Abstract

The present invention proposes a touch screen and an electronic device. The touch screen comprises: a first pressure-sensitive layer, wherein the first pressure-sensitive layer is arranged on an uppersurface or a lower surface of an upper polarizer, the upper surface or the lower surface of a lower polarizer, or the upper surface of a colorized optical filter; and a second pressure-sensitive layer, wherein the second pressure-sensitive layer is electrically connected with the first pressure-sensitive layer, and the second pressure-sensitive layer and the first pressure-sensitive layer form the pressure-sensitive capacitance. Thus, according to the electronic device provided by the present invention, the integration level of a display module can be improved, and the first pressure-sensitive layer can be set by using the intrinsic structure inside the display module in a facilitated manner, and the thickness of the touch screen can be reduced in a facilitated manner; and the touch screen provided by the present invention has advantages of a simple preparation process, good flatness, sensitive induction and the like.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a touch screen and electronic equipment. Background technique [0002] Due to its advantages of ease of operation, intuition, and flexibility, the touch screen has become the main means of human-computer interaction for personal mobile communication devices and comprehensive information terminals, such as tablet computers, smart phones, and super notebook computers. Touch screens can be divided into four main types according to different touch principles: resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave (SAW) touch screens. Among them, the capacitive touch screen has the function of multi-touch, fast response time, long service life and high light transmittance, and the user experience is superior. , has become the main technology used in touch interaction of small and medium-sized information terminals. The current capacitive touch ...
