The structure of the light guide plate of the middle side light-emitting device is improved. [Prior Art] Press, generally used in the liquid crystal display of the information device, can choose to use the direct-lit or edge-lit backlight module architecture according to the requirements of # actual design; as shown in the first figure, it is general The structure of the edge-lit backlight module is mainly composed of a point light source 1 〇, a light guide plate 2 〇, a diffusion plate 3 〇 and a 稜鏡 combination 40, and the light guide plate 2 includes a light-incident surface 2 1 , a and the inlet The bottom surface 2 2 intersecting the smooth surface 2 1 and a light exit surface 2 3 opposite to the bottom surface 2 2 , the point light source 1 设置 is disposed on one side corresponding to the light incident surface 2, and receives the point light source 丄〇 The emitted light, the bottom surface 2 2 reflects and scatters the introduced light to form a scattered light line uniformly dispersed in each direction, and the light-emitting surface 2 3 leads the uniformly dispersed light to the light guide plate 2 〇 to guide the liquid crystal display panel In order to achieve the effect of the liquid crystal display panel display. The reflection and scattering of the light from the bottom surface 2 2 are emitted through the halftone dots. Please refer to the second figure. The bottom surface of the light guide plate 20 has a plurality of evenly arranged dots 22! The introduced light is reflected and scattered. f隹, because the light emitted by the point source enters the light-emitting surface 2 into the light-emitting surface 2, so that the light-guide plate 20 is close to the point light source, the light is brighter, and the light from the point source 10 is brighter. Dark, so the dot 2 2 1 design cannot effectively provide uniform brightness. M294666 [New content] There is a 4α here, the creation of the present invention is to provide a light guide plate structure that makes the light passing through uniform, and improves the brightness of the emitted light (4), and increases the taste of the light. - the solution to the "light guide structure improvement" is that the light guide plate _ includes at least a light-incident surface, a bottom surface intersecting the light-incident surface, and a light-emitting surface opposite to the bottom surface, and the point light source The system is disposed on a side corresponding to the light φ surface, wherein any one or both of the light emitting surface or the bottom surface has a plurality of dimming structures, and a plurality of dimming structures are provided with sub-network dots, so that the light of the point light source is adjusted. The light structure and the reflection and scattering of the secondary dots enhance the uniformity of the emitted light and the taste of the light. [Embodiment] and as a whole, so that your reviewers can understand the operation mode of the structure of the creation. The following is a description of the following: Group anti-structural improvement" is mainly for the edge-lit backlight phase. The structure is also improved as shown in the first figure. The end of the plate is the entrance surface 2 b = the bottom surface 22, and the front part is the light exit surface 2 疒 = (4) should be the human face 21 - side, its point source 1 〇 = = body, so that light can be injected from the light-incident surface 21, and then emitted from the front surface of the panel 20 to achieve the light source display effect on either or both sides As shown in the figure, the focus of this case is that the bottom surface or the light-emitting surface is provided with a plurality of dimming structures, please also refer to the surface of the M294666 ^ 2 ° light surface 2 3 ^ £ ^ 3 surface, the groove is formed The dimming structure is configured to work, and each of the dimming structures is arranged in a manner of arrangement. Alternatively, as shown in the fourth figure, the bottom surface 22 of the light guide plate 2 is provided with a plurality of surfaces recessed from the bottom surface 2 2 a dimming structure 5 i formed by an arc, and a plurality of dimming structures around the work 52 provided with the sub-network, each sub-network of the structure 52 as shown in FIG. Fifth, based ^ convex or concave surface of the form 'of which the convex surface of the molding by blasting forlorn available. <, b 2 is the point light source 1 〇 light can be injected from the light entrance surface 2, ^ 2 2 the reflected light is reflected, scattered 'formed evenly in all directions =, the ray 'the bottom surface 22 The dimming structure 51 and the sub-network provided thereon can be distributed to the light-emitting surface 23, or the light-emitting structure 5 provided on the light-emitting surface 23 can be led out to the light guide plate 2 Q, makes the passing level evenly emitted, and improves the uniformity of light brightness, and increases the taste of light. Of course, the form of each dimming structure 5i can be implemented as follows. As shown in the sixth figure, 'each dimming structure 5 tool has two oblique sides 5U, 512 toward the opposite direction, and the first and second oblique sides 5ΐ,: 2 The first and second angles 5 1 3, 5 1 4 are formed at different angles from the bottom surface or the light exit surface, and as shown in the seventh figure, the first and second angles ^ 3, 5 1 4 are the same angle, and The first and second oblique sides 5 work, 5 = can form - curved edges, as shown in the eighth figure; further, each adjustment can also be in the form of a dot, as shown in the ninth figure, and the outlet Straight == two _ point 52 diameter size 'and can be selected for each network as described above, this creation provides a side-light type backlight module, another preferred and feasible M294666 light guide plate structure, 提 提 提 提The implementation instructions and the drawings show the total application for profit-seeking; however, the above limitation of the preferred embodiment of the creation is not similar, similar, and (4) within the structure, installation, features, etc. . It should be the creation purpose of this creation and the scope of patent application.
