New Description: [New Technology Field] This creation relates to the structure of a light guide plate, which aims to provide a uniformity of brightness of the outgoing light, especially for the side light-emitting device used in liquid crystal displays. The structure of the light board is improved. [Prior Art], according to the liquid crystal display of the information device, it is possible to select a direct-lit or edge-lit backlight module structure according to the requirements of the continuous design; as shown in the first figure, The structure of the general edge-lit backlight module is mainly composed of a point light source 1 1 , a light guide plate 1 2 , and a plurality of optical molds 1 3 , and the light guide plate 12 includes a light-incident surface 1 2 1 , a light-incident surface 1 2 1 intersecting bottom surface 1 2 2, a light emitting surface 1 2 3 opposite to the bottom surface 1 2 2, and a surface intersecting the bottom surface 1 2 2 and the light emitting surface 1 2 3 and corresponding to the light incident surface 1 2 1 The side light source 1 1 is disposed on one side of the corresponding light incident surface 1 2 1 and receives the light emitted by the point light source 11 , and the bottom surface 1 2 2 reflects and scatters the introduced light. The scattered light is uniformly dispersed in all directions, and the light-emitting surface 1 2 3 leads the uniformly dispersed light to the light guide plate 12 to be guided to the liquid crystal display panel to achieve the effect of displaying the liquid on the surface of the liquid. The light-emitting surface 123 of the light guide plate 12 is provided with a plurality of V-shaped grooves 14 . When the point light source 11 emits light, the light-emitting surface 1 2 3 of the light guide plate can be illuminated under the refraction of the groove 14 The effect of the gap between the two grooves 1 4 is as shown in the second and third figures M309123', and each groove 14 extends into the surface of the light guide plate 1 to form a depth η. Since the light emitted from the point source 11 enters from the light incident surface 1 2 1 of the light guide plate 12, the portion of the light guide plate 1 2 near the point light source 11 emits light, and the portion away from the point light source 11 is dark. Therefore, the form of the trench 14 may be differently changed, and the distance Ρ or the depth 各 between the trenches 14 is changed in a gradient manner, and the point light source 11 is arranged for the trench 1 having the largest pitch ρ (or depth). In order to make the light emitted from the light surface 1 2 3 relatively uniform. However, each of the grooves 14 extends from the light incident surface 1 2 1 of the light guide plate to the side 10 surface 124, so that the distance or depth between the grooves 14 is between the light incident surface 12 1 and the side surface 1 2 4 . The groove 4 of the corresponding point source 11 has a larger distance Ρ or depth η, and the point source 11 is disposed on the light-input surface 1 2 1, so the light guide 1 2 is away from the point The light received by the light source 1 1 ^ (that is, near the side 1 2 4 ) is the same, but the same light ray is emitted through different pitch Η or depth ,, which will form different luminance performances, making the emitted light luminance uneven. • [New Content] In view of the above, the present invention aims to provide an improvement in the structure of a light guide plate that uniformly emits light passing through and improves the uniformity of luminance of emitted light. The solution for the "structural improvement of the light guide plate" is that the light guide plate comprises at least a light incident surface, a bottom surface intersecting the light incident surface, a light emitting surface opposite to the bottom surface, and a bottom surface and a light emitting surface. Intersecting and corresponding to the side of the light-incident surface, a plurality of grooves are arranged on the light-emitting surface, and the plurality of point light sources are disposed on one side of the corresponding light-incident surface; wherein the two-two grooves M3 09123 have a groove - spacing, and each groove extends into the surface of the light guide plate to form a depth of 'the spacing or depth of the human light surface is not the same pitch and depth arrangement, and the side is the same pitch or depth arrangement, which can improve the uniformity of the emitted light. . [Embodiment] In order to enable the reviewing committee to understand the structure of the creation and the overall operation mode, the following is a description of the following: · The creation of the "Light Guide Plate Structure Improvement" is mainly for the edge-lit backlight module.

In the specific use, the light emitted by the point light source 2 3 enters from the light incident surface 2 1 1 of the light guide plate 2 1 , so that the portion of the light guide plate 2 1 near the point light source 23 is brighter, and away from the point light source 23 The light emission is dark, but the distance between the two light sources 2 2 corresponding to the point light source 23 is greater than the distance P′ and the distance from the point light source 23 is smaller, so that the light is emitted. The light of the surface 2 1 3 is relatively uniform; and the light received by the light guide plate 2 away from the point light source 2 3 (that is, close to the side surface 2 1 4) is the same, and the light is refracted through the equally spaced grooves 2 2 to form the same light. Brightness, which in turn increases the uniformity of the overall emitted light. In the second embodiment, as shown in the sixth embodiment, the two grooves 2 2 also have a pitch P, and the pitches P are arranged in an unequal distance on the light incident surface 21 (such as the seventh figure (A). As shown in the figure, the distance P between the grooves 2 is changed in a gradient manner, and the point source 2 3 is arranged to provide a groove between the two points of the light source 2 3 for the groove 2 2 having the smallest pitch. The distance between the large distances p and the sides 2 1 4 are equally arranged [as shown in the seventh figure (b)], so that the intersection of each groove 2 2 and the light-emitting surface 2 1 3 is curved, which can also improve the overall emission. Light luminance uniformity. In the third embodiment, as shown in the eighth embodiment, each of the grooves 2 2 extends into the surface of the light guide plate 21 to form a depth η, and the depths are arranged at different depths on the light incident surface 21 (such as the ninth figure ( Α)), the depth Η of each groove 2 2 changes in a gradient manner, and the point source 2 3 is for the groove 2 2 5 having the largest depth and the groove 2 2 between the two point sources 2 3 The inter-system has a smaller depth M309123 • degree Η, and is arranged equidistantly on the side 2 1 4 [as shown in the ninth diagram (B)]; of course, as in the fourth embodiment shown in the tenth figure The point source 2 3 is arranged for the trench 2 2 having the smallest depth, and the uniformity of the overall emitted light luminance can also be improved. In the fifth embodiment shown in FIG. 11 , the two grooves 2 2 have a pitch P, and each groove 2 2 extends into the surface of the light guide plate 21 to form a depth Η, each pitch P and The depth is less than the entrance surface 2 1 1 is different pitch and depth arrangement [as shown in the twelfth figure (Α)], the distance between the grooves 2 2 and the depth Η is gradient, and the point source 2 The 3 series is arranged for the groove 2 2 having the smallest pitch and the largest depth, and the groove 2 2 between the two point light sources 23 has a small distance between the turns and the depth Η, and the sides 2 1 4 are the same pitch Ρ And a depth Η arrangement [as shown in the twelfth figure (Β)]; of course, as in the sixth embodiment shown in the thirteenth figure, the point light source 2 - 3 is for the largest pitch and the smallest depth The arrangement of the grooves 2 2 can also improve the uniformity of the overall emitted light luminance.
