【具体实施方式】
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，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例中的术语“第一”、“第二”、“第三”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”、“第二”、“第三”的特征可以明示或者隐含地包括至少一个该特征。本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在柔性显示面板中，尤其是柔性LCD(Liquid Crystal Display)或OLED（Organic Light-Emitting Diode）显示面板中，其上下基板衬底材料为柔性玻璃、聚亚酰胺（polyimide，PI）基板、聚对苯二甲酸乙二醇酯（polyethylene terephthalate，PET）基板或聚二甲基硅氧烷（Polydimethylsiloxane，PDMS)基板等有机塑料薄膜的器件，因而能够实现单一方向或任意方向上的不同程度弯曲。
柔性显示面板能保证较好的成像质量的关键技术之一为挡墙结构，挡墙的结构通常设计成单向平行排列或双向井字形网络结构，用于对子像素区的液晶进行隔离，使得在柔性显示面板弯曲时，可以避免各子像素区之间液晶的乱流，以保证显示质量。
然而相对封闭的挡墙结构则会在成盒制程段影响配向膜溶液和液晶灌装的扩散均匀性，致使配向膜溶液和液晶无法均匀扩散，影响柔性显示面板显示质量。
参阅图1，本申请提供的柔性液晶显示面板一实施例的结构示意图。
该柔性液晶显示面板包括上基板10、与上基板10相对设置的下基板20及设置于上基板10与下基板20之间的液晶层30。其中，下基板20上设置有多个子像素区21，围绕子像素区21设置有挡墙40，挡墙40上设置有缺口41，使得多个子像素区21之间具有流动性。
可选地，挡墙40为黑色光阻间隙物(Black Photo Spacer，BPS)。挡墙40起到黑矩阵(Black Matrix，BM)及间隔物(Photo Spacer，PS)的双重作用。挡墙40由黑色感光树脂、多层不同颜色滤光层的堆叠或其它有机材料制成，例如红色滤光层材料、蓝色滤光层材料、绿色滤光层材料的堆叠，或其他适合的材料。液晶显示面板中，像素电极层与公共电极层重叠的区域称为驱动区域，没有像素电极的区域称为非驱动区域，挡墙40设置于非驱动区域处，以代替黑矩阵及间隔物。
可选地，挡墙40设置于上基板10。例如，上基板10为彩膜基板。上基板10包括衬底基板和依次设置于衬底基板上的滤光层、公共电极层，滤光层包括对应各子像素区21的红色滤光片、绿色滤光片、蓝色滤光片，各滤光片之间设置有挡墙40，挡墙40上设置有缺口41。本申请仅对挡墙40设置于上基板10的结构做简要介绍，还有其他多种挡墙40设置于上基板10的结构，本申请对此不作限制。
可选地，挡墙40设置于下基板20。例如，下基板20为阵列基板。上基板20包括衬底基板和依次设置于衬底基板上的TFT结构、保护层、像素电极层，在衬底基板上形成阵列分布的多个TFT结构，多个TFT结构包括多个薄膜晶体管以及电容电极线，电容电极线例如是水平设置的扫描线和竖直设置的数据线，扫描线与数据线将衬底基板分割出呈阵列排布的多个子像素区21，每个子像素区21对应设置有像素电极，于多个TFT结构上设置保护层，在于保护层上对应扫描线或/和数据线的区域设置挡墙40，于保护层上对应的子像素区域设置像素电极层。其中，挡墙40上设置有缺口41。或者，还于下基板20上设置滤光层，滤光层设置于TFT结构和像素电极层之间。本申请仅对挡墙40设置于下基板20的结构做简要介绍，还有其他多种挡墙40设置于下基板20的结构，本申请对此不作限制。
其中，衬底基板为柔性玻璃、聚亚酰胺基板、聚对苯二甲酸乙二醇酯基板或聚二甲基硅氧烷基板等柔性基板。
上基板10或下基板20上设置有挡墙40，在下基板20上涂布配向膜溶液，经预烤、固烤和配向后，再于下基板20上制作胶框，进行液晶灌装，之后上基板10与下基板20进行对盒工艺，再划屏切割以形成柔性液晶显示面板。
可选地，下基板20包括多条数据线22、多条扫描线23，多条数据线22和多条扫描线23交叉设置以形成多个子像素区21，挡墙40沿扫描线23或数据线22设置，挡墙40上设置有至少一个缺口41。即挡墙40不管设置于上基板10或下基板20上，其在柔性液晶显示面板中均对应于扫描线23或数据线22的位置设置。
可以理解地，挡墙40沿扫描线23或数据线22设置，其与该扫描线23或数据线22经过的子像素区21数目相同，即挡墙40贯穿其所在方向上的液晶层；挡墙40上设置有缺口41，应当理解为缺口41相对挡墙40而言是可以明显被辨认出，即间隔物支撑柱不应当被认定为挡墙40，相邻隔物支撑柱之间的空间也不应被识别为缺口41。
参阅图2，在一实施方式下，挡墙40仅沿数据线22设置，且各挡墙40上均设置有一个缺口，进而得以保证各子像素区21能够互联互通。例如，沿数据线22平行排列的多条挡墙40，其上设置的缺口41有如下规律，挡墙40上的缺口41面对一子像素区21，下一挡墙40上的缺口41面对该子像素区21的对角子像素区21设置；或者，多条挡墙40上的缺口41在一条直线上，即各缺口41位置连成线贯穿同一行的多个子像素区21。由于未在扫描线23对应位置上设置挡墙40，同一数据线22途径的多个子像素区21是连通的，又各挡墙40上均设置有一缺口41，在液晶面板的制程工艺中，如配向液涂敷和液晶灌装工艺，各子像素区的配向液和液晶可相互流动以使其均匀，以及在不显著恶化挡墙40防乱流的前提下，柔性液晶显示面板受压弯曲时，各子像素区21的液晶便于自行调整扩散，互相流通以使不同区域的液晶仍然保持均匀，例如弯曲区和非弯曲区的液晶分子，以保证较好的显示质量。
可选地，挡墙40还可仅沿扫描线23设置，以及平行排列的多条挡墙40上，每一挡墙40可设置多个缺口41，且缺口41位置任意，或者各挡墙40上设置的缺口41数目不等，位置不定，仅需保证各挡墙40上设置有至少一个缺口41，以保障各子像素区21之间具备流动性即可。
参阅图3，在另一实施方式下，挡墙40对途径的各子像素区21均设置有相应的缺口41。例如，仅沿数据线22平行排列的多条挡墙40，挡墙40对途径的各子像素区21均设置有相应的缺口41，且对应同一子像素区21的相邻挡墙40上的缺口41位置相同，进而多个缺口41呈阵列排布，以在不显著恶化挡墙40防乱流的前提下，使得各子像素区21的液晶更易相互流动，及柔性液晶显示面板在液晶滴灌或配向液涂敷时，使其在各子像素区21之间流动均匀，以保证各子像素区21配向液和液晶的均匀性，以及在柔性液晶显示面板受压弯曲时，更加快捷的调整各子像素区21的液晶，以保证柔性液晶显示面板良好的显示质量。
或者，参阅图4，仅沿数据线22平行排列的多条挡墙40，挡墙40对途径的各子像素区21均设置有相应的缺口40，且对应同一子像素区21的相邻挡墙40上的缺口41错位设置，进而相比于相邻挡墙40上的缺口41位置相同的方式，其减缓了相邻子像素区21液晶分子的流动性，增加了相邻子像素区21液晶分子流动的路程，有利于增加柔性液晶显示面板显示质量的稳定性。当然，以上两种缺口的设置方式还可应用于仅沿扫描线23平行排列的多条挡墙40上。
参阅图5，在另一实施方式下，沿数据线22设置有第一挡墙42，沿扫描线23设置有第二挡墙43，第一挡墙42和第二挡墙43中的一种对应各子像素区21均设置有缺口41，第一挡墙42和第二挡墙43中的另一种上设置有至少一个缺口41。例如，沿数据线22和扫描线23排列的双向井字形网络结构的第一挡墙42和第二挡墙43。其中，沿数据线22排列的第一挡墙42对应各子像素区21均设置有缺口41，沿扫描线23排列的每一第二挡墙43上仅设置一个缺口41，进而多个子像素区21内的配向液、液晶在沿扫描线23方向上相对而言具有更强的流动性，而多个子像素区21内的配向液、液晶在沿数据线22方向上能够流动。相对于沿扫描线23方向上流动的液晶分子，沿数据线22方向上流动的液晶分子受到的阻挡较多，进而相对前述柔性液晶显示面板的成像质量具有更好的稳定性。
参阅图6，在另一实施方式下，第一挡墙42和第二挡墙43上对应各子像素区21均设置有缺口41，以增强各子像素区21液晶的流动性。此时，可通过调整第一挡墙42和第二挡墙43上缺口41的大小，在保证各子像素区21液晶的流动性，同时还考虑柔性液晶显示面板在弯曲状态下的成像质量，即各子像素区21液晶的流动性在某种程度上还应受到限制。
可选地，第一挡墙42对应各子像素区21均设置有缺口41，第二挡墙43上设置有多个缺口41，例如三个、五个，无需对应各子像素区21均设置有缺口41，缺口41位置沿第二挡墙43均匀设置，或相邻第二挡墙43的缺口41位置交叉错位设置。
参阅图7，在另一实施方式下，第一挡墙42与第二挡墙43的交叉处设置有缺口41，以使一子像素区21可与相邻的八个子像素区21的液晶直接相互流动。在子像素区间21液晶易于充分流动的同时，仍有第一挡墙42与第二挡墙43对液晶或配向液的流动起缓冲作用。
结合参阅图8，在另一实施方式下，挡墙40包括主挡墙44和次挡墙45，主挡墙44与上基板10、下基板20均接触，次挡墙45与上基板10、下基板20中的一个接触。挡墙40设置于上基板10或下基板20上，即主挡墙44和次挡墙45均设置于上基板10或下基板20。
可选地，缺口41处设置有次挡墙45。挡墙40包括一体式的主挡墙44和次挡墙45，由于次挡墙45与上基板10或下基板20具有间隙，该间隙可作为缺口41以连通相邻的子像素区21。进而，部分液晶或配向液易于通过该间隙处向邻近的子像素区21流动，部分或配向液被次挡墙40阻挡不易向邻近的子像素区21流动，即保证了液晶或配向液扩散的均匀性，也利于柔性液晶显示面板的成像质量的稳定性。例如，将上述各实施方式中的缺口41均置换成次挡墙45，则相对于在挡墙45上制作缺口41，制作次挡墙45的耗费的工时将有效缩短。例如，挡墙40上的缺口41采用光罩工艺形成，次挡墙45与上基板10或下基板20间的间隙高度比缺口41高度低，进而采用光罩工艺耗费工时就较少。
参阅图9，可选地，挡墙40上同时设置次挡墙45和缺口41。挡墙40包括主挡墙44和次挡墙45，主挡墙44与次挡墙45为一体式，缺口41设置于主挡墙44上。此处，缺口41、主挡墙44、次挡墙45与前述实施例中的作用类似，不再赘述。
参阅图10，本申请提供的柔性液晶显示器一实施例的结构示意图。
该柔性液晶显示器50包括柔性液晶显示面板51。其中，柔性液晶显示面板51是如上述的柔性液晶显示面板，不再赘述。
区别于现有技术的情况，本申请公开了一种柔性液晶显示面板和柔性液晶显示器。该柔性液晶显示面板包括上基板、与上基板相对设置的下基板及设置于上基板与下基板之间的液晶层；下基板上设置有多个子像素区，围绕子像素区设置有挡墙，挡墙上设置有缺口以允许设于多个子像素区内的液晶在柔性液晶显示面板受压弯曲时相互流通。通过在柔性液晶显示面板中封闭式的挡墙结构上设置缺口，解决了在液晶滴灌或配向夜涂布时封闭式挡墙结构对液晶和配向液扩散的影响，避免了由于这些因素而导致显示面板上坏点的产生，提高了显示面板成盒的良率和有利于减少紫外光配向的时间，以及在不显著恶化挡墙防乱流的前提下，柔性液晶显示面板受压弯曲时，便于液晶分子自行调整扩散，以保证较好的显示质量。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
