Abstract

A transparent touch panel comprises a first transparent covering layer, an induction layer and a second transparent covering layer which are sequentially connected. The induction layer comprises a first substrate, a first imprinting adhesive layer, a first conducting layer, a tackifying layer, a second substrate, a second imprinting adhesive layer and a second conducting layer which are sequentially connected; the first imprinting adhesive layer is provided with a first network-cable-shaped groove to form into first grids; the first conducting layer comprises conducting materials which are arranged inside the groove and a first lead electrode which is connected with the conducting materials; the second imprinting adhesive layer is provided with a second network-cable-shaped groove to form into second grids; first grids are regular grids and second grids are random grids; the first network-cable-shaped groove and the edge line of the first network-cable-shaped groove are curved lines or fold lines which enables the contact areas between the conducting materials and the groove edges to be enlarged; the second conducting layer comprises the conducting materials which are arranged inside the groove and a second lead electrode which is connected with the conducting materials. The transparent touch panel can maintain good performance due to the fact that the friction force is increased due to the contact area between the conducting materials and the groove is enlarged.

Description

technical field [0001] The invention relates to a touch panel, in particular to a transparent touch panel. Background technique [0002] Transparent touch panels have a wide range of applications, and can be integrated with technologies such as multi-touch and smart display. They can be used as display terminals in various fields such as department store inquiries and vending machines, and have synergistic effects such as display, interaction, and advertising. It is expected that in the near future, with the mass production and large-scale application of this product in China, the scenes in the movie will be seen everywhere in real life, and the transparent touch panel will provide people with information services anytime and anywhere. Capacitive transparent touch panels in the prior art are classified into two types: single-point capacitive and multi-point capacitive transparent touch panels. The multi-point capacitive transparent touch panel includes a substrate, multiple...
