下面参考附图和可选的实施例对本申请作进一步说明。
参考图1至图5所示，本申请实施例公布了一种显示面板200；所述显示面板200包括：第一基板；多个像素100，设置在所述第一基板上，所述像素包括第一像素110和第二像素120；多条数据线，设置在所述第一基板上；多条扫描线，设置在所述第一基板上；所述第一像素110和第二像素120连接于第n行数据线和第n行扫描线；所述第一像素110包括相邻设置的第一主像素111和第一辅像素113；所述第二像素120包括相邻设置的第二主像素121和第二辅像素123；所述第一主像素111和第一辅像素113连接于第n行扫描线和第n行数据线，所述第二主像素121和第二辅像素123连接于第n行扫描线和第n行数据线；所述第一辅像素113连接有拉低所述第一辅像素113充电电压的第一下拉电路115，所述第二辅像素123连接有拉低所述第二辅像素123充电电压的第二下拉电路125。
相对于图1和图2的像素架构来说，本申请的像素，包括第一像素110和第二像素120的架构，第一像素110和第二像素120连接于同一行数据线和同一行扫描线上；第一像素110分为第一主像素111和第一辅像素113，把第二像素120分为第二主像素121和第二辅像素123，该第一像素110包括充电电压不同的第一主像素111和第一辅像素113，该第二像素120包括充电电压不同的第二主像素121和第二辅像素123，如此使得同一行数据线和同一行扫描线打开的像素可以根据需要对应两个不同的电位，配合伽马电压进行色偏补偿，从而可以有效解决显示面板200特别是垂直取向面板(Vertical Alignment  Display，VA)模式的显示面板200的大视角色偏，甚至可以根据需要对应四个不同的电位，灵活的补偿亮暗不均匀和色偏的，使得显示面板200的显示效果非常好。
参考图5所示，在一实施例中，所述第一辅像素113包括第一辅像素电极114；第一下拉电路115包括第一放电开关T3和第一放电电容C1；所述第二辅像素123包括第二辅像素电极124；第二下拉电路125包括第二放电开关T6和第二放电电容C2；所述第一放电开关T3的控制端连接于第n+1行扫描线，源极端连接于所述第一辅像素电极114，漏极端连接于所述第一放电电容C1；所述第二放电开关T6的控制端连接于第n+1行扫描线，源极端连接于所述第二辅像素电极124，漏极端连接于所述第二放电电容C2。
本方案中，所述第一主像素111包括第一主像素电极112，所述第二主像素121包括第二主像素电极122；第一辅像素电极114通过第一放电电容C1放电，第二辅像素电极124通过第二放电电容C2放电；同一行扫描线通过第一放电开关T3和第二放电开关T6与第一辅像素电极114和第二辅像素电极124相连，使得同一行扫描线可以根据需要对应与第一主像素电极112电位不同的第一辅像素电极114，以及与第二主像素电极122电位不同的第二辅像素电极124，甚至该第一辅像素电极114和第二辅像素电极124也可以根据需要对应为不同电位，灵活的设置亮像素和暗像素，配合包括伽马电压在内的其他色偏补偿操作，可以有效解决显示面板200的大视角色偏；当然，不用第一放电开关T3和第二放电开关T6也可以，即不对放电电容的放电时间进行控制也是可以的，具体的，该第一辅像素包括第一辅像素电极；第一下拉电路包括第一放电电容；所述第二辅像素包括第二辅像素电极；第二下拉电路包括第二放电电容；该第一辅像素电极连接于所述第一放电电容；所述第一辅像素电极连接于所述第二 放电电容。但是对第一放电电容C1和第二放电电容C2的要求比较高，才能达到预设的亮暗差异；另外，该第一放电开关T3和第二放电开关T6的控制端可以连接于第n行扫描线，可以连接于第n+1行扫描线，还可以连接于其他行扫描线。
在一实施例中，所述第一基板包括公共电极线；所述第一辅像素电极114和公共电极线部分重叠形成所述第一放电电容C1；所述第二辅像素电极124和公共电极线部分重叠形成所述第二放电电容C2。
本方案中，可以利用第n行扫描线或者第n+1行扫描线或者其他行扫描线来控制第一放电电容C1和第二放电电容C2对第一辅像素电极114和第二辅像素电极124进行放电，使得第一像素110包括电位不同的第一主像素111和第一辅像素113，使得第二像素120包括电位不同的第二主像素121和第二辅像素123，基于此架构，有利于解决显示面板200的大视角色偏，达到更好的显示效果。
在一实施例中，所述第一放电电容C1的电容值与所述第二放电电容C2的电容值不同。本方案中，由于第一放电电容的电容值与所述第二放电电容C2的电容值不同，所以在受控于同一扫描线，并接收同一数据信号的情况下，该第一辅像素113和第二辅像素123的亮度不同，达到同一扫描线和同一数据信号下，使得包括第一像素110和第二像素120的像素电极可以包括至少三个不同的电压准位，相对于包括两种电压准位的像素，可以更灵活的设置亮像素和暗像素，有利于更好的解决显示面板200大视角色偏。并且，由于电压准位调节的更灵活性，我们可以基于同一数据信号，将其体现为不同的亮暗显示效果，如此变相的达到通过同一数据线和同一扫描线驱动两个不同像素的目的，即使得在扫描线和数据线不变的情况下，像素分辨率提升了一倍。
例如，第n行数据线接收到(200,200,200)灰阶亮度的数据信号，则使用本方案的架构，可以将第一像素110体现为对应(200,200,200)和(198,198,198)灰阶亮度的图像，而该第二像素120则可以体现为对应(200,200,200)和(195,195,195)灰阶亮度的图像，在设置适当的电容值并进行适当的信号处理基础上，可以在不改变数据线信号的情况下，将数据信号的分辨率加倍体现到显示效果中，达到变相的提升分辨率的作用。
在一实施例中，所述第一下拉电路115和第二下拉电路125的下拉效果不同。本方案中，由于第一下拉电路115和第二下拉电路125的下拉效果不同，所以在受控于同一扫描线，并接收同一数据信号的情况下，该第一辅像素113和第二辅像素123的亮度不同，达到同一扫描线和同一数据信号下，第一像素110和第二像素120的亮度不同，故而得以在扫描线和数据线不变的情况下，像素分辨率提升了一倍，在不改变数据信号的情况下，本方案的像素结构使得同一图像的分辨率由A分辨率，提升了一倍到2A分辨率；特别的，在观看低分辨率的图像时，使用本方案的显示面板200，可以看得更清楚。本方案不仅改善了大视角的色偏，而且，在相同的分辨率情况下，本方案单行的扫描时间增大了，故而充电时间也加长了，并且节约了显示面板200的制造成本。两侧像素亮度不同，每测像素还分别包括亮度不同的主、辅像素，起到了更进一步的改善色偏的效果；且提升了显示面板200的设计空间和对显示面板200设计的自由度。
在一实施例中，所述第一主像素包括第一主像素电极，所述第二主像素包括第二主像素电极；所述第一辅像素包括第一辅像素电极，所述第二辅像素包括第二辅像素电极；所述第一主像素电极112和第二主像素电极122的图案不同；所述第一辅像素电极114和第二辅像素电极124的图案不同。
本方案中，第一主像素电极112和第二主像素电极122的图案不同，第一辅像素电极114和第二辅像素电极124的图案不同，可以设置不同的畴，该第一辅像素电极114和第二辅像素电极124的开口率可以一样也可以不一样；在受控于同一扫描线，并接收同一数据信号的情况下，第一主像素111、第二主像素121、第一辅像素113和第二辅像素123的电压不同，亮度不同，进一步改善了显示面板200的色偏，提升了显示面板200的设计空间和设计的自由度，且单行的扫描时间增大，充电时间增长；第一主像素电极112和第二主像素电极122也可以是通过不同的材质形成，或者通过不同的制程形成，使得第一主像素电极112和第二主像素电极122的开口率不一样。
在一实施例中，所述第一主像素111包括第一主开关T1，所述第一辅像素113包括第一辅开关T2，所述第二主像素121包括第二主开关T4，所述第二辅像素123包括第二辅开关T5；所述第一主开关T1和第二主开关T4的漏电流不同；所述第一辅开关T2和第二辅开关T5的漏电流不同。
本方案中，第一主开关T1和第二主开关T4的漏电流不同，使得第一主像素111和第二主像素121的最终达到的充电电压不同，且在不影响显示面板200开口率的情况下，第一主像素111和第二主像素121的亮度不同；第一辅开关T2和第二辅开关T5的漏电流不同，使得第一辅像素113和第二辅像素123的最终达到的充电电压不同，且在不影响显示面板200开口率的情况下，第一辅像素113和第二辅像素123的亮度不同，如此，在同一行数据线和同一行扫描线控制下，该像素可以包括四个电位不同的像素电极，基于如此灵活的亮像素和暗像素的设置，有利于改善了显示面板200的色偏，且提升了显示面板200的设计空间和设计的自由度，增加了显示面板200的单行扫描时间，使得像素的充电时间增长。
在一实施例中，所述第一辅像素113包括第一辅像素电极114；所述第二辅像素123包括第二辅像素电极124；所述第一下拉电路115包括第一下拉电阻，所述第二下拉电路125包括阻值与所述第一下拉电阻不同的第二下拉电阻；所述第一下拉电阻的一端连接于所述第一辅像素电极114，另一端连接于公共电极线或第n+1行扫描线；所述第二下拉电阻的一端连接于所述第二辅像素电极124，另一端连接于公共电极线或第n+1行扫描线。
本方案中，采用第一下拉电阻和第二下拉电阻来使得下拉效果不同，电阻比较便宜，且方便在实际操作过程中的制作；第一下拉电阻和第二下拉电阻的阻值不同，可以使得第一辅像素电极114和第二辅像素电极124达到不同的充电亮度；在本方案中也可以是第一下拉电阻的一端连接于第一辅像素电极114，另一端连接于公共电极线或其他行扫描线；第二下拉电阻的一端连接于第二辅像素电极124，另一端连接于公共电极线或其他行扫描线。
另外，电阻阻值越大，对应的开口率越小；对应的，阻值越大对辅像素电极亮度的下拉效果越明显，而开口率越小对辅像素电极亮度下拉的效果也越大，如此两者相辅相成，可以在电阻阻值差异较小的情况下，为开口率所辅助，达到亮度差异较大的效果。
作为本申请的另一实施例，参考图1至图5所示，公开了一种显示面板200，所述显示面板200包括：第一基板；设置在所述第一基板上的多个像素，所述像素包括第一像素110和第二像素120；设置在所述第一基板上的多条数据线；设置在所述第一基板上的多条扫描线；所述第一像素110和第二像素120连接于第n行数据线和第n行扫描线；所述第一像素110包括相邻设置的第一主像素111和第一辅像素113；所述第二像素120包括相邻设置的第二主像素121和第二辅像素123；所述第一主像素111包括第一主像素电极112和第一主开 关T1，所述第一主开关T1的控制端连接于第n行扫描线，源极端连接于第n行数据线，漏极端连接于第一主像素电极112；所述第二主像素121包括第二主像素电极122和第二主开关T4，所述第二主开关T4的控制端连接于第n行扫描线，源极端连接于第n行数据线，漏极端连接于第二主像素电极122；所述第一辅像素113包括第一辅像素电极114和第一辅开关T2，所述第一辅开关T2的控制端连接于第n行扫描线，源极端连接于第n行数据线，漏极端连接于第一辅像素电极114；所述第二辅像素123包括第二辅像素电极124和第二辅开关T5，所述第二辅开关T5的控制端连接于第n行扫描线，源极端连接于第n行数据线，漏极端连接于第一辅像素电极114；所述第一辅像素113包括第一放电开关T3和第一放电电容C1；所述第二辅像素123包括第二放电开关T6和第二放电电容C2；所述第一放电开关T3的控制端连接于第n+1行扫描线，源极端连接于所述第一辅像素电极114，漏极端连接于所述第一放电电容C1；所述第二放电开关T6的控制端连接于第n+1行扫描线，源极端连接于所述第二辅像素电极124，漏极端连接于所述第二放电电容C2。
