Description

显示面板及移动终端 技术领域
本申请涉及显示领域，尤其涉及一种用于显示面板及移动终端。
 背景技术
有机发光半导体（OLED，Organic Light-Emitting Diode）显示屏比液晶显示屏（LCD，Liquid Crystal Display）更轻薄、亮度高、功耗低、响应快、清晰度高、柔性好、发光效率高，能满足消费者对显示技术的新需求。全球越来越多的显示器厂家纷纷投入研发和生产，大大的推动了OLED的产业化进程。
目前，通过将红绿蓝（RGB，Red、Green、Blue）三原色的子像素采用一定的排列方式来实现显示各种颜色。在OLED显示初期，因像素密度（PPI，pixels per inch）较低，通常RGB三原色排布方式采用狭缝式和前景点画式。后来随着ppi的提升，金属光罩的开口率要求越来越大，RGB三原色排布逐步采用像素排列方式，将红色子像素与绿色子像素、绿色子像素与蓝色子像素一起分别形成显示像素单元，整个面板通过不同的像素单元不同排布方式来实现全彩显示，但是这种显示面板的全彩显示存在像素借用，因此其显示效果远不及标准RGB像素排列的显示面板。

 本发明的实施方式
本申请提供一种用于显示模组的调光层及显示模组，为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
本申请实施例提供一种显示面板及其制备方法。以下分别进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
目前的产品设计中，为了追求显示面板10具有较高的PPI，在一像素单元内，通常会采用与其相邻的像素单元共用子像素，例如，红色子像素与绿色子像素形成一像素单元、该绿色子像素又与蓝色子像素形成另一像素单元，整个面板通过不同的像素单元的不同排布方式来实现全彩显示，由于该像素结构实现全彩显示是通过公用相邻像素单元的子像素实现的，虽然该结构具有较高的PPI，但是其显示效果却没有不共用像素的像素结构实现的全彩显示效果好；在显示白光时，该共用像素的像素单元不能够独立显示RGB三种颜色，显示白光时就需要借用相邻像素单元的子像素，造成显示细腻程度下降。
本实施例解决了上述问题，本申请提供了如下技术方案，下面结合附图和实施例对本申请作进一步说明。
参照图1~3、图4~6、图7~8所示，本申请提供一种显示面板10，包括多个子像素，所述多个子像素包括：
多个显示第一颜色的第一子像素201，所述第一子像素201包括第一电极和设置在所述第一电极上的第一发光层，
多个显示第二颜色的第二子像素202，所述第二子像素202包括第二电极和设置在所述第二电极上的第二发光层，
多个显示第三颜色的第三子像素203，所述第三子像素203包括第三电极和设置在所述第三电极上的第三发光层，所述第三发光层与至少两个相邻设置的所述第三电极重叠设置；
所述显示面板10还包括多个发光重复单元，每一所述发光重复单元包括两相邻设置的发光单元组101，每一所述发光单元组101包括：
一所述第一子像素201，设置在一虚拟矩形的中心；
至少一所述第二子像素202，设置在所述虚拟矩形内且靠近所述虚拟矩形的侧边设置；
至少两所述第三子像素203，设置在所述虚拟矩形内且与所述虚拟矩形的一公共侧边300相邻接，所述公共侧边300为所述虚拟矩形与另一相邻的发光单元组101的所述虚拟矩形邻接的侧边；
其中，所述发光单元组101内的至少两所述第三子像素203的所述第三电极通过第一导线电连接；
每个所述发光重复单元中，两个相邻的发光单元组101包括至少两个相邻的所述第三子像素203。
具体地，所述显示面板10包括：多个显示第一颜色的第一子像素201，多个显示第二颜色的第二子像素202，多个显示第三颜色的第三子像素203；第一子像素201、第二子像素202、第三子像素203结构均包括一个、两个或多个驱动组件、与驱动组件连接的像素电极、与像素电极相对设置的阴极、位于像素电极与阴极之间的有机发光层；第一子像素201、第二子像素202、第三子像素203按照下述的结构排列于基板上，形成有机发光显示面板10。
具体地，所述显示面板10还包括多个相邻排列的发光重复单元，多个发光重复单元可以为行列排布的点阵结构，相邻的发光重复单元边缘互相邻接。
具体地，每一所述发光重复单元包括两相邻设置的发光单元组101，每一发光单元组101包括：
一所述第一子像素201，可以为蓝色子像素，设置在一虚拟矩形的中心处，其形状不作限制，可以理解的是，将第一子像素201设置于中心位置能够使得像素结构排列结构更合理，发光更均匀，同时也方便后续的金属走线制程；
至少一所述第二子像素202，可以为绿色子像素，其形状不作限制，设置在所述虚拟矩形内且靠近所述虚拟矩形的侧边设置，此处的侧边不做限制，可以为两相邻发光单元组101的虚拟矩形的公共侧边300，如图4所示；也可以位于发光单元组101的虚拟矩形的非公共侧边，图5、图6所示；具体地，所述第二子像素202也可以位于所述虚拟矩形远离公共侧边300的边角处，如图1~3所示；
至少两所述第三子像素203，需要注意的是，同一发光单元组101内的多个第三子像素203之间存在间隙，第三子像素203可以为红色子像素，设置在所述虚拟矩形内且与所述虚拟矩形的一公共侧边300相邻接，所述公共侧边300为所述虚拟矩形与另一相邻的发光单元组101的所述虚拟矩形邻接的侧边；
其中，如图3a所示，所述发光单元组101内的至少两所述第三子像素203的所述第三电极通过第一导线电连接，使得同一发光单元组101内同色的第三子像素203能够同步驱动。
每个所述发光重复单元中，两个相邻的发光单元组101包括至少两个相邻的所述第三子像素203，两相邻的第三子像素203对应的两第三电极与一第三发光层重叠设置，可以理解为，在发光重复单元中，由于发光单元组101内的第三子像素203均与所述虚拟矩形的一公共侧边300相邻接，且一个发光单元组101内的至少两个第三子像素203之间是存在间隔的，因此前述的至少两个相邻设置的所述第三电极分别位于两个发光单元组101内，通过该设置方式，使得发光重复单元中，相邻的两发光单元组101中相邻的两第三子像素203能够共用一个第三发光层，使得显示面板10实现全彩显示的同时，也能够降低显示面板10的光罩制作难度，提高成产良率，降低生产国中的混色概率。
具体地，至少两所述第三子像素203的所述第三电极通过第一导线电连接的方式如图3a所示，图3a为图3的A-A’的截面图，其中，ANO为第三子像素203的阳极，用于连接驱动单元后配合阴极驱动发光层发光，EL1为第三子像素203的电子传输层和电子注入层，EL2为空穴注入层和空穴传输层，CAT为第三子像素203的阴极，EML为发光层，ST为开关控制单元，DT为驱动单元，GI为栅极绝缘层，PL为平坦层，ENC为封装层，通过图3a可以看出两个第三子像素203的阳极是串连在一起的，通过一个驱动单元和开关控制单元控制，进而实现同步开关。
通过在每一发光单元组101内设置第一子像素201，第二子像素202和第三子像素203，使得一个发光单元组101不需要借助相邻结构的子像素就能够实现白光显示，有效提升了显示面板10的显示效果，使得显示面板10的显示色彩更加丰富；同时，如图3a所示，一单一发光单元组101内有两个第三子像素203为例，发光单元组内的两个第三子像素203对应的两第三电极通过第一导线串连，使得同一发光单元组101内的同色两第三子像素203实现同开或通关，降低了显示面板10显示异常的风险，有效提升了器件性能。
可以理解的是，本申请通过在显示面板10内设置多个发光重复单元，每个发光重复单元包括两相邻设置的发光单元组101，每一发光单元组101包括一第一子像素201、至少一第二子像素202和至少两第三子像素203，其中，在发光单元组101内，至少两所述第三子像素203的第三电极通过第一导线电连接，使得一个发光单元组101不需要借助相邻结构的子像素就能够实现白光显示，有效提升了显示面板10的显示效果，使得显示面板10的显示色彩更加丰富，在单一的发光单元组101内通过第一导线串连同色的至少两个第三电极，使得发光单元组101内的第三像素能够同步驱动，降低显示异常的风险，提升器件性能；两个相邻的发光单元组101包括至少两个相邻的第三子像素203，相邻的两第三子像素203对应的两第三电极与一第三发光层重叠，使得本申请的结构在实现全彩显示的同时，相同颜色的子像素可以共用一个光罩开口，降低了光罩的设计与生产难度。
本实施例中，如图3和图4所示，每一所述发光单元组101包括至少两所述第二子像素202，所述发光单元组101的至少两所述第二子像素202的所述第二电极通过第二导线电连接。
具体地，当一个发光单元组101包括至少两所述第二子像素202时，设置第二导线，将同一发光单元组101内的至少两第二子像素202对应的第二电极串连，使得多个第二子像素202能够同步驱动，其具体连接结构和多个第三子像素203的连接结构相同。
可以理解的是，通过在同一发光单元组101内设置三种颜色的子像素，一个第一子像素201，至少两个第二子像素202，至少两个第三子像素203，使得一个发光单元组101不需要借助相邻结构的子像素就能够实现白光显示，有效提升了显示面板10的显示效果，使得显示面板10的显示色彩更加丰富，设置至少两个第二子像素202以及设置至少两个第三子像素203能够使得发光单元组101的发光更均匀，同时，在单一的发光单元组101内通过第一导线串连同色的至少两个第二像素电极，使得发光单元组101内的多个第二像素能够同步驱动，降低显示异常的风险，提升器件性能。
本实施例中，如图1所示，所述第二发光层与至少两个相邻设置的所述第二电极重叠设置，相邻两所述发光重复单元的多个所述第二子像素202至少包括一个第二子像素202组，每一所述第二子像素202组包括至少两所述第二子像素202，该至少两所述第二子像素202分别位于两所述发光重复单元内且互相相邻设置。
具体地，所述第二像素组内的第二子像素202位于所述虚拟矩形非公共侧边的侧边上，使得相邻两所述发光重复单元的两相邻第二子像素202紧贴设置，使得相邻的两第二子像素202能够共用一个光罩上的开口。
可以理解的是，通过将第二像素组内的第二子像素202设置在所述虚拟矩形靠近边缘的位置，使得相邻的两个或多个发光重复单元内相邻接的同色子像素能够互相拼接，形成一个大的同色子像素，在进行显示面板10的生产过程中，对同色的子像素，可以采用一个光罩开口，降低了光罩开口的精细度，降低了光罩的制作难度，提高生产效率，降低混色的概率，提升产品生产良率。
本实施例中，如图1~3、图7~8所示，一所述虚拟矩形内设有两所述第二子像素202，且两所述第二子像素202分别设置于所述虚拟矩形远离所述公共侧边300一侧的两顶角，任意四个互相相邻的所述发光重复单元中，互相相邻的四个所述第二子像素202共用一个所述第二发光层，且该所述第二发光层与四个所述第二电极重叠设置。
可以理解的是，通过将第二子像素202设置于虚拟矩形远离所述公共侧边300的两个顶角处，多个重复单元在基板上排列后，互相相邻的四个所述第二子像素202在顶角处聚集，形成一个由四个第二子像素202拼接的拼接第二子像素202，由于四个第二子像素202的颜色相同，且相互相邻接，因此可以公用一个像素开口，进一步增大了像素的开口率，降低了该像素掩膜板的制备难度，提高了产品的生产良率。
本实施例中，如图1、图5~图6a所示，一所述虚拟矩形内设有两所述第三子像素203，且两所述第三子像素203分别设置于该所述虚拟子矩形靠近所述公共侧边300一侧的两顶角，如图6所示，在平行所述公共侧边300方向上，任意相邻的两所述发光重复单元中，具有互相相邻的四个所述第三子像素203，四个所述第三子像素203共用一个所述第三发光层，且该所述第三发光层与四个所述第三电极重叠设置。
如图6a所示，图6a为图6中B-B’处的截面图，其中，ANO为第三子像素203的阳极，EL1为第三子像素203的电子传输层和电子注入层，EL2为空穴注入层和空穴传输层，CAT为第三子像素203的阴极，EML为发光层，ST为开关控制单元，DT为驱动单元，GI为栅极绝缘层，PL为平坦层，ENC为封装层；通过图6可以看出，相互靠近的第三子像素可以共用同一发光层（图6a显示共用一个发光层），但是两第三子像素203的阳极互相独立（即由两个驱动单元各自驱动），能够降低了制备过程中光罩的开口难度。
可以理解的是，通过将第三子像素203设置于虚拟矩形靠近所述公共侧边300一侧的两顶角，多个发光重复单元在基板上排列后，多个重复单元位于该顶角处的多个第三子像素203互相靠近，进一步增大了像素的开口率，降低了该像素光罩的制备难度，同时能有效防止混色问题的发生，提高了产品的生产良率。
本实施例中，一所述虚拟矩形内，所述第二子像素202的数量与所述第三子像素203的数量相同。
可以理解的是，将所述第二子像素202的数量设置的与所述第三子像素203的数量相同，提高像素单元的显示均匀度，同时可以使得空间利用率最大化，提高显示面板10的PPI。
本实施例中，如图4所示，所述第二发光层与至少两个相邻设置的所述第二电极重叠设置，所述发光单元组101内的至少一所述第二子像素202靠近所述公共侧边300设置，相邻两所述发光单元组101包括至少部分相邻接的两所述第二子像素202，相邻接的两所述第二子像素202具有一第二公共边，所述第二公共边与所述虚拟矩形的所述公共侧边300重合。
可以理解的是，采用该技术方案能够进一步的降低光罩的开口精细度，相邻的两第二子像素202可以共用一个发光层，降低制备难度，进而降低生产成本。
本实施例中，两相邻的所述发光单元组101关于所述公共侧边300对称设置。
可以理解的是，通过将两个发光单元组101对称设置，将两个虚拟矩形内的子像素关于所述公共侧边300对称设置，能够使得所述重复发光单元的图案更齐整，降低因发光间距不一致导致的明暗线变化，提高显示的均匀度。
本实施例中，所述第一子像素201的面积大于所述第二子像素202的面积，且所述第一子像素201的面积大于所述第三子像素203的面积。
可以理解的是，通过该设置方式，档三种颜色的像素因自身材料导致寿命不均时，可以将寿命短的像素设置为第一子像素201，通过增大第一子像素201的开口面积，进而延长该寿命短的像素的使用寿命，使得显示面板10的使用寿命能够进一步延长；例如，目前在RGB三色中受限于材料问题，蓝色像素的寿命最短，因此将蓝色像素的开口面积增大，RGB面积开口比例会根据显示设备的状况需要进行平衡分配，能够有效延长显示设备的使用寿命。
本实施例中，所述第一子像素201、第二子像素202、第三子像素203为红色子像素、绿色子像素、蓝色子像素的任意一种组合；
具体地，所示第一子像素201可以为蓝色子像素，第二子像素202可以为绿色子像素，第三子像素203可以为红色子像素；
具体地，如图7~8所示，所述第一子像素201的形状可以为圆形、三角形、矩形和正多边形中的一种；
第二子像素202的形状可以为扇形、三角形、矩形和多边形中的一种；
第三子像素203的形状可以为扇形、三角形、矩形和多边形中的一种；
具体地，所述虚拟矩形内，各所述第一子像素201的面积相同，且各所述第一子像素201的形状一致；和/或
各所述第二子像素202的面积相同，且各所述第二子像素202的形状一致；和/或
各所述第三子像素203的面积相同，且各所述第三子像素203的形状一致。
本申请还提供一种移动终端，包括上述任一实施例所述的显示面板10及终端主体，所述终端主体与所述显示面板10组合为一体。
综上，本申请通过在显示面板10内设置多个发光重复单元，每个发光重复单元包括两相邻设置的发光单元组101，每一发光单元组101包括一第一子像素201、至少一第二子像素202和至少两第三子像素203，其中，在发光单元组101内，至少两所述第三子像素203的第三电极通过第一导线电连接，使得一个发光单元组101不需要借助相邻结构的子像素就能够实现白光显示，有效提升了显示面板10的显示效果，使得显示面板10的显示色彩更加丰富，同时，在单一的发光单元组101内通过第一导线串连至少两个第三电极，使得发光单元组101内的第三像素能够同步驱动，降低显示异常的风险，提升器件性能；两个相邻的发光单元组101包括至少两个相邻的第三子像素203，相邻的两第三子像素203对应的两第三电极与一第三发光层重叠，使得本申请的结构在实现全彩显示的同时，相同颜色的子像素可以共用一个光罩开口，降低了光罩的设计与生产难度，提高生产效率。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
