    Abstract: A display driver circuit comprises first circuitry to generate a touch drive signal, and second circuitry to provide the touch drive signal to touch sense electrodes of the display device and a touch data signal to data lines of the display device during a touch period and to provide display data signals to data lines of the display device during a display period. A touch gate signal is provided to gate lines of the display device during the touch period. The touch drive signal, the touch data signal, and the touch gate signal mimic a reference waveform, but amplitudes of one or more of the touch drive signal, the touch data signal, and the touch gate signal are overdriven by their respective overdrive amplitude with respect to the reference waveform during their respective overdrive duration.
