Abstract
A kind of surface acoustic wave touch screen, belongs to touch screen field, and for high blue light transmittance caused by surface acoustic wave touch screen high transmission rate, the utility model 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 4 groups of reflection strip arrays for being arranged on 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 utility model in the upper and lower surface of glass screen body by being respectively provided with anti-blue light film layer, so as to reduce blue light transmitance significantly, so as to protect the eyes of user.
Description
Technical field
The utility model 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 composition, wherein sonic generator can send a kind of high frequency sound wave and cross over screen surface, when finger touches
During screen, the sound wave on contact is prevented from, and thereby determines that coordinate position.Surface acoustic wave touch screen is not by rings such as temperature, humidity
Border factor influences, and resolution ratio is high, there is fabulous scratch resistant property, long lifespan（50000000 fault-frees）, can keep clear bright
Picture quality；Do not drift about, once corrected when need to only install.
Using surface acoustic wave touch screen, only one layer of 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, without such as conductive inside touch screen
The structures such as film, add the definition of image；Although surface acoustic wave touch screen has above advantage, above-mentioned advantage is led in anti-blue light
Domain, but it is not 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 stare at screen for a long time, but with the technological progress of surface acoustic wave touch screen, its purposes
Certainly will be increasingly wider, in the case of long-time concern is needed for user, injury of its blue light to human eye is also very big.
Utility model content
Technical problem to be solved in the utility model is：For existing surface acoustic wave touch screen in terms of anti-blue light
Defect, the utility model provide a kind of surface acoustic wave touch screen with anti-blue light function.
Technical solution adopted in the utility model is：Including rectangular glass screen body, the upper and lower surface of glass screen body is all provided with
Anti-blue light film layer is put, the anti-blue light film layer of glass screen body upper surface sets nanometer organic fluoride plated film, nanometer Organic fluoride
Compound plated film upper strata sets reflection bar lamina, and reflection bar lamina includes be arranged on nanometer edge of organic fluoride plated film 4 groups
Reflection strip array, sound wave transducing unit, including 2 transmitting transducers and 2 are provided with four angles of rectangular glass screen body
Receive 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 utility model are：Surface acoustic wave touch screen described in the utility model, there is anti-blue light film layer
With the eyes of nanometer organic fluoride plated film, not only anti-blue light protection user, its surface also has 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.
Embodiment
Specific embodiment of the present utility model 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 up and down
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, sound wave transducing unit 42 is provided with four angles of rectangular glass screen body 1, wrap
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 utility model, the nanometer organic fluoride in described nanometer organic fluoride plated film has functions,
The sector application for being related to optical mirror slip in camera lens, glasses etc. at present is wider.
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.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.This reality
It is not restricted to the described embodiments with new, simply illustrates original of the present utility model described in above-described embodiment and specification
Reason, the utility model also has various changes and modifications on the premise of the spirit and scope of the utility model is not departed from, these changes
Change and improve and both fall within claimed the scope of the utility model.The utility model requires protection scope is by appended right
Claim and its equivalent define.
