Description
本發明是有關於一種保護膜，且特別是有關於一種用於顯示器之偏光板保護膜。The present invention relates to a protective film, and more particularly to a polarizing plate protective film for a display.
近年來，液晶顯示器已成為平面顯示器的主流。在液晶顯示器的製造過程中，包括有薄膜電晶體陣列基板的製造、彩色濾光片的製造、填充液晶材料、以及在模組廠組裝成為液晶顯示器模組。In recent years, liquid crystal displays have become the mainstream of flat panel displays. In the manufacturing process of the liquid crystal display, the manufacture of the thin film transistor array substrate, the manufacture of the color filter, the filling of the liquid crystal material, and the assembly into a liquid crystal display module at the module factory are included.
在薄膜電晶體陣列基板與彩色濾光片之間填充液晶材料，並且完成封合後，即完成液晶面板的製作。因為填充液晶材料的過程必須在無塵室中進行，而完成液晶面板封合後的後續組裝作業並不須在無塵室中。因此，封裝液晶面板與模組廠通常是在不同廠區。當製作完成液晶面板後，便將液晶面板運送到模組廠組裝，用以將液晶面板、電路板以及背光模組構裝成為一個完整的液晶顯示器模組。The liquid crystal material is filled between the thin film transistor array substrate and the color filter, and after the sealing is completed, the fabrication of the liquid crystal panel is completed. Since the process of filling the liquid crystal material must be performed in the clean room, the subsequent assembly work after the liquid crystal panel is sealed does not have to be in the clean room. Therefore, the packaged LCD panel and module factory are usually in different factories. After the LCD panel is completed, the liquid crystal panel is transported to the module factory for assembly, and the liquid crystal panel, the circuit board, and the backlight module are assembled into a complete liquid crystal display module.
在液晶面板運送到模組廠過程中，液晶面板是彼此堆疊在一個容置箱中。為了避免液晶面板之間彼此緊密黏附在一起，在每一片液晶面板之間設置有間隔墊。但是此種方式浪費了許多空間，並造成運送體積龐大。而且，在模組廠將液晶面板區取出時，自動化提取裝置必須將設置於液晶面板之間的間隔墊取出，導致作業時間不必要的延長。During the transportation of the liquid crystal panel to the module factory, the liquid crystal panels are stacked on each other in a housing box. In order to prevent the liquid crystal panels from sticking to each other closely, a spacer pad is disposed between each of the liquid crystal panels. However, this method wastes a lot of space and causes a large shipping volume. Moreover, when the module factory takes out the liquid crystal panel area, the automatic extraction device must take out the spacers disposed between the liquid crystal panels, resulting in an unnecessary extension of the working time.
因此，本發明之一目的係提供一種偏光板保護膜，其能達成在相互堆疊之液晶面板之間，不需使用間隔墊。Accordingly, it is an object of the present invention to provide a polarizing plate protective film which can be realized between liquid crystal panels stacked on each other without using a spacer.
本發明之另一目的係提供一種偏光板保護膜，俾能防止相互堆疊之液晶面板間彼此吸附。Another object of the present invention is to provide a polarizing plate protective film which can prevent liquid crystal panels stacked on each other from adsorbing each other.
為達上述目的，本發明之偏光板保護膜包括有一下表面，用以附著於一液晶面板之一偏光板上；以及一上表面，該上表面具有紋路以及由該紋路所圍繞成之長寬不小於2公分之平坦區域，其中該紋路防止貼附有該偏光片保護膜之液晶面板間彼此吸附，而該平坦區域供一真空吸嘴吸附提取該液晶面板。To achieve the above object, the polarizing plate protective film of the present invention comprises a lower surface for attaching to a polarizing plate of a liquid crystal panel; and an upper surface having a grain and a length and width surrounded by the grain A flat region of not less than 2 cm, wherein the texture prevents adsorption between the liquid crystal panels to which the polarizer protective film is attached, and the flat region is for a vacuum suction nozzle to adsorb and extract the liquid crystal panel.
上述本發明之偏光板保護膜，其中該紋路可為縱橫垂直交錯的凹槽，或是為斜紋走向交錯的凹槽。上述之偏光板保護膜，其中該紋路較佳可更包括有複數個凸塊位於至少部分該凹槽交錯處上。In the above-mentioned polarizing plate protective film of the present invention, the grain may be a vertical and horizontal vertical staggered groove, or a groove which is staggered and staggered. The polarizing plate protective film described above, wherein the grain preferably further comprises a plurality of bumps located at least partially at the intersection of the grooves.
上述本發明之偏光板保護膜，其中該紋路可為縱橫垂直交錯的凸塊，或是為斜紋走向交錯的凸塊。上述之偏光板保護膜，其中該凸塊可為上窄下寬。In the above-mentioned polarizing plate protective film of the present invention, the grain may be a vertically and horizontally staggered bump or a staggered staggered bump. The above polarizing plate protective film, wherein the bump can be upper narrow and lower width.
應用本發明之偏光板保護膜可無須使用傳統技術中所使用的間隔墊，而縮小了放置液晶面板所需的空間。且，在提取液晶面板時不需浪費時間去處理存在於液晶面板間的間隔墊，所以可提高提取液晶面板的速度。此外，亦可以避免液晶面板間彼此相互吸附。The polarizing plate protective film of the present invention can reduce the space required for placing the liquid crystal panel without using the spacer used in the conventional art. Moreover, it is not necessary to waste time to process the spacers existing between the liquid crystal panels when extracting the liquid crystal panel, so that the speed of extracting the liquid crystal panel can be improved. In addition, it is also possible to prevent the liquid crystal panels from adsorbing each other.
根據本發明之一態樣，偏光板保護膜是貼附在液晶面板的偏光板上，偏光板保護膜的表面上設置有紋路以及平坦區。保護膜表面上的紋路可以防止保護膜與保護膜之間的彼此黏貼吸附。所以，當貼附有上述偏光板保護膜的液晶面板彼此堆疊時，不需在液晶面板之間設置間隔墊。當自動提取設備在提取液晶面板時，可以利用真空吸嘴吸引偏光板保護膜表面的平坦區，而完成自動提取的動作。According to an aspect of the invention, the polarizing plate protective film is attached to the polarizing plate of the liquid crystal panel, and the surface of the polarizing plate protective film is provided with a grain and a flat region. The texture on the surface of the protective film prevents adhesion between the protective film and the protective film. Therefore, when the liquid crystal panels to which the above-described polarizing plate protective film is attached are stacked on each other, it is not necessary to provide a spacer between the liquid crystal panels. When the automatic extraction device extracts the liquid crystal panel, the vacuum nozzle can be used to attract the flat region of the surface of the polarizing plate protection film to complete the automatic extraction operation.
在本發明之一實施例中，上述偏光板保護膜的平坦區域是由該紋路所圍繞而成，且其長寬不小於約2公分。In an embodiment of the invention, the flat region of the polarizing plate protective film is surrounded by the grain and has a length and a width of not less than about 2 cm.
