Abstract
The utility model discloses a double-light source infrared touch screen optical reflective film, mainly comprising an infrared film (1) which absorbs visible light, and transmits and reversely reflects infrared rays for 180 degrees, and a metal layer (2) which is arranged below the infrared film (1). The upper surface of the infrared film (1) is a smooth interface, and the lower surface of the infrared film is the interface which is formed by a micro-prism structure with optical reverse reflectivity. A 2 light-emitting diode (LED) optical infrared touch screen which adopts the structure and is made from the reflective film has the characteristics of simple process, low cost, low fault rate, high resolution and support of multi-point touch control, and the cost of any size of the reflective film is hardly increased.
Description
Technical field
The utility model relates to a kind of film, specifically is to visible absorption, the ultrared two light source type infrared touch panel optics reflective membranes of reflex reflection.
Background technology
Along with the development of information science technology, multimedia information inquiry grows with each passing day, and the range of application of touch-screen is also more and more wide, as the service inquiry of departments such as telecommunication bureau, the tax bureau, bank, electric power; The information inquiry in street corner, city; Be applied to lead office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, real estate presell etc. in addition.
Touch screen technology is the mainstream technology that reaches following very long one period at present, and market research and demand are extremely swift and violent.The main implementation of touch screen technology has following four kinds at present: resistive touch screen, capacitive touch screen, surface acoustic wave type touch-screen and infrared type touch-screen, and wherein, resistive touch screen is mainly used in the product below 3 inches; Capacitive touch screen can only be produced the product below 9 inches, and its cost height; The surface acoustic wave type touch-screen has the cost height, and stability is bad, is subject to characteristics of interference; Infrared type touch-screen applications scope is wide, can be used for 10～200 inches display screens and electronic whiteboard.Giant-screen (more than 10 inches) major part all adopts infrared type, the characteristics that for the infrared type touch-screen that exists now, ubiquity cost height, complex process, failure rate height, resolution be low, do not support multi-point touch.
How to pass through to improve, make the infrared type touch-screen can overcome above shortcoming, this becomes present social question of common concern, yet, also there is not corresponding apparatus now, do not see relevant report yet.
The utility model content
The purpose of this utility model is to overcome the defective of infrared type touch-screen existence now, provides a kind of 2LED optical profile type infrared touch panel that can make to have the two light source type infrared touch panel optics reflective membranes that technology is simple, failure rate is low, resolution is high and support multi-point touch.
The purpose of this utility model is achieved through the following technical solutions:
Infrared touch panel optics reflective membrane, by absorption visible light, transmission and 180 ° of ultrared infrared ray retes of reflex reflection, and the metal level under the infrared ray rete constitutes.
The infrared ray rete is transparent plastic cement or glass.The thin layer that the infrared ray rete is mainly made by more than one the material among polycarbonate PC, polymethyl methacrylate PMMA, polyvinylchloride, poly terephthalic acid PET, polyamide PA, the polystyrene PS.
The upper surface of infrared ray rete is level and smooth interface, and its lower surface is the interface with micro-prism structure formation of optics retroreflective.
The utility model compared with prior art has following advantage and beneficial effect:
(1) infrared ray rete of the present utility model is made by the material that absorbs visible light, transmits infrared, the lower surface of infrared ray rete is a micro-prism structure, microprism transmissive infrared ray also makes infrared ray turn to 180 °, the infrared ray of any angle incident is through behind the microprism, and its reflection ray all is parallel with its incident ray and becomes 180 degree anti-phase.
(2) the utility model adopts the infrared ray rete with microprism, and the structure of the formation of the metal level under the infrared ray rete, make that to the utlity model has 0 degree retroreflective when 60 spend good, the intensity of light reflection test curve is near the characteristics of horizontal linear (reaching optimum Working), and have the resolution height, support the performance of multi-point touch.
(3) employing lower surface of the present utility model is provided with the infrared ray mould layer structure of microprism, use the 2LED optical profile type infrared touch panel of the utility model manufacturing to have the advantages that technology is simple, cost is low, failure rate is low, resolution is high, support multi-point touch, and virtually any size increase cost hardly.
Description of drawings
Fig. 1 is the local sectional structure synoptic diagram that amplifies of the present utility model;
Fig. 2 is the structural representation of the microprism of the utility model infrared ray rete.
Embodiment
Below in conjunction with embodiment the utility model is further described, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figures 1 and 2, two light source type infrared touch panel optics reflective membranes, mainly by absorption visible light, transmission and 180 ° of ultrared infrared ray retes 1 of reflex reflection, and the metal level under the infrared ray rete 12 constitutes.Infrared ray mould layer 1 mainly can be made the thin layer that the material of transparent plastic cement or glass is made by polycarbonate PC, polymethyl methacrylate PMMA, polyvinylchloride, poly terephthalic acid PET, polyamide PA, polystyrene PS etc., for the selection of above-mentioned material can be select wherein a kind of, perhaps multiple mixing, by adding other material again, can realize to the high-absorbility of visible light with to the high transmittance of infrared ray and 180 ° of reflex reflections.Infrared ray rete 1 also can be the common transparent thin film layer that constitutes of plastic cement and glass, considers optical characteristics, and the color of infrared ray rete 1 is selected black the best.
The upper surface of infrared ray rete 1 is level and smooth interface, and its lower surface is the interface with micro-prism structure formation of optics retroreflective.Because the absorption of 1 pair of visible light of infrared ray rete, the infrared ray of microprism reflex reflection incident, and make that the infrared ray of reflection is parallel with the infrared ray of incident and become 180 ° anti-phase.The coating that metal level 2 constitutes for the mode of plated film, wherein nickel plating, aluminium, silver, gold are most common form.
Of the present utility model fixing can be by having gum layer at metal level 2, and this gum layer has adherent layer, when using the utility model, only needs adherent layer is taken off, and gum layer can be sticked on the required interface.Can also be fixed on the frame or by securing member and be fixed on the frame with inside casing or other fixed form.
The utility model is one of core component of latest generation infrared touch panel, and the performance of 2LED optical profile type infrared touch panel is played key effect.
As mentioned above, just can well realize the utility model.
