Abstract

The invention is applied to the field of touch control technologies and provides a single-layer mutual capacitance touch screen, a touch screen device and equipment. The touch screen comprises a binding bonding pad and induction electrode units distributed side by side, wherein the binding bonding pad is connected with a touch detection circuit; each induction electrode unit comprises a first electrode, a first electrode set and a second electrode set, each first or second electrode set comprises a plurality of second electrodes, the first electrode and the second electrodes of each induction electrode unit are coupled to form induction nodes, the first electrodes are connected through first lead wires, and the second electrodes are connected through second lead wires; each first electrode set corresponds to the corresponding first electrode, and each second electrode set corresponds to another first electrode; the second electrodes in the two electrode sets of each induction electrode unit are distributed in a mirror symmetry mode, and each second electrode of each electrode set is connected with the binding bonding pad through a second lead wire. Through arrangement and combination of drive electrodes and reception electrodes, the number of leads and the number of PADs to be bound are reduced, the binding yield is increased, linearity, precision and reliability of binding are improved, and the area and cost of an FPC are reduced.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a single-layer mutual capacitance touch screen, a touch screen device, and equipment. Background technique [0002] At present, in a mutual capacitance touch screen composed of a single layer of electrode patterns, each electrode pattern is connected to a bonding pad (PAD) through a separate lead, so that the mutual capacitance touch screen not only needs more bonding pads , and more lead wires are required, and the more lead wires occupy more effective touch areas of the mutual capacitance touch screen, which in turn leads to a decrease in the linearity and touch sensing accuracy of the mutual capacitance touch screen. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a single-layer mutual capacitance touch screen, aiming at solving the problems of the current single-layer mutual capacitance touch screen with too many lead ...
