Abstract: The present disclosure proposes a plug-in touch display with a pressure sensing function. The touch display includes a capacitive touch screen to sense a touch and a display module includes a display panel having conductive layers which one of the conductive layers is configured to be used as a first capacitive sensing electrode, a backlight module positioned oppositely to the display panel, and a middle frame, configured to support the display panel and the backlight module. A second capacitive sensing electrode is positioned at a side of the middle frame, which is toward the backlight module. A gap exists between the second capacitive sensing electrode and the backlight module. The first capacitive sensing electrode and the second capacitive sensing electrode forms a capacitive sensing structure for sensing a pressure applied on the capacitive touch panel. This structure is compact and easy to produce and thus reduces the manufacturing expenses.

Abstract: A driving method of touch panels is disclosed. The touch panel includes gate lines and data lines intersecting with each other, and at least one switch component arranged at intersections of the gate lines and the data lines, and the switch component connects to the gate line and the data line. During a touch scanning phase, when a touch scanning voltage is applied to a gate line, a gate turn-off voltage of the gate line oscillates together with the touch scanning voltage at the same amplitude and frequency to prevent the switch component from being turned on during the touch scanning phase. In addition, the touch panel and the touch display driven by the driving method are disclosed.
