THE FULL COLOR LED ELECTRONIC DISPLAY BOARD CONTROLLER

摘要

PURPOSE: A full color LED electronic display board controller is provided to make response speed fast by dividing a controller into four sub-modules to control the them. CONSTITUTION: A DVI single input unit(1) divides an image signal into an R,G,B signal of 7 bit. A write address generator(2) generates an image address related to an inputted image signal. A write address converter(3) converts image output address of an LED module. An RGB data multiplex synchronizes the R,G,B of 7 bit signal with 40~50Hz clock. A read address generator(5) reads data of the minimum unit.
