摘要： An optical diffusion plate applied for a direct-type backlight module and its manufacturing method are proposed complied with the present invention. By using the extrution technique, an extruder is used to extrude an optical diffusion plate. In case the material of the optical diffusion plate is changed, the texture of the roller should also be changed so that a prism array with a vertex angle corresponding to the refractive index of the material can be formed on the diffusion plate. Thereby, via the refractive index and the angle of the prism structure, the plate having a saw structure can change the propagation directions of the diffused light beams so as to focus the light beams, reduce the loss of the light and enhance the brightness. Besides, by disposing a one- or two-dimensional structure on the optical diffusion plate, the present invention needn't use the horizontal and vertical prism sheets simultaneously.

摘要： A structure of direct type backlight module with high uniform emitting light explores a design of lenticular lens of diffusing plate. The lenticular lens is against the central location of light source, where the light of lamp is scattered and the curvature of said lenticular lens far away light source is enlarged, then to reduce the scatter effect and achieve uniformity. The other lenticular lens also can be designed for light location and distance. Each lenticular lens is against light location, and incident light can be reflected through the angle of microstructure surface at the entrance facet, but farther location can be resulted in total refraction due to large inclined angle, and diminishing the transmission light of light source then influencing the uniformity, finally reducing total reflection of wide angle.

摘要： A diffusion sheet structure in the direct type backlight module with anti-UV rays function and its manufacturing method discloses a diffusion sheet in the backlight module applied to TFT-LCD TV, and plural layer of the diffusion sheet made by a method of a multi-layer co-extrusion. The diffusion sheet advocates that while producing diffusion layer, at least a ultra-violet rays absorption layer set on the surface of diffusion layer at the same time to achieve insulating ultra-violet rays directly irradiated on the diffusion sheet and to avoid yellow and pyrolysis phenomenon occurred on the diffusion sheet. These results in avoiding the deviation caused from color temperature and chromaticity coordinate of TFT-LCD TV because of yellow diffusion sheet, then to achieve the purpose of improving product quality and materials lifespan.
