摘　　要：设计了一个车载5.6in模拟类型TFT-LCD显示系统。以视频解码IR3Y29BM、时序控制HX8801、小尺寸专用电源芯片LTC3450为主要功能模块,配合外围VCOM放大/调整、场同步分离、LPF/VCO电路,实现了将复合视频(PAL/NTSC)转换为模拟TFT-LCD显示所需的R/G/B、场同步、行同步、VCOM等信号,使A056DN01 TFT-LCD模块实现了复合视频输入的高质量显示,得到了一种结构简单、成本低廉、灵活可行的车载显示解决方案。This article has designed a 5.6 'analog car-mounted TFT-LCD display system. The main function module includes the composite video decoding IR3Y29BM,the sequential controlling HX8801,the power source LTC3450,working in the VCOM amplified/adjust,sync separator and the LPF/VCO circuits and so on,can translate the composite video to the R/G/B,vsync,hsync and the VCOM signals which the TFT-LCD need. It received a good quality display of the A056DN01 TFT-LCD,and abtained a simple,low cost,agility and doable resolvent of the car-mounted display.
