Reflectance coating and the liquid crystal module of using this reflectance coating
Technical field
The utility model relates to a kind of blooming, the liquid crystal module that particularly relates to a kind of reflectance coating and use this reflectance coating.
Background technology
Nowadays, mobile phone, electronic products such as computer display screen mostly are LCDs, and LCDs generally includes liquid crystal panel and backlight panel, and backlight panel provides light source for liquid crystal panel is provided.
As shown in Figure 1, it is the cross section structure synoptic diagram of traditional backlight panel 10, and backlight panel 10 comprises framework 101, light guide plate 102, light source 103 and reflectance coating 104.
Light guide plate 102 is assemblied in the described framework 101, and described light source 102 is positioned at the side of light guide plate 102, is used to light guide plate 102 that light source is provided.
Reflectance coating 104 is attached on the framework 101 by double faced adhesive tape, is attached at simultaneously on the surface of described light guide plate 102.For the light reflected back light guide plate 102 that light guide plate 102 is shone on the reflectance coating 104, to reduce the loss of light, improve display brightness.
Yet, when reflectance coating 104 is attached on the framework 101, be difficult to accomplish reflectance coating 104 and the perfect butt of the sidewall of housing 101, all can leave certain clearance 150 usually.During backlight panel 10 work, the part light on the light guide plate 102 just can expose from this gap, i.e. electronic product generation light leak influences the electronic product quality.
The utility model content
Based on this, be necessary to provide a kind of can less light leak reflectance coating and the liquid crystal module of using this reflectance coating.
A kind of reflectance coating comprises reflector plate and the ink lay that is attached to a surface of described reflector plate, and described ink lay is black.
Among one of them embodiment, described reflector plate comprises: protective finish, silver layer, pet layer, aluminium lamination and white substrate layer; The ink lay of described black is attached to the surface of described white substrate layer.
Among one of them embodiment, described protective finish, described silver layer, described pet layer, described aluminium lamination and described white substrate layer are fitted successively.
Among one of them embodiment, described ink lay is the water-based print ink that makes through chemical process and physical mixed by aqueous high molecular emulsion, organic pigment, resin, surfactant and associated additives.
A kind of liquid crystal module comprises liquid crystal panel and the backlight panel of mutual butt, and described backlight panel comprises housing, light guide plate, light source and reflectance coating,
Described light guide plate mount is in described housing;
Described light source is assemblied in the described housing and is positioned at the side of described light guide plate;
Described reflectance coating be attached on the described housing and with a surperficial butt of described light guide plate, the surperficial butt of another of described liquid crystal panel and described light guide plate;
Described reflectance coating comprises reflector plate and is attached to the ink lay on a surface of described reflector plate, and described ink lay is black and away from described light guide plate.
Among one of them embodiment, described reflector plate comprises: protective finish, silver layer, pet layer, aluminium lamination and white substrate layer; The ink lay of described black is attached to the surface of described white substrate layer.
Among one of them embodiment, described protective finish, described silver layer, described pet layer, described aluminium lamination and described white substrate layer are fitted successively.
Among one of them embodiment, described ink lay is the water-based print ink that makes through chemical process and physical mixed by aqueous high molecular emulsion, organic pigment, resin, surfactant and associated additives.
After above-mentioned liquid crystal module was used above-mentioned reflectance coating, though a little gap is arranged between reflectance coating edge and the framework unavoidably, and the ink lay of black can effectively send light guide plate and pass the light in this gap and sponges, and to eliminate the electronic product light leak bad and reach.

Fig. 2 is the cross section structure synoptic diagram of the reflectance coating of the utility model one embodiment;
Fig. 3 is the liquid crystal module structural representation of the use of embodiment reflectance coating shown in Figure 2.
Embodiment
As shown in Figure 2, it is the cross section structure synoptic diagram of the reflectance coating 20 of the utility model one embodiment.
Reflectance coating 20 comprises reflector plate 201 and is attached to the ink lay 202 on 201 1 surfaces of described reflector plate.Described ink lay 202 is black.
Described reflector plate 201 comprises successively fits: protective finish 211, silver layer 212, PET(Polyethylene Terephthalate) layer 213, aluminium lamination 214 and white substrate layer 215.
The ink lay 202 of described black is attached to the surface of described white substrate layer 215.
In the present embodiment, ink lay 202 is through chemical process and physical mixed and the water-based print ink that makes by aqueous high molecular emulsion, organic pigment, resin, surfactant and associated additives, make and do not contain volatile organic solvent in the printing ink, in printing process, workers'health is had no adverse effects, also pollution-free to atmospheric environment, also eliminate the inflammable and explosive hidden danger in workplace, improved security.
After utilizing above-mentioned reflectance coating 20 to stick on the framework, though between reflectance coating 20 edges and the framework a little gap is arranged unavoidably, and the ink lay 202 of black can effectively send light guide plate and pass the light in this gap and sponges, and to eliminate the electronic product light leak bad and reach.
As shown in Figure 3, it is liquid crystal module 30 structural representations of the use of the utility model one embodiment reflectance coating shown in Figure 2.
Liquid crystal module 30 comprises liquid crystal panel 301 backlight panels 302 of mutual butt.
Described backlight panel 302 comprises housing 321, light guide plate 322, light source 323 and reflectance coating 324.
Light guide plate 322 mounts are in housing 321.
Described light source 323 is assemblied in the housing 321 and is positioned at the side of described light guide plate 322.
Described reflectance coating 324 is attached on the described housing 321, and with a surperficial butt of described light guide plate 322.Another surperficial butt of described liquid crystal panel 301 and described light guide plate 322.
The structure of described reflectance coating 324 is identical with the structure of reflectance coating 20 shown in Figure 2, and the ink lay of reflectance coating 324 is away from described light guide plate 322.。
Among other embodiment, can also increase diffusion sheet, brightening piece etc. between described liquid crystal panel 301 and the light guide plate 302.
When light that light guide plate 322 is sent passed gap between reflectance coating 324 and the housing 321, can the be reflected black ink layer of film 324 of light absorbed, and to eliminate 30 groups of light leaks of liquid crystal module bad and reach.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
