Abstract
The utility model is to provide a kind of idle call touch screen insulating panel, comprise substrate and the ink layer being coated in substrate bottom surface, it is characterized in that, described substrate top surface coated with protective film, described B.B.P is bonded with optical waveguide layer, described optical waveguide layer side is provided with LED light source, described optical waveguide layer bottom surface is provided with photoelectric sensor, the utility model has very strong operability, owing to not adopting capacitance plate and ito thin film formula touch-screen, actual during finger touch screen do not have pickup current, also need not firmly press, the diffuse reflection just utilizing finger to produce can produce photosignal, there is very high sensitivity, have removable diaphragm, panel is not easy to damage, and damage also can be changed easily.
Description
Technical field
The utility model relates to air-conditioning panel manufacturing technology field, particularly relates to a kind of idle call touch screen insulating panel.
Background technology
The capacitive touch screen of current air-conditioning contact type panel many employings glass sandwich or ITO diaphragm type touch-screen, the capacitive touch screen of glass sandwich needs to be arranged on after integral panels, this structure contacting touch-screen by integral panels causes the sensitivity of capacitive touch screen lower, regulate delay of response and have to firmly touch, customer responsiveness is bad; The touch-screen of ITO diaphragm type is because can not region-widely touch, and the key position be merely able to fixing touches, and needs on touch location, stamp keypress function mark.In addition, prior art panel does not have panel protective film or panel protective film is non-exchange, and lose the protection of diaphragm, panel easily scratches, be stained with ash, viscous oil stain etc., touch control sensitivity and accuracy will reduce greatly.
Summary of the invention
For the deficiencies in the prior art, the utility model is to provide one to be quick on the draw, non-damageable idle call touch screen insulating panel.
For achieving the above object, the utility model is achieved by following technical proposals:
A kind of idle call touch screen insulating panel, comprise substrate and the ink layer being coated in substrate bottom surface, it is characterized in that, described substrate top surface coated with protective film, described diaphragm adopts pet film, and this material has higher light transmission, does not also have cull after tearing, also not too easily there are the minute bubbles in the middle of pad pasting, diaphragm can not the control sensitivity of counter plate and accuracy to be impacted and conveniently replaced after diaphragm damages; Described B.B.P is bonded with optical waveguide layer, and described optical waveguide layer side is provided with LED light source, and described optical waveguide layer bottom surface is provided with photoelectric sensor.Its principle is: generation, is reflected from touch-screen cross section according to behind the surface of screen by the light beam sent by LED (light emitting diode).If screen top layer is air, when the angle of incident light meets certain condition, light will reflect completely in screen surface.If but there is the higher material of individual refractive index ratio (such as pointing) to push down panel, the condition of screen surface total reflection will be broken, and segment beam, through surface, projects finger surface.Rough finger surface causes light beam to produce scattering (diffuse reflection), and scattered light arrives photoelectric sensor through after touch-screen, and photoelectric sensor changes light signal into electric signal, and system obtains corresponding touch information thus.
Further, described substrate is acrylic board, and its effect strengthens substrate strength and has good light transmission, in addition, due to the insulating property that acrylic material is good, also make panel have insulation function, make to point the danger that contact surface plate does not exist electric leakage.
Further, described ink layer is provided with control zone breach, and its effect does not block control zone to operate necessary light.
Further, described substrate and the two ends of optical waveguide layer are provided with the baffle plate that cross section is L-type, and two baffle plates are symmetrical arranged, and its effect is fixed substrate and light guide plate, prevent dislocation, and have supporting role to substrate and light guide plate.
Further, described diaphragm top is bonded with easily tears subsides, and its effect prevents diaphragm from occurring damages such as scratching before the use, only need open easily tearing subsides gently during use.
The beneficial effects of the utility model are: the utility model has very strong operability, owing to not adopting capacitance plate and ITO diaphragm type touch-screen, actual during finger touch screen do not have pickup current, also need not firmly press, the diffuse reflection just utilizing finger to produce can produce photosignal, has very high sensitivity; Have removable diaphragm, panel is not easy to damage, and damage also can be changed easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-substrate, 2-ink layer, 3-optical waveguide layer, 4-diaphragm, 5-easily tear subsides, 6-baffle plate, 21-control zone breach, 31-LED light source, 32-photoelectric sensor.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of idle call touch screen insulating panel, comprise substrate 1 and the ink layer 2 being coated in substrate 1 bottom surface, described substrate 1 is acrylic board, its effect strengthens substrate strength and has good light transmission, in addition, due to the insulating property that acrylic material is good, also make panel have insulation function, make to point the danger that contact surface plate does not exist electric leakage.Described ink layer 2 is provided with control zone breach 21, and its effect does not block control zone to operate necessary light.
Described substrate 1 end face coated with protective film 4; described diaphragm 4 adopts the pet film (PET film of namely sticking film for mobile phone use; can bulk purchase; then according to size cutting); this material has higher light transmission; there is no cull after tearing, not too easily occur the minute bubbles in the middle of pad pasting yet, diaphragm can not the control sensitivity of counter plate and accuracy to be impacted and conveniently replaced after diaphragm 4 damages yet.Described diaphragm 4 top is bonded with easily tears subsides 5, and its effect prevents diaphragm 4 from occurring damages such as scratching before the use, only need open easily tearing subsides 5 gently during use.
Described substrate 1 bottom adhe has optical waveguide layer 3, and described optical waveguide layer 3 side is provided with LED light source 31, and described optical waveguide layer 3 bottom surface is provided with photoelectric sensor 32.Its principle is: generation, is reflected from touch-screen cross section according to behind the surface of substrate 1 by the light beam sent by LED light source 31 (light emitting diode).If substrate 1 top layer is air, when the angle of incident light meets certain condition, light will reflect completely on substrate 1 surface.If but there is the higher material of individual refractive index ratio (such as pointing) to push down panel, the condition of substrate 1 surface total reflection will be broken, and segment beam, through surface, projects finger surface.Rough finger surface causes light beam to produce scattering (diffuse reflection), and scattered light is through arriving photoelectric sensor 32 after touch-screen, photoelectric sensor 32 changes light signal into electric signal, and system obtains corresponding touch information thus.
It is that baffle plate 6, two baffle plates 6 of L-type are symmetrical arranged that described substrate 1 and the two ends of optical waveguide layer 3 are provided with cross section, and its effect is fixed substrate 1 and light guide plate 3, prevents dislocation, and has supporting role to substrate 1 and light guide plate 3.
What describe in above-described embodiment and instructions just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
