Description

1320865 V. INSTRUCTION DESCRIPTION (1) - [Technical Field to Be Invented] - The present invention relates to a light source homogenizing structure of a backlight module, and more particularly to a light source homogenizing structure applied to a direct type backlight module. [Prior Art] Press, generally used in the liquid crystal display of the information device, can choose to use the direct-lit or edge-lit backlight module architecture according to the actual design requirements; as shown in the first figure, it is always down. The basic structure diagram of the backlight module structure, the overall backlight module is composed of a reflector 10, a plurality of light sources 20, a diffusion plate 30, a number of f optical films 40, and a liquid crystal. The panel 50; wherein, each of the light sources 20k can be a straight strip or a U-shaped or other continuously bent tube and laid between the reflector 10 and the diffuser 30 at an appropriate distance; It is also common that the optical film 40 between the diffusion plate 30 and the liquid crystal panel 50 can be matched by a diffusion sheet of 1.1 to 3 pieces, a brightness enhancement piece of 0 to 2 pieces, a reflection type polarizer of 0 to 1 piece, and the like. The function of the light is to form and diffuse through the light, so as to improve the phenomenon that the light source and the dark band are formed on the liquid crystal module because no light is generated at the interval between the light sources. Moreover, since the effect of the diffusing plate 30 is only to uniformly disperse the light passing through, the effect of improving the phenomenon of the bright and dark regions of the liquid crystal module is limited, because some of the backlight modules deliberately lengthen the light source 20 and The gap between the diffusion plates 30 is expected to expand the range of the light sources 20 into the diffusion plate 30 to reduce the dark zone; however, such a structural design not only has a limited effect, but also increases the thickness of the backlight module. And the thinner and thinner LCD module

1320865 V. Description of the invention (2) The original intention of the invention is contrary to the original method of using the film source to determine the relative density of the film, in order to present the hair in the Ming Dynasty, to improve the film, which should be equalized, the angle before the film twice More clearly, the capacity of the light source, its liquid crystal, the liquid structure of each light guide luminosity or the light-guided active dark-band backlight module produced by the liquid crystal display panel is not obvious, its main source and optical parts The light source of the base illuminator for the depth of the junction to be diffused and active by the light member is to be homogenized by a diaphragm or a source, by means of means, More uniformity of the light and the optical side of the group are eliminated from the optical structure to eliminate the effective and effective structure." The optical plate body is represented by the liquid crystal structure source, and the optical light is set to make the light source solve the distribution of the light source. That is, the optical panel is disposed between the needle panel, the same effect diaphragm, and the passage of the plurality of plate sources, and the backlight is used to illuminate the liquid crystal. The light of the dim light module of the light emitted by the light of the light surface shows that the structure of the light is different from that of the light body. At least the zone is obvious. [Embodiment] In order to enable the reviewing committee to understand the structural composition of the present invention and the overall operation The method is as follows: The light source homogenizing structure of the backlight module is mainly provided with a light source homogenizing structure between the light source of the liquid crystal display and the related optical film, which is mainly composed of an optical a plate body, and the optical plate body is composed of a plurality of light guiding members disposed on each side of the light source and the optical film, the light guiding member

Before the sixth page, the angle or the deep film, the depth of each of the polygonal pyramids of the light guide structure is equal to the depth of the 1 m surface or may be if the protrusion or protrusion is formed, the two folds (A) In the manner of the display, the diffusion strip structure Ρ Μ Μ A ( 矽 (Si 02) or the structure can be formed on the entire optical line. The basic composition frame, and the reverse can be generally 0 to 2 pieces of the optical 1320865 V. DESCRIPTION OF THE INVENTION (3) The structure is formed by a structure of different density which protrudes or protrudes from the surface of the optical plate body, and the light of the light source is incident on the optical film. The light source is homogenized to make the light passed. At least through the diffusion, the light of the light source can be distributed more effectively. In a specific implementation, as shown in the second figure, the light source homogenizing member 6 1 can be constructed by a plurality of protrusions or pits as shown in the figure. In an embodiment, the distance between the light guide members is less than m, and each light guide member protrudes or protrudes from the height of the optical plate body plate by less than or equal to 0.5 mm, and each light guide member 61 has a protruding or concave groove. The structure is constructed, and the groove is provided for the surface of the optical plate 60 The two refracting portions 6 2 can be formed at different angles, as shown in the third figure or as shown in the third figure (B), which can be formed with different depths to define the protruding structure or the pit structure. It is designed to be a structural form of the extension plate body 60, and can all act on the light passing through; further, the material of the optical plate body 60 can be transparent or made of a transparent plastic material such as PC (polycarbonate) or a white mist-like strip made of a diffusing agent such as titanium dioxide (T i 0 2 ) or the like, in the embodiment shown in the fourth figure, a structure of a liquid crystal display, The inner surface of a reflector 10 is uniformly provided with a light source 20. The opening of the mask 10 is sequentially provided with an optical plate body 60 (material of the diffusion plate), and a diffusion sheet of 1 to 3 pieces, a brightness enhancement sheet, 0 to 1 piece of reflective polarizer, etc.
