Description

Light guide plate multilayered structure

Technical field

The utility model relates to light guide plate field technologies, refer in particular to a kind of light guide plate multilayered structure.

Background technique

Light guide plate (light guide plate) is acrylic/PC plate material using optical grade, then high anti-with having Rate and the not hitech materials of extinction are penetrated, carve in the acryl plates bottom surface laser engraving of optical grade, V-type cross grid, UV screen printing technology stamps light guiding points.The light issued from lamp is drawn in optical grade acrylic using optical grade acryl plates The stop of plate surface, when light is mapped to each site, reflected light can toward all angles spread, then destroy conditioned reflex by It projects in light guide plate front.But there is the non-uniform problems of light out for existing light guide plate, to influence image quality；In addition do not add lustre to Layer and being used cooperatively for scattering layer cause emitting brightness bad.Therefore, it copes with existing light guide plate to improve, to solve above-mentioned ask Topic.

Utility model content

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of novel lead Tabula rasa multilayered structure efficiently solves existing light guide plate and goes out that light is uneven, influences the bad problem of image quality, emitting brightness.

To achieve the above object, the utility model is using following technical solution:

A kind of light guide plate multilayered structure, include from bottom to top successively fold set transparent PC layers to shield, Light-absorbing quantum layer, the Rayleigh scattering layer for influencing the light type of emergent light by optical transmission direction shine for expanded light beam Penetrate the lustre adding layer of range and the site layer for converting linear light source to area source；Multiple sites are provided on the layer of site.

As a preferred embodiment, the upper surface of the site layer is also folded is equipped with buffer layer.

As a preferred embodiment, the buffer layer is Si_xO_yOr Si_xN_yMaterial.

As a preferred embodiment, the Rayleigh scattering layer has the scattering particles of Rayleigh scattering, the scattering particles Size is less than 700nm.

As a preferred embodiment, the scattering particles is organic scattering particles or inorganic SiO₂Particle.

As a preferred embodiment, the hemispherical groove in the site.

As a preferred embodiment, the lustre adding layer is with a thickness of 160-180 μm.

As a preferred embodiment, the site thickness degree is respectively 130-150 μm.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Known to scheme:

By the setting of quantum layer, quantum material absorbability is very big, can greatly improve sensitivity, and energy conservation； The setting of Rayleigh scattering layer enables to the light type of the emergent light of the light guide plate no longer to be influenced by optical transmission direction, and equal In each to transmitting and with identical energy；The setting of lustre adding layer is used for expanded light beam range of exposures, light can be amplified, It is irradiated on entire site layer；The setting of site layer, converts area source for linear light source, to make the utility model emitting brightness Good and uniform in light emission.

For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair The utility model is described in detail.

Specific embodiment

Please refer to shown in Fig. 1, that show the specific structure of the preferred embodiment of the utility model, include by lower and On successively fold the transparent PC layer 10 to shield set, light-absorbing quantum layer 20, make the light type of emergent light not light biography Rayleigh scattering layer 30 that defeated direction influences, for the lustre adding layer 40 of expanded light beam range of exposures and for converting linear light source to The site layer 50 of area source.

The transparent PC layer 10 plays the role of protecting quantum layer 20.The setting of quantum layer 20, quantum material absorbability It is very big, sensitivity, and energy conservation can be greatly improved.

The setting of the Rayleigh scattering layer 30 enables to the light type of the emergent light of the light guide plate no longer by optical transport side To influence, and in each to transmitting and with identical energy, when Rayleigh scattering layer 30 is applied to side entering type quantum dot backlight module, The taste problem turned blue at edge can effectively be improved.Rayleigh scattering layer 30 is applied to the side entrance back mould of Conventional white LED When group, backlight illumination can also be realized in left and right and up and down direction symmetry characteristic, to further improve side entrance back module Visual angle.Rayleigh scattering layer 30 has the scattering particles of Rayleigh scattering, and the size of the scattering particles is less than 700nm.

The lustre adding layer 40 is used for expanded light beam range of exposures with a thickness of 160-180 μm, light can be amplified, irradiation In on entire site layer 50.

The site 50 thickness of layer are respectively 130-150 μm, multiple sites 51 are provided on site layer 50, in the present embodiment In, the hemispherical groove in site 51, site layer 50 is mainly used for converting area source for linear light source.The upper surface of site layer 50 is also It is folded to be equipped with buffer layer 60, it is used to protect site layer 50, in the present embodiment, buffer layer 60 is Si_xO_yOr Si_xN_yMaterial.
