Display with light amplification

Abstract

An integrated OLED display, preferably a microdisplay, comprising a base display that emits a pixelated image and an overlying stacked OLED amplification structure where the OLED amplification structure has at least two light-emitting OLED units separated by a charge-generation layer and a photodiode layer which generates a photocurrent upon exposure to light from the base display as well as the light emitted by the OLED units; wherein the pixelated emission from the base display causes pixelated light emission from the OLED amplification structure. The base display can comprise a single light emitting OLED unit on top of a silicon-based backplane with components nominally rated at 5V or less. The base display emits IR, NIR or red light to which the photodiode layer is sensitive. Cross-talk between the pixels may be controlled by the use of opaque optical dividers.
