  • Publication number: 20240233604
    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.

  • 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.

  • Publication number: 20240203335
    Abstract: Systems and methods described herein may utilize a non-linear scaling relationship to scale brightness of selective portions of the display in a manner that reduces or eliminates perceivable banding effects. By non-linearly controlling changes in brightness of the display, a viewer may perceive a more uniform, linear dimming towards the relatively dimmer region without perceiving banding, leading to improved user experience when viewing the electronic display.

  • Publication number: 20240203332
    Abstract: In a display characterized by regions with different pixel responses due, for example, to local pixel density variation, voltage-to-luminance matching may be non-universal. Therefore, in order to avoid visual artifacts that may hinder a desired visualization of displayed content, it may be advantageous to compensate the different gamma responses. In some cases, such as with electronic devices having a single pixel density across the display, optical calibration may be performed to determine voltage-to-luminance matching. However, in electronic devices with local pixel density variations, it may be disadvantageous to perform optical calibrations for each region with a different pixel density. Instead of using two distinct gamma curves which may include dedicated optical calibration, a global nonlinear scaler (GNLS) compensation may be applied.

  • Publication number: 20240169903
    Abstract: An electronic device may include an electronic display having a gate-on-array (GOA) that generates gate signals in response to an activation signal, pixels that activate in response to a combination of the gate signals and data signals indicative of image data, and sensing circuitry. The sensing circuitry may measure a characteristic response of a gate signal a characteristic response of one or more pixels, or both and compare the characteristic responses to baselines. The electronic device may also include compensation circuitry that applies a compensation to the activation signal and/or to the image data based on the comparisons between the characteristic responses and the baselines.

  • Publication number: 20240038154
    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: 11882858
    Abstract: A skin whitening composition includes ?-mangostin or a cosmetically acceptable salt thereof as an effective ingredient. ?-Mangostin represented by Chemical Formula 1 suppresses the expression of tyrosinase and TRP-1 (tyrosinase-related protein-1) and induces autophagy of a melasosome. As such, it was confirmed that the ?-mangostin not only suppresses melanin production but also exhibits the effect of removing previously formed melanin. Accordingly, the ?-mangostin can be advantageously used as a functional material for skin whitening and skin lightening.

  • Publication number: 20240013692
    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.
