Dazzle is a kind of bad illumination phenomenon, when the brightness of light source is high or the luminance difference at background and center, the visual field is when larger, will produce dazzle.While driving night as the driver, by the licence of opposite switch-on distance light, to be penetrated be exactly that a kind of dazzle is polluted to unexpected eyes.The unexpected eyes of waking up in sleeping night are also that a kind of dazzle is polluted by light-illuminating.It is uncomfortable that dazzle gently makes eyes produce, heavy can harm one's eyes, and bears especially for a long time the dazzle pollution, can allow the teenager easily suffer from myopia, and the elderly obtains cataractous probability and significantly rises.Anti-dazzle effectively reduces this effect.Even also can see clearly in the sun.
Yet giant-screen of the prior art, because the effect of dazzle causes, can not any angle before giant-screen can watch the content shown in screen.
The utility model content
The utility model proposes a kind of display screen and giant-screen, solved in the prior art problem that can not any angle before giant-screen can watch the content shown in screen.
The technical solution of the utility model is achieved in that
A kind of display screen comprises:
Carry out the ground floor of initial refraction for the light that grenade instrumentation is sent;
The second layer that carries out birefringence for the light that grenade instrumentation is sent;
Carry out three refractions for light that grenade instrumentation is sent, and eliminate grenade instrumentation and send dazzle subsidiary in light, and the 3rd layer that the second layer is protected;
The first fixed bed for ground floor and the second layer are fixed together, be arranged between ground floor and the second layer;
For by the second layer and the 3rd layer of the second fixed bed be fixed together, be arranged between the second layer and the 3rd layer.
As further technical scheme, also comprise:
The antireflection film reflected for the light that grenade instrumentation is sent, be separately positioned on the ground floor two ends.
Preferably, ground floor is specially the ultra-clear glasses ground floor.
Preferably, the 3rd layer is specially the 3rd layer of anti-dazzle.
A kind of giant-screen, comprise support body, and grenade instrumentation also comprises display screen, and ground floor is arranged on support body.
The beneficial effect of technical solutions of the utility model:
1, by the matching design of ground floor, the second layer and the 3rd layer, the light that makes grenade instrumentation send by ground floor, the second layer and the 3rd layer of refraction after, avoided the generation of dazzle, finally realize that full visual angle watches;
2, by the design of the first fixed bed and the second fixed bed, make the volume of the display screen after having combined less, save floor area;
3, the design by antireflection film reduces the light that grenade instrumentation sends and is reflected, so avoided due to light emission too much impact project the quality of image.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model a kind of display screen part-structure enlarged diagram and light refraction figure;
The structural representation that Fig. 2 is a kind of giant-screen of the utility model;
Fig. 3 is A part-structure enlarged diagram in Fig. 2.
In figure:
1, ground floor; 2, the second layer; 3, the 3rd layer; 4, the first fixed bed; 5, the second fixed bed; 6, support body.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figures 1 to 3, a kind of display screen the utility model proposes comprises:
Carry out the ground floor 1 of initial refraction for the light that grenade instrumentation is sent;
The second layer 2 that carries out birefringence for the light that grenade instrumentation is sent;
Carry out three refractions for light that grenade instrumentation is sent, and eliminate grenade instrumentation and send dazzle subsidiary in light, and the 3rd layer 3 that the second layer 2 is protected;
The first fixed bed 4 for ground floor 1 and the second layer 2 are fixed together, be arranged between ground floor 1 and the second layer 2;
For by the second layer 2 and the 3rd layer of 3 the second fixed bed 5 be fixed together, be arranged between the second layer and the 3rd layer 3.
In an embodiment of the present utility model, by the first fixed bed 4, ground floor 1 and the second layer 2 are fixed together, by the second fixed bed 5, the second layer 2 and the 3rd layer 3 are fixed together, ground floor 1 ultra-clear glasses ground floor 1 preferably wherein, after entering into ground floor 1, light that grenade instrumentation sends initially reflects by ground floor 1, light after refraction enters the second layer 2, by the second layer 2 in further refraction, enter the 3rd layer 3 by the light after the second layer 2 refractions, reflect rear and then shown by the 3rd layer 3, by ground floor 1, the layer refraction of the second layer 2 and the 3rd layer 3, can eliminate the dazzle in the light that grenade instrumentation sends, and can make the imagery coverage projected maximize, carry out when reducing the display screen volume realizing that full visual angle shows, be that such beholder is in 180 ° of scopes, can clearly watch the information of demonstration, can be because of the angle difference, cause the appearance of problems such as watching that demonstration information is not known, even also can see the content shown in screen clearly in the sun.
