Abstract

An OPS full-lamination capacitive screen is characterized by comprising a touch control module, an adhesive layer and a liquid crystal display module which are sequentially arranged in a laminating mode. The touch control module is combined by touch control sensors and a plastic covering board; the adhesive layer is liquid glue or solid OCA (optically clear adhesive); the touch control module is laminated with the crystal liquid display module in a seamless mode through the adhesive layer. According to the OPS full-lamination capacitive screen, the technologies of OGS (one glass solution), OPS and full lamination are combined together to meet the higher and higher requirements of mobile phone screens in the aspects of thickness reduction, weight lightening, lower costs and more sensitive touch control, truer and brighter color rendition and the like; by means of the support of the low-layer liquid crystal display module to the upper-layer soft touch control module, the thickness of the covering board can be as thin as 0.025 mm, so that a simpler structure, lower cost, lightening and thinning, higher touch control sensitivity and high light transmittance can be obtained.

Description

A kind of OPS capacitance plate of fitting entirely

Technical field

The utility model relates to a kind of capacitance plate, relates in particular to a kind of OPS capacitance plate of fitting entirely.

Background technology

The capacitance plate of sandwich construction mainly comprises G/F/F (Glass-Film-Film) structure and G/G (Glass-Glass) structure, the former is subject to high price ito thin film material and grasps in minority Japanese trader hand, and latter's binding yield is generally on the low side, all is the main cause that causes the capacitance plate cost high.In order effectively to reduce the touch-control module cost, satisfy the lightening market trend of terminal consumption electronic product simultaneously, nearly 2 years touch-control dealers actively set about research and development and reduce ito thin film or ito glass consumption, layout development OGS technology.The OGS technology is that inductive layer and cover glass are integrated on a slice glass substrate; from technological layer; the OGS technology possesses following advantage: simple in structure, frivolous, transmittance is high, owing to save a slice glass substrate and bonding process, be conducive to reduce cost, improve the product yield.The processing procedure selection of the induction line that faces along with the OGS technology, the strength maintenance of watch crystal, the problems such as adjustment of control chip progressively overcome solution, and the OGS technology becomes the dominant technology direction of touch-control industry gradually, is one of preferential selection of high-end brand.And the generation of OPS technology also be stem from mobile phone screen to cost reduce, further requirement of aspect such as simple in structure, lighter and thinner.Although the OPS technology with respect to the OGS technology at cost, lightening, aspects such as volume production efficient have superiority, but because only the overlay of plastic cement material does not have the support of glass structure, if adopt the laminating type of traditional capacitance screen, will keep an air layer at touch-control module and LCD MODULE, screen is easy to generate the bending distortion when in use, touch-control sensitivity and transmittance all can descend, this has just limited the application of OPS in the high-end field, usually only can more be considered from the cost aspect to select by some low side brands, and the plastic cement overlay thickness of selecting is also thicker usually, generally could realize the requirement of aspect such as intensity guarantee more than 1mm.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of OPS is provided the capacitance plate of fitting entirely, it has kept OGS, OPS technology with respect to the advantage of traditional sandwich construction capacitance plate, has solved simple OPS structure again because of the too soft problem of bringing of screen material.

The utility model is to realize like this, a kind of OPS capacitance plate of fitting entirely, comprise the touch-control module, tack coat and the liquid crystal display module that are cascading, described touch-control module is combined by the overlay of touch sensor and plastic cement, described tack coat is glue or solid-state OCA optical cement, and described touch-control module is by described tack coat and described liquid crystal display module seamless applying.

Particularly, the material of described overlay is PC, PMMA or PET.

Particularly, the thickness of described overlay is 0.025-2mm.

Capacitance plate of the present utility model with the advantages of OGS, OPS and full coating technique together, reached mobile phone screen more and more higher to thickness reduce, weight lightens, cost is lower and touch-control is sensitiveer, the requirement of the truer aspect such as more bright-coloured of color rendition.OPS of the present utility model fits capacitance plate entirely by the support of lower floor's liquid crystal display module to the soft touch-control module in upper strata, the thickness of its overlay can be as thin as 0.025mm, thereby makes that structure is simpler, cost is cheaper, more lightening, touch-control sensitivity and transmittance more increase.

Description of drawings

In order to be illustrated more clearly in the technical solution of the utility model, to do to introduce simply to the accompanying drawing of required use among the embodiment below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the fit full synoptic diagram of capacitance plate of a kind of OPS that the utility model embodiment provides.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.

As shown in Figure 1, a kind of OPS that the utility model embodiment provides (one plastic solution) capacitance plate of fitting entirely comprises the touch-control module 1, tack coat 2 and the liquid crystal display module 3 that are cascading,

This touch-control module 1 is combined by the overlay (not shown) of touch sensor (not shown) and plastic cement; This overlay can be PC, PMMA or the PET of special processing, and special processing comprises the sclerosis plated film (Hard coating) that strengthens skin hardness, promotes the antireflection (AR) of optical quality, the anti-light (AG), waterproof of dazzling is antifouling etc.The hardness of handling overlay by Hard coating can reach more than the 7H, can reach the hardness requirement of glass material eyeglass level; The full transmittance of visible light of the overlay by processing such as AR, AG can reach more than 90%, and the thickness of overlay can be 0.025-2mm.

This tack coat 2 is glue or solid-state OCA optical cement, and the OCA optical cement is that optics acryl glue is made no base material, at the release film of one deck of respectively fitting again of bottom up and down, is a kind of two-sided applying adhesive tape that does not have matrix material then.When the material hardness of overlay is higher but when toughness is relatively poor (as PMMA), can use glue to fit; When the material of overlay is the PET of softness, then can adopt solid-state OCA optical cement to fit.Owing to adopted above-mentioned tack coat 2, therefore, this touch-control module 1 can be realized seamless applying by tack coat 2 and liquid crystal display module 3.
