CONTROL CIRCUIT OF VARIOUS COLOR EXPRESSION USING THREE COLOR LIGHT EMITTING DIODE DISPLAY BOARD MODULE, IN WHICH ONE THREE-COLOR LIGHT EMITTING DIODE IS CONTROLLED PER UNIT SECOND

摘要

PURPOSE: A control circuit of various color expression using a three color light emitting diode display board module is provided to express images like a photograph or a figure of high resolution using the three color light emitting diode module having a simple structure. CONSTITUTION: According to the control circuit of various color expression using a three color light emitting diode display board module, a memory device address generator(25) converts binary output data of a pixel clock counter part(22) and a horizontal synchronous signal counter part(23) into an address of an image information memory device. A memory device control signal generator(24) generates a control signal of the image information memory device using binary output data of the pixel clock counter part and the horizontal synchronous signal counter part. A display board control signal generator(26) generates a control signal to output images of a display board using binary output data of the pixel clock counter part and the horizontal signal counter part. And a display board color signal control part(27) stores red data and green data and blue data into the image information memory device and outputs them to the display board.
