  • Publication number: 20260065824
    Abstract: An electronic device may include an electronic display to display frames of image data and processing circuitry to determine a display strain transition event of the electronic display and change a refresh rate of the electronic display based on the determination of the display strain transition event. The electronic device may temporarily increase the refresh rate based on determining that the display strain transition event includes folding or unfolding the electronic display. The electronic device may sequence down the refresh rate to a lower refresh rate after a period of time. As such, perceivable image artifacts in displayed image content caused by folding or unfolding the electronic display may be reduced or eliminated.

  • Patent number: 12499806
    Abstract: An electronic device may include an electronic display having multiple display pixels that display an image based on dithered image data. The electronic device may also include image processing circuitry that generates the dithered image data based on input image data and a threshold gray level that is greater than one. Generating the dithered image data may include replacing each gray level of the input image data that is less than the threshold gray level with either a zero gray level or the threshold gray level according to a dither pattern.

  • Publication number: 20250299624
    Abstract: Electronic devices, displays, and methods are provided for compensating image data to account for self-coupling by display pixels on a shared data line. An electronic display may include an electronic display panel with lines and columns of display pixels. Each column of display pixels may be coupled to a respective data line. Display driver circuitry may adjust image data associated with the display pixels to account for coupling between the display pixels and the respective data lines.

  • Publication number: 20250292718
    Abstract: Display pixels of an electronic display may exhibit front-of-screen distortions when high spatial frequency image data is applied on the electronic display panel. The high spatial frequency may generate voltage ripple on a storage capacitor of pixel driving circuitry, causing mismatch between luminance of a first subpixel on an odd-numbered row and a corresponding subpixel on an even-numbered row. This odd-even row mismatch may be compensated via mismatch compensation circuitry. The mismatch compensation circuitry may include an odd subpixel compensation LUT and an even subpixel compensation LUT. The odd subpixel compensation LUT may output odd subpixel compensation values and the even subpixel compensation LUT may output even subpixel compensation values. The multiplexer may combine the odd subpixel compensation values and the even subpixel compensation values with input image data to generate compensated subpixel data, which may reduce or eliminate the odd-even row mismatch.

  • Patent number: 12394345
    Abstract: To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.

  • Patent number: 12136387
    Abstract: An electronic device may include processing circuitry configured to generate a first frame of image content and a second frame of image content. The second frame of image content is different from the first frame of image content. The electronic device may also include a display configured to display the first frame of image content at a first refresh rate. In response to receiving the second frame of image content, the electronic device may initially increase the refresh rate before tapering back to the first refresh rate while displaying the second frame of image content.

  • Patent number: 12020648
    Abstract: Systems and methods are described here to compensate for crosstalk (e.g., coupling distortions) that may be caused by a fanout overlaid or otherwise affecting signals transmitted within an active area of an electronic display. The systems and methods may be based on buffered previous image data. Technical effects associated with compensating for the crosstalk may include improved display of image frames since some image artifacts are mitigated and/or made unperceivable or eliminated.

  • Patent number: 11911128
    Abstract: A mote includes an optical receiver that wirelessly receives a power and data signal in form of NIR light energy within a patient and converts the NIR light energy to an electrical signal having a supply voltage. A control module supplies the supply voltage to power devices of the mote. A clock generation circuit locks onto a target clock frequency based on the power and data signal and generates clock signals. A data recovery circuit sets parameters of one of the devices based on the power and data signal and a first clock signal. An amplifier amplifies a neuron signal detected via an electrode inserted in tissue of the patient. A chip identifier module, based on a second clock signal, generates a recorded data signal based on a mote chip identifier and the neuron signal. A driver transmits the recorded data signal via a LED or a RF transmitter.
