常见的LCD电路由几块IC组成,其电路结构如图1所示。即一块面板、一块主板、一块电源模块与逆变器板、一块键控信号板。各IC的作用如下:1.主板电路主板电路由控制液晶面板的逻辑驱动输出电路、OSD显示电路、背光灯控制电路以及PANEL供电控制功能电路等组成,它是LCD的核心电路,只有主板产生信号后高压板才能工作,再推动背光灯电路使背光灯发光。2.PWPC板模块PWPC板模块又称电源模块与逆变器,它由两大部
Common LCD circuit consists of several IC components, the circuit structure shown in Figure 1. That is a panel, a motherboard, a power module and inverter board, a key signal board. The role of each IC are as follows: 1. Motherboard circuit board circuit by the control of the LCD panel logic driver output circuit, OSD display circuit, backlight control circuit and PANEL power control circuit and other components, which is the core of the LCD circuit, only the motherboard generates a signal After the high-pressure plate to work, and then promote the backlight circuit so that the backlight light. 2.PWPC board module PWPC board module, also known as power module and inverter, which consists of two parts
