图2是本发明显示面板的第一实施例的俯视示意图，图3是沿图2中C-C线的剖视图。请参阅图2及图3，本发明显示面板2包括一显示区20及一透光区30。所述显示区20指的是能够显示画面的区域；所述透光区30指的是能够允许可见光穿透的区域，即在透光区30，可见光能够自显示面板2的出光面照射至显示面板2的非出光面。所述显示区20包围所述透光区30，即所述透光区30的边界独立于所述显示区20的边界。
所述显示面板2包括多个膜层。所述多个膜层中的至少一膜层具有一无成膜区。在本实施例中，所述显示面板2包括一薄膜晶体管层21、设置在所述薄膜晶体管层21上的一有机发光器件层22及覆盖所述有机发光器件层22的一薄膜封装层23，其中，所述有机发光器件层22具有一无成膜区22A。所述无成膜区22A指的是在该区域不形成所述有机发光器件层。具体地说，在制备所述有机发光器件层22的工艺中，在一预定区域不形成有机发光器件层22，该预定区域即为所述无成膜区22A。
在垂直所述显示面板2的方向，所述无成膜区的正投影与所述透光区30的正投影重叠。也就是说，所述透光区30的正投影在所述无成膜区的正投影的范围内，即所述无成膜区的正投影与所述透光区30的正投影重合或者所述无成膜区的正投影的边缘突出于所述透光区30的正投影的边缘。具体地说，在本实施例中，在Y方向上，所述无成膜区22A的正投影与所述透光区30的正投影。所述无成膜区22A的正投影与所述透光区30的正投影重叠指的是所述无成膜区22A的正投影与所述透光区30的正投影重合或者所述无成膜区22A的正投影的边缘突出于所述透光区30的正投影的边缘。由于在所述透光区30对应的区域并未形成所述有机发光器件层22，则可见光能够自显示面板2的出光面照射至显示面板2的非出光面，从而能够为显示面板非出光侧的功能器件提供可见光。
可选地，在本实施例中，所述显示面板2还包括一偏光片24。所述偏光片24设置在所述膜层之上。具体地说，所述偏光片24设置在所述薄膜封装层23之上。所述偏光片24具有一开口24A，其中，在制备显示面板2的工艺中，可采用激光切割的方法形成所述开口24A。在垂直所述显示面板2的方向，所述开口24A的正投影与所述透光区30的正投影重叠。也即是说，在Y方向，所述开口24A的正投影与所述透光区30的正投影重合或者所述开口24A的正投影的边缘突出于所述透光区30的正投影的边缘。即所述透光区30并未被所述偏光片24遮挡，可见光能够自所述偏光片24的开口24A穿过。
其中，在本实施例中，所述偏光片24的所述开口24A的宽度W1小于所述有机发光器件层22的无成膜区22A的宽度W2，从而可进一步避免所述有机发光器件层22对所述透光区30的遮挡。
所述显示面板2还包括一衬底25及一盖板26，所述衬底25设置在所述薄膜晶体管层21之下，所述盖板26覆盖所述膜层。具体地说，在本实施例中，所述盖板26覆盖所述偏光片25。所述衬底25为常规的衬底，例如PI衬底，所述盖板26为透光盖板，例如玻璃盖板。
本发明显示面板在透光区30将多个膜层中的至少一膜层设置无成膜区，由于在透光区30缺少一膜层的遮挡，其可见光的透光率大大增加，从而便于位于显示面板非出光侧的功能器件采光。
图4是本发明显示面板的第二实施例的剖视图。请参阅图4，在该实施例中，所述显示面板2包括一薄膜晶体管层21、设置在所述薄膜晶体管层21上的一有机发光器件层22及覆盖所述有机发光器件层22的一薄膜封装层23。本实施例与第一实施例的区别在于，所述有机发光器件层22具有一无成膜区22A，所述薄膜封装层23具有一无成膜区23A。所述无成膜区22A指的是在该区域不形成所述有机发光器件层22，所述无成膜区23A指的是在该区域不形成所述薄膜封装层23。
其中，所述有机发光器件层22的无成膜区22A的宽度W2大于所述薄膜封装层23的无成膜区23A的宽度W4。具体地说，所述薄膜封装层23能够覆盖所述有机发光器件层22的表面及朝向无成膜区22A的边缘，以保护有机发光器件层22中的结构不受空气中的水汽和氧气侵蚀。
图5是本发明显示面板的第三实施例的剖视图。请参阅图5，在该实施例中，所述显示面板2包括一薄膜晶体管层21、设置在所述薄膜晶体管层21上的一有机发光器件层22及一覆盖所述有机发光器件层22的薄膜封装层23。本实施例与第一实施例的区别在于，所述有机发光器件层22具有一无成膜区22A，所述薄膜封装层23具有一无成膜区23A，所述薄膜晶体管层21具有一无成膜区21A。所述无成膜区22A指的是在该区域不形成所述有机发光器件层22，所述无成膜区23A指的是在该区域不形成所述薄膜封装层23，所述无成膜区21A指的是在该区域不形成所述薄膜晶体管层21。
其中，在本实施例中，所述有机发光器件层22的无成膜区22A的宽度W2大于所述薄膜封装层23的无成膜区23A的宽度W4，所述薄膜封装层23的无成膜区23A的宽度W4大于所述薄膜晶体管层21的无成膜区21A的宽度W5。从而使得所述有机发光器件层22上表面、下表面及边缘均被包围，以保护有机发光器件层22中的结构不受空气中的水汽和氧气侵蚀。
可选地，在本实施例中，所述显示面板2还包括一衬底25。所述衬底25设置在所述薄膜晶体管层21之下。所述衬底25具有一开口25A，在垂直所述显示面板2的方向，所述衬底25的所述开口25A的正投影与所述透光区30的正投影重叠。也即是说，在Y方向，所述衬底25的所述开口25A的正投影与所述透光区30的正投影重合或者所述衬底25的所述开口25A的正投影的边缘突出于所述透光区30的正投影的边缘。即所述透光区30并未被所述衬底25遮挡，可见光可自所述衬底25的开口25A穿过。
其中，在本实施例中，所述偏光片24的开口24A的宽度W1小于所述有机发光器件层22的无成膜区22A的宽度W2，从而可进一步避免所述有机发光器件层22对所述透光区30的遮挡。所述衬底25的开口25A的宽度W3小于所述有机发光器件层22的无成膜区22A的宽度W2，从而可进一步避免所述有机发光器件层22对所述透光区30的遮挡，在制备所述显示面板时，可在同一工序中采用激光切割的方法形成所述衬底的开口25A及所述偏光片的开口24A，则所述衬底的开口25A的宽度W3与所述偏光片的开口24A的宽度W1相等。
可选地，在本实施例中，所述偏光片24的开口24A的宽度W1小于所述薄膜晶体管层21的无成膜区21A的宽度W5，所述衬底25的开口25A的宽度W3小于所述薄膜晶体管层21的无成膜区21A的宽度W5，从而避免显示面板2的各个膜层遮挡所述透光区30。
所述薄膜晶体管层21的结构为常规结构，其可由至少一金属层（附图中未绘示）及至少一绝缘层（附图中未绘示）形成。在本实施例中，所述金属层绕过与所述透光区30对应的区域，以形成所述薄膜晶体管层21的无成膜区21A。由于所述绝缘层为透明材质制成，其允许可见光通过，而金属层不允许可见光通过，则在所述无成膜区21A可设置有所述绝缘层，而未设置所述金属层，从而避免所述金属层对可见光的遮挡。在本发明另一实施例中，在所述无成膜区21A既没有设置所述金属层，也没有设置所述绝缘层，从而进一步增加透光区30的可见光透光率。
本发明还提供一种显示装置。图6是本发明显示装置的结构示意图。请参阅图6，本发明显示装置包括上述的显示面板2及一功能器件3。所述功能器件3设置在所述显示面板2的非出光面侧。在所述功能器件3朝向所述显示面板2的一侧，所述功能器件3具有一采光区3A。在垂直所述显示面板2的方向，所述透光区30的正投影与所述采光区3A的正投影重叠。具体地说，在本实施例中，所述功能器件3为一摄像头组件，所述采光区3A为所述摄像头组件的镜头，所述透光区30的正投影与所述采光区3A的正投影重叠，以保证所述摄像头组件的镜头能够完全位于透光区30，从而保证进入所述摄像头组件的镜头的可见光的强度。在本发明其他实施例中，所述功能器件3也可以为其他需要可见光的结构，本发明对此不进行限定。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
