Abstract: A video processing system includes a graphics subsystem including a graphics processing unit (GPU) and a frame buffer. The GPU is configured to obtain a physical pixel layout corresponding to a display architecture of an electronic display, wherein the physical pixel layout is characterized by a non-uniform subpixel arrangement; receive image data, including a matrix of logical pixel chroma values; subsample the matrix of logical pixel chroma values according to the physical pixel layout to produce subsampled image data having a subpixel rendered format corresponding to the non-uniform subpixel arrangement; store the subsampled image data in the frame buffer; and enable transfer of the subsampled image data to a display processing unit (DPU) of the electronic display for composition of frames having the non-uniform subpixel arrangement.

Abstract: Embodiments include methods and devices for per layer motion adaptive over-drive strength control for a display panel. Various embodiments may include determining motion information associated with a frame layer, determining an over-drive strength factor for the frame layer based at least in part on the motion information associated with the frame layer, and determining whether the over-drive strength factor is associated with computing a content difference. Various embodiments may include, in response to determining that the over-drive strength factor is associated with computing a content difference, performing fragment shading on the framebuffer object for the frame layer to generate an over-drive compensated framebuffer object for the frame layer based at least in part on the over-drive strength factor, and outputting the over-drive compensated framebuffer object for the frame layer to a default framebuffer for rendering on the display panel.
