请参阅图1至图4，所述数据线包括第一子数据线104以及第二子数据线105，所述第一子像素102与第一子数据线104电连接，所述第二子像素103与第二子数据线105电连接，所述第一子数据线104与所述第二子数据线105在所述单元区101内交替设置；
所述第一子数据线104与所述第二子数据线105的极性相反。
请参阅图1至图4，图中，减号表示负极性，加号表示正极性。在一个所述显示周期内，所述第一子数据线104的极性以正极性、负极性、正极性、负极性的顺序切换；

例如，在一个所述显示周期内，当所述第一子像素102在一个所述显示周期内的第一帧至第四帧所承载的极性的变化依次为正极性、负极性、正极性、负极性时，所述第一子数据线104在所述第一帧至所述第四帧的极性切换同样为正极性、负极性、正极性、负极性。
同理，当所述第二子像素103在一个所述显示周期内的第一帧至第四帧所承载的极性的变化依次为负极性、正极性、负极性、正极性时，所述第二子数据线105在所述第一帧至所述第四帧的极性切换同样为负极性、正极性、负极性、正极性。
本实施例中，由于一个所述显示周期存在四帧的切换，且第一帧至第四帧的所述显示面板的显示画面的亮度均不相等，为避免出现闪烁现象，所述显示面板的显示画面的刷新频率大于或等于240赫兹。
请参阅图1至图4，所述单元区101内，相邻两列所述第一子像素102共用一条所述第一子数据线104，相邻两列所述第二子像素103共用一条所述第二子数据线105。
本实施例中，所述单元区101内，相邻两列所述子像素之间可以设置一条数据线。
例如，位于第二列所述子像素靠近第一列所述子像素的一侧的所述数据线可以为一条所述第二子数据线105，该条所述第二子数据线105与第一列中的所述第二子像素103以及第二列中的所述第二子像素103电连接；位于第二列所述子像素靠近第三列所述子像素的一侧的所述数据线可以为一条所述第一子数据线104，该条所述第一子数据线104与所述第二列中的所述第一子像素102以及所述第三列中的所述第一子像素102电连接。
通过相邻两列所述第一子像素102共用一条所述第一子数据线104，相邻两列所述第二子像素103共用一条所述第二子数据线105的设置，有利于减少显示面板中的数据线的数量，简化所述显示面板的结构。
同时，本申请的所述显示面板通过所述第一子数据线104控制所述第一子像素102的极性，所述第二子数据线105控制所述第二子像素103的极性，所述第一子数据线104与所述第二子数据线105的极性相反，使所述显示面板在行方向以及列方向上实现了单点反转，有利于降低显示画面的颗粒感，提高所述显示面板的显示品质。
本实施例中，任一所述子像素与相邻的两条所述数据线的耦合电容相等。
由于所述子像素内设置有像素电极层，该像素电极层上存在电压，因此任一所述子像素与所述数据线之间存在耦合电压，形成耦合电容。且所述子像素与距离该所述子像素越近的所述数据线之间产生的耦合电容越大。当所述子像素与相邻的两条所述数据线的耦合电容相等时，有利于避免所述显示面板产生垂直串扰的问题。
本实施例中，任一所述子像素与相邻的两条所述数据线的间距可以相同。
例如，位于第二列的任一所述子像素与位于第一列所述子像素以及第二列所述子像素之间的所述第二子数据线105的间距，和位于第二列的任一所述子像素与位于第二列所述子像素以及第三列所述子像素之间的所述第一子数据线104的间距相同。
当所述数据线的输入电压相等时，保持任一所述子像素与相邻两条所述数据线的间距相同，有利于保持所述子像素与相邻的两条所述数据线的耦合电容相等，从而避免所述显示面板产生垂直串扰。
此外，随着显示面板尺寸的增加，数据线和扫描线的长度随之延长，在所述数据线远离数据传输端的方向上阻抗增加，接收到的电压减小，接收信号产生延迟。
因此，沿所述数据线远离数据传输端的方向上，所述数据线的宽度可以逐渐增大；或者，沿所述数据线远离数据传输端的方向上，所述数据线的电阻率逐渐减小。
通过沿所述数据线远离数据传输端的方向上使所述数据线的宽度逐渐增大或电阻率逐渐减小，有利于减缓所述数据线在沿远离数据传输端的方向上阻抗的增加，改善信号传输效果。
同时，沿所述数据线远离数据传输端的方向上，所述子像素与相邻两条所述数据线的间距之间减小。
通过沿所述数据线远离数据传输端的方向上，所述子像素与相邻两条所述数据线的间距之间减小，有利于在沿所述数据线远离数据传输端的方向上，所述子像素与相邻两条所述数据线之间的耦合电容的不变，保证显示面板尺寸增大后的显示质量的维持。
本实施例中，所述显示面板还可以包括输出电路板，所述输出电路板包括至少两个输出端子。
所述输出端子可以包括第一子输出端子以及第二子输出端子，所述第一子输出端子可以与至少一条所述第一子数据线104电连接，所述第二子输出端子可以与至少一条所述第二子数据线105电连接。
例如，一个所述第一子输出端子可以与至少两条所述第一子数据线104电连接，一个所述第二子输出端子可以与至少两条所述第二子数据线105电连接。
