Touch screen device and touch screen body thereof

Abstract

An embodiment of the invention discloses a touch screen device and a touch screen body thereof, and belongs to the technical field of electronic equipment. Mutual capacitances arranged in an array are arranged on the touch screen body of the touch screen device, and the mutual capacitance on each node is composed of an X pole electrode and a Y pole electrode which are heteropolar; each row in the array comprises m X pole electrodes and n Y pole electrodes, wherein the n and the m are natural numbers; the m X pole electrodes are divided into a plurality of groups, each group of electrodes is connected outside the touch screen body respectively through outgoing lines, wherein at least two groups of electrodes comprise at least two X pole electrodes which are connected adjacently; the n Y pole electrodes are connected outside the touch screen body respectively through outgoing lines; and the X pole electrodes connected adjacently form mutual capacitances with different Y pole electrodes respectively. Only one outgoing line is led out for one group of X pole electrode connected adjacently in each row of mutual capacitances, so that the amount of the outgoing lines can be reduced, the structure of the touch screen body of the touch screen device is simplified, and improvement of the touch performance of the touch screen device is facilitated.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a touch screen device and a touch screen body thereof. Background technique [0002] With the continuous development of touch screens, capacitive touch screens are more and more widely used in terminal equipment. In existing capacitive touch screen devices, it can be achieved by a single layer of indium tin oxide (ITO) mutual capacitance set on the touch screen body. Multi-touch for touchscreen devices. [0003] refer to figure 1 Shown is the arrangement pattern of mutual capacitance on a single layer in a touch screen device, wherein each column includes a Y pole electrode and a plurality of X pole electrodes (such as figure 1 The electrodes of the X poles in a to f), and a Y pole electrode and an X pole electrode form a mutual capacitance, and each X pole and Y pole electrode needs to be drawn out of the touch screen through a lead wire, and connected to the touc...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that in the design of the single-layer mutual capacitance of the existing touch screen equipment, each electrode needs to be led out of the body of the touch screen through a lead wire. Such a large number of lead wires not only makes the structure of the touch screen body in the touch screen device cumbersome, but also is not conducive to the improvement of the performance of the touch screen device.
