Title: TOUCH DISPLAY UNIT AND ELECTRONIC DEVICE
Abstract:
A touch display unit (1) and an electronic device (100). The touch display unit (1) comprises a touch display panel (10) and a driving circuit (20). The touch display panel (10) comprises multiple pixel electrodes (103) and multiple common electrodes (101). The driving circuit (20) drives, by providing first gray-scale voltage (Vd1) for the pixel electrodes (103) and providing first common voltage (Vc1) for the multiple common electrodes (101), the touch display panel (10) to perform image display refreshing, and at the same time, further drives the common electrodes (101) to perform touch sensing, wherein the first gray-scale voltage (Vd1) and the first common voltage (Vc1) are both signals modulated by a modulation signal (MGND). The electronic device (100) comprises the touch display unit (1).
