Embodiment 1

[0029] Such as figure 1 As shown, this embodiment provides a touch panel for detecting the magnitude of the touch pressure. The touch panel includes a first substrate 100 and a second substrate 200 opposite to each other, as well as a first touch electrode 1 , a second touch electrode 2 and a plurality of posts 3 . The first touch electrodes 1 are disposed on the first substrate 100 , the pillars 3 are disposed on the second substrate 200 , and there is a certain distance between the pillars 3 and the first substrate 100 . The second touch electrode 2 is arranged on the pillar 3, and the second touch electrode 2 corresponds to the first touch electrode 1 to form a detection capacitor, and the magnitude of the touch pressure is determined according to the capacitance change of the detection capacitor.

[0030] The specific detection principle is: when the touch panel is touched, the distance between the plurality of pillars 3 and the first substrate 100 decreases, and the dist...

Embodiment 2

[0064] This embodiment provides a touch display device, which includes the touch panel in Embodiment 1, so as to detect the magnitude of the touch pressure. At the same time, it can also realize the detection of the touch position, realize three-dimensional touch detection, optimize the touch function of the touch display device, and overcome the problem that the touch function is limited by the size of the display screen.

[0065] The driving method of the above-mentioned touch display device includes:

[0066] Apply an excitation signal to the first touch electrode of the touch panel, and detect the sensing signal on the second touch electrode, and calculate the detection capacitance between the first touch electrode and the second touch electrode according to the sensing signal The change in capacitance of the detection capacitor, and determine the magnitude of the touch pressure according to the change in capacitance of the detection capacitor.

[0067] When the touch pan...

Abstract

The invention relates to the technical field of touch control display, and discloses a touch control panel and a manufacturing method and driving method thereof, and a touch control display device. The touch control panel can detect the pressure; when the touch control panel is applied to the touch control display device, detection of the touch pressure and a touch position can be achieved, three-dimensional touch detection can be achieved, a touch control function of the touch control display device can be optimized, and the problem that the touch control function is limited by the size of the display screen can be solved. In addition, according to the technical scheme of the invention, detection of the environment pressure can be achieved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch panel, a manufacturing method thereof, a driving method, and a touch display device. Background technique [0002] The ease of use and operational versatility of touchscreens coupled with falling prices and steadily increasing yields have made touchscreens an increasingly popular input device. The touch screen can be divided into plug-in type and built-in type. The plug-in type is to assemble the touch panel in front of the display screen, and the touch area covers the visible area of ​​the display screen to realize touch control. The built-in type is to integrate the touch electrodes on the display panel, with or without a protective glass on the outside, and the user can realize the operation by touching the screen with a finger. [0003] Since the capacitive touch screen has the advantages of high sensitivity, long life and multi-touch support, it has be...
