Problems solved by technology

[0004] In the prior art, each driving electrode and receiving electrode on the touch screen needs a separate lead wire, and each lead wire needs an interface, that is, a bonding pad (Bonding Pad) to be connected to the external circuit of the touch screen body, which requires a large number of interface, such more lead wires not only make the structure of the touch screen body in the touch screen device cumbersome, but also are not conducive to the improvement of the performance of the touch screen device

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 creative efforts fall within the protection scope of the present invention.

[0028] An embodiment of the present invention provides a touch screen device. The touch screen device may be a mobile phone, a Global Positioning System (Global Positioning System, GPS) device, or a capacitive touch screen device such as a palmtop computer. The structure includes a cover plate, a touch screen body and a display. And stacked in order from the outside to the inside (the part of the touch screen device that the user can see is the outside...

Abstract

An embodiment of the invention discloses a touch screen device and a touch screen thereof and belongs to the technical field of electronic equipment. By means of the touch screen, identical Y-pole electrodes in m-group Y-pole electrodes of each row of induction channels of an induction array are connected, and the connected Y-pole electrodes correspond to one outgoing line, namely, a plurality of electrodes in one row of induction channels share one outgoing line, so that compared with the fact that one outgoing line is led out of each electrode in the prior art, the touch screen device has the advantages that more than half of outgoing lines can be saved, the more induction nodes are, the more saved outgoing lines are, the structure of the touch screen in the touch screen device can be simplified, and the improvement of performances 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, a single layer of indium tin oxide (Indium Tin Oxides, ITO) can Mutual capacitance is used to realize the touch of the touch screen device. [0003] refer to figure 1 Shown is the setting pattern of mutual capacitance on a single layer in the touch screen body of the touch screen device, wherein each column of sensing channels includes a driving electrode and n receiving electrodes, and a driving electrode and a receiving electrode form a mutual capacitance, that is, a sensing node, If there are m driving electrodes, m*n sensing arrays can be formed. The receiving electrodes of each row need to be shorted toget...
