Abstract: Often when there is a glare on a display screen the user may be able to mitigate the glare by tilting or otherwise moving the screen or changing their viewing position. However, when driving a car there are limited options for overcoming glares on the dashboard, especially when you are driving for a long distance in the same direction. Embodiments are directed to eliminating such glare. Other embodiments are related to mixed reality (MR) and filling in occluded areas.

Abstract: The present disclosure is directed to systems and methods of maintaining source device to sink device synchronization in systems in which the source device enters a Panel Self-Refresh (PSR/PSR2) mode and the sink device enables adaptive synchronization with the source device. To maintain synchronization, in some instances the source device and the sink device may maintain synchronization contemporaneous with at least a portion of the PSR/PSR2 operating mode. To maintain synchronization, in some instances, a high-bandwidth communications link may be maintained between the source device and the sink device. In some instances, synchronization between the source device and the sink device may be interrupted upon the source device entering the PSR/PSR2 operating mode and may be re-established upon the source device exiting the PSR/PSR2 operating mode.

Abstract: Technology for a display source controller is described. The display source controller can receive display pixel data from a display source. The display source controller can convert the display pixel data to display symbol data that includes a plurality of 32-bit double words (DWords). The display source controller can divide the display symbol data that includes the plurality of 32-bit DWords for a number of unidirectional serial data channels. The display source controller can process, for each unidirectional serial data channel, the display symbol data at a 32-bit DWord granularity level. The display source controller can send the display symbol data for each of the unidirectional serial data channels over a physical serial link to a display panel.

Disclosed examples also up-sample the second image data based on first metadata to generate up-sampled second image data, the up-sampled second image data to have the first resolution, and combine the first image data and the up-sampled second image data based on second metadata. Disclosed examples further perform, based on third metadata, a combination of at least two different filter operations on an overlap region including a portion of the first image data and a portion of the up-sampled second image data to generate the foveated image frame, the third metadata to specify a width in pixels of the overlap region.
