Abstract
Description
本創作係關於一種導光元件,尤指應用於背光模組以及顯示裝置之導光膜及其應用。This creation is about a kind of light guide element, especially light guide film applied to backlight module and display device and its application.
現今之顯示裝置主要係利用一背光模組對顯示面板提供背光源,藉此使所述顯示裝置能顯示出畫面以供使用者檢視,而所述背光模組則係在一導光膜的入光面鄰設一光源,所述導光膜上的光學微結構能反射所述光源打入的光,使光從所述導光膜的出光面出光。The current display device mainly uses a backlight module to provide a backlight source to the display panel, so that the display device can display images for users to view, and the backlight module is a light guide film. A light source is arranged adjacent to the light surface, and the optical microstructure on the light guide film can reflect the light input by the light source, so that the light is emitted from the light exit surface of the light guide film.
其中,所述背光模組之導光膜上會設有一微結構區及一環繞該佈點區之空白區,所述光學微結構係塗佈於該導光膜之微結構區。而為了避免導光膜於製造後,運輸至組裝區的過程中,所述導光膜上的光學微結構受損,會將一離型紙貼附於該導光膜上,待作業人員欲組裝背光模組時,作業人員必須先剝離所述黏附於導光膜上之離型紙,才能進行所述導光膜之設置作業。Wherein, the light guide film of the backlight module is provided with a microstructure area and a blank area surrounding the dotted area, and the optical microstructure is coated on the microstructure area of the light guide film. In order to prevent the optical microstructure on the light guide film from being damaged during the transportation to the assembly area after the light guide film is manufactured, a release paper is attached to the light guide film until the operator wants to assemble it When the backlight module is used, the operator must first peel off the release paper adhered to the light guide film before setting up the light guide film.
由於分布在所述導光膜之微結構區外圍的空白區為平整表面,當所述離型紙貼附於所述導光膜上時,貼附於所述導光膜之空白區部分之離型紙會較難剝離,故現今作業人員在剝離所述離型紙時,會使用一膠帶先貼附於所述離型紙上,並透過拉動所述膠帶使所述離型紙脫離所述導光膜,然而如前述,作業人員在剝離所述離型紙的作業中,必須先取用一段膠帶才能剝離所述離型紙,不但在作業上有所不便,且在剝離所述離型紙後,導光膜上容易所述導光膜有殘膠的問題發生。Since the blank area distributed on the periphery of the microstructure area of the light guide film is a flat surface, when the release paper is attached to the light guide film, the part of the blank area attached to the light guide film is separated The mold paper is more difficult to peel off. Therefore, when peeling the release paper, the workers now use an adhesive tape to attach the release paper first, and pull the tape to remove the release paper from the light guide film. However, as mentioned above, in the operation of peeling the release paper, the operator must first take a piece of tape before peeling off the release paper. Not only is there inconvenience in the operation, but also after the release paper is peeled off, the light guide film is easy The light guide film has a problem of residual glue.
