  • Temporarily increased refresh rate for a display panel in low power mode
    Patent number: 10354579
    Abstract: In one example, an apparatus comprises a display panel having a first active mode with a first refresh rate and at least one of a first bit depth or a first brightness, and further having a second active mode with a second refresh rate and at least one of a second bit depth or a second brightness, the second refresh rate being lower than the first refresh rate, the second bit depth being lower than the first bit depth, and the second brightness being lower than the first brightness. The apparatus further comprises a controller. In response to receiving an image update request while the display panel is in the second active mode, the controller is configured to otherwise keep the display panel in the second active mode but switch the display panel to an intermediate refresh rate higher than the second refresh rate until completion of the image update request.
