Description

驱动方法、液晶显示面板和电子装置 技术领域
本申请涉及驱动方法、液晶显示面板和电子装置。
背景技术
液晶显示面板由于具有节能、重量轻、平板化、无辐射等等优点，已经广泛地应用于各种电子装置中用作显示器。
然而，目前在诸如移动电子设备的产品中，对产品功耗的要求越来越高，所以在作为显示器的液晶显示面板端，功耗节省是一种非常重要的功能。
为了节省功耗，在液晶显示面板中现在通用使用的方式是称为电荷共享(Charge Sharing)的方法。在进行电荷共享时，源极驱动电路通常是在每帧刷新时进行一次显示电压的极性变换。当接收到反转极性切换信号时，将液晶显示面板的所有源极短接到一起，将电荷共享。
然而，这样进行电荷共享虽然能使功耗降低，但是没有考虑到下一行的数据的需求。因此如果在极性没有切换的时候进行这样的电荷共享，则电压会被拉到公共电极的电压Vcom附近，然后再抬升(或者降低)到所需要的电压，会更加费。
为此，期望提供一种驱动方法、液晶显示面板和电子装置，其能够根据上一行和下一行之间的数据差异，选择性地在两个数据线之间进行电荷共享，从而进一步节省功耗。

具体实施方式
下面，将参考附图详细描述根据本申请实施例的驱动方法、液晶显示面板和电子装置。
根据本申请实施例的驱动方法可以应用于液晶显示面板中。
在描述根据本申请实施例的驱动方法、液晶显示面板和电子装置之前，首先参考图1简单描述液晶显示面板的结构以及电荷共享的原理。
如图1所示，通常液晶显示面板包括栅极驱动电路101、源极驱动电路102多条扫描线G1-Gn、多条数据线D1-Dm以及由该多条扫描线与多条数据线交叉形成的多个像素单元103、以及时序控制电路104。
多条扫描线G1-Gn连接至栅极驱动电路101，栅极驱动电路101通过多条扫描线G1-Gn为多个像素单元103提供栅极驱动信号。
多条数据线D1-Dm连接至源极驱动电路102，源极驱动电路102通过多 条数据线D1-Dm为多个像素单元提供显示信号。
每个像素单元103形成在该多条扫描线与多条数据线交叉处，并且例如包括一个开关晶体管104。该开关晶体管104的栅极连接扫描线以接收栅极驱动信号。该开关晶体管104的连接数据线以接收显示信号。该开关晶体管104的漏极连接液晶电容Clc以及保持电容器Chc。
时序控制电路104控制各个电路的操作时序。
如本领域技术人员熟知的，为了避免液晶显示面板中的液晶中的可移动离子造成直流残留的问题，需对每一个像素单元的液晶电容上的电压作极性反转，使得提供给像素单元的显示电压于前后两帧画面中极性相反。目前较普遍使用的极性反转的驱动方式包括帧反转、行反转、列反转、点反转以及Z反转(Z-invertion)。
因此，对于同一条数据线来说，其上所需输出的电压为正负极性交错，而对于每一像素单元的液晶电容来说，其充放电的功率消耗为0.5*f*Clc*V*V，其中，f是电压充放电的频率，V为充放电的电压，即显示电压，Clc为液晶电容。在采用极性反转驱动的液晶显示面板中，由于源极驱动电路需要在每帧刷新时进行一次显示电压的极性变换，因此需消耗较大的功耗。例如，对于诸如点反转、Z反转驱动的液晶显示面板，除了在每帧刷新时进行一次显示电压的极性变换，在每一帧时段内，每一扫描线被栅极驱动信号扫描时，源极驱动电路都要使对应每一条数据线的输出通道所提供的显示信号的电压极性变换一次，因此，所需要的功耗更大。
因此，现有技术中采用的节省功耗的方式就是所谓的电荷共享(Charge Sharing)。在采用电荷共享方法的液晶显示面板中，在每帧极性切换的时候，将液晶显示面板中的所有源极短接到一起，将电荷共享，从而拉到公共电极的电压Vcom附近。然后，将每行数据线的电压从Vcom再抬升(或者降低)到所需要的电压。
例如，如图1所示，通过额外提供的公共电极Vcom，在电荷共享时，将液晶显示面板中的所有源极短接到一起，实现电荷共享。
然而，这种做法的问题就在于简单地将所有源极短接到一起，而没有考虑每条数据线中上一行和下一行之间的数据差异，导致所需要的功耗更大。
另外，这样电荷共享方法只能在每帧极性切换的时候进行电荷切换，因 此在许多情况下并不能节省功耗。
考虑这种情况，做出了本申请的各个实施例。
<第一实施例>
下面将结合图2和图3详细描述根据本申请第一实施例的驱动方法。在本实施例中，将以Z反转作为例子进行描述。
图2是图示采用Z反转的液晶显示面板的电路图。如图2所示，假设从左到右依次排列红色、绿色、蓝色的多列子像素。相应地，与每列子像素对应地提供多条数据线(例如，m条，m为正整数)，交替地连接到不同行中的子像素。例如，对于第2列的数据线D2，其连接到第一行中的绿色子像素、第二行中的红色子像素、第三行中的绿色子像素、第四行中的红色子像素……。对于第3列的数据线D3，其连接到第一行中的蓝色子像素、第二行中的绿色子像素、第三行中的蓝色子像素、第四行中的绿色子像素……。诸如此类，每列数据线分别交替地连接到不同行中的子像素。此外，在该多条数据线上交替地提供正极性和负极性的显示信号。
在采用Z反转驱动的液晶显示面板中，对于每一条数据线来说，上一行的数据和下一行的数据差异不同。因此，如果简单地将所有数据线共同拉到公共电极的电压Vcom附近，然后再抬升(或者降低)到所需要的电压，可能会导致更多的功耗，而并不能节省功耗。
因此，如图3所示，根据本申请第一实施例的驱动方法应用于例如图2所示的采用Z反转的液晶显示面板中，所述液晶显示面板包括第一多条数据线(例如，m条，m为正整数)，所述方法包括：
步骤S301：将所述第一多条数据线分组为多个子组，每个子组包括第二多条数据线；
步骤S302：针对每个子组的第二多条数据线，确定每条数据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差；以及
步骤S303：根据确定的灰阶数差，在每个子组中的第二多条数据线之间选择性地进行电荷共享。
具体地，在步骤S301中，按照数据线排列的顺序，将m条数据线分为多个子组，每个子组包括第二多条数据线(例如，n条，n为正整数)。例如， 在图2所示的实施例中，以n为12条为例进行说明。需要注意的是，n不限于12条，例如还可以为8条、16条、20条、20条等等，只要n为4的倍数。
然后，在步骤S302中，针对每个子组的第二多条数据线，确定每条数据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差。
具体地，例如，对于图2所示的12条数据线，首先确定每条数据线的前一行的灰阶数，也就是说，确定每条数据线上的之前输出的显示信号电压。然后，确定每条数据线的下一行的灰阶数，也就是说，确定每条数据线上的即将输出的显示信号电压。然后，根据每条数据线上之前输出的显示信号电压和即将输出的显示信号电压，确定每条数据线上每次显示信号电压跳变的量，即，灰阶数差。
例如，可以按照下面的公式1确定灰阶数差：
Gn＝G″n-G'n    公式1
Gn表示第n条数据线上的数据跳过的灰阶数，Gn’表示第n条数据线上的数据的上一行的灰阶，Gn”第n条数据线上的数据的下一行的灰阶。
Gn、Gn’和Gn”都是带有“+”或“-”符号的。例如Gn＝-100-(+90)＝-190表示从正极性的90灰阶跳到负极性的100灰阶，此时灰阶数差是-190。例如，Gn＝100-(+90)从正极性的90灰阶跳到正极性的100灰阶，此时灰阶数差是10。
这样就可以算出12根Data线的跳变灰阶数，对正极性的6个跳变灰阶和负极性的6个跳变灰阶进行大小以第一方式排序，比如按照从大到小的顺序排序：
正极性：G1>G3>G5>G7>G9>G11
负极性：G2>G6>G4>G10>G8>G12
可替代地，也可以按照从小到大的顺序排序。
最后，在步骤S303中，在每个子组中，根据确定的灰阶数差，在每个子组中的第二多条数据线之间选择性地进行电荷共享。
也就是说，与现有技术中将所有数据线的电压共同拉到公共电极的电压Vcom附近的方式不同，根据本申请第一实施例的驱动方法以数据线的上一行的灰阶数和下一行的灰阶数的差(即，跳变的显示信号电压差)为基础，根据预定策略选择两条数据线进行电荷共享，从而得到一个中和的电压，再 从该得到的中和电压分别抬升(或者降低)到所需要的电压。因为该中和的电荷更接近所需要的电压，所以更节省功耗。
因此，根据本申请第一实施例的驱动方法，能够根据上一行和下一行之间的数据差异，选择性地在两个数据线之间进行电荷共享，从而进一步节省功耗。
<第二实施例>
下面将结合图2和图4详细描述根据本申请第二实施例的驱动方法。在本实施例中，同样地以采用Z反转的液晶显示面板为例进行描述。
如图4所示，根据本申请第二实施例的驱动方法应用于例如图2所示的采用Z反转的液晶显示面板中，所述液晶显示面板包括第一多条数据线(例如，m条，m为正整数)，所述方法包括：
步骤S401：将所述第一多条数据线分组为多个子组，每个子组包括第二多条数据线；
步骤S402：针对每个子组的第二多条数据线，确定每条数据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差；
步骤S403：确定是否接收到极性反转信号；以及
步骤S404：在接收到极性反转信号时，在每个子组中的第二多条数据线的具有正极性的第三多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序；以及在每个子组中的第二多条数据线的具有负极性的第四多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序，第三多条数据线和第四多条数据线数量相同；
步骤S405：按照灰阶数差的顺序，在第三多条数据线中具有对应顺序的数据线和第四多条数据线中具有对应顺序的数据线之间进行电荷共享。
具体地，在步骤S401中，将m条数据线分为多个子组，每个子组包括第二多条数据线(例如，n条，n为正整数)。例如，在图2所示的实施例中，以n为12条为例进行说明。需要注意的是，n不限于12条，例如还可以为8条、16条、20条、20条等等，只要n为4的倍数。
然后，在步骤S402中，针对每个子组的第二多条数据线，确定每条数 据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差。
具体地，例如，对于图2所示的12条数据线，首先确定每条数据线的前一行的灰阶数，也就是说，确定每条数据线上的之前输出的显示信号电压。然后，确定每条数据线的下一行的灰阶数，也就是说，确定每条数据线上的即将输出的显示信号电压。然后，根据每条数据线上之前输出的显示信号电压和即将输出的显示信号电压，确定每条数据线上每次显示信号电压跳变的量，即，灰阶数差。
例如，可以按照上面的公式1确定每个子组中的12条数据线的灰阶数差G1-G12。
然后，在步骤S403中，确定是否接收到极性反转信号。如上面描述的，在液晶显示面板的多条数据线上交替地提供正极性和负极性的显示信号。每条数据线上的显示信号的极性通常以帧为单位进行切换。
如果接收到极性反转信号(POL信号)，则指示所有数据线上的信号的极性要反转。如果没有接收到极性反转信号(POL信号)，则指示所有数据线上的信号的极性不需要反转。例如，显示信号保持原来的极性，但是显示信号的大小会改变。
然后，在步骤S404中，在接收到极性反转信号时，在每个子组中的第二多条数据线的具有正极性的第三多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序；以及在每个子组中的第二多条数据线的具有负极性的第四多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序，第三多条数据线和第四多条数据线数量相同。
具体地，对于步骤S402中计算得到的12条数据线跳变灰阶数G1-G12，按照数据线的信号极性，对具有正极性的6个跳变灰阶和具有负极性的6个跳变灰阶进行大小排序，比如按照从大到小的顺序排序：
正极性：G1>G3>G5>G7>G9>G11
负极性：G2>G6>G4>G10>G8>G12
可替代地，也可以按照从小到大的顺序排序。
最后，在步骤S405中，按照灰阶数差的顺序，在第三多条数据线中具有对应顺序的数据线和第四多条数据线中具有对应顺序的数据线之间进行电荷共享。
需要注意的是，在接收到极性反转信号时，对于具有正极性的数据线来说，因为极性反转，所以都跳变为负极性。此时，将以跳变量的绝对值为基础进行排序。类似地，在接收到极性反转信号时，对于具有负极性的数据线来说，因为极性反转，所以都跳变为正极性。此时，将以跳变量的绝对值为基础进行排序。
具体地，将具有正极性跳变最大的G1的数据线与具有负极性跳变最大的G2的数据线电荷共享，将具有第二大的G3的数据线和具有第二大的G6的数据线电荷共享，具有第三大的G5的数据线和具有第三大的G4的数据线电荷共享，以此类推，完成每个子组中的数据线的两两配对。
也就是说，与现有技术中将所有数据线的电压共同拉到公共电极的电压Vcom附近的方式不同，根据本申请第二实施例的驱动方法以数据线的上一行的灰阶数和下一行的灰阶数的差(即，跳变的显示信号电压差)为基础，当接收到极性反转信号时，在具有不同极性的数据线之间，选择具有对应的灰阶数差的两条数据线进行电荷共享，从而得到一个中和的电压，再从该得到的中和电压分别抬升(或者降低)到所需要的电压。因为该中和的电荷更接近所需要的电压，所以更节省功耗。
因此，根据本申请第二实施例的驱动方法，能够根据上一行和下一行之间的数据差异，并且根据是否接收到极性反转信号，选择性地在两个数据线之间进行电荷共享，从而进一步节省功耗。
<第三实施例>
下面将结合图2和图5详细描述根据本申请第三实施例的驱动方法。在本实施例中，同样地以采用Z反转的液晶显示面板为例进行描述。
如图5所示，根据本申请第三实施例的驱动方法应用于例如图2所示的采用Z反转的液晶显示面板中，所述液晶显示面板包括第一多条数据线(例如，m条，m为正整数)，所述方法包括：
步骤S501：将所述第一多条数据线分组为多个子组，每个子组包括第二 多条数据线；
步骤S502：针对每个子组的第二多条数据线，确定每条数据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差；
步骤S503：确定是否接收到极性反转信号；以及
步骤S504：在没有接收到极性反转信号时，在每个子组中的第二多条数据线的具有正极性的第三多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序；以及在每个子组中的第二多条数据线的具有负极性的第四多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序，第三多条数据线和第四多条数据线数量相同；
步骤S505：按照灰阶数差的顺序，在每个子组中的第三多条数据线中具有相反的对应顺序的每两条数据线进行电荷共享，以及在每个子组中的第四多条数据线中具有相反的对应顺序的每两条数据线进行电荷共享。
具体地，在步骤S501中，将m条数据线分为多个子组，每个子组包括第二多条数据线(例如，n条，n为正整数)。例如，在图2所示的实施例中，以n为12条为例进行说明。需要注意的是，n不限于12条，例如还可以为8条、16条、20条、20条等等，只要n为4的倍数。
然后，在步骤S502中，针对每个子组的第二多条数据线，确定每条数据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差。
具体地，例如，对于图2所示的12条数据线，首先确定每条数据线的前一行的灰阶数，也就是说，确定每条数据线上的之前输出的显示信号电压。然后，确定每条数据线的下一行的灰阶数，也就是说，确定每条数据线上的即将输出的显示信号电压。然后，根据每条数据线上之前输出的显示信号电压和即将输出的显示信号电压，确定每条数据线上每次显示信号电压跳变的量，即，灰阶数差。
例如，可以按照上面的公式1确定每个子组中的12条数据线的灰阶数差G1-G12。
然后，在步骤S503中，确定是否接收到极性反转信号。如上面描述的，在液晶显示面板的多条数据线上交替地提供正极性和负极性的显示信号。每条数据线上的显示信号的极性通常以帧为单位进行切换。
如果接收到极性反转信号(POL信号)，则指示所有数据线上的信号的 极性要反转。如果没有接收到极性反转信号(POL信号)，则指示所有数据线上的信号的极性不需要反转。例如，显示信号保持原来的极性，但是显示信号的大小会改变。
然后，在步骤S504中，在没有接收到极性反转信号时，在每个子组中的第二多条数据线的具有正极性的第三多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序；以及在每个子组中的第二多条数据线的具有负极性的第四多条数据线中，按照每条数据线上的灰阶数差的大小以第一方式排序，第三多条数据线和第四多条数据线数量相同。
具体地，对于步骤S502中计算得到的12条数据线跳变灰阶数G1-G12，按照数据线的信号极性，对具有正极性的6个跳变灰阶和具有负极性的6个跳变灰阶进行大小排序，比如按照从大到小的顺序排序：
正极性：G1>G3>G5>G7>G9>G11
负极性：G2>G6>G4>G10>G8>G12
可替代地，也可以按照从小到大的顺序排序。
需要注意的是，在没有接收到极性反转信号时，对于具有正极性的数据线来说，因为极性没有反转，所以跳变量可能为正，也可能为负。此时，将以具有符号的跳变量的值为基础进行排序。即，跳变量为正的值大于跳变量为负的值。类似地，对于具有负极性的数据线来说，因为极性没有反转，所以跳变量可能为正，也可能为负。此时，将以具有符号跳变量的值为基础进行排序。即，跳变量为正的值大于跳变量为负的值。
最后，在步骤S505中，按照灰阶数差的顺序，在每个子组中的第三多条数据线中具有最大灰阶数差的数据线和具有最小灰阶数差的数据线之间进行电荷共享每两条数据线进行电荷共享，以及在每个子组中的第四多条数据线中具有最大灰阶数差的数据线和具有最小灰阶数差的数据线之间进行电荷共享每两条数据线进行电荷共享。
也就是说，与上面第二实施例的驱动方法不同的是，在本实施例中，当没有接收到极性反转信号时，不在不同极性的数据线之间进行电荷共享。相反，是在具有相同极性的数据线之间进行电荷共享，从而避免将源极电压拉到不期望的电压再分别抬升(或者降低)到所需要的电压的情况。
具体地，在具有正极性的数据线G1、G3、G5、G7、G9和G11中，将 具有最大的G1的数据线与具有最小的G11的数据线电荷共享，将具有第二大的G3的数据线和具有第二小的G9的数据线电荷共享，具有第三大的G5的数据线和具有第三小的G9的数据线电荷共享，从而完成每个子组中具有正极性的数据线的两两配对。
类似地，在具有负极性的数据线G2、G4、G6、G8、G10和G12中，将具有最大的G2的数据线与具有最小的G12的数据线电荷共享，将具有第二大的G4的数据线和具有第二小的G10的数据线电荷共享，具有第三大的G6的数据线和具有第三小的G8的数据线电荷共享，从而完成每个子组中具有负极性的数据线的两两配对。
也就是说，与现有技术中将所有数据线的电压共同拉到公共电极的电压Vcom附近的方式不同，根据本申请第三实施例的驱动方法以数据线的上一行的灰阶数和下一行的灰阶数的差(即，跳变的显示信号电压差)为基础，当没有接收到极性反转信号时，在具有相同极性的数据线之间，选择具有对应的灰阶数差的两条数据线进行电荷共享，从而得到一个中和的电压，再从该得到的中和电压分别抬升(或者降低)到所需要的电压。因为该中和的电荷更接近所需要的电压，所以更节省功耗。
因此，根据本申请第三实施例的驱动方法，能够根据上一行和下一行之间的数据差异，并且在没有接收到极性反转信号，也能够选择性地在两个数据线之间进行电荷共享，从而进一步节省功耗。
<第四实施例>
下面，将参考图2和图6描述根据本申请第四实施例的驱动方法。在本实施例中，同样地以采用Z反转的液晶显示面板为例进行描述。
如图6所示，根据本申请第四实施例的驱动方法应用于例如图2所示的采用Z反转的液晶显示面板中，所述液晶显示面板包括第一多条数据线(例如，m条，m为正整数)，所述方法包括：
步骤S601：将所述第一多条数据线分组为多个子组，每个子组包括第二多条数据线；
步骤S602：针对每个子组的第二多条数据线，确定每条数据线上的数据从前一行的灰阶到下一行的灰阶的灰阶数差；
步骤S603：确定是否接收到极性反转信号；以及
步骤S604：当接收到极性反转信号时，在所述第一多条数据线之间进行电荷共享。
步骤S601到步骤S603与第二实施例中的步骤S401到S403基本相同，在此省略其详细描述。
与第二实施例的驱动方法不同的是，当在步骤S603中接收到极性反转信号时，在第一多条数据线之间进行电荷共享。
因此，根据本申请第四实施例的驱动方法，能够根据上一行和下一行之间的数据差异，并且在接收到极性反转信号，在多条数据线之间进行电荷共享，从而进一步节省功耗。
