本申请提供显示面板的控制方法，所述方法包括但不限于以下实施例以及以下实施例的组合。
在一实施例中，如图1所示，所述显示面板的控制方法包括但不限于以下步骤。
S1，获取显示面板中第一位置的第一实际亮度参数和第一参考亮度参数。
其中，所述显示面板可以为液晶显示面板或者有机发光二极管显示面板，可以理解的，所述显示面板中包括多个子像素，每一所述子像素具有对应的亮度，当向所述子像素加载对应的电压时，所述第一实际亮度参数和所述第一参考亮度参数可以分别表示位于所述第一位置处的所述子像素的实际亮度和理论亮度，进一步的，所述第一实际亮度参数和所述第一参考亮度参数也可以分别包括影响对应的所述子像素的实际亮度的至少一参数和影响对应的所述子像素的理论亮度的至少一参数，例如对应的电压值、充电时间等。
其中，当所述显示面板为液晶显示面板时，每一所述子像素对应的等效电路可以参考如图2所示的电路单元100，所述电路单元100由交叉排布的栅极线102和数据线103限定，所述电路单元100包括薄膜晶体管T、液晶电容Clc、存储电容Cst和公共电极Com，其中，所述薄膜晶体管T的栅极和源极分别电性连接所述栅极线102和所述数据线103，所述公共电极Com包括阵列基板公共电极和彩膜基板公共电极，所述薄膜晶体管的漏极分别和所述阵列基板公共电极、所述彩膜基板公共电极之间形成所述存储电容Cst和所述液晶电容Clc。需要注意的是，所述栅极线102和所述薄膜晶体管T的漏极之间存在耦合电容Cgs，因此当所述栅极线102中传递的电信号由高电压Vgh降低为低电压Vgl时，所述耦合电容Cgs两端的电压差无法突变，造成所述薄膜晶体管T的漏极中传递的电信号的电压值也会有所降低，也即所述薄膜晶体管T的漏极中传递的电信号的电压值Vs相比较所述薄膜晶体管T的源极中传递的电信号的电压值Vd会有所降低。
具体的，如图3所示，此处以所述显示面板中的其中一所述栅极线102的近端子像素B、所述栅极线102的远端子像素C以及与所述子像素C对应的所述数据线103的近端子像素A为例进行说明，如图4(a)、图4(b)和图4(c)分别表示子像素A、子像素B和子像素C处对应的若干电信号的波形图，Vg、Vd和Vs依次为所述栅极线102中传递的电信号、所述数据线103的中传递的电信号和所述薄膜晶体管T的漏极中传递的电信号，其中一帧的周期为T，可以认为所述周期T等于所述电信号Vg中相邻两个上升沿之间的时间间隔，此处针对一帧的周期T内进行讨论。可以理解的，在周期T内当所述栅极线102中传递的电信号Vg的电压值变为对应的高电压Vgh后，所述薄膜晶体管T的漏极中传递的电信号Vs理论上可以等于所述数据线103的中传递的电信号Vd。需要注意的是，如图4(b)和图4(c)所示，子像素B和子像素C中对应的所述数据线103的中传递的电信号Vd相当，由于子像素B、子像素C分别为所述栅极线102的近端子像素、远端子像素，即子像素B处的电信号Vg和子像素C处的电信号Vg的衰减、上升速度和下降速度不同，导致子像素C处的耦合电容Cgs和子像素B处的耦合电容Cgs不同，当所述栅极线102中传递的电信号Vg的电压值由对应的所述高电压Vgh变成对应的所述低电压Vgl时，子像素C处的电信号(Vd-Vs)和子像素B处的电信号(Vd-Vs)不同；如图4(a)和图4(c)所示，子像素C和子像素A中对应的所述栅极线102中传递的电信号Vg相当，由于子像素C、子像素A分别为所述数据线103的远端子像素、近端子像素，即子像素C处的电信号Vd和子像素A处的电信号Vd的衰减和上升速度不同，同理，当所述栅极线102中传递的电信号Vg的电压值由所述高电压Vgh变成所述低电压Vgl时，子像素C处的耦合电容Cgs和子像素A处的耦合电容Cgs不同，导致子像素C处的电信号(Vd-Vs)和子像素A处的电信号(Vd-Vs)不同。
进一步的，根据上文分析可知，每一所述数据线103的两端分别连接对应的数据信号源和对应的多个所述子像素，对于同一所述数据线103上的多个子像素而言，由于所述数据线103的电阻消耗等原因，多个所述子像素处的电信号Vg与对应的数据信号源的输出信号Vg1之间也存在差异。可以理解的，根据上文分析可知：对于每一所述子像素而言，对应的所述电信号Vs和对应的数据信号源的输出信号Vg1之间存在差异，且对应的所述电信号Vs和对应的所述电信号Vs之间也存在差异。
其中，所述第一位置可以为所述显示面板中的任一子像素所处位置，进一步的，所述第一位置可以为所述显示面板的中心位置或者为控制所述显示面板的中心位置的所述子像素的数据线所控制的最近端子像素。其中，所述第一实际亮度参数和所述第一参考亮度参数均为所述第一位置的所述子像素对应的所述电信号Vg由所述高电压Vgh变成所述低电压Vgl后，且所述电信号Vs稳定时期的参数。

S2，判断所述第一参考亮度参数与所述第一实际亮度参数的差值的绝对值是否小于第一阈值。
可以理解的，所述第一阈值可以根据所述显示面板的实际亮度差异进行设置，例如，可以将人眼目测的所述显示面板中所述第一位置处的子像素的亮度差异位于较小和较大之间的一个差异对应的绝对值作为所述第一阈值。其中，此处以所述第一实际亮度参数为位于所述第一位置的所述子像素的实际亮度值、所述第一参考亮度参数为位于所述第一位置的所述子像素的理论亮度值为例进行说明，具体的，当位于所述第一位置的所述子像素的实际亮度值和理论亮度值的差值的绝对值小于所述第一阈值时，可以不进行处理；否则，需要调整与位于所述第一位置的所述子像素相关的参数。
其中，当所述步骤S2的判断结果为否，即当所述第一参考亮度参数与所述第一实际亮度参数的差值的绝对值大于所述第一阈值时，可以至少执行以下步骤S3和步骤S4。
S3，根据所述第一参考亮度参数与所述第一实际亮度参数的差值，确定所述显示面板中所述第一位置的第一补偿亮度参数。
其中，此处还是以所述第一实际亮度参数为位于所述第一位置的所述子像素的实际亮度值、所述第一参考亮度参数为位于所述第一位置的所述子像素的理论亮度值为例进行说明，可以理解的，当位于所述第一位置的所述子像素的实际亮度值和理论亮度值的差值的绝对值大于所述第一阈值时，表示所述第一位置的所述子像素的实际亮度值和理论亮度值的差异较大，此时所述第一补偿亮度参数可以等于所述第一参考亮度参数与所述第一实际亮度参数的差值。
S4，根据所述第一补偿亮度参数和所述显示面板中所述第一位置的第一预设亮度参数，确定所述显示面板中所述第一位置的第一目标亮度参数。
需要注意的是，所述步骤S1至所述步骤S4可以执行于对所述显示面板进行测试期间，确定了所述第一目标亮度参数后可以控制所述显示面板进行画面显示。其中，可以对所述显示面板中的每一所述子像素进行所述步骤S1至所述步骤S3以获取每一所述子像素对应的所述第一补偿亮度参数之后再执行所述步骤S4，也可以对所述显示面板中位于所述第一位置的所述子像素进行所述步骤S1至所述步骤S4以控制所述第一位置的所述子像素的发光情况。
其中，所述第一预设亮度参数可以为所述显示面板进行画面显示期间时位于所述第一位置的所述子像素的理论亮度值或者与位于所述第一位置的所述子像素的理论亮度值相关的参数，此处以所述第一预设亮度参数为所述显示面板进行画面显示期间时位于所述第一位置的所述子像素的理论亮度值为例进行说明。可以理解的，此时所述第一位置的所述子像素的实际亮度值和理论亮度值的差异较大，即所述第一位置的所述子像素中与所述第一预设亮度参数对应的实际亮度值和理论亮度值的差异较大。其中，此处还是以所述第一实际亮度参数为位于所述第一位置的所述子像素的实际亮度值、所述第一参考亮度参数为位于所述第一位置的所述子像素的理论亮度值为例进行说明，此时所述第一目标亮度参数可以等于所述第一预设亮度参数和所述第一补偿亮度参数之差。
可以理解的，基于所述第一预设亮度参数，结合所述第一补偿亮度参数，可以计算出所述第一目标亮度参数，即此时位于所述第一位置的所述子像素中与所述第一目标亮度参数对应的实际亮度值，可以等于所述第一位置的所述子像素中与所述第一预设亮度参数对应的理论亮度值，本实施例可以实现所述显示面板中所述第一位置处的所述子像素显示为与所述第一预设亮度参数对应的理论亮度值。
进一步的，当所述显示面板为双极性的液晶显示面板时，每一所述子像素在相邻的两段时间内偏转的方向相反。例如当所述彩膜基板公共电极的电信号的电压值为0V时，若在相邻设置的第一时段和第二时段的极性分别为正性和负性，例如所述像素电极上的电压在第一时段和第二时段分别为(-4)V和8V，则所述液晶分子在所述第一时段和所述第一时段可以分别正偏α和反偏(-2*α)。可以理解的，此处以当所述彩膜基板公共电极的电信号的电压值为0V为例进行说明：当所述第一参考亮度参数与所述第一实际亮度参数的差值为正数时，则会增加正性偏转的液晶分子的偏转幅度，以及减负性偏转的液晶分子的偏转幅度，即所述第一参考亮度参数与所述第一实际亮度参数的差异性对正性偏转的液晶分子的偏转幅度和负性偏转的液晶分子的偏转幅度的影响不一致，会造成正性偏转与反性偏转的过渡期间出现画面闪烁。本实施例旨在通过所述第一补偿亮度参数控制对应的所述子像素的发光亮度可以为与所述第一预设数据电压对应的理论亮度值，以改善上述画面闪烁的现象。
在一实施例中，如图5和图6所示，所述步骤S1可以包括但不限于如下步骤：

具体的，如图2所示，所述薄膜晶体管T的漏极可以电性连接像素电极，即所述第一像素电压可以等于所述第一位置的所述子像素对应的所述电信号Vs稳定时的电压值，所述第一数据电压为此时连接于对应的所述数据线103的数据信号源输出的电信号的电压值。根据上文分析可知，由于所述电信号Vd的衰减和所述耦合电容Cgs的存在，所述第一像素电压会小于所述第一数据电压；可以理解的，所述第一像素电压可以理解为对应的所述薄膜晶体管T的漏极的实际电压值，其决定位于所述第一位置的所述子像素的实际亮度，所述第一数据电压可以理解为对应的所述薄膜晶体管T的漏极的理论电压值，其决定对应的所述第一位置的所述子像素的理论亮度，故此处可以将所述第一像素电压和所述第一数据电压分别作为所述第一实际亮度参数和所述第一参考亮度参数。
可以理解的，如图5和图6所示，基于所述步骤S101，所述步骤S2可以包括但不限于如下步骤：S201，判断所述第一数据电压与所述第一像素电压的差值的绝对值是否小于所述第一阈值；所述步骤S3包括但不限于如下步骤：S301，若否，根据所述第一数据电压与所述第一像素电压的差值，确定所述显示面板中所述第一位置的第一补偿亮度参数。其中，所述第一补偿亮度参数可以等于所述第一数据电压与所述第一像素电压的差值，例如当所述第一像素电压和所述第一数据电压分别为6V和8V时，所述第一补偿亮度参数为(-2)V。具体的，所述步骤S201和所述步骤S301可以分别参考上文中关于所述步骤S2和所述步骤S3的描述。

S402，根据所述第一补偿亮度参数和所述第一预设数据电压，确定所述显示面板中所述第一位置的第一目标数据电压。
其中，根据上文分析可知，所述第一补偿亮度参数可以等于所述第一数据电压与所述第一像素电压的差值，并且所述第一目标数据电压可以等于所述第一预设数据电压和所述第一补偿亮度参数之差，例如当所述第一预设数据电压为3V时，所述第一目标数据电压为5V。可以理解的，基于所述第一预设数据电压，结合所述第一补偿亮度参数，可以计算出所述第一目标数据电压，即此时所述第一位置的所述子像素中与所述第一目标数据电压对应的所述薄膜晶体管T的漏极的实际电压值，可以等于所述第一位置的所述子像素中与所述第一预设数据电压对应的所述薄膜晶体管T的漏极的理论电压值，本实施例可以实现所述显示面板中所述第一位置处的所述子像素显示为与所述第一预设数据电压对应的理论亮度值，并且可以改善双极性显示中的画面闪烁现象。
在一实施例中，如图6所示，基于所述步骤S101，所述步骤S4也可以包括但不限于如下步骤：
S403，获取所述显示面板中所述第一位置的第一公共电压。
具体的，根据上文分析可知，所述步骤S403以及后续步骤可以执行于所述显示面板进行测试期间，所述第一公共电压可以为所述显示面板进行画面显示期间时位于所述第一位置的所述子像素的对应的所述彩膜基板公共电极的电信号的电压值。需要注意的是，位于所述第一位置的液晶分子位于对应的所述像素电极和对应的所述彩膜基板公共电极之间，即所述第一像素电压和所述第一公共电压中的至少一者控制对应的所述液晶分子的偏转状态，以控制对应的所述子像素的发光情况。进一步的，所述显示面板中的所述彩膜基板公共电极可以整层设置，即每一所述子像素对应的所述彩膜基板公共电极的电信号的电压值均可以等于所述第一公共电压Vcom，例如图4(a)、4(b)和4(c)中子像素A、子像素B和子像素C三者对应的所述彩膜基板公共电极的电信号的电压值均可以等于所述第一公共电压Vcom。
S404，根据所述第一补偿亮度参数和所述第一公共电压，确定所述显示面板中所述第一位置的第一目标公共电压。
可以理解的，根据上文分析可知，此时所述第一位置的所述子像素的所述电信号Vs的实际值和所述电信号Vs的理论值的差异较大，此时所述第一补偿亮度参数可以等于所述第一数据电压与所述第一像素电压的差值，并且所述第一目标公共电压可以等于所述第一公共电压和所述第一补偿亮度参数之和，例如当所述第一公共电压和所述第一补偿亮度参数分别为0V和(-2)V时，所述第一目标公共电压为(-2)V。可以理解的，结合图4(a)，此处以子像素A处于所述第一位置为例进行说明，基于所述第一公共电压Vcom，结合所述第一补偿亮度参数，可以计算出所述第一目标公共电压Vcom'，结合上文分析可知，即此时所述第一位置的所述子像素中与所述第一目标公共电压Vcom'、所述第一预设数据电压对应的所述薄膜晶体管T的漏极的实际电压值，可以等于所述第一位置的所述子像素中与所述第一预设数据电压、所述第一公共电压Vcom对应的所述薄膜晶体管T的漏极的理论电压值。同理，结合图4(b)和图4(c)，子像素B、子像素C分别根据第二补偿亮度参数、第三补偿亮度参数，也具有对应的第二目标公共电压Vcom''、第三目标公共电压Vcom'''，其中所述第二补偿亮度参数的确定方式和所述第三补偿亮度参数的确定方式可以参考上文中关于所述第一补偿亮度参数的确定方式，所述第二目标公共电压Vcom''和所述第三目标公共电压Vcom'''的确定方式可以参考上文中关于所述第一目标公共电压Vcom'的确定方式。
进一步的，所步骤S404之后还可以包括：更新所述第一公共电压Vcom为所述第一目标公共电压Vcom'，本实施例可以通过调节位于所述第一位置的所述子像素对应的彩膜基板公共电极的电信号的电压值，以实现所述显示面板中所述第一位置处的所述子像素显示为与所述第一预设数据电压、所述第一公共电压对应的理论亮度值。
在一实施例中，如图6所示，所述步骤S404之后还可以包括但不限于以下步骤。
S405，获取所述第一目标公共电压与所述显示面板中第二位置的第二公共电压的差值作为第一差值。
可以理解的，在所述步骤S4中，通过所述步骤S403至所述步骤S404确定所述第一目标公共电压，即对于所述第一位置的所述子像素而言，可以通过更新所述第二公共电压为所述第一目标公共电压，以使位于所述第一位置的所述子像素显示为与所述第一预设亮度参数对应的理论亮度值。然而，对于位于所述第二位置的所述子像素而言，所述彩膜基板公共电极的电信号的电压值的变化会对位于所述第二位置的所述子像素的画面显示造成影响。其中，此处还是以所述显示面板中的所述彩膜基板公共电极整层设置为例进行说明，即所述第二公共电压等于所述第一公共电压Vcom，例如当所述第一目标公共电压和所述第二公共电压分别为(-2)V和0V时，所述第一差值为(-2)V。
S406，更新所述第二公共电压为所述第一目标公共电压。
其中，此处还是以所述显示面板中的所述彩膜基板公共电极整层设置为例进行说明，此时每一所述子像素对应的所述彩膜基板公共电极的电信号的电压值均等于所述第一目标公共电压Vcom'，即每一所述子像素的所述彩膜基板公共电极的电信号的电压值的变化值均等于所述第一差值，也即(Vcom'-Vcom)。
S407，获取所述显示面板中第二位置的第二像素电压和第二数据电压的差值作为第二差值。
其中，所述第二像素电压可以等于所述第二位置的所述子像素对应的所述电信号Vs稳定时的电压值，所述第二数据电压为此时连接于对应的所述数据线103的数据信号源输出的电信号的电压值。同理，位于所述第二位置的所述子像素还受到所述电信号Vd的衰减和所述耦合电容Cgs的影响，导致所述第二像素电压会小于所述第二数据电压，例如当所述第二像素电压和所述第二数据电压分别为3V和6V时，所述第二差值为(-3)V。
S408，根据所述第一差值、所述第二差值和所述显示面板中所述第二位置的第二预设数据电压，确定所述显示面板中所述第二位置的第二目标数据电压。
需要注意的是，与图5所示的实施例的不同点在于：图5所示的实施例中位于所述第一位置的所述子像素的画面显示情况仅受到由所述电信号Vd的衰减和所述耦合电容Cgs带来的影响，因此所述步骤S401至所述步骤S402仅根据所述第一补偿亮度参数和所述第一预设数据电压，即可确定所述显示面板中所述第一位置的第一目标数据电压；本实施例中位于所述第一位置的所述子像素的画面显示情况除了受到由所述电信号Vd的衰减和所述耦合电容Cgs带来的影响，还受到所述彩膜基板公共电极的电信号的电压值的变化带来的影响，因此所述步骤S408需要根据所述第一差值(Vcom'-Vcom)、所述第二差值和所述显示面板中所述第二位置的第二预设数据电压，才能确定所述显示面板中所述第二位置的第二目标数据电压。具体的，所述第二目标数据电压可以等于(第二预设数据电压+所述第一差值-所述第二差值)，例如当所述第二预设数据电压、所述第一差值和所述第二差值分别为10V、(-2)V和(-3)V时，所述第二目标数据电压为11V。
可以理解的，基于所述第二预设数据电压，结合所述第一差值、所述第二差值，可以计算出所述第二目标数据电压，即此时所述第二位置的所述子像素中与所述第二目标数据电压对应的所述薄膜晶体管T的漏极的实际电压值，可以等于所述第一位置的所述子像素中与所述第二预设数据电压对应的所述薄膜晶体管T的漏极的理论电压值，本实施例可以实现所述显示面板中所述第二位置处的所述子像素显示为与所述第二预设数据电压对应的理论亮度值，并且可以改善双极性显示中的画面闪烁现象。
可以理解的，本实施例和图5中的实施例相比较，增加了调整所述彩膜基板公共电极的电信号的电压值的步骤，可以选取位于所述显示面板中心区域的位置作为所述第一位置，这样，可以位于所述第一位置的所述子像素对应的所述第一目标公共电压为基准，调整其它位置的数据电压，相当于对所述彩膜基板公共电极的电信号的电压值进行了一次较为优质的校准，以减小所述彩膜基板公共电极的电信号的电压值的干扰，提高了调整其它位置的数据电压的可靠性。
在一实施例中，如图7所示，所述步骤S3之后可以包括但不限于如下步骤：
S302，获取所述显示面板中第三位置和所述第一位置的位置差异参数。
其中，所述位置差异参数可以为与所述第三位置和所述第一位置之间的相对位置相关的参数，例如所述位置差异参数的绝对值可以与所述第三位置和所述第一位置之间的距离呈正相关，又例如若所述第三位置相比较所述第一位置，更加靠近所述栅极线102或者所述数据线103的近端，则所述位置差异参数为负数，反之则为正数。
S303，根据所述位置差异参数和所述第一补偿亮度参数，确定所述显示面板中所述第三位置的第三补偿亮度参数。
可以理解的，此处可以所述第一补偿亮度参数为参考，结合所述位置差异参数，计算所述第三补偿亮度参数，所述第三补偿亮度参数可以所述第一补偿亮度参数和所述第一补偿亮度参数之和，例如当所述第一补偿亮度参数和所述位置差异参数分别为(-2)V和(-3)V时，所述第三补偿亮度参数为(-5)V。
在一实施例中，如图8所示，所述步骤S4还可以包括但不限于以下步骤。
S409，获取所述显示面板中所述第一位置的第一充电时长。
具体的，如图4(a)、图4(b)和图4(c)所示，所述电信号Vd在对应的高电平持续一段时间，导致对应的所述电信号Vs也在对应的稳定电压处持续一段时间，其中，每一所述子像素的实际亮度值和对应的所述电信号Vs的稳定电压值VS以及持续的时间均呈正相关。可以理解的，位于所述第一位置的所述子像素在所述第一充电时长中稳定时具有所述第一像素电压VS，所述第一充电时长可以等于所述周期T，当所述第一像素电压较小时，可以增加对应的所述第一充电时长来增加所述子像素的实际亮度值以至与所述第一数据电压对应的理论亮度值。
S4010，根据所述第一补偿亮度参数和所述第一充电时长，确定所述显示面板中所述第一位置的第一目标充电时长。
可以理解的，如图4(a)、图4(b)和图4(c)所示，可以认为所述电信号Vs在所述第一充电时长中的积分值为对应的所述子像素的实际亮度值，由于所述第一补偿亮度参数可以来自于所述第一参考亮度参数与所述第一实际亮度参数的差值，即在此之前已经获取了所述第一参考亮度参数与所述第一实际亮度参数，此处以所述第一实际亮度参数包括所述电信号Vd在对应的充电时长中的积分值，所述第一实际亮度参数包括所述电信号Vs在第三充电时长和所述第一充电时长中的积分值S1、所述电信号Vs平稳时的电压值，即所述第一像素电压VS，其中，所述第三充电时长为所述电信号Vs在由开始充电至达到所述平稳时的电压值经历的时长。具体的，可以根据所述第一实际亮度参数等于(S1+VS*t)，其中t等于所述第一目标充电时长减去所述第三充电时长和所述第一充电时长之和的值，从而得到所述第一目标充电时长。
在一实施例中，如图9所示，所述步骤S1还可以包括但不限于以下步骤。
S102，获取所述第一位置中的多个第一子位置的多个第一子实际亮度参数和多个第一子参考亮度参数。
其中，所述第一位置可以包括多个所述第一子位置，每一所述第一子位置设有对应的一个所述子像素，本实施例可以分别获取位于所述第一位置中的每一所述第一子位置处的所述子像素对应的所述第一子实际亮度参数和所述第一子参考亮度参数。

其中，所述第一实际亮度参数可以为多个所述第一子实际亮度参数的平均数，所述第一参考亮度参数可以为多个所述第一子参考亮度参数的平均数，即本实施例可以例如所述第一位置为单位确定对应的第一实际亮度参数和所述第一参考亮度参数，所述步骤S2至所述步骤S4可以所述第一位置为单位，对其中的多个所述第一子位置进行相同的处理，即所述第一预设亮度参数可以为多个所述子像素对应的多个第一子预设亮度参数的平均数，进一步的，所述第一位置中的每一所述第一子位置处的所述子像素具有相同的所述第一补偿亮度参数和相同的所述第一目标亮度参数。
