See Figure 4. The most important case in this case is that the light guide end of the light guide plate 3 near the light emitter 4 is defined as A scattering area 3 1 is a light guide plate 3 with a continuous and spaced acute angle recessed inwardly from the ends of the light guide plate 3 inwardly, so that two adjacent hollow portions 3 2 are light guide plates 3, A continuous and spaced wedge-shaped body 3 3 is formed, and the light source of the luminous body 4 is caused to enter the scattering area 31 when a part of the light source directly enters the light guide plate 3 through the bottom of the wedge-shaped body 3 3, and most of the light sources are The light is refracted through the hollow portion 32 and enters the light guide plate 3; each clock space portion 32 in the scattering area 31 can be refracted by the light source, so that the light source has a scattering effect, and the angle of the light beam of the source luminous body 4 is enlarged, and As a result, more light sources are obtained due to the dark band region 34 between the adjacent luminous bodies 4, and the obvious degree of the dark band region 34 is reduced. In the previous case, the problem to be overcome was indeed achieved. However, in the spirit of excellence, the creators went further and found that some backlight manufacturers have some manufacturers in the assembly process, in which the number and configuration of the light emitters are The position and interval of the light guide plate can be planned and designed in advance. In this way, the design of the light guide plate to overcome the dark zone area can be further changed to better meet its needs. [New content] The main purpose of this creation is to provide a light guide plate structure. The light guide plate is provided with a scattering region at a position corresponding to the luminous body in the light entrance end surface. When the light source of the luminous body wants to enter the light guide plate, By contacting this scattering area, the light source can get many opportunities for refraction in real time, make the light source uniform, and make each luminous body

[Embodiment] The source reduces the position of the dark band area. In order to achieve the work achieved, the hollow surface 5 1 in the corner of 5 1 and the shooting area 5 1 is shown in the light of the luminous body 6. The principle of part of the light is that after the hair is sent, the horse will enlarge the original hair 6 There is more light in each luminous body. Luminous body 6 area 5 2 The table controls the effectiveness of each model. Please refer to the luminous body 1 to form a long source with guide 5 in part 5 1 when the light source will be hollowed out. The light body 6 is obtained on the body 6 due to the beam source, and the dark band of the light of 6 is now on the guide body 5. The inspector can more easily cooperate with the illustration to illustrate the figure 5. The corresponding end of the light 6 in the light creation end 5 1 2 The continuous and spaced light plates 45 and 5 have a better degree of penetration. The light source that is refracted by the luminous body directly through the wedge 5 1 2 is formed by guiding the angle between the angles of the light beams of the multiple refracting light sources. The position of the angle 1 of the light plate 1 entering the light guide plate area 5 2 is directly understood as follows: The light end face of a wedge-shaped body with an outer edge is set so that the light body 5 1 of the scattering 6 enters the light end face, and Degrees, the angle of the light 5 of the light plate 5 2 is also opposite. Please refer to the structure of the original light creation and the light guide plate 5 Scattering area 5 Long continuous area 5 15 13, 5 1 5 1 1 The source enters the bottom light guide plate 5 5 1 The light source is uniform The degree of the original dark band is obvious; the degree becomes larger, becomes larger, read the light incident end 1 1 of the number of light sources shown in Figure 6, the scattered light with a sharp 2 incident light end and the degree of the scattering area, with a slightly greater energy The light emitting part 5 1 1 captures the subsequent light output from the light emitting part, and the light emitting part 5 1 1 is homogenized, and the dark band indication is reduced because the light emitters 5 2 will be obtained at the same time, and thus the two are adjacent.

The scattering region 5 1 1 is formed by protruding outwardly from the outer edge of the light incident end surface 5 1. This work can reduce the dark in the light guide plate 5 without enlarging the distance between the light emitter 6 and the light guide plate 5 or increasing the number of the light emitter plates 6 because of the need to overcome the performance of the dark band area 52 on the light guide plate 5. The obvious degree of the band 5 2 is the performance position, and the arrangement is based on a more economical quantity of the luminescent body 6.
之,有利於應用之商品具有更大的空間予以變化設計,以 達到增進商品之商業價值。 綜上所述’本創作之結構確能增僅使用之功效,且未 見於市面,而具有新穎性及進步性,應已符合新型專利之 要件,爰依法提出申請,祈請貴審查委員之詳鑑,惠賜 為准予專利之審定,至感德便。In other words, the products that are beneficial to the application have more space for design changes, so as to increase the commercial value of the products. In summary, 'The structure of this creation can indeed increase the use-only effect, and it has not been seen in the market, but it is novel and progressive. It should have met the requirements of the new patent. Apply for it according to law. Please ask your review committee for details. In view of this, Huici is the only one who has the right to examine the grant of patents.
