如图1至图5所示，本公开实施例提供了一种显示面板1，显示面板1包括：第一基板11、第二基板12、挡墙13、电泳流体和多组驱动电极组15。
第一基板11与第二基板12在竖直方向Y上相对设置，挡墙13支撑在第一基板11和第二基板12之间，并将第一基板11和第二基板12之间的空间分隔成多个在水平方向X上排布的封闭腔室14。
具体的，可以先在第一基板11或第二基板12上设置挡墙13，然后将第一基板11与第二基板12对置，挡墙13支撑在第一基板11与第二基板12之间，并与第一基板11及第二基板12围设形成多个封闭腔室14，各封闭腔室14之间通过挡墙13形成间隔。
要说明的是，上述中的“竖直方向Y”指的是与基板垂直的方向，水平方向X指的是与基板平行的方向。
第一基板11及第二基板12可以为玻璃基板，举例而言，当挡墙13在第一基板11或第二基板12上形成时，第一基板11或第二基板12可以为玻璃基板，以为挡墙13的形成提供支撑，但不限于此，也可采用聚酰亚胺(PI)、环氧树脂等材料制作第一基板11及第二基板12。
应当理解的是，本实施例中制作第一基板11及第二基板12的材料应当具有透光性，外界光线可透过第一基板11、第二基板12照射至电泳流体，从而可通过电泳流体对外界光线的吸收与反射，实现显示面板1的显示功能。
本公开实施例中，可采用具有一定硬度的材料制作挡墙13，以提升挡墙13对第一基板11及第二基板12的支撑性能，减小挡墙13倒塌而导致无法与第一基板11及第二基板12围设形成封闭腔室14的可能性。
进一步的，挡墙13可以设置为吸光挡墙13。例如，可以在挡墙13内注入吸光离子，或者直接利用黑色树脂等吸光材料制作挡墙13，从而挡墙13在对相邻两封闭腔室14进行间隔的同时，还可利用挡墙13进行吸光，以降低光线进入相邻两封闭腔室14之间的缝隙，并造成显示面板1漏光的可能性，从而可提升显示面板1的显示对比度。
此外，当相邻两封闭腔室14内为不同颜色的第二电泳粒子时，通过挡墙13可阻挡一封闭腔室14内的光线进入另一相邻封闭腔室14内，从而可减少相邻两封闭腔室14内的光线之间的相互干扰，保证各封闭腔室14对应的显示区域上的色彩的准确性，提升显示面板1的色彩还原度。
在每个封闭腔室14内形成电泳流体，其中，电泳流体包括第一电泳流体161和第二电泳流体162，第一电泳流体161和第二电泳流体162之间互不相容且带异种电荷。举例而言，第一电泳流体161可以带负电，第二电泳流体162则带正电；此外，第一电泳流体161也可以带正电，第二电泳流体162则带负电；第一电泳流体161和第二电泳流体162所带的电荷可根据实际情况而定。
本公开实施例中，第一电泳流体161用于吸收光线，第二电泳流体162和中间电极153中至少一者用于反射光线，从而可通过对第一电泳流体161和第二电泳流体162沿竖直方向Y分布的位置关系的调整，实现显示面板1显示情况的多样性。当第一电泳流体161位于第二电泳流体162靠近显示面板1中的显示面的一侧时，显示面板1可实现暗态显示，当第一电泳流体161位于第二电泳流体162远离显示面板1中的显示面的一侧时，显示面板1可实现亮态显示。此外，当仅第二基板12所在一侧为显示侧时，显示面板1可实现单面显示，当第二基板12所在一侧和所述第一基板11所在的一侧均为显示侧时，显示面板1可实现双面显示。
各封闭腔室14内，第一电泳流体161及第二电泳流体162的体积比可以为1:1，但不限于此，其他可以使第一电泳流体161(或第二电泳流体162)对第二电泳流体162(或第一电泳流体161)进行完全覆盖，以实现对外界光线的完全吸收(或完全反射)的比例，例如：在各封闭腔室14内，第一电泳流体161及第二电泳流体162的体积比为2:1、1:2、2:3、3:2、3:4、4:3、4:5、5:4等等，均包含在本公开的范围内。
本公开实施例中，显示面板1中还设置有多组驱动电极组15，驱动电极组15与封闭腔室14之间一一对应，其中，驱动电极组15包括沿竖直方向Y依次间隔设置的第一透光电极151、中间电极153和第二透光电极152，第一透光电极151形成在第一基板11上，第二透光电极152形成在第二基板12上，中间电极153位于封闭腔室14内，且中间电极153具有流通孔1531，流通孔1531能够供第一电泳流体161和第二电泳流体162通过。
流通孔1531为中间电极153上的镂空区域，如图1至4所示，各中间电极153上可以设置一个流通孔1531，但不限于此，如图5及图6所示，也可以在中间电极153上设置多个流通孔1531，具体可根据实际情况进行设定。各中间电极153上的流通孔1531的总面积至少占中间电极153整体面积(包含中间电极153的流通孔区域和非通孔区域)比例的1/5至2/5，保证电泳流体可通过流通孔1531实现在封闭腔室14内的快速流动，以提升显示面板1的刷新频率，继而可提升显示面板1的显示效果。
要说明的是，第一透光电极151及第二透光电极152具有透光性和导电性，向第一透光电极151及第二透光电极152分别施加不同电压，可在封闭腔室14内形成电场，在电场的控制下，可实现对第一电泳流体161及第二电泳流体162在封闭腔室14内位置排布的调整。当外界光线照射至显示面板1时，外界光线可透过第一透光电极151及第二透光电极152，并照射至电泳流体，从而可通过控制电泳流体在封闭腔室14内的位置关系，控制显示面板1对外界光线的吸收与反射，进而可实现显示面板1的显示功能。
在本公开的一种实施例中，中间电极153中朝向第一基板11的表面和朝向第二基板12的表面为反射面，此时，第二电泳流体162可以设置为透光电泳流体，当外界光线透过第二电泳流体162照射至中间电极153时，中间电极153可对外界光线进行反射，从而可通过对外界光线的反射，使显示面板1实现亮态显示。
要说明的是，反射面可以是在中间电极153朝向第一基板11的表面和朝向第二基板12的表面镀上的金属反射层，金属反射层可采用银、锌等在可见波段具有良好反射率的金属材料制成，但不限于此，其他在可见波段具有良好反射率的材料均可作为本公开中形成中间电极153的反射面的材料。
还要说明的是，上述中，中间电极153的流通孔区域是指，中间电极153中流通孔1531所处区域。中间电极153的非通孔区域是指，中间电极153中未设置镂空的区域，当中间电极153的外表面为反射面时，非通孔区域可用于对外界光线进行反射。
在本公开的另一种实施例中，第二电泳流体162设置为用于反射光线的电泳流体，当外界光线照射至第二电泳流体162时，第二电泳流体162可对外界光线进行反射，从而可利用外界光线的反射光线，使显示面板1实现亮态显示。
但不限于此，本公开实施例也可以在将中间电极153朝向第一基板11的表面和朝向第二基板12的表面为反射面的同时，将第二电泳流体162设置为用于反射光线的电泳流体。
要说明的是，电泳流体中通常设置有电泳粒子，电泳流体通过电泳粒子实现对外界光线的反射。当外界光线照射至第二电泳流体162时，部分外界光线照射至电泳粒子之间的缝隙，从而无法通过电泳粒子实现对外界光线的反射，此外，由于中间电极153上设置有流通孔1531，当外界光线照射至中间电极153的流通孔1531位置处时，外界光线也无法通过中间电极153实现反射。
本公开通过将中间电极153朝向第一基板11的表面和朝向第二基板12的表面设置为反射面，并将第二电泳流体162设置为用于反射光线的电泳流体，当外界光线照射至电泳粒子之间的缝隙时，可通过中间电极153的反射面对该部分外界光线进行反射；当外界光线在中间电极153上的正投影位于流通孔1531所在区域时，可通过第二电泳流体162对该部分外界光线进行反射，进而，本公开在通过中间电极153与第二电泳流体162之间的相互配合，实现对外界光线进行反射的同时，还可减小在流通孔1531处、以及电泳粒子之间的间隙处的外界光线反射率的损失，从而可提升显示面板1的显示亮度。
本公开实施例中，第一透光电极151可以位于第一基板11靠近第二基板12的一侧，第二透光电极152可以位于第二基板12靠近第一基板11的一侧，但不限于此，也可以将第一透光电极151设置于第一基板11远离第二基板12的一侧，将第二透光电极152设置于第二基板12远离第一基板11的一侧，具体可根据实际情况而定。
当第一透光电极151位于第一基板11靠近第二基板12的一侧，第二透光电极152位于第二基板12靠近第一基板11的一侧时，可将第一透光电极151和第二透光电极152设置于封闭腔室14内，由于第一透光电极151和第二透光电极152位于封闭腔室14所在结构层中，可减少显示面板1整体的厚度，实现显示面板1的轻薄化。
本公开实施例在第一透光电极151、第二透光电极152和中间电极153中至少一者的表面覆盖有介电绝缘层。
要说明的是，第一电泳流体161及第二电泳流体162均为带电流体，当电泳流体与驱动电极组15中的电极直接接触时，容易发生短路现象，通过在第一透光电极151、第二透光电极152和中间电极153中至少一者的表面覆盖介电绝缘层，可降低电泳流体与驱动电极组15中的电极直接接触而出现短路，并导致显示面板1烧毁的问题，继而可延长显示面板1的使用寿命。
举例而言，中间电极153位于封闭腔室14内，可以在中间电极153的表面设置一层介电绝缘层，以减少中间电极153与电泳流体之间的接触，进而降低驱动电极组15出现短路的可能性。当第一透光电极151和第二透光电极152设置于封闭腔室14内时，还可以在第一透光电极151和第二透光电极152的表面均设置介电绝缘层，以减少第一透光电极151和第二透光电极152与电泳流体直接接触，并导致驱动电极组15出现短路的可能性，以延长显示面板1的使用寿命。
要说明的是，中间电极153的侧边与挡墙13的侧边相接，当第一透光电极151和第二透光电极152位于封闭腔室14内时，也可以将第一透光电极151和第二透光电极152的侧边与挡墙13的侧边相接，以减少第一透光电极151设置于第一基板11上、第二透光电极152设置于第二基板12上后，需要将第一透光电极151、第二透光电极152与封闭腔室14之间进行精准对位的工序，从而降低了显示面板1的制作难度。
此外，通过将第一透光电极151、第二透光电极152和中间电极153的侧边与挡墙13的侧边相接，可以减少在挡墙13与第一透光电极151、第二透光电极152及中间电极153之间设置其他连接结构，在避免其他连接结构对显示面板1的像素区的占用，提升显示面板1的像素开口率的同时，还可降低显示面板1的制造成本。
应当理解的是，通过控制施加于各驱动电极组15中第一透光电极151、第二透光电极152及中间电极153上的电压，可控制各驱动电极组15在与其对应的封闭腔室14内形成电场，电场可驱动对应封闭腔室14内的电泳流体的运动，以使封闭腔室14内的第一电泳流体161及第二电泳流体162形成沿竖直方向Y分布的多种位置关系，从而可利用第一电泳流体161及第二电泳流体162实现对外界光线的吸收与反射，以实现显示面板1的显示功能，通过第一电泳流体161及第二电泳流体162在竖直方向Y分布的多种位置关系进行调整，还可实现显示面板1显示效果的多样性。
本公开实施例在第一基板11和第二基板12之间形成多个水平方向X上排布的封闭腔室14，并设置多组与封闭腔室14一一对应的驱动电极组15，通过控制驱动电极组15中第一透光电极151、第二透光电极152和中间电极153上的电压，以控制第一电泳流体161及第二电泳流体162在封闭腔室14内的排布，从而可根据显示面板1的显示亮度与外界环境光，控制显示面板1对外界环境光进行吸收或反射，使显示面板1实现显示功能。同时，当中间电极153未施加电压，第一透光电极151及第二透光电极152在封闭腔室14内形成电场时，封闭腔室14内的第一电泳流体161及第二电泳流体162在竖直方向Y上分为两层，显示面板1可实现单面显示；当中间电极153与第一透光电极151、中间电极153与第二透光电极152分别在封闭腔室14内形成电场时，封闭腔室14内的第一电泳流体161及第二电泳流体162在竖直方向Y上分为三层，显示面板1可实现双面显示。
要说明的是，第一电泳流体161及第二电泳流体162在封闭腔室14内的多种位置关系，可包括第一位置关系、第二位置关系、第三位置关系和第四位置关系中的至少两者。
具体而言，如图1所示，在第一位置关系中：第一电泳流体161位于第二电泳流体162靠近第一基板11的一侧，此时，封闭腔室14内的第一电泳流体161及第二电泳流体162在竖直方向Y上分为上下两层，且第一电泳流体161对从第一基板11一侧进入的外界光线进行吸收，第二电泳流体162及中间电极153中的至少一者对从第二基板12一侧进入的外界光线进行反射。
如图2所示，在第二位置关系中：第一电泳流体161位于第二电泳流体162靠近第二基板12的一侧，此时，封闭腔室14内的第一电泳流体161及第二电泳流体162在竖直方向Y上分为上下两层，且第一电泳流体161对从第二基板12一侧进入的外界光线进行吸收，第二电泳流体162及中间电极153中的至少一者对从第一基板11一侧进入的外界光线进行反射。
如图3所示，在第三位置关系中：第一电泳流体161的一部分位于第二电泳流体162靠近第一基板11的一侧，另一部分位于第二电泳流体162靠近第二基板12的一侧，此时，封闭腔室14内的第一电泳流体161及第二电泳流体162在竖直方向Y上分为上中下三层，第二电泳流体162被上下两层的第一电泳流体161遮蔽，第一电泳流体161对从第一基板11一侧进入的外界光线以及从第二基板12一侧进入的外界光线进行吸收。
如图4所示，在第四位置关系中：第二电泳流体162的一部分位于第一电泳流体161靠近第一基板11的一侧，另一部分位于第一电泳流体161靠近第二基板12的一侧，此时，封闭腔室14内的第一电泳流体161及第二电泳流体162在竖直方向Y上分为上中下三层，第一电泳流体161被上下两层的第二电泳流体162覆盖，第二电泳流体162及中间电极153中的至少一者对从第一基板11一侧进入的外界光线以及从第二基板12一侧进入的外界光线进行反射。
在第一种位置关系及第二种位置关系中，封闭腔室14内的第一电泳流体161及第二电泳流体162分为上下两层，一层为吸收外界光线的第一电泳流体161，另一层为可与中间电极153配合实现对外界光线的反射的第二电泳流体162，通过控制电泳流体在第一位置关系及第二位置关系中切换，可实现显示面板1的单面显示。
在第三种位置关系及第四种位置关系中，封闭腔室14内的第一电泳流体161及第二电泳流体162分为上中下三层，上下两层为第一电泳流体161时，中间层则相应设置为第二电泳流体162；上下两层为第二电泳流体162时，对应的，中间层则相应设置为第一电泳流体161。通过控制电泳流体在第三位置关系及第四位置关系中切换，可实现显示面板1的双面显示。
要说明的是，当电泳流体处于第三位置关系及第四位置关系时，位于中间层的电泳流体与中间电极153之间的位置关系，与第一电泳流体161、第二电泳流体162的体积、以及中间电极153在流通孔1531区域内的体积有关。
举例而言，若第一电泳流体161位于中间层，且第一电泳流体161的体积小于或者等于中间电极153在流通孔1531所处区域的体积时，位于中间层的电泳流体仅位于中间电极153的流通孔1531所处区域；当第一电泳流体161的体积大于中间电极153在流通孔1531所处区域的体积时，位于中间层的电泳流体除位于中间电极153的流通孔1531所处区域外，还可能部分覆盖于中间电极153靠近第一基板11及第二基板12的表面。
进一步的，在第一电泳流体161和第二电泳流体162处于第一位置关系时，第一透光电极151所带电压的极性与第一电泳流体161所带电荷的极性相反，第二透光电极152所带电压的极性与第二电泳流体162所带电荷的极性相反，中间电极153处于不通电状态；第一透光电极151和第二透光电极152可在封闭腔室14内形成电场，且在电场的作用下，第一电泳流体161可朝靠近第一透光电极151的方向移动，第二电泳流体162可朝靠近第二透光电极152的方向移动。
在第一电泳流体161和第二电泳流体162处于第二位置关系时，第一透光电极151所带电压的极性与第二电泳流体162所带电荷的极性相反，第二透光电极152所带电压的极性与第一电泳流体161所带电荷的极性相反，中间电极153处于不通电状态；第一透光电极151和第二透光电极152可在封闭腔室14内形成电场，且在电场的作用下，第一电泳流体161可朝靠近第二透光电极152的方向移动，第二电泳流体162可朝靠近第一透光电极151的方向移动。
在第一电泳流体161和第二电泳流体162处于第三位置关系时，第一透光电极151和第二透光电极152所带电压的极性与第一电泳流体161所带电荷的极性相反，中间电极153所带电压的极性与第二电泳流体162所带电荷的极性相反；中间电极153与第一透光电极151之间、中间电极153与第二透光电极152之间分别形成电场，且电场的方向相反。在电场的作用下，第二电泳流体162可朝靠近中间电极153的方向移动，第一电泳流体161则朝远离中间电极153的方向移动，第一电泳流体161位于第二电泳流体162的上下两侧，并对第二电泳流体162形成遮蔽，从而第一电泳流体161可对来自第一基板11及第二基板12侧的外界光线进行吸收。
在第一电泳流体161和第二电泳流体162处于第四位置关系时，第一透光电极151和第二透光电极152所带电压的极性与第二电泳流体162所带电荷的极性相反，中间电极153所带电压的极性与第一电泳流体161所带电荷的极性相反；中间电极153与第一透光电极151之间、中间电极153与第二透光电极152之间分别形成电场，且电场的方向相反，在电场的作用下，第一电泳流体161可朝靠近中间电极153的方向移动，第二电泳流体162则朝远离中间电极153的方向移动，第二电泳流体162覆盖于第一电泳流体161的上下两侧，第二电泳流体162与中间电极153配合，以对来自第一基板11及第二基板12侧的外界光线进行反射。
如图1、图2、图3、图4及图6所示，驱动电极组15中，可以设置一个中间电极153，通过控制中间电极153与第一透光电极151、第二透光电极152上的电压，可实现电泳流体在第一位置关系、第二位置关系、第三位置关系及第四位置关系之间的切换。
当驱动电极组15中设置一个中间电极153时，可以将第二电泳流体162设置为用于反射光线的电泳流体，从而第二电泳流体162可将与中间电极153的流通孔1531位置处对应的外界光线进行反射，以减少中间电极153在流通孔1531位置处对外界光线反射率的损失。但不限于此，当驱动电极组15中设置一个中间电极153时，第二电泳流体162也可以设置为用于透光的电泳流体，具体可根据实际情况而定。
进一步的，如图7所示，在驱动电极组15中，可以设置四个中间电极153，且四个中间电极153沿竖直方向Y间隔排列；其中，四个中间电极153可分为两组，每组中包括两个相邻排布的中间电极153，在每组中：两中间电极153的流通孔1531在第一基板11上的正投影不存在交叠，当外界光线照射至其中一组时，部分外界光线通过该组内的第一个中间电极153的非通孔区域进行反射，部分外界光线通过该组内的第一个中间电极153的流通孔1531照射至第二个中间电极153的非通孔区域，并通过第二个中间电极153的非通孔区域进行反射。
本公开通过在驱动电极组15中设置四个中间电极153，且将相邻排布的两个中间电极153分为一组，每组内的中间电极153上的流通孔1531交错排布，外界光线照射至一组中间电极153上时，外界光线可通过该组内的两个中间电极153实现反射，以实现显示面板1的亮态实现，同时，本公开实施例通过在驱动电极组15中设置四个中间电极153，还可减少中间电极153在流通孔1531处对外界光线的反射率的损失，进而可提升显示面板1的显示亮度。
此外，本公开实施例在驱动电极组15中设置四个中间电极153，由于四个中间电极153沿竖直方向Y一次排布，可以缩短中间电极153与第一透光电极151及第二透光电极152之间的距离，从而可以缩短第一电泳流体161及第二电泳流体162变更位置关系的响应时间，以提高显示面板1的显示画面的刷新率以及显示面板1的显示效果。
但不限于此，驱动电极组15中设置的中间电极153的数量还可为两个、三个、五个、六个、七个、八个等等，当驱动电极组15中的中间电极153设置有四个以上时，所有中间电极153可分为两组，且每组中至少包括两个中间电极153。每组中的中间电极153包括主电极和辅助电极，主电极由一个中间电极153组成，除主电极以外的其他中间电极153共同组成辅助电极，主电极位于辅助电极远离另一组中间电极153的一侧，辅助电极的非通孔区域在第一基板11上的正投影覆盖主电极上的流通孔1531在第一基板11上的正投影，从而可减少中间电极153在流通孔1531位置处对外界光线反射率的损失，提升显示面板1的显示亮度。
此外，驱动电极组15还可包括与第一透光电极151和第二透光电极152间隔设置的连接电极，连接电极位于中间电极153靠近挡墙13的一侧，并与中间电极153连接。中间电极153可通过连接电极获得电压，通过将连接电极与第一透光电极151及第二透光电极152间隔设置，可降低连接电极与第一透光电极151及第二透光电极152接触后发生短路的概率，以延长显示面板1的使用寿命。
当驱动电极组15中设置有四个中间电极153时，连接电极可同时与四个中间电极153连接，从而四个中间电极153可通过同一连接电极获得相同的电压，同时，相比于设置多个连接电极分别与四个中间电极153，本公开通过设置一个连接电极分别与四个中间电极153连接，可减少使用连接电极，从而可降低显示面板1的制作成本。
当连接电极与四个中间电极153连接时，四个中间电极153与第一透光电极151之间形成相同的电场，四个中间电极153与第二透光电极152之间形成相同的电场，且四个中间电极153相互之间不产生电场，当中间电极153不与第一透光电极151及第二透光电极152之间产生电场时，第一电泳流体161及第二电泳流体162可在第一透光电极151及第二透光电极152的共同作用下，在竖直方向Y上形成上下两层，也即：电泳流体处于上述中的第一位置关系及第二位置关系。当中间电极153从连接电极上获得电压，并与第一透光电极151及第二透光电极152之间产生电场时，第一电泳流体161及第二电泳流体162可在中间电极153及第一透光电极151、第二透光电极152的共同作用下，在竖直方向Y上形成上中下三层，也即：电泳流体处于上述中的第三位置关系及第四位置关系。
如图8所示，显示面板1还可包括第一色阻层17，第一色阻层17位于第一基板11远离第二基板12的一侧，但不限于此，第一色阻层17也可设置于第一基板11靠近第二基板12的一侧，通过设置第一色阻层17，可使显示面板1在第一基板11远离第二基板12的一侧实现彩色显示。
此外，显示面板1还可包括显示功能层18，显示功能层18可以包括驱动电路层181、像素界定层、多个有机发光部182和透光阴极层184。
驱动电路层181形成在第二基板12远离第一基板11的一侧，驱动电路层181包括多个间隔排布的透光阳极1811，透光阳极1811与封闭腔室14沿竖直方向Y一一相对。像素界定层形成在驱动电路层181远离第二基板12的一侧，像素界定层包括与封闭腔室14沿竖直方向Y一一对应的像素开口区和与挡墙13沿竖直方向Y对应的非开口区，具体的，封闭腔室14在第二基板12上的正投影可以与像素开口区重合，挡墙13在第二基板12上的正投影可以与非开口区重合，各有机发光部182形成在一像素开口区内，并与一透光阳极1811相接；透光阴极层184覆盖于各有机发光部182远离透光阳极1811的表面。
本公开实施例中的透光阳极1811和透光阴极层184均具有透光性和导电性，外界光线照射至显示面板1时，可透过透光阳极1811和透光阴极层184，照射至封闭腔室14内的电泳流体上，从而可根据外界光线亮度与显示功能层18待显示画面对应的显示亮度之间的关系，控制第一电泳流体161及第二电泳流体162在封闭腔室14内的位置关系。在外界光线大于显示功能层18待显示画面对应的显示亮度时，可控制电泳流体对外界光线进行吸收，以使显示功能层18一侧的显示面实现暗态更暗的显示效果；在外界光线小于或等于显示功能层18待显示画面对应的显示亮度时，可控制电泳流体对外界光线进行反射，以使显示功能层18一侧的显示面实现亮态更亮的显示效果，进而本公开可通过调整第一电泳流体161及第二电泳流体162的位置关系，提升显示功能层18一侧的显示面的显示对比度。
进一步的，显示功能层18还可包括多个像素界定部183，像素界定部183环绕有机发光部182设置，像素界定部183位于非开口区内，并与挡墙13沿竖直方向Y上对应设置。
具体的，像素界定部183在第二基板12上的正投影可以与挡墙13在第二基板12上的正投影重合，通过设置像素界定部183，可以将各有机发光部182之间进行隔离，避免相邻像素开口区之间出现光串扰或电信号干扰的问题，以保证各像素开口区的清晰度和准确性，提高显示面板1的显示效果和对比度。此时，透光阴极层184可整层覆盖于像素界定部183及有机发光部182远离透光阳极1811的一侧，以减少设置为透光阴极层184供电的连接线路，降低显示面板1的制作成本。
要说明的是，上述中“像素界定层形成在驱动电路层181远离第二基板12的一侧”指的是，像素界定层在驱动电路层181之后形成。在形成像素界定层时，透光阳极1811的至少部分暴露于像素开口区，以使透光阳极1811与有机发光部182接触。当透光阴极层184发射的电子与透光阳极1811输送的空穴在有机发光部182中结合时，能量以光子的形式释放，从而使有机发光部182产生发光现象。通过使阳极与有机发光部182接触，可以确保电子和空穴在有机发光部182中有效结合，从而使有机发光部182发射光线。
显示功能层18中还可包括封装层186，封装层186位于透光阴极层远离第二基板12的一侧。
本公开实施例中的封装层186可以为有机无机封装层。
具体的，可以先通过化学气相沉积(Chemical Vapor Deposition，CVD)工艺形成第一无机封装层，第一无机封装层具有较高的硬度和良好的阻隔性能，可将第一无机封装层靠近第二基板12一侧的结构层与外界水汽进行隔离，降低结构层与水汽接触后发生氧化腐蚀的风险。然后可以在第一无机封装层远离第二基板12的一侧形成有机封装层，以对第一无机封装层的表面进行填平，有机封装层具有较好的柔韧性和应力缓冲能力，能够吸收和分散一部分应力，从而可降低第一无机封装层在应力作用下产生裂纹或缺陷的可能性，保护第一无机封装层免受损伤。在有机封装层远离第二基板12的一侧再通过化学气相沉积工艺形成一层第二无机封装层，通过第二无机封装层，可以将第二无机封装层靠近第二基板12的一侧的结构层与外界水汽进行隔离保护，以进一步降低显示面板1中的结构层与水汽接触后发生氧化腐蚀的风险。
在本公开的一种实施例中，各有机发光部182用于发射白色光线，此时，显示功能层18还可包括第二色阻层185，第二色阻层185位于透光阴极层184远离第二基板12的一侧。
要说明的是，当显示面板1中设置有第二色阻层185时，封装层186可位于第二色阻层185靠近第二基板12的一侧，具体的，封装层186可位于第二色阻层185及透光阴极层184之间；但不限于此，封装层186也可设置于第二色阻层185远离第二基板12的一侧，具体可根据实际情况进行设定。
进一步的，色阻层可包括多种不同颜色的色阻块，色阻块与有机发光部182沿竖直方向Y上一一对应设置。
举例而言，色阻层中可以包括红色色阻块、绿色色阻块和蓝色色阻块，三种色阻块之间阵列间隔排布，且色阻块在第二基板12上的正投影与有机发光部182在第二基板12上的正投影重合。通过设置第二色阻层185，可以对有机发光部182发射的白色光线进行过滤，进而可实现显示面板1的彩色显示。
要说明的是，当各有机发光部182用于发射白色光线时，本公开实施例中可以在第二基板12远离第一基板11的一侧设置第二色阻层185，并同时在第一基板11远离第二基板12的一侧设置第一色阻层17，从而当电泳流体在第三位置关系和第四位置关系之间切换时，可以实现显示面板1的双面彩色显示。
在本公开的另一种实施例中，多个有机发光部182中至少部分有机发光部182用于发射不同颜色的光线。
举例而言，多个有机发光部182可以包括红色发光部、绿色发光部和蓝色发光部，用于分别发射红色光线、绿色光线和蓝色光线，但不限于此，也可设置除红色、绿色、蓝色以外的其他颜色的有机发光部182，利用有机发光部182发射不同颜色的光，从而可实现显示面板1的彩色显示，同时，还可减少色阻层的设置，以降低显示面板1的厚度，并可减少色阻层对出射光线的阻挡，以实现显示面板1的轻薄化，并可提升光线出射率。
此外，本公开实施例还可以在封闭腔室14内设置彩色的第二电泳流体162，通过彩色的第二电泳流体162与中间电极153之间的配合，以实现对外界光线的反射。
具体的，当第二电泳流体162为彩色的反射流体时，可以将反射层的表面设置为白色的反射面或者与第二电泳流体162颜色相同的反射面，以在第二电泳流体162及中间电极153的配合下实现显示面板1的彩色显示；但不限于此，本公开实施例中的第二电泳流体162也可以为透光电泳流体，此时，可将中间电极153的表面设置为红、绿、蓝等多种颜色的反射层，从而也可在第二电泳流体162及中间电极153的配合下实现显示面板1的彩色显示。
如图9所示，本公开提供了一种显示面板1的驱动方法，驱动方法用于驱动上述中的任一显示面板1，驱动方法包括：
S1、探测外界环境光线以及显示功能层待显示画面对应的灰阶像素；
S2、根据探测到的外界环境光线与标准光线强度之间的关系，以及灰阶像素与标准灰阶像素之间的关系，控制对应驱动电极组中第一透光电极、中间电极和第二透光电极上的电压，以确定对应封闭腔室内第一电泳流体和第二电泳流体沿竖直方向分布的位置关系。
要说明的是，本公开实施例中的驱动方法用于驱动上述中具有显示功能层18的显示面板1，在显示功能层18一侧进行显示面板1的画面显示的同时，可根据外界环境光线的情况以及显示功能层18待显示画面对应的灰阶像素的实时情况，调整各封闭腔室14内的第一电泳流体161及第二电泳流体162沿竖直方向Y分布的位置关系，在显示功能层18一侧的显示面处于暗态显示时，通过对外界光线进行吸收，可使显示功能层18一侧的显示面实现暗态更暗的显示效果；在显示功能层18一侧的显示面处于亮态显示时，通过对外界光线进行反射，可使显示功能层18一侧的显示面实现亮态更亮的显示效果，进而可提升显示功能层18一侧的显示面的显示对比度。
具体的，在外界环境光线低于或者等于标准光线强度时，可控制每组驱动电极组15中第一透光电极151、中间电极153和第二透光电极152上无电压施加，或者控制第一透光电极151、中间电极153和第二透光电极152上施加相同的电压，以使封闭腔室14中第一电泳流体161和第二电泳流体162散乱分布。
在仅显示功能层18所在一侧为显示侧时，若外界环境光线高于标准光线强度，且灰阶像素高于标准灰阶像素，控制对应驱动电极组15中第一透光电极151所带电压的极性与第一电泳流体161所带电荷的极性相反，第二透光电极152所带电压的极性与第二电泳流体162所带电荷的极性相反，中间电极153处于不通电状态，以使对应封闭腔室14内的第一电泳流体161位于第二电泳流体162靠近第一基板11的一侧。第二电泳流体162及中间电极153对外界光线的反射时，反射的外界光线可增强显示功能层18一侧的显示面的显示亮度，以使显示功能层18一侧的显示面具有亮态更亮的显示效果。
在仅显示功能层18所在一侧为显示侧时，若外界环境光线高于标准光线强度，且灰阶像素低于或者等于标准灰阶像素，控制对应驱动电极组15中第一透光电极151所带电压的极性与第二电泳流体162所带电荷的极性相反，第二透光电极152所带电压的极性与第一电泳流体161所带电荷的极性相反，中间电极153处于不通电状态，以使对应封闭腔室14内的第一电泳流体161位于第二电泳流体162靠近第二基板12的一侧。通过第一电泳流体161吸收外界光线，可以减少显示功能层18一侧的显示面因外界光线的反射而出现的光晕问题，同时还可降低显示功能层18一侧的显示面的显示亮度，以使显示功能层18一侧的显示面具有暗态更暗的显示效果。
在显示功能层18所在一侧和第一基板11所在的一侧均为显示侧时，外界环境光线高于标准光线强度，且显示面板1显示画面的灰阶像素低于或者等于标准灰阶像素，控制对应驱动电极组15中第一透光电极151和第二透光电极152所带电压的极性与第一电泳流体161所带电荷的极性相反，中间电极153所带电压的极性与第二电泳流体162所带电荷的极性相反，以使对应封闭腔室14内的第一电泳流体161的一部分位于第二电泳流体162靠近第一基板11的一侧，另一部分位于第二电泳流体162靠近第二基板12的一侧。通过第一电泳流体161吸收外界光线，可以减少显示功能层18所在一侧的显示面因外界光线的反射而出现的光晕问题，同时还可降低显示功能层18所在一侧的显示面的显示亮度，以使显示功能层18所在一侧的显示面具有暗态更暗的显示效果。
在显示功能层18所在一侧和第一基板11所在的一侧均为显示侧时，外界环境光线高于标准光线强度，且显示面板1显示画面的灰阶像素高于标准灰阶像素，控制对应驱动电极组15中第一透光电极151和第二透光电极152所带电压的极性与第二电泳流体162所带电荷的极性相反，中间电极153所带电压的极性与第一电泳流体161所带电荷的极性相反，以使对应封闭腔室14内的第二电泳流体162的一部分位于第一电泳流体161靠近第一基板11的一侧，另一部分位于第一电泳流体161靠近第二基板12的一侧。通过第二电泳流体162及中间电极153对外界光线的反射时，反射的外界光线可增强显示功能层18所在一侧的显示面的显示亮度，以使显示功能层18所在一侧的显示面具有亮态更亮的显示效果。
要说明的是，“显示面”为显示面板1用于呈现显示画面的一面，当仅显示功能层18所在一侧为显示侧时，显示面板1为单面显示；当显示功能层18所在一侧和第一基板11所在的一侧均为显示侧时，显示面板1为双面显示。
第一透光电极151、中间电极153和第二透光电极152上不施加电压，或者给第一透光电极151、中间电极153和第二透光电极152上施加相同的电压时，第一透光电极151、中间电极153和第二透光电极152在封闭腔室14内不形成电场，从而不会控制第一电泳流体161及第二电泳流体162定向运动，第一电泳流体161及第二电泳流体162在封闭腔室14中散乱分布，但不限于此，若在封闭腔室14内形成电泳流体的初始状态时，第一电泳流体161及第二电泳流体162在封闭腔室14内即自动分布为上下分层排布的状态，也包含在本公开的范围内。
如图10所示，本公开实施例提供了一种显示装置5，显示装置5包括外界光线探测器3、画面预处理器4、控制器2以及如上述中的任一显示面板1，外界光线探测器3用于探测外界环境光线，画面预处理器4用于检测显示面板1显示画面的灰阶像素，根据探测到的外界环境光线与标准光线强度之间的关系，以及显示功能层18待显示画面对应的灰阶像素与标准灰阶像素之间的关系，控制第一透光电极151、中间电极153和第二透光电极152上的电压，以改变第一电泳流体161和第二电泳流体162沿竖直方向Y分布的位置关系，以使显示功能层18一侧的显示面实现亮态更亮、暗态更暗的显示效果，提升显示装置5的显示对比度。
要说明的是，本公开实施例中，显示装置5中的显示面板1为上述中具有显示功能层18的显示面板1，从而显示装置5可在显示功能层18一侧实现画面显示的同时，还可根据外界环境光线的实时情况以及显示功能层18待显示画面对应的灰阶像素的实时情况，控制对应驱动电极组15中第一透光电极151、中间电极153和第二透光电极152上的电压，以确定对应封闭腔室14内第一电泳流体161和第二电泳流体162沿竖直方向Y分布的位置关系。在显示功能层18一侧的显示面处于暗态显示时，通过对外界光线进行吸收，可使显示功能层18一侧的显示面实现暗态更暗的显示效果；在显示功能层18一侧的显示面处于亮态显示时，通过对外界光线进行反射，可使显示功能层18一侧的显示面实现亮态更亮的显示效果，进而可提升显示装置5整体的显示对比度。
具体的，可以将控制器2分别与显示面板1、外界光线探测器3及画面预处理器4连接，外界光线探测器3将探测到的外界光线的数据信号传送至控制器2，画面预处理器4也将检测到的显示功能层18待显示画面对应的灰阶像素的数据信号传输至控制器2，控制器2接收数据信号，并可根据预设程序，控制施加于第一透光电极151、第二透光电极152、中间电极153上的电压的大小。
当外界环境光线低于或者等于标准光线强度时，通过控制器2可控制不予显示装置5中的第一透光电极151、中间电极153和第二透光电极152上施加电压，或者给第一透光电极151、中间电极153和第二透光电极152上施加相同的电压，使得封闭腔室14中不形成电场，第一电泳流体161及第二电泳流体162在封闭腔室14内散乱分布。
当外界环境光线高于标准光线强度，且显示面板1显示画面的灰阶像素高于标准灰阶像素时，通过控制器2控制第二电泳流体162移动至第一电泳流体161靠近显示面的一侧，利用第二电泳流体162对来自于显示功能层18一侧的显示面的外界光线进行反射，以使显示功能层18一侧的显示面实现亮态更亮的显示效果。
当外界环境光线高于标准光线强度，且显示面板1显示画面的灰阶像素低于或者等于标准灰阶像素时，则可通过控制器2控制第一电泳流体161移动至第二电泳流体162靠近显示面的一侧，利用第一电泳流体161对来自于显示功能层18一侧的显示面的外界光线进行吸收，以使显示功能层18一侧的显示面实现暗态更暗的显示效果。
本公开实施例中的显示装置5可以为液晶显示装置(LCD)，但不限于此，显示装置5也可是除液晶显示装置以外的其他显示装置，例如：有机发光二极管显示装置(OLED)等等显示装置，在此不做具体限定。
要说明的是，当第一基板11所在的一侧为显示侧时，由于第一基板11所在的一侧未设置显示功能层18，通过封闭腔室14内的第一电泳流体161及第二电泳流体162对外界光线的吸收及反射，目的在于实现第一基板11所在的一侧的显示功能。当显示面板1中设置有显示功能层18时，若显示功能层18所在一侧和第一基板11所在的一侧均为显示侧，通过调整显示面板1中第一电泳流体161及第二电泳流体162沿竖直方向Y分布的位置关系，在实现显示面板1的显示功能的同时，还可实现对显示功能层18所在一侧的显示面的显示亮度的调整，也即：显示功能层18所在一侧的显示面可通过对第一电泳流体161及第二电泳流体162沿竖直方向Y分布的位置关系的调整，实现亮态更亮、暗态更暗的显示效果，进而可提升显示功能层18所在一侧的显示面的显示对比度。因此，上述中的标准光线强度为针对显示功能层18一侧的显示面设置的标准光线强度，显示面板1显示画面的灰阶像素也为显示功能层18所在一侧的待显示画面对应的灰阶像素。
此外，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一个或者更多个该特征。在本公开的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
需要说明的是，“上”、“下”、“左”、“右”等仅用作区分以方便描述，不对本发明实施例做方位上的限制，比如所述“上”在实际中可以是“下”、“左”、“右”等方位。在本公开中，除非另有明确的规定和限定，术语“装配”、“连接”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本公开中的具体含义。
