  • Patent number: 12039120
    Abstract: A processing system includes sensor circuitry and processing circuitry. The sensor circuitry is configured to, using the sensor electrodes, obtain capacitive measurements of a sensing region, and obtain a resistance measurement of the sensing region. The processing circuitry is coupled to the sensor circuitry. The processing circuitry is configured to determine a location of an input object using the capacitive measurements of the sensing region and determine a force value based on the resistance measurement and the location of the input object. Determining the force value mitigates a temperature variation of the sensing region affecting the resistance measurement. The processing circuitry is further configured to report the force value.

  • Patent number: 11972713
    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: In a display device having a non-rectangular display unit, occurrence of a difference in luminance between a region with a high load and a region with a low load is suppressed. A region inside the display unit is segmented into a high-load region with a high load on horizontal scanning lines (an initialization control line and a write control line) and a low-load region with a low load on horizontal scanning lines. An initialization control line and a write control line that are disposed in the high-load region are driven by a discharge driver and a scan driver, respectively. An initialization control line and a write control line that are disposed in the low-load region both are driven by, for example, the discharge driver.
