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.

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.

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.

Abstract: Systems and methods for programming an electronic display in a double-row manner are provided. A system may include processing circuitry that generates image data and an electronic display that programs multiple rows of display pixels with different pixel data of the image data at the same time. This may allow double-row interlaced driving to reduce or eliminate image artifacts due to intra-frame pauses.

Abstract: An electronic display may include a touch sensing system configured to perform touch sensing in an active area of the electronic display and display driver circuitry configured to program display pixels of the active area to emit light. The electronic display may also include the active area. The active area may include a first portion and a second portion that are at least partially electrically separated. The display driver circuitry may program the display pixels in the first portion while the touch sensing circuitry may perform touch sensing in the second portion.

Abstract: This disclosure is directed towards systems and methods of power saving in electronic displays based on changing clock signal frequencies supplied to the gate-in-panel (GIP) circuitry during extended blanking modes of the electronic display. The display driver circuitry of the display may reduce and/or halt clock signal frequencies sent to GIP circuitry in the display, to reduce power output during extended blanking modes of the electronic display.

Abstract: Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.

Abstract: Embodiments presented herein relate to reducing visual artifacts on an electronic display caused by an intra-frame pause. To do so, the intra-frame pause may be divided into smaller intra-frame pause segments. The intra-frame pause segments may be applied to the display during different image frames and/or at different locations on the electronic display. For example, each intra-frame pause segment may be applied to a different location on the electronic display. In some embodiments, multiple intra-frame pause segments may be applied during a single image frame. In some embodiments, the intra-frame pause segments may be applied to various image frames and at various location on the electronic display according to a pattern. To reduce band flickering that may be caused by the different locations of the intra-frame pause segments, an emission duty of one or more rows of pixels of the display may be adjusted.

Abstract: Electronic devices and methods for compensating for aging or other effects in a display during a non-transmitting state (off state) of the display. Sensing may include emissive element sensing of the display and/or thin film transistor sensing of the display. Compensating for the effects may preserve or increase a uniformity of transmission of the display.
