Abstract

The utility model discloses an anti-reflection touch screen which comprises a touch screen panel made of glass or transparent plastic films, an anti-reflection film plated on the touch screen panel and a sensor adhered to the other surface of the touch screen panel, and the sensor is used for touch control. The anti-reflection film comprises a plurality of SiO2 layers and TiO2 layers or Nb2O5 layers. After the anti-reflection film is added, the reflectivity of the surface of the touch screen panel to visible light can be notably lowered, and the light transmittance of the touch screen is increased.

Description

A kind of anti-reflection touch-screen

Technical field

the utility model relates to a kind of touch-screen, particularly a kind of touch-screen with anti-reflection function.

Background technology

existing touch-screen module because need to go to touch through conventional hand, conventionally with face glass or other overlay if PET film is as panel because glass hard (HRC65Yi Shang) is very high and very wear-resisting, face glass is used at most.

transmittance is one of leading indicator of touch-screen, and the surface of glass or PET film etc. to the reflectivity of visible ray conventionally in about 4%-4.1%, this is the one of the main reasons that causes touch-screen transmittance low.

glass or PET film surface to visible ray up to 4% reflectivity, make handheld device in the stronger place of light, can not see screen content as mobile phone, panel computer, as outdoor, want that the screen content of seeing mobile phone or panel computer clearly must be adjusted to brightness very bright, even if be adjusted to very brightly, see screen content clearly also gruelling, and heighten brightness, the power consumption of equipment will inevitably increase, and also can increase the stimulation of eyes simultaneously.

the stimulation of eyes is increased, easily eyes are damaged, and smart mobile phone or panel computer, computer are essential in office and life now, consider to the particularly protection to teenager's eyesight of the protection of eyesight the special the utility model that proposes.

Utility model content

the utility model object is: a kind of touch-screen is provided, and on touch panel, plating has the anti-reflection coating layer of sandwich construction, and the transmittance of touch-screen is increased dramatically.

the technical solution of the utility model is:

an anti-reflection touch-screen, comprises touch panel, is plated on the anti-reflection film on touch panel; Touch panel comprises the second surface that first surface and first surface are oppositely arranged, and on the first surface of touch panel, interval is provided with SiO2 layer and TiO2 layer or the compound anti-reflection film of Nb2O5 layer; On second surface, be provided with the sensor for touch-control.

preferably, touch panel is overlay.From the first surface of touch panel, to first surface far away, be disposed with a SiO2 layer; The one TiO2 or Nb2O5 layer; The 2nd SiO2 layer; The 2nd TiO2 or Nb2O5 layer; Three S's iO2 layer.

preferably, touch panel is glass.From the first surface of touch panel, to first surface far away, be disposed with a TiO2 or Nb2O5 layer; The 2nd SiO2 layer; The 2nd TiO2 or Nb2O5 layer; Three S's iO2 layer.

further, the thickness of a TiO2 or Nb2O5 layer is 20-50nm; The thickness of the 2nd SiO2 layer is 40-80nm; The thickness of the 2nd TiO2 or Nb2O5 layer is 40-120nm; The thickness of Three S's iO2 layer is 60-150nm.

described sensor sticks on touch panel with binder.

described anti-reflection film utilizes the method plating of vacuum sputtering in touch panel surface, every layer of coating is used different materials and thickness difference, make visible ray produce the interference of light through the reflected light of different coating, in the scope of visible ray (400 ~ 700nm), the visible reflectance on touch panel surface is reduced, improved the integral light-transmitting rate of touch-screen.

further, set and accurately control the thickness of each rete in anti-reflection film, under the effect of each rete of anti-reflection film, the visible reflectance on touch panel surface is reduced to below 0.5% by 4% left and right, can significantly improve the integral light-transmitting rate of touch-screen.

the utility model has the advantages that:

1. the utlity model has the function of the visible reflectance that reduces touch panel surface.

2. the anti-reflection film in the utility model can increase the integral light-transmitting rate of touch-screen.

Accompanying drawing explanation

below in conjunction with drawings and Examples, the utility model is further described:

fig. 1 is structural representation of the present utility model.

wherein: 11. touch panels, 12. touch panel sensors, 2. a SiO2 layer, 3. a TiO2 or Nb2O5 layer, 4. the 2nd SiO2 layer, 5. the 2nd TiO2 or Nb2O5 layer, 6. Three S's iO2 layer.

Embodiment

embodiment 1:

as shown in Figure 1, a kind of anti-reflection touch-screen, during some non-glass panels such as touch panel 11 is overlay, touch panel 11 comprises the second surface that first surface and first surface are oppositely arranged, on first surface, plating has the anti-reflection film with multi-layer compound structure, anti-reflection film from first surface is up successively: a SiO2 layer 2, after this layer, can make the more firm of anti-reflection film and touch panel 11 combinations on plating; The one TiO2 or Nb2O5 layer 3; The 2nd SiO2 layer 4; The 2nd TiO2 or Nb2O5 layer 5; Three S's iO2 layer 6.Wherein, the thickness of a SiO2 layer 2 is not limit; The thickness of the one TiO2 or Nb2O5 layer 3 is 20-50nm; The thickness of the 2nd SiO2 layer 4 is 40-80nm; The thickness of the 2nd TiO2 or Nb2O5 layer 5 is 40-120nm; The thickness of Three S's iO2 layer 6 is 60-150nm.

touch panel is combined with touch panel sensor after plating anti-reflection film again, is combined into touch-screen module, then is installed on mobile phone or apparatus such as computer and can uses.

embodiment 2:

the present embodiment is compared with embodiment 1, and touch panel 11 is glass, and at first surface without plating the one SiO2 layer 2, plating the one TiO2 or Nb2O5 layer 3 successively; The 2nd SiO2 layer 4; The 2nd TiO2 or Nb2O5 layer 5; Three S's iO2 layer 6.Anti-reflection film can firmly be plated on touch panel 11 equally.

the utility model has been set up above-mentioned anti-reflection film on touch panel 11, greatly reduce the reflectivity of touch panel surface to visible ray, reflectivity can be reduced to below 0.5% from 4% left and right, increased the transmittance of touch-screen integral body, reduce the power consumption of equipment, also reduced the stimulation to eyes.

those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
