 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“第一”和“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”和“第二”等的特征可以明示或者隐含地包括一个或者更多个所述特征，因此不能理解为对本申请的限制。此外，术语“上”、“下”、“内”、“外”、“一侧”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
请参阅图1，图1是本申请提供的柔性显示模组的第一结构示意图。如图1所示，柔性显示模组包括：衬底基板11；设置在衬底基板11上的第二胶层12；以及设置在第二胶层12上的显示面板13。其中，衬底基板11包括第一区域A’、第二区域B’以及设置在第一区域A’和第二区域B’之间的第三区域C’。第三区域C’上设置有第一凹槽111。第一凹槽111内填充有第一胶层21。第二胶层12覆盖第一胶层21。显示面板13包括第一显示区域A、第二显示区域B以及设置在第一显示区域A和第二显示区域B之间的弯折区域C。第一显示区域A与第一区域A’对应设置。第二显示区域B与第二区域B’对应设置。弯折区域C与第三区域C’对应设置。
其中，第一胶层21的材料与第二胶层12的材料可以是光学胶或者其它粘贴性良好并具有透光性的粘性材料。在一些实施例中，第一胶层21的材料与第二胶层12的材料相同，使得第一胶层21与第二胶层12更好的融合，当柔性显示模组弯折时，第一胶层21和第二胶层12能够提供更多的形变量，减小弯折应力，从而提高柔性显示模组的耐弯折性。
其中，第一凹槽111的剖面结构可以是矩形、梯形、三角形或者半圆形等形状，本申请对此不作具体限定。
其中，在本申请一实施例中，第一胶层21完全填充第一凹槽111。此时，若第一胶层21的材料与第二胶层12的材料相同，第一胶层21可以和第二胶层12完全融合，提供更多的形变量，从而提高柔性显示模组的耐弯折性。在本申请另一实施例中，第一胶层21的厚度小于第一凹槽111的深度。此时，当柔性显示模组弯折时，第二胶层12发生弹性形变，可流入第一凹槽111内，以避免第二胶层12断裂。
其中，弯折区域C可用于显示画面，也可不显示画面，具体可根据客户对柔性显示模组的规格要求进行设置，本申请对此不作限定。
其中，在本申请实施例中，柔性显示模组还包括依次设置于显示面板13上的偏光片14、粘贴层15以及玻璃盖板16。需要说明的是，本申请实施例提供的柔性显示模组的膜层结构并不限于此，不能理解为对本申请的限定。
请参阅图2，图2是本申请提供的柔性显示模组弯折时的结构示意图。如图2所示，本申请提供的柔性显示模组通过在衬底基板11对应弯折区域C的第三区域C’上设置第一凹槽111，并在第一凹槽111内填充第一胶层21，通过第一胶层21和第二胶层12提供更多的形变量，减小弯折应力，从而提高柔性显示模组的耐弯折性。
请参阅图3，图3是本申请提供的柔性显示模组的第二结构示意图。如图3所示，与图1所示的柔性显示模组的不同之处在于，在本申请实施例提供的柔性显示模组中，第一凹槽111的数量为多个，多个第一凹槽111间隔设置于第三区域C’内。多个第一凹槽111的设置可以提高第一胶层21与衬底基板11之间的粘贴面积，从而提高衬底基板11与显示面板13之间的结合强度，避免衬底基板11脱落。
需要说明的是，在一些实施例中，多个第一凹槽111可连续设置于第三区域C’内，在提高衬底基板11与显示面板13之间的结合强度的同时，增加第一凹槽111的整体容胶量。
请参阅图4，图4是本申请提供的柔性显示模组的第三结构示意图。如图4所示，与图1所示的柔性显示模组的不同之处在于，在本申请实施例提供的柔性显示模组中，第一区域A’靠近第三区域C’的一侧以及第二区域B’靠近第三区域C’的一侧均设置有第二凹槽112。第二凹槽112内填充有第三胶层22。
可以理解的是，当柔性显示模组弯折时，位于第一区域A’靠近第三区域C’的一侧以及第二区域B’靠近第三区域C’的一侧的衬底基板11也会受到相应的应力。因此，在第一区域A’靠近第三区域C’的一侧以及第二区域B’靠近第三区域C’的一侧均设置第二凹槽112，并在第二凹槽112内填充第三胶层22，可以进一步减小弯折应力，避免衬底基板11脱落。
其中，第三胶层22的材料可以是光学胶或者其它粘贴性良好并具有透光性的粘性材料。
其中，第二凹槽112的数量可以为一个或者多个。第二凹槽112的剖面结构可以是矩形、梯形、三角形或半圆形等形状。
在本申请一实施例中，第一凹槽111和第二凹槽112相互连通。在本申请另一实施例中，第一凹槽111和第二凹槽112间隔设置。
进一步的，第一凹槽111的深度大于第二凹槽112的深度。由于衬底基板11位于第三区域C’的部分受到的应力大于衬底基板11位于第一区域A’以及第二区域B’的部分受到的应力，因此设置第一凹槽111的深度大于第二凹槽112的深度，在增加第一胶层21和第三胶层22的同时，可以保证衬底基板11的刚性，避免柔性显示模组弯折后产生褶皱。
请参阅图5，图5是本申请提供的柔性显示模组的第四结构示意图。如图5所示，与图1所示的柔性显示模组的不同之处在于，本申请实施例提供的柔性显示模组还包括设置于显示面板13与第二胶层12之间的支撑板17。
其中，支撑板17通过第四胶层18与显示面板13粘合。支撑板17可由聚酰亚胺等材料制成，以起到支撑显示面板13的作用。支撑板17的刚性弱于衬底基板11的刚性。
进一步的，请参阅图6，图6是本申请提供的柔性显示模组的第五结构示意图。如图6所示，与图5中的柔性显示模组的不同之处在于，在本申请实施例提供的柔性显示模组中，支撑板17靠近衬底基板11的一侧设置有第三凹槽171。第三凹槽171与第一凹槽111对应设置。第二胶层12至少部分延伸至第三凹槽171内。
在本申请一实施例中，第三凹槽171可以贯穿支撑板17。此时，第二胶层12以及第四胶层18均至少部分延伸至第三凹槽171，进而提高衬底基板11与支撑板17以及显示面板13之间的结合强度。
在本申请一实施例中，请参阅图7，图7是本申请提供的柔性显示模组的第六结构示意图。如图7所示，与图6所示的柔性显示模组的不同之处在于，在本申请实施例提供的柔性显示模组中，第三凹槽171内填充有第五胶层23。第五胶层23完全填充第三凹槽171，使得第一胶层21、第二胶层12以及第五胶层23融合，能够提供更多的形变量，减小弯折应力，提高柔性显示模组的耐弯折性。
请参阅图8，图8是本申请提供的柔性显示模组的制作方法。如图8所示，本申请提供的柔性显示模组的制作方法包括以下步骤：
101、提供一衬底基板，所述衬底基板包括第一区域、第二区域以及位于所述第一区域和所述第二区域之间的第三区域；
102、在所述第三区域上形成第一凹槽；
103、在所述第一凹槽内形成第一胶层；
104、在所述衬底基板上形成第二胶层，所述第二胶层覆盖所述第一胶层；
105、在所述第二胶层上形成显示面板，所述显示面板包括第一显示区域、第二显示区域以及设置在所述第一显示区域和所述第二显示区域之间的弯折区域，所述第一显示区域与所述第一区域对应设置，所述第二显示区域与所述第二区域对应设置，所述弯折区域与所述第三区域对应设置。
本申请提供一种柔性显示模组的制作方法，通过在衬底基板对应弯折区的第三区域上形成第一凹槽，并在第一凹槽内填充第一胶层，第一胶层和第二胶层相互作用，能够提供更多的形变量，避免第一胶层21和第一胶层12发生断裂，从而提高柔性显示模组的耐弯折性。
现结合具体实施例对本申请的制作方法进行描述。
请参阅图1所示的柔性显示模组，本申请提供的柔性显示模组的制作方法的包括以下步骤：
101、提供一衬底基板，所述衬底基板包括第一区域、第二区域以及位于所述第一区域和所述第二区域之间的第三区域；
具体的，衬底基板11的材料为不锈钢材料，具有较强的刚性。当柔性显示模组进行弯折时，衬底基板11具有支撑和减缓起皱的作用。
102、在所述第三区域上形成第一凹槽；
具体的，通过激光刻蚀等工艺在第三区域C’上形成第一凹槽111。其中，第一凹槽111的数量可以是一个也可以是多个。第一凹槽111的剖面结构可以是矩形、梯形、三角形或半圆形等形状，本申请对此不作具体限定。
103、在所述第一凹槽内形成第一胶层；
具体的，可以采用涂布工艺或者片材贴合工艺在第一凹槽111内形成第一胶层21。涂布工艺是直接将胶层材料涂布在第一凹槽111内，以形成第一胶层21。片材贴合工艺直接将胶层材料形成的片材贴合在第一凹槽111内，以形成第一胶层21。
其中，在本申请一实施例中，第一胶层21完全填充第一凹槽111；在本申请另一实施例中，第一胶层21的厚度小于第一凹槽111的深度。
其中，第一胶层21的材料可以是光学胶或者其它粘贴性良好并具有透光性的粘性材料。
104、在所述衬底基板上形成第二胶层，所述第二胶层覆盖所述第一胶层；
具体的，在衬底基板11上涂布一层胶层材料，以形成第二胶层12。第二胶层12的材料可以是光学胶或者其它粘贴性良好并具有透光性的粘性材料。第二胶层12覆盖第一胶层21。当第一胶层21完全填充第一凹槽111时，第二胶层12可以与第一胶层21完全融合，提高第二胶层21的耐弯折性。
在本申请实施中，首先在第一凹槽内形成第一胶层21，然后在衬底基板11上形成第二胶层12，能够提高柔性显示模组的品质。可以理解的是，由于第一凹槽111的存在，如果采用一次涂布工艺同时形成第一胶层21和第二胶层12，会造成第二胶层12的厚度不均匀，影响衬底基板11与显示面板13之间的贴合，进而影响柔性显示模组的品质。
105、在所述第二胶层上形成显示面板，所述显示面板包括第一显示区域、第二显示区域以及设置在所述第一显示区域和所述第二显示区域之间的弯折区域，所述第一显示区域与所述第一区域对应设置，所述第二显示区域与所述第二区域对应设置，所述弯折区域与所述第三区域对应设置。
具体的，将显示面板13贴合到涂布有第二胶层12的衬底基板11上，使得第一显示区域A与第一区域A’对应设置，第二显示区域B与第二区域B’对应设置，弯折区域C与第三区域C’对应设置。
在本申请实施例中，还可依次在显示面板13上形成偏光片14、黏贴层15以及玻璃盖板16，本申请对此不作具体限制。
在本申请一实施例中，请参阅图5所示的柔性显示模组，本申请提供的柔性显示模组的制作方法包括以下步骤：

其中，关于步骤101、步骤104以及步骤105请参阅上述内容，步骤102和步骤103包括：在第三区域C’上形成第一凹槽111以及在第一区域A’靠近第三区域C’的一侧以及第二区域B’靠近第三区域C’的一侧形成第二凹槽112；在第一凹槽111内形成第一胶层21，在第二凹槽112内形成第三胶层22。
其中，可采用同一工艺制程形成第一凹槽111和第二凹槽112。
其中，在本申请一实施例中，第一凹槽111和第二凹槽112相互连通。在本申请另一实施例中，第一凹槽111和第二凹槽间隔设置。
进一步的，当第一凹槽111和第二凹槽112相互连通时，若第二凹槽112的深度等于第一凹槽111的深度，可采用同一工艺制程形成第一胶层21和第三胶层22；若第二凹槽112的深度小于第一凹槽111的深度，可采用相同的工艺制程分别形成第一胶层21和第二胶层22。
本申请实施例采用同一工艺制程在衬底基板11上形成第一凹槽111和第二凹槽112简化了生产工艺，同时通过增加第三胶层22，进一步提高了柔性显示模组的耐弯折性。
