Problems solved by technology

However, the Free Shape technology still has some shortcomings. For example, it is easy to pull or lack glue at the corner or continuous corner, or the shape of the corner is incomplete; especially when the curing rate of the glue is too high or too low , the incidence rate of rubber pull or lack of glue will start to be high; after lamination, these positions with lack of glue or severe glue pull are prone to appearance and quality problems

Embodiment Construction

[0027] The invention provides a method for applying glue more accurately on the surface of a specific area of ​​an object.

[0028] figure 1 It is a flow chart of the gluing method provided by the embodiment of the present invention. Such as figure 1 Shown, this gluing method comprises the following steps:

[0029] Step S1: if figure 2 As shown, a substrate 10 and a protective film 20 are provided, and the protective film 20 is provided with a hollow area 21 . The substrate 10 defines a display area 101 and a frame area 102 surrounding the display area 101 . In one embodiment, the frame area 102 may be an area provided with an ink layer.

[0030] The material of the substrate 10 may be glass or an optical substrate. The material of the optical substrate can be, but not limited to, polycarbonate (Polycarbonate, PC), polymethyl methacrylate (Polymeric Methyl Methacrylate, PMMA) or polyethylene terephthalate (polyethylene glycol terephthalate, PET) etc.

Abstract

A cement coating method comprises the following steps that a base plate and a protective film are provided, and the protective film is provided with a hollowed-out area; the protective film is pastedto the base plate, and the area, opposite to the hollowed-out area, of the base plate is exposed; the surface, with the protective film, of the base plate is coated with optical cement, the hollowed-out area is completely filled with the optical cement, and at least part of the optical cement covers the protective film; the optical cement is solidified; the solidified optical cement is cut, and the optical cement in the hollowed-out area and the optical cement on the protective film are separated; and the protective film is removed from the base plate. Through the cement coating method provided by the invention, the cement feathering or cement missing phenomenon can be avoided.

Description

technical field [0001] The invention relates to the technical field of bonding, in particular to a glue application method. Background technique [0002] With the continuous development of display screen narrow frame technology, the diversity of glue coating shapes, Free Shape (Free Shape) technology is born. However, the Free Shape technology still has some shortcomings. For example, it is easy to pull or lack glue at the corner or continuous corner, or the shape of the corner is incomplete; especially when the curing rate of the glue is too high or too low , the incidence rate of glue pulling or lack of glue will start to be high; after lamination, these positions with lack of glue or severe glue pulling are prone to appearance and quality problems. Contents of the invention [0003] A kind of gluing method, it comprises the following steps: [0004] Step S1: providing a substrate and a protective film, the protective film is provided with a hollow area; [0005] Step...
