 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，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。

 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，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，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发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
本发明针对现有的柔性显示装置，由于显示模组中的膜层材料主要为高分子薄膜材料，在弯折次数过多或者弯折曲率较小的情况下，易产生材料的应力松弛和弯折疲劳，导致显示装置在展开后，表面会发生翘曲，进而影响产品的外观和平整度的技术问题，本实施例能够解决该缺陷。
如图1所示，本发明实施例提供一种柔性显示装置100，包括显示模组10、均热板20、集热部件30、以及导热管40。
如图2所示，所述显示模组10上定义有弯折区域101，所述弯折区域101用以弯折，所述弯折区域101内定义有一条弯折线102，所述显示模组10沿着所述弯折线102进行弯折。
所述均热板20和所述集热部件30均设置于所述显示模组10的远离出光面的一侧，避免影响出光面的光线。所述均热板20与所述弯折区域101对应设置，当所述显示模组10处于展开状态时，所述均热板20向所述显示模组10的位于所述弯折区域101的部分传递热量。由于动态可弯折的柔性显示装置需要能够弯折多次，但是薄膜材料在弯折多次后易发生材料应力松弛和弯折疲劳，导致弯折区域101的显示模组10表面发生翘曲，因此，将所述均热板20与所述弯折区域101对应设置，利用均热板20上的热量有效作用在摊平后的翘曲部位，通过加快分子运动和分子重排，改善所述显示模组10表面发生的翘曲问题。
具体地，所述均热板20可贴附于所述显示模组10的背面（即远离所述显示模组的出光面一侧的表面）设置，使得热量最大程度地快速传递到所述显示模组10的表面。
所述均热板20可采用石墨或者铜箔作为均热材料，也可选自其他散热性良好的材料作为均热材料。
所述导热管40设置于所述均热板20和所述集热部件30之间，且连接所述均热板20和所述集热部件30，所述集热部件30将收集到的热量通过所述导热管40传递至所述均热板20，所述均热板20再将热量传递至所述显示模组10的弯折区域101，使得弯折区域101温度升高，将热量有效作用在弯折部位，并配合其他机构的拉伸作用，使得产品恢复平整。
为了使得所述均热板20上的热量较好地作用在翘曲部位，将所述均热板20的中心线设置于与所述弯折区域101上的弯折线102在所述显示模组10的厚度方向上重合；另外，使所述均热板在所述显示模组上的正投影位于所述弯折区域101内，也可将所述均热板20的形状尺寸设置于与所述的显示模组10的位于所述弯折区域101的部分相同。
所述导热管40设置于所述显示模组10的远离出光面的一侧，避免影响显示，具体可贴附于所述显示模组10的背面设置。
所述导热管40可为铜管或者碳纤维管等，利用管内部微液体循环导热，也可在所述导热管40的表面包覆一层保温层，避免热量在传导的过程中散失。
所述集热部件30收集的热量可来自于所述柔性显示装置100的内部元件在工作时的产热，例如在显示工作过程中，所述显示模组10内的驱动芯片、电池以及主板等部件会产热，集中收集这些产热，在产品摊平后作用在有翘曲的部位。设置所述集热部件30的好处在于，不用另外提供热量的同时，也能起到对所述柔性显示装置100的内部元件起到散热的作用，避免内部元件由于长时间运转产生高温负荷。
所述显示模组10为柔性OLED（Organic Light-Emitting Diode，发光二极管）显示模组，包括薄膜晶体管阵列基板、OLED发光器件、驱动芯片以及主板等。
为了更好实施本发明实施例中的柔性显示装置，在柔性显示装置的基础上，本发明实施例还提供一种提高上述柔性显示装置的稳定性的方法，如图3所示，具体包括以下步骤：
步骤S10，提供显示模组10，并在其上定义出弯折区域101和弯折线102，所述显示模组10可沿所述弯折线102进行弯折；
步骤S20，在所述显示模组10的远离出光面的一侧制备均热板20、集热部件30以及导热管40，其中，所述导热管40连接所述集热部件30和所述均热板20，且所述均热板20制备在与所述弯折区域101对应的区域内；
步骤S30，在所述显示模组10工作时，利用所述集热部件30收集所述显示模组10的内部元件产生的热量；
步骤S40，将弯折的所述显示模组10展开后，所述集热部件30将收集到的热量通过导热管40传递给所述均热板20，所述均热板20将所述热量传递到所述显示模组10上，对所述显示模组10的位于所述弯折区域101的部分进行加热，使得所述显示模组10的弯折区域101恢复平整。
所述集热部件30可收集所述显示模组10中的驱动芯片、电池以及主板等发热元件产生的热量。
所述均热板20对所述显示模组10的位于所述弯折区域101的部分的加热温度不高于50度，以避免对所述显示模组10的内部器件造成损伤，因此应设置一个温度传感器用以监测所述弯折区域101内的弯折部位的温度。
有益效果：通过在所述显示模组的背面设置均热板和集热配件，将显示装置进行工作过程中的产热收集起来，在柔性显示装置摊平的时候，将收集的热量作用在有翘曲的弯折部位，加快分子运动，使得翘曲弯折部位恢复平整，进而改善产品外观和提高产品的稳定性。
综上所述，虽然本发明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发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
