The protective layer of cover plate described in technical solution of the present invention is non-full-transparency type structure, and light transmittance is 10%-80%,
Therefore, ambient light, when incident described cover plate, can be absorbed a part, when its warp through described protective layer
Cross reflection after again by described cover plate time, through described protective layer outgoing can again by absorb a part.
By foregoing description, herein described cover plate can effectively reduce the exit dose of nature light, therefore,
The normal white liquid crystal display device using described cover plate can be effectively improved normal showing slinkingly of white liquid crystal display device and show
Picture effect.
It is above the core concept of the application, below in conjunction with the accompanying drawing in the embodiment of the present invention, to this
Technical scheme in bright embodiment is clearly and completely described, it is clear that described embodiment is only
It is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this
The every other embodiment that field those of ordinary skill is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but this
Bright other can also be used to be different from alternate manner described here implement, those skilled in the art are permissible
In the case of intension of the present invention, doing similar popularization, therefore the present invention not by following public specifically
The restriction of embodiment.
Secondly, the present invention combines schematic diagram and is described in detail, when describing the embodiment of the present invention in detail, for just
In explanation, represent that the schematic diagram of apparatus structure can be disobeyed general ratio and be made partial enlargement, and described signal
Figure simply example, it should not limit the scope of protection of the invention at this.Additionally, should wrap in actual fabrication
Containing length, width and the three-dimensional space of height.
Based on above-mentioned thought, the embodiment of the present application provides the cover plate of a kind of normal white liquid crystal display device, ginseng
Examining Fig. 2, described cover plate includes: transparency carrier 21, black matrix" 22, protective layer 23 and common electrode
24.Wherein, the range of transmittance of described protective layer is 10%-80%, including endpoint value.
Described transparency carrier 21 includes；Viewing area B and non-display area A is described transparent by being arranged on
The interception of the black matrix" 21 below substrate 21 forms described viewing area B and non-display area A.
In Fig. 2 illustrated embodiment, described black matrix" 22 covers at described transparency carrier 21 lower surface
Non-display area A.Described protective layer 23 covers described black matrix" 22 lower surface and described transparent base
The viewing area B of plate 21 lower surface.Described common electrode 24 covers the lower surface of described protective layer 23.
Visible, the protective layer of described cover plate is non-full-transparency type structure, and light transmittance is 10%-80%, therefore,
Ambient light, when incident described cover plate, can be absorbed a part through described protective layer, when it is through reflection
After again by described cover plate time, through described protective layer outgoing can again by absorb a part.Therefore,
Described cover plate can effectively reduce the exit dose of nature light, it is possible to is effectively ensured to show slinkingly and shows picture effect.
Covering plate structure shown in Fig. 2, its black matrix" 22 is arranged on the non-of described transparency carrier 21 lower surface
Viewing area A.So, for the ambient light of incident viewing area B, described cover plate can effectively reduce display
The ambient light in district go out quantity, but for the ambient light of incident non-display area A, process can not be reduced
The ambient light of outgoing after black matrix" 22 transmitting, the black effect of non-display area A is poor.
In the cover plate of described normal white liquid crystal display device, the material of described protective layer is epoxy resin layer,
Its thickness range is at 0.1um-5um, and in the present embodiment, the thickness of described epoxy resin is 2 μm.Can
Described epoxy resin layer is made to be partial light permeability by being uniformly mixed into additive in described epoxy resin layer
Gray epoxy resin bed, by controlling the content of its thickness and described additive, its light transmittance is existed
Between 10%-80%, described additive can be with graphite etc..
Described transparency carrier 21 is glass substrate, and described black matrix" 22 is metal light shield layer or organic
Material light shield layer.
The problem poor for solving non-display area black effect, with reference to Fig. 3, the embodiment of the present application provides separately
A kind of cover plate of normal white liquid crystal display device.Different from cover plate shown in 2 being, cover plate shown in Fig. 3 is in institute
The lower surface stating transparency carrier 21 directly arranges protective layer 23, at described protective layer 23 lower surface with described
Position relative for non-display area A arranges black matrix" 22, in described black matrix" 22 lower surface and institute
State protective layer 23 lower surface and common electrode is set with described position relative for viewing area B.
Due to covering plate structure shown in Fig. 3, have adjusted the position of black matrix", so, incident at natural light
Time, no matter by ambient light incident for viewing area A or non-display area B, at incident described transparency carrier
21 and after reflection described in outgoing during transparency carrier 21, all can twice through described protective layer 23,
Either show that picture effect all can effectively improve by showing slinkingly of viewing area B or non-display area A.
Test result indicate that, the normal white liquid crystal display device of traditional protective clear layer, ambient light incident its
Intensity after cover plate outgoing again is initial 80%-90%, and cover plate described in embodiment in the application, environment
Light is after twice absorption of described protective layer, and the ambient light of final outgoing is only initial environment light
9%-36%, effectively reduces the intensity of the ambient light of final outgoing.
By foregoing description, the protection of the normal cover plate of white liquid crystal display device described in the embodiment of the present application
Layer be non-full-transparency type structure, light transmittance is 10%-80%, therefore, ambient light when incident described cover plate,
Through described protective layer can by absorb a part, when its through reflection after again by described cover plate, warp
Again a part can be absorbed when crossing described protective layer outgoing.By foregoing description, herein described
Cover plate can effectively reduce the exit dose of nature light, therefore, uses the normal white liquid crystal display dress of described cover plate
Put and can be effectively improved normal showing slinkingly of white liquid crystal display device and show picture effect.
The embodiment of the present application additionally provides a kind of often white liquid crystal display device, described normal white liquid crystal display device
