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: An electronic display may include a first anode configured to carry a red emission signal, a second anode configured to carry a blue emission signal, a third anode configured to carry a green emission signal, and a micro-driver configured to stagger a timing of the red emission signal, the blue emission signal, and the green emission signal based on an emission clock signal to display image content 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: A display may be formed by an array of light-emitting diodes mounted to the surface of a display substrate. The light-emitting diodes may be inorganic light-emitting diodes formed from separate crystalline semiconductor structures. An array of pixel control circuits may be used to control light emission from the light-emitting diodes. Each pixel control circuit may be configured to control one or more respective passive matrices. To control partial pixel cells in the display, a donor pixel control circuit in a partial pixel cell may control the pixels in a receptor partial pixel cell without a pixel control circuit. To mitigate the size of an inactive area of the display, fanout signal lines for the display may be formed in the light-emitting active area of the display. The fanout signal lines may be formed between a row of pixel control circuits and a bottom edge of the light-emitting active area.

Abstract: Circuits, systems, methods, and devices are provided for isolating the first ground domain from the second ground domain while transmitting and receiving data between the two ground domains. The proposed high-voltage ground-isolating level shifter may be formed by AC coupling capacitors and a memory cell. The circuit under the high voltage ground domain may be located in an engineered high-voltage isolation well with a relatively large breakdown voltage.

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.
