Abstract
Various embodiments provide a computing device that includes a self-compensating system embedded in the device's display active area. The self-compensating system is composed of a series of PIN diode circuits that include PIN diodes that are formed as active matrix organic light emitting diodes (AMOLEDs) at least partially within the gap between pixels in the display active area.
Claims20
A display for a computing device, the display comprising:
- a substrate;
- an array of pixels formed on the substrate, individual pixels including a corresponding pixel circuit, each pixel circuit including an active matrix organic light emitting diode (AMOLED), wherein individual pixels are separated from other pixels by a gap;
- and
- a plurality of PIN diode circuits formed on the substrate, individual ones of which formed at least partially within respective individual gaps that separate individual pixels,
- wherein each individual PIN diode circuit is associated with one or more pixels of the array of pixels and configured to enable the array of pixels to be self-compensated.
