Abstract: Display panel stack-up structures are described. In an embodiment, a display panel includes a substrate, a light source, and a multiple layer thin film encapsulation over the light source. In an embodiment, the display panel additionally includes an anti-reflection layer over the light source. In an embodiment, an incoherence layer is located within the thin film encapsulation.

Abstract: An electronic device may be provided with a display. A content generator may generate frames of image data to be displayed on the display. The display may have an array of pixels that emit light to display images. The pixels may contain light-emitting devices such as organic light-emitting diodes, quantum dot light-emitting diodes, and light-emitting diodes formed from discrete semiconductor dies. As a result of aging, the light producing capabilities of the light-emitting devices may degrade over time. The electronic device may have a temperature sensor that gathers temperature measurements and an ambient light sensor. A pixel luminance degradation compensator may apply compensation factors to uncorrected pixel luminance values associated with the frames of image data to produce corresponding corrected pixel luminance values for the display. The compensation factors may be based on aging history information such as pixel luminance history, ambient light exposure, and temperature measurements.
