Abstract
The utility model discloses a compound light guide plate, its characterized in that: from the top down includes MS surface course (1), PS base member layer (2), MS bottom (3) in proper order, the interior complex mode composite connection of coextrusion film is adopted to MS surface course (1), PS base member layer (2), MS bottom (3), be provided with light guide network point layer (5) that form by the laser sculpture on MS bottom (3), it arranges surface course (4) to be provided with the water chestnut mirror that adopts mould hot briquetting on MS surface course (1). The beneficial effects of the utility model are that: its cost is low than material panels such as PMMA, MS, by a wide margin reduce cost, the laser beam machining performance is good, and laser sculpture concave point is difficult for appearing carbonization, crack and sawtooth, the water expansion performance is poor, thereby avoids the light guide plate to appear absorbing water warping and lead to dark line, blackspot scheduling problem, can not produce the printing ink scheduling problem that drops in the use simultaneously.
Description
Technical field
The utility model is related to light guide plate field, more particularly, to a kind of composite light guide plate.
Background technology
With the continuous development of guide-lighting plate technique, light guide plate mesh point process technology, just turned from serigraphy to laser engraving
Become, the light guide plate produced using laser engraving halftone dot technique have distribution it is uniformly unified, it is guide-lighting evenly, and without dark line
With the advantage of spot.But in actual production, when processing light guide plate using laser engraving halftone dot technique, because laser intensity is to normal
Straightedge material, such as PS sheet materials can produce inevitably damage, it may appear that laser spots are excessively carbonized, splitting occurs in laser point edge
Seam, the phenomenon of sawtooth, so as to have a strong impact on the guide-lighting performance of light guide plate.
In addition, light guide plate is according to different using approach, selected materials also difference, it is however generally that, PS etc. it is low into
This material is used for flat lamp, illumination, advertising lamp box etc., and the high cost such as MS, PMMA material is then used for television set, flat board and shows
Show device etc..So, it is at present to adopt composite construction for reduces cost more, inexpensive 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-panel monitor.But how the composite board of low cost fits
For laser engraving site process, still solved without disclosed technical scheme at present.
Secondly, large-sized television set, flat-panel monitor can be poor because of sheet material water absorbing properties, cause water suction to produce deformation,
So as to affect the durability and guide-lighting performance of light guide plate.The A of Chinese utility model patent CN 104122618 discloses a kind of compound
Light guide plate, its intermediate layer adopts PS sheet materials using PC plate material, both sides, and the deformation problems of sheet material can be to a certain degree solved after being combined,
But because of PC prices height, and the PS sheet materials of both sides cannot meet the requirement of laser engraving site, so, it still suffers from many needs and changes
The technical problem entered.
The content of the invention
The purpose of this utility model is aiming at the deficiencies in the prior art and provides a kind of Laser Processing excellent performance, cost
Low, not hygroscopic deformation, and the composite light guide plate of the high tool laser engraving site of brightness.
In order to achieve the above object,
The technical solution adopted in the utility model is：
A kind of composite light guide plate, includes successively from top to bottom MS surface layers（1）, PS base layers（2）, MS bottoms（3）, the MS
Surface layer（1）, PS base layers（2）, MS bottoms（3）Using complex method composite joint in co-extrusion film, the MS bottoms（3）Upper setting
Have by the light directing site layer of laser engraving（5）, the MS surface layers（1）On be provided with mould heat pressure shaping water chestnut mirror row
Row surface layer（4）.
Preferably, the PS base layers（2）Thickness be the composite light guide plate gross thickness 60-96%.
Preferably, the water chestnut mirror arranges surface layer（4）In water chestnut mirror be shaped to the polygon rhombogen of V shapes.
Preferably, the corrugation pitch scope of the polygon rhombogen of described two adjacent V-arrangements is little more than or equal to 30um
In equal to 500um, the altitude range of water chestnut mirror more than or equal to 15um to be less than or equal to 150um.
Preferably, the water chestnut mirror arranges surface layer（4）In water chestnut mirror be shaped to spheroid.
Preferably, the diameter range of the spheroid is more than or equal to 0.02mm to be less than or equal to 0.5mm, institute
Water chestnut mirror spheroid altitude range is stated to be less than or equal to 0.15mm more than or equal to 0.01mm.
The beneficial effects of the utility model are：The utility model is the improvement to composite light guide plate, using the PS of low cost
Sheet material using MS sheet materials as bottom and surface layer, and is respectively arranged in bottom and surface layer and is formed by laser engraving as base layer
Light directing site layer and using mould heat pressure shaping or ejection formation prism arrangement surface layer, after this kind of technical scheme, its
That what is brought has the beneficial effect that：
1st, using PS sheet materials as base layer, its cost is low compared with the material sheet material such as PMMA, MS, and composite board can be greatly reduced
Cost.
2nd, using MS sheet materials as bottom and surface layer, its Laser Processing excellent performance is less prone to carbonization, crack and sawtooth；
Simultaneously its water swelling coefficient is low compared with PS sheet materials, in use, PS base layers can be shielded, it is to avoid light guide plate goes out
The problems such as now water suction deformation is so as to cause dark line, blackspot.
3rd, arrange using the light directing site layer of laser engraving, because of its light directing site arrangement uniformly, during use not
The problems such as ink being produced and come off, therefore there is more preferable durability and guide-lighting performance compared with serigraphy site.
The 4th, water chestnut mirror arrangement surface layer using mould heat pressure shaping or ejection formation is set, light source utilization rate can be improved, lifted
Brightness.
