Abstract
The invention discloses a kind of touch panel, optical waveguide layer is made of black light-blocking film, the second white ink layer, light guiding film and transparent double face glue.It is relatively thin that the invention enables optical waveguide layers, and when stickup does not generate bubble, to promote touch sensitivity, and promotes button graphical display effect.
Description
Technical field
The present invention relates to a kind of touch panels.
Background technology
The touch panel of the prior art, as shown in Figure 1, generally on the back side of the key area of glass cover-plate 01 02 successively
Stacked first black light-blocking film 04, light guiding film 06, the second black light-blocking film 08 and touch module 09, the first black light-blocking film 04 with
The key area 02 of glass cover-plate 01 is bonded by double faced adhesive tape 03, the table of the first black light-blocking film 04 to fit with light guiding film 06
It is printed with the first white ink layer 05 on face, is printed on the surface of the second black light-blocking film 08 to fit with light guiding film 06
Two white ink layers 07, the light that light source is sent out are irradiated to by the loophole on the second black light-blocking film 08 in light guiding film 06,
It is provided with several light directing sites in light guiding film 06, several button figures, light directing site and button are provided on key area
Figure, which corresponds, to be overlapped, and is offered on the first black light-blocking film 04, the first white ink layer 05 and double faced adhesive tape 03 and leaded light
Site and button figure correspond several loopholes overlapped.
Above-mentioned touch panel can make light source pass through by the second black light-blocking film 08, the second white ink layer 07, leaded light
The optical waveguide layer that film 06, the first white ink layer 05, the first black light-blocking film 04, double faced adhesive tape 03 form carries out backlight to button figure
Illumination, but above-mentioned touch panel, due to being provided with double faced adhesive tape 03, the first black light-blocking film 04 and the first white ink layer 05,
So that optical waveguide layer is thicker；And due to being offered on double faced adhesive tape 03, the first black light-blocking film 04 and the first white ink layer 05
Loophole so that after light guiding film 06 fits on the first black light-blocking film 04, be easy so that double faced adhesive tape 03, the first black light-blocking film
04 and first white ink layer 05 loophole in air enter double faced adhesive tape 03, the first black light-blocking film 04 and the first white
Between ink layer 05, so that bubble is generated between double faced adhesive tape 03, the first black light-blocking film 04 and the first white ink layer 05,
It causes to touch insensitive situation；And due to equal on double faced adhesive tape 03, the first black light-blocking film 04 and the first white ink layer 05
Loophole is offered, when light is irradiated to the light transmission on double faced adhesive tape 03, the first black light-blocking film 04 and the first white ink layer 05
It when on hole, is easy to form the ring of light, to influence the display effect of button figure.
Invention content
The technical problem to be solved by the invention is to provide a kind of touch panel, such that optical waveguide layer is relatively thin, when stickup not
Bubble is generated, to promote touch sensitivity, and promotes button graphical display effect.
In order to solve the above technical problems, touch panel provided by the invention, including：
One glass cover-plate is provided with a key area on the glass cover-plate, several button figures is provided on key area
Shape is printed with one first white ink layer on the back side of key area, is provided with and several buttons on the first white ink layer
Figure corresponds several hollow holes overlapped；
One light guiding film, light guiding film are covered on the first white ink layer and by a transparent double face glue and the first white ink
Layer is adhesively fixed, several leaded lights for corresponding and overlapping with several button figures on key area are provided in light guiding film
Site；
One black light-blocking film offers several the first loopholes, the first surface of black light-blocking film on black light-blocking film
On be printed with one second white ink layer, the first surface of black light-blocking film is covered in light guiding film；
One touch module, touch module are covered on the second surface of black light-blocking film.
Preferably, the thickness of the first white ink layer is 10 ~ 20um.
Preferably, the thickness of the first white ink layer is 15um.
Preferably, the key area of the glass cover-plate includes a glass substrate, the back side of glass substrate successively prints
Be formed with a key layer, a mass-tone layer and a black ink layer, setting button figure in key layer, be provided in black ink layer with
Several button figures in key layer correspond several second loopholes overlapped, are provided on mass-tone layer and key layer
On several button figures correspond overlap several third loopholes.
Preferably, the mass-tone layer is third white ink layer.
After using the above structure, compared with prior art, the present invention having the following advantages that：
The touch panel of the present invention, optical waveguide layer is by black light-blocking film, the second white ink layer, light guiding film and transparent double face glue
Composition, thickness reduces compared with the prior art, and need not be arranged between light guiding film and the key area of glass cover-plate
Unthreaded hole will not thus to generate bubble between light guiding film and glass cover-plate so that not will produce gas when pasting optical waveguide layer
Bubble, can be to avoid the insensitive situation of touch；And it need not be arranged between light guiding film and the key area of glass cover-plate
Unthreaded hole can avoid the formation of the ring of light, to promote the display effect of button figure.
