Description
本發明係針對背光模組當中的光學膜片製造方法及其製造裝置，旨在提供一可製造無基材光學膜片之方法及裝置。The present invention is directed to an optical film manufacturing method and a manufacturing apparatus therefor in a backlight module, and aims to provide a method and apparatus for manufacturing a substrateless optical film.
按，一般應用在資訊裝置的液晶顯示器，係可以依照實際設計之需求，而選擇利用直下式或者是側光式的背光模組架構；如第一圖所示，即為一般側光式背光模組之結構，主要由點光源11、導光板12以及複數光學膜片，各光學膜片可以為擴散板13及稜鏡片14而組成，該點光源11則係設置於對應該導光板12之側邊，接收點光源11發出之光線並導向上方之各光學膜片，最後朝向液晶顯示面板15射出，以達到液晶顯示面板顯示之效果。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 actual design requirements; as shown in the first figure, it is a general edge-lit backlight module. The structure of the group is mainly composed of a point light source 11, a light guide plate 12 and a plurality of optical films, and each of the optical films may be composed of a diffusion plate 13 and a cymbal plate 14, and the point light source 11 is disposed on the side corresponding to the light guide plate 12. The light emitted from the point source 11 is received and guided to the upper optical film, and finally emitted toward the liquid crystal display panel 15 to achieve the effect of the liquid crystal display panel display.
其中，該擴散板13之作用係將光線均勻擴散而達到均光之效果，而該稜鏡片14係用以增加亮度；而一般擴散板或稜鏡片等光學膜片之結構，多係具有一基材層A，如第二圖(A)、(B)所示，該基材層A上並設有擴散層B，以形成擴散板13，或該基材層A上設有增光層C，以形成稜鏡片14；而該擴散板或稜鏡片之製造方法及裝置可如第三圖所示，該圖係以製造稜鏡片為例，係先由輸送輪提供基材層A，再於該基材層A上佈滿光固化樹脂D，再將佈滿有光固化樹脂D之基材層A輸送至一圖案化之成型輪E進行加壓成型，該成型輪E上係設有複數成型結構E1，使該光固 化樹脂D表面形成與該成型結構E1相對應之溝槽C2，再經由UV燈F照射，使該光固化樹脂D固化成型於基材層A上而形成稜鏡片14結構。Wherein, the function of the diffusing plate 13 is to uniformly diffuse the light to achieve the effect of homogenizing, and the cymbal 14 is used to increase the brightness; and the structure of the optical film such as the diffusing plate or the cymbal has a basic structure. The material layer A, as shown in the second figures (A) and (B), is provided with a diffusion layer B on the substrate layer A to form the diffusion plate 13, or the substrate layer A is provided with a brightness enhancement layer C, To form the cymbal sheet 14; and the method and apparatus for manufacturing the diffusion sheet or the cymbal sheet can be as shown in the third figure, which is an example of manufacturing a cymbal sheet, which is first provided by the conveying wheel, and then The substrate layer A is covered with a photocurable resin D, and the substrate layer A covered with the photocurable resin D is transported to a patterned forming wheel E for pressure molding, and the forming wheel E is provided with a plurality of moldings. Structure E1, making the light solid The groove C2 corresponding to the molding structure E1 is formed on the surface of the resin D, and is irradiated with the UV lamp F to cure the photocurable resin D on the base material layer A to form the cymbal 14 structure.
惟，上述擴散板或稜鏡片等光學膜片之結構中，均設有一基材層用以承載擴散層、增光層或其他光學結構層，該基材層之設置不僅增加整體光學膜片之厚度，且該基材層之材質大多為聚對苯二甲酸乙二醇酯(PET)或聚乙烯(PE)等材質，而該擴散層或增光層大多為UV膠材質，兩者不同之材質間對於光線之折射率亦不相同，故光線由空氣進入基材層時，會有部分光線被折射，再經由擴散層或增光層時，亦會有部分光線被折射，使得光線經由光學膜片後會有較高之光線損耗，進而使得整體光線利用率降低。However, in the structure of the optical film such as the diffusion plate or the cymbal sheet, a substrate layer is disposed to carry the diffusion layer, the brightness enhancement layer or other optical structure layer, and the substrate layer is disposed not only to increase the thickness of the integral optical film. The material of the substrate layer is mostly made of polyethylene terephthalate (PET) or polyethylene (PE), and the diffusion layer or the brightness enhancement layer is mostly made of UV glue, and the materials are different between the two. The refractive index of the light is also different. Therefore, when the light enters the substrate layer by air, part of the light is refracted. When passing through the diffusion layer or the brightness enhancement layer, some light is also refracted, so that the light passes through the optical film. There is a higher light loss, which in turn reduces overall light utilization.
有鑑於此，本發明即在提供一種可製造無基材光學膜片之方法及裝置。In view of the above, the present invention provides a method and apparatus for producing a substrateless optical film.
本發明之製造方法主要係於光學膜片製造過程中提供一暫時性輔助載體，以供承載成型材料，使該成型材料表面進行預成型及固化成型後，再將該輔助載體脫離該成型材料，以完成無基材之光學膜片結構。The manufacturing method of the present invention mainly provides a temporary auxiliary carrier in the optical film manufacturing process for carrying the molding material, and after the surface of the molding material is preformed and solidified, the auxiliary carrier is removed from the molding material. To complete the substrate-free optical film structure.
其中該光學膜片係不具有基材，故整體厚度降低，且該光學膜片僅具有單一折射率之本體，使得光線僅經由一次之折射，以降低光線損耗進而提高光線利用率。Wherein the optical film does not have a substrate, so the overall thickness is reduced, and the optical film has only a single refractive index body, so that the light is refracted only once, so as to reduce light loss and thereby improve light utilization.
