随着信息传输技术与电子产品的发展，有机发光二极管(organic light- emitting diode，OLED)显示装置应用越来越广泛。现有的柔性OLED显示屏应用于平面显示装置时，主要包括以下两类实现方法：应用在平面显示装置的一个平面（或者一个平面以及平板手机装置的侧棱边），而另外一个平面没有显示屏，即单面显示的应用；应用于动态弯折平面显示装置，主要受显示面可以折叠，从而实现打开/折叠平面显示装置的显示屏表面，即单面动态弯折的应用，但此项技术目前处于开发阶段。

 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本揭示可用以实施的特定实施例。本揭示所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]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，结构相似的单元是用以相同标号表示。
本揭示针对现有技术的OLED显示装置屏占比低、OLED显示屏柔性特性体现度低且需使用双摄像头实现前后拍照的技术问题，本实施例能够解决该缺陷。
如图1a所示，本揭示实施例提供一种OLED显示屏100，所述OLED显示屏100包括第一显示区101、第二显示区102及第三显示区103，其中，所述第一显示区101与所述第二显示区102分别设置于所述第三显示区103的相对两侧，所述第三显示区103为可弯折折叠区，使得所述第一显示区101与所述第二显示区102能够沿着所述第三显示区103的中心线位置A-A分别朝相反方向进行折叠。所述第一显示区101与所述第二显示区102的平面形状相同，均为矩形。然而所述第一显示区101与所述第二显示区102的平面形状不应局限于本实施例中的矩形形状，而应当与其应用的OLED显示装置10的正面、背面的形状保持相同即可。
所述OLED显示屏100的衬底基板使用聚酰亚胺材料制作而成，使得所述OLED显示屏100具有较高的可弯曲特性，当然，所述OLED显示屏100也可使用其他柔性材料制作而成，例如塑料等，本揭示实施例不应以此为限。
所述第二显示区102的顶部中间位置设置有一缺口1021，即此时所述缺口1021设置于所述OLED显示屏100的正面。所述缺口1021的形状为U形。然而，所述缺口1021放置的位置不仅仅局限于图1a中所述缺口的位置，也可将所述缺口1021放置在所述第二显示区102的任意位置，所述缺口1021的位置及大小可根据具体需求进行调整。为了不影响用户对所述平面显示屏100的观赏效果，一般将所述缺口1021放置于所述第二显示区102的右上角、左上角位置及顶端中部位置。进一步地，所述缺口1021也可设置于所述第一显示区101内，即此时所述缺口1021设置于所述OLED显示屏100的背面，在此不再详述。
如图1b、图1c所示，所述缺口1021的形状不仅仅局限于U形，还可为水滴形、圆孔形或其他形状，或者，所述OLED显示屏100可取消所述缺口1021的设置，即所述OLED显示屏100内未设置任何镂空结构的平面。本揭示实施例以所述缺口1021的形状为U形的所述OLED显示屏100为例进行阐述说明。
所述OLED显示屏100为具有完整结构的柔性OLED显示屏，包括衬底基板、OLED发光层、封装层、柔性触摸屏等结构，在此不再一一详述。
如图2所示，将所述第一显示区101与所述第二显示区102沿所述第三显示区103的中心线位置A-A分别朝相反方向进行折叠后，所述第一显示区101与所述第二显示区102分别处于两个平面，其中，所述第二显示区102位于所述OLED显示屏100的正面，所述第一显示区101位于所述OLED显示屏100的背面，同时，所述第三显示区103位于所述OLED显示屏100的侧面。
如图3所示，本揭示实施例提供一种OLED显示装置10，所述OLED显示装置包括支撑结构200以及设置于所述支撑结构200表面的所述OLED显示屏100，所述支撑结构200用来放置电池、电路板以及固定所述OLED显示屏100；其中，所述OLED显示屏100包括所述第一显示区101、所述第二显示区102及所述第三显示区103，其中，所述第一显示区101与所述第二显示区102分别设置于所述第三显示区103的相对两侧，所述第三显示区103为可弯折折叠区，使得所述第一显示区101与所述第二显示区102能够沿着所述第三显示区103的中心线位置A-A分别朝相反方向进行折叠。折叠之后，所述第二显示区102贴附于所述支撑结构200的正面，所述第一显示区101贴附于所述支撑结构200的背面，所述第三显示区103贴附于所述支撑结构200的其中一条侧棱201处。
由于本揭示实施例提供的所述OLED显示装置10的所述支撑结构200的所述侧棱201的形状为圆弧状，因此，所述OLED显示屏100折叠后，所述第三显示区103的形状同样为圆弧状。但本揭示实施例不应以此为限，例如，所述支撑结构200的所述侧棱201的形状也可为其他平滑的形状。
在本揭示实施例中，所述第二显示区102上远离所述第三显示区103的一边设置有一柔性电路板104，所述柔性电路板104电连接所述第二显示区102。即在图3中，所述第二显示区102固定在所述支撑结构200的正面，所述柔性电路板104固定于所述支撑结构200的一条长边处，所述柔性电路板104沿着所述支撑结构200的该长边进行弯折，从所述支撑结构200的正面绕到其背面，之后所述柔性电路板104紧贴附于所述支撑结构200的背面，同时，所述第一显示区101贴附于所述支撑结构200的背面并压覆于所述柔性电路板104之上。其中，所述柔性电路板104的弯折半径取决于所述OLED显示装置10的厚度，具体地，当所述OLED显示装置10的厚度较大时，所述柔性电路板104的弯折半径较大；当所述OLED显示装置10的厚度较小时，所述柔性电路板104的弯折半径较小。同时，可薄化所述柔性电路板104的局部厚度，以减小所述柔性电路板104弯折后其表面金属线的应力，进而减小所述表面金属线的断裂风险，提高所述OLED显示装置10的使用寿命。
同理，还可将所述第一显示区101远离所述第三显示区103的一边设置有所述柔性电路板104，所述柔性电路板104电连接所述第一显示区101。将所述柔性电路板104固定于所述支撑结构200的一条长边处，所述柔性电路板104沿着所述支撑结构200的该长边进行弯折，从所述支撑结构200的背面绕到其正面，之后所述柔性电路板104紧贴附于所述支撑结构200的正面。与此同时，所述第二显示区102贴附于所述支撑结构200的正面并压覆于所述柔性电路板104之上。
进一步地，所述第一显示区101与所述第二显示区102在各自远离所述第三显示区103的一边也可同时设置有一个所述柔性电路板104，两个所述柔性电路板104分别电连接所述第一显示区101与所述第二显示区102。
进一步地，在所述柔性电路板104上设置有一集成电路芯片（Integrated Circuit，IC）105，以实现所述OLED显示屏100与所述支撑结构200的电连接，使得所述OLED显示屏100能够显示图像内容。所述第一显示区101、所述第二显示区102以及所述第三显示区103均能显示图像内容，使得所述OLED显示装置10的屏占比趋向100%，更好地实现了所述OLED显示装置10的全面显示功能。其中，所述第一显示区101与所述第二显示区102为主显示区，用于显示主要图像内容；所述第三显示区103为辅显示区，用于显示微小图形，例如所述OLED显示装置10的使用状态（充电、待机、通讯网络信号强度等）。所述第一显示区101与所述第二显示区102可显示相同或相异图像，例如，在显示不同图像时将不同图像信号分别驱动至所述第一显示区101和所述第二显示区102，在显示相同图像时将相同图像信号分别驱动至所述第一显示区101和所述第二显示区102。因此，所述第一显示区101与所述第二显示区102所显示的图像内容可以进行自由切换，即所述第一显示区101的显示图像内容可切换到所述第二显示区102的显示图像内容，或者所述第二显示区102的显示图像内容可切换到所述第一显示区101的显示图像内容，以实现所述OLED显示装置10的正面、背面的显示画面的切换。同时，由于所述第一显示区101与所述第二显示区102共用一个所述柔性电路板104，且两者显示面积相同，分辨率也相同，因此能够实现同样等级的画面质量。
进一步地，在固定所述柔性电路板104之后，为了保证所述支撑结构200的表面平整度，可在所述支撑结构200的背面设置一具有一定深度的凹槽（图中未示出），将所述柔性电路板104固定于所述凹槽内；也可在所述柔性电路板104上设置一层缓冲层（图中未示出），所述缓冲层的材料可选泡棉。
由于所述OLED显示屏100仅设置有一个所述缺口，当所述第三显示区103折叠完成之后，通过所述缺口1021露出所述OLED显示屏100背面的摄像头202及语音装置203，以实现拍照及播放语音的功能。也就是说所述支撑结构显示装置10仅设置一个摄像头202即可满足前后拍照需求，当用户进行拍照时，将所述缺口1021对准被拍照物体即可进行拍照操作，避免了同时使用前置摄像头和后置摄像头的情况，有利于提高屏占比及节约生产成本。
如图4所示，为本揭示实施例提供的第2种缺口形状为U形的OLED显示屏300折叠前的结构示意图，在位于第一显示区301和第二显示区302内之间的第三显示区303的上部、下部均设置有另一缺口3022，所述缺口3021为U形，使得在所述第一显示区301和所述第二显示区302的两个角都为圆角，进而使得所述第一显示区301和所述第二显示区301的四个角都可以实现圆角显示。同时，对所述OLED显示屏300采用与所述OLED显示屏100相同的弯折&固定方法，所述弯折&固定方法如前所叙述，在此不再重复描述。
所述OLED显示装置10可以为OLED面板、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
有益效果为：本揭示提供的OLED显示装置，通过将第一显示区与第二显示区配置成用于沿第三显示区和分别朝向相反的方向弯折，使得第一显示区、第二显示区及第三显示区均可实现显示，从而使得OLED显示装置具有更高的屏占比，该OLED显示装置的正面、背面可显示不同的内容，且所显示的内容可自由切换，同时仅需一个摄像头即可满足拍照要求，避免同时使用双摄像头的情况。
综上所述，虽然本揭示已以优选实施例揭露如上，但上述优选实施例并非用以限制本揭示，本领域的普通技术人员，在不脱离本揭示的精神和范围内，均可作各种更动与润饰，因此本揭示的保护范围以权利要求界定的范围为准。
