  • Publication number: 20240012515
    Abstract: Touch sensitive display technologies (e.g., integrated touch-display pixel-based systems) are evolving to contain more analog and digital circuits inside the panel itself instead of the traditionally simple thin-film transistors. This improves the display characteristics but makes those circuits more vulnerable to the impact of external ESD strikes, which can degrade the user experience. This disclosure describes a series of circuits and techniques to mitigate the impact of these discharges on front of screen artifacts and potential false touches. These circuits and techniques may include: performing configuration-only panel updates independently of the image refresh rate, improving the in-panel memory circuits to make them resistant to unexpected pin toggles via disabling of a write path in response to a read clock, implementing a pin corruption detector and implementing a supply injection detector.

  • Publication number: 20240005833
    Abstract: A control circuit adjusts a value of a source supply voltage VSSEL provided to a display area in an electronic display. The control circuit also adjusts a voltage Vreset applied to the display area to cause the display area to emit light more uniformly under various ambient conditions (e.g., temperature) surrounding the display area. Dynamically changing Vreset is employed to make anode charging dynamics independent of temperature. The control circuit adjusts the source supply voltage VSSEL and the voltage Vreset together to compensate display pixel hysteresis effects and display artifacts caused by temperature changes and brightness changes of the display area and collectively produce images. Dynamically tuning the Vreset and the VSSEL voltages also saves power and improves gray level accuracy for the electronic display.

  • Publication number: 20240005850
    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.
