GaP planar monolithic matrix-addressable displays

Display systems that are small in size and require a high density of light-emitting elements can be based on light-emitting diodes. Matrix addressing can be used to minimize the external wires. Interconnections on the display plane can be minimized by the use of a monolithic matrix-addressable display device. A planar processing technique which permits the integration of the light-emitting diode interconnections for a monolithic semiconductor array is presented. The operation of a 5 × 7 monolithic matrix-addressable display device is discussed and demonstrated.
