摘　　要：提出一种基于DLP投影技术的车载集成显示终端设计方案。以嵌入式处理器S5PV210作为控制中心,采用基于DLPC300 DMD芯片的DLP投影仪,软件设计平台基于Linux2.6.38和QT/E4.6,在此基础上设计并完成了软件开发工作并在样机上进行了模拟实验。实验结果表明,系统能够图形化实时显示汽车行驶信息,色彩明亮,视频图像采集清晰,集成化显示避免了驾驶员视线分散,提高了行车安全性。A design scheme of vehicle integration display system based on digital light procession（DLP） technologies is put for- ward. The embedded processor SSPV210 is used as the hardware control kemeLThe DLP ~roiector based on the DLPC300 DMD is used. On the development platform of Linux2.6.38 and QT4.6, software development is designed and implemented.Finally,the simu- lation experiment is carried out on the prototype, the experimental results show that the system can display vehicle informations graphically in real time, which has clear image collection, avoids the events of sight scattered and improves the driving safety and comfort.
