Embodiment Construction

[0027] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0028] see Figure 4 , the invention provides a method for attaching a film material, comprising:

[0029] Step 1. Provide the film material 10 and the back material 20, the film material 10 has an adhesive layer, and the adhesive layer of the film material 10 faces the back material 20 to be attached to the film material, and perform alignment;

[0030] Specifically, in the step 1, a planar base (not shown) is also provided, and the backing material 20 is placed on the planar base.

[0031] Step 2, such as Figure 5 As shown, an attachment roller 30 and a metal gasket 40 are provided, and the metal gasket 40 is placed on the back material 20 on one side of the film material 10, so that the attachment roller 30 is pressed down onto the metal...

Abstract

The invention provides a film sheet attaching method. Before the rolling of an attaching roller, a metal gasket is placed on a back sheet on one side of a film sheet, so that after the attaching roller is pressed downwards onto the metal gasket, the attaching roller rolls from the metal gasket towards the other side away from the metal gasket, of the film sheet. Compared with a method in the prior art that the attaching roller is pressed downwards at the edge of the film sheet to directly roll on the film sheet, the film sheet attaching method disclosed by the invention has the advantage that the formation of linear bubbles, which is caused by transient pressure generated at the edge of the film sheet, is avoided, so that bubbles generated during a film attaching process can be effectively reduced, the qualification rate of film sheet attaching is increased, the method is simple and easy to practice, and production cost in the film attaching process can be reduced.

Description

technical field [0001] The invention relates to the field of display device manufacturing, in particular to a method for attaching a film material. Background technique [0002] With the continuous progress and development of display technology, full lamination technology is widely used in the production of touch display screens, which requires optically clear adhesive (Optically Clear Adhesive, OCA) to connect the cover (Cover Glass) and LCD display module (LCD Module) , LCM) assembly and fit. Among them, OCA is made of optical acrylic adhesive without base material, and then laminated a layer of release film on the upper and lower base layers. It is a double-sided adhesive tape without base material. It is a special adhesive material used for bonding transparent optical components (such as lenses, etc.), and is one of the important raw materials for touch screens. [0003] The existing full lamination technology includes two processes: soft and hard, and hard and hard. A...
