背景技术

目前，为了提高显示面板的显示效果，大多采用相反的极性的电压驱动像素点的发光。但是，不同的极性的像素电极电压会同时对公共电极电压进行拉扯。当红、绿、蓝三种子像素相邻采用不同极性驱动时，绿色子像素对公共电极的极性耦合不能抵消红、蓝子像素对公共电极的极性耦合，导致绿色子像素的像素电极与公共电极之间的压差变大。尤其是在采用列反转驱动的显示画面中，相邻列的子像素采用不同极性驱动，人眼对绿色的敏感度大于红色和蓝色，各列绿色子像素均偏亮则因此会导致用户看到的画面整体偏绿。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请实施例的主要解决方案是，在显示面板中，显示面板包括显示阵列 1 ，所述显示阵列 1 包括沿行方向排列的像素组，各所述像素组包括沿所述行方向依次排列的第一像素列 11 、绿色像素列 12 和第三像素列 13 ，所述绿色像素列 12 包括多个沿列方向排列的绿色子像素 121 ，定义各所述绿色子像素 121 对应的驱动电压为第一电压；基于上述显示面板，通过获取所述第一像素列 11 的驱动电压的第一极性，获取所述绿色像素列 12 的驱动电压的第二极性；获取所述第三像素列 13 的驱动电压的第三极性；当所述第二极性与所述第一极性相反、且所述第二极性与所述第三极性相反时，获取所述显示面板的当前公共电压值和预设公共电压值；根据所述预设公共电压值和当前公共电压值确定各所述绿色子像素 121 对应的电压补偿值；根据各所述电压补偿值分别降低对应的第一电压。
由于采用列反转驱动的显示面板所显示的画面中，不同颜色的像素列采用不同极性驱动，由于各子像素的驱动电压与公共电压之间的极性耦合作用，会导致绿色子像素 121 的像素电压偏高，人眼对绿色的敏感度大于红色和蓝色，各列绿色子像素 121 均偏亮，偏亮的绿色范围较集中，则因此会导致用户看到的画面整体偏绿。

此外，本申请实施例还提出一种可读存储介质，所述可读存储介质上存储有 显示面板控制 程序，所述 显示面板控制 程序被处理器 2001 执行 以下实施例中显示面板控制方法的相关步骤的操作。
参照图 3 ，基于上述的显示面板，定义各所述绿色子像素 121 对应的驱动电压为第一电压。本申请实施例提供一种显示面板控制方法，所述显示面板控制方法包括：
步骤 S10 ，获取所述第一像素列 11 的驱动电压的第一极性，获取所述绿色像素列 12 的驱动电压的第二极性；获取所述第三像素列 13 的驱动电压的第三极性；
第一像素列 11 的驱动电压为驱动器（未图示）根据第一像素列 11 中每个第一子像素 111 对应的灰阶数据所生成的具有极性的驱动电压值；绿色像素列 12 的驱动电压为驱动器（未图示）根据第一像素列 11 中每个绿色子像素 121 对应的灰阶数据所生成的具有极性驱动电压值；第三像素列 13 的驱动电压为驱动器（未图示）根据第三像素列 13 中每个第三子像素 131 对应的灰阶数据所生成的具有极性驱动电压值。
第一极性、第二极性和第三极性具体包括正极性或负极性。第一极性、第二极性和第三极性可通过获取驱动器（未图示）的设置参数后提取，也可通过捕获驱动器（未图示）分别对应第一像素列 11 、绿色像素列 12 和第三像素列 13 的输出电压并进行极性检测等方式得到。
步骤 S20 ，当所述第二极性与所述第一极性相反、且所述第二极性与所述第三极性相反时，获取所述显示面板的当前公共电压值和预设公共电压值；
当绿色像素列 12 与第一像素列 11 、且与第三像素列 13 采用相反极性的驱动电压进行驱动时，表明当时的显示面板采用列反转的驱动方式进行驱动。例如，当第二极性为负极性，第一极性和第三极性均为正极性，此时，可获取显示面板的当前公共电压值和预设公共电压值。
具体的，当前公共电压值为侦测模块 2003 所检测的公共电极实际的电压值。预设公共电压值为公共电极的驱动电路理论上为公共电极分配的设定电压值。
步骤 S30 ，根据所述预设公共电压值和当前公共电压值确定各所述绿色子像素 121 对应的电压补偿值；
电压补偿值为对绿色子像素 121 对应的驱动电压进行负补偿的电压调整幅度值。
每个绿色子像素 121 对应的电压补偿值可相同，可根据预设公共电压值和当前公共电压值之间的公共电压差确定。具体的，在步骤 S10 前可预先建立多个公共电压差与电压补偿值之间的对应关系，并根据对应关系生成电压补偿值查找表并储存在存储器 2002 中形成预存电压补偿值查找表。需要说明的是，预存补偿值查找表中的预存电压补偿值，是基于其对应的公共电压差及不同补偿电压对公共电压的耦合效应进行确定的。具体的，可先将不同的公共电压差作为绿色子像素的驱动电压并测得对应的公共电压偏移值，公共电压差对应的电压补偿值可根据公共电压差及其对应公共电压偏移值确定，以保证电压补偿值的准确性。步骤 S30 可具体包括：确定所述预设公共电压值和当前公共电压值之间的公共电压差；根据所述公共电压差查询预存电压补偿值查找表，确定各所述绿色子像素的电压补偿值。其中，公共电压差的绝对值相同，对应的电压补偿值相同。在预存电压补偿值查找表中，查询与公共电压差一致的预存公共电压差，将查找表中与该预存公共电压差对应的预存电压补偿值作为当前绿色子像素的驱动电压的电压补偿值。
此外，由于每个绿色子像素 121 对应的驱动电压不同，对公共电极的极性耦合作用不同，因此，为了所确定的电压补偿值更加的准确，每个绿色子像素 121 对应的电压补偿值可不同。具体的，可根据所述第一电压、所述预设公共电压值和当前公共电压值，确定各所述绿色子像素 121 对应的电压补偿值。
步骤 S40 ，根据各所述电压补偿值分别降低对应的第一电压。
显示面板控制装置 3 将各电压补偿值发送至驱动器（未图示），驱动器（未图示）按照电压补偿值分别对应降低输出至各绿色子像素 121 的第一电压。
本申请实施例提出的一种显示面板控制方法，通过在依次排列的第一像素列 11 、绿色像素列 12 和第三像素列 13 的显示面板中，当显示面板采用列反转的方式进行驱动时，绿色像素列 12 与第一像素列 11 、第三像素列 13 对应的驱动电压的极性不同，根据当前公共电压值和预设公共电压值确定相应的电压补偿值，并按照电压补偿值降低各绿色子像素 121 对应的驱动电压，避免由于第一像素列 11 和第三像素列 13 对公共电极产生的极性耦合使绿色像素列 12 对应的像素电压过大，避免画面显示时出现偏绿现象，从而提高的显示画面的显示效果。
进一步的，基于上述图 3 所示的实施例，当所述第二极性与所述第一极性相反、且所述第二极性与所述第三极性相反时，所述获取所述显示面板的当前公共电压值和预设公共电压值的步骤之前，还包括：实时获取当前显示图像帧的图像灰阶；当所述图像灰阶小于或等于预设值时，执行所述获取所述显示面板的当前公共电压值和预设公共电压值的步骤。
这里当前显示图像帧的图像灰阶为根据显示图像帧中各个子像素所对应的像素灰阶计算得到的表征当前显示图像帧整体亮度的灰阶值。
当第二极性与第一极性、第三极性相反时，获取当前显示图像帧的图像灰阶。判断所获取的图像灰阶是否小于或等于预设值。在图像灰阶小于或等于预设值时，表明当前的显示图像帧为低灰阶图像，此时可获取所述显示面板的当前公共电压值和预设公共电压值，依次执行步骤 S30 、步骤 S40 对绿色子像素 121 对应的驱动电压进行调整。
在本实施例中，由于在高灰阶图像中，显示画面的整体亮度较大，绿色像素列 12 即使偏亮也较不容易被肉眼察觉。而在低灰阶图像中，显示图像的整体亮度较低，极性耦合使公共电压偏移使绿色像素列 12 偏亮在低灰阶图像中便显得尤其的明显，在低灰阶图像中人眼更容易察觉到显示列反转驱动的显示图像的偏绿。因此，通过上述方式，可有利于保证低灰阶图像显示时不会出现偏绿现象，提高显示面板的画面显示质量。
进一步的，基于上述的实施例，参照图 4 ，所述根据所述第一电压、所述预设公共电压值和当前公共电压值，确定各所述绿色子像素 121 对应的电压补偿值的步骤包括：
步骤 S31 ，根据所述预设公共电压值和所述当前公共电压值，确定各所述绿色子像素 121 的补偿基准值；
具体的，确定所述预设公共电压值与当前公共电压值之间的电压差，根据所确定的电压差确定所述补偿基准值。需要说明是，电压差的绝对值相同，对应的补偿基准值相同。例如，可将预设公共电压值和当前公共电压值的电压差直接作为各所述绿色子像素 121 的补偿基准值；也可得到预设公共电压值和当前公共电压值的电压差后，根据所得到的电压差和预设调整系数计算各绿色子像素 121 对应的补偿基准值等。需要说明的是，这里的补偿基准值为绿色子像素的驱动电压的调整幅度的基准值，为大于 0 的值。
步骤 S32 ，根据各所述第一电压确定各所述绿色子像素 121 对应的补偿修正值；
不同的第一电压可对应不同的绿色子像素 121 的补偿修正值。具体的，可将第一电压划分为若干个电压区间，不同的电压区间对应设有不同的绿色子像素 121 的补偿修正值，通过确定各个绿色子像素 121 的第一电压所在的电压区间，根据所确定的电压区间便可确定各个绿色子像素 121 对应的补偿修正值。
此外，也可建立第一电压和对应的补偿修正值之间的预设关系式，根据各个绿色子像素 121 的第一电压和预设关系式，计算得到各个绿色子像素 121 对应的补偿修正值。需要说明的是，这里的补偿修正值为绿色子像素的驱动电压的调整幅度的修正值，为大于 0 的值。
步骤 S33 ，根据所述补偿基准值和各所述补偿修正值，分别确定各所述绿色子像素 121 对应的电压补偿值。
将各绿色子像素 121 对应的补偿基准值与补偿修正值的差值，作为各绿色子像素 121 对应的电压补偿值。具体的，第一电压越大，其对应的补偿修正值可越大。也就是说，第一电压越大，对应的电压补偿值可越小。
在本实施例中，由于第一电压越大，其受到公共电极的极性耦合作用的影响便会越小，因此可结合第一电压、当前公共电压值和预设公共电压值来去确定各绿色子像素 121 对应的电压补偿值，使电压补偿值可适应于不同的第一电压适应性调整，有利于避免画面偏绿的同时保证显示画面所需的显示效果。
进一步的，所述第一像素列 11 包括多个沿列方向排列的第一子像素 111 ，所述第三像素列 13 包括多个沿列方向排列的第三子像素 131 ；定义所述绿色子像素 121 相邻的第一子像素 111 对应的驱动电压为第二电压，定义所述绿色子像素 121 相邻的第三子像素 131 对应的驱动电压为第三电压；基于上述图 4 的实施例，所述根据各所述第一电压确定各所述绿色子像素 121 对应的补偿修正值的步骤包括：
步骤 S330 ，根据各所述第一电压及其对应的第二电压、第三电压，确定各所述绿色子像素 121 对应的补偿修正值。
具体的，参照图 5 ，所述步骤 S330 包括以下步骤：
步骤 S331 ，确定各所述第一电压与其对应的第二电压之间的第一电压差，确定各所述第一电压与其对应的第三电压之间的第二电压差；
步骤 S332 ，根据各所述第一电压对应的第一电压差和第二电压差，确定各所述绿色子像素 121 对应的补偿修正值。
具体的，可建立第一电压差、第二电压差和相应的补偿修正值之间的对应关系，该对应关系可具体为公式、表格等。通过建立预设公式，依据第一电压差、第二电压差可计算得到各绿色子像素 121 相应的补偿修正值。也可将第一电压差作为补偿修正值查找表中的行、第二电压差作为补偿修正值查找表中的列，第一电压差与第二电压差所对应的预设补偿修正值作为表格中的数值，在确定第一电压差、第二电压差后，可通过查询补偿修正值查找表得到的预设补偿修正值作为相应的绿色子像素 121 对应的补偿修正值。需要说明是，若第一电压差和第二电压差的绝对值均相同，对应的补偿修正值相同。
此外，也可根据为第一电压差对应设置第一预设权重，为第二电压差对应设置第二预设权重，根据第一电压差及其对应的第一预设权重、第二电压差及其对应的第二预设权重通过加权平均计算得到综合差。不同的综合差可对应设置有不同的补偿修正值。通过计算综合差，便可得到各绿色子像素 121 对应的补偿修正值。具体的，可将综合差划分若干个差值区间，不同的差值区间对应不同的补偿修正值
其中，第一电压差和第二电压差越大，相应的补偿修正值越小。反之，第一电压差和第二电压差越小，相应的补偿修正值越大。
除了上述步骤 S331 、步骤 S332 外，还可直接建立第一电压、第二电压、第三电压及其对应的补偿修正值之间的对应关系。例如，补偿修正值 V 0 =xV 1 +yV 2 +zV 3 ，其中，定义 V 1 为第一电压， V 2 为第二电压， V 3 为第三电压， x 、 y 、 z 为预设系数，通过上述公式直接计算得到各绿色子像素 121 对应的补偿修正值。
在本实施例中，由于人眼所看到的绿色子像素 121 是否偏亮受到其相邻的子像素的亮度影响，若相邻子像素的亮度较大，则不容易察觉偏绿，若相邻子像素的亮度偏小，则容易察觉偏绿。为了使各绿色子像素 121 对应的驱动电压的调整更加的准确，因此，结合上述的第一电压、第二电压和第三电压确定各绿色子像素 121 对应的补偿修正值，可准确的调节各绿色子像素 121 相应的驱动电压，有利于避免画面偏绿的同时进一步提高显示画面的显示质量。
其中，第一电压差和第二电压差可表征绿色子像素 121 与其相邻的第一子像素 111 、第三子像素 131 之间的亮度的相对差异，当相对差异较大时，人眼越容易察觉偏绿现象，相应的补偿修正值越小，以使电压补偿值越大且越接近补偿基准值，以保证显示画面不会出现偏绿现象。当相对差异较小时，人眼越不容易察觉偏绿现象，相应的补偿修正值越大，以使电压补偿值越小，可保证显示画面不会出现偏绿现象的同时保证所显示的画面可越接近当前图像帧所需的显示效果。
进一步的，所述显示面板还包括驱动器（未图示），所述驱动器（未图示）设置为根据各所述第一电压对应驱动各所述绿色子像素 121 ，基于上述实施例，参照图 6 ，所述根据所述预设公共电压值和当前公共电压值确定各所述绿色子像素 121 对应的电压补偿值的步骤包括：
步骤 301 ，获取所述驱动器（未图示）输出至各所述绿色子像素 121 的当前电压，并定义为第四电压；获取各所述绿色子像素 121 对应的目标像素电压；
第四电压为驱动器（未图示）输出至各绿色子像素 121 的实际电压值。这里的目标像素电压为根据当前图像帧的图像数据所确定的各绿色子像素 121 对应的像素电压的理论值。显示面板控制装置 3 根据当前图像帧的图像数据确定各绿色子像素 121 对应的目标像素电压后，可根据各绿色子像素 121 对应的目标像素电压和预设公共电压值，确定各绿色子像素 121 对应的驱动电压（即上述的第一电压）。
步骤 302 ，根据所述当前公共电压和各所述第四电压确定各所述各所述绿色子像素 121 的当前像素电压；
步骤 303 ，根据所述预设公共电压值和当前公共电压值确定各所述绿色子像素 121 对应的第一补偿值；根据各绿色子像素 121 的目标像素电压和当前像素电压的差值，确定各所述绿色子像素 121 对应的第二补偿值；
将依照上述实施例中的根据预设公共电压值和当前公共电压值所确定的电压补偿值作为第一补偿值。
由于数据线的损耗或相邻数据线之间的电压耦合，会导致驱动器（未图示）实际输出至绿色子像素 121 的第四电压和第一电压会有所偏差，此外，由于公共电压也发生极性偏移，因此各绿色子像素 121 的当前像素电压和目标像素电压之间会存在差异导致像素电压的失真。因此，不同的目标像素电压和当前像素电压的差值，可对应设置有不同的驱动电压的第二补偿值，以降低像素电压失真对显示画面效果的影响。
步骤 304 ，根据各所述第一补偿值与其对应的第二补偿值，确定各所述绿色子像素 121 对应的电压补偿值。
具体的，可将各绿色子像素 121 对应的第一补偿值和第二补偿值的和作为该绿色子像素 121 对应的电压补偿值。
在本实施例中，通过上述方式确定各绿色子像素 121 对应的电压补偿值，有利于避免图像偏绿的同时减少信号失真对显示画面的影响，从而进一步提高显示画面的显示效果。
