Title (EN) SCREEN FILM
(FR) FILM D'ÉCRAN
(ZH) 屏幕贴膜
Abstract:
(EN) A screen film comprises the following layers sequentially arranged from top to bottom: an optical clear adhesive (OCA) layer (1000); a substrate layer (2000) serving as a supporting member; and an attachment layer (3000) for bonding to a curved screen. The attachment layer (3000) is provided with a bonding surface (3100) for bonding to the curved screen. The bonding surface (3100) is a smooth curved surface with a curve matching a curve of the curved screen. The screen film can be closely bonded to the curved screen by means of the bonding surface (3100) with no gap existing therebetween. Moreover, a middle portion of the bonding surface (3100) is not suspended. When bonded to the curved screen, an edge of the screen film does not rise up. The screen film does not deform even when pressed hard.
(FR) L’invention concerne un film d'écran qui comporte les couches suivantes, disposées séquentiellement de haut en bas : une couche d'adhésif transparent optique (OCA) (1000) ; une couche de substrat (2000) servant d'élément support ; une couche de fixation (3000) afin de coller à un écran incurvé. La couche de fixation (3000) est munie d'une surface de collage (3100) afin de coller à l'écran incurvé. La surface de collage (3100) est une surface incurvée lisse ayant une courbe correspondant à la courbe de l'écran incurvé. Le film d'écran peut être étroitement collé à l'écran incurvé au moyen de la surface de collage (3100) sans présenter d'interstices entre eux. De plus, une partie centrale de la surface de collage (3100) n'est pas suspendue. Lorsqu'il est collé à l'écran incurvé, un bord du film d'écran ne se décolle pas. Le film d'écran ne se déforme pas même lorsqu'il est soumis à une forte pression.
(ZH) 一种屏幕贴膜,包括自上至下依次设置的OCA光学胶层(1000)、作为承载体的基材层(2000)和用于贴合在曲面屏上的吸附层(3000);所述吸附层(3000)上设置有用于贴合在所述曲面屏上的贴合面(3100);所述贴合面(3100)为一光滑曲面,且所述贴合面(3100)上设置有与所述曲面屏相匹配的弧度。该屏幕贴膜,通过贴合面(3100)可以紧密地与曲面屏相贴合,使两者之间可以消除缝隙,同时,贴合面(3100)的中间部分也不会出现悬空的状态。屏幕贴膜贴合于曲面屏上,其边缘不会发生飘起,即使大力按压屏幕贴膜时,屏幕贴膜也不会产生变形。
