摘　　要：分析了液晶电视驱动电路的视频解码、去隔行处理和图像缩放等核心关键技术。通过比较相应的视频处理芯片的性能和优缺点提出了一套高端液晶电视机驱动电路设计方案。该方案可将10路输入信号分别进行相应处理,转换成液晶显示屏的数据格式,并以多种显示布局进行显示,包括单画面、画中画(PIP)和画外画(POP)等多种方式。In this paper, we analyze the key technologies such as video decoding, de-interlacing and image scaling for the design of an LCD driver board. We present a solution based on analyzing the performances and features of corresponding processing chips, and have successfully developed a driver board for high-end LCD TV. The system is designed to process 10 input signals and converts them to meet the data format need of FPD devices. Various display layouts such as Single Picture, Picture-in-Picture(PIP) and Picture-Off-Picture(POP) are supported.
