Abstract

The invention provides a touch screen and electronic equipment. Specifically, the touch screen includes: a protective cover; a display module, the display module is arranged under the protective cover; and a pressure sensing structure, the pressure sensing structure includes a first pressure sensing layer and a second pressure sensing layer. In the pressure sensing layer, the first pressure sensing layer and the second pressure sensing layer are electrically connected, and in the pressure sensing structure, the initial capacitance of the pressure sensing capacitor is not greater than 50% of the upper limit of the IC detection capacitance. By designing the distance and area between the first pressure-sensing layer and the second pressure-sensing layer, the initial capacitance value of the pressure-sensing capacitor formed by it has a certain proportional relationship with the upper limit of the IC detection capacitance value, thereby preventing pressure sensing , since the pressure-sensing capacitance becomes larger after pressing, the pressure-sensing capacitance after pressing exceeds the upper limit of IC detection and signal overflow occurs.

Description

Technical field [0001] The present invention relates to the field of electronics, in particular to touch screens and electronic devices. Background technique [0002] Because of the advantages of easy operation, intuitiveness and flexibility, touch screens have become the main human-computer interaction means for personal mobile communication devices and integrated information terminals such as tablet computers, smart phones, and super laptops. According to different touch principles, touch screens can be divided into four main types: resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave (SAW) touch screens. Among them, the capacitive touch screen has multi-touch function, fast response time, long service life and high light transmittance, and the user experience is superior. At the same time, with the gradual maturity of the process, the yield rate has been significantly improved, and the price of capacitive screens is decreasing. A...
