摘要
基于RGB显示屏的架构及接口类型,分析了RGB显示屏辐射发射存在的主要问题以及辐射噪声的形成原因,并针对性的使用滤波电路、扩频IC、增加低通滤波器等整改措施。整改后的RGB显示屏辐射发射测试结果符合EN 55022等级B的要求。
RGB display architecture and interface types based on the analysis of the main problems of RGB radiation and emission display radiation noise causes, and for the use of filter circuit, the spread spectrum IC, low-pass filter and other corrective measures. After the rectification of the RGB display radiation emission test results in line with the requirements of EN 55022 Class B.
