INSTRUCTIONS: [Technical Field] The present invention relates to a structure of a light guide plate, and particularly relates to a structure capable of effectively mixing a human light source to facilitate subsequent uniform light emission of the light guide plate. [Prior Art] Pressing 'Liquid Crystal Display (LCD) is mainly composed of a liquid crystal panel (10) Panel) and a backlight module (toe k.). Among them, the liquid crystal panel is used as the display of the face, but the liquid crystal panel itself does not emit light. The money necessary for the display of the 7F is the '疋' provided by the full-side f-light module - the liquid crystal display H Zhongcai is of great importance, and the backlight module must be able to provide a high-luminance and uniform-sounding light source as its primary goal. The high-quality light source is provided as the main responsibility of the light guide plate in the backlight. As shown in FIG. 1, the conventional wedge-shaped light guide plate 1 has a light-emitting surface; the light-emitting surface 11 of the L i L disk is a reflective surface 12 of a relative position, and at least the wire-shaped wire 1 and the reflecting surface 12 are connected to each other - The side surface is the light-incident surface 13; wherein, the light-incident surface is used to receive the light source matched with the light emitted by the external light (4), and the light source is continuously transmitted inside the light guide plate 1 'The light source A can be the second reading (10) Fresh (10)L), the light-emitting surface U is off, the light source is away from the light guide plate body, and the liquid crystal panel is applied. The reflective surface 12 can reflect the light source to be heard, and then travel toward the light surface. By. The reflective surface 12 is densely covered with a strip-shaped light conductor U having a triangular cross section to cause the light source to illuminate the reflective surface! At the same time as the two rows of reflections, the strips of the three-and-fourth strips of the 200949322 light conductor 14 achieve the effect of concentrating the light source, and the direction of travel of the light source after the reflection is reflected, and the other side of the light-emitting surface 1 1 is subjected to sand blasting or the like. The processing method is used to roughen it. When the light source is separated from the light-emitting surface 11, the light-emitting surface is formed by scattering. The light source is scattered to achieve the purpose of homogenizing the light. As shown in FIG. 2, another conventional wedge-shaped light guide plate 2 is designed to form a thick-chained reflection surface 2 2 and a light-emitting surface 21 is provided with a strip-shaped light conductor 2 4 ' After the light surface 23 is incident and transmitted to the light guide plate 2, the light source that is incident on the reflection surface 22 will first scatter the light source, and then travel toward the light exit surface 21, and then leave the light guide plate 2 At the same time, the strip light guide 2 is passed through the light-emitting surface 2, and then the light source is concentrated to guide the traveling direction of the light source. The above two conventional light guide plate designs are all arranged on the reflective surface or the light exit surface of the light guide plate, and one of the two is provided with a strip-shaped photoconductor having a triangular cross section, and the strip light guide is used for correcting and guiding the light source. On the other hand, the reflective surface or the rare surface of the surface is roughened to be used as a light source for diffusion. However, these designs have insufficient light mixing properties for the light source of the light source, and it is still easy to make the output of the overall light source uniform, which is not advantageous for subsequent liquid crystal panels (LQ) (4). SUMMARY OF THE INVENTION The present invention relates to a structure of a guide wire which is made of a light-transmissive material, such as a light-emitting source, a reflection surface, a surface, and an anti-human light surface. The light-emitting surface guides the light source from the light guide body to the outside, and the reflective surface reflects the light source that is incident on the 200949322, changes the direction of the light source and then advances toward the light-emitting surface, and the light-incident surface is configured by the text. The light source from the light source 'transmits the light source inside the wire. The main object of the present invention is that the light source can be improved by the light guide plate of the present invention, and the light source of the conventional guide wire can be improved to achieve uniformity of the output light source, so as to facilitate the subsequent supply of the liquid crystal panel display.

The light surface is disposed in the same direction as the reverse light surface, and each strip-shaped light guide is arranged in a continuous or spaced arrangement, wherein the light-emitting surface or the reflective surface is provided with a light-guiding structure, thereby When the light source is reflected and transmitted by the reflecting surface in the vertical direction, and when the light-emitting surface is refracted by the light-emitting surface, the strip can be shot by the strip-shaped material of the thin and reflective surface towel, and at the same time, by setting it on the output ^ ^ The guiding light of the surface framing can make the light source more and more 乂 ' 使 之 之 人 人 人 人 丝 丝 丝 丝 获得 获得 获得 获得 获得 获得 获得 获得 人 获得 获得 人 人 人 人 人 人 人 人 人 人 人 人 人 人 人 人 人[Embodiment] and the proposal-step-by-step method of the case, and the sister of the production, 'Lang Ruhou'; The present invention is related to the kind, the light guide plate of the present invention has a light-emitting: Referring to FIG. 3, the reflecting surface 3 2 is connected to the light emitting surface 31 and is connected to the light emitting surface 3 200949322, the light incident surface 3 3 , and the light incident surface 3 3 . The reverse direction of the position is 3 4 . Wherein, the light-emitting surface 3 1 and the reflective surface 32 of the light guide plate 3 are provided with a plurality of strip-shaped light conductors 3 5 ' 荨 荨 荨 strip-shaped light conductors 3 5 are connected continuously and from the light guide plate. The surface 3 3 is disposed in the same direction as the reverse entrance surface 34, wherein the pure surface of the strip-shaped photoconductor 35 is curved to facilitate the light mixing effect of the light source. Even, as shown in Fig. 4, the cross-section of the strip-shaped photoconductors 35 can be curved, and the diffusion effect on the light source can be made larger. ® Continued as shown in the next section, 'When the light source A of the light source A self-guides the green light into the light surface 3 3 into it, the light source will be transmitted inside the light guide plate 3, and the light source that falls on the reflective surface 32 It will reflect again. If the light source passes through the light exit surface 3丄, if it is smaller than the critical angle, the light source will be refracted from the light exit surface 31, and the light will fall on the reflective surface 32, and the reflective surface will be densely covered by the reflective surface. The photo-conductor 35 has an arc-shaped cross section of the top surface of the strip-shaped photoconductor 35, so that the light source shape 0 can be scattered, and the light source when the reflective surface 32 is reflected has The effect of the scattering diffusion; in addition, when the light source passes through the light-emitting surface 31 to leave the light guide plate 3, the light-emitting surface 31 also has a strip-shaped light conductor 35, and the filament is refracted through the strip-shaped light conductors 35.

Referring to FIG. 7 again, when at least one of the light-emitting surface 31 or the reflective surface 32 of the light guide plate 3 of the present invention is closer to the light-incident surface 33, the closer to each of the strip-shaped photoconductors 35 The smaller the height of the strip-shaped photoconductor 35 is, and the closer the position of the strip-shaped photoconductor 3 5 is, the smaller the height of the strip-shaped photoconductor 35 is, so that it is closer to the position of the incident surface 3 3 . The light source is close to the light source and has a large light intensity, and the light source leaked from the reverse light surface 34 is subjected to the back frame of the light guide plate 3 (not shown) in response to the position close to the reverse light surface 34. The reflection causes the light source to enter the light guide plate 3 again from the reverse incident surface 34, and a large intensity of light is also formed there. Referring to FIG. 8 again, at least one of the light-emitting surface 3丄 or the reflective surface 32 of the light guide plate 3 of the present invention can be further densely covered to guide or guide the light guiding structure 36'_ densely guided on the surface.
