Abstract

The invention provides a pressure touch screen and a display device, and relates to the technical field of display device, and solves the problems of high requirement of assembling precision, the derived difficulties of assembling operation and low assembling quality of the display device containing a pressure touch screen. The screen comprises a touch layer, the light receiving side of the touch layer is provided with a pressure sensing detection device. The pressure sensing detection device comprises a first electrode layer, a second electrode layer and a flexible separation cushion layer. The first electrode layer is connected with connected with the touch screen adhesively. The first electrode layer and the second electrode layer are in contraposition. The flexible cushion payer is located between the first electrode layer and the second electrode layer. The hardness of the first electrode layer is smaller than the hardness of the second electrode layer. The touch screen can be applied to display device to enhance the assembly passing rate of the display devices.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a pressure touch screen and a display device. Background technique [0002] At present, the touch screen has become the main human-computer interaction means of the display device with touch function due to its advantages of easy operation, intuition and flexibility. Touch screens can be classified into four main types according to different touch principles: resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave (ASW, Surface Acoustic Wave) touch screens. Among them, the capacitive touch screen has a multi-touch function, fast response time, long service life, and high transmittance. Therefore, the capacitive touch screen with superior user experience has gradually become the main technology for touch interaction. [0003] There are usually two ways for capacitive pressure-sensing touch screens to detect touch pressur...
