Abstract: An example processing system for a display device includes driver circuitry and a control circuit. The driver circuitry is coupled to a plurality of source line nodes in the display device, each source line node of the plurality of source line nodes coupled to a plurality of subpixel columns through a demultiplexer having a plurality of switches. The control circuit is coupled to each demultiplexer. The control circuit is configured to operate each demultiplexer in a first mode by successively activating the respective plurality of switches, and in a second mode by concurrently activating the respective plurality of switches.

Abstract: Embodiments include a method (as well as an input device and processing system) that includes driving a display signal onto at least one of a plurality of display electrodes for updating a display, and driving an input sensing signal onto at least one of a plurality of sensor electrodes, where driving the input sensing and driving the display signal at least partially overlap in time. The method further includes receiving, using a coupling electrode disposed proximate to the at least one display electrode, a coupling signal that represents an effect of a signal on at least one of the display electrodes, on a signal on at least one of the sensor electrodes, acquiring resulting signals with at least one of the sensor electrodes, and adjusting the resulting signals based on the coupling signal.

Abstract: Embodiments described herein include a display device having a capacitive sensing device, a processing system and a method for providing an adaptive low-power mode. In one embodiment, the method includes generating a reference voltage with one or more reference voltage generators while a display device is in a grayscale mode. The method also includes driving subpixels in the grayscale mode with the reference voltage. The method further includes shutting down the one or more reference voltage generators and driving subpixels in a low power, binary mode with a VCOM voltage based on positive and negative supply rails.
