摘要： A display driver includes a driver circuit and a sensing controller. The driver circuit is configured to drive a display panel according to display information. The display panel defines a sensing region. The sensing controller interface circuit is configured to transmit an output vertical sync signal to a proximity sensing controller. The proximity sensing controller is configured to generate positional information of an input object based at least in part on a resulting signal received from a sensor electrode disposed in the sensing region. The output vertical sync signal comprises encoding the display information in the output vertical sync signal.

摘要： Driving a display of an input-display device includes generating, during a first display frame, a first touch sensing waveform to be applied to a touch screen of the display, and generating, during a second display frame, a second touch sensing waveform to be applied to the touch screen. The first touch sensing waveform generates on the display a first touch-to-display noise pattern of touch-to-display noise artifacts. The second touch sensing waveform generates on the display a second touch-to-display noise pattern of touch-to-display noise artifacts. The second touch-to-display noise pattern mitigates the first touch-to-display noise pattern.

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 display controller includes a touch sensing controller configured to drive sensing electrodes with a touch sensing waveform that includes multiple modulations. The touch sensing controller is further configured to halt driving the plurality of sensing electrodes when a number of the modulations satisfies a selected sub-burst size. The touch sensing waveform is synchronized to an instance of a horizontal sync signal.
