一般來說，習知可撓性顯示器會透過樹脂層來覆蓋顯示面板的顯示區，而且會與位於其上的感壓膠層直接接觸。然而，感壓膠層與樹脂層之間因為材料特性不同因而導致二者之間的接觸界面附著性不佳。因此，當可撓性顯示器在撓曲時，在感壓膠層與樹脂層的界面上容易產生剝離現象(peeling effect)，進而降低可撓性顯示面板的結構可靠度。In general, a conventional flexible display covers a display area of a display panel through a resin layer and is in direct contact with a pressure sensitive adhesive layer located thereon. However, the contact interface between the pressure-sensitive adhesive layer and the resin layer is poor due to the difference in material properties. Therefore, when the flexible display is flexed, a peeling effect is likely to occur at the interface between the pressure sensitive adhesive layer and the resin layer, thereby reducing the structural reliability of the flexible display panel.

為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the invention will be apparent from the following description.
圖1繪示為本發明的一實施例的一種顯示器的剖面示意圖。請參考圖1，本實施例的顯示器100包括一可撓性疊層結構200以及一可撓性顯示單元300，其中可撓性疊層結構200配置於可撓性顯示單元300上。此處，可撓性顯示單元300例如為一電泳顯示面板或OLED顯示面板，但並不以此為限。FIG. 1 is a cross-sectional view of a display according to an embodiment of the invention. Referring to FIG. 1 , the display 100 of the present embodiment includes a flexible laminate structure 200 and a flexible display unit 300 , wherein the flexible laminate structure 200 is disposed on the flexible display unit 300 . Here, the flexible display unit 300 is, for example, an electrophoretic display panel or an OLED display panel, but is not limited thereto.
詳細來說，本實施例的顯示器100的可撓性疊層結構200包括一第一保護層210、一第二保護層220以及一可撓性材料層230。第一保護層210直接接觸可撓性顯示單元300。第二保護層220直接接觸第一保護層210且具有多個開口222，其中開口222暴露出部分第一保護層210。可撓性材料層230配置於第二保護層220上，且延伸至開口222內，並直接接觸開口222所暴露出的第一保護層210。特別是，可撓性材料層230與第一保護層210之間的黏著力大於第二保護層220與第一保護層210之間的黏著力，藉此在可撓性顯示單元300撓曲時可分散可撓性材料層230對第一保護層210的拉力，使得第一保護層210與第二保護層220不易因撓曲而導致在界面上分離，減少剝離現象的產生。In detail, the flexible laminate structure 200 of the display 100 of the present embodiment includes a first protective layer 210, a second protective layer 220, and a flexible material layer 230. The first protective layer 210 directly contacts the flexible display unit 300. The second protective layer 220 directly contacts the first protective layer 210 and has a plurality of openings 222, wherein the openings 222 expose a portion of the first protective layer 210. The flexible material layer 230 is disposed on the second protective layer 220 and extends into the opening 222 and directly contacts the first protective layer 210 exposed by the opening 222. In particular, the adhesion between the flexible material layer 230 and the first protective layer 210 is greater than the adhesion between the second protective layer 220 and the first protective layer 210, thereby deflecting the flexible display unit 300. The tension of the first protective layer 210 can be dispersed by the flexible material layer 230, so that the first protective layer 210 and the second protective layer 220 are less likely to be separated at the interface due to deflection, thereby reducing the occurrence of peeling.
更具體來說，本實施例的可撓性材料層230具體化為一感壓膠(PSA)層，覆蓋第二保護層220並填滿開口222。再者，本實施例的可撓性疊層結構200更包括一圖案化金屬層240，其中圖案化金屬層240配置於第二保護層220的一上表面221與可撓性材料層230之間。此處，圖案化金屬層240於第一保護層210上的正投影與第二保護層220的上表面221於第一保護層210上的正投影完全重疊，且圖案化金屬層240與第二保護層220共形設置。More specifically, the flexible material layer 230 of the present embodiment is embodied as a pressure sensitive adhesive (PSA) layer covering the second protective layer 220 and filling the opening 222. Moreover, the flexible laminated structure 200 of the present embodiment further includes a patterned metal layer 240, wherein the patterned metal layer 240 is disposed between an upper surface 221 of the second protective layer 220 and the flexible material layer 230. . Here, the orthographic projection of the patterned metal layer 240 on the first protective layer 210 completely overlaps with the orthographic projection of the upper surface 221 of the second protective layer 220 on the first protective layer 210, and the patterned metal layer 240 and the second The protective layer 220 is conformally disposed.
由於本實施例的第二保護層220具有暴露出部分第一保護層210的開口222，因此當可撓性材料層230填滿開口222時，可撓性材料層230能直接接觸第一保護層210，其中可撓性材料層230與第一保護層210之間的黏著力大於第二保護層220與第一保護層210之間的黏著力。因此，可撓性顯示單元300撓曲時可分散可撓性材料層230對第一保護層210的拉力，使得第一保護層210與第二保護層220不易因撓曲而導致在界面上分離，減少剝離現象的產生。此外，由於本實施例的顯示器100包括上述的可撓性疊層結構200，因此可具有較佳的結構可靠度。Since the second protective layer 220 of the present embodiment has the opening 222 exposing a portion of the first protective layer 210, when the flexible material layer 230 fills the opening 222, the flexible material layer 230 can directly contact the first protective layer. 210, wherein an adhesive force between the flexible material layer 230 and the first protective layer 210 is greater than an adhesion between the second protective layer 220 and the first protective layer 210. Therefore, when the flexible display unit 300 is flexed, the tensile force of the flexible material layer 230 on the first protective layer 210 can be dispersed, so that the first protective layer 210 and the second protective layer 220 are not easily separated by the deflection. To reduce the occurrence of peeling. Furthermore, since the display 100 of the present embodiment includes the above-described flexible laminated structure 200, it can have better structural reliability.
圖2繪示為本發明的另一實施例的一種顯示器的剖面示意圖。請同時參考圖1與圖2，本實施例的顯示器100A與圖1中的顯示器100相似，惟二者主要差異之處在於：本實施例的可撓性疊層結構200A的可撓性材料層230A具體化為一金屬層，其覆蓋第二保護層220的上表面221與開口222的內壁223，且直接接觸開口222所暴露出的第一保護層210，並具有多個暴露出第二保護層220之部分上表面221的接觸開口224。此外，本實施例的可撓性疊層結構200A更包括一壓力膠層240A，配置於可撓性材料層230A上，且透過接觸開口224直接接觸第二保護層220。壓力膠層240A配置於可撓性材料層230A上，覆蓋可撓性材料層230A並填滿開口222及直接接觸位於開口222內的可撓性材料層230A。2 is a cross-sectional view of a display according to another embodiment of the present invention. Referring to FIG. 1 and FIG. 2 simultaneously, the display 100A of the present embodiment is similar to the display 100 of FIG. 1, but the main difference is that the flexible material layer of the flexible laminated structure 200A of the present embodiment 230A is embodied as a metal layer covering the upper surface 221 of the second protective layer 220 and the inner wall 223 of the opening 222, and directly contacting the first protective layer 210 exposed by the opening 222, and having a plurality of exposed second A contact opening 224 of a portion of the upper surface 221 of the protective layer 220. In addition, the flexible laminate structure 200A of the present embodiment further includes a pressure adhesive layer 240A disposed on the flexible material layer 230A and directly contacting the second protective layer 220 through the contact opening 224. The pressure adhesive layer 240A is disposed on the flexible material layer 230A, covers the flexible material layer 230A and fills the opening 222 and directly contacts the flexible material layer 230A located in the opening 222.
由於本實施例的第二保護層220具有暴露出部分第一保護層210的開口222，且可撓性材料層230A覆蓋第二保護層220的上表面221與開口222的內壁223且直接接觸開口222所暴露出的第一保護層210，其中可撓性材料層230A與第一保護層210之間的黏著力大於第二保護層220與第一保護層210之間的黏著力。因此，可撓性顯示單元300撓曲時可分散可撓性材料層230A對第一保護層210的拉力，使得第一保護層210與第二保護層220不易因撓曲而導致在界面上分離，減少剝離現象的產生。此外，由於本實施例的顯示器100A包括上述的可撓性疊層結構200A，因此可具有較佳的結構可靠度。Since the second protective layer 220 of the present embodiment has the opening 222 exposing a portion of the first protective layer 210, and the flexible material layer 230A covers the upper surface 221 of the second protective layer 220 and is in direct contact with the inner wall 223 of the opening 222 The first protective layer 210 exposed by the opening 222, wherein the adhesive force between the flexible material layer 230A and the first protective layer 210 is greater than the adhesion between the second protective layer 220 and the first protective layer 210. Therefore, when the flexible display unit 300 is flexed, the tensile force of the flexible material layer 230A on the first protective layer 210 can be dispersed, so that the first protective layer 210 and the second protective layer 220 are not easily separated by the deflection. To reduce the occurrence of peeling. Furthermore, since the display 100A of the present embodiment includes the above-described flexible laminated structure 200A, it can have better structural reliability.
值得一提的是，本發明並不限定可撓性疊層結構200、200A的結構形態，只要可撓性材料層230、230A與第一保護層210之間的黏著力大於第二保護層220與第一保護層210之間的黏著力，皆屬於本發明所欲保護的範圍。It should be noted that the present invention does not limit the structural form of the flexible laminated structure 200, 200A, as long as the adhesive force between the flexible material layers 230, 230A and the first protective layer 210 is greater than the second protective layer 220. The adhesion to the first protective layer 210 is within the scope of the present invention.
綜上所述，在本發明的可撓性疊層結構中，由於可撓性材料層與第一保護層之間的黏著力大於第二保護層與第一保護層之間的黏著力，因此在撓曲時可分散可撓性材料層對第一保護層產生的拉力，以減少剝離現象的產生。另外，本發明的顯示器包括上述的可撓性疊層結構，可具有較佳的結構強度。In summary, in the flexible laminated structure of the present invention, since the adhesive force between the flexible material layer and the first protective layer is greater than the adhesion between the second protective layer and the first protective layer, The tensile force generated by the layer of the flexible material on the first protective layer can be dispersed during flexing to reduce the occurrence of peeling. Additionally, the display of the present invention includes the flexible laminate structure described above and may have better structural strength.
