摘要： In general, in one aspect, one or more embodiments relate to an input device that includes a proximity sensing panel including sensor electrodes, and a proximity sensing circuit. The proximity sensing circuit is configured to determine that an image refresh rate to an equal or lower frequency than a beacon signal rate. The input-display device is configured to align transmitting a beacon signal on proximity sensing panel to during non-refresh period of a display or perform an additional image refresh frame on the display panel immediately before a next Vsync signal and a corresponding non-refresh period.

摘要： In general, in one aspect, one or more embodiments relate to an input device that includes a proximity sensing panel including sensor electrodes, and a proximity sensing circuit. The proximity sensing circuit configured to receive an indication of a transition from a first image refresh rate to a second image refresh rate, wherein the first image refresh rate is greater than a beacon signal rate and the second image refresh rate is equal to or lower than the beacon signal rate. The proximity sensing panel is also configured to align transmitting a beacon signal on the proximity sensing panel to a non-refresh period corresponding to the second refresh rate.

摘要： An input-display device includes a display panel, sensor electrodes, and a display driver. The display panel includes source lines. The sensor electrodes are capacitively coupled to the source lines. The display driver is configured to receive image data. The display driver is further configured to process the image data in response to a detection of a horizontal stripe pattern in an image corresponding to the image data. The display driver is further configured to drive the source lines based at least in part on the processed image data.

摘要： A processing system includes a timing controller and source driver circuitry. The timing controller is configured to stop scanning of a plurality of gate lines of a display panel in response to a detection of a communication failure between the processing system and a controller. The source driver circuitry is configured to update a plurality of display elements of the display panel to cause a black display in response to expiration of a time limit after the detection of the communication failure. The timing controller may be further configured to resume the scanning of the plurality of gate lines in response to the expiration of the time limit.
