Description
Technical Field
The utility model relates to a liquid crystal display screen technology, in particular to a liquid crystal display screen with a Fresnel lens structure.
Background
A general liquid crystal display screen is generally formed by sequentially stacking a glass cover plate, a touch layer, a front panel and a back plate with a thin film transistor, and the application of the liquid crystal display screen is very wide, but the liquid crystal display screen has certain disadvantages, such as: the visual angle is small, and the brightness and the color are distorted when the viewer looks at the side surface; the other is low contrast, low resolution, low refresh rate and easy failure, and meanwhile, the brightness is insufficient in a strong light environment to cause poor visibility, thereby giving people a very bad experience. And at present liquid crystal display generally adopts to paste the radiation protection membrane and protects against radiation, and single radiation protection membrane is very weak to the effect that the display screen played, brings recessive harm for people's health easily under the condition of long-time the use, not only triggers the disease easily, makes eyes seriously receive the influence moreover.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide the liquid crystal display screen, which has the beneficial effects of being clear, uniform, high in brightness and high in contrast imaging by adding the Fresnel lens and the metal fiber layer and also has the radiation protection function.
In order to achieve the purpose, the utility model provides the following technical scheme: the liquid crystal display screen comprises a glass cover plate, a touch layer, a front panel and a back plate with a thin film transistor, wherein the glass cover plate, the touch layer and the back plate are sequentially stacked, and a Fresnel lens structure is arranged on one side, far away from the touch layer, of the front panel.
Through adopting above-mentioned technical scheme, fresnel lens structure can even reflection light for the image shaping is more clear.
The utility model is further configured to: the Fresnel lens structure and the front panel are arranged in a split mode, and the Fresnel lens structure is composed of a Fresnel lens layer.
By adopting the technical scheme, the Fresnel lens can effectively absorb the influence caused by the ambient light, the visual angle is widened, and the contrast is improved.
The utility model is further configured to: and one surface of the Fresnel lens layer, which is far away from the front panel, is sprayed with titanium dioxide of an anti-radiation layer.
Through adopting above-mentioned technical scheme for the display screen has the function of protecting against radiation, and the spraying deviates from the titanium dioxide of front panel one side at the fresnel lens layer, absorbs the low frequency electromagnetic wave better.
The utility model is further configured to: one side of the smooth surface of the Fresnel lens layer is provided with a metal fiber layer, and the metal fiber layer is attached between the front panel and the back plate.
By adopting the technical scheme, the double-layer anti-radiation effect is achieved, and the metal fiber layer is placed to effectively block radiation because low-frequency electromagnetic wave radiation cannot penetrate through the metal material.
The utility model is further configured to: the front panel, the metal fiber layer and the back panel are sequentially provided with an optical adhesive layer to be bonded together.
By adopting the technical scheme, the stability of the display screen in the aspect of structure is optimized, and the light source is favorable for preventing radiation from penetrating when passing through the display structure.
The utility model is further configured to: the Fresnel lens layer is composed of a plurality of Fresnel lens units which are circularly arranged.
Through adopting above-mentioned technical scheme, fresnel lens unit not only can change the reasonable distribution of light in watching the space, can also eliminate the influence of partly ambient light, improves the contrast of screen and watches the visual angle.
Drawings
FIG. 1 is a diagram of a display structure of an embodiment of a liquid crystal display panel according to the present invention;
FIG. 2 is a Fresnel lens structure according to an embodiment of the present disclosure;
fig. 3 is a cross-sectional view of a display structure of an embodiment of a liquid crystal display panel according to the present invention.
Description of the drawings: 1. the solar cell comprises a glass cover plate, 2 touch layers, 3 front panels, 4 back plates with thin film transistors, 5 Fresnel lens layers and 6 metal fiber layers.
Detailed Description
An embodiment of the liquid crystal display panel of the present invention is further described with reference to fig. 1 and 2.
The utility model provides a liquid crystal display, is including glass apron 1, touch layer 2, the front panel 3 and the backplate 4 that has thin-film transistor that superpose in proper order and set up, one side that the touch layer was kept away from to the front panel is provided with fresnel lens structure. The fresnel lens structure is arranged on the side of the front panel far away from the touch layer, which means that: the circular Fresnel lens layer 5 is an eccentric circle structure with a circle of circles arranged mutually in a front view, the principal ray direction of a horizontal visual angle is controlled by using a circular curvature, and the principal ray direction of an upper visual angle and a lower visual angle is controlled by using sawtooth-shaped bulges on the circular Fresnel lens layer 5. The circular Fresnel lens layer 5 can change the reasonable distribution of the chief rays in the viewing space, can also eliminate the influence of part of ambient light, and improves the contrast ratio of the screen and the viewing angle.
As shown in fig. 3, an anti-radiation layer titanium dioxide is sprayed on one side of the fresnel lens layer 5 away from the front panel 3, and a metal fiber layer 6 is arranged on one side of the smooth surface, wherein the metal fiber layer 6 is attached between the front panel 3 and the back panel 4. Metal fiber layer 6 and the layer of protecting against radiation set up the two sides on fresnel lens layer respectively, low frequency electromagnetic wave has been weakened greatly when through the structural radiation protection layer of fresnel lens, consequently can't pierce through metal fiber layer 6, thereby reached the effect of protecting against radiation, if the position of these both sides takes place to exchange, the effect of protecting against radiation will be influenced, because low frequency electromagnetic wave passes metal fiber layer 6 earlier, during the rethread radiation protection layer, because the radiation protection layer does not have fresnel lens structure, can't decompose the low frequency electromagnetic wave of absorption part, so the effect will weaken.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
