Implementation of a LED display system for high quality video processing

Due to the improvement of LED (Light Emitting Diode) technology, the LED display system for a high quality video has attracted public attention. LED display system for a high quality video requires not only the ability of processing image frame but also of having the image enhancement block for quality. Thus, in this paper, we demonstrate that we are able to improve frame processing when we use a fully-hardwired system adopting FPGA that has advantages of processing fast the video frame and controlling excessive LED modules. Also, our hardwired design shows that it is so effective as to produce a better quality than that by microcontroller-based system, especially when implementing a complex image processing. The proposed system has other properties that can select a particular part of image for display by manipulating DIP switches. Incorporating these advantages and properties, we propose an efficient system architecture integrating the image cropping, video enhancement, DPRAM interface, and LED interface blocks. As a result, we are able to obtain the synthesis result with 20,428 gates.
