Title
(EN) POLARIZER PROTECTIVE FILM AND PEEL-OFF METHOD THEREFOR
(FR) FILM PROTECTEUR DE POLARISEUR ET SON PROCÉDÉ DE PELAGE
(ZH) 偏光片保护膜及其撕揭方法
Abstract
(EN)
A polarizer protective film (1) and a peel-off method therefor. The polarizer protective film (1) is adhered to the surface of a polarizer body (2). The polarizer protective film (1) is provided with an extending portion (11) protruding from the polarizer body (2). The extending portion (11) provided on the polarizer protective film (2) provides a good force-bearing point when peeling off the polarizer protective film (1), achieving the effect of peeling off the polarizer protective film (1) in one step.
(FR)
Cette invention concerne un film protecteur de polariseur (1) et son procédé de pelage. Le film protecteur de polariseur (1) est collé à la surface d'un corps de polariseur (2). Le film protecteur de polariseur (1) est pourvu d'une partie d'extension (11) faisant saillie à partir du corps de polariseur (2). La partie d'extension (11) disposée sur le film de protection de polariseur (2) fournit un bon point d'appui de force lors du pelage du film de protection de polariseur (1), ce qui permet d'obtenir l'effet de pelage du film de protection de polariseur (1) en une seule étape.
(ZH)
一种偏光片保护膜(1)及其撕揭方法,偏光片保护膜(1)黏覆于偏光片本体(2)的表面,偏光片保护膜(1)设有延伸部(11),突出于所述偏光片本体(2)。通过在偏光片保护膜(2)设置延伸部(11),使得在撕下偏光片保护膜(1)时,有一个很好的受力点,达到一次性撕除下偏光片保护膜(1)的效果。
