 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本揭示可用以实施的特定实施例。
为了让本揭示的上述及其他目的、特征、优点能更明显易懂，下文将特举本揭示优选实施例，并配合所附图式，作详细说明如下。再者，本揭示所提到的方向用语，例如上、下、顶、底、前、后、左、右、内、外、侧层、周围、中央、水平、横向、垂直、纵向、轴向、径向、最上层或最下层等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本揭示，而非用以限制本揭示。
在图中，结构相似的单元是以相同标号表示。
参照图1，本揭示的一实施例的一覆盖窗结构100包括柔性覆盖窗层110以及玻璃层130。柔性覆盖窗层110设置于玻璃层130上。本实施例通过覆盖窗层110以及玻璃层130有效提升覆盖窗结构100的硬度和可弯折性。这样可确保覆盖窗结构100的弯折性、硬度和抗冲击性。
具体而言，本揭示的实施例的覆盖窗结构100结合了玻璃层130具有高硬度和良好抗冲击性能以及柔性覆盖窗层110具有良好弯折性和不易破裂的优点，从而兼顾弯折性、硬度和抗冲击性，可提升覆盖窗结构100的的信赖性。
参照图2，本揭示的一实施例的覆盖窗结构100还包括第一光学胶层120。柔性覆盖窗层110、第一光学胶层120和玻璃层130由上而下依序设置及贴合，使得覆盖窗结构100包括多层复合结构。
由于本实施例的柔性覆盖窗层110与玻璃层130复合，柔性覆盖窗层110与玻璃层130之间用第一光学胶层120固定，形成多层复合结构，有效提升覆盖窗结构100的硬度和可弯折性。此外，柔性覆盖窗层110、第一光学胶层120和玻璃层130由上而下依序设置及贴合，即，柔性覆盖窗层110设置于覆盖窗结构100的外侧，玻璃层130设置于覆盖窗结构100的内侧，也避免了玻璃层130弯折碎裂的风险。可以理解，在其他实施例中，也可通过将柔性覆盖窗层110直接涂覆在玻璃层130上形成复合结构，而不需要第一光学胶层120，如图1的实施例。
具体地，柔性覆盖窗层110是塑料覆盖窗层。第一光学胶层120是OCA光学胶层(optically clear adhesive layer)。第一光学胶层120的厚度小于或等于20um。
本实施例的柔性覆盖窗层110设置于覆盖窗结构100的外侧，因此无油墨段差需克服，第一光学胶层120的厚度可以小于或等于20um，避免第一光学胶层120厚度过大导致覆盖窗结构100的硬度太低。此外，玻璃层130的硬度较大，可以实现支撑作用，也可有效提升覆盖窗结构100的硬度。玻璃层130设置于覆盖窗结构100的内侧，也可避免弯折中潜在的玻璃碎裂伤人的危险。
参照图3，本揭示的一实施例的覆盖窗结构100还包括第二光学胶层140及油墨层150。油墨层150设置在玻璃层130的端部并位于玻璃层130远离第一光学胶层120的一侧，第二光学胶层140设置在油墨层150之间。
由于本揭示的实施例中，柔性覆盖窗层110、第一光学胶层120、玻璃层130和第二光学胶层140由上而下依序设置及贴合，因此可更加避免了玻璃层130弯折碎裂的风险及避免弯折中潜在的玻璃碎裂伤人的危险。于本揭示的实施例中，第二光学胶层140的作用是：在将柔性覆盖窗结构110设置在显示面板上用来保护显示面板时，直接通过用第二光学胶层140将柔性覆盖窗结构110粘贴在显示面板上。
具体地，玻璃层130的厚度大于第一光学胶层120的厚度，因此可避免第一光学胶层120厚度过大导致覆盖窗结构100的硬度太低。此外，玻璃层130的厚度大于第一光学胶层120的厚度及其硬度较大，可以实现支撑作用，也可有效提升覆盖窗结构100的硬度。
具体地，玻璃层130例如为超薄玻璃层。玻璃层130的厚度范围在30um和70um之间。
参照图4，本揭示的一实施例的柔性覆盖窗层110包括有机高分子薄膜112及硬化处理层(hard coating layer)114。硬化处理层114设置于有机高分子薄膜112上，可确保覆盖窗结构100的弯折性、硬度和抗冲击性。
具体地，在玻璃层130的表面通过涂布方式制备有机高分子薄膜112。有机高分子薄膜112的厚度范围在30um和50um之间。有机高分子薄膜112为无色透明聚酰亚胺薄膜(colorless transparent polyimide film, CPI film)。
具体地，在有机高分子薄膜112的表面通过涂布方式沉积硬化处理层114。硬化处理层114的厚度范围在10um和30um之间。硬化处理层114的材料包括丙烯酸(Acryl)、硅烷(Silane)、氨基甲酸酯系(Urethane)或环氧(Epoxy)。
参照图5-6，本揭示的一实施例中，硬化处理层114包括多个凹槽116(参照图5)或多个突起结构118(参照图6)，硬化处理层114的凹槽116或突起结构118接触玻璃层130。
在本实施例中，为了提升玻璃层130与有机高分子薄膜112之间的附着力，在沉积有机高分子薄膜112之前通过蚀刻方式形成一些凹槽116或突起结构118。这样可以有效增加有机高分子薄膜112与玻璃层130之间的接触面积和结合力，防止弯折过程中发生剥离(peeling)现象。
参照图7，本揭示的一实施例还提供一柔性显示装置10包括上述的覆盖窗结构100以及显示面板200。覆盖窗结构100设置在显示面板200上。覆盖窗结构100设置在显示面板200的前侧(即，显示侧)以便保护显示面板200。
柔性显示装置10可以是可穿戴设备如智能手环、智能手表、虚拟现实(virtual reality, VR)设备。柔性显示装置10可以是柔性有机发光二极管(organic light emitting diode, OLED)显示器、电子书、电子报纸、手机、电脑和电视机。
