Patent ID: 10437402

Abstract:
Integrated active-matrix light emitting pixel arrays based displays and methods of fabricating the integrated displays are provided. An example method includes: forming multiple layers on a first substrate to form a light emitting structure, integrating the light emitting structure on the first substrate with a backplane device on a second substrate by connecting a first top layer of the light emitting structure with a second top layer of the backplane device, e.g., by using low temperature bonding, the backplane device including at least one backplane having pixel circuits, and after the integration, patterning the light emitting structure to form an array of light emitting elements each conductively coupled to respective pixel circuits to thereby form an array of active-matrix light emitting pixels. A pattern of different color phosphor or different size quantum dots materials can be deposited on the light emitting pixels to form an array of multi-color display pixels.
