[0002] 一般而言，顯示面板大多需要外加一光源模組，用以提 供亮度充足且分佈均勻的光源，藉此達到均勻、高亮度 、廣視角的顯示效果；又依光源模組的設置位置來說， 安裝在玻璃顯示器前的光源模組稱之為前光模組（Front Light Module)。 [0003] 前光模組係透過導光結構來將點或線光源轉化亮度均勻 的面光源產品。在白天或環境照明充足的狀況下，前光 模組可利用外在光源來提供均勻的亮度；另一方面，當 外在光源不足時，前光模組可即時啟動光源，以令面板 能夠正常顯示影像。因此，採用前光模組的顯示面板可 大幅提高省電性能，適合應用在個人數位助理、智慧型 行動電話、及電子書閱讀器等可攜式資訊設備上。 [0004] 然而，傳統前光模組在使用上經常有眩光的現象發生， 或有亮度不足或不均的情形；此外，由於前光模組的導 光板上可能成型有多數的微結構，以藉由該微結構來將 光源分佈成均勻輝度的面光源；惟在使用時，使用者卻 仍可隱約見到微結構刻痕的存在，降低使用時的舒適度 ，此為本創作人所欲積極改良之處。 [0005] 有鑑於此，本創作人為達到上述目的，乃特潛心研究並 10121337(P編號 A〇101 第3頁/共12頁 1012042974-0 M441846 配合學理之運用，终於提出一種設計合理且有效改善上 述缺失之本創作。 【新型内容】 [0006] 本創作之一目的，在於提供一種前光模組，據以避免使 用面板時產生眩光，並增加亮度及均勻度。 [0007] 為了達成上述之目的，本創作係為一種前光模組，以組 設在面板之前方，面板具有可視區，前光模組包括光源 、導光板及中介層，導光板設置在面板的外側，導光板 接收光源所發出的光，並予以反射及折射至面板上，導 光板於平行面板的至少一側邊具有複數微結構，中介層 填佈在微結構内。 [0008] 本創作之另一目的，在於提供一種前光模組，其導光板 於平行中介層之側邊設有複數微結構，藉由本創作之前 光模組的設置，可避免隱約見到微結構刻痕的情況發生 ，增加使用上的舒適度。 [0009] 相較於習知，本創作之前光模組係將中介層填佈在導光 板的微結構内，由於令介層是由水、膠體或矽膠等物質 所構成，當光線通過中介層時可具有更佳的折射及導光 效果，據此將光線均勻且全面性地反射及折射至面板， 以提供面板足夠的亮度，藉此增加光均勻度及亮度，增 加本創作之實用性。 【實施方式】 [0010] 有關本創作之詳細說明及技術内容，配合圖式說明如下 ，然而所附圖式僅提供參考與說明用，並非用來對本創 1〇121337(Ρ编號删1 第4頁/共12頁 1012042974-0 Μ44Γ846 作加以限制者。 [0011] 請參照第一圖，係為本創作之前光模組的組合剖視圖； 本創作之前光模組1係用以組設在一面板2之前方，該面 板2係具有一可視區3。該前光模組1包括一光源10、一導 光板20、及一中介層30，其中，該光源10係位在該導光 板20及該中介層30的側邊。[0002] In general, most of the display panels need to be provided with a light source module for providing a light source with sufficient brightness and uniform distribution, thereby achieving a uniform, high-brightness, wide viewing angle display effect, and depending on the position of the light source module. In other words, the light source module installed in front of the glass display is called a Front Light Module. [0003] The front light module transmits a point or line light source into a surface light source product having uniform brightness through a light guiding structure. In the daytime or when the ambient lighting is sufficient, the front light module can use the external light source to provide uniform brightness; on the other hand, when the external light source is insufficient, the front light module can instantly activate the light source to make the panel normal. Display images. Therefore, the display panel using the front light module can greatly improve the power saving performance, and is suitable for portable information devices such as personal digital assistants, smart mobile phones, and e-book readers. [0004] However, the conventional front light module often has glare in use, or there is insufficient or uneven brightness; in addition, since the light guide plate of the front light module may be formed with a large number of microstructures, The micro-structure is used to distribute the light source into a uniform luminance surface light source; however, when used, the user can still see the existence of the micro-structured nicks and reduce the comfort during use, which is what the creator desires. Positive improvement. [0005] In view of this, in order to achieve the above objectives, the author has devoted himself to research and 10121337 (P No. A〇101, page 3/12 pages, 1012042974-0, M441846, with the use of theory, finally proposed a reasonable and effective design. To improve the above-mentioned creations. [New content] [0006] One of the purposes of this creation is to provide a front light module that avoids glare when using a panel and increases brightness and uniformity. [0007] The purpose is that the front light module is set in front of the panel, and the panel has a visible area. The front light module includes a light source, a light guide plate and an interposer. The light guide plate is disposed outside the panel, and the light guide plate is received. The light emitted by the light source is reflected and refracted onto the panel. The light guide plate has a plurality of microstructures on at least one side of the parallel panel, and the interposer is filled in the microstructure. [0008] Another object of the present invention is A front light module is provided, wherein the light guide plate is provided with a plurality of micro structures on the side of the parallel interposer layer, and the micro-structure can be avoided by the setting of the optical module before the creation. The occurrence of traces increases the comfort of use. [0009] Compared with the prior art, the optical module prior to the creation of the optical module is to fill the interposer in the microstructure of the light guide plate, because the interlayer is made of water and colloid. Or a substance such as silicone, which can have better refraction and light guiding effect when the light passes through the interposer, thereby uniformly and comprehensively reflecting and refracting the light to the panel to provide sufficient brightness of the panel to increase the light. Uniformity and brightness increase the practicality of the creation.
