Description

显示面板的驱动方法及驱动装置 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及驱动装置。
 背景技术
目前常见的显示面板，由于液晶分子的偏转角或者由于OLED（Organic Light-Emitting Diode，有机发光二极管）器件的发光稳定性等原因，通常存在一定程度的色偏问题。
为了改善色偏问题，常见的一种显示面板的驱动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，并且在同一时刻，对每相邻的两个子像素分别施加极性相反的驱动电压。采用这种方式，虽然有时能改善色偏问题，但也会导致同一列同一颜色子像素的高电压的正负极性不匹配，即同一列中同一颜色正极性高电压的子像素数量与负极性高电压的子像素的数量不一致。这样，由于寄生电容的影响，当同一列同一颜色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，共电极电压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。

其中，所述显示面板具有呈矩阵分布的多个像素单元，每一所述像素单元包括多个子像素，例如，每一像素单元至少包括红色子像素、绿色子像素和蓝色子像素，可选地，每一像素单元还可包括白色子像素。
为进一步理解上述显示面板的驱动方法及驱动装置。下面结合附图进行说明。
请一并参阅图1至图2，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，所述驱动方法应设置为显示面板。如图1所示，所述驱动方法10包括以下步骤：
步骤S101，采用极性相反的驱动电压对每相邻的两行像素单元中位置相对应的子像素进行驱动。
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，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R（红色）子像素、G（绿色）子像素及B（蓝色）子像素这三种子像素。或者，每个像素单元分别包括R子像素、G子像素、B子像素和W（白色）子像素这四种子像素。
作为一种实施方式，对显示面板中的各子像素分别施加驱动电压，使得每相邻的两行像素单元中位置相对应的子像素的驱动电压极性相反。
其中，位置相对应指的是在一行像素单元中的相对位置或排列顺序一致，例如，每一像素单元包括按照一定顺序排列的第一子像素、第二子像素、第三子像素和第四子像素，则在相邻两行像素单元中，位于同一列的两个第一子像素为位置相对应的子像素；位于同一列的两个第二子像素为位置相对应的子像素；位于同一列的两个第三子像素为位置相对应的子像素；位于同一列的两个第四子像素为位置相对应的子像素。其中，上述一定顺序，可选的为从左到右的顺序、从右到左的顺序、从上到下的顺序或者从下到上的顺序。
步骤S102，采用极性相反的两种驱动电压对同一所述像素单元中的多个子像素进行驱动。
作为一种实施方式，若每个像素单元中包括3个子像素，则对其中一个子像素施加正极性的驱动电压，对另外两个子像素施加负极性的驱动电压；或者对其中一个子像素施加负极性的驱动电压，对另外两个子像素施加正极性的驱动电压。
作为一种实施方式，若每个像素单元中包括4个子像素，则对其中两个子像素施加正极性的驱动电压，对另外两个子像素施加负极性的驱动电压。可选地，对每相邻的两个子像素分别施加极性相反的驱动电压；或者，对中间的两个子像素施加第一极性的驱动电压，对边缘的两个子像素施加第二极性的驱动电压。例如，所述像素单元包括依序排列的第一子像素、第二子像素、第三子像素和第四子像素，步骤S102具体包括：采用第一极性的驱动电压对同一像素单元中的第一子像素和第四子像素进行驱动；采用第二极性的驱动电压对同一像素单元中的第二子像素和第三子像素进行驱动；其中，所述第一极性和所述第二极性互为相反极性。例如，当第一极性为正极性时，第二极性为负极性；当第一极性为负极性时，第二极性为正极性。这样，每个像素单元中同一颜色正极性的子像素数量和负极性的子像素数量相同，能够保证整个显示面板中每一列的高电压正极性子像素数量和高电压负极性子像素数量相同，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。
本申请实施例中，正极性指的是驱动电压大于显示面板预设的共电极电压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小于V com电压，即驱动电压与V com电压的压差小于零。
步骤S103，采用至少两种电压等级的驱动电压对同一像素单元中的多个子像素进行驱动。
其中，所述至少两种电压等级包括第一电压等级和第二电压等级，第一电压等级可大于或小于第二电压等级。例如，第一电压等级为高电压等级，第二电压等级为低电压等级；或者，第一电压等级为低电压等级，第二电压等级为高电压等级。
作为一种实施方式，分别采用第一电压等级和第二电压等级的驱动电压对同一像素单元中每相邻的两个子像素进行驱动，使得同一像素单元中每相邻的两个子像素的驱动电压等级高低不同。
作为一种实施方式，每个像素单元包括四个子像素，以相邻的2个子像素为一组，分别采用第一电压等级和第二电压等级的驱动电压对同一像素单元中每相邻的两组子像素进行驱动，使得同一像素单元中的两组子像素的驱动电压等级高低不同。
作为一种实施方式，分别采用第一电压等级和第二电压等级的驱动电压对显示面板中每相邻的两个子像素进行驱动，使得显示面板中每相邻的两个子像素的驱动电压等级高低不同。
作为一种实施方式，每个像素单元包括三个或四个子像素，以相邻的2个子像素为一组，分别采用第一电压等级和第二电压等级的驱动电压对显示面板中每相邻的两组子像素进行驱动，使得显示面板中的两组子像素的驱动电压等级高低不同。
具体地，所述显示面板的驱动方法还包括：将显示面板中的各子像素划分为高电压子像素和低电压子像素，采用高电压等级的驱动电压对高电压子像素进行驱动，采用低电压等级的驱动电压对低电压子像素进行驱动。其中，每个高电压子像素与一低电压子像素穿插设置，即，无论行向或列向，与高电压子像素相邻的均为低电压子像素，与低电压子像素相邻的均为高电压子像素；或者，每两个高电压子像素与两个低电压子像素穿插设置；或者，在第一方向上每两个高电压子像素与两个低电压子像素穿插设置，在第二方向上，每个高电压子像素与一个低电压子像素穿插设置，其中第二方向与第一方向相垂直，第一方向指的是像素单元中多个子像素排列的方向。
其中，高电压等级是指，对于所驱动的子像素，输入的驱动电压高于所述子像素的灰阶对应的预设电压值。类似地，低电压等级是指，对于所驱动的子像素，输入的驱动电压低于所述子像素的灰阶对应的预设电压值。例如，在正常驱动一个子像素时，若要显示0~255的灰阶，则对应需要输入V 0~V 255的驱动电压。本实施例中，以第一像素单元对应的第一驱动电压等级为高电压等级，第二像素单元对应的第二驱动电压等级为低电压等级为例，若任一个子像素的灰阶记为K，对应的预设电压值为V k（0≤k≤255，k为整数），则对第一像素单元中的每个子像素输入电压值高于V k的驱动电压，对第二像素单元中的每个子像素输入电压值低于V k的驱动电压。
由于高电压子像素与低电压子像素在显示面板中穿插设置，这样，使得每相邻两个子像素的驱动电压的电压等级高低不同，或者使得每隔若干个子像素驱动电压的电压等级发生变化，使得像素单元在侧视角下的灰阶亮度曲线接近于正视角下的灰阶亮度曲线，从而改善侧视角下的色偏问题。
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”。
实际应用中，步骤S101、步骤S102和步骤S103可同时进行。即，对显示面板中的各子像素施加驱动电压，使得每相邻的两行像素单元中位置相对应的子像素的驱动电压极性相反，并且同一所述像素单元中的多个子像素的驱动电压极性不完全相同，并且同一像素单元中多个子像素的驱动电压等级不完全相同。这样，不仅使得每相邻两个像素单元的驱动电压的电压等级高低不同，能够改善侧视角下的色偏问题，而且使得在显示面板的每一列（row）同一颜色像素中，驱动电压为正极性高电压等级的子像素的数量与驱动电压为负极性高电压等级的子像素的数量相同，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，在对显示面板的子像素施加驱动电压之前，上述显示面板的驱动方法还包括：获取外部输入的图像数据，根据所述图像数据确定显示面板的每个子像素的灰阶数据；在步骤S104，根据每个子像素的灰阶数据和每个子像素对应的电压等级，生成每个子像素对应的驱动电压值，采用对应的驱动电压值分别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。
请一并参阅图2及图3，其中P表示像素单元，（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；反之亦可。以每一像素单元分别包括红色子像素、绿色子像素、蓝色子像素和白色子像素为例，R代表红色子像素素，G代表绿色子像素，B代表蓝色子像素，W代表白色子像素。H表示第一驱动电压等级，L表示第二驱动电压等级。
根据步骤S101，采用极性相反的驱动电压对每相邻的两行像素单元中位置相对应的子像素进行驱动。如图3所示，每一像素单元包括依序排列的第一子像素、第二子像素、第三子像素和第四子像素，分别为R子像素、G子像素、B子像素和W子像素。以相邻的第j行像素单元和第j+1行像素单元为例，对这两行像素单元中位于第i列的两个第一子像素R（i，j）和R（i，j+1）施加极性相反的驱动电压；对这两行像素单元中位于第i列的两个第二子像素G（i，j）和G（i，j+1）施加极性相反的驱动电压；对这两行像素单元中位于第i+1列的两个第一子像素R（i+1，j）和R（i+1，j+1）施加极性相反的驱动电压；以此类推，使每相邻两行像素单元中位置相对应的两个子像素的驱动电压极性相反。
根据步骤S102，采用极性相反的两种驱动电压对同一所述像素单元中的多个子像素进行驱动。如图3所示，以第j行第i列的像素单元P1（i，j）为例，在某一帧画面的显示时间内，对其中的第一子像素R（i，j）和第四子像素W1（i，j）施加正极性的驱动电压，对其中的第二子像素G（i，j）和第三子像素B（i，j）施加负极性的驱动电压，使同一像素单元的多个子像素的驱动电压不完全相同。
根据步骤S103，采用至少两种电压等级的驱动电压对同一像素单元中的多个子像素进行驱动。例如，当每个像素单元包括四个子像素时，步骤S103包括：采用第一电压等级的驱动电压对所述像素单元中的两个子像素进行驱动；采用第二电压等级的驱动电压对所述像素单元中的另两个子像素进行驱动。
其中，以每相邻两个子像素的驱动电压等级不同为例，如图3所示，与第j行第i列的R子像素相邻的子像素包括第j行第i+1列的R子像素和第j行第i列的G子像素，则对第j行第i列的R子像素施加H等级的驱动电压，对第j行第i+1列的R子像素和第j行第i列的G子像素施加L等级的驱动电压，使得每相邻两个子像素的驱动电压等级不同。
采用上述驱动方法，能够使得液晶面板的每一列（row）像素中同一颜色子像素，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R子像素和代表负极性高电压等级（H-）的R子像素各有2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，上述驱动方法还包括：采用极性相同的驱动电压对同一行的子像素进行驱动。如图3所示，第j行的R子像素均被施加正极性的驱动电压，第j行的G子像素均被施加负极性的驱动电压，第j行的B子像素均被施加负极性的驱动电压，第j行的W子像素均被施加正极性的驱动电压。这样，由于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，从而可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。
其中，若上述显示面板为液晶面板，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，缩短液晶面板的寿命，因此为了保护液晶材料及电极，延长显示面板的寿命，对显示面板中的每个子像素进行交流驱动。在一个实施例中，上述驱动方法还包括：在每相邻的两帧显示时间内，采用极性相反的驱动电压对同一所述子像素进行驱动；即，对于同一个子像素，在每相邻的两帧显示时间内，分别施加不同极性的驱动电压以达到交流驱动的效果。更明确地说，相邻的两帧显示时间包括第一显示时间和第二显示时间，于所述第一显示时间内，施加第三极性的驱动电压于同一所述子像素进行驱动，于所述第二显示时间内，施加第四极性的驱动电压于同一所述子像素进行驱动，且所述第三极性的驱动电压和所述第四极性的驱动电压数值相同但极性相异。例如，在第m帧画面的显示时间内，对显示面板中的一些子像素施加如图3所示的驱动电压，而在第m+1帧画面的显示时间内，对上述子像素施加如图4所示的驱动电压，看出同一像素于第m帧画面的显示时间和第m+1帧画面的显示时间的极性相异。可见，在每相邻的两帧显示时间内，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。这样，能够实现对每个子像素进行交流驱动，保护液晶材料及电极，延长液晶显示面板的寿命。
请参阅图5，其为本申请另一个实施例的显示面板的驱动方法的流程示意图，所述驱动方法50包括如下步骤：
S501，将所述显示面板中的子像素划分为第一电压等级子像素和第二电压等级子像素。
其中，所述第一电压等级子像素和所述第二电压等级子像素在所述显示面板中穿插设置。
S502，采用极性相反的驱动电压对每相邻的两行像素单元中位置相对应的子像素进行驱动。
S503，采用极性相反的两种驱动电压对同一所述像素单元中的多个子像素进行驱动。
其中，步骤S502和步骤S503的具体实现方式可参考图1至4所示实施例中步骤S101和步骤S102的实施方式，此处不再赘述。
S504，采用第一电压等级的驱动电压对所述第一电压等级子像素进行驱动，以及，采用第二电压等级的驱动电压对所述第二电压等级子像素进行驱动。
作为一种实施方式，步骤S502、步骤S503和步骤S504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，使得每相邻的两行像素单元中位置相对应的子像素的驱动电压极性相反，并且同一所述像素单元中的多个子像素被施加极性相反的两种驱动电压，并且第一电压等级子像素的驱动电压等级为第一电压等级，第二第一电压等级子像素的驱动电压等级为第二电压等级。
作为一种实施方式，第一电压等级和第二电压等级分别为高电压等级和低电压等级。则具体地，将显示面板中的各子像素划分为高电压子像素和低电压子像素，采用高电压等级的驱动电压对高电压子像素进行驱动，采用低电压等级的驱动电压对低电压子像素进行驱动。其中，每个高电压子像素与一低电压子像素穿插设置，即，无论行向或列向，与高电压子像素相邻的均为低电压子像素，与低电压子像素相邻的均为高电压子像素；或者，每两个高电压子像素与两个低电压子像素穿插设置；或者，在第一方向上每两个高电压子像素与两个低电压子像素穿插设置，在第二方向上，每个高电压子像素与一个低电压子像素穿插设置，其中第二方向与第一方向相垂直，第一方向指的是像素单元中多个子像素排列的方向。
由于高电压子像素与低电压子像素在显示面板中穿插设置，这样，使得每相邻两个子像素的驱动电压的电压等级高低不同，或者使得每隔若干个子像素驱动电压的电压等级发生变化，使得像素单元在侧视角下的灰阶亮度曲线接近于正视角下的灰阶亮度曲线，从而改善侧视角下的色偏问题，亦即，不论从正视角或侧视角观看由高电压子像素与低电压子像素显示的画面，皆能观看到相同色阶的画面。
作为一种实施方式，在驱动显示面板时，对于每个子像素，确定其驱动电压的电压等级和极性后，根据各子像素的图像数据、对应的驱动电压极性和电压等级，得到各子像素的驱动电压，通过数据线将所述驱动电压施加至各子像素。
本申请实施例还提供了一种显示面板的驱动装置60。其中所述显示面板具有呈矩阵分布的多个像素单元，每个像素单元包括多个子像素，例如每个像素单元包括R子像素、G子像素和B子像素，又如每个像素单元包括R子像素、G子像素、B子像素和W子像素。
如图6所示，所述驱动装置60包括第一驱动模块610、第二驱动模块620及第三驱动模块630，其中第一驱动模块610设置为采用极性相反的驱动电压对每相邻的两行像素单元中位置相对应的子像素进行驱动；第二驱动模块620设置为采用极性相反的两种驱动电压对同一所述像素单元中的多个子像素进行驱动；第三驱动模块630设置为采用至少两种电压等级的驱动电压对同一像素单元中的多个子像素进行驱动。这样，不仅使得每相邻两个像素单元的驱动电压的电压等级高低不同，能够改善侧视角下的色偏问题，而且使得在显示面板的每一列（row）像素中同一颜色子像素，驱动电压为正极性高电压等级的子像素的数量与驱动电压为负极性高电压等级的子像素的数量相同，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，所述像素单元包括依序排列的第一子像素、第二子像素、第三子像素和第四子像素；如图7所示，所述第二驱动模块620包括第一驱动单元621和第二驱动单元622，其中第一驱动单元621设置为采用第一极性的驱动电压对同一像素单元中的第一子像素和第四子像素进行驱动；第二驱动单元622设置为采用第二极性的驱动电压对同一像素单元中的第二子像素和第三子像素进行驱动；其中，所述第一极性和所述第二极性互为相反极性。这样，每个像素单元中正极性的子像素数量和负极性的子像素数量相同，能够保证整个显示面板中每一列的同一颜色子像素高电压正极性子像素数量和高电压负极性子像素数量相同，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，所述第二驱动模块620包括第三驱动单元，设置为采用极性相反的驱动电压对同一所述像素单元中每相邻的两个子像素进行驱动。更明确地说，极性相反的驱动电压包括第三极性的驱动电压和第四极性的驱动电压，且第三极性的驱动电压和第四极性的驱动电压极性相异。第三驱动单元于第一驱动时间内施加第三极性的驱动电压于同一像素单元中相邻的两个子像素进行驱动，第三驱动单元于第二驱动时间内施加第四极性的驱动电压于同一像素单元中相邻的两个子像素进行驱动。
这样，当像素单元包括偶数个子像素时，例如当像素单元包括R子像素、G子像素、B子像素和W子像素，每个像素单元中正极性的子像素数量和负极性的子像素数量相同，能够保证整个显示面板中每一列的同一颜色子像素高电压正极性子像素数量和高电压负极性子像素数量相同，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，如图8所示，所述像素单元包括四个子像素；所述第三驱动模块630包括：第四驱动单元631，设置为采用第一电压等级的驱动电压对所述像素单元中的两个子像素进行驱动；第五驱动单元632，设置为采用第二电压等级的驱动电压对所述像素单元中的另两个子像素进行驱动。
在其中一个实施例中，所述驱动装置60还包括第四驱动模块，设置为采用极性相同的驱动电压对同一行的子像素进行驱动。这样，由于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范围内，从而可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，所述驱动装置60还包括第五驱动模块，设置为在每相邻的两帧显示时间内，采用极性相反的驱动电压对同一所述子像素驱动。这样能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。
请参阅图9，其为本申请另一个实施例的显示面板的驱动装置的结构示意图，所述驱动装置90包括分组模块910、第一驱动模块920、第二驱动模块930及第三驱动模块940。

其中，第一驱动模块920和第二驱动模块930的具体实施方式可参考图6至8所示实施例中第一驱动模块610和第二驱动模块620的实现方式，此处不再赘述。
本实施例中，第一电压等级子像素和第二电压等级子像素在所述显示面板中穿插设置。
例如，第一电压等级和第二电压等级分别为高电压等级和低电压等级。则具体将显示面板中的各子像素划分为高电压子像素和低电压子像素，采用高电压等级的驱动电压对高电压子像素进行驱动，采用低电压等级的驱动电压对低电压子像素进行驱动。其中，每个高电压子像素与一低电压子像素穿插设置，即无论行向或列向，与高电压子像素相邻的均为低电压子像素，与低电压子像素相邻的均为高电压子像素；或者，每两个高电压子像素与两个低电压子像素穿插设置；或者，在第一方向上每两个高电压子像素与两个低电压子像素穿插设置，在第二方向上，每个高电压子像素与一个低电压子像素穿插设置，其中第二方向与第一方向相垂直，第一方向指的是像素单元中多个子像素排列的方向。
由于高电压子像素与低电压子像素在显示面板中穿插设置，这样，使得每相邻两个子像素的驱动电压的电压等级高低不同，或者使得每隔若干个子像素驱动电压的电压等级发生变化，使得像素单元在侧视角下的灰阶亮度曲线接近于正视角下的灰阶亮度曲线，从而改善侧视角下的色偏问题。
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”，可以是本领域普通技术人员所理解的“列”，本申请实施例中的“列”，也可以是本领域技术普通人员所理解的“行”。
