ABSTRACT:
A color display system for use in stadiums, arenas or streets has a matrix of three-primary triads of light-emitting elements controlled by electric signals for displaying images, characters, and/or other patterns in colors. The color display system comprises display units arrayed in horizontal rows and vertical columns and each having simplified electric connector means for external electric connection and means for effectively cooling the light-emitting elements which are packed at high density. Each of the display units has two horizontal rows of light-emitting elements mounted on a front panel of a display unit body, a control circuit housed in the body, and electric connector means mounted on a rear panel of the body. The display units are located closely in each horizontal row and spaced at intervals in each vertical column. A ventilator is disposed behind the display units for cooling the light-emitting elements. Various support arrangements are provided for stably supporting the display units which may have an increased depth.
