Problems solved by technology

OGS uses photoresist frame material, but the white photoresist on the market is not yet mature. To achieve the same optical effect as the cover plate produced by white ink, the thickness of white photoresist needs to be at least To reach 15um, and add a layer of 1-2um thick black photoresist coated on the white photoresist, this will lead to the possibility of disconnection of the signal line (ITO or metal material) in it when climbing, thus cause malfunction

Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] An embodiment of the present invention provides an explosion-proof film, which includes a transparent substrate, the transparent substrate includes a middle area and an edge area around the middle area, and a light-shielding layer is arranged on the edge area.

[0033] The explosion-proof film provided by the embodiment of the present invention can be used for an OGS touch screen. Since the edge area of ​​the transparent substrate is provided with a light-shielding layer, the optical effect of the touch screen can be improved through the light-shielding layer, thereby reducing the thickness of the photoresist frame in the touch screen, even The setting of the photor...

Abstract

The invention provides a rupture membrane and a manufacturing method thereof, a touch screen and a display device. The rupture membrane comprises a transparent substrate, the transparent substrate comprises an intermediate region and an edge region located on the periphery of the intermediate region, and a shielding layer is arranged on the edge region. The rupture membrane provided by the invention can be used on an OGS touch screen, as the shielding layer is arranged additionally on the edge region of the transparent substrate, the optical effect of the touch screen can be improved by the shielding layer, so the thickness of a light resistance frame in the touch screen can be decreased, and the light resistance frame in the touch screen can be even omitted, accordingly the line breakage probability of a signal line in the OGS touch screen in a climbing process can be reduced.

Description

technical field [0001] The invention relates to the display field, in particular to an explosion-proof membrane and a manufacturing method thereof, a touch screen and a display device. Background technique [0002] Traditionally used capacitive touch screens are generally a structure in which a layer of cover glass and a layer of touch glass are laminated by optical adhesive (OCA) (GG structure). However, as the touch market gradually requires touch screens to be light, thin, Low cost, the GG structure can no longer meet these requirements, and is gradually replaced by GF, GFF, OGS and other touch structures. Compared with the traditional structure, the OGS structure has many advantages such as simple structure, light and thin, good light transmission, and low production cost. Advantages, the market continues to be optimistic. [0003] At present, the lamination methods of TP (TouchPanel, touch screen) with OGS structure and LCM (LCDModule, liquid crystal display module) ma...
