Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Dividing the common electrode layer into a plurality of electrode blocks with sawtooth structures on the edges, and making the sawtooths between adjacent electrode blocks nested with each other can improve the touch detection accuracy. When performing a touch operation, when touching the central area of ​​a common electrode block, only the touched electrode block will generate a detection signal; when touching a jagged area where a certain ...

Abstract

A touch screen and a touch display electronic device are provided. The touch screen includes a substrate; and an auxiliary electrode layer, a common electrode layer and a wire layer arranged on a same side of the substrate. The common electrode layer and the wire layer are arranged opposite to each other in a direction perpendicular to the substrate. The common electrode layer includes multiple common electrode blocks having a same shape and a same area; each of the common electrode blocks includes a central electrode and sawtooth-shaped electrodes connected to the central electrode; and the sawtooth-shaped electrodes of any two adjacent common electrode blocks are fitted with each other. The wire layer includes multiple first wires connected to the multiple common electrode blocks. The auxiliary electrode layer includes multiple auxiliary electrode blocks. The sawtooth-shaped electrodes adjacent to edges of the substrate are fitted with the auxiliary electrode blocks.

Description

technical field [0001] The present invention relates to the technical field of touch devices, and more specifically, to a touch screen and touch display electronic equipment. Background technique [0002] With the continuous development of science and technology, more and more touch electronic devices are used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable and important tool for people today. tool. [0003] The embedded self-capacitance touch screen has the advantages of high touch accuracy and high signal-to-noise ratio, and has become a commonly used touch screen for touch electronic devices. refer to figure 1 , figure 1 It is a structural schematic diagram of a common self-capacitance touch screen in the prior art, and the self-capacitance touch screen includes: a common electrode layer and a wiring layer arranged opposite to each other. The common electrode layer and the wiring layer ar...
