  • 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.

    Abstract: A system that can determine states of human activity and transitions between those states using wireless signal data. A machine learning model such as a Hidden Markov Model (HMM) may be trained to determine transitions between states of human activity (e.g., static, slow movement, fast movement) using information from wireless signal data, such as channel state information gathered from Wi-Fi signal beacons. Depending on the state of the human activity the system may then cause certain commands to be executed corresponding to the human activity such as turning on a certain configuration of lights, playing certain music, or the like.
