Abstract: The present disclosure is directed to estimating and modulating peak luminance of the display substantially in real-time to allow very bright pixels to be shown on the electronic display as long as the total electrical energy drawn by the electronic display does not exceed a threshold. The amount of electrical energy that is being drawn by the electronic display may be estimated from the image data by counting the number of rows of pixels that are emitting pulses in discrete bins of time. Because the pulses draw a predictable amount of electrical energy per row per time bin, the amount of electrical energy drawn by the electronic display may be estimated substantially in real time. The image data on the electronic display may therefore be modulated to avoid drawing too much electrical energy from the power source of the electronic device while permitting a high dynamic range.

Abstract: To reduce image artifacts and non-uniformity associated with a display pixel of an electronic display, processing circuity may adjust a luminance value corresponding to a display pixel according to a per-pixel gain mask, a per-pixel anode mask, or both. To further correct for the non-uniformity, the processing circuitry may convert the luminance value to a digital code based on a curve associated with an anode on which the display pixel is located.

Abstract: Electronic devices, displays, and methods are provided for operating an electronic display in coexistence with sensors that could be adversely impacted by the operation of the electronic display. An electronic device may include an electronic display and a sensor. The electronic display may display image content by light emission during an emission period and periodically enter a quiet period in which the light emission of the electronic display is turned off. The sensor may perform sensing operations during the quiet period without interference from the operation of the electronic display.

Abstract: Electronic displays and electronic devices including such electronic displays and antennas are provided for improved transmission of signals through circuitry of the electronic display. The electronic display may include multiple power supply tiles that are separated with non-conductive gaps to reduce circulation of eddy currents induced by the transmission signals. Moreover, voltage supply routing paths within the power supply tiles may be grouped to provide non-conductive gaps within the power supply tiles. Accordingly, the antenna may provide the transmission signals through the electronic display with improved efficiency based on reducing surface currents (e.g., eddy currents) on the electronic display.

Abstract: Electronic devices, displays, and methods are provided for performing row shuffling to reduce an appearance of image artifacts during eye movements such as saccades. An electronic display may include a number of rows of display pixels and driving circuitry to drive the rows of pixels. The driving circuitry may spatially shuffle or temporally shuffle, or both spatially and temporally shuffle, a row order of driving the rows of display pixels.

Abstract: An electronic device may include an electronic display including display pixels to display an image based on compensated image data. As image data is written to a pixel in the row of pixels, capacitive coupling at a driver may lead to distortion on the driver. In particular, the capacitive coupling may cause distortion at a storage capacitor, which may lead to current droop at the pixel. The current droop may be reduced or eliminated in each pixel by performing pixel compensation. The pattern of the pixel compensation may be selected such that, over a number of subframes, an average amount of light is the same or similar to what would be emitted had pixel compensation been performed on each pixel in each subframe.
