A giant outdoor, full color display system has been developed, the display screen consisting of a matrix array of newly developed light emitting tubes. Each tube is a flood beam CRT, which works as a single picture element (one color), having a single red, green or blue phosphor. The tube is enveloped by a colored glass bulb, to maintain high contrast in bright daylight. It has many superior characteristics and features high color fidelity, low power consumption and long life. It is most suitable for outdoor color display.
