New Description: 【New Technology Fields】 This is a diffusion concentrating sheet for LCD backlight modules, especially a kind of diffusing sheet and concentrating sheet to achieve concentrating and averaging effects at the same time. The diffusing concentrating sheet of the LCD backlight module. [Prior Art] Please refer to FIG. 1 , which is an optical film matching method in the conventional backlight module 6 , which mainly includes a light guide plate 6 on the surface of the light guide plate 61. The sheet 62, the concentrating sheet 63 and the upper diffusing sheet 64, when the light source enters the light guiding light • #1, diffuses the light source through the lower diffusing sheet 62 to improve the uniformity of the light beam, otherwise the user may not distribute the brightness of the screen due to the brightness of the screen. I feel uncomfortable and concentrate the light to the center to increase the brightness of the center, and a plurality of sheets m can be used to increase the brightness, and the upper diffusion sheet 64 prevents the 稜鏡 structure on the condensing sheet 63 from scratching the liquid crystal glass and alleviating Pixels Moire generated by the condensing sheet 63 and the pixels of the liquid crystal glass. Although the conventional backlight module 6 can be used for the uniform light and the condensing effect by using the upper diffusion sheet 64, the lower diffusion sheet 62, and the condensing sheet 63, it lacks the following drawbacks in application. The diffusion sheet 64, the lower diffusion sheet 62, and the condensing sheet 63 on the backlight module 6 are separately produced, resulting in a relatively high manufacturing cost. 2. When the conventional backlight module 6 is assembled, the lower diffusion sheet 62 and the expansion sheet 64 on the concentrating sheet 63 are sequentially placed on the light guide plate 6丨, so that it takes a long time for the group to work. It does not meet economic benefits. It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer's and needs to be improved. The shortcomings of the field and the creator of the above-mentioned conventional backlight module are improved and innovated, and after years of painstaking research, they finally succeeded in research and development. 5 M346016 Completed the diffusion concentrating sheet of this LCD backlight module. [New content] The purpose of this creation is to provide a kind of optical film with a diffusing film and a concentrating film. Only one optical film can simultaneously have both optical functions of diffusion and concentrating, and also reduce the function of M〇ire. The diffusing concentrating sheet of the LCD backlight module. The second objective of the present invention is to provide a diffused concentrating sheet for an LCD backlight module which can improve the optical performance and can reduce the cost of the invention. The diffusing concentrating sheet of the LCD backlight module capable of achieving the above novel object comprises a substrate which is made of a light transmissive material to make it transparent, and has a surface and a surface The surface is formed on the first surface of the substrate with a powder: f layer & a plurality of diffusion particles are doped into the substrate or the light collecting layer, so that the diffusion n is earlier than the substrate or the light collecting layer; When the light enters the substrate, it will be expanded: light: Π refraction, and even sentence scattering, in order to achieve the purpose of homogenization, the average sentence scatters M d to the convergence of the Μ layer to increase the brightness of the light.
