Abstract: A display processing device includes a display device interface and a processing unit. The processing is configured to transition at least a first component of the display processing system into a low-power state in response to an active region of a first video frame of a plurality of video frames having completed. A second component of the display processing device is configured to maintain a temporal count value corresponding to a current frame line of the plurality of video frames, and further to generate a first signal in response to the temporal count value corresponding to a first trigger value. The first signal causes the at least first component to transition out of the low-power state.
