Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to Fig. 3, the utility model provides a kind of positive throwing short focus projection screen with touch-control, anti-zoned including what is set gradually
Hurt layer 1, coloring layer 2, diffusion layer 3, Fresnel Lenses layer 4, reflecting layer 5 and light-absorption layer 6, further includes touch-control structure.
Wherein, the Fresnel of anti-scratch layer 1, coloring layer 2, diffusion layer 3, Fresnel Lenses layer 4, light-absorption layer 5 with routine
Projection screen structure is consistent.
Referring to fig. 2, the touch-control structure includes the upper electrode layer 7, insulating layer 8 and lower electrode layer 9 set gradually.Touch-control
Structure can be capacitance touching control structure, or electromagnetic touch structure.Upper electrode layer 7, insulating layer 8 and lower electrode layer 9 close
Claim to be sense film.
Since the material in the reflecting layer 6 of Fresnel projection screen carrys out reflective projection light using metallic element, as aluminium, silver,
Copper etc., and the material of the upper electrode layer 7 of touch-control structure and lower electrode layer 9 is also metallic element, such as aluminium, silver, copper.Therefore, excellent
Choosing, the reflecting layer 6 of the utility model can function simultaneously as the upper electrode layer 7 of touch-control structure.Therefore, total is reduced to
8 layers, that is, the upper electrode layer 7 is combined into one layer with reflecting layer 5, be arranged between the reflecting layer 5 and light-absorption layer 6 insulating layer 8 and under
Electrode layer 9.
It is horizontal and vertical when the touch-control body of charge will be had close to capacitive sensing film by taking capacitance touching control structure as an example
Capacitance charge will change, thus can judge the position of touch-control body.The principle and capacitance touching control knot of electromagnetic touch structure
Structure is similar, and when the touch-control body with electromagnetic field is close to electromagnetic induction film, horizontal and vertical electromotive force will change, because
And it can judge the position of touch-control body.
When designing metal electrode figure as above, it is contemplated that the reflecting effect in optimal reflecting layer 6, in addition to necessary metal
Route separation, answers reservation metal layer material as much as possible.After completing the production of this reflecting layer, one layer of insulating film is then covered,
Make one layer of metallic pattern electrode, the lower electrode layer 9 as touch-control structure above it again.Making upper and lower metal electrode figure
When shape, semiconductor technology can be used, an entire metal film is first plated on Fresnel Lenses layer, is then lost using exposure development
The technique at quarter is realized graphical；Patterned metal electrode structure can also be realized by the way of silk-screen printing.So far, on
Electrode layer 7 (reflecting layer 6), insulating layer 8, lower electrode layer 9 have completed, and touch-control structure has been formed, meanwhile, Fresnel is thrown
The reflection layer structure of shadow curtain is also to complete.
It referring to fig. 4, preferably, can be by insulating layer 5 in order to further enhance the reflecting effect of projection screen and property simple for structure
It is fabricated to extinction color such as black or dark color, while keeping the anti-short circuit of insulating layer to act on, light-absorption layer 6 is can be used as, replaces luxuriant and rich with fragrance alunite
6 structure of light-absorption layer of your projection screen.That is, light-absorption layer 6 and insulating layer 8 merge into one layer, and it is in reflecting layer 5 (upper electrode layer 7)
Among lower electrode layer 9, totally seven layers of total, more succinctly, meanwhile, light-absorption layer is in front of lower electrode layer, can effectively be kept away
Exempt from the inefficient reflections of lower electrode layer.
Preferably, the rear of the projection screen is equipped with protective layer, and protective layer is usually the support plate of the metal materials such as aluminium sheet,
The signal from screen rear is shielded, it is avoided to interfere touch screen structure.In the embodiment shown in fig. 3, aluminium sheet is arranged in extinction
After layer 6；In the embodiment shown in fig. 4, the rear of lower electrode layer 9 is arranged in aluminium sheet.
The projection screen of the utility model combines touch-control structure, therefore, projection screen is made to have touch function.Compared to normal
The infrared touch technology of rule has high precision and fast response, and does not influence the advantage of border structure.
In conclusion the utility model by the anti-scratch layer that sets gradually, coloring layer, diffusion layer, Fresnel Lenses layer,
Reflecting layer and light-absorption layer further include touch-control structure.Touch-control structure includes the upper electrode layer set gradually, insulating layer and lower electricity
Pole layer.By combination of touch control structure, projection screen is made to have touch function.Compared to conventional infrared touch technology, there is height
Precision, fast-response, and the advantage of border structure is not influenced.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art work as the change and modification that various responses can be made according to the utility model, but these
The change and modification of response all should belong to the protection scope of the utility model the attached claims.
