具体实施方式
下面结合附图，对本公开实施例提供的显示装置及其制作方法的具体实施方式进行详细的说明。需要说明的是本说明书所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。并且在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。此外，基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本公开保护的范围。
附图中各膜层的形状和大小不反映其在显示装置中的真实比例，目的只是示意说明本公开内容。
本公开实施例提供的显示装置，如图1所示，可以包括：中框102以及绕中框102弯折的一体化的柔性显示面板101。其中，柔性显示面板101可以包括位于中框102一侧的主显示面板区域A，位于中框102另一侧的副显示面板区域B，以及绕中框102弯折以连接主显示面板区域A和副显示面板区域B的弯折区域C。具体地，主显示面板区域A中的柔性显示面板101可以作为显示装置的主显示面板，副显示面板区域B可以作为显示装置的副显示面板，中框102位于主显示面板与副显示面板之间。并且，主显示面板和副显示面板设置为一体化的柔性显示面板101，主显示面板的出光侧和副显示面 板的出光侧相背设置。
在本公开实施例提供的显示装置中，利用柔性显示面板101的可挠性，采用一块柔性显示面板101即实现了双屏显示的功能，相较于相关技术中采用两块独立的显示面板实现双屏显示的技术方案，有效降低了成本与整机设计难度。
并且，相关技术中，主显示面板一般为彩屏，副显示面板一般为墨水屏，极大地限制了在副显示面板上可显示内容的多样性。而本公开实施例提供的显示装置中，由于主显示面板和副显示面板为一体化的柔性显示面板101，使得主显示面板和副显示面板均为彩屏，使得显示装置在彩色化、可显示的内容等诸多方面表现较佳。
在具体实施时，柔性显示面板可以包括柔性电致发光显示面板。进一步地，柔性电致发光显示面板可以包括：柔性有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板，或柔性量子点发光二极管(Quantum Dot Light Emitting Diodes，QLED)显示面板，在此不作限定。
在本公开实施例提供的显示装置中，柔性显示面板101可以通过图1中所示的方式直接绕中框102的右侧端面弯折，使得主显示面板所在的主显示面板区域A与副显示面板所在的副显示面板区域B分居中框102的上下两侧。当然，还可以通过图2所示的方式在中框102上设置开口，使弯折区域C贯穿中框102的开口。这样也可以使主显示面板区域A和副显示面板区域B分居中框102的上下两侧。
在本公开实施例提供的显示装置中，中框102的开口可以为贯穿中框102的过孔h，如图3所示。或者，中框102的开口也可以为位于中框102一端的凹槽g，如图4所示。可以理解的是，在开口为位于中框102一端的凹槽g时，对应的显示装置的剖面图与图1所示显示装置的剖面图相同，在此不做赘述。
在本公开实施例提供的显示装置中，结合图3至图5所示，中框102的开口在主显示面板区域A和弯折区域C交界线延伸方向上的长度m(如图3和图4所示)，与主显示面板区域A和弯折区域C交界线的长度n(如图5所 示)相等。这样一来，可以使得柔性显示面板101的短边(即主显示面板区域A和弯折区域C交界线延伸方向上的边)刚好与开口的左右两侧相接触，从而可有效固定柔性显示面板101。
在本公开实施例提供的显示装置中，弯折区域C对应的柔性显示面板101可以具有以下可能的实现方式，如图6所示的半圆型结构，图1和图2所示的显示装置中弯折区域C所对应的柔性显示面板101即为半圆型结构。如图7所示由一个平面和位于该平面两端的两个曲面构成的U型结构，图8和图9所示的显示装置中弯折区域C对应的柔性显示面板101即为U型结构。当然，弯折区域C也可以为其他形状，在此不做具体限定。
一般显示装置的厚度为7mm-8mm，若以8mm为例，在弯折区域C对应的柔性显示面板101采用图6所示的半圆型结构进行弯折时，则弯折的曲率半径可以为4mm。在弯折区域C对应的柔性显示面板101采用图7所示的U型结构进行弯折时，若预留出4mm厚的平面，则平面两端的两个曲面的半径可以为2mm。
目前双屏显示装置中的两块显示面板分别依靠各自的驱动电路来实现独立显示，导致成本较高，为降低成本，在本公开实施例提供的显示装置中，如图1所示，显示装置还可以包括：驱动电路103，副显示面板区域B可以包括显示区和绑定区，绑定区位于显示区远离弯折区域C一侧，驱动电路103通过绑定区与柔性显示面板101耦接，以驱动柔性显示面板101。这样通过采用一套驱动电路103来驱动由位于主显示面板区域A的主显示面板和位于副显示面板区域B的副显示面板构成的一体化的柔性显示面板101，从而降低了成本。并且，这样还可以不必在主显示面板所在的主显示面板区域A一侧设置用于单独驱动主显示面板的驱动电路，故可实现较窄的边框设计。驱动电路103可以包括驱动芯片和柔性电路板等本领域的普通技术人员所知的应该具有的部件。
在本公开实施例提供的上述显示装置中，为实现向驱动电路103供电，如图1所示，中框102具有副显示面板区域B一侧还设置有用于安装电池的 预留区域P，预留区域P在中框102的正投影与副显示面板区域B在中框102的正投影无交叠。并且，在显示装置为手机时，该预留区域P还可以安装骁龙845处理器等现有技术中常用的手机平台。
在本公开实施例提供的显示装置中，为了保护主显示面板区域A，如图1所示，显示装置还可以包括：位于主显示面板区域A背离中框102一侧的第一透明盖板104。
在本公开实施例提供的上述显示装置中，如图1所示，显示装置还可以包括：位于柔性显示面板101的各侧面、中框102的各侧面、以及副显示面板区域B背离中框102一侧连续设置的外壳105。其中，外壳105对应副显示面板区域B中显示区的位置为透明区域。这样设置，不但可以有效保护显示装置的内部构件，而且可以观看副显示面板区域B的显示画面。进一步地，为了更好地保护副显示面板区域B，如图10至图13所示，还可以包括覆盖副显示面板区域B中显示区域的第二透明盖板106。
当然，在本公开实施例提供的上述显示装置中，如图14至图17所示，还可以通过在外壳105对应副显示面板区域B中显示区的位置设置镂空图案，并设置覆盖副显示面板区域B中显示区的第二透明盖板106，以实现可观看副显示面板区域B的显示画面以及保护副显示面板区域B中的副显示面板的效果。
可以理解的是，在本公开实施例提供的显示装置中，柔性显示面板101的弯折区域C可以用于显示，为了能观看弯折区域C的显示画面，如图18至图23所示，外壳105对应弯折区域C的位置设置为透明区域。在弯折区域C不用于显示时，弯折区域C则无需设置像素(即弯折区域C无发光层)，仅需保留栅线、数据线等用于向主显示面板区域A传递经副显示面板区域B转发的由驱动电路103输出的驱动信号。
在本公开实施例提供的显示装置中，如图24所示，的显示装置还可以包括：位于副显示面板区域B背离中框102一侧的外壳105上的摄像头107。并且，为了不影响观看副显示面板区域B的显示画面，摄像头107在外壳105 的正投影与副显示面板区域B在外壳105的正投影无交叠。并且，由于摄像头107位于显示装置的副显示面板区域B所在侧，其采集的自拍等图像可设置在副显示面板区域B上显示，因此，如图25所示，无需在显示装置的主显示面板区域A所在侧设置摄像头107，从而使得主显示面板区域A上真正实现了100％屏占比的全屏显示。
在本公开实施例提供的显示装置中，可将全屏显示的主显示面板区域A用于用户需要观看内容的显示，例如可设置wifi、蓝牙等快捷图标，以及时间、天气、日程等的提醒，以及观看电影等视频画面。副显示面板区域B可用于电子书阅读，还可用于进行微信、电话等社交消息的处理，从而在主显示面板区域A上正在显示电影、游戏等内容时，可以在副显示面板区域B上处理微信、电话等社交消息，从而不会打断主显示面板区域A上正在显示的电影、游戏等内容，极大提升了用户的沉浸体验。
此外，在本公开实施例提供的上述显示装置中，可以使主显示面板区域的刷新频率与副显示面板区域的刷新频率不同。例如可以通过时序控制器TCON的时钟信号来控制主显示面板区域的刷新频率与副显示面板区域的刷新频率不同。例如在使用主显示面板区域时，主显示面板区域的刷新频率为60Hz，副显示面板区域的刷新频率为10Hz，从而大大节省了功耗。
另外，在本公开实施例提供的显示装置中，如图25所示，若将全屏显示的主显示面板区域A的尺寸设定为5.8寸(18:9)，边a可以为143.9mm，边b可以为70.9mm，分辨率可以为2436*1125；副显示面板区域B设计可以为正方形，如图24所示，则其尺寸可以为3.9寸(9:9)，边b可以为70.9mm，分辨率可以为1125*1125。弯折区域C采用图6所示的半圆型结构，则弯折区域C对应的柔性显示面板的长度可以为4*π≈12.56mm，则柔性显示面板101的整体长度可以为143.9+70.9+4*π＝227.37mm，因此弯折前的柔性显示面板101的尺寸约为9.4寸(29:9)，分辨率为3849*1125。当然，上述仅为主显示面板区域A、副显示面板区域B和弯折区域C的一些设计方案，在具体实施时，可参考上述设计方法，并根据实际需要来进行设计，在此不做具体限定。
基于同一发明构思，本公开实施例提供了一种显示装置的制作方法，由于该制作方法解决问题的原理与上述显示装置解决问题的原理相似，因此，本公开实施例提供的该制作方法的实施可以参见本公开实施例提供的上述显示装置的实施，重复之处不再赘述。
如图26所示，本公开实施例提供的一种显示装置的制作方法，具体可以通过以下步骤实现：
S2601、提供柔性显示面板和中框；
S2602、将柔性显示面板绕中框进行弯折，使柔性显示面板形成分别位于中框两侧的主显示面板区域和副显示面板区域，以及连接主显示面板区域与副显示面板区域的弯折区域。其中主显示面板区域作为主显示面板，副显示面板区域作为副显示面板。
在具体实施时，形成的弯折区域可以包括半圆型结构和U型结构中之一。
需要说明的是，在本文中，诸如第一和第二之类的关系术语仅仅用来将一个实体或操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。
本公开实施例提供的显示装置及其制作方法，该显示装置包括中框和绕中框弯折的一体化的柔性显示面板。其中，柔性显示面板包括主显示面板所在的主显示面板区域，副显示面板所在的副显示面板区域，以及绕中框弯折以连接主显示面板区域和副显示面板区域的弯折区域。由于采用一块柔性显示面板即可实现双屏显示的功能，因此有效降低了成本与整机设计难度。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
