Light guide plate is one of key fitment in backlight, and the molding mode of light guide plate mainly has ejection formation and sheet material to cut out
Two kinds of type is cut into, the material used in it mainly has PC and PMMA, and whether ejection formation or sheet material cut shaping, used in it
Material is all single, otherwise it is PC, otherwise it is PMMA.
The advantages such as the specific high transmittances of PMMA (i.e. brightness is high), scratch resistance, but more crisp, non-refractory；PC has tough
Advantages such as the good, high temperature resistant of property, but transmitance is more slightly lower than PMMA, compared to PMMA not scratch resistances.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of light guide plate and backlight.The light guide plate
Using coextrusion forming process by two kinds of materials of PC and PMMA make together with form integral double-decker, light guide plate was both possessed
The PMMA performance such as high, wear-resisting, also possesses the performances such as the flexible of PC, high temperature resistant, and micro-structural of the light guide plate in the later stage is processed
During also there is more preferable mouldability.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of light guide plate, including relative exiting surface and light guiding surface, and four sides, one in four sides
For incidence surface, the light guide plate forms the integral double-decker of PC layers and PMMA layers using coextrusion forming process, wherein, it is described to lead
Smooth surface is in PC layers, and the exiting surface is in PMMA layers.
Further, guide-lighting micro-structural is provided with the light guiding surface.
Further, the guide-lighting micro-structural is V-shaped groove or concavo-convex light directing site.
Further, highlighted micro-structural is provided with the exiting surface.
Further, the highlighted micro-structural is V-shaped groove or concavo-convex highlighted site.
Further, stiffened coating is coated with the exiting surface.
A kind of backlight, including above-mentioned light guide plate.
The utility model has the advantages that：The light guide plate uses coextrusion forming process by two kinds of materials of PC and PMMA
Making forms integral double-decker together, the performance such as high, wear-resisting for making light guide plate both possess PMMA, also possesses the soft of PC
The performances such as tough, high temperature resistant, the light guide plate also have more preferable mouldability in the micro-structural process in later stage.
