Problems solved by technology

[0002] With the wide application of touch panels, the market demand for large-size touch panels is also increasing. However, during the bonding process of large-size touch panels larger than 5 inches, air bubbles are easily generated inside the touch panel body. Bad phenomena such as load changes and Newton rings
Moisture in the air enters between the touch film and the substrate, which not only affects the operation of the touch panel, but may also cause failure of other electronic mechanisms

Abstract

The invention discloses a large touch panel with through holes and a manufacture method thereof, belonging to the technical field of touch panel composite layer structures and manufacture processes thereof. The large touch panel with through holes comprises a first layer as a nameplate layer, a second layer as a top thread conducting pattern layer, a third layer as a bottom thread conducting pattern layer and a fourth layer as a substrate layer, wherein through holes are arranged at the same positions on the peripheries of the bottom thread conducting pattern layer and the substrate layer. The touch panel is provided with the through holes to realize the sealing state of inner air of the touch panel body and eliminate adverse phenomena of bubbles, load changes, the Newton's ring, and the like which are generated in the touch panel body.

Description

technical field [0001] The invention relates to a large-size touch panel with a through hole and a manufacturing method thereof, and belongs to the technical field of a composite layer structure of a touch panel and its manufacturing process. Background technique [0002] With the wide application of touch panels, the market demand for large-size touch panels is also increasing. However, during the bonding process of large-size touch panels above 5 inches, air bubbles are easily generated inside the touch panel body. Bad phenomena such as load changes and Newton rings. Moisture in the air enters between the touch film and the substrate, which not only affects the operation of the touch panel, but may also cause failures of other electronic mechanisms. [0003] In view of the above technical problems, the present invention adopts the through-hole design to provide space for expansion and deformation of the touch panel during hot pressing and cooling, so that the touch panel ...
