Description

显示面板的驱动方法、驱动装置及显示装置 技术领域
本申请涉及显示技术领域，特别是涉及一种显示面板的驱动方法、驱动装置及显示装置。
背景技术
范例性的垂直配向(Vertical Alignment，VA)液晶显示装置，在显示画面时，由于液晶分子维持一定的偏转角，使得在不同视角下光的透过率不同，造成使用者在不同视角观看画面时会感受到画面的颜色有所差异的色偏现象。
为了改善色偏问题，目前一般的做法是将每个像素单元中RGB子像素的像素电极划分为两个独立的像素电极，对两个像素电极分别施加不同的驱动电压来改善色偏的问题。这种方法，由于像素电极数量的增加，需要重新设计更多的金属走线或TFT(Thin Film Transistor，薄膜晶体管)元件来驱动显示面板，而金属走线和TFT元件不透光，因此这种方法会牺牲可透光开口区、影响面板的透过率、提升背光成本。
为了避免增加金属走线或TFT元件，另一种方法是对每相邻的两个像素单元分别施加高、低两种不同的驱动电压信号，具体的，在同一时刻，对每相邻的两个子像素被施加不同极性的驱动电压。采用这种方式，会导致同一列子像素的高电压的正负极性不匹配，即，同一列的子像素中，被施加正极性高电压的子像素的数量和被施加负极性高电压的子像素的数量不相同。这样，由于寄生电容的影响，当同一列正极性高电压的子像素数量多于负极性高电压的子像素数量时，公共电压V com的等效电压相较于原V com有所提高，导致正极性高电压的子像素实际充电电荷减少、亮度降低，相反地使得负极性高电压子像素实际充电电荷增加、亮度增加，进而影响显示颜色及画质，产生画质输出异常的问题。
发明内容
基于此，有必要提供一种显示面板的驱动方法、驱动装置及显示装置，能够使得V com电压免受干扰，保证图像信号的正确性，提升画面显示质量。

为了进一步理解上述显示面板的驱动方法、驱动装置及显示装置。下面结合附图进行说明。
请一并参阅图1至图3，其中图1为本申请一实施例的显示面板的驱动方法的流程示意图，该驱动方法应用于显示面板。如图1所示，该显示面板的驱动方法10包括以下步骤：
S101，将显示面板中的多个子像素划分为若干子像素组，使每一所述子像素组包括两行相邻的子像素。
S102，利用极性相反的驱动电压对每相邻的两个所述子像素组中的子像素进行驱动。
S103，利用电压等级不同的驱动电压对第一像素单元中的子像素和第二像素单元中的子像素进行驱动。
实际应用中，步骤S102和步骤S103可同时进行。例如，在同一帧画面的显示时间内，对显示面板中的各子像素分别施加驱动电压，使得每相邻的两个所述子像素组中的子像素的驱动电压极性相反，并且所述第一像素单元中的子像素和所述第二像素单元中的子像素的驱动电压的等级不同。
其中，如图2所示，显示面板20具有呈矩阵分布的多个像素单元，所述多个像素单元包括若干第一像素单元P1及若干第二像素单元P2，所述第一像素单元与所述第二像素单元相邻设置，或者说第一像素单元与第二像素单元交替排列。具体的，每一所述像素单元包括多个子像素，例如每个像素单元包括颜色不同的多个子像素，又如每个像素单元分别包括红色子像素R、绿色子像素G及蓝色子像素B这三种子像素。其中(i，j)表示第i列第j行，(i，j+1)表示第i列第j+1行，(i+1，j)表示第i+1列第j行，以此类推。
例如，如图3所示，以4列像素单元中的12行子像素为例，将这12行子像素划分为第n至第n+5共6个子像素组，使得每个子像素组包括两行相邻的子像素。其中，R1、G1和B1分别表示第一像素单元中的红色子像素、绿色子像素及蓝色子像素。R2、G2和B2分别表示第二像素单元中的红色子像素、绿色子像素及蓝色子像素。H表示第一电压等级，L表示第二电压等级，+表示正极性，-表示负极性。(i，j)表示第i列第j行，(i，j+1)表示第i列第j+1行，(i+1，j)表示第i+1列第j行，以此类推。
其中，本申请实施例的行和列表示相互垂直的两种排列方向，例如，行表示纵向，列表示横向；又如，行表示横向，列表示纵向。即，本申请实施例中的“行”，可以是本领域技术人员所理解的“列”，本申请实施例中的“列”，也可以是本领域技术人员所理解的“行”。
本实施例中，同一子像素组中位于同一列的两个子像素可以是同一个像素单元中的子像素，也可以是不同像素单元中的子像素。例如，第n子像素组中位于同一列的R子像素和G子像素属于同一个像素单元，而第n+1子像素组中位于同一列的B子像素和R子像素则分属于相邻的两个像素单元。
具体地，针对任意相邻的两个子像素组，对其中一组的子像素施加正极性的驱动电压，对另一组的子像素施加负极性的驱动电压，而每个子像素的驱动电压等级则取决于其所属的像素单元。例如，分别预先设置第一像素单元和第二像素单元各自对应的驱动电压等级，又如，预先设置第一像素单元对应的第一电压等级及第二像素单元对应的第二电压等级，步骤S202包括：利用极性相反的第一驱动电压对所述第一像素单元中位于不同子像素组的子像素进行驱 动；并且，利用极性相反的第二驱动电压对所述第二像素单元中位于不同子像素组的子像素进行驱动；其中所述第一驱动电压的电压等级为预设的第一电压等级，所述第二驱动电压的电压等级为预设的第二电压等级。又如，利用极性相反的第一驱动电压对所述第一像素单元中位于不同子像素组的子像素进行驱动，具体为：分别利用正极性的第一驱动电压和负极性的第一驱动电压对所述第一像素单元中位于不同子像素组的子像素进行驱动。利用极性相反的第二驱动电压对所述第二像素单元中位于不同子像素组的子像素进行驱动，具体为：分别利用正极性的第二驱动电压和负极性的第二驱动电压对所述第二像素单元中位于不同子像素组的子像素进行驱动。
其中，第一电压等级和第二电压等级中，一个为高电压等级，另一个为低电压等级。例如，第一电压等级高于第二电压等级，或者第一电压等级低于第二电压等级。本实施例中，正极性指的是驱动电压的大小大于显示面板预设的公共电压V com，即驱动电压与V com电压的压差大于零；负极性指的是驱动电压的大小小于V com电压，即驱动电压与V com电压的压差小于零。
例如，如图3所示，对第n组、第n+2组及第n+4组中的每个子像素施加正极性的驱动电压，对第n+1组、第n+3组及第n+5组中的每个子像素施加负极性的驱动电压，其中属于第一像素单元的子像素的驱动电压等级为高(H)，属于第二像素单元的子像素的驱动电压等级为低(L)。这样，每一列中，被施加正极性高电压等级(H+)驱动电压的子像素的数量和被施加负极性高电压等级(H-)驱动电压的子像素的数量相等，例如图3中的每一列，代表正极性高电压等级(H+)的子像素和代表负极性高电压等级(H-)的子像素各有3个。高电压等级正负极性的子像素数量相同能够使得V com电压免受寄生电容的影响，从而确保图像信号的正确性，避免发生色偏或画质异常的现象。
在一个实施例中，考虑到若同一行(column)相邻的子像素驱动电压极性不同，会使得同一条数据线输出的电压信号频繁在高低电压之间跳跃，不仅可能造成数据驱动芯片发热，还可能由于显示面板负载的影响，使得电压信号失真导致像素充电不足。为解决这一问题，本实施例中，所述驱动方法还包括：在每一帧画面的显示时间内，利用极性相同的驱动电压对同一子像素组内的各 子像素进行驱动。即，在同一帧画面的显示时间内，对同一子像素组内的各子像素施加极性相同的驱动电压。这样，使得同一子像素组内每相邻的两列子像素的驱动电压的极性相同并且驱动电压等级不同。在任意一帧画面的显示时间内，属于相同子像素组的多个子像素受到极性相同的驱动电压，其中属于相同子像素组并且属于相邻两个像素单元的子像素受到极性相同并且电压等级不同的驱动电压，而属于相同子像素组并且属于同一像素单元的子像素则受到极性相同及电压等级相同的驱动电压。由于同一行的子像素的驱动电压极性相同，因此使同一数据线输出的多个电压信号之差维持在较小的范围内，能避免数据驱动芯片发热或电压信号失真，提升各子像素的显示质量。
在一个实施例中，当显示面板为液晶显示面板时，考虑到直流电场驱动液晶像素容易导致液晶材料发生化学反应并加速电极老化，进而缩短显示面板的寿命，因此为了保护液晶材料及电极，延长显示面板的寿命，本实施例对显示面板中的每个子像素进行交流驱动。具体地，对于同一个子像素，在每相邻的两帧画面的显示时间内，分别施加不同极性的驱动电压以达到交流驱动的效果。例如，所述驱动方法还包括：在每相邻的两帧显示时间内，利用极性相反的驱动电压对同一所述子像素进行驱动，或者说，对每一所述子像素，在每一帧画面的显示时间内，施加与上一帧画面的显示时间极性相反的驱动电压。例如，在第m帧画面的显示时间内，显示面板中一些子像素采用如图3所示的驱动电压，而在第m+1帧画面的显示时间内，上述一些子像素采用如图4所示的驱动电压。可见，在每相邻的两帧画面的显示时间内，同一子像素的驱动电压极性发生变化，并且驱动电压等级保持不变。
作为一种实施方式，在驱动显示面板时，对于每个子像素，根据其所属的子像素组确定驱动电压极性，根据其所属的像素单元确定驱动电压等级，进而通过预设的数据处理电路，根据各子像素的图像数据、对应的驱动电压极性和等级，得到各子像素的驱动电压，通过数据线将该驱动电压施加至各个子像素。
采用上述显示面板的驱动方法，驱动显示面板分别对如图5a、图5b、图5c、图5d、图5e、图5f、图5g及图5h所示这几种特定的测试画面进行显示，图中填充有黑色斜线的子像素表示该子像素对应的数据信号为暗态信号。经过实验， 发现图5a和图5b的闪烁(Flicker)画面至图5h的画面显示无色偏问题，图5c的画面能够避免水平方向的串扰，图5d均无色偏问题，其中图5d表示每隔一个像素单元交替亮/暗显示的画面，图5e表示每隔两个像素单元交替亮/暗显示的画面，图5f表示每隔一个子像素交替亮/暗显示的画面，图5g表示每隔一列子像素交替亮/暗显示的画面，图5h表示每隔一列像素单元交替亮/暗显示的画面。由此可见，本申请实施例的显示面板的驱动方法具有良好的色偏改善效果。
本申请实施例还提供了一种显示面板的驱动装置。该显示面板的驱动装置应用于显示面板，例如该显示面板的驱动装置用于驱动显示面板。显示面板具有呈矩阵分布的多个像素单元，其中，所述多个像素单元包括若干第一像素单元及若干第二像素单元，所述第一像素单元与所述第二像素单元相邻设置，并且每一所述像素单元包括多个子像素。
如图6所示，该显示面板的驱动装置60包括分组模块610、第一驱动模块620及第二驱动模块630。其中分组模块610用于将显示面板中的多个子像素划分为若干子像素组，使每一所述子像素组包括两行相邻的子像素；第一驱动模块620用于利用极性相反的驱动电压对每相邻的两个所述子像素组中的子像素进行驱动；第二驱动模块630用于利用电压等级不同的驱动电压对第一像素单元中的子像素和第二像素单元中的子像素进行驱动。这样，每一列中，被施加正极性高电压等级(H+)驱动电压的子像素的数量和被施加负极性高电压等级(H-)驱动电压的子像素的数量相等，使得V com电压免受寄生电容的影响，从而确保图像信号的正确性，避免发生色偏或画质异常的现象。
在其中一个实施例中，所述驱动装置还包括：第三驱动模块，用于在每相邻的两帧画面的显示时间内，利用极性相反的驱动电压对同一所述子像素进行驱动。这样，能够对各子像素进行交流驱动，从而保护液晶材料及电极，延长显示面板的寿命。
在其中一个实施例中，所述驱动装置还包括：第四驱动模块，用于在每一帧画面的显示时间内，利用极性相同的驱动电压对同一子像素组内的各子像素进行驱动。这样，能保证同一行的子像素的驱动电压极性相同，使同一数据线输出的多个电压信号之差维持在较小的范围内，以避免数据驱动芯片发热或电 压信号失真，提升各子像素的显示质量。
在其中一个实施例中，所述第二驱动模块630包括第一驱动单元及第二驱动单元，第一驱动单元用于利用极性相反的第一驱动电压对所述第一像素单元中位于不同子像素组的子像素进行驱动；第二驱动单元用于利用极性相反的第二驱动电压对所述第二像素单元中位于不同子像素组的子像素进行驱动；其中所述第一驱动电压的电压等级为预设的第一电压等级，所述第二驱动电压的电压等级为预设的第二电压等级。这样，能够保证每相邻的两个像素单元的驱动电压等级高低不同，且每相邻两个子像素组中的子像素的驱动电压极性相反。
