  • Patent number: 12437731
    Abstract: A graphics processing unit (GPU) of a processing system transmits pixel data for a frame to a display in a compressed burst, so that the pixel data is communicated at a rate that is higher than the rate at which the display scans out the pixel data to refresh the frame at a display panel. By transmitting pixel data for the frame in a compressed burst, the GPU shortens the time spent transmitting the pixel data and extends the time before the next frame of pixel data is to be transmitted. During the extended time before the next frame of pixel data is to be transmitted, the GPU saves power by placing portions of the processing system in a reduced power mode.

  • Publication number: 20250166585
    Abstract: A display system includes a rendering device and a display device having a plurality of individually-controllable illumination regions. The rendering device is to render a frame for display at the display device during a frame period and to determine a brightness representation for each region of a plurality of regions of the frame, each region of the frame corresponding to an illumination region of the display device. The rendering device further is to set, for each illumination region, an illumination configuration to be applied by the display device for the illumination region during at least one of the frame period and a subsequent frame period based on the brightness representation for the corresponding region of the frame, wherein the illumination configuration controls at least one of an illumination level, a duration, and a position of an illumination strobe to be implemented for the corresponding illumination region.

  • Patent number: 11503310
    Abstract: A device includes an encoder, decoder, codec or combination thereof and inline hardware conversion units that are operative to convert stored image data into one of: an HDR/WCG format and an SDR/SCG format during the conversion process. Each of the inline hardware conversion units is operative to perform the conversion process independent of another read operation with the memory that stores the image data to be converted. In one example, an encoding unit is operative to perform a write operation with a memory to store the converted image data after completing the conversion process. In another example, a decoding unit is operative to perform a read operation with the memory to retrieve the image data from the memory before initiating the conversion process. In another example, an encoder/decoder unit is operative to perform at least one of: the read operation and the write operation.

  • Patent number: 11102493
    Abstract: A single source image encoder encodes more than one display stream, such as multiple display streams each for a different display or multiple display streams for the same display, using multiple indexed color history (ICH) buffers. As applied to a DSC encoder, the same DSC encoder is used to encode more than one DSC compliant display stream. Multiple encoded display bitstreams are output as multiple display data streams to a plurality of displays. Such a configuration can significantly reduce the area cost of an integrated circuit that employs an image encoder since additional encoders are eliminated.

  • Publication number: 20200302896
    Abstract: Briefly, methods and apparatus to provide image content to, and display image content on, variable refresh rate displays with reduced input lag. The methods and apparatus allow for image tearing, or the displaying of image content from more than one video frame, when the render rate of a provided video frame falls outside the display refresh rate range of a variable refresh rate display when the display is refreshing with a previous frame (e.g. the display is in active refresh), thus reducing the input lag of the content of the provided video frame. The methods and apparatus may also prevent image tearing when the render rate of provided video frames is within the display refresh rate range of a display.
