Abstract
The utility model discloses compound two-in-one expansion type diffuser plate in a kind of mould comprising has the foaming layer of composite molding and the diffusion layer positioned at foaming layer upper surface in mould, which has a plurality of expanded particles；The diffusion layer includes PS substrate and a plurality of diffusion particles for being mixed in PS substrate.Whereby, by the way that expanded particle is added in diffuser plate, PS dosage can be not only reduced under the same volume of diffuser plate, mitigated diffuser plate weight, reduced cost；Diffuser plate refractive index can be improved in combination with diffusion particle, to improve the diffusion effect of diffuser plate, the whole injection improved to light and diffusion effect increase brightness.
Description
Technical field
The utility model relates to optics plate field technology, compound two-in-one expansion type diffusion in a kind of mould is referred in particular to
Plate.
Background technique
The research of diffuser plate now is mainly in a liquid crystal display.In a liquid crystal display, liquid crystal display panel itself does not have hair
Light function needs to realize display function by configuring backlight source module below liquid crystal display panel to provide light source.Diffuser plate is straight
Key part in following formula LED backlight module part, its main function are that point light source or linear light source diffusion are become uniform face
Light source, and the direction of propagation efficiency of light energy utilization for being parallel to light can be improved, to improve light extraction efficiency and outgoing light homogeneity, reach excellent
The purpose that matter is shown.As increasingly fierceness, the backlight product designed of market competition are most important for producer.It is existing
The generally existing weight of diffuser plate it is larger, refringence causes diffusion effect bad.Therefore, existing diffuser plate should be changed
Into to solve the above problems.
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 multiple in a kind of mould
Two-in-one expansion type diffuser plate is closed, by the way that expanded particle is added in diffuser plate, mitigates diffuser plate weight, reduces cost；Together
When combine diffusion particle diffuser plate refractive index can be improved, to improve the diffusion effect of diffuser plate.
To achieve the above object, the utility model is using following technical solution:
Compound two-in-one expansion type diffuser plate in a kind of mould includes the foaming layer of composite molding and to be located at foaming layer in mould
The diffusion layer of upper surface, the foaming layer have a plurality of expanded particles；The diffusion layer includes PS substrate and is mixed in PS substrate
In a plurality of diffusion particles.
As a preferred embodiment: the diffusion particle is one of PC, PET, PE, PMMA, PS, AS and PP or two
Kind or more diffusant.
As a preferred embodiment: the diffusion particle is glass microballoon or organosilicon microballon.
As a preferred embodiment: the foaming layer includes PS substrate and a plurality of foaming grains for being mixed in PS substrate
Son.
As a preferred embodiment: the expanded particle is AC foaming agent.As a preferred embodiment: on the diffusion layer
Surface is provided with the lines of refraction for improving diffuser plate crocking resistance and light, reflecting properties.
As a preferred embodiment: the foaming layer is expanded polypropylene material.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Scheme can not only reduce PS dosage it is found that by the way that expanded particle is added in diffuser plate under the same volume of diffuser plate, mitigate
Diffuser plate weight, reduces cost；Diffuser plate refractive index can be improved in combination with diffusion particle, to improve the diffusion of diffuser plate
Effect, the whole injection improved to light and diffusion effect, increase brightness.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
It is described in detail.
Detailed description of the invention
Fig. 1 is the diffuser plate layer structure schematic diagram of the utility model.
Description of drawing identification:
10, foaming layer 11, PS substrate
12, expanded particle 20, diffusion layer
21, PS substrate 22, diffusion particle
23, lines.
Specific embodiment
The utility model is as shown in Figure 1, compound two-in-one expansion type diffuser plate in a kind of mould, including composite molding in mould
Foaming layer 10 and diffusion layer 20 positioned at 10 upper surface of foaming layer, in which:
The foaming layer 10 has a plurality of expanded particles 12, by PS substrate 11 and a plurality of hairs being mixed in PS substrate
Bubble particle 12 forms, and expanded particle 12 is AC foaming agent, which may be implemented physical blowing；Also, the foaming layer 10
It can be foamed polypropylene material matter (EPS) that expanded polypropylene material inherently has expanded particle 12.
The diffusion layer 20 includes PS substrate 21 and a plurality of diffusion particles 22 for being mixed in PS substrate 21, the diffusion grain
Son 22 is one or more of PC, PET, PE, PMMA, PS, AS and PP diffusant, wherein AS plastic fusing point and PS material
Expect that fusing point is close, but refractive index is different, different refractive index can be formed in this way, to improve diffusion effect；And in the diffusion
20 upper surface of layer are provided with refraction for improving diffuser plate crocking resistance and light, reflecting properties (because lines is by low beam
Near pearl) lines 23, and the lines 23 can also reduce material utilization amount.
The design focal point of the utility model is, not only can be in diffuser plate by the way that expanded particle is added in diffuser plate
PS dosage is reduced under same volume, mitigates diffuser plate weight, reduces cost；Diffuser plate folding can be improved in combination with diffusion particle
Rate is penetrated, to improve the diffusion effect of diffuser plate, the whole injection improved to light and diffusion effect increase brightness.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, thus it is all according to the technical essence of the utility model any trickle amendment made to the above embodiment, equivalent change
Change and modify, is still within the scope of the technical solutions of the present invention.
