Explosion-proof membrane assembly, touch screen structure and display device

Abstract

The invention provides an explosion-proof membrane assembly, a touch screen structure, and a display device, wherein the explosion-proof membrane assembly includes: an explosion-proof membrane base material, including two opposite surfaces; a frame adhesive, and the frame adhesive is attached to the explosion-proof On at least one surface of the film base material, and located at the edge of the explosion-proof film base material; and a light-transmitting filling layer, the light-transmitting filling layer is filled in the middle area surrounded by the frame adhesive. The explosion-proof membrane assembly provided by the present invention combines the explosion-proof membrane base material and the frame sticker into one, which can reduce the number of times of multiple laminations in the production line, reduce the difficulty of lamination technology, improve the operation yield, and at the same time attach the touch screen to the frame The phenomenon of poor optical interference such as water ripples can be improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to an explosion-proof membrane assembly, a touch screen structure and a display device. Background technique [0002] With the development of science and technology, ordinary display screens of electronic products are gradually being replaced by touch screens, especially capacitive touch screens. OGS (One Glass Solution) is a kind of touch screen structure. Its structure is the technology of directly forming ITO conductive film and sensor on the protective glass, so that a piece of glass can play the dual role of protective glass and touch sensor at the same time. Compared with the traditional The touch screen using the mainstream G / G touch technology has many advantages such as simple structure, light and thin, good light transmission, and low production cost, and the market continues to be optimistic. [0003] The TP (Touch Panel, touch panel) of the OGS structure touch scr...

AI Technical Summary

Problems solved by technology

In order to improve the utilization rate of the frame adhesive cutting material, the frame adhesive is generally cut into strips or L-shaped, which increases the number of times the frame adhesive is attached, which not only increases the number of attachments, but also makes it difficult to guarantee the accuracy; in addition, Between the TP and the LCM of the frame-mounted touch screen, the surrounding edges are filled and glued by the frame adhesive. There is a gap (Gap) between the middle display area of ​​the TP and the LCM, and the middle display area of ​​the TP is in a suspended state.

Usually, such as figure 1 As shown, an explosion-proof film 40 is pasted on the inner side of the display area of ​​TP 10 (this explosion-proof film can be called an inner explosion-proof film to distinguish it from the outer explosion-proof film attached to the outside of the TP), which has a certain effect on the Gap between TP and LCM. Compensation, but generally the thickness of the explosion-proof film is significantly lower than the thickness of the frame adhesive, so it is difficult to completely solve the problem of TP suspension, and the suspension of the TP display area will cause frequent deformation of the TP when the user touches the screen and presses the screen, reducing the service life of the TP , it may also bring TP partial direct contact with LCM, causing optical interference (such as water ripples, Newton rings, etc.), which brings a lot of inconvenience to OGS touch screen users
