Abstract

The invention discloses a double-layer ITO (indium tin oxide) wire arrangement structure. A first touch electrode and a second touch electrode are arranged on each ITO layer, each first touch electrode comprises a plurality of arc quadrangled stars formed integrally, each side of each arc quadrangled star extends outwards to form a plurality of rectangular branches equal in width, the edges of the rectangular branches are positioned on a same perpendicular line, and the arc quadrangled stars are connected through horizontal angles of the arc quadrangled stars. Each second touch electrode comprises a body which extends to form a plurality of branches, and the width of the body is two times of that of each branch. The first touch electrodes and the second touch electrodes are alternately staggered. By the double-layer ITO wire arrangement structure, detection sensitivity and linearity of ITO layers are remarkably improved.

Description

technical field [0001] The invention relates to an ITO wiring structure, in particular to a double-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] The common double-layer ITO structure is a rhombus s...
