电子纸显示(Electrophoretic Display)主要包括薄膜电晶体基板(TFT)、电子墨水薄膜(EINK Film)和保护膜。如图1所示的电子纸显示装置，电子墨水薄膜1位于薄膜电晶体基板2上，且电子墨水薄膜1上覆盖保护膜3，以保护电子墨水薄膜1。在相关技术中，为了实现电子墨水薄膜1的密封，通常在保护膜3与薄膜电晶体基板2之间采用密封胶4密封。为了方便薄膜电晶体基板2与保护膜3之间封胶4的涂布，以保证对电子墨水薄膜1的密封性，通常保护膜3的尺寸小于薄膜电晶体基板2的尺寸。然而，在该设置方式中，位于下层的薄膜电晶体基板2通常采用玻璃材料制成，因此在四角位置处容易出现因震动跌落造成破裂不良，从而导致线路受损的问题。
为了解决上述技术问题，本公开提供一种显示模组以及包含该显示模组的显示装置，其可以解决当由硬质脆性材料制成的基板在四角位置处容易出现因震动跌落造成破裂，进而导致线路受损的问题。

在本公开的可选实施例中，所述基板可以由玻璃材料制成，或者由其他脆性较大、因碰撞容易破碎的材料制成。
在本公开实施例所述的显示模组中，所述显示层设置于所述基板的第一表面上，并且当第一表面朝上放置时，该基板位于显示层的下方。可选地，所述基板为位于显示层下方且全部由硬质脆性材料制成的基板。进一步可选地，所述基板可以包括一层材料的基板，也可以包括至少两层材料的基板。例如，当显示层的下方包括多层的硬质脆性材料制成的基板时，本公开实施例中所提及的“基板”可以为该多层硬质脆性材料制成的基板的组合体。
在本公开的实施例中，所述显示层为显示模组中用于实现显示功能的全部显示单元。例如，当本公开实施例所述显示模组为电子纸显示器的显示模组时，本公开的基板为用于设置薄膜晶体管阵列的基板，并且所述显示层包括电子墨水膜层。当然，本公开实施例所述的显示模组不限于仅能够为电子纸显示器的显示模组。
由于在电子纸显示器的显示模组中，硬质脆性材料制成的薄膜电晶体基板的边缘突出于电子墨水薄膜层和保护膜，所以薄膜电晶体基板的四角位置容易因震动跌落造成破裂。下文将以电子纸显示器的显示模组为例，对本公开实施例所述显示模组的具体结构进行详细说明。
在本公开的可选实施例中，在基板的相邻两个侧面的连接位置处，保护结构包括连接面，并且所述连接面在所述连接位置处连接所述两个相邻的侧面。通过使所述基板的相邻两个侧面利用连接面相连接的方式代替相关技术中在两个相邻的侧面的连接处形成尖角的结构，避免了由于尖角容易破裂造成的损坏。
参阅图2为本公开实施例所述显示模组的一种实施方式的结构示意图。在该实施方式中，所述显示模组包括：
基板100和设置于基板100的第一表面110上的显示层200；
保护结构300，设置于基板100的相邻两个侧面120的连接位置处；
其中，两个侧面120分别与第一表面110连接。
在该实施方式中，保护结构300包括连接面130，通过连接面130代替现有技术在两个侧面的连接处形成尖角的结构，避免由于尖角容易造成破裂、 进而导致线路受损的问题。
在本公开的可选实施例中，如图3示出了基板100的平面结构示意图。连接面130位于基板100的相邻两个侧面120的连接位置处，也即直接将基板100的相邻两个侧面120的连接位置制作为连接面，以形成保护结构300。这可以避免在相邻的两个侧面120的连接位置处形成尖角。
在本公开的可选实施例中，连接面130为平面或者圆弧曲面。
除可以使基板100的相邻两个侧面120的连接位置设置为连接面之外，本公开实施例所述的显示模组也可以通过在基板100的相邻两个侧面120的连接位置处设置覆盖体，具体如图4所示的。通过覆盖体的方式，使基板100的相邻两个侧面120之间通过覆盖体而连接。
基于上述实施方式，如图7所示的，所述保护结构可以包括覆盖基板100的相邻两个侧面120的连接位置的第一覆盖体900，并且连接面910位于第一覆盖体900上。也即，通过设置第一覆盖体900，用于覆盖基板100的两个相邻的侧面120的连接位置的尖角，并在第一覆盖体900上设置形成为平面或圆弧曲面的连接面910，使连接面910位于基板的相邻两个侧面之间。该设置代替了相关技术中在两个相邻的侧面的连接处形成尖角的结构，避免由于尖角容易破裂、进而造成损坏的问题。
在本公开的可选实施例中，虽然附图中未显示出通过第一覆盖体形成连接面并且覆盖基板的两个相邻的侧面之间的尖角的其它具体结构，但是根据以上的描述，本领域技术人员可以了解在基板上设置上述结构的第一覆盖体的具体方式，在此不再详细说明。
在本公开的可选实施例所述的显示模组中，如图2和图3所示的，在基板100的每两个相邻的侧面120之间的连接位置处均设置有保护结构300，用于有效保护基板100的每一边角位置。也即在每两个相邻的侧面120之间的连接位置均设置有连接面130。
在本公开的另一可选的实施例中，所述保护结构包括从基板的第一表面的上方延伸至基板的两个相邻的侧面的连接位置的第二覆盖体。
在上述实施例中，通过第二覆盖体覆盖基板的两个相邻的侧面的连接位置，保护该连接位置，以减小由于震动跌落造成破裂、进而造成损坏的风险。
在本公开的可选实施例中，第二覆盖体由柔性材料制成。可选地，第二覆盖体在第一表面上方，整个地覆盖所述基板的两个相邻的侧面的连接位置，也即延伸的范围可以超出两个相邻的侧面的连接位置。
可选地，第二覆盖体也可以部分地覆盖在第一表面并从第一表面上方延伸，并包覆相邻两个侧面的连接位置，以保护该连接位置。
具体地，如图4所示，所述显示模组包括：
基板100和设置于基板100的第一表面110上的显示层200；
其中，在基板100的相邻两个侧面120的连接位置处设置有保护结构300，两个侧面120分别与第一表面110连接。
在该实施方式中，保护结构300可选地包括从第一表面110的上方延伸至基板100的相邻两个侧面120的连接位置的第二覆盖体1000。
具体地，如图4和图5所示的，所述显示模组还包括设置于显示层200上的保护层400，其用于隔离显示层200与外界空气，以达到保护显示层200的效果。可选地，该保护层400包括覆盖显示层200的主体部分410和与主体部分410连接、朝连接位置延伸的延伸部分420。可选地，主体部分410在第一表面110上的正投影位于第一表面110的内部，延伸部分420形成为上述的第二覆盖体1000。
在本公开的实施例中，显示层200在第一表面110上的正投影位于第一表面的110的内部。可选地，主体部分410在第一表面110上的正投影覆盖显示层200在第一表面110上的正投影，以使得通过保护层400的主体部分410能够对显示层200进行保护。
在本公开的可选实施例中，保护层400在主体部分410的四个边角位置分别设置有延伸部分420。可选地，每个该延伸部分420分别朝基板100的相邻两个侧面120的其中一连接位置处延伸，整个地覆盖基板100的相邻两个侧面120的连接位置，或者包覆相邻两个侧面120的连接位置。
根据本公开的再一实施例，如图6所示的，所述显示模组包括：
基板100和设置于基板100的第一表面110上的显示层200；其中，在基板100的相邻两个侧面120的连接位置处设置有保护结构300，两个侧面120分别与第一表面110连接。
在该实施方式中，保护结构300不仅包括位于基板100的相邻两个侧面120的连接位置处的连接面130，还包括从第一表面110的上方延伸至基板100的相邻两个侧面120的连接位置的第二覆盖体1000。
具体地，使位于显示层200上方的保护层400从主体部分410的四个边角位置分别设置延伸部分420，通过延伸部分420形成上述的第二覆盖体1000。
可选地，所述连接面130可以为平面，也可以为圆弧曲面。可选地，延伸部分420可以在第一表面110上整个地覆盖基板100的相邻两个侧面120的连接位置，也可以包覆相邻两个侧面120的连接位置。
通过采用上述的设置方式，将基板100的相邻两个侧面120的连接位置设置为连接面，同时通过保护层400上设置朝连接位置延伸的延伸部分420，能够有效地保护基板100的相邻两个侧面的连接位置，以避免因震动跌落造成破裂，从而导致线路受损的问题。
在本公开的实施例中，如图2至图6所示的，保护结构300位于显示层200在第一表面110上正投影之外的区域，也即保护结构300的设置位于显示层200之外的区域，不会影响显示层200的正常显示。
在本公开的可选实施例中，所述显示模组可以为电子纸显示的显示模组。例如，如图2、图4和图6所示的，基板100为用于设置薄膜晶体管阵列的基板，显示层200包括电子墨水膜层。
另外，如图2、图4和图6所示的，当显示模组为电子纸显示器的显示模组时，均包括上述的保护层400，还包括：柔性电路板(Flexible Printed Circuit Board，FPC)500和控制芯片600。FPC 500可选地独立于基板100设置，与基板100通过连接端子相连接。控制芯片600可选地设置于基板100上，且位于基板100的第一表面110的、设置有显示层200之外的区域。
可选地，控制芯片600的外围涂布有室温硫化型硅橡胶(room temperature vulcanized silicone rubber，RTV)610，用于保护控制芯片600。可选地，基板100与显示层200之间分布设置多个银胶连接点700，用于导通基板100上的薄膜晶体管阵列与显示层200上的电子墨水膜层，以能够通过薄膜晶体管阵列控制电子墨水膜层，实现显示功能。
可选地，在显示层200的四周边缘涂布有密封胶800，以达到密封基板 100与显示层200之间的空间，阻止水气进入显示层200的效果。
在本公开实施例所述的显示模组中，通过在显示模组下层的基板的相邻两个侧面的连接位置处设置保护结构，以防止相邻两个侧面的连接位置也即四角位置，容易因震动跌落造成破裂的问题。
需要说明的是，本公开实施例所述的显示模组不限于仅能够应用于电子纸显示的显示模组，采用上述实施方式设置保护结构的显示模组也可以为其他类型的显示模组，在此不再赘述。
另一方面，本公开还提供一种显示装置，所述显示装置包括上述的显示模组。根据以上的详细描述，本领域技术人员应该能够了解包括该显示模组的显示装置的具体结构，在此不再赘述。
