Patent attributes
An input-display device includes a display screen with display pixels, capacitive sensing electrodes for capacitive sensing in a sensing region of the display screen, and a gate driver circuit associated with the display screen. The gate driver circuit superimposes a critical time window on a full-duration gate control pulse of a gate control signal. The critical time window partially overlaps with the full-duration gate control pulse at least at an end of the full-duration gate control pulse. The gate driver circuit further determines that a transient in a sensing waveform of the capacitive sensing occurs in the critical time window superimposed on the full-duration gate control pulse, and based on the determination, shorten the full-duration gate control pulse to obtain a reduced-duration gate control pulse. The gate driver circuit provides the reduced-duration gate control pulse to a pixel circuit of one of the display pixels.
