Title: DRIVER CIRCUIT
Abstract:
A driver circuit (20) for driving a touch display panel (10) to execute image displaying and touch sensing. The touch display panel (10) comprises a plurality of common electrodes (101). The driver circuit (20) comprises a modulation end (M) and a modulation circuit (21). The modulation circuit (21) is used for generating a modulation signal (MGND). When the modulation circuit (21) outputs the modulation signal (MGND) to the modulation end (M), the driver circuit (20) drives the touch display panel (10) to execute image display refreshing and further drives the common electrodes (101) to execute self-capacitance touch sensing. All signals on the touch display panel (10) are signals synchronously modulated by using the modulation signal (MGND). The driver circuit (20) for driving a touch display panel (10) to execute image displaying and touch sensing can execute touch sensing in a longer period of time, to avoid restriction from an increase in the display resolution.
