Problems solved by technology

[0013] Most of the above-mentioned concentrating sheets with a light-diffusing layer make the finished concentrating sheet further processed to make a rough surface layer at the bottom, which is more labor-intensive.
And the side of the concentrating sheet with a plurality of parallel prism columns is relatively smooth, if there is a defect, it is easier to be found, and it is considered as a defective product

Embodiment Construction

[0025] Please refer to the accompanying drawings and embodiments for the purpose and effect of the present invention, and the detailed description is as follows.

[0026] see Figure 5 , 6 , 7 shown. The light-diffusing and concentrating sheet of the present invention is used to reduce the light dispersion phenomenon of the prism column and the probability of moiré, and helps to improve the production qualification rate. The light-diffusing and concentrating sheet 30 of the embodiment of the present invention includes: a substrate 31 through which light can pass. A surface of the substrate 31 includes a plurality of longitudinally arranged elongated prism columns 32 and a plurality of elongated rough diffusion surfaces 33; at least two adjacent prism columns 32 have elongated rough diffusion surfaces 33; Each prism column 32 has a ridgeline 321, a first side 322, and a second side 323 respectively; the ridgeline 321 is placed at the highest position of the prism column 32; ...

Abstract

The invention relates to a diffusion condenser, wherein, a long strip rough diffusion side is arranged between two closed prism pillars. The mixing of the ray diffused from the diffusion face between two prism pillars and the ray emitted from the prism pillar can effectively reduce light color diffusion phenomenon and strip in pulverization of prism pillars, reduce occurrence of overlapped trace and increase producing qualification rate of the condenser. The base material, a plurality of long strip prism pillars of longitudinal arrangement and rough diffusion side of long strip shape are forming in one piece so as to be made easily.

Description

technical field [0001] The present invention relates to a light-condensing sheet, especially to a backlight system for a liquid crystal display (LCD, LiquidCrystal Display) or other required diffusion-condensing sheets. Background technique [0002] see figure 1 shown. The backlight system of a general liquid crystal display includes a cold cathode lamp (CCFL) 11, a light guide plate (LGP) 12, a bottom diffuser (Bottom diffuser) 13, a light concentrating sheet (Prismsheet) 14, an upper diffuser (Top diffuser) 15 and Reflector (Reflector) 16 is formed. [0003] see figure 2 shown. The known condensing sheet 14 is composed of a plurality of triangular prism rods (Prism rod) 141 and a substrate (Substrate) 142 arranged in parallel longitudinally. The prism column 141 is combined with one side of the substrate 142 . The height and width of each prism column 141 are the same, and the height of the ridge line of the prism column 141 is constant, the trend is a straight line...
