较佳地，在本公开实施例提供的上述显示面板中，该聚偏氟乙烯利用在二甲基甲酰胺和丙酮的体积比为6∶4的混合溶液中通过电纺技术制得，使得所得的聚偏氟乙烯的质量浓度为12％。该聚偏氟乙烯的透气性好、防水性能佳。
在具体实施时，本公开实施例提供的上述显示面板可以是液晶显示面板，当然也可以实施有机电致发光显示面板，在此不做限定。
在具体实施时，当本公开实施例提供的上述显示面板为有机电致发光显示面板时，如图3a和图3b所示，在像素单元11中一般设置有阳极层111、发光层112和阴极层113，而像素单元11周边一般至少设置有栅线、数据线等信号线以及TFT等电子器件。
因此为了避免通孔影响信号线和TFT从而影响显示，较佳地，在本公开实施例提供的上述显示面板中，如图3a和图3b所示，通孔12设置在像素单元11所在区域的中间区域，其中图3b为图3a沿A-A’方向的剖面示意图。
较佳地，在本公开实施例提供的上述显示面板中，如图4所示，通孔12的内壁还设置有封装膜层14，以避免水汽进入显示面板本体1内部，从而影响显示面板寿命。
在具体实施时，在本公开实施例提供的上述显示面板中，通孔所在的面积可以依据显示和透气功能的需求，根据实际情况决定。较佳地，为了不严重影响到显示效果，通孔在基板的正投影面积小于像素 单元在基板的正投影面积的1/5。

较佳地，在本公开实施例提供的上述显示面板中，柔性基板的材料为聚酰亚胺。
图5为本公开实施例提供的显示面板的制备的流程图。
在步骤51处，首先制备形成显示面板本体。在具体实施时，本公开实施例制备的显示面板本体可以是液晶显示面板的，当然也可以是有机电致发光显示面板的，在此不做限定。以有机电致发光显示面板为例而非限制，通过光刻方法在柔性基板上依次制备出薄膜晶体管、绝缘层、阳极层、发光层、阴极层和保护层，从而形成显示面板本体。
其后在步骤52处，形成贯穿该显示面板本体的通孔。作为示例而非限制，通过干刻、湿刻、激光和贯穿等工艺，形成贯穿显示面板本体的通孔。在具体实施时，在本公开实施例提供的显示面板的制备方法中，通孔所在的面积可以依据显示和透气功能的需求，根据实际情况决定。较佳地，为了不严重影响到显示效果，使得通孔在基板的正投影面积小于像素单元在基板的正投影面积的1/5。在具体实施时，在本公开实施例提供的显示面板的制备方法中，一个像素单元所在的区域内可以设置一个通孔，也可以设置多个通孔，在此不作限定。较佳地，当一个像素单元所在的区域内设置的通孔的数量为多个时，将多个通孔在像素单元所在的区域内均匀设置。在具体实施时，在本公开实施例提供的显示面板的制备方法中，在显示区域内设置多个通孔，且多个通孔在显示区域内均匀设置。这样可以使显示面板具有更好的 透气性。显示面板本体具有显示区域和包围显示区域的周边区域，可以在显示区域内形成通孔，也可以在周边区域形成通孔，在此不做限定。在本公开的实施方式中，显示区域包括基板和位于该基板上的像素单元，较佳地，贯穿基板和像素单元、在像素单元所在的区域内形成通孔。
本公开实施例提供的上述上述显示面板在制备时可以是在基板上形成像素单元后，再形成贯穿基板和像素单元的通孔，最后再在通孔中填充疏水透气材料。当然在实施时，也可以是形成一层或多层膜层(例如绝缘层、阳极层、发光层等)后，在这些膜层中与通孔对应位置处形成通孔，当最后一层膜层中的通孔形成后，整个通孔完成，然后再在通孔中填充疏水透气材料。
可选地，在步骤53处，在该通孔的内壁设置封装膜层。以避免水汽进入显示面板本体的内部，从而影响显示面板寿命。
在步骤54处，获得疏水透气材料，以便填充到各通孔中。可选地，该材料也可通过制备来取得，也可通过其它方式取得，在此不做限定。较佳地，在本公开实施例提供的显示面板的制备方法中，采用的疏水透气材料为具有多个微孔的聚合物，这样只有空气或者水蒸汽才能透过通孔而液体则不能渗透。较佳地，在本公开实施例提供的显示面板的制备方法中，微孔的孔径为0.1微米-50微米。在具体实施时，在本公开实施例提供的显示面板的制备方法中，所采用的聚合物可以是天然聚合物，可也是合成聚合物，在此不作限定。较佳地，在本公开实施例提供的上述显示面板中，所采用的聚合物为聚偏氟乙烯、聚氨酯或聚四氟乙烯等。在具体实施时，当疏水透气材料为聚偏氟乙烯时，可以在二甲基甲酰胺/丙酮混合溶液中通过电纺技术制得聚偏氟乙烯。进一步地，当二甲基甲酰胺/丙酮混合溶液体积比为6∶4时，可以制得质量浓度为12％的聚偏氟乙烯，且该聚偏氟乙烯的透气性好、防水性能佳。
在步骤55处，将疏水透气材料填充到各通孔中，并进行固化。作为示例而非限制，通过涂覆工艺将疏水透气材料填充到各通孔中。基于同一构思，本公开实施例还提供了一种可穿戴设备，包括显示组件，该显示组件采用本公开实施例提供的上述显示面板。由于该可穿戴设备解决问题的原理与前述一种显示面板相似，因此该可穿戴设备的实 施可以参见前述显示面板的实施，重复之处不再赘述。
本公开实施例提供的一种显示面板、其制备方法及可穿戴设备，由于显示面板本体具有通孔，因此可以使该显示面板具有透气性，从而当该显示面板应用于可穿戴设备时，能提高可穿戴设备的穿戴舒适性。并且由于通孔内填充有疏水透气材料，因此可以保证在提升透气性的基础上，不仅防止外界的水分、油污等物质进入设备内部，而且可以避免由于设置通孔的孔洞带来的对产品的外观的影响。
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。
