Abstract
The present invention discloses a liquid-crystal display screen with touch-control function and a manufacturing method thereof and an electronic apparatus. The liquid-crystal display screen includes a first sensing electrode and a second sensing electrode, which are included in a common electrode in display electrodes of the liquid-crystal display screen, and are connected to a touch detection unit. Furthermore, the touch detection unit and a display control unit operate in a timesharing manner. In this way, in the touch-control display screen, the common electrode may also be used as an electrode for detecting a touch on the touch-control display screen, and the structure of the display screen is simplified. Moreover, the touch-control display screen has a better light transmittance and the detecting for the touch and the control for the display may not interact with each other.
