  • Publication number: 20240038176
    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: 9947277
    Abstract: Methods and devices for reducing the power consumption of a frame buffer and timing controller of an electronic display are provided. By way of example, a method of operating an electronic display includes receiving image data from a processor of the electronic display, storing the image data to a buffer of the electronic display, reading the image data from the buffer to supply the image data to a column driver of the electronic display, determining whether an amount of image data stored in buffer is less than a threshold, and switching from reading the image data from the buffer to reading the image data directly from the processor when the amount of image data stored in buffer is less than the threshold.

  • Patent number: 9940896
    Abstract: One embodiment of the present disclosure describes an electronic display. The electronic display includes a display driver that write image frames to pixels of the electronic display with a first refresh rate or a second refresh rate, in which the second refresh rate is less than the first refresh rate. Additionally, the electronic display includes a timing controller that receives image frames from an image source, in which one or more of the image frames are configured to be displayed on the display panel to play video content; determines a capture rate of the video content based at least in part on a cadence with which the image frames are received, in which the capture rate describes a rate at which each of the one or more image frames was captured by an image sensor; and instructs the display driver to write the one or more of the image frames at the second refresh when the second refresh rate is an integer multiple of the capture rate.

  • Patent number: 9743036
    Abstract: Systems and methods for controlling operation of an electronic display are provided. One embodiment describes an electronic display, which includes a display driver that writes image frames to pixels of the electronic display with a first refresh rate or a second refresh rate; and a timing controller that receives a plurality of image frames from an image source, in which the plurality of image frames are displayed on the electronic display to play video content; detects a cadence with which the plurality of image frames are received from the image source; and, based at least in part on the cadence of the plurality of image frames, instructs the display driver to write each of the plurality of image frames either as a single image frame at the first refresh rate or an image frame at the first refresh rate followed by a repeat of the image frame at the second refresh rate.
