[Previous technology] Because the backlight module is mainly used for liquid crystal display surfaces that do not have light emitting characteristics to provide sufficient brightness and distribution For a uniform surface, refer to the first figure. One of the conventional light source (1 1), light guide plate (1 2) (1 4), and light guide plate (1 5) can be set on the light guide plate (1 2). Light plate (12); The light guide guides the light in the transmission direction so that the light is emitted uniformly by the light guide 21). The reflection sheet (the bottom surface (122) of (12) is set to 2) and the bottom surface (122) is formed and emitted from (1 · 2 3) The light rays once again increase the utilization rate of the light; the diffuser sheet is relatively out of the light guide plate (1 2), so that the exit surface from the light guide plate (1 2) is more uniform, and the surface of the liquid crystal display is more suitable for the light source (1 1). There is a light from a light source (1 1). In particular, it refers to a liquid crystal display (LCD), so that a panel can reach the display effect, and light to the panel. The backlight core group (10) is mainly composed of light, a reflection sheet (1 3), and a diffusion sheet. Wherein, the light source (1 1) side or two opposite sides, and the function of the light emitting plate (1 2) is that the exit surface (1 1 3) of the light guide plate (12) is disposed relative to the light guide plate to separate the light from the light guide plate. The microstructure of the light guide plate (1 bottom surface (1 2 2) is projected into the light guide plate (1 2), (14) and the fascia plate (15) and the light emission surface (1 2 1) are sequentially arranged, (1 2 1) The brightness and uniformity of the outgoing light distribution plate, and the lampshade (16) for effective use

Creation instructions (2) However, since the light guide plate and the recessed microstructure (1 2 3) formed on the bottom surface (丄 2 2 Z) are circular grooves, the light source, and the microstructure (1 2 3) '1 1) showing the second refraction and increasing energy, the light guide effect will be worsened, and the brightness will be reduced, so that the light guide plate (: [2) is ideal, Practicality and progress today ^ evenness cannot be improved. Therefore, at goal 7, sincerely strive for improvement [new content] (this creation), by changing the brightness of the board and the reason, depending on the base shape of the light guide plate, thereby using the highlight The rate is related to the other effects of this invention, as later. The guide 2 μ is to provide a light guide plate microstructure (two uniformity. Microstructure structure, which can increase the light guide === supply-a kind of light guide plate microjunction • (two), to reduce the light Ϊ if ·, And each microstructure is conical and concave: ίί refraction, reducing energy loss, and it is used to achieve the brightness and uniformity of the first # 日 ^ 出 出. Here is a list of the techniques, handwork, and goodness used: Λ Example and detailed description with the drawings [Implementation] The figure shows the second of this creation. The light guide plate (Example 0) is firstly please refer to the second and one provided by Muzhong 4 but wait for the first board. Microstructure circle Page 9 M264503 V. Creation instructions (3) The transparent material is used to illuminate the number of microstructures () and the bottom surface (2 triangular cone concave 1) of the bottom surface of light and line. According to this, more light-consuming phases are 'improved in uniformity. Used for receiving), and (22) a complex plate (20 shape) is formed into an angular shape (3 1 1), so that the energy brightness can be reduced. And a kind of guide cloth) is presented by three 2) The light guide plate is made of a triangular cone shape and has an incident surface (2 1) and an incident surface (22), which are connected to the incident surface (21), and the light guide plate (2 0) is derived from the one and the exit surface (23). 'While distributing 3 0) on the bottom surface (23), it is worth noting that the microstructure (30) arranged in the light guide 3) is a triangular microconcave microstructure (30) consisting of three identical three Grooves' and internal angles (3 regular triangles) of the triangle (31). Refraction occurs through the microstructure (30) line that is triangular and concave in the shape of a triangle, reducing the secondary refraction of light and reducing the utilization of light, so that the light guide plate can be compared.

Creation instructions (4) For the best brightness and uniformity, please refer to Figures 6 and 7 for a light guide plate microstructure (2 /, provided by the third embodiment of this creation:-Its and The first embodiment is different in that the light guide plate (20, produced) has a triangular pyramid shape. The microstructure (30) of one surface (23) is a concave two cone shape composed of three triangles. The microstructure (3 0) is a triangle (3 4). $ ㈤, said 摅: the middle two triangles (3 3) and the other microstructure (3 0) can be etched privately. The second refraction of the line reduces the energy. Second, more light is refracted, which reduces the light plate to obtain a better light intensity and uniformity. The light utilization rate of the south light is reduced. For the light guide, please refer to the eighth and ninth photos +. Structure (2) ', which is different from that provided by J: The first and second examples are that the bottom surface (2) of the light guide plate (20) is conical and concave, and the notch (3 5) is乂 吉基 （30 〇 through the microstructure (30) conical and concave shape and Er Feng, shape, according to this, produce refraction, reduce Second refraction of the line reduces: = the utilization ratio of more light to make the light guide plate get better light; 2 = = to increase the uniformity of the light ^ sentence. Please refer to the one shown in Figures 10 and 11 Microstructure of the light guide plate (2), which is different from the first embodiment
