INSTRUCTIONS: [Technical Field] The present invention relates to an improvement of a support column structure of a backlight module, and more particularly to a support column for a backlight module to be supported by a diffusion plate, which is mainly made of glass material. Thereby, the glass support column has good light transmission, reflection and refraction, and achieves the effect of effectively eliminating the formation of dark spots at the contact between the support column and the diffusion plate. [Prior Art] Liquid crystal display (LCD) with no radiation and light, thin, high brightness and low power consumption has been widely used in multimedia products such as computers, mobile phones, digital cameras, etc. The technology of the display is constantly updated, and its function and performance have been innovating and improving, so that the liquid crystal display has been improved in terms of color, brightness, uniformity of illumination and manipulation. The liquid crystal display is required to provide the f-side light source of the liquid crystal panel by the backlight module, so that the information of the back surface of the liquid crystal panel can be displayed, and it is an indispensable component in the liquid crystal display, so the backlight module is The luminous efficiency of the liquid crystal has great influence. When the backlight module itself has excellent luminous efficiency, it can not only provide the brightness of the liquid crystal display, but also provide design and manufacturing of other components in the liquid crystal display. When the luminous efficiency of the group itself is not good, the 'source limit' that can be provided often limits the brightness performance of the liquid crystal display product. The backlight module can be divided into a side type backlight module and a direct type backlight module according to the manner in which the internal light source is set up. For the case of the direct type backlight module (6), It is attached to a back plate (61) on 200837446 to fix a light source body (62) such as a light-emitting diode or a cold cathode fluorescent tube, and is similar to the light-emitting body (62) of a light-emitting diode or the like. The point source emits light. If the distance between the light source body (62) and the diffuser plate (63) of the light emitting diode is too close, there is a possibility that the light cannot be uniformly diffused, and a bright spot is generated on the diffusing plate. In order to make the light distribution of the light source body (62) to the diffuser plate (63) uniform, it is necessary to maintain a certain distance between the diffuser plate (63) and the light source body (62) so that the light source body (62) The illumination range between the two can cover each other. In the present invention, the direct-lit backlight module (6) supports the light source body (62) and the diffusion plate (63) at a certain distance between the light source body (62). A support member (64) is fixed on the back plate (61) for corresponding support on the back plate (61) and the light source The upper diffusing plate (63) of (62), wherein the light emitted from the light source body (62) can be uniformly distributed and irradiated onto the diffusing plate (63), and then folded outward through the diffusing plate (63). Diffusion is carried out, and then a plurality of brightness enhancing films (65) attached to the diffusion plate (63) are used to increase the brightness of the light emitted from the diffusion plate (63), and the brightness enhancement film is used. (65) is arranged to hide the light source body (62) when the light source is emitted, the light cannot be reflected at the contact of the support member (64) and the diffusion plate (63), and the diffusion plate (63) and the support member (64) The dark spot is generated at the junction; however, although the dark spots generated by the support member (64) on the diffusion plate (63) can be effectively achieved by the arrangement of the plurality of brightness enhancement films (65), The price of the bright film (65) is quite expensive, so it is caused by the lack of increase in the production cost of the direct type backlight module (6), which is not conducive to the manufacture of the seller, and conversely, if the layer of the brightness enhancement film (65) is to be used The number reduction 'is caused the problem of the dark spot of the support member (64) to be re-generated, so that the relevant manufacturers are trying to reduce the brightness Under the consideration of the number of layers in (65) and the elimination of the formation of shadows by the support member (64), many research and developments are carried out, such as the "backlight module and its support member" of the publication No. 1254175, which includes: 6 200837446 Plate: tube suitable =: mold package: 'The backlight module has - expansion ^, has a plurality of bearing portions; and a plurality of arcs:: wide upper 'the fixed member has a - support portion to shape and the bearing Part 2: support = abutting on the diffuser plate, the arcs are transparent or white into a solid willow tube' and the support member is provided with a "backlight module and its support member" No. _040, a lamp phase Having an opening to expose the bottom of the light box; at least one light source disposed in the light box; a plate disposed at the opening of the light box; and a cover member abutting against the bottom of the light box Between the diffusing plates, wherein the material of the f is transparent, that is, the surface of the supporting member is provided with a light expansion layer, and the light diffusion layer is adapted to reflect part of the light emitted by the light source. And the light ray that is reflected by the light diffusion layer penetrates the light diffusion layer〃 然 ^ The design of the "Backlight Module and Its Support" of the Announcement No. 1254175 and the "Backlight Module and Its Support" of the Announcement No. M3G2G4G, although made of transparent or white material Supporting column, or further providing a light diffusion layer on the surface of the support column of the transparent or white material in order to improve the occurrence of dark spots at the contact between the expansion board and the branch column, but in practice, the light penetrates the support column However, only the support column produces a light-transmitting effect, which results in a poor effect of improving the formation of dark spots, or a complicated shape, and a lack of molding. Therefore, the present inventors have in view of the fact that the existing backlight module and its supporting member are easy to produce a dark spot in the contact portion of the diffusing plate supported by the system, and it is supported by the manufacturing and design experience and knowledge of the related field for many years. Thanks to the development and improvement of the support and update of the backlight module, it is expected to improve the lack of dark spots. SUMMARY OF THE INVENTION The present invention relates to the improvement of the support column structure of a backlight module, in order to effectively improve the branching and diffusion of the top diffusion plate in the back-up group, and the contact portion is easily diffused due to poor illumination.
