1282887 五、發明說明（5) 設置於靠近入光側1 3之區域及出光側1 4區域，以同時 避免此二區域之成像現象。 請參閱圖六所示，本發明係提供一種背光模組，其主 要係於導光板1之一面（出光面1 1或底面1 2皆可，本 實施例為製造V型溝槽於底面1 2 )，另一面1 1則可為 鏡面或微結構面，再該導光板1 一端為入光側1 3，該入 光侧1 3 —端配置有光源2，供光源2發出之光線2 1自 入光侧1 3進入，透過導光板1之V型溝槽1 2 1及 1 2 2反射光線2 1 ，使其從出光面1 1出光，致使導光 板1表面產生亮度； 其中，該反射面（底面）1 2前端區域（從端面到約 靠近光源2 0公釐處之區域），分佈多數凹形狀或凸形狀 之V型溝槽1 2 1 ，此一區域之V型溝槽1 2 1的角度乃 呈不規則且無規律的變化，以避免因角度相同或連續變化 而造成燈源成像，使背光模組外觀不良； 該不規則區域V型溝槽1 2 1角度呈不規則變化，但 其深度或間距變化則依照均勻性之要求並依角度變化之設 計，經光學設計而得：可為固定間距，變化深度（如圖七 );亦可為固定深度，變化間距（如圖八）；或是間距、 深度二者皆變化（如圖七）。 在不規則區之後則接續規則區域，其上之V型溝槽1 2 2則角度相同，或是逐漸連續的變化，但其間距則可由 疏而密連續變化之分佈；其深度也可由淺至深連續變化， 以達到均勻性之要求。1282887 V. INSTRUCTION DESCRIPTION (5) The image is placed near the light-incident side 13 and the light-emitting side 14 to avoid the imaging phenomenon of the two regions. Referring to FIG. 6 , the present invention provides a backlight module, which is mainly used on one surface of the light guide plate 1 (the light exit surface 11 or the bottom surface 1 2 can be used. In this embodiment, a V-shaped groove is formed on the bottom surface 1 2 . The other side 1 1 may be a mirror surface or a microstructured surface, and the light guide plate 1 has a light incident side 1 3 at one end, and a light source 2 is disposed at the light incident side 1 3 end, and the light source 2 1 is supplied from the light source 2 The light-incident side 1 3 enters, and the V-shaped grooves 1 2 1 and 1 2 2 of the light guide plate 1 reflect the light 2 1 to emit light from the light-emitting surface 1 1 , so that the surface of the light guide plate 1 generates brightness; wherein the reflective surface (bottom surface) 1 2 front end region (from the end surface to a region approximately 20 mm apart from the light source), a V-shaped groove 1 2 1 having a plurality of concave or convex shapes, and a V-shaped groove 1 2 1 of this region The angle is irregular and irregular, to avoid imaging of the light source due to the same or continuous change of the angle, so that the appearance of the backlight module is poor; the irregularity of the V-shaped groove 1 2 1 is irregular. However, the depth or pitch variation is designed according to the requirements of uniformity and angle change. It may be a fixed distance, variation in the depth (FIG. VII); may also be a fixed depth, the pitch variation (FIG. VIII); or pitch, depth Both of these changes (FIG. VII). After the irregular zone, the regular zone is continued, and the V-shaped groove 1 2 2 has the same angle or a gradual continuous change, but the pitch can be continuously and uniformly changed; the depth can also be as shallow as Deep continuous changes to achieve uniformity requirements.
1282887 五、發明說明（6) 為使本發明更加顯現出其進步性與實用性，茲與習用 作一比較分析如下： 本發明優點 1、 可消除背光模組前端（靠近入光侧）或後端（靠 近出光侧）區域成像產生。 2、 使背光模組發揮至最佳之色彩及亮度。 3、 亮度均勻一致。 綜上所述，本發明在突破先前之技術結構下，確實已 達到所欲增進之功效，且也非熟悉該項技藝者所易於思 及，再者，本發明申請前未曾公開，其所具之進步性、實 用性，顯已符合發明專利之申請要件，爰依法提出發明申 請01282887 V. INSTRUCTIONS (6) In order to make the present invention more progressive and practical, a comparative analysis is used as follows: Advantages of the invention 1. The front end of the backlight module (near the light entrance side) or the rear can be eliminated. The end (near the light exit side) area is imaged. 2. Make the backlight module to the best color and brightness. 3, the brightness is uniform. In summary, the present invention has achieved the desired effect under the prior art structure, and is not familiar to those skilled in the art. Further, the present invention has not been disclosed before the application, and it has Progressive and practical, it has already met the application requirements of the invention patent, and submitted an invention application according to law.
