本申请实施例提供像素驱动方法，下面对本申请实施例的像素驱动方法的各个步骤进行详细说明。
在一实施例中，如图1所示，所述像素驱动方法包括但不限于如下步骤。
S1，配置过驱动电压值表，所述过驱动电压值表包括一一对应的多个初始灰阶值和多个目标灰阶值，每一所述初始灰阶值和每一所述目标灰阶值具有对应的过驱动电压值，多个所述目标灰阶值包括第一目标灰阶值、多个第二目标灰阶值和第三目标灰阶值，每一所述第二目标灰阶值大于所述第一目标灰阶值且小于所述第三目标灰阶值，所述第一目标灰阶值与不等于所述第一目标灰阶值的每一所述初始灰阶值对应的所述过驱动电压值相同，所述第三目标灰阶值与不等于所述第三目标灰阶值的每一所述初始灰阶值对应的所述过驱动电压值相同。
其中，本申请中的像素驱动方法可以应用于显示面板，如图2所示，所述显示面板可以液晶显示面板，液晶显示面板可以包括相对设置的阵列基板层10和彩膜基板层20、设于阵列基板层10和彩膜基板层20之间的液晶层30以及位于阵列基板层10远离彩膜基板层20一侧的背光层40。具体的，阵列基板层10包括阵列排布且一一对应的多个像素驱动单元101和多个子像素电极102，每一子像素电极102电性连接至对应的像素驱动单元101以被加载对应的像素电压，彩膜基板层20包括彩膜层201以及位于彩膜层201靠近阵列基板层10的一侧且整层设置的公共电极层202，公共电极层202加载有公共电压，液晶层30包括与多个子像素电极102一一对应的多个液晶单元301，每一液晶单元301中的多个液晶分子在对应的子像素电极102所具有的像素电压以及公共电极层202所具有的公共电压的作用下偏转相应的角度，使得背光层40发出的光线可以以相应的光量穿过液晶层30，并且结合彩膜层201的作用以实现画面显示。
具体的，每一像素驱动单元101、对应的子像素电极102和对应的液晶单 元301可以组成为一子像素，其中，由于多个子像素具有相同的公共电压，每一子像素可以在对应的像素电压的控制下以实现不同的透光率从而呈现为不同的灰阶值，即每一子像素的每一灰阶值具有对应的像素电压值。具体的，每一像素电压值可以具有对应的数据电压值，在进行画面显示时，可以根据每一子像素所需呈现的灰阶值确定对应的数据电压值，如图2所示，可以向对应的像素驱动单元101传输值为对应的数据电压值的数据电压，以使像素驱动单元101向对应的子像素电极102加载为值为对应的像素电压值的像素电压，从而驱动对应的液晶单元301中的多个液晶分子偏转。其中，子像素的灰阶值所对应的像素电压值和数据电压值可以相等。需要注意的是，受限于液晶分子的偏转速度，导致液晶分子由当前帧的位置偏转至待显示帧的位置所需时间较长，即在一帧内液晶分子无法偏转足够的角度造成对应的子像素无法达到预期的显示亮度，呈现为画面拖尾的现象，降低了显示面板的画面显示质量。
具体的，本实施例中的过驱动电压值表中的每一初始灰阶值可以理解为子像素在当前帧所需呈现的灰阶值，每一目标灰阶值可以理解为子像素在待显示帧所需呈现的灰阶值，本实施例中每一初始灰阶值和每一目标灰阶值具有对应的过驱动电压值，此处的过驱动电压值可以理解为直接或者间接作用于子像素对应的子像素电极102上，使得对应的液晶单元301中的多个液晶分子偏转，以实现对应的子像素由“当前帧所需呈现的灰阶值切换至待显示帧所需呈现的灰阶值”的电压的值。
可以理解的，此处以驱动电压为上文提及的“数据电压”为例进行说明，本实施例中的过驱动电压值表中的多个过驱动电压值可以结合OD(Over Driver,过驱动)技术的原理进行设置，即本实施例中的子像素在其中一目标灰阶值对应的过驱动电压值，可以不同于子像素在待显示帧所需呈现的灰阶值等于目标灰阶值时对应的数据电压值，而是需要结合初始灰阶值设置对应的过驱动电压值，以改善液晶分子偏转较慢的问题。基于此，本实施例中对第一目标灰阶值和第三目标灰阶值的具体数值不做限定，只需满足第一目标灰阶值和第 三目标灰阶值之间存在多个第二目标灰阶值，且基于数值较小的第一目标灰阶值，与多个初始灰阶值(除去不等于所述第一目标灰阶值的)一一对应的多个过驱动电压值为一相同的值，且基于数值较大的第三目标灰阶值，与多个初始灰阶值(除去不等于所述第三目标灰阶值的)一一对应的多个过驱动电压值设置为另一相同的值。
S2，获取子像素的待显示帧的灰阶值，并将所述过驱动电压值表中相同于所述待显示帧的灰阶值的所述目标灰阶值所对应的所述过驱动电压值设置为驱动电压的值。
其中，本步骤中的“待显示帧的灰阶值”即上文提及的“显示帧所需呈现的灰阶值”。具体的，结合上文论述，如图2所示，在本实施例中，无论子像素的当前帧所需呈现的灰阶值为任一初始灰阶值，若子像素的待显示帧的灰阶值为第一目标灰阶值，则对应一相等的过驱动电压值，若子像素的待显示帧的灰阶值为第三目标灰阶值，则对应另一相等的过驱动电压值。其中，驱动电压可以理解为上文提及的“像素电压”或者“数据电压”。
S3，根据所述驱动电压，驱动所述子像素发光以显示待显示帧的画面。
具体的，本实施例中可以先设置过驱动电压值表，再至少根据子像素的待显示帧的灰阶值和过驱动电压值表中的多个目标灰阶值之间的关系，确定并将对应的过驱动电压值设置为驱动电压，以使得对应的子像素电极102加载为对应的像素电压，结合上文论述，驱动对应的液晶单元301中的多个液晶分子偏转相应的角度实现对应量的透光。
可以理解的，至少基于第一目标灰阶值、多个第二目标灰阶值和第三目标灰阶值而言，第一目标灰阶值为最小值，对于子像素由当前帧所需呈现的灰阶值为任一初始灰阶值(除去不等于所述第一目标灰阶值的)切换至第一目标灰阶值而言，即可以理解为子像素的灰阶值朝着减小的方向移动，而本实施例均将相等的一过驱动电压值设置为驱动电压的值，此处对应于第一目标灰阶值的过驱动电压值可以理解为最有助于子像素的灰阶值朝着减小的方向移动的驱 动电压的值；同理，第三目标灰阶值为最大值，对于子像素由当前帧所需呈现的灰阶值为任一初始灰阶值(除去不等于所述第三目标灰阶值的)切换至第三目标灰阶值而言，即可以理解为子像素的灰阶值朝着增加的方向移动，而本实施例均将相等的另一过驱动电压值设置为驱动电压的值，此处对应于第三目标灰阶值的过驱动电压值可以理解为最有助于子像素的灰阶值朝着增加的方向移动的驱动电压的值。因此，本实施例中通过统一化较小的第一目标灰阶值对应的多个过驱动电压值，以及统一化较大的第三目标灰阶值对应的多个过驱动电压值，可以最快地分别驱动液晶分子偏转至两者相应的角度，进一步改善了画面拖尾的现象，提高了显示面板的画面显示质量。
在一实施例中，所述第一目标灰阶值为所述子像素的灰阶值的最小值，所述第一目标灰阶值对应的所述过驱动电压值与所述子像素的灰阶值相同于所述第一目标灰阶值时对应的所述数据电压值相同；所述第三目标灰阶值为所述子像素的灰阶值的最大值，所述第三目标灰阶值对应的所述过驱动电压值与所述子像素的灰阶值相同于所述第三目标灰阶值时对应的所述数据电压值相同。
可以理解的，基于“所述第一目标灰阶值为所述子像素的灰阶值的最小值”以及“所述第三目标灰阶值为所述子像素的灰阶值的最大值”可知，子像素的灰阶值为第一目标灰阶值时对应的数据电压值可以理解为数据电压值的最小值，即可以对应液晶分子偏转的最小角度，同理，子像素的灰阶值为第三目标灰阶值时对应的数据电压值可以理解为数据电压值的最大值，即可以对应液晶分子偏转的最大角度。具体的，此处以第一目标灰阶值为0、第三目标灰阶值为255为例进行说明，如表1所示，其中“X”表示初始灰阶值，“Y”表示目标灰阶值，观察可知，Y等于0时，X等于51、204或者255所对应的多个过驱动电压值V (51,0)、V (204,0)、V (255,0)均相等，可以等于灰阶值为0时对应的数据电压值V’ 0，同样地，Y等于255时，X等于0、51或者204所对应的多个过驱动电压值V (0,255)、V (51,255)、V (204,255)均相等，可以等于灰阶值为255时对应的数据电压值V’ 255。需要注意的是，当初始灰阶值“X”相同于目标灰阶值“Y” 时，表示液晶分子的偏转角度无需变化，此时维持数据电压值为灰阶值等于初始灰阶值或者目标灰阶值所对应的数据电压值即可。

因此，本实施例中的通过统一化相等于灰阶值的最小值的第一目标灰阶值对应的多个过驱动电压值为数据电压值的最小值，即采用数据电压值的最小值直接或者间接驱动液晶分子偏转，可以最快地驱动液晶分子偏转至最小角度，同理，本实施例中的通过统一化相等于灰阶值的最大值的第三目标灰阶值对应的多个过驱动电压值为数据电压值的最大值，即采用数据电压值的最大值直接或者间接驱动液晶分子偏转，可以最快地驱动液晶分子偏转至最大角度，均可以进一步改善画面拖尾的现象，以提高显示面板的画面显示质量。
在一实施例中，如图3所示，步骤S2可以包括但不限于如下步骤。
S201，获取所述待显示帧的灰阶值与多个所述目标灰阶值之间的关系。
具体的，结合上文论述，由于第一目标灰阶值与每一初始灰阶值对应的过驱动电压值相同，第三目标灰阶值与每一初始灰阶值对应的过驱动电压值相同，即步骤S2中驱动电压的值和确定方式首先应该考虑待显示帧的灰阶值与多个目标灰阶值之间的关系，具体为可以判断待显示帧的灰阶值是否相等于任一第二目标灰阶值。
当所述待显示帧的灰阶值相同于所述第一目标灰阶值时，执行S202，将 所述第一目标灰阶值对应的所述过驱动电压值设置为所述驱动电压的值。具体的，结合上文论述，由于第一目标灰阶值与每一初始灰阶值对应的过驱动电压值相同，则在判断为待显示帧的灰阶值相同于第一目标灰阶值时，无论初始灰阶值的大小，对应的驱动电压的值均为第一目标灰阶值对应的过驱动电压值，进一步的，可以为数据电压值的最小值。
当所述待显示帧的灰阶值相同于所述第三目标灰阶值时，执行S203，将所述第三目标灰阶值对应的所述过驱动电压值设置为所述驱动电压的值。同理，由于第三目标灰阶值与每一初始灰阶值对应的过驱动电压值相同，则在判断为待显示帧的灰阶值相同于第三目标灰阶值时，无论初始灰阶值的大小，对应的驱动电压的值均为第三目标灰阶值对应的过驱动电压值，进一步的，可以为数据电压值的最大值。
当所述待显示帧的灰阶值相同于所述第二目标灰阶值时，执行S204，获取所述子像素的当前显示帧的灰阶值，并将所述过驱动电压值表中相同于所述当前显示帧的灰阶值的所述初始灰阶值、且相同于所述待显示帧的灰阶值的所述第二目标灰阶值两者所对应的所述过驱动电压值设置为所述驱动电压的值。具体的，结合上文论述，每一初始灰阶值和每一目标灰阶值具有对应的过驱动电压值，本实施例中进一步限定相同于第二目标灰阶值的待显示帧的灰阶值对应的驱动电压的值，不仅和待显示帧的灰阶值与多个目标灰阶值的关系，还和当前显示帧的灰阶值与多个初始灰阶值的关系两者均相关。
可以理解的，由于任一第二目标灰阶值不等于多个目标灰阶值的最小值或者最大值，即还存在大于或者小于第二目标灰阶值的目标灰阶值，导致当前显示帧的灰阶值向待显示帧的灰阶值切换时存在两种方向；因此，本实施例中基于待显示帧的灰阶值相同于第二目标灰阶值，考虑到当前显示帧的灰阶值与多个初始灰阶值的关系，从而确定当前显示帧的灰阶值向待显示帧的灰阶值切换的方向，可以提高改善画面拖尾的现象的精确性，进一步提高显示面板的画面显示质量。
在一实施例中，多个所述初始灰阶值包括小于所述第二目标灰阶值的第一初始灰阶值，所述第一初始灰阶值和所述第二目标灰阶值对应的所述过驱动电压值，大于所述子像素的灰阶值相同于所述第二目标灰阶值时对应的所述数据电压值。其中，在多个初始灰阶值中，第一初始灰阶值小于第二目标灰阶值，结合上文论述，第一初始灰阶值和第二目标灰阶值对应的过驱动电压值可以理解为：子像素在当前帧所需呈现的灰阶值等于第一初始灰阶值切换至待显示帧所需呈现的灰阶值等于第二目标灰阶值，所需的作用于子像素对应的子像素电极102的数据电压的值。
可以理解的，本实施例中考虑到第一初始灰阶值小于第二目标灰阶值，即子像素的当前帧所需呈现的灰阶值小于待显示帧所需呈现的灰阶值，即子像素的灰阶值向增加的方向变化，而本实施例中将第一初始灰阶值和第二目标灰阶值对应的过驱动电压值，设置为大于子像素的灰阶值相同于第二目标灰阶值时对应的数据电压值，可以使得数据电压的值有所增大，以使得作用于液晶分子的作用力进一步增加，更有助于液晶分子由较小的偏转角度向较大的偏转角度变化，以更快地驱动液晶分子偏转至相应的角度，进一步改善了画面拖尾的现象，提高了显示面板的画面显示质量。
具体的，如表1所示，例如在目标灰阶值“Y”等于第二目标灰阶值51时，初始灰阶值“X”等于第一初始灰阶值0所对应的过驱动电压值V (0,51)可以大于灰阶值等于51时对应的数据电压值V’ 51，即可以提高液晶分子偏转至与灰阶值等于51所对应的角度的速度；又例如在目标灰阶值“Y”等于第二目标灰阶值204时，初始灰阶值“X”等于第一初始灰阶值0所对应的过驱动电压值V (0,204)可以大于灰阶值等于204时对应的数据电压值V’ 204，同理，过驱动电压值V (51,204)可以大于数据电压值V’ 204，过驱动电压值V (51,204)可以大于数据电压值V’ 204，即可以提高液晶分子偏转至与灰阶值等于204所对应的角度的速度。
在一实施例中，多个所述初始灰阶值包括均小于所述第二目标灰阶值的第 三初始灰阶值和第四初始灰阶值，所述第三初始灰阶值小于所述第四初始灰阶值；其中，所述第三初始灰阶值和所述第二目标灰阶值对应的所述过驱动电压值，大于所述第四初始灰阶值和所述第二目标灰阶值对应的所述过驱动电压值。其中，在多个初始灰阶值中，第三初始灰阶值和第四初始灰阶值均小于第二目标灰阶值，结合上文论述，基于待显示帧所需呈现的灰阶值对应同一第二目标灰阶值，由于第三初始灰阶值小于第四初始灰阶值，子像素在当前帧所需呈现的灰阶值等于第三初始灰阶值对应的液晶分子的偏转难度，大于子像素在当前帧所需呈现的灰阶值等于第四初始灰阶值对应的液晶分子的偏转难度。
可以理解的，本实施例中考虑到基于同一第二目标灰阶值，第三初始灰阶值对应的液晶分子的偏转难度，大于第四初始灰阶值对应的液晶分子的偏转难度，将第三初始灰阶值和第二目标灰阶值对应的过驱动电压值，设置为大于第四初始灰阶值和第二目标灰阶值对应的所述过驱动电压值，以使得第三初始灰阶值所对应的作用于液晶分子的数据电压的值进一步增大，以使得作用于液晶分子的作用力进一步增加，更有助于液晶分子由更小的偏转角度向较大的偏转角度变化，以更快地驱动液晶分子偏转至相应的角度，进一步改善了画面拖尾的现象，提高了显示面板的画面显示质量。进一步的，对于任一相同的第二目标灰阶值而言，通过合理地设置第三初始灰阶值和第二目标灰阶值对应的过驱动电压值、第四初始灰阶值和第二目标灰阶值对应的过驱动电压值，在基于液晶分子的偏转速度提高的前提下，可以实现液晶分子偏转至对应于第二目标灰阶值的偏转角度的时间相同，甚至可以实现液晶分子由任一初始灰阶值偏转至任一目标灰阶值的时间相同。
具体的，如表1所示，例如在目标灰阶值“Y”等于第二目标灰阶值204时，初始灰阶值“X”等于第一初始灰阶值0所对应的过驱动电压值V (0,204)可以大于初始灰阶值“X”等于第一初始灰阶值51所对应的过驱动电压值V (51,204)，即可以提高液晶分子由灰阶值等于0偏转至与灰阶值等于204所对应的角度的速度，进一步的，可以使得液晶分子由灰阶值等于0偏转至与灰阶值等于204 所对应的角度的速度，等于液晶分子由灰阶值等于51偏转至与灰阶值等于204所对应的角度的速。
在一实施例中，多个所述初始灰阶值包括大于所述第二目标灰阶值的第二初始灰阶值，所述第二初始灰阶值和所述第二目标灰阶值对应的所述过驱动电压值，小于所述子像素的灰阶值相同于所述第二目标灰阶值时对应的所述数据电压值。其中，在多个初始灰阶值中，第二初始灰阶值大于第二目标灰阶值，结合上文论述，第二初始灰阶值和第二目标灰阶值对应的过驱动电压值可以理解为：子像素在当前帧所需呈现的灰阶值等于第二初始灰阶值切换至待显示帧所需呈现的灰阶值等于第二目标灰阶值，所需的作用于子像素对应的子像素电极102的数据电压的值。
可以理解的，本实施例中考虑到第二初始灰阶值大于第二目标灰阶值，即子像素的当前帧所需呈现的灰阶值大于待显示帧所需呈现的灰阶值，即子像素的灰阶值向减小的方向变化，而本实施例中将第二初始灰阶值和第二目标灰阶值对应的过驱动电压值，设置为小于子像素的灰阶值相同于第二目标灰阶值时对应的数据电压值，可以使得数据电压的值有所减小，以使得作用于液晶分子的作用力进一步减小，更有助于液晶分子由较大的偏转角度向较小的偏转角度变化，以更快地驱动液晶分子偏转至相应的角度，进一步改善了画面拖尾的现象，提高了显示面板的画面显示质量。
具体的，如表1所示，例如在目标灰阶值“Y”等于第二目标灰阶值51时，初始灰阶值“X”等于第一初始灰阶值204所对应的过驱动电压值V (204,51)可以小于灰阶值等于51时对应的数据电压值V’ 51，同理，过驱动电压值V (255,51)可以小于数据电压值V’ 51，即可以提高液晶分子偏转至与灰阶值等于51所对应的角度的速度；又例如在目标灰阶值“Y”等于第二目标灰阶值204时，初始灰阶值“X”等于第一初始灰阶值255所对应的过驱动电压值V (255,204)可以小于灰阶值等于204时对应的数据电压值V’ 204，即可以提高液晶分子偏转至与灰阶值等于204所对应的角度的速度。
在一实施例中，多个所述初始灰阶值包括均大于所述第二目标灰阶值的第五初始灰阶值和第六初始灰阶值，所述第五初始灰阶值大于所述第六初始灰阶值；其中，所述第五初始灰阶值和所述第二目标灰阶值对应的所述过驱动电压值，大于所述第六初始灰阶值和所述第二目标灰阶值对应的所述过驱动电压值。其中，在多个初始灰阶值中，第五初始灰阶值和第六初始灰阶值均大于第二目标灰阶值，结合上文论述，基于待显示帧所需呈现的灰阶值对应同一第二目标灰阶值，由于第五初始灰阶值大于第六初始灰阶值，子像素在当前帧所需呈现的灰阶值等于第五初始灰阶值对应的液晶分子的偏转难度，大于子像素在当前帧所需呈现的灰阶值等于第六初始灰阶值对应的液晶分子的偏转难度。
可以理解的，本实施例中考虑到基于同一第二目标灰阶值，第五初始灰阶值对应的液晶分子的偏转难度，大于第六初始灰阶值对应的液晶分子的偏转难度，将第五初始灰阶值和第二目标灰阶值对应的过驱动电压值，设置为大于第六初始灰阶值和第二目标灰阶值对应的所述过驱动电压值，以使得第五初始灰阶值所对应的作用于液晶分子的数据电压的值进一步减小，以使得作用于液晶分子的作用力进一步减小，更有助于液晶分子由更大的偏转角度向较小的偏转角度变化，以更快地驱动液晶分子偏转至相应的角度，进一步改善了画面拖尾的现象，提高了显示面板的画面显示质量。进一步的，对于任一相同的第二目标灰阶值而言，通过合理地设置第五初始灰阶值和第二目标灰阶值对应的过驱动电压值、第六初始灰阶值和第二目标灰阶值对应的过驱动电压值，在基于液晶分子的偏转速度提高的前提下，可以实现液晶分子偏转至对应于第二目标灰阶值的偏转角度的时间相同，甚至可以实现液晶分子由任一初始灰阶值偏转至任一目标灰阶值的时间相同。
具体的，如表1所示，例如在目标灰阶值“Y”等于第二目标灰阶值51时，初始灰阶值“X”等于第一初始灰阶值255所对应的过驱动电压值V (255,51)可以大于初始灰阶值“X”等于第一初始灰阶值204所对应的过驱动电压值V (204,51)，即可以提高液晶分子由灰阶值等于255偏转至与灰阶值等于51所对 应的角度的速度，进一步的，可以使得液晶分子由灰阶值等于255偏转至与灰阶值等于51所对应的角度的速度，等于液晶分子由灰阶值等于204偏转至与灰阶值等于51所对应的角度的速度。
为了更好地实施以上方法，在一实施例中提供了像素驱动装置。
请参考图4，图4为本申请实施例提供的像素驱动装置的结构示意图，本实施例的像素驱动装置的具体描述如下。
在一实施例中，所述像素驱动装置50可以包括但不限于以下模块。
配置模块501，用于配置过驱动电压值表，所述过驱动电压值表包括一一对应的多个初始灰阶值和多个目标灰阶值，每一所述初始灰阶值和每一所述目标灰阶值具有对应的过驱动电压值，多个所述目标灰阶值包括第一目标灰阶值、多个第二目标灰阶值和第三目标灰阶值，每一所述第二目标灰阶值大于所述第一目标灰阶值且小于所述第三目标灰阶值，所述第一目标灰阶值与不等于所述第一目标灰阶值的每一所述初始灰阶值对应的所述过驱动电压值相同，所述第三目标灰阶值与不等于所述第三目标灰阶值的每一所述初始灰阶值对应的所述过驱动电压值相同。
其中，本申请中的像素驱动装置50可以应用于显示面板，如图2所示，所述显示面板可以液晶显示面板，显示面板的具体结构可以参考上文的相关描述。
具体的，本实施例中的过驱动电压值表中的每一初始灰阶值、每一目标灰阶值、每一初始灰阶值和每一目标灰阶值具有对应的过驱动电压值可以参考上文的相关描述。其中，配置模块501可以电性连接至显示面板，过驱动电压值表可以但不限于存储于配置模块501或者显示面板内。
可以理解的，此处以驱动电压为上文提及的“数据电压”为例进行说明，本实施例中的过驱动电压值表中的多个过驱动电压值可以结合OD(Over Driver,过驱动)技术的原理进行设置，即本实施例中的子像素在其中一目标灰阶值对应的过驱动电压值，可以不同于子像素在待显示帧所需呈现的灰阶值等 于目标灰阶值时对应的数据电压值，而是需要结合初始灰阶值设置对应的过驱动电压值，以改善液晶分子偏转较慢的问题。基于此，本实施例中对第一目标灰阶值和第三目标灰阶值的具体数值不做限定，只需满足第一目标灰阶值和第三目标灰阶值之间存在多个第二目标灰阶值，且基于数值较小的第一目标灰阶值，与多个初始灰阶值(除去不等于所述第一目标灰阶值的)一一对应的多个过驱动电压值为一相同的值，且基于数值较大的第三目标灰阶值，与多个初始灰阶值(除去不等于所述第三目标灰阶值的)一一对应的多个过驱动电压值设置为另一相同的值。
处理模块502，用于获取子像素的待显示帧的灰阶值，并将所述过驱动电压值表中相同于所述待显示帧的灰阶值的所述目标灰阶值所对应的所述过驱动电压值设置为驱动电压的值。
其中，处理模块502可以电性连接至显示面板，子像素的待显示帧的灰阶值可以但不限于存储于处理模块502或者显示面板内。其中，处理模块502获取的“待显示帧的灰阶值”即上文提及的“显示帧所需呈现的灰阶值”。具体的，结合上文论述，如图2所示，在本实施例中，无论子像素的当前帧所需呈现的灰阶值为任一初始灰阶值，若子像素的待显示帧的灰阶值为第一目标灰阶值，则对应一相等的过驱动电压值，若子像素的待显示帧的灰阶值为第三目标灰阶值，则对应另一相等的过驱动电压值。其中，驱动电压可以理解为上文提及的“像素电压”或者“数据电压”。
驱动模块503，用于根据所述驱动电压，驱动所述子像素发光以显示待显示帧的画面。
具体的，本实施例中可以先设置过驱动电压值表，处理模块502再至少根据子像素的待显示帧的灰阶值和过驱动电压值表中的多个目标灰阶值之间的关系，确定并将对应的过驱动电压值设置为驱动电压，驱动模块503再控制对应的子像素电极102加载为对应的像素电压，结合上文论述，驱动对应的液晶单元301中的多个液晶分子偏转相应的角度实现对应量的透光。
可以理解的，至少基于第一目标灰阶值、多个第二目标灰阶值和第三目标灰阶值而言，第一目标灰阶值为最小值，对于子像素由当前帧所需呈现的灰阶值为任一初始灰阶值(除去不等于所述第一目标灰阶值的)切换至第一目标灰阶值而言，即可以理解为子像素的灰阶值朝着减小的方向移动，而本实施例均将相等的一过驱动电压值设置为驱动电压的值，此处对应于第一目标灰阶值的过驱动电压值可以理解为最有助于子像素的灰阶值朝着减小的方向移动的驱动电压的值；同理，第三目标灰阶值为最大值，对于子像素由当前帧所需呈现的灰阶值为任一初始灰阶值(除去不等于所述第三目标灰阶值的)切换至第三目标灰阶值而言，即可以理解为子像素的灰阶值朝着增加的方向移动，而本实施例均将相等的另一过驱动电压值设置为驱动电压的值，此处对应于第三目标灰阶值的过驱动电压值可以理解为最有助于子像素的灰阶值朝着增加的方向移动的驱动电压的值。因此，本实施例中通过统一化较小的第一目标灰阶值对应的多个过驱动电压值，以及统一化较大的第三目标灰阶值对应的多个过驱动电压值，可以最快地驱动液晶分子偏转至相应的角度，进一步改善了画面拖尾的现象，提高了显示面板的画面显示质量。
