Abstract
The utility model discloses a light-reflecting touch screen which comprises a touch screen body and a display screen arranged right under the touch screen body. The touch screen body comprises an upper glass substrate and a lower glass substrate, a conducting film layer is plated on the lower surface of the upper glass substrate, a conducting film layer is plated on the upper surface of the lower glass substrate, at least one of the upper glass substrate and the lower glass substrate is a photochromic glass layer, and when the upper glass substrate is the photochromic glass layer, the lower glass substrate is a heat-insulating glass layer. Compared with the prior art, the light-reflecting touch screen has the advantages that the photochromic glass layer can adjust light reflecting strength automatically according to strength of sunlight, influence of the sunlight on the display screen is reduced, and the display screen is prevented from aging and being broken; the touch screen body is composed of photochromic glass so that manufacturing cost can be effectively lowered; and the light-reflecting touch screen is simple in structure, low in cost, large in practical value and wide in market prospect.
Description
Technical field
The utility model relates to the touch-screen field, is specifically related to a kind of reflective touch-screen that prevents that display screen is aging.
Background technology
Touch-screen is as a kind of up-to-date computer input apparatus, and it is simple, convenient, the most natural present a kind of man-machine interaction mode.It has given multimedia with brand-new looks, is extremely attractive brand-new multimedia interactive equipment.Be mainly used in inquiry, leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, real estate presell of public information etc.
The equipment of touch-screen is placed in the open air more, and sunlight can shine the LCDs of touch-screen below, and the liquid crystal liquid in the liquid crystal display is very responsive to temperature, if the liquid crystal steam raising can occur in excess Temperature, thus the toxic gas that generates.The LCDs of being everlasting in the market outermost layer arranges a plastic foil, but plastic foil easy degradation and decomposition when sunlight directly shines.
The utility model content
For the deficiencies in the prior art, the utility model proposes a kind of reflective touch-screen, this touch-screen can prevent that too much sunlight from injecting the LCDs that is positioned at below the touch-screen.
In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:
Comprise that a touch screen body and is arranged on the display screen under this touch screen body, described touch screen body comprises a top glass substrate and a lower glass substrate, and the lower surface of described top glass substrate and the upper surface of described lower glass substrate are coated with conductive film layer; Have at least one to be the photochromic glass layer in described top glass substrate and the described lower glass substrate; When described top glass substrate was the photochromic glass layer, described lower glass substrate was the heat-protecting glass layer.
Than prior art, the beneficial effects of the utility model are:
1. the photochromic glass layer can automatically be adjusted reflective intensity according to intensity of sunlight, can reduce solar radiation on display screen impact, prevent the aged deterioration of display screen;
2. touch screen body adopts photochromic glass to form, and can effectively reduce manufacturing cost;
3, the utility model is simple in structure, and is with low cost, has larger practical value and wide market outlook.
Description of drawings
Fig. 1 is the structural representation of the reflective touch-screen of the utility model.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, a kind of reflective touch-screen comprises touch screen body 100 and display screen 200, this display screen 200 be arranged on touch screen body 100 under.Touch screen body 100 comprises top glass substrate 110 and lower glass substrate 120, is coated with conductive film layer at the lower surface of top glass substrate 110 and the upper surface of lower glass substrate 120.In the utility model, top glass substrate 110 and lower glass substrate 120 have at least one to be the photochromic glass layer.
In the utility model, the photochromic glass layer is when the sun or the irradiation of other light, and the color of glass can be gradually dimmed with the light enhancing, when irradiation stops, returning to again original color.Can automatically adjust reflective intensity according to intensity of sunlight when the top glass substrate 110 of touch-screen 100 is the photochromic glass layer, make the irradiation of display screen 200 minimizing sunlight and prevent aged deterioration.At this moment, as preferably, this moment, the lower glass substrate 120 of touch-screen 100 can adopt the heat-protecting glass layer, and this heat-protecting glass layer can be isolated with the heat of outside, and display screen 200 is in the metastable working environment, keeps the stability of display screen 200 work.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
Claims (1)
1. reflective touch-screen, comprise that a touch screen body and is arranged on the display screen under this touch screen body, it is characterized in that: described touch screen body comprises a top glass substrate and a lower glass substrate, and the lower surface of described top glass substrate and the upper surface of described lower glass substrate are coated with conductive film layer; Have at least one to be the photochromic glass layer in described top glass substrate and the described lower glass substrate; When described top glass substrate was the photochromic glass layer, described lower glass substrate was the heat-protecting glass layer.
