Abstract
The utility model relates to the optical field, in particular to an optical membrane of a four-prism microstructure, which comprises a substrate and a four-prism lens unit. The optical membrane is characterized in that the substrate comprises a first surface and a second surface, the four-prism lens unit consists of a plurality of four-prism lenses, each four-prism lens and at least another one four-prism lens are arranged adjacent to each other on the first surface of the substrate; the bottom surface of each four-prism lens is a square, the four-prism lenses and the first surface of the substrate form identical vertical heights; each four-prism lens comprises a first inclined surface, a second inclined surface, a third inclined surface and a fourth inclined surface, and the four inclined surfaces are four isosceles triangles with identical sizes. Compared with the prior art, the utility model not only saves the cost and the energy, but also simplifies the process flow of the backlight manufacturer, improves the productivity, and reduces the rejection rate.
Description
[technical field]
The utility model relates to optical field, a kind of specifically blooming of four prism microstructure.
[background technology]
The blooming of present domestic use is to utilize optical total-reflection and refraction effect mostly, and in-plane scatter light is carried out to a certain degree polymerization, and its brightness effects is poor, and the light of total reflection is not recycled, and energy resource consumption is big.
[summary of the invention]
The purpose of this utility model is to have overcome the deficiencies in the prior art, thereby providing a kind of has on a slice blooming the optically focused on the realization level and vertical direction and saves cost, thereby the technological process of having simplified backlight producer has improved throughput rate, the rate of reducing the number of rejects and seconds, and has the blooming of a kind of four prism microstructure of the energy of saving 50% under equal effect.
Designed a kind of blooming of four prism microstructure to achieve these goals, comprised base material and rectangular pyramid mirror unit composition, it is characterized in that: described base material comprises a first surface and a second surface;
Described rectangular pyramid mirror unit is formed and is made up of several several rectangular pyramid mirrors, and each rectangular pyramid mirror at least with the first surface of adjacent arrangement of another rectangular pyramid mirror and described base material on; The bottom surface of each rectangular pyramid mirror is that its length of side of square is 25～70 μ m, and has identical vertical height between the first surface of each rectangular pyramid mirror and base material, and it highly is is 10～50 μ m highly; Each rectangular pyramid mirror comprises one first dip plane, second dip plane, the 3rd dip plane and one the 4th dip plane, and four dip plane are four isosceles triangles that size is equal, and the inboard drift angle angle of each isosceles triangle is 60～110 °.
The utility model is compared with prior art, not only has the saving cost, energy savings, and simplified the technological process of producer backlight, and improved throughput rate, reduced rejection rate.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3,1 is base material, and 2 is first surface, and 3 is second surface, and 4 is the rectangular pyramid mirror unit, and 5 is first dip plane, and 6 is second dip plane, and 7 is the 3rd dip plane, and 8 is the 4th dip plane.
[embodiment]
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model is a kind of blooming of four prism microstructure, comprises a base material 1 and a rectangular pyramid mirror unit 4; This basic unit comprises a first surface 2 and a second surface 3, can wear for pipeline and penetrate process.The first surface 2 of this base material 1 is as the light emitting side of this base material 1, and second surface 3 is as the light light incident side of this base material 1, and vice versa.This rectangular pyramid mirror unit 4 is made up of several rectangular pyramid mirrors, each rectangular pyramid mirror at least with the first surface 2 of adjacent arrangement of another rectangular pyramid mirror and described base material 1 on, have identical vertical height between the first surface 2 of each rectangular pyramid mirror and base material 1, it highly is 10～50 μ m.This rectangular pyramid mirror unit 4 can be positioned at the light emitting side of this base material 1, also can be positioned at the light incident side of light.Each rectangular pyramid mirror is made up of one first dip plane 5, one second dip plane 6, the 3rd dip plane 7 and one the 4th dip plane 8, four dip plane are four isosceles triangles that size is equal, the inboard drift angle angle of each isosceles triangle is 60～110 °, and at least one in four dip plane is a crooked curved surface that extends, but the wavy bending of formation rule is to produce curved transition, and then be able to produce light refraction at two-dimensional directional at least, so that produce good optically focused phenomenon, and has energy-conservation effect.
