摘　　要：介绍了LCoS芯片在电视接收系统中的应用,重点讨论了LCoS芯片的结构与特点。自主开发的LCoS模块采用模拟视频接口、兼容隔行和逐行扫描方式,可以简化系统电路设计,降低系统功耗。同时论述了LCoS微型电视机在信号接收、模拟视频处理、时序控制和音频电路等方面的特点,并给出了相关电路的设计方案。The application of LCoS microdisplay in TV receiver system was introduced. The structure and features of LCoS chip were discussed. In order to reduce system's complexity and consumed power, the LCoS modules made by ourselves have analog video interface circuit and support both interleaved and non-interleaved TV signal. The scheme of UHF receiver, video conversion, LCoS interface controller and audio circuit of subminiature TV receiver were discussed.
