参见图2所示，每个子像素SPX中可以包括晶体管01和像素电极02。其中，一行子像素SPX对应一条栅线，一列子像素SPX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。
结合图1至图3c所示，非显示区BB可以包括栅极驱动电路110以及源极驱动电路120。其中，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。示例性地，源极驱动电路120可以设置为2个，其中一个源极驱动电路120连接一半数量的数据线，另一个源极驱动电路120连接另一半数量的数据线。当然，源极驱动电路120也可以设置3个、4个、或更多个，其可以根据实际应用的需求进行设计确定，在此不作限定。
在本公开一些实施例中，如图3a与图3b所示，示意出了时序控制器200与显示面板之间的连接关系。其中，300代表系统控制器300，200代表时序控制器200，210代表能够传输显示数据的印刷电路板(Printed Circuit Board，PCB)(例如XPCB)，220代表覆晶薄膜(Chip On Film，COF)，120代表源极驱动电路，240代表时序控制器200所在的时序电路板。示例性地，系统控制器300可以接收一个显示帧的待显示图像的显示数据，然后将该显示数据发送给时序控制器200。时序控制器200可以通过电平转换(Level Shift)电路向栅极驱动电路110输入时钟控制信号，以使栅极驱动电路110对栅线输出栅极扫描信号，从而驱动栅线GA1、GA2、GA3、GA4。以及，时序控制器200还可以将接收到的显示数据进行相应处理，并在进行相应处理后发送给源极驱动电路120。源极驱动电路120可以根据接收到的显示数据向数据线DA1、DA2、DA3输入数据电压，从而对子像素SPX充电，使子像素SPX输入相应的数据电压，实现该显示帧的画面显示功能。示例性地，时序控制器200可以通过PCB 210以及COF 220，将显示数据输入到源极驱动电路120中。源极驱动电路120再根据显示数据对显示面板中的数据线加载数据电压。
示例性地，系统控制器300可以设置为系统级芯片(System on Chip，SOC)。当然，在实际应用中，可以根据实际应用的需求确定系统控制器300的实施 方式，在此不作限定。
需要说明的是，本公开实施例中的显示面板可以时钟为液晶显示面板。示例性地，液晶显示面板一般包括对盒的阵列基板和对向基板，以及封装在阵列基板和对向基板之间的液晶分子。在显示画面时，由于加载在各子像素SPX的像素电极上的数据电压和公共电极上的公共电极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SPX的透过率不同，以使子像素SPX实现不同灰阶的亮度，进而实现画面显示。
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。
示例性地，以一个子像素SPX为例，Vcom代表公共电极电压。其中，在该子像素SPX的像素电极中输入的数据电压大于公共电极电压Vcom时，可以使该子像素SPX处的液晶分子为正极性，则该子像素SPX中的数据电压对应的极性为正极性。在子像素SPX的像素电极中输入的数据电压小于公共电极电压Vcom时，可以使该子像素SPX处的液晶分子为负极性，则该子像素SPX中的数据电压对应的极性为负极性。例如，公共电极电压可以为8.3V，若在该子像素SPX的像素电极中输入了8.3V～16V的数据电压，可以使该子像素SPX处的液晶分子为正极性，则8.3V～16V的数据电压为对应正极性的数据电压。若在该子像素SPX的像素电极中输入了0.6V～8.3V的数据电压， 可以使该子像素SPX处的液晶分子为负极性，则0.6V～8.3V的数据电压为对应负极性的数据电压。示例性地，以8bit的0～255灰阶为例，若在子像素SPX的像素电极中输入16V的数据电压时，该子像素SPX可以对应正极性的最大灰阶值的亮度。若在子像素SPX的像素电极中输入0.6V的数据电压时，该子像素SPX可以对应负极性的最大灰阶值的亮度。
通常，响应时间是液晶显示面板特有的一个性能指标。所谓响应时间，是指液晶显示面板各子像素对输入的数据电压的反应速度，即子像素由暗转亮或由亮转暗所需要的时间。响应时间越短则使用者在看动态画面时越不会有拖尾的感觉。相比正性液晶，负性液晶具有更高的透过率特性，可显著提高液晶显示面板的亮度、清晰度以及对比度，从而达到画质的整体提升。但负性液晶也具有天生缺点，如旋转粘度高，导致同等条件下负性液晶响应时间不足，播放动态画面容易出现拖尾不良，如图4所示。结合图4所示，以灰阶位数为8bit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为第一个显示帧的画面中数字8所在的位置，W2为第二个显示帧的画面中数字8所在的位置，W3为第三个显示帧的画面中数字8所在的位置。通过图4可知，在第三个显示帧中显示W3对应的数字8时，W1对应的数字8和W2对应的数字8还会出现一些残留影像，从而形成了拖尾。
针对旋转粘度高导致的拖尾不良，可通过电路过驱动(Over Drive，OD)进行优化。然而，由于负性液晶的旋转速度受温度影响较大，温度越低，偏转速度越慢，导致在采用常温下调试好的OD查找表驱动液晶显示面板显示画面时，若液晶显示面板的温度略微升高，便会出现因过度过驱导致的动态画面反色不良。因此温度对于响应时间的影响仍不容忽视。
为了改善温度对应于相应时间的影响，本公开实施例提供了显示面板的驱动方法，可以通过获取显示面板的当前温度，再根据获取到的当前温度以及预先存储的设定温度对应的初始过驱动查找表，计算得到当前温度对应的新的当前过驱动查找表。也就是说，当前灰阶值是根据当前温度和初始灰阶 值计算得到的，使得当前过驱动查找表和初始过驱动查找表是不同的。从而可以根据显示面板的当前温度，来动态调整过驱动查找表，以通过调整后的当前过驱动查找表驱动显示面板显示，可以改善动态画面的反色不良的问题。这样还可以不用存储过多数量的初始过驱动查找表，从而可以降低存储所占用的空间，以及降低实际运行过程中的读取时间，提高读取速度。
结合图5所示，本公开实施例提供的显示面板的驱动方法，可以包括如下步骤：
S100、获取显示面板的当前温度。
在本公开一些实施例中，如图3a所示，显示装置还可以包括温度采集器500。该温度采集器500可以检测显示面板的温度。示例性地，温度采集器500可以在每经过设定时间后进行检测显示面板的温度的工作。例如，温度采集器500可以在每经过10min、30min、1h、10h或24h等时间后进行检测显示面板的温度的工作。
示例性地，温度采集器500可以设置于显示面板的非显示区BB中。这样可以避免温度采集器500占用显示区的面积，以及避免温度采集器500对显示区的显示效果造成影响。示例性地，温度采集器500才设置在显示面板的对向基板上，并且设置在对向基板与背光模组之间。这样可以进一步不用占用显示区的面积，可选的，温度采集器也可以设置在阵列基板和对向基板之间。例如对于液晶显示而言，温度采集器可以设置在阵列基板和对向基板形成的液晶盒内，例如可以设置在阵列基板靠近对向基板的一侧上，在此不做限定。
在本公开一些实施例中，时序控制器200可以直接从温度采集器500中采集温度采集器500检测到的显示面板的温度，并根据采集到的温度获取当前温度。示例性地，结合图3a所示，这样可以使温度采集器500检测到的显示面板的温度直接传递给时序控制器200，以使时序控制器200可以根据接收到的温度获取当前温度。这样可以使时序控制器200将该温度采集器500检测到的显示面板的温度，直接作为获取到的当前温度。这样可以在常规的COF 220及PCB 210上增加温控反馈引脚即可实现。
在本公开一些实施例中，系统控制器300可以直接从温度采集器500中采集温度采集器500检测到的显示面板的温度，并将采集到的温度发送给时序控制器200。时序控制器200根据接收到的温度获取当前温度。示例性地，结合图3b所示，可以采用信号接口走线(例如，通用型输入输出接口(General-Purpose Input/Output Ports，GPIO)走线)将显示面板100与系统控制器300连接起来。并将温度采集器500的引线连接至该信号接口走线上。这样可以使温度采集器500检测到的显示面板的温度先传递至系统控制器300，以使系统控制器300采集到该温度采集器500检测到的显示面板的温度。之后，系统控制器300再将采集到的温度发送给时序控制器200，以使时序控制器200可以根据接收到的温度获取当前温度。这样无需变更常规的COF 220及PCB 210设计，无需在COF 220和PCB 210上增加冗余的引脚，而是需要时序控制器200输入端口增加一个信号引脚即可实现。
在本公开一些实施例中，如图3a与图3b所示，可以将温度采集器500设置为一个，则当前温度为温度采集器500检测到的温度。这样可以使时序控制器200将接收到的温度，直接作为当前温度即可。这样可以降低成本，降低计算量以及降低温度采集器500占用过多的非显示区的空间。
在本公开一些实施例中，如图3c所示，在温度采集器500设置为至少两个时，可以将温度采集器500分散设置于非显示区中。示例性地，可以将温度采集器500的位置平均分布于显示面板的四周，具体位置和个数可视实际显示面板的而定。这样可以降低显示面板的干涉影响。客观来说，温度传感器的数量越多，实际监测环境温度越准确，但附加的元器件的变更会增多，例如，在COF和PCB上所需额外增加的温控反馈引脚也会增多。
在本公开一些实施例中，在温度采集器500设置为至少两个时，当前温度为各温度采集器500检测到的温度的平均值。这样可以使时序控制器200接收到每一个温度传输器的温度后，将这些温度进行计算确定出平均值，即可得到当前温度。
在本公开一些实施例中，温度采集器500可以包括：温度传感器和热敏电阻中的至少一个。示例性地，可以将温度采集器500设置为温度传感器。结合图3a所示，这样可以通过温度传感器将显示面板的温度转换为电信号(例如，电压信号或电流信号)，该电信号依次COF 220、以及PCB 210传递至时序控制器200中。其中，COF 220和PCB 210上分别预留用于传输该电信号的温控反馈引脚。或者，也可以将温度采集器500设置为热敏电阻。结合图3a所示，这样可以通过热敏电阻将显示面板的温度转换为电信号(例如，电压信号或电流信号)，该电信号依次通过COF 220、以及PCB 210传递至时序控制器200中。其中，COF 220和PCB 210上分别预留用于传输该电信号的温控反馈引脚。
需要说明的是，温度采集器500的数量、位置以及具体实施方式，可以根据实际应用的需求进行确定，在此不作限定。
S200、根据当前温度以及预先存储的设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表。
在本公开一些实施例中，可以将设定温度设置为多个。示例性地，设定温度设置为M个，则预先存储了M个初始过驱动查找表，且一个设定温度对应一个初始过驱动查找表。其中，M为整数且M≥2。例如，可以使M＝2，这样可以使设定温度设置为两个：设定温度TL和设定温度TH。且TL<TH。则设定温度TL对应一个初始过驱动查找表LUTL，设定温度TH对应另一个初始过驱动查找表LUTH。示例性地，可以将设定温度TL和设定温度TH分别设定为温度的下限和上限。例如，在显示面板未出厂前，对显示面板工作时的温度进行测试，可以得到显示面板的大致温度范围区间，这样将得到的温度范围区间的最小值设定为设定温度TL，将得到的温度范围区间的最大值设定为设定温度TH。例如，若得到的温度范围区间为25℃～40℃，则可以将TL＝25℃，TH＝40℃。当然，在实际应用中，可以根据实际应用的需求确定TL和TH的具体数值，在此不作限定。
在本公开一些实施例中，如图3a所示，显示装置还可以包括：存储器250。 该存储器250可以存储设定温度对应的初始过驱动查找表。例如，以设定温度为两个：设定温度TL和设定温度TH为例，存储器250可以存储设定温度TL对应的初始过驱动查找表LUTL，以及设定温度TH对应的初始过驱动查找表LUTH。示例性地，存储器250可以包括：带电可擦可编程只读存储器250(Electrically Erasable Programmable read only memory，EEPROM)和闪存(Flash)中至少一种。示例性地，存储器250可以设置在时序电路板上240，这样可以将存储器250与时序控制器200设置的较近，进一步降低信号传输时间。
示例性地，初始过驱动查找表可以包括：多个不同的第一灰阶值、多个不同的第二灰阶值、以及与任一第一灰阶值和任一第二灰阶值对应的初始灰阶值。示例性地，初始过驱动查找表具有对应的灰阶位数，即初始过驱动查找表中的第一灰阶值、第二灰阶值以及初始灰阶值具有对应的灰阶位数。例如，初始过驱动查找表对应的灰阶位数为8bit，则第一灰阶值、第二灰阶值以及初始灰阶值对应的灰阶位数可以为8bit，例如，初始过驱动查找表中的第一灰阶值可以为8bit中的0～255灰阶值中的所有灰阶值，第二灰阶值可以为8bit中的0～255灰阶值中的所有灰阶值。或者，初始过驱动查找表中的第一灰阶值可以为8bit中的0～255灰阶值中的部分灰阶值，第二灰阶值可以为8bit中的0～255灰阶值中的部分灰阶值。
示例性地，如图6所示，图6示意出了本公开实施例中的设定温度TL对应的初始过驱动查找表LUTL，该初始过驱动查找表LUTL可以包括8bit中部分第一灰阶值和部分第二灰阶值，以及这些第一灰阶值和第二灰阶值对应的初始灰阶值。图6中的第一行中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第一灰阶值，第一列中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第二灰阶值，其余数值(如L1-1～L17-17)代表初始灰阶值。需要说明的是，图6中示意的第一灰阶值和第二灰阶值的具体数值仅是举例说明。在实际应用中，可以是根据实际应用的需求进行确 定的，在此不作限定。需要说明的是，第一灰阶值可以对应上一个显示帧中子像素的灰阶值，第二灰阶值可以对应当前显示帧中子像素的灰阶值。
示例性地，如图7所示，图7示意出了本公开实施例中的设定温度TH对应的初始过驱动查找表LUTH，该初始过驱动查找表LUTH可以包括8bit中部分第一灰阶值和部分第二灰阶值，以及这些第一灰阶值和第二灰阶值对应的初始灰阶值。图7中的第一行中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第一灰阶值，第一列中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第二灰阶值，其余数值(如H1-1～H17-17)代表初始灰阶值。需要说明的是，图7中示意的第一灰阶值和第二灰阶值的具体数值仅是举例说明。在实际应用中，可以是根据实际应用的需求进行确定的，在此不作限定。需要说明的是，第一灰阶值可以对应上一个显示帧中子像素的灰阶值，第二灰阶值可以对应当前显示帧中子像素的灰阶值。
示例性地，当前过驱动查找表可以包括：多个不同的第一灰阶值、多个不同的第二灰阶值、以及与任一第一灰阶值和任一第二灰阶值对应的当前灰阶值。示例性地，当前过驱动查找表具有对应的灰阶位数，即当前过驱动查找表中的第一灰阶值、第二灰阶值以及当前灰阶值具有对应的灰阶位数。例如，初始过驱动查找表对应的灰阶位数和当前过驱动查找表对应的灰阶位数可以设置为相同。例如，初始过驱动查找表对应的灰阶位数为8bit，则可以将当前过驱动查找表对应的灰阶位数也设置为8bit，即在当前过驱动查找表中，第一灰阶值、第二灰阶值以及当前灰阶值对应的灰阶位数可以为8bit，例如，当前过驱动查找表中的第一灰阶值可以为8bit中的0～255灰阶值中的所有灰阶值，第二灰阶值可以为8bit中的0～255灰阶值中的所有灰阶值。或者，当前过驱动查找表中的第一灰阶值可以为8bit中的0～255灰阶值中的部分灰阶值，第二灰阶值可以为8bit中的0～255灰阶值中的部分灰阶值。
示例性地，如图8所示，图8示意出了本公开实施例中的当前温度TD对应的当前过驱动查找表LUTD，该当前过驱动查找表LUTD可以包括8bit中 部分第一灰阶值和部分第二灰阶值，以及这些第一灰阶值和第二灰阶值对应计算得到的当前灰阶值。图8中的第一行中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第一灰阶值，第一列中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第二灰阶值，其余数值(如D1-1～D17-17)代表当前灰阶值。需要说明的是，图8中示意的第一灰阶值和第二灰阶值的具体数值仅是举例说明。在实际应用中，可以是根据实际应用的需求进行确定的，在此不作限定。需要说明的是，第一灰阶值可以对应上一个显示帧中子像素的灰阶值，第二灰阶值可以对应当前显示帧中子像素的灰阶值。
在本公开一些实施例中，当前温度TD对应的当前过驱动查找表LUTD可以存储在时序控制器中。或者，当前温度TD对应的当前过驱动查找表LUTD也可以存储在存储器中，在此不作限定。这样在后面根据当前过驱动查找表，可以从时序控制器中或存储器中调用存储的当前过驱动查找表LUTD，以驱动显示面板中的子像素充入相应的数据电压。
在本公开一些实施例中，也可以使实时计算当前过驱动查找表LUTD，这样可以不存储计算出的当前温度TD对应的当前过驱动查找表LUTD，可以节省存储空间。这样在后面根据当前过驱动查找表，可以直接通过实时计算出的当前过驱动查找表LUTD，以驱动显示面板中的子像素充入相应的数据电压。
在本公开一些实施例中，时序控制器可以根据当前温度以及预先存储的设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表。示例性地，根据当前温度以及预先存储的设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表，可以包括：首先，根据当前温度，调用M个设定温度对应的初始过驱动查找表中第m个设定温度对应的初始过驱动查找表和第m+1个设定温度对应的初始过驱动查找表。之后，再根据当前温度，第m个设定温度对应的初始过驱动查找表以及第m+1 个设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表中的各当前灰阶值。示例性地，第m个设定温度小于当前温度，第m+1个设定温度大于当前温度；m为整数，且1≤m≤M-1。例如，第m个设定温度为小于且最接近当前温度的设定温度。第m+1个设定温度为大于且最接近当前温度的设定温度。例如，M＝2时，第一个设定温度即为小于且最接近当前温度的设定温度，第二个设定温度即为大于且最接近当前温度的设定温度。M＝3时，若当前温度大于第一设定温度且小于第二设定温度，则第一个设定温度即为小于且最接近当前温度的设定温度，第二个设定温度即为大于且最接近当前温度的设定温度。若当前温度大于第二设定温度且小于第三设定温度，则第二个设定温度即为小于且最接近当前温度的设定温度，第三个设定温度即为大于且最接近当前温度的设定温度。
在本公开一些实施例中，根据当前温度，第m个设定温度对应的初始过驱动查找表以及第m+1个设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表中的各当前灰阶值，可以包括：首先，基于同一第一灰阶值和同一第二灰阶值的原则，即选定一个第一灰阶值和一个第二灰阶值，以确定第m个设定温度对应的初始过驱动查找表中的第一初始灰阶值，以及第m+1个设定温度对应的初始过驱动查找表中的第二初始灰阶值。之后，根据当前温度、第m个设定温度、第m+1个设定温度、第一初始灰阶值以及第二初始灰阶值，确定当前过驱动查找表中与第一初始灰阶值和第二初始灰阶值对应的当前灰阶值。例如，根据当前温度、第m个设定温度、第m+1个设定温度、第一初始灰阶值以及第二初始灰阶值，确定当前过驱动查找表中与第一初始灰阶值和第二初始灰阶值对应的当前灰阶值，可以包括：首先，根据第m个设定温度、第m+1个设定温度、第一初始灰阶值以及第二初始灰阶值，拟合得到与温度相关的计算公式：D a-b＝A a-bt 2+B a-bt+C a-b。之后，根据当前温度和计算公式，确定当前过驱动查找表中与第一初始灰阶值和第二初始灰阶值对应的当前灰阶值。其中，D a-b代表基于同一第一灰阶值和同一第二灰阶值的原则确定出的第一初始灰阶值(即根据选定出的一个第一灰阶 值和一个第二灰阶值，确定出的第一初始灰阶值)以及第二初始灰阶值(即根据选定出的一个第一灰阶值和一个第二灰阶值，确定出的第二初始灰阶值)对应的当前灰阶值，t代表当前温度，A a-b、B a-b以及C a-b分别代表基于同一第一灰阶值和同一第二灰阶值的原则确定出的第一初始灰阶值以及第二初始灰阶值对应的拟合参数，a代表基于同一第一灰阶值和同一第二灰阶值的原则确定出的第一初始灰阶值(即根据选定出的一个第一灰阶值和一个第二灰阶值，确定出的第一初始灰阶值)，b代表基于同一第一灰阶值和同一第二灰阶值的原则确定出的第二初始灰阶值(即根据选定出的一个第一灰阶值和一个第二灰阶值，确定出的第二初始灰阶值)。
需要说明的是，上述拟合得到的与温度相关的计算公式：D a-b＝A a-bt 2+B a-bt+C a-b，仅是一种示意，在实际应用中，还可以根据上述条件拟合得到其他可适用的公式。因此，在实际应用中，可以根据实际应用环境的需求根据上述条件拟合得到所适用的公式，具体在此不作限定。
在本公开一些实施例中，根据当前温度和计算公式，确定当前过驱动查找表中与第一初始灰阶值和第二初始灰阶值对应的当前灰阶值，可以包括：首先，根据当前温度和计算公式：D a-b＝A a-bt 2+B a-bt+C a-b，确定当前过驱动查找表中与第一初始灰阶值和第二初始灰阶值对应的中间灰阶值。其中，在确定中间灰阶值不小于最小端点灰阶值且不大于最大端点灰阶值时，可以将中间灰阶值确定为当前灰阶值。在确定中间灰阶值小于最小端点灰阶值时，可以将最小端点灰阶值确定为当前灰阶值。以及，在确定中间灰阶值大于最大端点灰阶值时，可以将最大端点灰阶值确定为当前灰阶值。例如，以8bit为例，若根据D a-b＝A a-bt 2+B a-bt+C a-b计算得到D a-b＝127时，可以直接将127作为当前灰阶值写入当前过驱动查找表。若根据D a-b＝A a-bt 2+B a-bt+C a-b计算得到D a-b＝-3时，可以直接将0作为当前灰阶值写入当前过驱动查找表。若根据D a-b＝A a-bt 2+B a-bt+C a-b计算得到D a-b＝300时，可以直接将255作为当前灰阶值写入当前过驱动查找表。
下面以M＝2，当前温度为33℃为例，对本公开实施例提供的计算当前温 度对应的当前过驱动查找表的过程进行说明。存储器250存储了两个初始过驱动查找表：第一个设定温度TL(例如25℃)对应的初始过驱动查找表LUTL，第二个设定温度TH(例如40℃)对应的初始过驱动查找表LUTH。由于时序控制器200获取到的当前温度为33℃，则时序控制器200可以确定当前温度与第一个设定温度TL(例如25℃)和第二个设定温度TH(例如40℃)均不同，则时序控制器200可以从存储器250中调用初始过驱动查找表LUTL和初始过驱动查找表LUTH。时序控制器200可以根据选定的一个第一灰阶值和一个第二灰阶值，例如选定了第一灰阶值为0，第二灰阶值为128时，可以从初始过驱动查找表LUTL中确定出第一初始灰阶值为L9-1，以及从初始过驱动查找表LUTH中确定出第二初始灰阶值为H9-1。即公式中D a-b＝A a-bt 2+B a-bt+C a-b，a＝0，b＝128。则D ab为D 0-128，A a-b为A 0-128，B a-b为B 0-128，C a-b为C 0-128。即，D 0-128＝A 0-128t 2+B 0-128t+C 0-128。结合图10所示，时序控制器200可以根据第一个设定温度TL(例如25℃)、第二个设定温度TH(例如40℃)、第一初始灰阶值L9-1以及第二初始灰阶值H9-1，可以拟合得到与温度相关的曲线S 0-128，该曲线S 0-128的计算公式可以为：D 0-128＝A 0-128t 2+B 0-128t+C 0-128。将当前温度33℃，代入公式D 0-128＝A 0-128t 2+B 0-128t+C 0-128，可以计算得到第一灰阶值为0和第二灰阶值为128时对应的中间灰阶值D 0-128＝D9-1，在该中间灰阶值D 0-128＝D9-1不小于0且不大于255时，可以将D9-1确定为当前灰阶值写入当前过驱动查找表LUTD中。
以及，时序控制器200可以根据选定的一个第一灰阶值和一个第二灰阶值，例如选定了第一灰阶值为32，第二灰阶值为160时，可以从初始过驱动查找表LUTL中确定出第一初始灰阶值为L11-3，以及从初始过驱动查找表LUTH中确定出第二初始灰阶值为H11-3。即公式中D a-b＝A a-bt 2+B a-bt+C a-b，a＝32，b＝160。则D ab为D 32-160，A a-b为A 32-160，B a-b为B 32-160，C a-b为C 32-160。即，D 32-160＝A 32-160t 2+B 32-160t+C 32-160。结合图11所示，时序控制器200可以根据第一个设定温度TL(例如25℃)、第二个设定温度TH(例如40℃)、第一初始灰阶值L11-3以及第二初始灰阶值H11-3，可以拟合得到与温度相关的曲线S 32-160， 该曲线S 32-160的计算公式可以为：D 32-160＝A 32-160t 2+B 32-160t+C 32-160。将当前温度33℃，代入公式D 32-160＝A 32-160t 2+B 32-160t+C 32-160，可以计算得到第一灰阶值为32和第二灰阶值为160时对应的中间灰阶值D 32-160＝D11-3，在该中间灰阶值D 32-160＝D11-3不小于0且不大于255时，可以将D11-3确定为当前灰阶值写入当前过驱动查找表LUTD中。需要说明的是，图10与图11中，横坐标Tem代表时间，纵坐标GL代表灰阶值。并且，其余第一灰阶值和第二灰阶值对应的当前灰阶值的计算过程，与上述过程基本相同，可以此类推，在此不作赘述。
下面以M＝3，当前温度为33℃为例，对本公开实施例提供的计算当前温度对应的当前过驱动查找表的过程进行说明。存储器250存储了两个初始过驱动查找表：第一个设定温度TL(例如25℃)对应的初始过驱动查找表LUTL，第二个设定温度TZ(例如30℃)对应的初始过驱动查找表LUTZ，第三个设定温度TH(例如40℃)对应的初始过驱动查找表LUTH。示例性地，如图12所示，图12示意出了本公开实施例中的设定温度TZ对应的初始过驱动查找表LUTZ，该初始过驱动查找表LUTZ可以包括8bit中部分第一灰阶值和部分第二灰阶值，以及这些第一灰阶值和第二灰阶值对应的初始灰阶值。图12中的第一行中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第一灰阶值，第一列中的数值(如0、16、32、48、64、80、96、112、128、144、160、176、192、208、224、240、255)代表第二灰阶值，其余数值(如Z1-1～Z17-17)代表初始灰阶值。需要说明的是，图12中示意的第一灰阶值和第二灰阶值的具体数值仅是举例说明。在实际应用中，可以是根据实际应用的需求进行确定的，在此不作限定。需要说明的是，第一灰阶值可以对应上一个显示帧中子像素的灰阶值，第二灰阶值可以对应当前显示帧中子像素的灰阶值。
由于时序控制器200获取到的当前温度为33℃，则时序控制器200可以确定当前温度与第一个设定温度TL(例如25℃)、第二个设定温度TZ(例如30℃)以及第二个设定温度TH(例如40℃)均不同。则时序控制器200可以 从存储器250中调用当前温度最接近的且小于当前温度的第二个设定温度TZ对应的初始过驱动查找表LUTZ和当前温度最接近的且大于当前温度的第三个设定温度TH对应的初始过驱动查找表LUTH。时序控制器200可以根据选定的一个第一灰阶值和一个第二灰阶值，例如选定了第一灰阶值为0，第二灰阶值为128时，可以从初始过驱动查找表LUTZ中确定出第一初始灰阶值为Z9-1，以及从初始过驱动查找表LUTH中确定出第二初始灰阶值为H9-1。即公式中D a-b＝A a-bt 2+B a-bt+C a-b，a＝0，b＝128。则D ab为D 0-128，A a-b为A 0-128，B a-b为B 0-128，C a-b为C 0-128。即，D 0-128＝A 0-128t 2+B 0-128t+C 0-128。结合图13所示，时序控制器200可以根据第二个设定温度TZ(例如30℃)、第三个设定温度TH(例如40℃)、第一初始灰阶值Z9-1以及第二初始灰阶值H9-1，可以拟合得到与温度相关的曲线S 0-128，该曲线S 0-128的计算公式可以为：D 0-128＝A 0-128t 2+B 0-128t+C 0-128。将当前温度33℃，代入公式D 0-128＝A 0-128t 2+B 0-128t+C 0-128，可以计算得到第一灰阶值为0和第二灰阶值为128时对应的中间灰阶值D 0-128＝D9-1，在该中间灰阶值D 0-128＝D9-1不小于0且不大于255时，可以将D9-1确定为当前灰阶值写入当前过驱动查找表LUTD中。
以及，时序控制器200可以根据选定的一个第一灰阶值和一个第二灰阶值，例如选定了第一灰阶值为32，第二灰阶值为160时，可以从初始过驱动查找表LUTZ中确定出第一初始灰阶值为Z11-3，以及从初始过驱动查找表LUTH中确定出第二初始灰阶值为H11-3。即公式中D a-b＝A a-bt 2+B a-bt+C a-b，a＝32，b＝160。则D ab为D 32-160，A a-b为A 32-160，B a-b为B 32-160，C a-b为C 32-160。即，D 32-160＝A 32-160t 2+B 32-160t+C 32-160。结合图14所示，时序控制器200可以根据第二个设定温度TZ(例如30℃)、第三个设定温度TH(例如40℃)、第一初始灰阶值Z11-3以及第二初始灰阶值H11-3，可以拟合得到与温度相关的曲线S 32-160，该曲线S 32-160的计算公式可以为：D 32-160＝A 32-160t 2+B 32-160t+C 32-160。将当前温度33℃，代入公式D 32-160＝A 32-160t 2+B 32-160t+C 32-160，可以计算得到第一灰阶值为32和第二灰阶值为160时对应的中间灰阶值D 32-160＝D11-3，在该中间灰阶值D 32-160＝D11-3不小于0且不大于255时，可以将D11-3确定为当前灰阶值 写入当前过驱动查找表LUTD中。需要说明的是，图13与图14中，横坐标Tem代表时间，纵坐标GL代表灰阶值。并且，其余第一灰阶值和第二灰阶值对应的当前灰阶值的计算过程，与上述过程基本相同，可以以此类推，在此不作赘述。
需要说明的是，存储器250存储的初始过驱动查找表的数量可以设置为2个或3个，这样可以尽可能的降低初始过驱动查找表的数量，以节省存储空间。当然，初始过驱动查找表的数量也可以根据实际应用的需求进行确定，在此不作限定。
S300、根据当前过驱动查找表，驱动显示面板中的子像素充入相应的数据电压。
在本公开实施例中，步骤S300可以包括，在确定出当前过驱动查找表后的每一个显示帧中，根据当前过驱动查找表，驱动显示面板中的子像素充入相应的数据电压。例如，时序控制器200可以根据当前显示帧(如确定出当前过驱动查找表后的一个显示帧)的显示数据(该显示数据包括每一个子像素一一对应的携带有相应灰阶值的数据电压的数字电压形式)，确定出当前显示帧每一个子像素对应的灰阶值。根据上一个显示帧显示数据(该显示数据包括每一个子像素一一对应的携带有相应灰阶值的数据电压的数字电压形式)，确定出当前显示帧每一个子像素对应的灰阶值。根据当前显示帧和上一个显示帧中对应同一子像素的灰阶值，从当前过驱动查找表中确定出该子像素对应的当前灰阶值。时序控制器200可以将确定出来的当前灰阶值发送给源极驱动电路120，源极驱动电路120可以根据该当前灰阶值对该子像素连接的数据线加载对应当前灰阶值的数据电压，以使该子像素可以充入对应当前灰阶值的数据电压。
示例性地，从当前过驱动查找表中确定出该子像素对应的当前灰阶值，所使用的上一个显示帧的灰阶值可以为上一个显示帧的当前灰阶值。当然，从当前过驱动查找表中确定出该子像素对应的当前灰阶值，所使用的上一个显示帧的灰阶值可以为上一个显示帧的原始灰阶值。该原始灰阶值可以为接 收到的显示数据对应的灰阶值。
示例性地，从当前过驱动查找表中确定出该子像素对应的当前灰阶值，所使用的当前显示帧的灰阶值可以为当前显示帧的原始灰阶值。该原始灰阶值可以为接收到的显示数据对应的灰阶值。
示例性地，显示面板工作在连续的多个显示帧中，每个显示帧可以包括数据刷新阶段和空白时间(Blanking Time)阶段。结合图9所示，以显示帧F1和F2为例，显示帧F1和显示帧F2可以包括数据刷新阶段TS和空白时间(Blanking Time)阶段TB。并且，显示帧F2作为确定出当前过驱动查找表后的第一个显示帧。以数据线DA1连接的同一列中的，第一行中子像素A1、第二行中子像素A2、第三行中子像素A3以及第四行中子像素A4为例。若子像素A1在显示帧F1中的灰阶值为32，在显示帧F2中的灰阶值为128，从而可以从当前过驱动查找表中，找到子像素A1对应的当前灰阶值为D9-3。同理，可以找到子像素A2对应的当前灰阶值为D16-4，找到子像素A3对应的当前灰阶值为D12-6，找到子像素A4对应的当前灰阶值为D6-7。
并且，当前灰阶值为D9-3、D16-4、D12-6以及D6-7可以输入到源极驱动电路120中，在显示帧F2的数据刷新阶段TS，栅极驱动电路110对栅线GA1加载信号ga1，对栅线GA2加载信号ga2，对栅线GA3加载信号ga3，对栅线GA4加载信号ga4，在信号ga1～ga4中出现栅极开启电压(例如高电平对应的电压)时，可以控制对应的晶体管010导通。源极驱动电路120依次对数据线DA1加载对应当前灰阶值D9-3的数据电压VD9-3、对应当前灰阶值D16-4的数据电压VD16-4、对应当前灰阶值D12-6的数据电压VD12-6、以及对应当前灰阶值D6-7的数据电压VD6-7。示例性地，在信号ga1出现栅极开启电压时，可以控制第一行子像素中的晶体管01均导通，对数据线DA1加载相应的数据电压VD9-3，以使第一行子像素中的子像素A1的像素电极02输入数据电压VD9-3。在信号ga2出现栅极开启电压时，可以控制第二行子像素中的晶体管01均导通，对数据线DA1加载相应的数据电压VD16-4，以使第二行子像素中的子像素A2的像素电极02输入数据电压VD16-4。在信 号ga3出现栅极开启电压时，可以控制第三行子像素中的晶体管01均导通，对数据线DA1加载相应的数据电压VD12-6，以使第三行子像素中的子像素A3的像素电极02输入数据电压VD12-6。在信号ga4出现栅极开启电压时，可以控制第四行子像素中的晶体管01均导通，对数据线DA1加载相应的数据电压VD6-7，以使第四行子像素中的子像素A4的像素电极02输入数据电压VD6-7。其余行以此类推，在此不作赘述。以及，在空白时间(Blanking Time)阶段TB中，信号ga1～ga4均为低电平，每个子像素中的晶体管01均处于截止状态。并且，数据线DA1～DA3可以不加载电压，均处于浮接状态。
需要说明的是，在温度采集器500每一次进行检测显示面板的温度后，都会确定一次当前过驱动查找表。并且在确定出当前过驱动查找表后的每一个显示帧中，根据当前过驱动查找表，驱动显示面板中的子像素充入相应的数据电压。也就是说，若再次执行上述步骤S100～S200，确定出了新的当前过驱动查找表后，在确定出当前过驱动查找表后的每一个显示帧中，根据新的当前过驱动查找表，驱动显示面板中的子像素充入相应的数据电压。
在本公开一些实施例中，步骤S200：根据当前温度以及预先存储的设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表，可以包括：在当前温度与M个设定温度不同时，根据当前温度以及预先存储的设定温度对应的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表。这样由于当前温度与M个设定温度均不同，从而不能从存储的这些初始过驱动查找表中调取到对应当前温度的查找表，这样可以根据当前温度以及存储的初始过驱动查找表，计算得到当前温度对应的当前过驱动查找表，从而可以根据显示面板的当前温度，来动态调整过驱动查找表，以通过调整后的当前过驱动查找表驱动显示面板显示，可以改善动态画面的反色不良的问题。
在本公开一些实施例中，在当前温度与M个设定温度中的一个设定温度相同时，可以根据当前温度，调用M个设定温度中与当前温度相同的设定温度对应的初始过驱动查找表。并根据调用的初始过驱动查找表，驱动显示面 板中的子像素充入相应的数据电压。示例性地，以M＝2，当前温度为25℃为例，存储器250存储了两个初始过驱动查找表：第一个设定温度TL(例如25℃)对应的初始过驱动查找表LUTL，第二个设定温度TH(例如40℃)对应的初始过驱动查找表LUTH。则时序控制器200可以确定当前温度与第一个设定温度TL相同，可以从存储器250中调用初始过驱动查找表LUTL。这样可以在与当前温度相同的设定温度对应的初始过驱动查找表LUTL后的每一个显示帧中，根据调用初始过驱动查找表LUTL，驱动显示面板中的子像素充入相应的数据电压。
