Abstract:
1. A method for performing burst refresh of a display device, the method comprising: causing a display device to be driven via video signals that are generated based on pixel data stored in a local memory that is associated with a buffered refresh controller, wherein the local memory includes a local frame buffer; configuring an interface that connects a graphics processing unit (GPU) to the display device and has a data transmission rate that enables the GPU to transmit active pixel data to the display device faster than the refresh rate of the display device; transmitting pixel data associated with a first frame of video to the display device via the interface, wherein the display device stores the pixel data associated with the first frame in the local memory; entering a power-saving state after the pixel data associated with the first frame has been transmitted to the display device; exiting the power-saving state prior to a time when the display device begins to scan out from the local memory pixel data associated with a second frame of video, wherein the first frame of video and the second frame of video comprise all same pixel data and are consecutive frames of video displayed by the display device; and transmitting the pixel data associated with the second frame of video to the display device via the interface.
