As one of typical examples, description will be made for a dot matrix-type LED full color display apparatus of 480 vertical lines and 128 horizontal dots. Each of the pixel lamps which are in total 61,440 pieces is an LED multi-color gathered lamp in which LEDs of three primary colors of RGB (red, green and blue) are densely arranged. Pixel data for activating one pixel lamp consists of 8 bits for each RGB, that is, 24 bit data in total, and is capable of full color expression of 16,777,216 colors. The image data for one screen is data of (61,440×24) bits.
