Structure of adhering module of touch panel

Abstract

The invention discloses a structure of an adhering module of a touch panel. The structure comprises a protection layer, a touch sensing layer, and an adhesive layer, wherein on the face of the protection layer facing to the touch sensing layer, printing ink is coated on the circumference of the edges to form a first printing ink area; in the protection layer, the printing ink on the periphery of the first printing ink area is thickened to form a second printing ink area; and a height sum of the first printing ink area and the second printing ink area is not less than the thickness of the adhesive layer which is internally clamped after the protection layer is adhered to the touch sensing layer. According to the method disclosed by the invention, the working time for occupying an operating platform by a barricade adhesive manufacture process is saved, the use ratio of the operating platform is improved, and the yield is improved; the processing cost of each touch panel product can be saved, and the reject rate caused by bubble generation is greatly reduced when the protection layer is adhered to the touch sensing layer. The method disclosed by the invention is simple, convenient and easy to implement. By thickening the second printing ink layer on the periphery, the squeeze-out amount is controlled within an allowable specification range, so that the requirements on the appearance and the quality of the touch panel of clients are met.

Description

technical field [0001] The invention relates to a structure for preventing bonding glue from overflowing when a touch panel is bonded, and belongs to the technical field of electronic products. Background technique [0002] In the prior art, during the manufacturing and molding process of the touch panel, the touch sensing layer and the protective layer of the touch panel are generally bonded together with water glue, and the water glue is pressed by the touch sensing layer and the protective layer during lamination. , will overflow from the edges around the touch sensing layer. Generally, the width of the overflow glue is allowed to be a specific specification. In actual operation, the allowable overflow glue specification is often exceeded, which will affect the appearance. Even after wiping, there will be traces, which is difficult to meet Customers' requirements for the appearance quality of touch panels. [0003] At present, the usual way to solve the glue overflow is ...

AI Technical Summary

Problems solved by technology

[0005] 1) After adding the retaining wall glue process, because the retaining wall glue is stickier than water glue, the small air bubbles around the water glue cannot be discharged, resulting in poor adhesion;

[0006] 2) Due to the short shelf life of the retaining wall adhesive, the average amount of retaining wall adhesive per product is very small compared to the amount of water glue, resulting in a large amount of retaining wall adhesive being used beyond the shelf life, wasting costs;

[0007] 3) Increase the coating process of retaining wall glue, which takes up the working time of the working machine and affects the output
