Abstract
The invention belongs to the technical field of touch display, and provides a full-transparent frameless touch screen, which comprises a transparent glass cover plate, a transparent OCA (Optical Cement) layer and a transparent flexible touch sensing plate which are sequentially laminated, wherein a bulge part with the same material as the touch sensing plate is fixedly arranged on one end of the touch sensing plate, extends outwards and is curved in an arc shape; a flexible printed circuit board is tied on the outer end of the bulge part. According to the full-transparent frameless touch screen, the bulge part can extend to the inner part of a case matched with a touch screen or the back part of a display screen, so that the flexible printed circuit board can be arranged in the inner part of the case or the back part of the display screen, the aim of shielding the flexible printed circuit board by the inner part of the base or the back part of the display screen is achieved, the flexible printed circuit board has no need to be shielded by a frame arranged specially, the touch screen is frameless and full-transparent, and the display area and the touch area of the touch screen are enlarged.
Description
Technical field
The invention belongs to technical field of touch-control display, particularly relate to a kind of all-transparent Rimless touch-screen.
Background technology
At present, the touch sensible sheet of existing touch-screen is after determining with flexible circuit board (FPC) nation, in order to avoid flexible circuit board reveal impact attractive in appearance, all adopt frame flexible circuit board to be sheltered from, exist owing to there being frame, viewing area and touch area certainly will be reduced, also cannot meet the requirement of user's Rimless.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of all-transparent Rimless touch-screen that can expand viewing area and touch area is provided.
The present invention realizes like this, a kind of all-transparent Rimless touch-screen, comprise the clear glass cover plate, a transparent OCA optical cement layer and the transparent flexible touch sensible sheet that are cascading, the length of described glass cover-plate, described OCA optical cement layer and described touch sensible sheet is all equal with width, one end of described touch sensible sheet is installed with a protuberance identical with described touch sensible sheet material, described protuberance stretches out and is convexly curved, and the outer end nation of described protuberance has a flexible circuit board surely.
Preferably, the outer end of described protuberance is determined by anisotropic conductive and described flexible circuit board nation.
Preferably, the material of described touch sensible sheet is that Nano Silver, Graphene or Bao Shike are around glass.
The present invention is by arranging a protuberance identical with touch sensible sheet material in one end of touch sensible sheet, and allow protuberance stretch out and be convexly curved, again flexible circuit board nation is fixed on the outer end of protuberance, therefore, protuberance can be extended to the back of casing internal or the display screen coordinated with touch-screen by the present invention, thus flexible circuit board can be located at the back of casing internal or display screen, the object that flexible circuit board covers up by the back achieving casing internal or display screen, without the need to arranging frame specially to block flexible circuit board, thus achieve Rimless and the all-transparent of touch-screen, expand viewing area and the touch area of touch-screen.
Accompanying drawing explanation
In order to be illustrated more clearly in technical scheme of the present invention, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of all-transparent Rimless touch-screen provided by the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, a kind of all-transparent Rimless touch-screen that the embodiment of the present invention provides, comprise clear glass cover plate 1, transparent OCA optical cement layer 2 and the transparent flexible touch sensible sheet 3 be cascading, length and the width of glass cover-plate 1, OCA optical cement layer 2 and touch sensible sheet 3 are all equal, one end of touch sensible sheet 3 is installed with a protuberance 31 identical with touch sensible sheet 3 material, protuberance 31 stretches out and is convexly curved, and the outer end nation of protuberance 31 has a flexible circuit board 4 surely.
The present invention is by arranging a protuberance 31 identical with touch sensible sheet 3 material in one end of touch sensible sheet 3, and allow protuberance 31 stretch out and to be convexly curved, again flexible circuit board 4 nation is fixed on the outer end of protuberance 31, therefore, protuberance 31 can be extended to the back of casing internal or the display screen coordinated with touch-screen by the present invention, thus flexible circuit board 4 can be located at the back of casing internal or display screen, the object that flexible circuit board 4 covers up by the back achieving casing internal or display screen, without the need to arranging frame specially to block flexible circuit board 4, thus achieve Rimless and the all-transparent of touch-screen, expand viewing area and the touch area of touch-screen.
Preferably, the outer end of described protuberance 31 is determined by anisotropic conductive and flexible circuit board 4 nation, and anisotropic conductive has lower solidification temperature, compared with welding flux interconnected, substantially reduces the thermal stress in interconnection process, decreases stress cracking failure phenomenon; In addition, the interconnection process of anisotropic conductive is very simple, thus improves production efficiency, and reduces production cost.
Preferably, the material of described touch sensible sheet 3 be Nano Silver, Graphene or Bao Shike around windable nano materials such as glass, Nano Silver, Graphene or Bao Shike have conduction, transparent and flexible performance around windable nano materials such as glass.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
