Display devices are classified into plasma, liquid crystal, light emitting diode and cathode ray tube types according to the display device used.
CRT（Cathode Ray Tube的简称）阴极射线管显示器的工作原理是通电后灯丝发热，阴极被激发，发射出电子流，电子流受到带有高电压的内部金属层的加速，经过透镜聚焦形成极细的电子束，打击在荧光屏上，荧光粉受到高速撞击之后发光。The working principle of the CRT (Cathode Ray Tube) cathode ray tube display is that the filament heats up after the power is turned on, the cathode is excited, and the electron flow is emitted. The electron flow is accelerated by the internal metal layer with high voltage and is focused by the lens to form a very thin The electron beam hits the phosphor screen, and the phosphor glows after being hit at high speed.
LCD （ Liquid Crystal Display 的简称）液晶显示器。与CRT的原理完全不同的是，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CF（彩色滤光片）。目前主流的LCD是TFT-LCD（薄膜晶体管液晶显示器），是由原有的液晶显示技术扩展而来的。LCD (short for Liquid Crystal Display) liquid crystal display. The principle of the LCD is completely different from that of the CRT. The LCD structure is to place a liquid crystal cell between two parallel glass substrates, with TFT (thin film transistor) set on the lower substrate glass and CF (color filter) on the upper substrate glass.

其中TFT-LCD主动式液晶显示器中，每个子像素具有一个TFT，其栅极(Gate)连接至水平扫描线，漏极(Drain)连接至垂直方向的数据线，源极(Source)则连接至像素电极。在水平扫描线上施加足够的电压，会使得该条水平扫描线上的所有TFT打开，此时该条水平扫描线上的像素电极会与垂直方向上的数据线连通，从而将数据线上的显示信号电压写入像素，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。TFT液晶为每个像素都设有一个半导体开关，以此做到单独的控制一个像素点，液晶材料被夹在TFT玻璃层和颜色过滤层之间，通过改变刺激液晶的电压值进而控制液晶分子的转动方向，从而控制每个像素点偏振光出射与否而达到显示目的，控制最后出现的光线强度与色彩。Among them, in the TFT-LCD active liquid crystal display, each sub-pixel has a TFT, the gate is connected to the horizontal scan line, the drain is connected to the vertical data line, and the source is connected to Pixel electrode. Applying enough voltage on the horizontal scan line will turn on all the TFTs on the horizontal scan line. At this time, the pixel electrode on the horizontal scan line will be connected to the data line in the vertical direction, thereby connecting the data line The display signal voltage is written into the pixels, and the rotation direction of the liquid crystal molecules is controlled by the signal and voltage changes on the TFT, so as to control whether the polarization of each pixel point is emitted or not to achieve the display purpose. TFT liquid crystal is equipped with a semiconductor switch for each pixel to control a pixel individually.
