Can be good the characteristics of.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the utility model light guide plate；
Fig. 2 is biconial prism structure schematic diagram in the utility model light guide plate.
Embodiment
As shown in figure 1, the utility model provides a kind of light guide plate with biconial prism structure, the light guide plate is
Parallel light guide plate, it is characterised in that including：
The reflection basic unit 1 being mixed by polycarbonate plastic and reflecting material particle, the reflection substrate surface are formed
Biconial prism structure 2.
Wherein polycarbonate plastic is mixed and made into reflection basic unit with reflecting material particle, and reflecting material particle can be tentatively right
Light is scattered, and first time scattering is carried out to light, and wherein reflecting material particle is not the approach being uniquely scattered to light, because
This amount when adding reflecting material particle is smaller relative to the light guide plate only by reflecting material particle, due to reflecting material with
The fundamental material property of basic unit is completely different, and base material is more beneficial in the case where adding less reflecting material particle
Stability so as to postponing service life and improve stability.
As shown in Fig. 2 wherein biconial prism structure passes through cutting twice respectively on described two axial directions, make the bipyramid
Shape prism structure has a top surface 21 and two groups of corresponding sides, including first group of side 22 and second group of side 23, should
Top surface 21 is a quadratic surface；Biconial prism structure is second approach that the utility model light guide plate is scattered to light,
Wherein by the way that the structure Jing Guo cutting twice can fully utilize the light of all angles respectively on two axial directions, so as to improve light
Utilization rate.
The surface of biconial prism structure 2 forms uniform nano-pore；Nano-pore is relative to biconial prism structure
Structure on the yardstick of smaller several orders of magnitude, has further refined the light scattering on biconial prism structure surface, has been this reality
The three approach being scattered with light guide plate to light.
The nano-pore is formed by electron beam exposure, nano impression or deep-UV lithography.
Further, in addition in the reflection basic unit Anti-reflective coating formed.Anti-reflective coating can carry out further mistake to light
Filter, prevent from producing diffraction or interference mutually between light, be so advantageous to improve the stability of the light extraction of light guide plate.
Further, sticky protective layer made of pure PET, the viscosity protection are covered with the surface of the Anti-reflective coating
Layer is formed on the Anti-reflective coating surface by coating method.
