Title: TOUCH DISPLAY UNIT AND ELECTRONIC DEVICE
Abstract:
A touch display unit (5) and an electronic device (200). The touch display unit (5) comprises a touch display panel (10), a control chip (51), and a driver chip (53). The touch display panel (10) comprises a plurality of common electrodes (101). The driver chip (53) is used for driving the touch display panel (10) to execute image displaying, and is further used for driving the plurality of common electrodes (101) to execute touch sensing. The driver chip (53) comprises a modulation end. The control chip (51) is used for generating a modulation signal. When the control chip (51) outputs the modulation signal to the modulation end of the driver chip (53), the driver chip (53) drives the touch display panel (10) to simultaneously execute image display refreshing and touch sensing. Signals on the touch display panel (10) all increase as the modulation signal increases, and decrease as the modulation signal decreases. The electronic device (200) comprises the touch display unit (5).
