Description
Technical field
The present invention relates to rigid planar plate laminating resin sheet, use its duplexer and the purposes of this duplexer.
Rigid planar plate laminating resin sheet more specifically for by two rigid planar plates there is the discrepancy in elevation (section is poor) adaptability and bubble can not be made to recur two sides that the mode of (hereinafter sometimes referred to " recurrent of resistance to bubble ") is fitted in resin sheet respectively.
In addition, the purposes of duplexer and this duplexer more specifically relates to: the duplexer of this resin sheet of sandwiched and stacked two rigid planar plates and the portable information terminal equipment aforementioned duplexer being used as parts and obtaining and capacitive touch panels device.
Background technology
In the past, in order to the display body of mobile equipment or indicating meter is engaged with protecting sheet, the general laminating using double sticky tape to carry out frame shape.But this technology has following problem: the air gap layer between indicating meter and protecting sheet causes scattering-in, causes image quality to reduce.As its technical solution, propose with tackiness agent, acrylic resin landfill air gap layer and reduce internal reflection thus improve the technology (such as with reference to patent documentation 1) of image quality.
In addition in recent years, preferred design is: the baffle plate (bezel) removing the hidden internal electrode from outside, and the design of flat pattern is made on display body surface.In the case, taking having carried out the film adhered in the technology on surface of black printing, in order to make to design the texture applying flexibly glass, proposing the glass gluing after being printed by frame in the technology of display body.
But during the plane of the smooth plate of the such hard of laminating glass and LCD, PDP module etc., the black surround frame printing that only a part is highly different if exist, is difficult to bubble-freely fit.
In addition, the tackiness agent that thickness is thicker compared with the height of the simple discrepancy in elevation also can be used to fit, but Punching Technology precision reduce, can the situation such as to ooze out of the tackiness agent of occurring source from end, there is the danger that yield rate reduces.Therefore expect to develop the thickness less than 400 μm of tackiness agent and the technology of the smooth plate with the discrepancy in elevation of can fitting.
Confirm the following fact further: the confirmation of the weather resistance of electronics is undertaken by accelerating to promote under high temperature, super-humid conditions, but under the high temperature conditions, by autoclave process, the bubble that should once disappear recurs again.
On the other hand, as portable information terminal equipment, the portable information terminal equipment having carried the touch panels such as resistive film mode, condenser type, way of electromagnetic induction, infrared mode has appeared on the market in a large number, wherein capacitive touch panels can carry out 2 detections (multi-point touch), effectively can be applied to mobile goods in recent years.Capacitive touch panels is the mode of the capacitance variations detecting surface, therefore requires uniform electric field.Usually, bubble when slimming, lightness, laminating is mixed in countermeasure, and thin film manner is effective, owing to can form uniform electric field, thus the level and smooth face of glass etc. becomes effective, therefore particularly requires to carry out smooth plate laminating each other in capacitive touch panels.
Internal part as portable information terminal equipment in the past carries out the method for fitting each other, proposes the double-sided adhesive tape obtained at the two sides of the core formed by polyurethane film use tackiness agent in patent documentation 2.
But, the double-sided adhesive tape of patent documentation 2 is when fitting smooth plate and deformable film, even if the discrepancy in elevation had a little is fitted with also can not remaining bubble, but when smooth plate is fitted each other, namely when fitting each other in non deformable face, bubble cannot be evicted from while fit, therefore make bubble be mixed in binding face, be difficult to adapt to the discrepancy in elevation completely further.
To this, propose a kind of two sides adhesive sheet in patent documentation 3, its loss tangent (loss tangent) with dynamic viscoelasticity spectrum is 0.6 ~ 1.5 and storage modulus at 80 DEG C is 1.0 × 10
5the adhering agent layer of more than Pa.
About the two sides adhesive sheet of patent documentation 3; the bubble be mixed into when fitting in image display panel by not having the surface protection panel of the discrepancy in elevation removes by autoclave process; even if promote to make aforementioned bubble bring back to life carrying out thereafter heating further, do not produce new bubble yet yet.
In addition, patent documentation 4 proposes a kind of indicating meter impact resistance film, tan δ when it comprises 25 DEG C be more than 0.5 the 1st layer and 25 DEG C time tan δ less than 0.5 the 2nd layer and 25 DEG C time tan δ be more than 0.5 the 3rd layer.
The bubble produced during laminating is also carried out froth breaking by heating and pressurizing process by the indicating meter impact resistance film of patent documentation 4, also can not pass through along with the time and recur bubble.
