以下提供本揭露之多種不同的實施例或實例,以實現所提供之標的的不同技術特徵。下述具體實例的元件和設計用以簡化本揭露。當然,這些僅為示例,而非用以限定本揭露。舉例而言,說明書中揭示形成第一特徵結構於第二特徵結構之上方,其包括第一特徵結構與第二特徵結構形成而直接接觸的實施例,亦包括於第一特徵結構與第二特徵結構之間另有其他特徵結構的實施例,亦即,第一特徵結構與第二特徵結構並非直接接觸。此外,本揭露於各個實例中可能用到重複的參考符號及/或用字。這些重複符號或用字係為了簡化與清晰的目的,並非用以限定各個實施例及/或所述結構之間的關係。 Various embodiments or examples of the present disclosure are provided below to achieve different technical features of the provided subject matter. The components and designs of the following specific examples are used to simplify the present disclosure. Of course, these are merely examples and are not intended to limit the present disclosure. For example, the description discloses that forming the first feature structure above the second feature structure includes an embodiment in which the first feature structure and the second feature structure are formed in direct contact, and also includes the first feature structure and the second feature. There are embodiments of other characteristic structures between the structures, that is, the first characteristic structure and the second characteristic structure are not in direct contact. In addition, the present disclosure may use repeated reference symbols and / or words in various examples. These repeated symbols or words are for the purpose of simplicity and clarity, and are not intended to limit the relationship between the embodiments and / or the structures.
另外,空間相對用語,如「下」、「上」等,是用以方便描述一元件或特徵與其他元件或特徵在圖式中的相對關係。這些空間相對用語旨在包含除了圖式中所示之方位以外,裝置在使用或操作時的不同方位。裝置可被另外定位(例如旋轉90度或其他方位),而本文所使用的空間相對敘述亦可相對應地進行解釋。 In addition, spatial relative terms, such as "lower" and "upper", are used to conveniently describe the relative relationship between one element or feature and other elements or features in the drawing.

The second adhesive layer 250 is disposed above the periphery of the second film layer 240. In some embodiments, the second adhesive layer 250 forms a closed shape as seen from above. In some embodiments, the second film layer 240 contacts the optical hole protection area 212 of the first adhesive layer 220.
第11圖繪示根據本發明數個實施例之保護膜與遮蓋玻璃的剖面示意圖。如第11圖所示,將保護膜200D貼附至遮蓋玻璃100,使第二膠層250介於遮蓋玻璃100與第二膜層240之間,但不接觸遮蓋玻璃100的光學孔122。如此一來,不會發生黏膠汙染光學孔的問題,後續不需要進行額外的清潔製程。 FIG. 11 is a schematic cross-sectional view of a protective film and a cover glass according to several embodiments of the present invention. As shown in FIG. 11, the protective film 200D is attached to the cover glass 100 such that the second adhesive layer 250 is interposed between the cover glass 100 and the second film layer 240, but does not contact the optical hole 122 of the cover glass 100. In this way, the problem of contamination of the optical hole by the adhesive does not occur, and no subsequent cleaning process is required.
在一些實施例中,如第11圖所示,第二膠層250設置用以接觸印刷層120。在一些實施例中,第二膠層250與印刷層120的接著強度大於第一膠層220與第二膜層240的接著強度。在一些實施例中,第二膠層250與第二膜層240的接著強度大於第一膠層220與第二膜層240的接著強度。如此一來,在後續製程中,可撕除第一膜層210與第一膠層220,留下第二膜層240與第二膠層250繼續保護光學孔122,如第11及12圖所示。最終,再撕除第二膜層240與第 二膠層250。 In some embodiments, as shown in FIG. 11, the second adhesive layer 250 is disposed to contact the printing layer 120. In some embodiments, the bonding strength of the second adhesive layer 250 and the printing layer 120 is greater than the bonding strength of the first adhesive layer 220 and the second film layer 240. In some embodiments, the bonding strength of the second adhesive layer 250 and the second film layer 240 is greater than the bonding strength of the first adhesive layer 220 and the second film layer 240. In this way, in the subsequent process, the first film layer 210 and the first adhesive layer 220 can be removed, leaving the second film layer 240 and the second adhesive layer 250 to continue to protect the optical hole 122, as shown in FIGS. 11 and 12. Show. Finally, the second film layer 240 and the first film layer are removed again. 二 胶层 250。 Two adhesive layers 250.
