Description
Technical field
The utility model relates to a kind of ultra-thin composite light guide plate.
Background technology
Current light fixture uses LED or the point/line source of other high brightness, for reducing light source dazzle or improving light source comfort level visually, diffuser plate is generally used point/line source to be diffused as the area source of brightness uniformity, and the index weighing diffusion effect is mist degree and light transmittance, both are the highest more good, but these two kinds of optical indexes are contradiction in existing technology.Conventional diffusion plate is addition diffusant in the base materials such as transparent PMMA, PC, PS, PP, by the micro-structural of diffusant and substrate surface to the refraction of light, reflect, scatter and reach light diffusion effect, general diffusant is the low transparent roughened appearance of white, the diffusant that diffuser plate that mist degree is the highest is to be added is the most or micro-structural is the most tiny, density is the highest, owing to the diffusion particle of diffusant also exists the effect blocked and diffusant and micro-structural to light, light refraction repeatedly, scattering are caused the loss of light, so the highest its light transmittance of diffuser plate of mist degree is the lowest.Therefore reflector plate, light guide plate, diffusion sheet, brightness enhancement film is needed to form on module meets the tendency.How display is made superthin structure and become technical research direction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of ultra-thin composite light guide plate.
The technical solution adopted in the utility model is:
A kind of ultra-thin composite light guide plate, it includes that light guide base plate, described light guide base plate upper surface are exiting surface, and the exiting surface of light guide base plate is provided with micro-prism structure, and the lower surface of light guide base plate is reflecting surface, and the reflecting surface of light guide base plate is provided with frosted micro-structural；Described micro-prism structure includes more than two prism bar be arrangeding in parallel, the cross section of described prism bar is isosceles triangle, the angle of the vertex angle theta of prism bar is 110-120 degree, the depth H of prism bar is 30-60 μm, described frosted micro-structural is starlight frosted structure, and the thickness of described starlight frosted structure is 80-120 μm.
Described micro-prism structure is one-body molded with light guide base plate.
The thickness of described light guide base plate is 0.6-0.9mm.
Described light guide base plate is made up of the transparent plastic of polycarbonate or poly-methacrylate fat.
The utility model uses above technical scheme, and two-sided in light guide base plate is respectively provided with special micro-structural, and the frosted micro-structural of lower surface possesses lens performance, and the micro-prism structure of upper surface has extremely large scattering process.Ultra-thin composite light guide plate of the present utility model has good light importing property and diffusivity and has high permeability, by changing the shape of micro-prism structure or frosted micro-structural and different arrangement, diffusion angle, the space of light field and Energy distribution can be adjusted, it is achieved the uniformity and the impact of light transmittance on light diffusing sheet.The utility model can combine with almag can form ultra-thin module, is the only selection of ultrathin display.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details；
Fig. 1 is the structural representation of a kind of ultra-thin composite light guide plate of the utility model；
Fig. 2 is the top view of a kind of ultra-thin composite light guide plate of the utility model.
Detailed description of the invention
As shown in Figure 1 or 2, the utility model includes light guide base plate 1, and described light guide base plate 1 upper surface is exiting surface, and the exiting surface of light guide base plate 1 is provided with micro-prism structure 2, the lower surface of light guide base plate 1 is reflecting surface, and the reflecting surface of light guide base plate 1 is provided with frosted micro-structural 3；Described micro-prism structure 2 includes more than two prism bar be arrangeding in parallel, the cross section of described prism bar is isosceles triangle, the angle of the vertex angle theta of prism bar is 110-120 degree, the depth H of prism bar is 30-60 μm, described frosted micro-structural 3 is starlight frosted structure, and the thickness of described starlight frosted structure is 80-120 μm.
Described micro-prism structure 2 is one-body molded with light guide base plate 1.
The thickness of described light guide base plate 1 is 0.6-0.9mm.
Described light guide base plate 1 is made up of the transparent plastic of polycarbonate or poly-methacrylate fat.
The utility model is guide-lighting diffusion function to be compounded in thickness only have on the panel of 0.8 millimeter, and has all done micro-structural two-sided.The frosted micro-structural 3 of bottom surface has fabulous lens performance, and spot light can import light guide base plate 1, and the light dissipated imports and uniformly spread by light source through light guide base plate 1, it is achieved that uniformly diffusion and the high light transmittance to light source.Ultra-thin composite light guide plate of the present utility model combines with almag base plate, one layer of glue-line with reflex of coating makes light guide base plate 1 have high permeability between the two, module thickness can control in the range of 1.15 millimeters, can control, within 7 millimeters, to be truly realized the effect of knife edge display plus liquid crystal panel thickness.
Ultra-thin composite light guide plate is widely used in liquid crystal display and LED illumination and imaging display system, and its major function is to make incident light fully scatter, it is achieved radiation response softer, uniform.A, it is applied to the direct-type backlight origin system that LCD TV is used, be combined with almag and there is heat resistance, dimensional stability, excellent shielding and durability so that it is light diffusion effect reaches optimum state, it is best suitable for direct-type backlight source unit, it is achieved that ultra-thin display.B, being applied to the directly-down light source system that LED illumination is used, it is not required to do light the biggest diffusion, it is only necessary to change visual effect.
