Touch panel

Abstract

The invention discloses a touch panel. The touch panel comprises a base material and a conductive grid pattern. The conductive grid pattern is located on the base material, has conductivity and comprises a circuit zone. The circuit zone is provided with multiple wires, the wires are arranged in a staggered mode in a first direction and a second direction to form a plurality of staggering parts, each staggering part is provided with a protruding part extending from the staggering part, and each staggering part and the corresponding protruding part form a conductive connecting zone. According to the touch panel, the conductive grid pattern with conductivity is arranged on the base material, the wires of the circuit zone of the conductive grid pattern are staggered in the first direction and the second direction to form the staggering parts, each staggering part is provided with one protruding part extending from the staggering part, and each staggering part and the corresponding protruding part form one conductive connecting zone, so that attenuation generated in signal transmission is reduced, and touch input positions are accurately and rapidly responded to.

Description

technical field [0001] The invention relates to a touch panel. Background technique [0002] Various types of touch input technologies have been widely used in electronic products. For example, mobile phones and tablet computers use touch panels as input interfaces. This input interface provides users with an intuitive operation, that is, using The user can give instructions by directly touching the surface of the input panel with a finger or a stylus, or move around the surface of the touch panel to select or operate objects or input handwritten characters. [0003] A conventional touch panel includes at least one base material and conductive patterns, circuit layers, insulating layers, flexible printed circuit board patterns, etc. formed on the base material. Generally speaking, the conductive pattern is made of transparent and conductive Indium Tin Oxide (ITO). However, when the size of the touch panel becomes larger and larger, the area of ​​the indium tin oxide laid o...

Problems solved by technology

However, due to the opacity of metal materials, the aperture ratio often decreases. Therefore, in order to avoid reducing the aperture ratio, the lines of the metal grid are also made thinner and thinner.

However, in the existing process of etching the metal layer by photolithography to manufacture the metal grid pattern, the metal grid often has the problem of disconnection due to excessive etching at the intersection of the lines.
