液晶显示器故障维修大全液晶显示器故障维修大全一、液晶显示器的概念:液晶是一种介于固态和液态之间的具有规则性分子排列及晶体的光学各向异性的有机化合物。
液晶在受热到一定温度的时候会呈现透明状的液体状态,而冷却则会出现结晶颗粒的混浊固体状态,因为其物理上具有液体与晶体的特性,故称之为“液晶”。
液晶显示器实际上就是以液晶为显示模块制作的显示器。
液晶显示器中的液晶体在工作时并不发光,而是控制外部光的通过量。
当外部光线通过液晶分子时,液晶分子的排列扭曲状态不同,光线的通过量就不同,从而实现了亮暗变化,利用这种原理可重现图像。
液晶分子扭曲的大小由加在液晶分子两边的电压差决定,因而可以实现电到光的转换。
即用电压的高低控制光的通过量,从而把电信号转换成光信号,将图像显示出来。
二、液晶显示器的结构:1. 从外观看,液晶显示器主要包括显示器外壳、显示器电源开关、功能按钮、支架及液晶显示屏(PANEL)等。
2. 从内部结构看,液晶显示器主要由驱动板(主控板)、电源板、高压板(有的和电源板设计在一起)、功能面板、VGA接口、DVI接口、液晶面板(包括液晶分子、液晶驱动芯片、彩色滤光片、偏光板、导光板等)、背光灯管组成。
液晶显示器内部结构实物图三、液晶显示器内部1. 驱动板:驱动板也叫主控板,主要用以接收、处理从外部送进来的模拟(VGA)或者数字(DVI)图像信号,并通过屏线送出驱动信号,控制液晶面板工作。
驱动板上主要包括微处理器、图像处理器、时序控制线片、晶振、各种接口及直流电压转换电路等,它是液晶显示器的检测控制中心和大脑。
2. 电源板:电源板的作用是将90~240V的交流电压转变为12V、5V、3.3V 等直流电压,供给驱动板、液晶面板等工作。
3. 高压板(又称升压板、高压条、INVERTER):高压板主要是将主板或电源板输出的12V的直流电压转变为背光灯管启动和工作需要的1500-1800V的高频高压交流电。
有的液晶显示器的电源板和高压板会做在一起,即所谓的电源背光二合一板。
