Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Refer to attached picture. The glass cover plate 1 of the 3D touch screen of the mobile terminal is a curved 3D structure.

[0021] In the laminating process, the glue A is used as the dam glue, and the surface glue is added with the curing catalyst B glue. Before the surface glue is cured and after curing under the curing conditions, the dam glue is always in a gel state, so that the dam The glue always maintains good thixotropy, and the process method of the present invention does not require the dam glue and surface glue to maintain high-precision flatness, so that the bonding of the curved 3D touch screen has good manufacturability.

[0022] Among them, the B glue and the A glue use the same type of glue, and ...

Abstract

The invention provides an AB-type water glue laminating process for a cambered 3D touch screen or display screen. The AB-type water glue laminating process comprises the following steps that (1) dam glue is dispensed on a glass cover plate of the cambered 3D touch screen or display screen to form a glue frame, wherein the height of the dam glue is comprehensively higher than the lower surface of adisplay module of the 3D touch screen or display screen; (2) surface glue is dispensed in the glue frame; (3) the display module is attached to the surface glue; (4) curing is conducted; and (5) uncured dam glue is wiped off. According to the AB-type water glue laminating process for the cambered 3D touch screen or display screen, A glue in the surface AB glue is used as the dam glue, a curing agent B glue is not added into the A glue, the A glue cannot be cured in a high-temperature and conventional environment, the thixotropy is high, the A glue and the surface glue are in the same system and do not react with each other, and therefore the appearance effect and the curing effect cannot be affected; after surface glue curing is achieved, the dam glue is still in an initial dispensing state and has good thixotropy and formability, excessive glue does not exist, and laminating of a complex cambered touch screen is easy to achieve.

Description

technical field [0001] The invention relates to a water-glue bonding process for a curved 3D touch screen and a flat display screen. Background technique [0002] In the 3D touch screen water-glue lamination of mobile terminals such as mobile phones, since the glass cover is a curved surface, it is very difficult to obtain the same shape as the curved glass by using the common process for the dam glue; the solution for making profiling fixtures is easy to glue Bonding with the jig will cause glue pulling and uneven cutting surface. Contents of the invention [0003] The purpose of the present invention is to provide an AB-type water-glue bonding process for a curved 3D touch screen or display screen, to solve the problem that ordinary dams need to be cured and cannot obtain the same shape as the glass cover in curved-surface 3D water-glue bonding. For this reason, the present invention adopts following technical scheme: [0004] An AB-type water-glue bonding process for ...
