Recently, flat panel display technique becomes the primary display technique. In some special instances, flat panel display technique is blocked in certain problems, such as the display control performance to price ratio and the display resolution. Based on LED display technique, this paper makes a study of the above issues.A single CPU soft-scan controller was designed aiming at the display interruption and the dithering problem of the simple LED information display during the period of the single CPU soft-scan controller communicating with the computer. The display control of single and double color LED display is accomplished, and the display interruption and the dithering problem of the single CPU soft-scan LED information display is solved successfully.The image optimizing technique based on pixel reorgnization was discussed based on the chroma theory of full color LED display and the driving technique of LED color array display, and a static simulation system using the image optimizing technique based on pixel reorgnization was designed based on the single CPU soft-scan display controller.Pixel reorgnization technique was combined with the real time image processing system of TDS642EVM, low resolution image sampling of the high resolution image and the organization and processing of the display data is accomplished by the DSP, color array LED display is controlled through the GPIO interface of the image processing simulation system, image optimizing technique of video LED real time display is accomplished.The research work of this paper laid the foundation for color array super resolution display technique to some extend, while the system itself had a wide market foreground.
