ABSTRACT:
A composite semiconductor light-emitting display array is disclosed in which light is emitted and observed through a light-transmissive planar array of light-emitting devices. The latter are preferably LED's which are formed in a monolithic transparent single crystal such as GaP. Light is generated at the back of the single crystal, but is observed through the front of the crystal. The crystal with its array of LED's is directly interconnected with monolithic integrated circuit, resulting in a composite sandwich structure with interconnections sandwiched between the LED array and the integrated circuit. The latter comprises an array of memory elements such as flip-flops for selectively energizing the light-emitting devices, obviating the need for large peak currents in the planar display.
