Abstract
A kind of surface acoustic wave touch screen, belongs to touch screen field, and for the blue light transmittance high that surface acoustic wave touch screen high transmission rate is brought, the present invention provides a kind of elimination some blue light so as to protect the surface acoustic wave touch screen of user's eyes；Including rectangular glass screen body, the upper and lower surface of glass screen body is respectively provided with anti-blue light film layer, the anti-blue light film layer of glass screen body upper surface sets nanometer organic fluoride plated film, nanometer organic fluoride plated film upper strata sets reflection bar lamina, reflection bar lamina includes being arranged on 4 groups of reflection strip arrays at nanometer edge of organic fluoride plated film, sound wave transducing unit, including 2 transmitting transducers and 2 receive transducers are provided with four angles of rectangular glass screen body；The present invention is respectively provided with anti-blue light film layer by the upper and lower surface of glass screen body, so that blue light transmitance is reduced significantly, so as to protect the eyes of user.
Description
Technical field
The invention belongs to touch screen field, and in particular to a kind of surface acoustic wave touch screen.
Background technology
Surface acoustic wave is a kind of mechanical wave propagated along dielectric surface.This kind of touch-screen is by touch-screen, sonic generator, anti-
Emitter and sound wave recipient are constituted, and wherein sonic generator can send a kind of high frequency sound wave and cross over screen surface, when finger is touched
During screen, the sound wave on contact is to be prevented from, and thereby determines that coordinate position.Surface acoustic wave touch screen is not by rings such as temperature, humidity
Border factor influence, resolution ratio is high, there is fabulous scratch resistant property, long lifespan（50000000 fault-frees）, can keep clear bright
Picture quality；Without drift, once corrected when need to only install.
Using surface acoustic wave touch screen, only one layer basic unit's glass is theoretically obtainable between user and display screen
Glass, therefore it can keep clear bright picture quality, compared to capacitance plate, touch screens, touch screen inside is without such as conductive
The structures such as film, increased the definition of image；Although surface acoustic wave touch screen has above advantage, above-mentioned advantage is led in anti-blue light
Domain, is not but advantage；Due to the high transmittance of its light, the transmitance of blue light is also very high；Existing surface acoustic wave touch screen
For public arena, user need not for a long time stare at screen, but with the technological progress of surface acoustic wave touch screen, its purposes
Certainly will be increasingly wider, in the case that user needs long-time concern, injury of its blue light to human eye is also very big.
The content of the invention
The technical problems to be solved by the invention are：The lacking in terms of anti-blue light for existing surface acoustic wave touch screen
Fall into, the present invention provides a kind of surface acoustic wave touch screen with anti-blue light function.
The technical solution used in the present invention is：Including rectangular glass screen body, the upper and lower surface of glass screen body is respectively provided with anti-
Blue light film layer, the anti-blue light film layer of glass screen body upper surface sets nanometer organic fluoride plated film, nanometer organic fluoride
Plated film upper strata sets reflection bar lamina, and reflection bar lamina includes being arranged on 4 groups of reflections at nanometer edge of organic fluoride plated film
Striped array, is provided with sound wave transducing unit, including 2 transmitting transducers and 2 receptions on four angles of rectangular glass screen body
Transducer.
Further, 4 described sound wave transducing units are separately positioned on four angles of rectangular glass screen body, each angle
Upper arrangement 1.
Further, the supersonic frequency of 2 described transmitting transducers is different.
The beneficial effects of the invention are as follows：Hungry surface acoustic wave touch screen of the present invention, with anti-blue light film layer and nanometer
Organic fluoride plated film, not only anti-blue light protect user eyes, its surface also have certain stain resistance.
Brief description of the drawings
Fig. 1 is a kind of structural representation of surface acoustic wave touch screen；
Fig. 2 is a kind of Facad structure figure of surface acoustic wave touch screen.
Specific embodiment
Specific embodiment of the invention is described in detail below in conjunction with the accompanying drawings.
A kind of surface acoustic wave touch screen as depicted in figs. 1 and 2, including rectangular glass screen body 1, glass screen body 1 it is upper and lower
Surface is respectively provided with anti-blue light film layer 2, and nanometer organic fluoride plated film is set on the anti-blue light film layer 2 of the upper surface of glass screen body 1
3, the upper strata of nanometer organic fluoride plated film 3 sets reflection bar lamina 4, and reflection bar lamina 4 includes being arranged on a nanometer organic fluoride
4 groups of reflection strip arrays 41 at the edge of plated film, are provided with sound wave transducing unit 42 on four angles of rectangular glass screen body 1, bag
Include 2 transmitting transducers and 2 receive transducers.
4 described sound wave transducing units are separately positioned on four angles of rectangular glass screen body, and 1 is arranged on each angle
It is individual.
The supersonic frequency of 2 described transmitting transducers is different.
In the present invention, the nanometer organic fluoride in described nanometer organic fluoride plated film has functions, at present
It is related to the sector application of optical mirror slip wider in camera lens, glasses etc..
Described blue light film layer uses blue light material blue light material：Perylene, perylene derivative, porphyrin, porphyrin
One kind in derivative, cumarin, coumarin derivative, acridine or acridine derivatives.
General principle of the invention, principal character and advantages of the present invention has been shown and described above.The present invention is not by upper
State the limitation of embodiment, merely illustrating the principles of the invention described in above-described embodiment and specification is not departing from the present invention
Various changes and modifications of the present invention are possible on the premise of spirit and scope, and these changes and improvements both fall within claimed sheet
In the range of invention.The claimed scope of the invention is defined by appending claims and its equivalent.
