Abstract
Over a flexible substrate are deposited stacked pixel layers including a bottom layer of LEDs forming blue pixels, a middle layer of LEDs forming green pixels, and a top layer of LEDs forming red pixels. Each LED die comprises an LED portion and an integrated transistor portion. Applying a voltage to a control terminal of the transistor portion energizes the LED portion. The pixels are substantially transparent, due to the LEDs being microscopic and the pixel areas being much larger, to allow light from the underlying layers to pass through. The three layers of pixels are aligned so that a combination of a single top red pixel, a single underlying green pixel, and a single underlying blue pixel form a single multi-color pixel. The different layers have transparent column and row lines.
