摘要
本文在介绍ＥＤＵ－７６６显示组件总体工作原理的基础之上，重点对显示组件内部的Ａ２视频处理电路卡硬件作了较详细地分析。文中将视频处理电路又分为彩色解码、亮度控制和视频输出三个部分，并力图打破只分析方块图的框框，给出更接近实际的论述及原理电路。
Starting from an introduction to the general principle of the EDU-766 Display Unit, this paper presents a detailed analysis of the hardware of the A2 video processing circuit card, further divides the video processing circuit into three parts: colour decode,brightness control circuit and video output circuit, and in addition to an analysis of the function of the block drawing gives a minute description of the more practical circuit illustration.
