Problems solved by technology

[0003] Most of the current touch screens can only detect two-dimensional coordinates, that is, they can only detect the touch position of the finger in the xy direction on the surface of the touch screen, and cannot detect the pressure in the z direction perpendicular to the surface of the touch screen when the finger presses the screen.

Abstract

The invention discloses a touch module and a driving method and display device thereof. A first transparent electrode layer, a transparent and soft medium layer and a second electrode layer are sequentially arranged on the opposite touch side of a touch substrate, wherein the first transparent electrode layer consists of first touch detection electrodes arranged in an array mode and insulated mutually. In a touch detection time period, first touch detection signals are loaded for the first transparent electrode layer and the second electrode layer meanwhile, a touch position is judged by detecting capacitance value change of the first touch detection electrodes to achieve a two-dimensional touch detecting function. In a pressure detecting time period, second touch detection signals are loaded for the first transparent electrode layer or the second electrode layer, the pressure of the pressure in the z direction perpendicular to the surface of a touch screen is detected by detecting the capacitance value change of the first touch detection electrodes to achieve a two-dimensional touch detecting function to achieve a pressure sensing function.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch module, its driving method and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Currently, touch panels can be classified into: Add on Mode Touch Panel, On Cell Touch Panel, and InCell Touch Panel according to their structure. Among them, the plug-in touch screen is produced separately from the touch module and the display screen, and then bonded together to form a display screen with touch function. [0003] Most of the current touch screens can only detect two-dimensional coordinates, that is, they can only detect the touch position of the finger on the surface of the touch screen in the xy direction, and cannot detect the pressure in the z direction perpendicular to the surface of the touch screen when the finger presses the...
