在HSD的架构设计中,显示面板10会有垂直亮暗线的问题。垂直亮暗线是因为数据线110正极性到负极性转换，因为存在RC Delay,在转换过程时,尚未到达该有的电位,造成像素130偏暗,而像素130结构的设计中，正负极性转换的都在奇数列,所以造成垂直亮暗线。
下面参考附图和可选的实施例对本申请作说明。
如图1所示，在一实施例中公布了一种显示面板10，所述显示面板10包括：基板100、 多条设置在基板100上的数据线110、多条设置在基板100上的扫描线120、多个分别与对应的所述数据线110和扫描线120连接的像素130、输出栅极启动信号到所述扫描线120上打开所述像素130栅极驱动140、输出数据驱动信号到所述数据线110上，给所述像素130充电的源极驱动150；
每一行所述像素130包括多个像素组131，每个所述像素组131包括相邻的第一列像素132和第二列像素133，所述第一列像素132和第二列像素133与同一数据线110连接；所述第一列像素132与第2n-1行扫描线120连接，所述第二列像素133与第2n行扫描线120连接；
所述栅极驱动140在打开第2n-1行扫描线120的时候，所述源极驱动150通过对应数据线110给与第2n-1行扫描线120连接的第一列像素132充电，在打开第2n行扫描线120的时候，所述源极驱动150通过对应数据线110给与第2n行扫描线120连接的第二列像素133充电；
在一个显示周期内，所述源极驱动150输出极性相反的数据驱动信号，分别给连接在同一条数据线110上同一个像素组131内的第一列像素132和第二列像素133；
对同一个数据线110连接的下一个像素组131的第一列像素132，所述源极驱动150输出的数据驱动信号与上一个像素组131的第一列像素132极性相反。
所述源极驱动150输出驱动电压给每一列像素130，其中对于同一个灰阶值，至少有一列的第一列像素132对应的驱动电压小于第二列像素133对应的驱动电压；
所述n为等于或大于1的自然数，所述一个显示周期是一帧。
在使用半源极驱动150(Half source driving，HSD)架构设计的显示面板10中，第一列像素132和第二列像素133连接至同一条数据线110，连接在同一条数据线110上同一个像素组131内的第一列像素132和第二列像素133的数据驱动信号的极性相反，且下一个像素组131内的第一列像素132的数据驱动信号的极性和上一个像素组131内的第一列像素132的数据驱动信号的极性相反；同一个像素组131内，当数据线110充电对象从第一列像素132转换到第二列像素133时，要进行极性反转，由于电阻电容延迟(Resistance resistance delay，RC delay)，在扫描线120的打开时间周期内，第二列像素133充电后的实际像素130电压不能达到驱动电压，显示较暗，第二列像素133整体呈现一条亮线；而当数据线110充电对象从第二列像素组131向下一个像素组131内的第一列像素132转换时，极性相同，不需要进行极性反转，RC delay现象不明显，在扫描线120的打开时间周期内，第一列像素132充电后的实际像素130电压相对可以更接近或达到驱动电压，显示较亮，第一列像素132整体呈现一条亮线，在整个显示面板10中呈现出来的就是呈竖直的亮暗线，影响显示面板10的显示效果。
本方案中，源极驱动150输出驱动电压给每一列像素130，其中对于同一个灰阶值，至少有一列的第一列像素132对应的驱动电压小于第二列像素133对应的驱动电压，充电后，使得第一列像素132的实际像素130电压接近第二列像素133的实际像素130电压，第一列像素132显示亮度变暗，与第二列像素133的显示亮度差异减小，从而使得竖直亮暗线没有那么明显，减小竖直亮暗线的影响，提升显示面板10的显示效果。
如图1至图11所示，在一实施例中公开了一种上述显示面板10的驱动方法，包括步骤：
S11:在2n-1行扫描线120接收栅启动信号时，所述源极驱动150输出驱动电压为第一列像素132充电；
S12:在第2n行扫描线120接收栅启动信号时，所述源极驱动150输出驱动电压为第二列像素133充电；
其中对于同一个灰阶值，至少有一列的第一列像素132对应的驱动电压小于第二列像素133对应的驱动电压；
所述n为等于或大于1的自然数。
本方案中，将至少有一列的第一列像素132对应的驱动电压小于第二列像素133对应的驱动电压，使得至少有一列的第一列像素132的显示亮度变暗，与第二列像素133的显示亮度差异减小，亮线的亮度降低，从而使得竖直亮暗线没有那么明显，减小竖直亮暗线的影响，提升显示面板10的显示效果。
在一实施例中，如图4、图5和图9所示，连接在第2m-3列数据线110上的第一列像素132为蓝色，第二列像素133为绿色；连接在第m列数据线110上的第一列像素132为红色，第二列像素133为蓝色；连接在第2m-1列数据线110上的第一列像素132为绿色，第二列像素133为红色；所述驱动方法步骤包括：
S21:在所述2n-1行扫描线120接收栅启动信号前，对显示面板10显示的画面侦测；
S22:在侦测到第2m-1列数据线110上的第二列像素133和第m列数据线110上的第一列像素132关闭时，所述源极驱动150输出驱动电压为第2m-1列数据线110对应的第一列像素132和第2m-3列数据线110对应的第二列像素133充电；
其中，输出给第2m-1列数据线110对应的第一列像素132的驱动电压V1小于输出给第2m-3列数据线110对应的第二列像素133的驱动电压V2。
所述m为大于或等于2的偶数列。
当第2m-1列数据线110上的第二列像素133和第m列数据线110上的第一列像素132关闭时，即就是画面不显示红色，只显示蓝、绿色的杀伤模式(Kill Pattern)。
连接在第2m-1列数据线110上的第一列像素132为绿色，显示为亮线，连接在第2m-3列数据线110上的第二列像素133为绿色，显示为暗线。
由于人眼对绿色最为敏感，在Kill Pattern模式下的画面中，竖直亮暗线较为明显，对显示效果的影响较大。
本方案中，输出给第2m-1列数据线110对应的第一列像素132的驱动电压小于输出给第2m-3列数据线110对应的第二列像素133，第一列像素132的充电效率下雨第二列像素133的充电效率，使得第一列像素132的显示亮度变暗，与连接在第2m-3列数据线110上的第二列像素133显示亮度差异减小，从而使得绿色的竖直亮暗线没有那么明显，可以较大程度减小竖直亮暗线的影响，显示面板10的显示效果提升更明显；同时不需要改变显示面板10原有的架构设计，充电电压的调整方便，容易实施，节省成本。
在一实施例中，如图6、图7和图10所示，连接在第2m-3列数据线110上的第一列像素132为蓝色，第二列像素133为绿色；连接在第m列数据线110上的第一列像素132为红色，第二列像素133为蓝色；连接在第2m-1列数据线110上的第一列像素132为绿色，第二列像素133为红色；所述驱动方法步骤包括：
S31:在所述2n-1行扫描线120接收栅启动信号前，对显示面板10显示的画面侦测；
S32:在侦测到第2m-1列数据线110上的第二列像素133和第m列数据线110上的第一列像素132关闭时，在扫描线120的打开时间周期内，所述源极驱动150输出驱动电压为第2m-1列数据线110对应的第一列像素132的充电；
其中，为第2m-1列数据线110对应的第一列像素132充电的时间内，在第一时间段T1内，输出给第2m-1列数据线110对应的第一列像素132的驱动电压等于输出给第2m-3列数据线110对应的第二列像素133的驱动电压；在第二时间段T2内，输出给第2m-1列数据线110对应的第一列像素132的驱动电压小于输出给第2m-3列数据线110对应的第二列像素133的驱动电压，
所述m为大于或等于2的偶数列。
本方案中，在扫描线120的打开时间周期内，只有第一时间段内给第一列像素132充电的驱动电压才等于给第二像素130充电的驱动电压，在第二时间段内小于给第二像素130充电的驱动电压，即是说缩短了给第一列像素132充较高驱动电压的时间，使得一列像素130充电后的实际像素130电压设为小于驱动电压，第一列像素132的显示亮度变暗，与连接在第2m-3列数据线110的第二列像素133的显示亮度差异减小，从而减小竖直亮暗线的影响，提升显示面板10的显示效果。
本方案通过缩短给第一列像素132充较高驱动电压的时间，让第一列像素132的显示亮度变暗，可以较大程度减小竖直亮暗线的影响，显示面板10的显示效果提升更明显；同时不需要改变显示面板10原有的架构设计，充电时间的调整方便，容易实施，节省成本。
当然，除了上述的方案，只要是能让亮线变暗的其他方案都是可以的。
在一实施例中，如图11所示，所述在2n-1行扫描线120接收栅启动信号时，所述源极驱动150输出驱动电压为第一列像素132充电的步骤中，还包括：
S111:所述源极驱动150输出驱动电压为第2m-3列数据线110的第一列像素132充电，其中输出给第2m-3列数据线110对应的第一列像素132的驱动电压小于输出给第2m-3列数据线110对应的第二列像素133。
所述在第2n行扫描线120接收栅启动信号时，所述源极驱动150输出驱动电压为第二列像素133充电的步骤中，还包括：

在降低连接在第2m-1列数据线110上的第一列像素132亮度的基础上，降低第2m-3列数据线110上第一列像素132和第m列数据线110上第二列像素133的显示亮度，减小与连接在第2m-3列数据线110上的第二列像素133显示亮度的亮度差异，减小Kill Pattern模式下整个显示面板10上的竖直亮暗线的影响，显示面板10的显示效果提升更明显。
在一实施例中，所述源极驱动150输出驱动电压给每一列像素130，其中对于同一个灰阶值，所有的第一列像素132对应的驱动电压小于第二列像素133对应的驱动电压。
所有的第一列像素132对应的驱动电压小于第二列像素133对应的驱动电压，使得显示面板10所有第一列像素132的显示亮度变暗，与第二列像素133的显示亮度差异减小，从而使得竖直亮暗线没有那么明显，减小整个显示面板10上的竖直亮暗线的影响，显示面板10的显示效果提升更明显。
在一实施例中，所述源极驱动150输出给连接在第2m-3列数据线110上的第2n-1个像素组131内的第一列像素132驱动电压为正7伏，给第二列像素133动电压为负7伏；

输出给连接在第m列数据线110上的第2n个像素组131内的第一列像素132驱动电压为负7伏，给第二列像素133驱动电压为0伏。
当然，第一列像素132驱动电压和第二列像素133驱动电压也可以是其他可行的电压。
