Abstract
Disclosed are systems, methods, and non-transitory computer-readable media for reducing latency in augmented reality displays. A display controller receives, from a GPU, a stream of image pixels of a frame of virtual content to be presented on a display of a display device. The stream of image pixels is received via a high-speed bulk interface that transfers data at least as fast as can be consumed by the display. As the stream of image pixel is received, the display controller converts each respective image pixel from a data format used to transmit the stream of image pixels via the high-speed bulk interface to a data format that is compatible for display by the display. Each converted image pixel is stored in a pixel cell of the display, after which the frame is presented on the display.
