Description
Technical field
The present invention relates to display device manufacture field, more particularly to a kind of membrane material attaching method.
Background technology
With the continuous progress of Display Technique, full coating technique is widely used in the middle of touch display screen production, its
Need to show cover plate (Cover Glass) and LCD by Optical transparent adhesive (Optically Clear Adhesive, OCA)
The vertical laminating of module (LCD Module, LCM) group.Wherein, OCA is to make without base material, then in upper bottom optics acrylic glue
Layer, then respectively one layer of mould release membrance of laminating, are a kind of two-sided glue bands without matrix material, are existed with water white transparency, light transmission rate
More than 90%, the features such as cementing strength is good, is the extraordinary mucilage materialses for cementing transparent optical element (such as camera lens), is
One of important raw and processed materials of touch display screen.
Existing full coating technique includes that soft patch is hard and pastes hard two procedures firmly, wherein, the soft hard operation of patch essentially consist in by
OCA and cover plate carry out visual-alignment, and when it is determined that OCA and cover plate have been aligned, OCA and cover plate are fitted;Hard patch
Hard operation is essentially consisted in carries out visual-alignment by the cover plate of LCM and attachment glue surface, it is determined that the cover plate of LCM and attachment glue surface
During contraposition, LCM is fitted with the cover plate of attachment glue surface, to form display unit.At present in full coating technique, bubble is not
Good is that one kind is most common bad, especially in the soft hard operation of patch, linear bubble often occurs not in the attaching initiating terminal of OCA
It is good.Because, in existing membrane material attaches processing procedure, roller (Roller) and plane base station phase interworking are attached frequently with cylinder
The mode of conjunction carries out the attaching of membrane material:Attach roller to be rolled in membrane material, now attach the extruding work of roller and plane base station
Under, membrane material is tightly bonded together with backing, but is attaching the place of roller starting extruding, because of the generation of instantaneous pressure,
A kind of linear bubble is just readily formed near the edge of membrane material.
As shown in figure 1, in the soft hard operation of patch, the mistake attached to Optical transparent adhesive by the way of roller rolling is attached
Journey specifically, rolled since the attaching initiating terminal of Optical transparent adhesive 200 using roller 100 is attached, exclude Optical transparent adhesive 200 with
Air between cover plate 300 to the end of Optical transparent adhesive 200, wherein, as Figure 2-3, due to attach roller 100 to optical lens
The pressure applied of gelatin 200 is controlled by cylinder, the moment contacted with Optical transparent adhesive 200 is pushed in attaching roller 100, in light
Learn transparent adhesive tape 200 on produce an instantaneous pressure, then will the attaching initiating terminal of Optical transparent adhesive 200 leave one it is linear
Bubble 250.So when linear bubble 250 appears in 310 inside of viewing area of cover plate 300, the follow-up cover plate 300 with
The vertical laminating of LCM groups and after forming display panel, it will make occur a wire striped in display picture.Due to this linear bubble
The 250 touch-control effects that can influence display effect and touch control display, most of production firms can not receive this badness.This
One problem has been one of persistent ailment in display panel manufacture field, is also one of problem that manufacturer is faced in the industry.
In face of this problem, the common practice of prior art is by increasing the means such as the non-display area of panel so that linear
Bubble is away from viewing area, while deaeration treatment is carried out for such bubble as much as possible, but existing defoaming method is all very
Hardly possible effectively removes such bubble.Although above-mentioned way can to a certain extent reduce linear bubble to display effect and touch-control
The influence of effect, but its treatment effect is extremely limited, while can inevitably increase the production cost attached shared by processing procedure,
And the narrow frame to display device has detrimental effect.
The content of the invention
It is an object of the invention to provide a kind of membrane material attaching method, can efficiently solve attaching processing procedure in easily in film
Material edge produces the problem of linear bubble.
To achieve the above object, the present invention provides a kind of membrane material attaching method, comprises the following steps:
Step 1, offer membrane material and backing, the membrane material has adhesion coating, by the adhesion coating of membrane material towards membrane material to be attached
Backing, and aligned;
Step 2, offer attach roller and metallic gasket, and metallic gasket is positioned on backing in the side of the membrane material, make
Attach roller be pressed downwardly onto on metallic gasket, then, make attaching roller since on metallic gasket to the membrane material away from metallic gasket
Another side roll and be downwardly applied to pressure, even if attach roller rolled so that membrane material is fitted on backing.
The material of the metallic gasket is stainless steel.
The thickness of the metallic gasket is identical with the thickness of the membrane material.
In the step 2, the rolling track face for attaching roller covers the membrane material.
The membrane material is rectangle, and in the step 2, the rotating direction of the attaching roller is the length direction of the membrane material,
Width of the length for attaching roller more than the membrane material.
In the step 2, after the metallic gasket is positioned on backing, the metallic gasket is in the membrane material and its phase
Length on the bearing of trend of an adjacent side, not less than the length of the side.
In the step 2, after the metallic gasket is positioned on backing, the metallic gasket is in contact with the membrane material
Connection.
Plane base station is also provided in the step 1, the backing is positioned on plane base station.
Described membrane material attaching method is applied in the hard operation of soft patch of full coating technique, the membrane material for be pasted with weight from
The Optical transparent adhesive of type film, its adhesion coating is Optical transparent adhesive, and the backing is the cover plate of display.
The backing has viewing area and the ink area positioned at viewing area periphery, in the step 1, is aligned
Afterwards, the membrane material is completely covered the viewing area of backing.
Beneficial effects of the present invention:The invention provides a kind of membrane material attaching method, before attaching roller is rolled,
Be positioned over one metallic gasket on backing by the side of membrane material, after attaching roller is pressed downwardly onto on metallic gasket, then makes attaching roller
Opposite side to the membrane material away from metallic gasket since on metallic gasket is rolled, so as to attach the rolling process of roller
In, so as in the rolling process for attaching roller, attach roller rolled since on the metallic gasket of membrane material side, with existing skill
Pushed in the edge of membrane material in art and attach roller and directly the method that is rolled in membrane material is compared, it is to avoid because in membrane material
Edge produces instantaneous pressure and causes the formation of linear bubble, therefore the bubble that can effectively reduce in attaching processing procedure is bad,
The attaching yield of membrane material is improved, and method is simple and easy to apply, can reduce the production cost attached shared by processing procedure.
