摘　　要：本文基于ZYNQ与非标高分辨率LCoS微显示芯片设计了一个视频驱动方案。首先,对传统显示驱动系统中的输出模块、存储模块进行改进,将存储芯片挂载到ARM端,以节约端口资源;其次,对输出模块进行改进,添加了分辨率转码与型号格式转码设计;最后,基于上述算法进行改进,设计出更节约功耗的方案,每个模块给出实验数据与仿真结果,结合上述实验结果分析方案的可行性并进行板级验证。改进后的显示系统搭建好后可以实现LCoS微显示芯片分辨率为5760×3240、灰度等级为256的视频信号。实验结果表明,本方案通过对存储模块与输出算法的改进,克服了目前非标准高分辨率显示所遇到的两大难题,将1920×1080的HDMI视频信号成功展宽为5760×3240进行输出,效果良好。In the paper,a video drive scheme based on ZYNQ and non-standard high-resolution LCoS micro display chip is proposed.Firstly,the output module and storage module in the traditional display drive system are improved,and the storage chip is mounted on the ARM end to save port resources.Then the output module is improved,and resolution transcoding and model format transcoding de-sign are added.Finally,based on the above algorithm,improvements are made to design a more resource-saving solution.Each module provides experimental data and simulation results.Finally,combining the above-mentioned experimental results,the feasibility of the scheme is analyzed and board-level verification is carried out.After the improved display system is built,the LCoS microdisplay chip can realize a video signal with a resolution of 5760×3240 and a gray level of 256.The experiment results show that this solution overcomes the current two major problems encountered in non-standard high-resolution displays by improving the storage module and output algo-rithm,and successfully expands the 1920×1080 HDMI video signal to 5760×3240 for output,and get good results.
