Problems solved by technology

[0003] In the double-layer film thinning scheme, the stacked structure of the double-layer electrodes in the capacitive touch screen is mainly compressed, such as sputtering electrode layers on both sides of a very thin film, thereby optimizing the overall capacitive touch screen thickness, but the mutual capacitance between the double-layer electrodes will also change accordingly. How to deploy the patterns of the electrodes on each layer so that the mutual capacitance generated can achieve the expected effect is a relatively important issue.

Abstract

An embodiment of the invention discloses a capacitive touch screen and an electronic device and is applied to the technical field of electronic equipment. Induction electrodes on a drive electrode layer and a receiving electrode layer of the capacitive touch screen are spaced, so that the distance between the receiving electrode layer and the drive electrode layer can be small as far as possible, particularly smaller than 45 micrometers, and the requirements of the touch screen for light weight and thickness are met. Specifically, the area of the induction electrodes on the drive electrode layer and the receiving electrode layer is decreased, the distance between the two electrode layers is decreased moderately to increase mutual capacitance, the mutual capacitance formed between the two electrode layers is finally formed in the measurement range of a detection unit, and the performance of the capacitive touch screen is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a capacitive touch screen and electronic equipment. Background technique [0002] At present, electronic products such as mobile phones, tablet computers and mobile Internet devices (Mobile Internet Device, MID) and other consumer electronic products have a trend of ultra-thinning. For capacitive touch screens, there are mainly the following types in the prior art: Thinning schemes of various methods: single-layer solution (One Glass Solution, OGS) scheme, In-cell, On-cell, thin-layer (Film) single-layer structure scheme and double-layer Film thinning scheme. [0003] In the double-layer film thinning scheme, the stacked structure of the double-layer electrodes in the capacitive touch screen is mainly compressed, such as sputtering electrode layers on both sides of a very thin film, thereby optimizing the overall capacitive touch screen However, the mutual capacitan...
