Problems solved by technology

[0003] The wiring structure of the touch screen needs to be arranged according to the size of the touch screen. The larger the size of the touch screen, the more touch electrodes are laid on the ITO layer, resulting in a significant increase in the cost of the touch screen
Moreover, since the touch electrodes mostly ad...

Abstract

The invention discloses a wiring structure of a touch screen. The wiring structure of the touch screen comprises a guard plate, an upper ITO (Indium Tin Oxide) layer, a glass plate and a lower ITO layer, wherein the upper ITO layer and the lower ITO layer are distributed at the same side or two sides of the glass plate; each ITO layer is respectively provided with a plurality of touch electrodes; the upper ITO layer is provided with multiple Y touch electrodes; the lower ITO layer is provided with multiple X touch electrodes; the X touch electrodes and the Y touch electrodes are of a hollow rectangular frame shape; and the overlapped parts of the X touch electrodes and the Y touch electrodes are provided with a plurality of suspended blocks in a centrosymmetry mode. By virtue of the mode, the wiring structure disclosed by the invention can be used for realizing the wiring structure requirements of a large-size touch screen by using less touch electrodes, and is higher in linearity.

Description

technical field [0001] The invention relates to a wiring structure, in particular to a wiring structure of a touch screen. Background technique [0002] In recent years, the hot capacitive touch screen on the market uses ITO to complete the touch detection action. The so-called ITO (indium tin oxide) is a key material for the production of liquid crystal displays. At present, it is used in instruments, computers, Electronic watches, game consoles and household appliances have been widely used. The ITO wiring on the capacitive touch screen is generally double-layer. The main principle is: when the user touches the electric field of the human body, the mutual capacitance (also called coupling capacitance) of the sensing unit at the intersection of the surface row or column will change. Finally, the specific position of the touch point can be detected according to the above changes. [0003] The wiring structure of the touch screen needs to be laid out according to the size o...
