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 first ground terminal (201) and a modulation circuit (21). The modulation circuit (21) is connected to the first ground terminal (201) and used for generating a modulation signal (MGND). When the modulation circuit (21) outputs the modulation signal (MGND) to the first ground terminal (201), the driver circuit (20) drives the touch display panel (10) to execute image display refreshing and further drives the common electrodes (101) to execute touch sensing. All signals on the touch display panel (10) are signals synchronously modulated by using the modulation signal (MGND).
