HARDWARE AUXILIARY CHANNEL FOR SYNCHRONOUS BACKLIGHT UPDATE

摘要

Systems, apparatuses, and methods for synchronizing backlight adjustments to frame updates in a display pipeline. A change in the ambient light is detected and as a result, backlight settings are adjusted. To offset a reduction in the backlight, the color intensity in the frames is increased. While the change in ambient light is detected asynchronously, the adjustment to the backlight settings and color intensity is synchronized to a frame update via a virtual channel for the auxiliary channel of the display interface.

1. A system comprising:
one or more display devices; and a display pipeline in communication with the one or more display devices, wherein the display pipeline is configured to:
receive an indication of a change in a measured ambient light level, wherein the indication is received asynchronously to a current frame being displayed on at least one of the one or more display devices; andupdate a display brightness synchronously with a start of a next frame being displayed responsive to receiving the indication, wherein an update to the display brightness of the next frame corresponds to the change in the measured ambient light level.
