 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
本发明针对现有技术的阵列基板及显示面板，当通过喷墨打印工艺制备像素结构时，无法同时保证子像素发光均匀度和像素开口率，本实施例能够解决该缺陷。
如图1所示，本发明实施例提供的阵列基板，包括显示区100a和非显示区100b，所述显示区100a内设置有像素结构，用于发光显示；所述非显示区100b设置有驱动电路，用于驱动所述像素结构中的像素单元发光。
如图2所示，所述像素结构包括多条扫描线10和多条数据线20，多条扫描线10和多条数据线20交叉限定出多个像素单元，每一所述像素单元包括两两相互对接且呈蜂窝状排列的第一子像素1、第二子像素2以及第三子像素3，其中，所述第一子像素1、所述第二子像素2以及所述第三子像素3的形状均为正六边形均采用正六边形设计，一方面，由于正六边形的内角均为钝角，且正六边形的中心至各个顶点的距离相等，因此采用本发明实施例提供的像素结构，当进行喷墨打印时，墨滴能够在子像素内部实现均匀铺展，铺展性较好；另一方面，由于正六边形的各内角为120°，故能够使得各子像素之间排列紧密，从而提高像素开口率；以所述像素结构中的一个像素单元为例，如图3所示，所述第一子像素1和所述第二子像素2之间通过连接边12相连接，所述第二子像素2和所述第三子像素3之间通过连接边23相连接。
在本发明实施例中，所述第一子像素1、所述第二子像素2以及所述第三子像素3分别为红色子像素R、蓝色子像素B1和绿色子像素G，且每列子像素均显示为同一种颜色。
进一步地，由于采用喷墨打印工艺打印制得的蓝色子像素B1的发光效率以及发光寿命均较低，容易导致发光亮度不足而产生色偏，因此在上述提供的RGB像素结构的基础上，将单个像素单元增加至少一列蓝色子像素B2，蓝色子像素B1和蓝色子像素B2之间交替发光以延长蓝色子像素的寿命；具体地，每一所述像素单元还包括第四子像素4，所述第四子像素4为蓝色子像素，所述第一子像素1、所述第二子像素2、所述第三子像素3以及所述第四子像素4之间呈蜂窝状排列。
在一种实施方式中，如图4所示，所述第四子像素4可以设置于所述第二子像素2和第三子像素3之间，即同一像素单元中的两列蓝色子像素相邻设置，所述像素单元采用RB1B2G的排列方式；同样地，以所述像素结构中的一个像素单元为例，如图5所示，所述第一子像素1和所述第二子像素2之间通过连接边12相连接，所述第二子像素2和所述第四子像素4之间通过连接边24相连接，所述第四子像4素和所述第三子像素3之间通过连接边43相连接。
在另一种实施方式中，如图6所示，所述第四子像素4还可以设置于所述第三子像素3和下一像素单元的第一子像素1之间，即同一像素单元中的两列蓝色子像素间隔设置，所述像素单元采用RB1GB2的排列方式；同样地，以所述像素结构中的一个像素单元为例，如图7所示，所述第一子像素1和所述第二子像素2之间通过连接边12相连接，所述第二子像素2和所述第三子像素3之间通过连接边23相连接，所述第三子像素3和所述第四子像素4之间通过连接边34相连接。
需要说明的是，本发明实施例是以在原有的RGB像素基础上增加一列蓝色子像素为例进行阐述说明的，然而本发明实施例不应以此为限，根据实际情况还可增加两列蓝色子像素、三列蓝色子像素……甚至更多列蓝色子像素。
继续参考图4、图5，以所述像素单元采用RB1GB2的排列方式为例，所述像素结构包括偶数行子像素和奇数行子像素，每一像素单元包括位于偶数行的第一子像素1、位于偶数行的第四子像素4以及位于奇数行的第二子像素2、位于奇数行的第三子像素3，每一子像素均包括横向边线和纵向边线，需要说明的是，横向边线平行于水平方向，纵向边线向竖直方向延伸；所述像素结构还包括多条信号走线，例如扫描线10和数据线20，在一种实施方式中，所述数据线20沿每列子像素纵向边线设置，所述数据线20呈折线状；所述扫描线10包括奇数行扫描线和偶数行扫描线，所述扫描线10沿每列子像素横向边线设置；在本发明实施例中，所述数据线20位于各列子像素的左侧，同一列子像素共用一根数据线20。
具体地，数据线Data-R控制所述第一子像素1的发光，数据线Data-B1控制所述第二子像素2的发光，数据线Data-B2控制所述第四子像素4的发光，数据线Data-G控制所述第三子像素3的发光；奇数行扫描线控制第二子像素2和第三子像素3的接通，偶数行扫描线控制第一子像素1和第四子像素4的接通；例如，以扫描线gate1和扫描线gate2控制的像素单元为例对像素单元的驱动方式进行简单说明，当扫描线gate1为高电平时，第二子像素2和第三子像素3中的薄膜晶体管的栅极打开，数据线Data-B1和数据线Data-G将数据信号分别传递给第二子像素2和第三子像素3中的薄膜晶体管的源极，从而实现第二子像2素和第三子像素3的发光；当扫描线gate2为高电平时，第一子像素1和第四子像素4中的薄膜晶体管的栅极打开，数据线Data-R和数据线Data-B2将数据信号分别传递给第一子像素1和第四子像素4中的薄膜晶体管的源极，从而实现第一子像素1和第四子像素4的发光，进而使得像素单元发光；或者数据线Data-B1和数据线Data-B2选择性打开，使得第二子像素2和第四子像素4实现交替性发光，即使得蓝色子像素B1和蓝色子像素B2交替性发光，从而可以延长蓝色子像素的寿命。
进一步地，继续参考图1，所述阵列基板包括栅极驱动器101和源极驱动器102，所述栅极驱动器101包括位于所述像素结构两侧的第一栅极驱动器1011和第二栅极驱动器1012，所述第一栅极驱动器1011用于提供扫描信号至所述奇数行扫描线，所述第二栅极驱动器1012用于提供扫描信号至所述偶数行扫描线，所述源极驱动器102用于提供数据信号至所述数据线20，故采用双栅极驱动器的方式，可以提高像素的发光效率。
当然，在其他实施方式中，如图8所示，所述数据线20与所述扫描线10的位置可以互换，也就是说，所述数据线20包括奇数行数据线和偶数行数据线，所述数据线20沿每列子像素横向边线设置；所述扫描线10沿每列子像素纵向边线设置，所述扫描线10呈折线状，所述扫描线10位于各列子像素的左侧，同一列子像素共用一根扫描线10。
同理，具体地，扫描线Gate-R控制所述第一子像素1的发光，扫描线Gate-B1控制所述第二子像素2的发光，扫描线Gate-B2控制所述第四子像素4的发光，扫描线Gate-G控制所述第三子像素3的发光；奇数行数据线控制第二子像素2和第三子像素3的接通，偶数行数据线控制第一子像素1和第四子像素4的接通；例如，以Data1和Data2控制的像素单元为例对像素单元的驱动方式进行简单说明，当扫描线Gate-R、扫描线Gate-B1、扫描线Gate-B2以及扫描线Gate-G为高电平时，各列第一子像素1、第二子像素2、第三子像素3以及第四子像素4中的薄膜晶体管的栅极均打开，当数据线Data1为高电平时，数据线Data1将数据信号分别传递给第二子像素2和第三子像素3中的薄膜晶体管的源极，从而实现第二子像素2和第三子像素3的发光；当数据线Data2为高电平时，数据线Data2将数据信号分别传递给第一子像素1和第四子像素4中的薄膜晶体管的源极，从而实现第一子像素1和第四子像素4的发光，进而使得像素单元发光；或者扫描线Gate-B1和扫描线Gate-B2选择性打开，使得第二子像素2和第四子像素4实现交替性发光，即使得蓝色子像素B1和蓝色子像素B2交替性发光，从而可以延长蓝色子像素的寿命。
进一步地，如图9所示，所述阵列基板包括显示区200a和非显示区200b，所述非显示区200b内设置有栅极驱动器202和源极驱动器201，所述源极驱动器201包括位于所述像素结构两侧的第一源极驱动器2011和第二源极驱动器2012，所述第一源极驱动器2011用于提供数据信号至所述奇数行数据线，所述第二源极驱动器2012用于提供数据信号至所述偶数行数据线，所述栅极驱动器202用于提供扫描信号至所述扫描线10，故采用双源极驱动器的方式，可以提高像素的发光效率。
本发明实施例还提供一种显示面板，所述显示面板包括上述阵列基板，所述显示面板可以为液晶显示面板。
有益效果为：本发明实施例提供的显示面板，通过将各子像素设计成等边六边形形状，各子像素拐角处为钝角120°，有利于喷墨打印制程中打印墨滴的铺展，使得子像素的发光均匀度得到显著提升；并且每一像素单元采用RB1B2G或RB1G2B排列组合的方式，双列蓝色子像素交替使用，可以平衡蓝色子像素寿命不佳的问题，有益于实现喷墨打印产品的量产化，满足高像素密度产品的需求。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
