摘　　要：对于显示系统地回路干扰严重影响显示质量问题,首先从理论上阐释了接地要求及其重要作用,分析了地回路干扰成因。在此基础上,结合工程实践的成功经验,提出了行之有效的抑制地回路干扰的综合处理策略,使系统显示质量获得保障,可以为显示系统及电子工程的建设、改造提供有益参考。To solve the image problem in display system caused by ground loop interference, firstly, the equipment grounding requirements and its im- portant function are theoretically explained, and the earth loop interference causes is analyzed. As that basis, to ensure the quality of display, in combi- nation with the engineering practices, a comprehensive treatment strategy to suppress loop interference is put forward. As a result, some beneficial refer- ences for construction and transformation of display system and electronic engineering are provided.
