Abstract
An array of addressable, electrically isolated, light emitting diodes are fabricated in the substrate of a monolithic device. Discrete regions of the array constitute respective pixels of the array. Each array pixel has at least three diodes. Two diodes are commonly addressable and a third diode interleaved between the commonly addressable diodes is separately addressable. Each diode of an array pixel, when addressed is forward biased and produces output light which is emitted from its pixel and forms a light image on a corresponding pixel of an image zone. The selectively addressing of the LEDs of the array pixels causes the addressed LEDs to emit light and provide different gray scale light images at corresponding image zone pixels.
