Abstract: Devices and methods are provided to overdrive or underdrive a display panel to account for display pixel hysteresis due to several frames of pixel history. An electronic device may include an electronic display and processing circuitry. The electronic display includes a number of display pixels. The processing circuitry may generate image data for the display pixels. The processing circuitry may receive a current frame value of the image data targeted for a first display pixel and, based at least in part on the current frame value and a pixel history of the first display pixel—may indicate a gray level for a number of previous frames—generate a compensated value by which to drive the first pixel to overcome pixel hysteresis to reach the desired luminance at an initial response.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To prevent a visible border between the reduced resolution areas of the display and full resolution areas of the display, uniformity compensation circuitry may be used to compensate pixel data. The uniformity compensation circuitry may output compensated pixel data for the display using one or more compensation maps that include compensation factors associated with pixel locations. The uniformity compensation circuitry may also use region-specific gamma look-up tables to apply different gamma curves to pixels in different regions of the display. The uniformity compensation circuitry may also be used to form a transition region between different regions of the display.

Abstract: Systems, methods, and devices for reducing or eliminating image artifacts due to motion are provided. An electronic display may include an electronic display panel having a display pixel, an optical combiner that directs light from the display pixel toward a viewing area, and display driver circuitry. The display driver circuitry may receive image data that defines a total pulse width for one image frame. The display driver circuitry may cause the display pixel to emit light in in multiple pulses totaling to the total pulse width for the display pixel for one image frame.

Abstract: Techniques for implementing and/or operating an electronic device that includes a display panel, which displays an image and includes a first panel section implemented with a lower pixel resolution and a second panel section implemented with a higher pixel resolution, an optical sensor disposed behind the first panel section of the display panel, and image processing circuitry communicatively coupled to the display panel. The image processing circuitry receives source image data corresponding with the image, in which the source image data is indicative of target luminance of a display pixel, determines a pixel resolution surrounding the display pixel, processes the source image based at least in part on the pixel resolution surrounding the display pixel to facilitate determining display image data corresponding with the display pixel, and outputs the display image data to enable the display panel to display the image based on the display image data.

Abstract: There is provided a removable chromatic witness assembly, system, and method to monitor thermal events and impact events on a surface of a composite structure. The removable chromatic witness assembly has a plurality of chromatic witness geometric configurations separately coupled in an arrangement to one or more portions of a polymeric film layer. Each chromatic witness geometric configuration has a plurality of chromatic probes of a same type incorporated into an adhesive material. At least two of the geometric configurations have a different type of chromatic probes with a different sensing capability for thermal events and impact events on the composite structure. The polymeric film layer and the geometric configurations form the removable chromatic witness assembly in a form of a removable chromatic witness applique configured to be removably applied directly and continuously to the surface of the composite structure, and configured to monitor the thermal and impact events.
