The utility model is related to a kind of touch panel and the mobile terminal containing it.
Background technology
Touch panel of the prior art, is all that polaroid glue-line is attached into liquid crystal display surface, mainly divides frame
Patch and entirely two kinds of laminating types of patch.
Frame patch laminating type refers to touch-screen by foam liquid crystal display is pasted with touch-screen together with.
Full patch laminating type refers to touch-screen by OCA optical cements (OCA English full name：Optically Clear
Adhesive, OCA optical cement are the extraordinary adhesives for cementing transparent optical element).Liquid crystal display and touch-screen are sticked
Stick together.
Such frame patch and entirely two kinds of laminating types of patch, luminous energy when by polaroid to touch-screen, foam that frame is pasted or
The OCA optical cements of full patch, due to middle gap, the particularly foam of frame patch, make luminous energy through superrefraction, reflection, process
In can all cause a part luminous energy disappear, cause the index of refraction of touch-screen to be lifted, so as to reduce outside visibility.

It is preferred that first glue-line is foam, the foam is covered in the inner peripheral of the liquid crystal display.
It is preferred that the pressure-sensitive adhesive layer is pressure sensitive adhesive.
It is preferred that the thickness of the pressure-sensitive adhesive layer is 15-30 μm.
A kind of mobile terminal, the mobile terminal includes touch panel as described above.
Positive effect of the present utility model is：
1st, the touch panel that the utility model is provided has excellent optical property, can reduce the index of refraction of touch-screen,
The outside visible light of lifting, and the optical loss produced when avoiding polarizer sheet sticking on a liquid crystal display；
2nd, closely be bonded together for polaroid and touch-screen by using pressure-sensitive adhesive layer by the utility model, makes polaroid
Surface it is uniform, smooth, it is to avoid generation paster bubble.

Specific embodiment
Name preferred embodiment, and become apparent from intactly illustrating the utility model with reference to accompanying drawing.
As shown in figure 1, the present embodiment provides a kind of touch panel, including liquid crystal display 1, and in liquid crystal display 1
The surface polaroid 2 and touch-screen that cover successively from the inside to the outside.
The touch panel also includes the first glue-line 41 and pressure-sensitive adhesive layer 42.
First glue-line 41 is located between liquid crystal display 1 and polaroid 2, and the first glue-line 41 is used to bond liquid crystal display 1
With polaroid 2.In the present embodiment, the first glue-line 41 is OCA optical cements.The thickness of the first glue-line 41 is 50-200 μm.OCA light
Learning glue has the advantages that OCA consistency of thickness, fillibility are good and it is good not allow to be also easy to produce bubble, transparency.
In other embodiments, the first glue-line 41 is foam, and the foam is covered in the inner peripheral of liquid crystal display 1.Bubble
Cotton is commercially available prod, and in the present embodiment, the offer producer of foam is Rogers producer, product type 4790-92-15031-
