Description of the Invention: [Technical Field] The present invention relates to a backlight module, in particular, a plurality of concentrating elements are disposed on a light-emitting surface of a light guide plate, and a micro-light conductor is disposed on the optical cymbal Model, group structure. [Prior Art] According to a thin film transistor liquid crystal display (the light source of TFT-L (8) is provided by a backlight module (BadUight M_e), the f-light module must be provided with the light source _« Degree, Fangzusaki throws good follow-up application effect. Eight middle 'shown in Figure 1' -f optical module 1 contains at least 彳··-light guide plate 1 1 , reflective diaphragm 12, a number of optical filmmakers 3, and the lamp 4; the light guide plate 11 has at least a personal smooth surface 丄, and a _reflecting surface U and a light emitting surface 1 i 3, the human light surface iii is still accommodating to accept the source of the light source 'And make the light source to the inside of the light guide plate i. And in the reverse only a very large number of light guide points 1121, paste the light guide point 1 more interesting touch, make the red money _ the result of the reaction, Mosquito surface 1 1 3 _ to make the light source in the light guide plate ii the outer wheel ^, a reflection then 12 is placed outside the reflective surface 112 of the guide 11 / can be called the singer! Transfer. In the middle of the light, the upper surface of the light surface 1 is not limited to the optical, then the 1 3 is set on the light guide plate] 2 200819855 3, the optical film 13 has the light The diffusion film (Diffusion fiim) of the diffusion effect is used, and the prism film 1 3 2 which can make the light source perform the concentrating effect, and depending on the actual situation, respectively, The mutual shouting order changes to the g-feeding, and the towel, the 稜鏡 稜鏡 3 3 3 is formed on one of the surfaces and has a plurality of finely shaped cylinders 丄 3 2 丄, and the 稜鏡 体 1 1 2 1 and straightly lined up on the surface of the film cutter 3 2, and in the cylinder of the diaphragm 2 1 2; [3 2丄 is arranged perpendicular to each other to achieve the right The concentrating efficiency of the light source in all directions; the light source 14 is the main surface of the light society, and is mainly disposed outside the light-emitting surface of the light-guide plate ,], which makes the distribution of the product specifications differently. 0 The backlight module 1 in the above is required to be provided with two prism film cutters 3 2, which is enough to complete the concentrating effect on the light. However, the tilt of the i 3 2 is very expensive, often causing the back group One of the main reasons for the high cost of 1 is that 'as shown in Figure 2' has recently developed another-backlight mode, group 2, the back; module 2 contains at least: The light guide plate 2 1 , the reverse _ 2 2 , the her film 2 3 , the protective film 2 4 and the light source 2 5 ; the light guide plate 21 has at least one light incident surface 211 and a reflective surface 212 like the light surface 2 1 3 'Where' the human wire 2 1 1 is used to receive the light source of the light source 25 rounds, the reflecting surface 212 can reflect the light source incident thereon, and the light emitting surface 13 is to output the light source inside the light guiding plate 21 to the outside. The light-emitting surface is used in 200819855 3 and is formed with a pole-shaped cylinder 2 i 3 : so that the light source is used by the cylinder 2131 when it leaves the light guide plate 21, and To achieve the action of collecting light, the light source of the secret axis light guide plate 2, and then concentrating in the other direction by the cylindrical body 2 3 1 on the diaphragm 2 3, so that the silk can be concentrated in a specific direction. efficacy. Since the diaphragm 21 in the backlight module 2 only needs to use one sheet, the effective concentrating performance of the light source can be achieved, and the field can be effectively reduced, so that it is gradually used by those who are in difficulty. However, as shown in FIG. 3, although the light source outputted by the backlight module 2 has been converted from a linear light source to a planar light source, the overall light source is the 稜鏡 diaphragm 2 2 on the 稜鏡 diaphragm 2 31 The function is to form a regular linear beam traveling; the thin film transistor (TFT) 3 1 and the color filter (CF) 3 2 in the liquid crystal panel 3 are very fine phases. The corresponding matrix configuration is formed, so it is a linear beam with a regularity. Once the gap between the cells in the thin film transistor 31 and the color filter 32 is passed, the passing beam is generated. Diffraction is formed, and interference fringes 3 3 are formed on the liquid crystal panel 3. Finally, the performance when the liquid crystal panel 3 is displayed is destroyed. For the formation phenomenon of the above interference fringes 3 3, when the backlight module factory is set up as the optical module, it is impossible to know whether or not there will be a situation, and it is required to be delivered to the LCD panel factory after being assembled. When you start the display of the LCD panel, you will know it. Therefore, it often causes the backlight module factory and the LCD panel factory to cooperate with the 200819855, which is extremely difficult to overcome. SUMMARY OF THE INVENTION The main object of the present invention is to overcome the phenomenon that the light source after the action of the conventional backlight module is too regular, so that the county enjoys the self-turning and gives the liquid crystal panel when the liquid crystal panel is displayed. Interference bars and lines are not conducive to the performance of the overall brightness of the LCD panel. To this end, the technical means used in the present invention provides a backlight module including at least: a light guide plate, a reflective film, an optical film, and a light source, the light guide plate having at least a personal wire, a reflective surface and a filament, the illuminating surface or the reflecting surface is provided with a plurality of concentrating elements, and each of the concentrating trees has a triangular cross section, and the optical (four) of which is provided with a strip of the shirt The micro-light guide body has two or more families per micro-light body, and the peak system of the micro-light guide body is high or low, and the peak or scale is allowed to be respectively The design of continuous undulation under the rhythm or high red, so that the light forest that is read by the light guide plate is too much - the rule that the silk of the mosquito is not completely linear after passing through the optical film. Shape, and the system includes a continuous curved shape, and the light beam is output, so that the thief transistor and the color filter of the liquid crystal panel towel can make the liquid crystal panel display without interference fringes and improve the overall light source. The brightness of the output.
