需要注意的是，附图中各图形的尺寸和形状不反映真实比例，目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。
参见图1，显示装置可以包括显示面板100、电平转换(Level Shift)电路200以及时序控制器300。其中，显示面板100可以包括多个阵列排布的像素单元，多条栅线(例如，GA1、GA2、GA3、GA4)、多条数据线(例如，DA1、DA2、DA3)、栅极驱动电路110以及源极驱动电路120。栅极驱动电路110分别与栅线GA1、GA2、GA3、GA4耦接，源极驱动电路120分别与数据线DA1、DA2、DA3耦接。其中，时序控制器300向电平转换(Level Shift)电路200输入控制信号，以使电平转换(Level Shift)电路200向栅极驱动电路110输入控制信号，从而驱动栅线GA1、GA2、GA3、GA4。时序控制器300向源极驱动电路120输入信号，以使源极驱动电路120向数据线输入灰阶电压，从而对子像素充电，实现显示功能。
示例性地，每个像素单元包括多个子像素SPX。例如，像素单元可以包括红色子像素，绿色子像素以及蓝色子像素，这样可以通过红绿蓝进行混色，以实现彩色显示。或者，像素单元也可以包括红色子像素，绿色子像素、蓝色子像素以及白色子像素，这样可以通过红绿蓝白进行混色，以实现彩色显示。当然，在实际应用中，像素单元中的子像素的发光颜色可以根据实际应用环境来设计确定，在此不作限定。
参见图1所示，每个子像素中包括晶体管01和像素电极02。其中，一行子像素对应一条栅线，一列子像素对应一条数据线。晶体管01的栅极与对应的栅线电连接，晶体管01的源极与对应的数据线电连接，晶体管01的漏极与像素电极02电连接，需要说明的是，本公开像素阵列结构还可以是双栅结构，即相邻两行像素之间设置两条栅极线，此排布方式可以减少一半的数据线，即包含相邻两列像素之间有的数据线，有的相邻两列像素之间不包括数据线，具体像素排布结构和数据线，扫描线的排布方式不限定。
灰阶，一般是将最暗与最亮之间的亮度变化区分为若干份，以便于进行 屏幕亮度管控。例如，以显示的图像由红、绿、蓝三种颜色组成，其中每一个颜色都可以显现出不同的亮度级别，并且不同亮度层次的红、绿、蓝组合起来，可以形成不同的色彩。例如，液晶显示面板的灰阶位数为6bit，则红、绿、蓝这三种颜色分别具有64(即2 6)个灰阶，这64个灰阶值分别为0～63。液晶显示面板的灰阶位数为8bit，则红、绿、蓝这三种颜色分别具有256(即2 8)个灰阶，这256个灰阶值分别为0～255。液晶显示面板的灰阶位数为10bit，则红、绿、蓝这三种颜色分别具有1024(即2 10)个灰阶，这1024个灰阶值分别为0～1023。液晶显示面板的灰阶位数为12bit，则红、绿、蓝这三种颜色分别具有4096(即2 12)个灰阶，这4096个灰阶值分别为0～4093。
需要说明的是，本公开实施例中的显示面板可以为液晶显示面板。示例性地，液晶显示面板一般包括对盒的上基板和下基板，以及填充在上基板和下基板之间的液晶分子。在显示画面时，由于加载在各子像素的像素电极上的灰阶电压和公共电极上的电压之间具有电压差，该电压差可以形成电场，从而使液晶分子在该电场的作用下进行偏转。由于不同强度的电场使液晶分子的偏转程度不同，从而导致子像素的透过率不同，以使子像素实现不同灰阶的亮度，进而实现画面显示。
下面均以本公开实施例中的显示面板为液晶显示面板，且像素单元包括红色子像素、绿色子像素、蓝色子像素为例进行说明，但是读者应知，液晶显示面板中包括的子像素的颜色并不局限于此。
由于液晶分子具有粘滞效应，因此液晶分子偏转至预期状态会有一个时间过程，即响应时间。其中，液晶分子偏转的越快，其响应时间越短。液晶分子偏转的越慢，其响应时间越长。随着显示面板的分辨率越来越高，导致子像素的充电时间越来越短，造成子像素的充电率不足的情况，从而使得液晶分子偏转的相对较慢，导致液晶分子的响应时间相对较长，从而在显示图像时会出现残留图像的问题。
出现残留图像的问题，尤其是在输入子像素的电压，由低灰阶转换为高灰阶时较为明显。结合图2所示，以灰阶位数为6bit的显示面板为例，在显 示面板显示以255灰阶作为背景且0灰阶作为数字8的测试画面时，W1对应的数字8为第一帧的测试画面中数字8所在的位置，W2对应的数字8为第二帧的测试画面中数字8所在的位置，W3对应的数字8为第三帧的测试画面中数字8所在的位置。通过图2可知，在第二帧时，W1对应的数字8并不会立刻变成白色，出现了残留图像。在第三帧时，W2对应的数字8也不会立刻变成白色，也出现了残留图像。
为了提高液晶分子的响应速度，降低响应时间，本公开实施例提供了显示面板的驱动方法，如图3所示，可以包括如下步骤：
S10、获取当前帧的显示数据和上一帧的显示数据。
示例性地，结合图4a所示，在一个视频中，可以通过连续的帧显示画面。其中，以在该视频的第n-1帧至第n+2帧F(n-1)～F(n+2)为例，在将要显示第n帧F(n)的画面时，可以将第n帧F(n)作为当前帧，将第n-1帧F(n-1)作为上一帧，这样可以获取第n帧F(n)的显示数据和第n-1帧F(n-1)的显示数据。在将要显示第n+1帧F(n+1)的画面时，可以将第n+1帧F(n+1)作为当前帧，将第n帧F(n)作为上一帧，这样可以获取第n帧F(n)的显示数据和第n+1帧F(n+1)的显示数据。其余依次类推，在此不作赘述。
需要说明的是，获取到的当前帧的显示数据和上一帧的显示数据，是携带有的默认灰阶位数的初始显示数据，并未将携带的默认灰阶位数转换为目标灰阶位数。
S20、判断当前帧的显示数据和上一帧的显示数据是否相同。
示例性地，在将要显示第n帧F(n)的画面时，可以将第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据中，对应同一子像素的显示数据进行比较，以将每一个子像素对应的显示数据均比较完。
若每一个子像素中，同一子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是相同的，则说明第n帧F(n)将要显示的画面和第n-1帧F(n-1)已经显示的画面是相同的。也就是说，第n帧F(n)和第n-1帧F(n-1)显示的画面未进行切换，即显示的是静态画面。此时，子像素对应灰阶不跳 变，从而不用进行灰阶位数对应的灰阶电压的转换。则可以执行步骤S40、直接根据当前帧的显示数据的默认灰阶电压，以驱动显示面板显示。
若每一个子像素中，有部分子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是相同的，其余部分子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是不相同的。或者，全部子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是不相同的。则说明第n帧F(n)将要显示的画面和第n-1帧F(n-1)已经显示的画面是不相同的。也就是说，第n帧F(n)和第n-1帧F(n-1)显示的画面进行了切换，即显示的是动态画面。此时，其余部分子像素对应灰阶进行了跳变，这样可以进行灰阶位数对应的灰阶电压的转换。则可以执行步骤S30。
在将要显示第n+1帧F(n+1)的画面时，可以将第n+1帧F(n+1)的显示数据与第n帧F(n)的显示数据中，对应同一子像素的显示数据进行比较，以将每一个子像素对应的显示数据均比较完。若每一个子像素中，同一子像素对应的第n帧F(n)的显示数据与第n+1帧F(n+1)的显示数据是相同的，则说明第n帧F(n)将要显示的画面和第n+1帧F(n+1)已经显示的画面是相同的。也就是说，第n帧F(n)和第n+1帧F(n+1)显示的画面未进行切换，即显示的是静态画面。此时，子像素对应灰阶不跳变，从而不用进行灰阶位数对应的灰阶电压的转换。则可以执行步骤S40、直接根据当前帧的显示数据的默认灰阶电压，以驱动显示面板显示。
若每一个子像素中，有部分子像素对应的第n帧F(n)的显示数据与第n+1帧F(n+1)的显示数据是相同的，其余部分子像素对应的第n帧F(n)的显示数据与第n+1帧F(n+1)的显示数据是不相同的。或者，全部子像素对应的第n帧F(n)的显示数据与第n+1帧F(n+1)的显示数据是不相同的。则说明第n帧F(n)将要显示的画面和第n+1帧F(n+1)已经显示的画面是不相同的。也就是说，第n帧F(n)和第n+1帧F(n+1)显示的画面进行了切换，即显示的是动态画面。此时，其余部分子像素对应灰阶进行了跳变，这样可以进行灰阶位数对应的灰阶电压的转换。则可以执行步骤S30。
在将要显示第n+2帧F(n+2)的画面时，可以将第n+1帧F(n+1)的显示数据与第n+2帧F(n+2)的显示数据中，对应同一子像素的显示数据进行比较，以将每一个子像素对应的显示数据均比较完。若每一个子像素中，同一子像素对应的第n+2帧F(n+2)的显示数据与第n+1帧F(n+1)的显示数据是相同的，则说明第n+2帧F(n+2)将要显示的画面和第n+1帧F(n+1)已经显示的画面是相同的。也就是说，第n+2帧F(n+2)和第n+1帧F(n+1)显示的画面未进行切换，即显示的是静态画面。此时，子像素对应灰阶不跳变，从而不用进行灰阶位数对应的灰阶电压的转换。则可以执行步骤S40、直接根据当前帧的显示数据的默认灰阶电压，以驱动显示面板显示。
若每一个子像素中，有部分子像素对应的第n+2帧F(n+2)的显示数据与第n+1帧F(n+1)的显示数据是相同的，其余部分子像素对应的第n+2帧F(n+2)的显示数据与第n+1帧F(n+1)的显示数据是不相同的。或者，全部子像素对应的第n+2帧F(n+2)的显示数据与第n+1帧F(n+1)的显示数据是不相同的。则说明第n+2帧F(n+2)将要显示的画面和第n+1帧F(n+1)已经显示的画面是不相同的。也就是说，第n+2帧F(n+2)和第n+1帧F(n+1)显示的画面进行了切换，即显示的是动态画面。此时，其余部分子像素对应灰阶进行了跳变，这样可以进行灰阶位数对应的灰阶电压的转换。则可以执行步骤S30。
其余帧，可以根据上述方式进行判断，以确定需要根据步骤S30还是步骤S40驱动显示面板进行显示。
S30、将当前帧的显示数据携带的默认灰阶位数的默认灰阶电压中，对应至少一个子像素的默认灰阶电压转换为目标灰阶位数的目标灰阶电压后，驱动显示面板显示。
S40、直接根据当前帧的显示数据的默认灰阶电压，驱动显示面板显示。
本公开实施例提供的上述驱动方法，通过获取当前帧的显示数据和上一帧的显示数据，可以对当前帧的显示数据和上一帧的显示数据进行判分析，以判断当前帧的显示数据和上一帧的显示数据是否相同。在判断不相同时，可以将至少一个子像素的默认灰阶电压转换为目标灰阶位数的目标灰阶电压。 针对同一子像素，由于该子像素对应的目标电压差大于默认电压差，这样使得目标电压差产生的电场的强度可以大于默认电压差产生的电场的强度。在相同的充电时间内，强度较大的电场可以驱动液晶分子偏转的更快，以使液晶分子可以快速达到目标偏转角度，从而提高了液晶分子的响应速率。
在本公开实施例中，时序控制器300可以获取当前帧的显示数据和上一帧的显示数据；判断当前帧的显示数据和上一帧的显示数据是否相同；在判断当前帧的显示数据和上一帧的显示数据相同时，可以将当前帧的显示数据携带的默认灰阶位数的默认灰阶电压中，对应至少一个子像素的默认灰阶电压转换为目标灰阶位数的目标灰阶电压并输出。源极驱动电路可以接收时序控制器输出的目标灰阶电压，并根据接收的目标灰阶电压，驱动显示面板在当前帧中进行显示。在判断当前帧的显示数据和上一帧的显示数据不相同时，可以直接将当前帧的显示数据的默认灰阶电压输出。源极驱动电路可以接收时序控制器输出的默认灰阶电压，并根据接收的默认灰阶电压，驱动显示面板在当前帧中进行显示。
在本公开实施例中，可以使默认灰阶位数从6bit、8bit、10bit、12bit等进行选取。也可以使目标灰阶位数从6bit、8bit、10bit、12bit等进行选取。示例性地，由于灰阶位数越高，由最暗到最亮之间的不同亮度的层次级别会越多，所能够呈现的画面效果也就越细腻。基于此，可以使目标灰阶位数大于默认灰阶位数，从而可以使面板显示的更细腻。例如，默认灰阶位数为6bit，目标灰阶位数为8bit或10bit或12bit。或者，默认灰阶位数为8bit，目标灰阶位数为10bit或12bit。或者，默认灰阶位数为10bit，目标灰阶位数为12bit。需要说明的是，本公开实施例中，当前帧的显示数据自身携带有其分辨率，该分辨率对应一个灰阶位数，该灰阶位数即是本公开实施例中的默认灰阶位数。
示例性地，在子像素的像素电极中输入的灰阶电压大于公共电极上的电压时，可以使子像素的极性为正极性，该灰阶电压对应的灰阶值可以作为正灰阶值。在子像素的像素电极中输入的灰阶电压小于公共电极上的电压时，可以使子像素的极性为负极性，该灰阶电压对应的灰阶值可以作为负灰阶值。 例如，公共电极上的电压可以为8.3V，以一个子像素为例，若在该子像素的像素电极中输入了8.3V～16V的灰阶电压，可以使该子像素处的液晶分子为正极性，则8.3V～16V的灰阶电压为对应正灰阶值的灰阶电压。若在该子像素的像素电极中输入了0.6V～8.3V的灰阶电压，可以使该子像素处的液晶分子为负极性，则0.6V～8.3V的灰阶电压为对应负灰阶值的灰阶电压。示例性地，以8bit的0～255灰阶为例，以0～+255代表正灰阶值，0～-255代表负灰阶值，若在子像素的像素电极中输入16V的灰阶电压时，该子像素可以对应+255的最大正灰阶值的亮度。若在子像素的像素电极中输入0.6V的灰阶电压时，该子像素可以对应-255的最大负灰阶值的亮度。也就是说，+255是正灰阶值中的最大值，-255是负灰阶值中的最大值。同理，在10bit中，0～+1023代表正灰阶值，0～-1023代表负灰阶值。在12bit中，0～+4095代表正灰阶值，0～-4095代表负灰阶值。
在本公开实施例中，默认灰阶位数的最大正灰阶值对应的默认灰阶电压V +mrmax和最大负灰阶值对应的默认灰阶电压V -mrmax之间具有默认灰阶电压差V +mrmax-V -mrmax。目标灰阶位数的最大正灰阶值对应的目标灰阶电压V +mbmax和最大负灰阶值对应的目标灰阶电压V -mbmax之间具有目标灰阶电压差V +mbmax-V -mbmax。其中，目标灰阶电压差V +mbmax-V -mbmax大于默认灰阶电压差V +mrmax-V -mrmax，即V +mbmax-V -mbmax>V +mrmax-V -mrmax。例如，以默认灰阶位数为8bit，目标灰阶位数为10bit为例，8bit中，最大正灰阶值对应的默认灰阶电压为+255灰阶值对应的默认灰阶电压V +255，最大负灰阶值对应的默认灰阶电压为-255灰阶值对应的默认灰阶电压V -255，V +255>V -255，则默认灰阶电压差为V +255-V -255。10bit中，最大正灰阶值对应的目标灰阶电压为+1023灰阶值对应的目标灰阶电压V +1023，最大负灰阶值对应的目标灰阶电压为-1023灰阶值对应的目标灰阶电压V -1023，V +1023>V -1023，则目标灰阶电压差为V +1023-V -1023。则可以有V +1023-V -1023>V +255-V -255。
在本公开实施例中，可以将最大负灰阶值对应的默认灰阶电压作为最大负灰阶值对应的目标灰阶电压。以及，将最大正灰阶值对应的默认灰阶电压 加上设定的补偿电压后作为最大正灰阶值对应的目标灰阶电压。示例性地，若最大负灰阶值对应的默认灰阶电压为0.6V，则最大负灰阶值对应的目标灰阶电压也可以为0.6V。若最大正灰阶值对应的默认灰阶电压为16V，设定的补偿电压为1.5V～4V，则最大正灰阶值对应的目标灰阶电压可以为17.5V～20V。例如，以最大正灰阶值对应的默认灰阶电压为16V为例，若设定的补偿电压为1.5V时，最大正灰阶值对应的目标灰阶电压可以为17.5V。若设定的补偿电压为2.6V时，最大正灰阶值对应的目标灰阶电压可以为18.6V。若设定的补偿电压为4V时，最大正灰阶值对应的目标灰阶电压可以为20V。
需要说明的是，将最大负灰阶值对应的默认灰阶电压作为最大负灰阶值对应的目标灰阶电压，是基于源极驱动电路中元器件的性能考虑的。若是，源极驱动电路中元器件的性能允许，也可以将最大负灰阶值对应的默认灰阶电压减去设定的负补偿电压后作为最大负灰阶值对应的目标灰阶电压。
基于显示面板的透过率的考虑，结合图5，图5示意出了透过率与灰阶值对应的灰阶电压之间的关系曲线。横坐标代表电压，纵坐标代表透过率。其中，曲线上小于公共电极上的电压Vcom的电压为负灰阶值对应的灰阶电压，曲线上大于公共电极上的电压Vcom的电压为正灰阶值对应的灰阶电压。V -mrmax代表最大负灰阶值对应的默认灰阶电压，V +mrmax代表最大正灰阶值对应的默认灰阶电压，在V +mrmax的基础上依次增加电压，得到Vod区间段的电压，将此电压输入到子像素中，得到的透过率与加载V +mrmax时的透过率之间满足显示需要(例如，满足误差允许范围)，则可以将Vod区间段的电压作为最大正灰阶值对应的灰阶电压。然而，从图5中可知，在Vod区间段中，透过率也会有一些下降，为了保持透过率下降的较少，以及保持最大正灰阶值对应的灰阶电压尽可能的选取的较合适，可以将V0对应的18.6V作为最大正灰阶值对应的灰阶电压。并且，基于源极驱动电路中的元器件的额定电压和额定电流的考虑，将18.6V作为最大正灰阶值对应的灰阶电压，可以使源极驱动电路的功耗不会增加过多，从而可以在源极驱动电路所能承受的范围内，实现最大正灰阶值的灰阶电压。
通常，公共电极上的电压可以是最大正灰阶值对应的灰阶电压和最大负灰阶值对应的灰阶电压之间的中间值。例如，最大正灰阶值对应的灰阶电压为16V，最大负灰阶值对应的灰阶电压为0.6V时，公共电极上的电压可以为(16V+0.6V)/2＝8.3V。在本公开实施例中，由于目标灰阶电压差大于默认灰阶电压差，则默认灰阶电压对应的公共电极上的电压与目标灰阶电压对应的公共电极上的电压是不同的。示例性地，默认灰阶电压对应的公共电极上的电压Vcom mrmax可以如下：Vcom mr＝(V +mrmax+V -mrmax)/2。目标灰阶电压对应的公共电极上的电压Vcom mb可以如下：Vcom mbmax＝(V +mbmax+V -mbmax)/2。
在本公开实施例中，针对同一子像素，子像素对应的默认灰阶电压与公共电极上的电压Vcom1之间具有默认电压差，子像素对应的目标灰阶电压与公共电极上的电压之间具有目标电压差，目标电压差大于默认电压差。示例性地，针对同一子像素，子像素对应正灰阶的默认灰阶电压V +mr与公共电极上的电压Vcom mr之间具有默认电压差V +mr-Vcom mr，子像素对应正灰阶的目标灰阶电压V +mb与公共电极上的电压Vcom mb之间具有目标电压差V +mb-Vcom mb，V +mb-Vcom mb>V +mr-Vcom mr。示例性地，针对同一子像素，子像素对应负灰阶的默认灰阶电压V -mr与公共电极上的电压Vcom mr之间具有默认电压差Vcom mr-V -mr，子像素对应负灰阶的目标灰阶电压V -mb与公共电极上的电压Vcom mb之间具有目标电压差Vcom mb-V -mb，Vcom mb-V -mb>Vcom mr-V -mr。
示例性地，补偿电压可以是在显示面板出厂前进行测试得到的。在得到该补偿电压后，可以将补偿电压存储在时序控制器中，以便在显示面板出厂后可以根据本公开中的方法直接使用。
在本公开实施例中，确定补偿电压的方法，如图6所示，可以包括如下步骤：
S01、以最大正灰阶值对应的初始灰阶电压以及最大负灰阶值对应的初始灰阶电压为基准，基于设定步进电压值，在本次调节中，提高设定显示面板对应最大正灰阶值的灰阶电压。
示例性地，设定步进电压值可以为0.1V，0.2V、0.5V等，其可以根据实 际应用中的需要进行确定，在此不作限定。
以最大负灰阶值对应的初始灰阶电压为0.6V，最大正灰阶值对应的初始灰阶电压为16V，设置的设定步进电压值为0.1V为例，上一次调节中，对应最大正灰阶值的灰阶电压为16.4V，则本次调节中，可以在16.4V的基础上加上0.1V，得到16.5V，将16.5V作为本次调节提高后的最大正灰阶值的灰阶电压。
S02、根据最大负灰阶值对应的初始灰阶电压和提高后的最大正灰阶值对应的灰阶电压，确定设定显示面板对应的公共电压。
示例性地，公共电极上的电压可以是最大正灰阶值对应的灰阶电压和最大负灰阶值对应的灰阶电压之间的中间值。例如，最大正灰阶值对应的灰阶电压为16.5V，最大负灰阶值对应的灰阶电压为0.6V时，公共电极上的电压可以为(16.5V+0.6V)/2＝8.55V。
S03、根据确定出的公共电压和提高后的最大正灰阶值对应的灰阶电压，驱动设定显示面板显示。
需要说明的是，由于不同型号的显示面板的规格不同，在某一型号的显示面板制备完成后，在出厂前，可以从该型号的显示面板中，抽取出1个、2个、3个或更多个显示面板，作为设定显示面板。
示例性地，在公共电极上输入8.55V，在设定显示面板中的各子像素的像素电极上输入16.5V，以驱动该设定显示面板进行显示。
S04、采集设定显示面板的子像素中，像素电极和公共电极之间的公共电压差。
示例性地，在公共电极上输入8.55V，在设定显示面板中的各子像素的像素电极上输入16.5V后，可以通过电压采集装置，采集像素电极和公共电极之间的公共电压差。
S05、判断公共电压差是否满足设定公共电压值范围。
需要说明的是，设定公共电压值范围可以为误差允许范围。当然，在实际应用中，由于不同规格的显示面板的要求不同，因此，设定公共电压值范 围可以根据实际应用的需要进行确定，在此不作限定。
示例性地，通过电压采集装置，采集到的像素电极和公共电极之间的公共电压差与设定公共电压值范围进行对比，以判断该电压差是否处于设定公共电压值范围内。若是，则说明该电压差是处于设定公共电压值范围内的，则可以执行步骤S06。若否，则说明该电压差并未处于设定公共电压值范围内，则可以执行步骤S07。
S06、将本次提高后的对应最大正灰阶值的灰阶电压与对应最大正灰阶值的初始灰阶电压之间的差值作为补偿电压。
示例性地，由于对应最大正灰阶值的初始灰阶电压为16V，本次提高后的对应最大正灰阶值的灰阶电压为16.4V，则可以将0.5V作为补偿电压存储起来。
S07、若否，则进入下一次调节。
示例性地，在下一次调节中，可以在16.5V的基础上加上0.1V，得到16.6V，将16.6V作为下一次调节提高后的最大正灰阶值的灰阶电压。并，执行上述步骤S01之后的步骤，具体在此不作赘述。
在本公开实施例中，步骤30：将当前帧的显示数据携带的默认灰阶位数的默认灰阶电压中，对应至少一个子像素的默认灰阶电压转换为目标灰阶位数的目标灰阶电压后，驱动显示面板显示，具体可以包括如下步骤：针对每一个子像素，确定子像素在当前帧中默认灰阶电压对应的灰阶值与上一帧中默认灰阶电压对应的灰阶值之间的灰阶差值。在至少一个子像素对应的灰阶差值不小于灰阶差值阈值时，将子像素的默认灰阶电压转换为目标灰阶电压后，驱动显示面板显示。示例性地，以将要显示第n帧F(n)的画面为例，可以根据第n帧F(n)的显示数据，得到第n帧F(n)中对应每一个子像素的默认灰阶电压，以及该默认灰阶电压对应的灰阶值。以及，根据第n-1帧F(n-1)的显示数据，得到第n-1帧F(n-1)中对应每一个子像素的默认灰阶电压，以及该默认灰阶电压对应的灰阶值。以一个子像素为例，该子像素在第n帧F(n)对应的灰阶值与在第n+1帧F(n+1)对应的灰阶值之间的灰阶差值。同理可得 其余子像素对应的灰阶差值，在此不作赘述。在确定每一个子像素对应的灰阶差值后，可以将这些灰阶差值与灰阶差值阈值进行比较，若存在一个子像素对应的灰阶差值不小于该灰阶差值阈值，则说明灰阶跳变的较大，可能会存在残影的问题。基于此，可以将第n帧F(n)中，每一个子像素的默认灰阶电压转换为目标灰阶电压后，驱动显示面板显示。若不存在子像素对应的灰阶差值不小于该灰阶差值阈值，即所有子像素对应的灰阶差值小于该灰阶差值阈值，则说明灰阶跳变的较小，引起残影问题的几率较小。基于此，不用将第n帧F(n)中，每一个子像素的默认灰阶电压转换为目标灰阶电压，而是可以直接执行步骤S40。
在本公开实施例中，时序控制器可以存储有多个不同灰阶位数的关系表。在具体实施时，将子像素的默认灰阶电压转换为目标灰阶电压，具体可以包括：根据预先存储的多个不同灰阶位数的关系表，确定当前帧的显示数据携带的默认灰阶位数的各灰阶值在目标灰阶位数中对应的灰阶值。之后，从目标灰阶位数对应的灰阶值中确定目标灰阶值。之后，将目标灰阶值在目标灰阶位数中对应的灰阶电压，作为子像素的目标灰阶电压。其中，目标灰阶值大于子像素的默认灰阶电压对应的目标灰阶位数中的灰阶值。示例性地，目标灰阶值与子像素的默认灰阶电压对应的目标灰阶位数中的灰阶值之间相差设定灰阶数值。
在本公开实施例中，时序控制器存储了多个关系表，关系表包括：不同灰阶位数中各灰阶值的对应关系。例如，时序控制器存储了：表一(8bit与12bit的灰阶值对应关系)所示的关系表，表二(10bit与12bit的灰阶值对应关系)所示的关系表，表三(8bit与10bit的灰阶值对应关系)所示的关系表。当然，表一至表三仅是示例，时序控制器还可以存储其他灰阶位数的灰阶值对应的关系表，在此不作限定。
结合表一所示，例如，以8bit中的2灰阶为例，8bit中2灰阶对应12bit中8灰阶。即8bit中2灰阶的灰阶电压与公共电极上的电压之间的电压差与12bit中8灰阶的灰阶电压与公共电极上的电压之间的电压差相同。例如，以 8bit中的255灰阶为例，8bit中255灰阶对应12bit中4066灰阶。即8bit中255灰阶的灰阶电压与公共电极上的电压之间的电压差与12bit中4066灰阶的灰阶电压与公共电极上的电压之间的电压差相同。其余同理，在此不作赘述。

表四
在本公开实施例中，如图7所示，时序控制器300可以包括精确色彩处理(Accurate Color Capture，ACC)单元以及帧(Fram)驱动单元。其中，ACC单元可以获取当前帧的显示数据和上一帧的显示数据。并判断当前帧的显示数据和上一帧的显示数据是否相同。在判断当前帧的显示数据和上一帧的显示数据不相同时，针对每一个子像素，确定子像素在当前帧中默认灰阶电压对应的灰阶值与上一帧中默认灰阶电压对应的灰阶值之间的灰阶差值。在至少一个子像素对应的灰阶差值不小于灰阶差值阈值时，确定要转换为的目标灰阶位数。帧(Fram)驱动单元可以存储有多个不同灰阶位数的关系表，并根据默认灰阶位数和目标灰阶位数，以及根据存储的多个关系表中的默认灰阶位数和目标灰阶位数对应的关系表，确定当前帧的显示数据携带的默认灰阶位数的各灰阶值在目标灰阶位数中对应的灰阶值。之后，将目标灰阶值在目标灰阶位数中对应的灰阶电压，作为子像素的目标灰阶电压进行输出。源极驱动电路120可以包括数据解码单元、数模转换器、数据输出单元。其中，数据解码单元可以接收帧(Fram)驱动单元输出的目标灰阶电压，并将 接收到的目标灰阶电压进行解码后，输出给数模转换器。由于解码后的目标灰阶电压是数字信号，数模转换器将数字信号的目标灰阶电压转换为模拟信号的伽马电压并输出给数据输出单元。数据输出单元接收转换后的伽马电压，根据接口协议将该伽马电压传输给显示面板中的数据线，以对子像素充电。
以及，在判断当前帧的显示数据和上一帧的显示数据相同时，直接将当前帧的显示数据的默认灰阶电压输出给源极驱动电路。数据解码单元可以接收默认灰阶电压，并将接收到的默认灰阶电压进行解码后，输出给数模转换器。由于解码后的默认灰阶电压是数字信号，数模转换器将数字信号的默认灰阶电压转换为模拟信号的伽马电压并输出给数据输出单元。数据输出单元接收转换后的伽马电压，根据接口协议将该伽马电压传输给显示面板中的数据线，以对子像素充电。
下面结合图4a与图4b，以第n-1帧至第n+2帧F(n-1)～F(n+2)为例，对本公开实施例中的驱动方法进行说明。需要说明的是，本实施例中是为了更好的解释本公开，但不限制本公开。图4a与图4b中，L0代表灰阶值0，L1023代表正灰阶值1023，L4018代表正灰阶值4018。S20代表本公开实施例中灰阶的跳变曲线。S11代表现有技术中对显示面板中的子像素输入L1023灰阶对应的灰阶电压时，子像素充入的实际电压曲线。S12(实线)代表本公开实施例中对显示面板中的子像素输入L4018灰阶对应的灰阶电压时，子像素充入的实际电压曲线。S13代表本公开实施例中对显示面板中的子像素输入L4018灰阶对应的灰阶电压时，子像素充入的电压的趋势曲线。
下面以正灰阶值为例，负灰阶值同理，在此不作赘述。
以默认灰阶位数为10bit，目标灰阶位数为12bit为例。
在将要显示第n帧F(n)的画面时，可以将第n帧F(n)作为当前帧，将第n-1帧F(n-1)作为上一帧，这样可以获取到第n帧F(n)的显示数据和第n-1帧F(n-1)的显示数据。
将第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据中，对应同一子像素的显示数据进行比较，以将每一个子像素对应的显示数据均比较完。若 每一个子像素中，有部分子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是相同的，其余部分子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是不相同的。或者，全部子像素对应的第n帧F(n)的显示数据与第n-1帧F(n-1)的显示数据是不相同的。则说明第n帧F(n)将要显示的画面和第n-1帧F(n-1)已经显示的画面是不相同的。也就是说，第n帧F(n)和第n-1帧F(n-1)显示的画面进行了切换，即显示的是动态画面。此时，其余部分子像素对应灰阶进行了跳变。
根据第n帧F(n)的显示数据，得到第n帧F(n)中对应每一个子像素的默认灰阶电压，以及该默认灰阶电压对应的灰阶值。以及，根据第n-1帧F(n-1)的显示数据，得到第n-1帧F(n-1)中对应每一个子像素的默认灰阶电压，以及该默认灰阶电压对应的灰阶值。以一个子像素为例，该子像素在第n帧F(n)对应的灰阶值与在第n+1帧F(n+1)对应的灰阶值之间的灰阶差值。同理可得其余子像素对应的灰阶差值，在此不作赘述。
在确定每一个子像素对应的灰阶差值后，可以将这些灰阶差值与灰阶差值阈值进行比较，若存在一个子像素对应的灰阶差值不小于该灰阶差值阈值，则说明灰阶跳变的较大，可能会存在残影的问题。基于此，可以根据第n帧F(n)的显示数据，确定出第n帧F(n)的默认灰阶位数为10bit，以及要转换为的目标灰阶位数为12bit。这样可以根据存储的关系表二，确定出10bit中各灰阶值对应的12bit的灰阶值。需要说明的是，以10bit中的2灰阶为例，10bit中2灰阶对应12bit中4灰阶。即10bit中2灰阶的灰阶电压与公共电极上的电压之间的电压差与12bit中4灰阶的灰阶电压与公共电极上的电压之间的电压差相同。以10bit中的1023灰阶为例，10bit中1023灰阶对应12bit中4016灰阶。即10bit中1023灰阶的灰阶电压与公共电极上的电压之间的电压差与12bit中4016灰阶的灰阶电压与公共电极上的电压之间的电压差相同。也就是说，本公开中，若此时对显示面板中的子像素输入表二中4016灰阶对应的灰阶电压时，该显示面板实现的亮度，可以与现有技术中对显示面板中的子像素输入4096灰阶对应的灰阶电压所显示的亮度是相同的。
基于目标灰阶值大于子像素的默认灰阶电压对应的目标灰阶位数中的灰阶值，以及目标灰阶值与子像素的默认灰阶电压对应的目标灰阶位数中的灰阶值之间相差设定灰阶数值的考虑，可以从目标灰阶位数对应的灰阶值中确定目标灰阶值。例如，设定灰阶数值可以为2，以10bit中的1023灰阶为例，10bit中1023灰阶对应12bit中4016灰阶。可以将12bit中大于4016灰阶的其余灰阶值作为备选的目标灰阶值。又由于需要目标灰阶值与4016灰阶之间相差2，则可以将12bit中的4018灰阶值作为目标灰阶值。或者，设定灰阶数值可以为1，以10bit中的1023灰阶为例，10bit中1023灰阶对应12bit中4016灰阶。可以将12bit中大于4016灰阶的其余灰阶值作为备选的目标灰阶值。又由于需要目标灰阶值与4016灰阶之间相差1，则可以将12bit中的4017灰阶值作为目标灰阶值。当然，在实际应用中，设定灰阶数值可以根据实际应用的需求进行确定，在此不作限定。
将目标灰阶值在目标灰阶位数中对应的灰阶电压，作为子像素的目标灰阶电压。从而可以得到第n帧F(n)将要输入各个子像素中的目标灰阶电压。将第n帧F(n)将要输入各个子像素中的目标灰阶电压依次进行解码、数模转换后得到伽马电压，根据接口协议将该伽马电压传输给显示面板中的数据线，以对子像素充电。
在将要显示第n+1帧F(n+1)的画面时，可以将第n+1帧F(n+1)的显示数据与第n帧F(n)的显示数据中，对应同一子像素的显示数据进行比较，以将每一个子像素对应的显示数据均比较完。若每一个子像素中，同一子像素对应的第n帧F(n)的显示数据与第n+1帧F(n+1)的显示数据是相同的，则说明第n帧F(n)将要显示的画面和第n+1帧F(n+1)已经显示的画面是相同的。也就是说，第n帧F(n)和第n+1帧F(n+1)显示的画面未进行切换，即显示的是静态画面。此时，子像素对应灰阶不跳变，从而不用进行灰阶位数对应的灰阶电压的转换。则可以直接根据当前帧的显示数据的默认灰阶电压，以驱动显示面板显示。例如，输入10bit中1023灰阶对应的灰阶电压。
在将要显示第n+2帧F(n+2)的画面时，可以将第n+2帧F(n+2)的显示数 据与第n帧F(n)的显示数据中，对应同一子像素的显示数据进行比较，以将每一个子像素对应的显示数据均比较完。若每一个子像素中，同一子像素对应的第n帧F(n)的显示数据与第n+2帧F(n+2)的显示数据是相同的，则说明第n帧F(n)将要显示的画面和第n+2帧F(n+2)已经显示的画面是相同的。也就是说，第n帧F(n)和第n+2帧F(n+2)显示的画面未进行切换，即显示的是静态画面。此时，子像素对应灰阶不跳变，从而不用进行灰阶位数对应的灰阶电压的转换。则可以直接根据当前帧的显示数据的默认灰阶电压，以驱动显示面板显示。例如，输入10bit中1023灰阶对应的灰阶电压。
