一、背光板组件1.背光板组件的组成背光板组件主要由4个部分组成,如图1中虚线框所示。各组成部分的功能如下:(1)振荡控制:产生60～100kHz的振荡方波信号。(2)功率放大:把振荡控制部分送来的信号放大到足够点亮灯管的功率。(3)高压输出:把功率放大后的信号升压并转换为正弦波输出,点亮CCFL(冷阴极荧光灯)管。
First, the backlight assembly 1. Backlight assembly components Backlight assembly consists of four parts, as shown in the dashed box in Figure 1 shows. The function of each component is as follows: (1) Oscillation control: Generate 60 ~ 100kHz oscillating square wave signal. (2) Power Amplification: The signal sent by the oscillation control section is amplified to a sufficient level to light the power of the lamp. (3) High-voltage output: boost the power amplified signal and converted to a sine wave output, light CCFL (cold cathode fluorescent lamp) tube.
