅极总线和一条数据总线。 对于SVGA，该矩阵尺寸为2400×600。.

TFT LCD的结构

生成颜色

TFT LCD 电视的彩色滤光片由三种原色——红色（R）、绿色（G）和蓝色（B）——组成，这些原色均位于彩色滤光片基板上。.

LCD面板是如何产生颜色的？

该彩色滤光片上的元素与TFT阵列基板上的单元像素呈一对一排列。彩色液晶显示器中的每个像素被细分为三个子像素，其中一组 RGB 子像素等于一个像素。（每个子像素由我们此前一直所说的“单位像素”组成。）

由于子像素过于微小，无法单独分辨，因此人眼所见的RGB元素呈现为这三种颜色的混合。在一定条件下，任何颜色都可以通过混合这三种原色来产生。.

使用 n 位 LDI 时，显示颜色总数为 2³n，因为每个子像素可以产生 2^n 种不同的透光率级别。.
