Abstract:
1. An active-matrix electroluminescent device, comprising: a plurality of light-emitting elements laid out over a substrate, each light-emitting element including a first electrode and a second electrode having one or more electroluminescent layers formed there-between, at least one electroluminescent layer being light-emitting, at least one of the electrodes being transparent and the first and second electrodes defining one or more light-emissive areas, and electronic components formed on the substrate connected to the first and/or second electrodes for driving the one or more electroluminescent layers to emit light; a plurality of electrical buses carrying a common signal connected to the light-emitting elements; a plurality of electrical cross-connections intersecting and electrically connecting the plurality of electrical buses; wherein the plurality of light-emitting elements are arranged in groups of four light-emitting elements each, each group forming a quad cell of four neighboring light-emitting elements arranged around intersections of the electrical buses and cross-connections, two light-emitting elements of each quad cell being formed on each side of an electrical bus and two light-emitting elements of each quad cell being formed on each side of an electrical cross-connection; wherein each of the light-emitting elements of each quad cell are connected to the electrical bus or electrical cross-connection separating the light-emitting elements of the quad cell, each quad cell shares a common electrical bus or cross-connection with an adjacent quad cell, and wherein adjacent quad cells sharing a common electrical bus are not separated by a common cross-connection and neighboring quad cells sharing a common cross-connection are not separated by a common electrical bus; and wherein each quad cell comprises a single pixel having four light-emitting elements, a first light-emitting element emitting red light, a second light-emitting element emitting green light, a third light-emitting element emitting blue light, and a fourth light-emitting element emitting white, cyan, yellow, or magenta light.
