Abstract

See full text

A display comprising a light emitting OLED stack on top of a silicon-based backplane with individually addressable pixels and control circuitry wherein the control circuitry of the silicon-based backplane comprises at least one driving transistor where a first terminal of the driving transistor is electrically connected to an external power source VDD, and the second terminal of the driving transistor is electrically connected to the bottom electrode of the OLED stack; wherein the gate of the driving transistor is controlled by a data signal which supplied by a scan transistor controlled by a signal from select line SELECT1; and the control circuitry additionally comprises a protection circuit comprising a bipolar junction transistor. There can be a switch transistor between the scan transistor and the gate of the driving transistor for microdisplay applications. The OLED stack can comprise two or more OLED light-emitting units.
