Description
Technical field
The utility model is related to a kind of full display of fitting with COF with OCA.
Background technology
OCA optical cements are used for cementing transparent optical element, are that optics acrylic glue is made into no base material, then in upper bottom
Layer, then respectively one layer of release film of laminating, are a kind of two-sided glue bands without matrix material.OCR liquid optical cements are used for transparent
The bonding of optical element, it is adaptable to laminating and assembling between touch screen, sized rectangular glass substrate or other rigid-flex.
However, existing laminated material OCA, OCR full laminating, laminating type just for a kind of LCD of specification,
The display screens such as LED, OLED are fitted and can not carry out LCM display module laminatings.I.e. traditional OCA is shown in middle large scale
Occur during device laminating bubble, bounce-back, filling not enough, xanthochromia, cohesive force be inadequate, yield not high-leveled and difficult heavy industry the problems such as, more
The thicker product filling laminating of display surface frame can not be carried out.OCR fit when occur excessive glue, strike-through, ink edge do not solidify,
Filling is inadequate, xanthochromia, the problems such as yield inefficient difficult heavy industry, and the laminating type can not carry out LCM display module laminatings,
There are problems that the filling of the thicker product of surface frame.
Utility model content
The technical problems to be solved in the utility model is：In order to overcome the deficiencies in the prior art there is provided one kind have COF with
OCA full laminating display, product fraction defective is low, and intensity is high, and cost performance is high.
The utility model solves the technical scheme that its technical problem used：It is a kind of that there is COF to be fitted with the complete of OCA
Display, with monitor body and contact panel or protective glass, the inner face of contact panel or protective glass is fitted with OCA light
Glue is learned, the another side of OCA optical cements is fitted with COF thermoplasticity transparent optical films, and monitor body is fitted in COF thermoplasticities
The another side of transparent optical film.
Further limit, the one side of OCA optical cements described in above-mentioned technical proposal is provided with the first diaphragm, another side
Provided with the second diaphragm.
Further limit, the one side of the transparent optical films of COF thermoplasticities described in above-mentioned technical proposal is protected provided with the 3rd
Cuticula, another side is provided with the 4th diaphragm.
The beneficial effects of the utility model are：Product fraction defective is low, and intensity is high, and cost performance is high, saves manpower, saves wealth
Power；In addition, OCA combinations COF laminating type, hardness is big, flexibility is bad, bullet in large-sized monitor laminating in can solving
Property not enough, the problems such as air bubble problem, bounce problem, ink do not solidify, excessive glue and stress produce xanthochromia, and efficiency high also has
Standby excellent heavy industry.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of OCA optical cements；
Fig. 3 is the structural representation of COF thermoplasticity transparent optical films.
In accompanying drawing marked as：1st, monitor body；2nd, contact panel；3rd, OCA optical cements；3-1, the first diaphragm；3-2、
Second diaphragm；4th, COF thermoplasticities transparent optical film；4-1, the 3rd diaphragm；4-2, the 4th diaphragm.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
See Fig. 1, a kind of full display of fitting with COF and OCA of the present utility model with monitor body 1 and is touched
Control panel 2 or protective glass, the inner face of contact panel 2 or protective glass is fitted with OCA optical cements 3, OCA optical cements 3 it is another
Face is fitted with COF thermoplasticities transparent optical film 4, and monitor body 1 is fitted in the another of COF thermoplasticities transparent optical film 4
Face.The one side of OCA optical cements 3 is provided with the first diaphragm 3-1, and another side is provided with the second diaphragm 3-2.COF thermoplasticities
The one side of transparent optical film 4 is provided with the 3rd diaphragm 4-1, and another side is provided with the 4th diaphragm 4-2.
OCA optical cements 3 are used for the extraordinary adhesive of cementing transparent optical element, it is desirable to water white transparency, light transmission rate
More than 90%, cementing strength it is good, can solidify under room temperature or middle temperature, and have the features such as cure shrinkage is small.OCA optical cements 3
It is one of raw material of important touch-screen, is that optics acrylic glue is made into no base material, then in bottom up and down, then each laminating one
Layer release film, is a kind of two-sided glue band without matrix material.In brief, OCA optical cements 3 are exactly with optical clear
One layer of extraordinary double faced adhesive tape.OCA optical cements 3 have good resiliency, reduce yellow side and the fraction defective of product.
The main component of COF thermoplasticities transparent optical film 4 is EVA-PMMA concurrent mixture, and EVA is the acetic acid second of ethene one
Enoate copolymer, there is good resistance to low temperature, is widely used in cold-resistant product and cold-resistant field；PMMA is polymethylacrylic acid
Methyl esters, shows extremely superior in terms of the transparency, weatherability and impact resistance.The product made using COF materials, in items
While index reaches and surmounts OCA, OCR making product, the indeterminable laminating difficult points of OCA and OCR are also solved, significantly
Product fraction defective is reduced, several times improve the intensity of panel, significantly save human resources, so that product cost is improved, should
Material is that the optimal selection of touch-control display laminating is also a technological innovation in the field.
This it is full laminating display manufacturing process be：Take the first diaphragm 3-1 in OCA optical cements 3 off laminatings first
In contact panel 2 or the inner face of protective glass, then take the second diaphragm 3-2 in OCA optical cements 3 off, can while taking COF heat off
COF thermoplasticities transparent optical film 4, is taken off the 3rd diaphragm 4-1's by the 3rd diaphragm 4-1 in plastic transparent optical film 4
With OCA optical cements 3 take off the second diaphragm 3-2 while fitted, finally take COF thermoplasticity transparent optical films off
The 4th diaphragm 4-2 in 4 carries out contraposition with monitor body 1 and fitted, then carries out vacuum hotpressing.OCA combinations COF laminating
Mode, hardness is big, flexibility is bad in large-sized monitor laminating in can solving, it is elastic not enough, air bubble problem, bounce-back ask
The problems such as filling and stress that topic, ink do not solidify, excessive glue, display surface frame are thicker produce xanthochromia, and efficiency yield is high, also
Possesses excellent heavy industry.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
