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 design 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 5 760×3 240 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 algorithm,and successfully expands the 1 920×1 080 HDMI video signal to 5 760×3 240 for output,and get good results.
