New Description: [New Technology Field] This creation is about an edge-lit backlight module, especially for an edge-lit backlight module that provides a liquid crystal display source. [Prior Art] In recent years, the conventional cathode ray tube display (commonly known as CRT display) has been gradually replaced by a liquid crystal display. The main reason is that the radiation amount of the liquid crystal display is smaller than the CRT age n, and the liquid crystal display! The manufacturing cost in the year of money is also significantly reduced. In general, the liquid crystal display includes a backlight module and a liquid crystal panel. The main part of the liquid crystal display is the one used for the liquid crystal display. Nowadays, the most common _light-type backlight mold company is composed of silk, light guide plate, reflective sheet, diffuser film and brightness enhancement film, which has the advantages of light weight, thin shape, narrow frame and low material consumption. . However, the edge-light type structure is such that the light source is placed on the side of the light guide plate so that the light that is incident on the light guide plate extends across the entire light guide plate, and the brightness is rapidly attenuated as the distance of the stage is increased. Therefore, this design is better than the liquid crystal display under the 18 phase, and there are few large-size liquid crystal displays. In order to make the edge-light backing wire group smash in the large-scale nuclear crystal display (4), the patent has disclosed a plurality of side-light types. The backlight modules are arranged in parallel and spaced on the same plane, so that they can be thinner than the large-size crystal display, and do not increase the thickness of the direct-lit backlight module: M368093 to achieve thinning. Referring to FIG. 1 , FIG. 1 is a schematic diagram of an edge-lit backlight module of the Republic of China Patent No. 1247551. The edge-lit backlight module (1) includes a plurality of light guide plates (11) and a light source (12). ), a reflecting plate (13), a diffusion film (15), and a brightness enhancing film (16). The light guide plate (11) is a wedge body and has a light exit surface (11A), a light incident surface (11B), and a reflective surface (llc). As shown in FIG. i, the reflector 〇3) is used to reflect the light at the bottom of the light guide plate (11) to re-enter the light guide plate (11). After the light emitted from the light source (12) is incident on the light incident surface (11B), it is transmitted to the left side in the light guide plate (11), and after the reflection of the reflective plate (13) and the reflective surface (He), The illuminating surface (UA) is shot. However, the light guide plate (11) of the present patent has only a single light incident surface, and the light source 〇2) is attenuated after transmitting a certain distance in the light guide plate (11), thereby causing the light guide plate (U) to have a limitation in width. If it is used in a large-size liquid crystal display (not shown), a larger number of light guide plates (11) and light sources (12) need to be disposed, which increases the cost. Here, luminance refers to the luminous flux per unit area. Further, the Republic of China Patent Publication No. 200742914 discloses another edge-lit backlight module. Referring to FIG. 2, FIG. 2 is a schematic diagram of an edge-lit backlight module of the Republic of China Patent Publication No. 200742914. The edge-lit backlight module (2) includes a plurality of light guide plates (21) and a plurality of light sources ( 22), a reflector (23), a diffusion film (25) and a brightness enhancement film (26). As shown in FIG. 2, after the light emitted from the light source (22) is incident on the light incident surface (21B), it is transmitted to the left side in the light guide plate (21), and passes through the reflective plate (23) and the first reflective surface ( 21C), the second reflecting surface (21D), and the second reflecting surface (21E) are reflected by the light emitting surface (2ia). Same as 4 M368093 ground: The light guide plate (8) of this patent only has a single light incident surface (21B), and the light source (5) will attenuate its brightness after transmitting a certain distance in the light guide plate (8), causing the light guide plate (8) to have a width in the gap. Large-size liquid crystal display (trees) requires a larger number of light guide plates (2) and light sources (22), which increases the cost. Therefore, in order to reduce the number of light sources in the edge-lit backlight module and achieve the phase clarity of the light entering the diffused film phase, it is a goal of the general knowledge in the art. [New Content] The purpose of this creation is to provide a highly uniform edge-lit backlight module, so that there is no difference in brightness and darkness on the liquid crystal display, and the number of light sources in the edge-lit backlight module is reduced. . To achieve the above objective, the present invention discloses an edge-lit backlight module including a plurality of light guide plates, a plurality of light sources, a plurality of light guide plates, and a reflection plate. Wherein, the light guide plates are parallel to each other and the lake is on the same plane. The filament is located between two adjacent light guide plates. The reflector is located below the light source and the light guide plate. The light guide plate is a long plate-shaped structure located above the light source, and reflects part of the light emitted from the light source to the light guide plate, and the other part of the light is emitted through the light-emitting surface of the guide. Thereby, the brightness uniformity of all the light emitted from the light guide plate and the light guide plate through the _ light type backlight pattern is 60% to 98%. The luminance uniformity is the ratio of the ratio of the luminance of the darkest point on the side of the backlight format to the luminance of the brightest point. The edge-lit backlight module as described above, wherein the lower side of the left and right sides of the light-guiding plate 5 .M368093 are respectively provided with a through-pull plate, or a plurality of support columns, or a side adjacent to the light-guiding plate on the light guide plate Opening - accommodating the corners, placing the light guide plate over the occlusion angle, and the depth of the occlusion angle is substantially the same as the thickness of the light guide louver. The light incident surface of the light guide plate includes the edge light type backlight module as described above, and has a microstructure. In the edge-lit backlight module as described above, the light-guiding plate is semi-reflective and translucent.
