背景技术
随着显示技术的不断发展，为了满足不同的使用要求，各种具有不同特性的显示产品也随之应运而生。可折叠的柔性显示装置即是这样一种具有挠性的新型显示装置。当使用者要使用可折叠的柔性显示装置时，可展开整个可折叠的柔性显示装置的柔性显示屏，以将可折叠的柔性显示屏完全展开从而具有较大的显示画面。当使用者要携带时，可以折叠该可折叠的柔性显示屏，虽然会牺牲显示画面的尺寸，但由于折叠尺寸较小而能够有效提升携带的便利性。
当可折叠的柔性显示屏的分辨率很高时，一个驱动IC不能满足整个可折叠的柔性显示屏(Panel)的要求，需要采用两个驱动IC。然而，在折叠采用两个驱动IC驱动的可折叠的柔性显示屏时，折叠方向就会受到限制，只能沿与驱动IC垂直的方向进行折叠。如果显示屏采用整屏栅极驱动电路(GOA)一起驱动，那么在弯折部分显示时驱动难题较大，在全屏显示时，又无法实现无缝显示。

附图说明
为了更清楚地说明本公开实施例或相关技术中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
如图1至图4所示，本公开提供了一种可折叠的显示装置1，该可折叠 的显示装置1包括柔性显示面板10，第一面板支撑框架11以及第二面板支撑框架12。柔性显示面板10包括第一显示区域101、第二显示区域102及形成于第一显示区域101与第二显示区域102之间的弯折区域103。弯折区域103与第一显示区域101的第一边界1011以及第二显示区域102的第五边界1021连接。第一面板支撑框架11用于支撑第一显示区域101并且与第一显示区域101的显示背面直接接触，第二面板支撑框架12用于支撑第二显示区域102并且与第二显示区域102的显示背面直接接触。第一面板支撑框架11和第二面板支撑框架12可以彼此重叠或彼此展开，使得柔性显示面板10具有第一状态和第二状态。第一状态为柔性显示面板10完全折起的状态，第二状态为柔性显示面板10完全打开的状态。
在第一状态中，第一面板支撑框架11与第二面板支撑框架12彼此重叠并且直接接触，弯折区域103呈第一弯折状，第一显示区域101与第二显示区域102也彼此重叠且平行。在第二状态中，第一面板支撑框架11的与第一显示区域101接触的表面与第二面板支撑框架12的与第二显示区域102接触的表面处于同一平面内，并且在第一面板支撑框架11与第二面板支撑框架12之间形成容置空间；弯折区域103呈第二弯折状并容置于该容置空间内，第一显示区域101的第一边界1011与第二显示区域102的第五边界1021彼此抵靠对接而呈一平面显示屏结构。
在该实施例中，第一显示区域101的第一边界1011是第一显示区域101与弯折区域103相连接的边界，第二显示区域102的第五边界1021是第二显示区域102与弯折区域103相连接的边界，并且第一边界1011突出于第一面板支撑框架11之外，第五边界1021突出于第二面板支撑框架12之外，使得在第二状态中，当第一边界1011和第五边界1021彼此抵靠对接时，能够在第一面板支撑框架11和第二面板支撑框架12之间形成容置空间。
在折叠时，如图3和图4所示，将第一面板支撑框架11和第二面板支撑框架12彼此重叠并直接接触即可，使得第一显示区域101和第二显示区域102也彼此重叠(从垂直于第一显示区域101和第二显示区区域102的方向看)，此时柔性显示面板10的弯折区域103作为弯曲的部分，不会减小第一显示区域101和第二显示区域102的显示面积，且由于柔性显示面板10本身 具有一定厚度和张力，在折叠时，弯折区域103会自然形成一个弯曲半径，实现折叠。
在打开时，如图1和图2所示，第一面板支撑框架11和第二面板支撑框架12彼此分离，并且使第一显示区域101的第一边界1011和第二显示区域102的第五边界1021彼此抵靠对接而呈一平面显示屏结构，弯折区域103收容在由第一面板支撑框架11和第二面板支撑框架12形成的容置空间内。弯折区域103不进行显示，不会造成第一显示区域101和第二显示区域102之间的分区，从而实现无缝显示。
由此可见，本公开所提供的可折叠的显示装置可以解决相关技术中可折叠的显示装置的弯折部分在显示时驱动困难的问题，且能在全屏显示时实现无缝显示。
可选的，如图1所示，柔性显示面板10还包括用于驱动第一显示区域101的第一栅极驱动电路104以及用于驱动第二显示区域102的第二栅极驱动电路105。第一栅极驱动电路104可以设置在第一显示区域101的与第一边界1011相对的第二边界1012附近，第二栅极驱动电路105可以设置在第二显示区域102的与第五边界1021相对的第六边界1022附近。此外，第一栅极驱动电路104和第二栅极驱动电路105中的至少一个还可以设置在弯折区域103内。在本公开的实施例中，第一栅极驱动电路104和第二栅极驱动电路105可以是驱动IC(Integrated Circuit)和/或GOA(Gate-on-Array)。
在上述方案中，柔性显示面板10分为第一显示区域101和第二显示区域102两部分进行显示并且由不同的驱动电路驱动(即分屏驱动)。也就是说，第一显示区域101和第二显示区域102可以分别由独立的集成电路(IC)和阵列基板栅极驱动(Gate Driver Array(GOA))电路驱动。弯折区域103可以不用于显示，并且可以包括金属连接线和/或GOA，以避免在全屏显示时对柔性显示面板10的损坏。
在本公开所提供的实施例中，可选的，可折叠的显示装置1还包括第一锁定机构20，第一锁定机构20设置在第一面板支撑框架11和在第二面板支撑框架12上。第一锁定机构20用于在柔性显示面板10的第二状态下锁定第一面板支撑框架11和第二面板支撑框架12。
在本公开所提供的实施例中，可选的，如图2和图4所示，第一锁定机构20包括锁定槽201和锁定杆202。锁定槽201设置在第一面板支撑框架11的与弯折区域103相邻的第一侧面1101上；锁定杆202的第一端设置在第二面板支撑框架12的与弯折区域103相邻的第三侧面1201上，第二端能够插入或拔出锁定槽201。在柔性显示面板10的第一状态中，锁定杆202的第二端拔出锁定槽201之外；在柔性显示面板10的第二状态中，锁定杆202的第二端插入锁定槽201内，以锁定第一面板支撑框架11和第二面板支撑框架12。采用上述方案，第一锁定机构20采用锁定杆202与锁定槽201的配合结构，结构简单，操作方便。
可选的，如图2和图4所示，在柔性显示面板10的第一状态下，锁定杆202能够收容于由弯折区域103呈第一弯折状时与第一面板支撑框架11和第二面板支撑框架103共同形成的空间内；在柔性显示面板10的第二状态下，锁定杆202能够支撑于第一面板支撑框架11与第二面板支撑框架12之间。
上述方案中，当该可折叠的显示装置1需要进行全屏显示时，第一面板支撑框架11和第二面板支撑框架12相对于彼此打开，将第一显示区域101的第一边界1011和第二显示区域102的第五边界1021彼此抵靠对接，弯折区域103收容于由第一面板支撑框架11和第二面板支撑框架12形成的容置空间内，并将第二面板支撑框架12上的锁定杆202的第二端卡入到第一面板支撑框架11上的锁定槽201内，锁定杆202支撑在第一面板支撑框架12和第二面板支撑框架13之间，即实现全屏无缝显示。
当该可折叠的显示装置1需要折叠时，将锁定杆202的第二端拔出锁定槽201，并将第一面板支撑框架11和第二面板支撑框架12彼此重叠，柔性显示面板10的弯折区域103弯折，锁定杆202收容于弯折区域103所形成的空间内，即实现折叠双屏显示。
采用上述方案，锁定杆202一方面可以起到锁定的作用，另一方面还可以支撑在第一面板支撑框架11和第二面板支撑框架12之间，以限定出用于收容弯折区域103的容置空间。
需要说明的是，在实际应用中，第一锁定机构20的具体实现方式可以并不仅局限于此，还可以采用其他结构实现，在此不再一一列举。
此外，在本公开所提供的实施例中，可选的，锁定槽201为采用弹性可变形材料形成的可变形凹槽，锁定杆202的第二端设有一外径大于锁定槽201内径的由硬质材料制成的硬质球；或者，锁定槽201为采用硬质材料制成的不可变形凹槽，锁定杆202的第二端设有一外径大于锁定槽201内径的由弹性可变形材料制成的弹性球。采用上述方案，锁定杆202或锁定槽201中有一个为弹性可变性材料(例如弹性橡胶)，另一个为硬质材料，以使得锁定杆202能够卡入或拔出锁定槽201，两者配合结构简单，操作方便。
此外，在本公开所提供的实施例中，可选的，锁定杆202为一能够伸缩的伸缩杆结构。
采用上述方案，锁定杆202设计为伸缩杆结构，在该可折叠的显示装置1展开时，能够方便地插入到锁定槽201内，而在该可折叠的显示装置1折叠时，则可以伸缩，而方便地收入由柔性显示面板10的弯折区域103弯折时与第一面板支撑框架11和第二面板支撑框架12共同形成的空间内。
此外，在本公开所提供的实施例中，如图2和图4所示，第一面板支撑框架11固定于柔性显示面板10的第一显示区域101的显示背面，第二面板支撑框架12固定于柔性显示面板10的第二显示区域102的显示背面，并且第一显示区域101的第一边界1011突出于第一面板支撑框架11的距离以及第二显示区域102的第五边界1021突出于第二面板支撑框架12的距离可以根据需要进行调整。
在柔性显示面板10的第一状态中，第一显示区域101的显示背面与第二显示区域102的显示背面相面对，以使得柔性显示面板10进行双屏显示，且弯折区域103在柔性显示面板10的第一状态时的宽度能够使得第一面板支撑框架11和第二面板支撑框架12彼此重叠并贴合。采用上述方案，该可折叠的显示装置1在折叠时可以实现双屏显示，由于柔性显示面板10本身有一定厚度与张力，折叠时弯折区域103自然形成一个弯曲半径，且柔性显示面板10的弯折区域103的宽度由弯折区域103的弯曲半径决定。
可选地，柔性显示面板10还可以具有第三状态，第三状态为柔性显示面板10折起的状态，此时第一面板支撑框架11与第二面板支撑框架12彼此重叠，弯折区域103呈第三弯折状。然而，如图5所示，与第一状态不同，当 柔性显示面板10处于第三状态时，第一显示区域101的显示面与第二显示区域102的显示面彼此重叠并且直接接触，使得柔性显示面板10的显示面在内侧，不进行显示。
可选的，第一面板支撑框架11包括在柔性显示面板10的第二状态下与第二面板支撑框架12相背对的第二侧面1102，第二面板支撑框架12包括在柔性显示面板10的第二状态下与第一面板支撑框架11相背对的第四侧面1202。柔性显示面板10还包括第二锁定结构30，第二锁定结构30可以在柔性显示面板10的第一状态下锁定第一面板支撑框架11和第二面板支撑框架12，还可以在柔性显示面板10的第三状态下锁定第一面板支撑框架11和第二面板支撑框架12。所述第二锁定机构30的结构可以有多种方式，例如，第二锁定机构41可以包括设置在第二侧面1102和第四侧面1202上且能锁定或打开的锁扣结构。
以上所述仅是本公开的可选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本公开的保护范围。
