Description
Technical field
The present invention relates to light guide plate field, especially relate to a kind of composite light guide plate.
Background technology
Along with the development of light guide plate technology, light guide plate mesh point process technology, just turned to laser engraving by silk screen printing
Becoming, the light guide plate using laser engraving halftone dot technique to produce has distribution uniformly unified, leaded light and evenly, and does not has dark stricture of vagina
Advantage with speckle.But in actual production, when using laser engraving halftone dot technique processing light guide plate, owing to laser intensity is to often
Straightedge material, as PS sheet material etc. can produce inevitably damage, it may appear that splitting occur in the excessive carbonization of laser spots, laser spots edge
Seam, the phenomenon of sawtooth, thus have a strong impact on the guide-lighting performance of light guide plate.
It addition, light guide plate is different according to the approach of use, selected material the most difference, it is however generally that, the low one-tenth such as PS
This material is used for flat lamp, illumination, advertising lamp box etc., and high cost material is then used for television set, flat board shows for MS, PMMA etc.
Show device etc..So, in order to reduce cost, use composite construction at present more, low cost sheet material and high cost sheet material are combined, reduce
While cost, its guide-lighting performance remains to meet the use of television set, flat faced display.But how the composite board of low cost fits
For the laser engraving site course of processing, the most still solved without disclosed technical scheme.
Secondly, large-sized television set, flat faced display can be poor because of sheet material water absorbing properties, cause water suction to produce deformation,
Thus affect the durability of light guide plate and guide-lighting performance.Chinese invention patent CN 104122618 A discloses a kind of composite light guiding
Plate, its intermediate layer uses PC sheet material, both sides to use PS sheet material, compound after can to a certain degree solve the deformation problems of sheet material, but because of
PC price is high, and the PS sheet material of both sides cannot meet the requirement of laser engraving site, so, it still suffers from what many needs improved
Technical problem.
Summary of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art and provides a kind of Laser Processing excellent performance, low cost, no
Hygroscopic deformation, and the composite light guide plate having laser engraving site that brightness is high.
In order to achieve the above object,
The technical solution used in the present invention is:
A kind of composite light guide plate, includes MS surface layer (1), PS base layer (2), MS bottom (3), described MS surface layer the most successively
(1), PS base layer (2), MS bottom (3) use complex method composite joint in co-extrusion film, described MS bottom (3) is provided with by
Guide-lighting site layer (5) of laser engraving, described MS surface layer (1) is provided with the Pedicellus et Pericarpium Trapae mirror arrangement plane of mould heat pressure molding
Layer (4).
Preferably, the 60-96% that thickness is described composite light guide plate gross thickness of described PS base layer (2).
Preferably, the Pedicellus et Pericarpium Trapae mirror in described Pedicellus et Pericarpium Trapae mirror arrangement surface layer (4) is shaped to the polygon rhombogen of V shape.
Preferably, the corrugation pitch scope of the described two polygon rhombogens of adjacent V-arrangement is for little more than or equal to 30um
In equal to 500um, the altitude range of Pedicellus et Pericarpium Trapae mirror for being less than or equal to 150um more than or equal to 15um.
Preferably, the Pedicellus et Pericarpium Trapae mirror in described Pedicellus et Pericarpium Trapae mirror arrangement surface layer (4) is shaped to spheroid.
Preferably, the diameter range of described spheroid for being less than or equal to 0.5mm more than or equal to 0.02mm, institute
State Pedicellus et Pericarpium Trapae mirror spheroid altitude range for being less than or equal to 0.15mm more than or equal to 0.01mm.
The invention has the beneficial effects as follows: the present invention is the improvement to composite light guide plate, use the PS sheet material conduct of low cost
Base layer, employing MS sheet material is as bottom and surface layer, and is respectively arranged by the guide-lighting net of laser engraving at bottom and surface layer
Point layer and employing mould heat pressure molding or the prism arrangement surface layer of ejection formation, after using this kind of technical scheme, what it brought has
Benefit effect is:
1, using PS sheet material as base layer, its cost is low compared with material sheet materials such as PMMA, MS, and composite board can be greatly reduced
This.
2, using MS sheet material as bottom and surface layer, it laser machines excellent performance, is difficult to carbonization, crack and sawtooth occur；
Its imbibition coefficient is low compared with PS sheet material simultaneously, in use, can shield PS base layer, it is to avoid light guide plate goes out
Now water suction deforms thus causes the problems such as dark stricture of vagina, black speck.
3, the guide-lighting site layer of employing laser engraving is set, because its guide-lighting site is arranged uniformly, during use not
The problems such as ink comes off can be produced, therefore relatively silk screen printing site has more preferable durability and guide-lighting performance.
4, the Pedicellus et Pericarpium Trapae mirror arrangement surface layer of employing mould heat pressure molding or ejection formation is set, light source utilization rate, lifting can be improved
Brightness.
