Single-layer ITO (indium tin oxide) wiring structure

Abstract

The invention relates to a single-layer ITO (indium tin oxide) wiring structure. A plurality of electrode blocks are disposed on a single ITO layer and respectively arrayed in a staggered manner to form a plurality of longitudinal rows and a plurality of longitudinal columns, an upper rectangular wave row and a lower rectangular wave row with equal amplitudes encircle to form each electrode block, the directions of the upper rectangular wave row and the lower rectangular wave row of each electrode block are opposite, gaps are formed between each upper rectangular wave row and the corresponding lower rectangular wave row, and the length of each gap is identical to that of the crest of each upper rectangular wave row and the length of the trough of each lower rectangular wave row. The single-layer ITO wiring structure is simple, and capacitance and signal strength during contact can be guaranteed, so that the single-layer ITO wiring structure is more stable when used for touch detection. In addition, the wiring structure is better in scribing effect as compared with a traditional wiring structure.

Description

technical field [0001] The invention relates to an ITO wiring structure, in particular to a single-layer ITO wiring structure. Background technique [0002] The so-called ITO (indium tin oxide) is a key material used in the production of liquid crystal displays. At present, it is widely used in the fields of instrumentation, computers, electronic watches, game consoles and household appliances. In recent years, the hot capacitive touch screen on the market also uses ITO to complete the touch detection action, and the ITO wiring on the capacitive touch screen is generally double-layered. The main principle is: using the electric field of the human body, when the user touches, the surface moves Or the mutual capacitance (also called coupling capacitance) of the sensing unit at the intersection of columns will change, and the specific position of the touch point can be finally detected according to the above change. [0003] Because ITO itself is more expensive, and the proces...

Problems solved by technology

For this structure, since a group of electrode groups composed of two symmetrical triangles are respectively arranged on the ITO layer, there is a certain limit to the size of the touch screen. With the gradual decrease of the angle of the triangle, The position of touch objects such as fingers cannot be quickly resolved, so that the specific position coordinates of touch points cannot be accurately judged; moreover, the layout of this structure also has unstable touch detection and large power noise interference , The problem of poor line drawing effect

[0004] Therefore, it is necessary to provide users with a wiring structure that can improve the detection instability of the traditional single-layer ITO wiring structure and improve the electrode sensing capability.
