摘要
本文介绍一种支持显示高分辨率RGB模拟信号的方法,该方案利用模拟信号传输及采样的特性,通过降低对RGB模拟数据进行采样的时钟频率,实现普通显示端对高分辨率RGB模拟信号的支持。本设计主要分为四个部分:行场同步信号频率及极性检测、查表获取信号时序、降频配置每行总像素、检测DE起始及重新配置信号分辨率。
The method of supporting high resolution RGB analog signal is described in this paper. The scheme is to achieve common display end support for high resolution RGB analog signal through reducing the clock frequency of sampling of analog RGB data by using analog signal transmission and sampling characteristics. This design is mainly divided into four parts： the line field synchronous signal frequency and polarity detection, checking the table to obtain the signal timing, frequency drop configuration of the total pixel, detection of DE start and reconfiguration signal resolu- tion.
