Abstract
The invention discloses a semi-cured OCA (optical clear adhesive) induction film laminating method which comprises the following steps: treating to-be-glued laminated material layers; filling the space between the laminated material layers with an adhesive; laminating and removing bubbles; and performing photocuring of the adhesive using ultraviolet (UV). According to the method disclosed by the invention, semi-cured OCA replaces traditional OCA. The semi-cured OCA combines the advantages of OCA and LOCA (liquid optical clear adhesive); in a form of solid adhesive, the semi-cured OCA is suitable for laminating soft materials; and after the laminating and bubble removal, since the composition comprises an ultraviolet initiator and a monomer which is not completely cured or cross-linked, further curing can be performed through ultraviolet irradiation. After ultraviolet irradiation, the initiator initiates further crosslinking reaction of the monomer, the peeling strength between two layers is enhanced, and the problems of creases and cracking of the layers of a touch module and a display module are avoided when the flexible equipment is repeatedly bent for use.
Description
Technical field
The present invention relates to electronic display field, particularly a kind of semicure OCA sensor film applying method.
Background technology
The wearable device development such as current bracelet, intelligent watch rapidly, touch module wherein between layers and still have employed the laminating type of the curling purposes of inflexibility in the past between touch module and display module, OCA, LOCA of adopting as smart mobile phone panel computer etc. or the laminating of two-sided gum.Although the stripping strength after LOCA laminating is fine and bending tolerance is very excellent, but and be not suitable between flexible curling touch module and display module for soft to soft laminating, OCA or two-sided gum are fitted, film type touch-screen normally uses OCA (Optical transparent adhesive) to fit between layers, and is fitted by OCA, LOCA (Liquid optical clear adhesive) or two-sided gum between film type touch-screen and display screen.This laminating material is applicable for the touch control display apparatus of the curling purposes of inflexibility, but when be applied to needs repeatedly curling touch control display device be just there will be following problem: for soft to soft laminating between touch module and display module, can not fit with LOCA, although the stripping strength after LOCA laminating is fine and bending tolerance is very excellent.Can only fit with OCA or two-sided gum between layers, and under OCA or two-sided gum be fitted in repeatedly curling service condition, easily occur, the problems such as cracking, folding line.
Therefore, need to study a kind of semicure OCA sensor film applying method.
Summary of the invention
In view of this, technical problem to be solved by this invention is to provide a kind of semicure OCA sensor film applying method.This method solve flexible volume district touch control display device in repeatedly curling process, occur that glue-line stripping strength is inadequate, and easily occur the problems such as cracking and folding line.
The object of the present invention is achieved like this:
A kind of semicure OCA sensor film applying method provided by the invention, comprises the following steps:
Process to be glued by subsides material layer;
Cementing agent is being filled between layers by subsides material;
After laminating de-bubble;
With UV-light UV, photocuring is carried out to cementing agent;
Further; described cementing agent is 2-hydroxy-2-methyl-1-phenyl-acetone, 1-hydroxycyclohexyl phenyl ketone, 2-methyl-2-(4-morpholinyl)-1-[4-(methylthio group) phenyl]-1-acetone, T2; the mixture of one or more in 4,6-trimethylbenzoy-dipheny phosphine oxide free radical light trigger.
Further, the mixture of one or more in isobornyl acrylate, isobornyl methacrylate, tripropylene glycol diacrylate, polyoxyethylene glycol (400) dimethacrylate photo-curing monomer is also included in described cementing agent.
Beneficial effect of the present invention is: the present invention adopts semicure OCA to substitute traditional OCA.Semicure OCA, combines the advantage of both OCA and LOCA, due to the form of solid gums own, be applicable to soft to soft laminating, laminating, after finishing, owing to there being the monomer of ultraviolet initiator and incomplete curing cross-linked in composition, so can be solidified further by ultraviolet lighting.The further crosslinking reaction of initiator trigger monomer after illumination, enhance two-layer between peeling force, under the state that flexible apparatus is used in alternating bending, touch module also there will not be the problem of folding line, cracking with display module layer and layer.
Accompanying drawing explanation
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, wherein:
The semicure OCA sensor film applying method schema that Fig. 1 provides for the embodiment of the present invention.
Embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.Should be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
Embodiment 1
As shown in the figure, a kind of semicure OCA sensor film applying method provided by the invention, comprises the following steps:
Process to be glued by subsides material layer;
Cementing agent is being filled between layers by subsides material;
After laminating de-bubble;
With UV-light UV, photocuring is carried out to cementing agent;
Described cementing agent is 2-hydroxy-2-methyl-1-phenyl-acetone, 1-hydroxycyclohexyl phenyl ketone, 2-methyl-2-(4-morpholinyl)-1-[4-(methylthio group) phenyl]-1-acetone, T2; the mixture of one or more in 4,6-trimethylbenzoy-dipheny phosphine oxide free radical light trigger.
The mixture of one or more in isobornyl acrylate, isobornyl methacrylate, tripropylene glycol diacrylate, polyoxyethylene glycol (400) dimethacrylate photo-curing monomer is also included in described cementing agent.
Embodiment 2
The semicure OCA sensor film applying method concrete steps that the present embodiment provides are as follows:
Sensor film and semicure OCA fit;
High pressure de-bubble;
Touch module is fitted with display module semicure OCA;
