Abstract: A system, method, and device for increasing uniformity between displays incorporating components from different manufacturers. Incorporating components from different manufactures in different displays may cause the different displays to appear differently even under similar conditions. By modifying the operating parameters used to drive the display according to performance characteristics for various conditions, displays incorporating components from different manufacturers may be configured to produce a substantially similar picture under similar conditions. The various conditions may include stimulus information, such as temperature or touch activity.

Abstract: To reduce image artifacts induced by temperature variations associated with display pixels of an electronic display, processing circuitry may process temperature sensing data to obtain an average temperature and a temperature distribution of the electronic display. Based on the processed temperature data, the processing circuit may adjust a reference voltage applied to the display pixels to compensate for the average temperate. To further correct for the image artifacts, the processing circuitry may transform image data to luminance domain. Based on the processed temperature data, the processing may adjust luminance vales of the image data to compensate for the temperature distribution.

Abstract: Hybrid architectures and method methods of operating a display panel are described. In an embodiment, row driver and pixel driver functions are combined in a group of backbone hybrid pixel driver chips, wherein global signal lines are distributed to the backbone hybrid pixel driver chips, where the global signals are manipulated and distributed to a row of pixel driver chips.

Abstract: An electronic device may display image content via an electronic display by controlling light emission from display pixels of the electronic display. A processor of the electronic device may receive image data destined for a defective display pixel (e.g., dim pixel, dead pixel). The processor may convert a gray level of the image data into a luminance domain to generate a target luminance that would have been emitted by the defective display pixel had the display pixel not been defective. After selecting a compensation mask, the processor may distribute the target luminance of the defective display pixels to nearby non-defective pixels of the electronic display to conceal the presence of the defective display pixel.

Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed on a display panel substrate. A display panel may extend continuously across the display or multiple display panels may be tiled in two dimensions to cover a larger display area. Interconnect substrates may have outwardly facing contacts that are electrically shorted to corresponding inwardly facing contacts such as inwardly facing metal pillars associated with the display panels. The interconnect substrates may be supported by glass layers. Integrated circuits may be embedded in the display panels and/or in the interconnect substrates. A display may have an active area with pixels that includes non-spline pixels in a non-spline display portion located above a straight edge of the display and spline pixel in a spline display portion located above a curved edge of the display.
