Color display system utilizing a matrix arrangement of triads
First Claim
1. A color display system comprising:
- (a) a plurality of display units each composed of a body having a front panel, a rear panel, and a pair of rear side recesses, said front panel supporting a plurality of sockets thereon, and a plurality of light-emitting elements mounted respectively in said sockets and capable of emitting light of three primary colors, said light-emitting elements being grouped into a horizontal array of triads of said light-emitting elements on each of said display units, a control circuit unit housed in each said body for controlling said light-emitting elements, said control circuit unit including a printed-circuit board electrically connected to said sockets, and electric connector means mounted on said body and electrically connected to said control circuit unit for external electric connection; and
(b) support means for supporting said display units as a matrix of horizontal rows and vertical columns, said support means comprising vertical posts positioned in said rear side recesses in adjacent display units in each of said horizontal rows, said adjacent display units being mounted on said vertical posts.

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.
