Description

显示面板的驱动方法、驱动装置以及显示设备
本申请要求于2019年1月30日提交中国专利局、申请号为201910094557.9、发明名称为“显示面板的驱动方法、驱动装置以及显示设备”的中国专利申请的优先权，其全部内容通过引用结合在申请中。
技术领域
本申请涉及液晶面板显示领域，尤其涉及一种显示面板的驱动方法、驱动装置以及显示设备。
背景技术
大尺寸液晶显示面板大多采用负型垂直配向(Vertical Alignment，VA)式或者共平面切换(In Panel Switching，IPS)式。VA型液晶技术相较于IPS液晶技术存在较高的生产效率及低制造成本的优势，但相较于IPS液晶技术，则存在较明显的光学性质缺陷，例如在大视角图像呈现时，VA型液晶显示面板会存在色偏。
在进行图像显示时，像素的亮度在理想情况下应该是随着电压的变化呈现线性的变化，这样像素的驱动电压就能够准确表示像素的灰阶，并通过亮度体现出来。而采用VA型液晶技术时，以较小的视角观看显示面时(例如正视)，像素的亮度可以符合理想情况，即随电压呈现线性变化；但当以较大的视角观看显示面时(例如与显示面呈160度以上)，由于VA型液晶技术原理所限，像素的亮度随着电压呈现出快速饱和，然后缓慢变化的情况。这样一来，大视角下，驱动电压原本应该呈现的灰阶，出现了严重的偏离，即出现色偏。
传统用于改善色偏的方式是将每一个子像素都再细分为一个主像素和次像素，然后用相对高的驱动电压驱动主像素，用相对低的驱动电压驱动次像素，主像素和次像素一起显示一个子像素。并且所述相对高的驱动电压和相对低的驱动电压在驱动主像素和次像素时，能够维持正视视角下的亮度与对应灰阶的关系不变。一般地，灰阶的前半段，主像素用相对高的驱动电压驱动显示、次像素不显示，整个子像素的亮度就是主像素亮度的一半；在灰阶的后半段，主像素用相对高的驱动电压驱动显示、次像素用相对低的驱动电压驱动显示，整个子像素的亮度就是主像素的亮度加上次像素的亮度的和的一半。这样合成后，大视角下的亮度曲线更接近理想曲线，因此大视角下的色偏情况有所改善。
但上述方法存在的问题是，需要增加一倍的金属走线和驱动器件来驱动次像素，使可透光开口区牺牲，影响面板透光率，同时成本也更高。

参考图1，图1为本申请一种显示面板的驱动装置的一实施例示意图；
如图1所示， 本实施例中所述显示面板200包括显示阵列，所述显示阵列包括呈阵列排布的像素单元001，所述像素单元001包括行方向上依次排列的三列子像素（第一列子像素为R子像素，第二列子像素为G子像素，第三列子像素为B子像素），所述显示阵列中相邻像素单元互为高低电压强度穿插排列；并且所述显示阵列中行方向上的相邻的子像素的极性不同，且所述显示阵列中列方向上的相邻的子像素的极性不同。
可理解的是，如图1中显示面板200的显示阵列所示，在一个像素单元001中包括行方向上依次排列的R子像素（红）、G子像素（绿）、B子像素（蓝）。
所述显示阵列中相邻的子像素的电压强度不同，即子像素的电压强度可分为低电压强度（如图1中带有L标识的子像素）、以及高电压强度（如图1中带有H标识的子像素）。
可理解的是，高电压单位子像素的显示灰阶比较亮，而低电压单位子像素的显示灰阶比较暗，如图四所示，相邻R子像素、G子像素、B子像素为高低电压穿插驱动排列方式。
本实施例中，高电压单位子像素为正极性，即配合显示面板驱动高电压子像素采用正极性驱动；而低电压单位子像素为负极性，即配合显示面板驱动低电压子像素采用负极性驱动。
所述驱动装置100包括处理器和存储器，所述存储器存储可执行指令，所述处理器执行所述可执行指令，所述可执行指令包括:
第一驱动模块110，设置于以显示面板的两帧运行画面为一驱动周期，在第一帧内对单个像素单元中第一列子像素和第三列子像素的共电极采用第一预设电压进行点反转驱动；并对所述单个像素单元中第二列子像素的共电极采用第二预设电压进行点反转驱动；
需要说明的是，本实施例中的共电驱动电压相对于显示面板的原共电极电压采取正负极性驱动方式进行工作。为方便描述，将显示面板的原共电极电压作为参考电压记作Vcom，将所述第一预设电压记为Vcom1，所述第二预设电压记为Vcom2。
本实施例的显示面板的驱动装置还包括栅极驱动模块，设置于所述显示阵列的一侧，在所述显示阵列的行方向上向各像素单元传送扫描信号；源极驱动模块，设置于所述显示阵列的一端，在所述显示阵列的列方向上向各像素单元传送源极驱动信号；
需要说明的是，本实施例的一条扫描信号在行方向上扫描一行子像素。
具体地，在本实施例中，以显示面板的两帧运行画面为一驱动周期，在第一帧内接收到所述栅极驱动模块传送的扫描信号时，对扫描到的单个像素单元中第一列子像素和第三列子像素的共电极采用第一预设电压Vcom1进行点反转驱动，此时Vcom1相对于参考电压Vcom较小，所以单个像素单元中第一列子像素和第三列子像素的共电极表现为负极性，即Vcom1表征为负极性驱动电压；例如扫描到的是第一行第二列像素单元，那么就对扫描到的该像素单元中第一列子像素VRd_1和第三列子像素VBd_1的共电极采用第一预设电压Vcom1进行点反转驱动;
同时，第一行第二列像素单元在接收到所述栅极驱动模块传送的上述扫描信号时，对其第二列子像素VGd_1的共电极采用第二预设电压Vcom2进行点反转驱动；此时Vcom2相对于参考电压Vcom较大，所以单个像素单元中第二列子像素的共电极表现为正极性，即Vcom2表征为正极性驱动电压，对单个像素单元中第二列子像素的共电极采用反转后的的Vcom2进行点反转驱动。
第二驱动模块120，设置于在第二帧内将所述第一预设电压的极性进行周期性反转，对所述单个像素单元中第一列子像素和第三列子像素的共电极采用反转后的的第一预设电压进行点反转驱动；并将所述第二预设电压的极性进行周期性反转，对所述单个像素单元中第二列子像素的共电极采用反转后的的第二预设电压进行点反转驱动。
具体地，在本实施例中，在第二帧内将所述第一预设电压Vcom1的极性进行周期性反转，对单个像素单元中第一列子像素和第三列子像素的共电极采用反转后的的Vcom1电压进行点反转驱动，此时Vcom1相对于参考电压Vcom较大，所以单个像素单元中第一列子像素和第三列子像素的共电极表现为正极性，即Vcom1表征为正极性驱动电压；并将所述第二预设电压Vcom2的极性进行周期性反转，此时Vcom2相对于参考电压Vcom较小，所以单个像素单元中第二列子像素的共电极表现为负极性，即Vcom2表征为负极性驱动电压，对单个像素单元中第二列子像素的共电极采用反转后的的Vcom2进行点反转驱动。当显示面板的运行一帧图像后，对于某一列像素单元来说，例如第二列像素单元，参考图2，图2中低电压子像素VGd_1、VGd_3、VGd_5由正极性变为负极性驱动，高电压子画素VGd_2、VGd_4、VGd_6由负极性变为正极性驱动，依次类推每列像素单元在显示面板的运行一帧图像后均是如此。
本实施例的显示面板中的显示阵列中相邻像素单元互为高低电压强度穿插排列，所述显示阵列中相邻的子像素的极性不同，同一行子像素的共电极设置两个不同的预设电压，驱动装置在一个驱动周期内根据两个不同的预设电压驱动对显示阵列中的子像素进行点反转驱动，能够在减少显示面板视角色偏的现象出现的几率，显示面板以这种驱动周期运行，能够使得显示面板的视角色偏问题得到改良。
进一步地，在实现在如上所述的子像素点反转的驱动方式过程中，在列方向上，如果采用常规的一列子像素仅由一列源极驱动信号控制，会出现在同一列源极驱动信号的极性频繁驱动；
本实施例中，源极驱动模块对应设置有与所述源极驱动模块连接的源极数据线，所述源极数据线连接两列相邻的子像素；所述源极数据线在列方向上控制单个像素单元中相邻两列子像素中极性相同且电压强度不同的子像素。可以减少驱动IC的工作，降低了驱动IC的功耗及驱动IC的温度提升风险。如图2所示，以第二列像素单元为例，第二列像素单元的子像素VGd_1、子像素VRd_2、子像素VGd_3的子像素的极性为正极性，子像素VGd_1与子像素VRd_2的电压强度不同，且子像素VRd_2与子像素的电压强度不同也不同VGd_3，它们共受一列源极驱动信号Vd1驱动驱动；
VBd_1、VGd_2、VBd_3的子像素的极性为负极性，子像素VBd_1与子像素VGd_2的电压强度不同，且子像素VGd_2与子像素的电压强度不同也不同VBd_3，它们共受一列源极驱动信号Vd2驱动驱动。
当然，上述架构也可以为：第二列像素单元的子像素VGd_1、子像素VRd_2、子像素VGd_3的子像素的极性为负极性，它们共受一列源极驱动信号Vd1驱动驱动，VBd_1、VGd_2、VBd_3的子像素的极性为正极性，它们共受一列源极驱动信号Vd2驱动驱动。只要能够确保同一条源极驱动信号在列方向上控制单个像素单元中相邻两列子像素中极性相同且电压强度不同的子像素即可。
本实施例在列方向上控制单个像素单元中相邻两列子像素中极性相同且电压强度不同的子像素，可以减少显示器的集成电路的功耗，可以控制显示器的集成电路的温度的上升。
此外，参考图4，本申请还提出一种显示面板的驱动方法，图4为本申请显示面板的驱动方法一实施例的流程示意图。

需要说明的是，本实施例中的共电驱动电压相对于显示面板的原共电极电压采取正负极性驱动方式进行工作。为方便描述，将显示面板的原共电极电压作为参考电压记作Vcom，将所述第一预设电压记为Vcom1，所述第二预设电压记为Vcom2。

需要说明的是，本实施例的一条扫描信号在行方向上扫描一行子像素。
具体地，在第一帧内接收到所述栅极驱动模块传送的扫描信号时，对扫描到的单个像素单元中第一列子像素和第三列子像素的共电极采用第一预设电压Vcom1进行点反转驱动，此时Vcom1相对于参考电压Vcom较小，所以单个像素单元中第一列子像素和第三列子像素的共电极表现为负极性，即Vcom1表征为负极性驱动电压；例如扫描到的是第一行第二列像素单元，那么就对扫描到的该像素单元中第一列子像素VRd_1和第三列子像素VBd_1的共电极采用第一预设电压Vcom1进行点反转驱动;
同时，第一行第二列像素单元在接收到所述栅极驱动模块传送的上述扫描信号时，对其第二列子像素VGd_1的共电极采用第二预设电压Vcom2进行点反转驱动；此时Vcom2相对于参考电压Vcom较大，所以单个像素单元中第二列子像素的共电极表现为正极性，即Vcom2表征为正极性驱动电压，对单个像素单元中第二列子像素的共电极采用反转后的的Vcom2进行点反转驱动。
步骤S20：在第二帧内将所述第一预设电压的极性进行周期性反转，对所述单个像素单元中第一列子像素和第三列子像素的共电极采用反转后的的第
一预设电压进行点反转驱动；并将所述第二预设电压的极性进行周期性反转，对所述单个像素单元中第二列子像素的共电极采用反转后的的第二预设电压进行点反转驱动。
在具体实现中，在第二帧内，将所述第一预设电压由所述第一极性转化为所述第二极性，执行所述通过第一预设电压对所述单个像素单元中第一列子像素和第三列子像素进行点反转驱动的步骤；然后将所述第二预设电压由所述第二极性转化为所述第一极性，执行所述通过第二预设电压对所述单个像素单元中第二列子像素进行点反转驱动的步骤
具体地，在本实施例中，在第二帧内将所述第一预设电压Vcom1的极性进行周期性反转，对单个像素单元中第一列子像素和第三列子像素的共电极采用反转后的的Vcom1电压进行点反转驱动，此时Vcom1相对于参考电压Vcom较大，所以单个像素单元中第一列子像素和第三列子像素的共电极表现为正极性，即Vcom1表征为正极性驱动电压；并将所述第二预设电压Vcom2的极性进行周期性反转，此时Vcom2相对于参考电压Vcom较小，所以单个像素单元中第二列子像素的共电极表现为负极性，即Vcom2表征为负极性驱动电压，对单个像素单元中第二列子像素的共电极采用反转后的的Vcom2进行点反转驱动。当显示面板的运行一帧图像后，对于某一列像素单元来说，例如第二列像素单元，参考图2，图2中低电压子像素VGd_1、VGd_3、VGd_5由正极性变为负极性驱动，高电压子画素VGd_2、VGd_4、VGd_6由负极性变为正极性驱动，依次类推每列像素单元在显示面板的运行一帧图像后均是如此。
本实施例的显示面板中的显示阵列中相邻像素单元互为高低电压强度穿插排列，所述显示阵列中相邻的子像素的极性不同，同一行子像素的共电极设置两个不同的预设电压，驱动装置在一个驱动周期内根据两个不同的预设电压驱动对显示阵列中的子像素进行点反转驱动，能够在减少显示面板视角色偏的现象出现的几率，显示面板以这种驱动周期运行，能够使得显示面板的视角色偏问题得到改良。
此外，本申请还提出一种显示设备，参考图4，图4是本申请实施例方案涉及的硬件运行环境的显示设备结构示意图；所述显示设备包括显示面板、以及如上所述的显示装置；所述显示面板包括显示阵列，所述显示阵列包括呈阵列排布的像素单元，所述显示阵列中相邻的子像素的极性不同，所述显示阵列中相邻像素单元互为高低电压强度穿插排列所述显示面板的驱动装置包括处理器和存储器，所述存储器存储可执行指令，所述处理器执行所述可执行指令，所述可执行指令包括:
第一驱动模块，设置为以显示面板的两帧运行画面为一驱动周期，在第一帧内对单个像素单元中第一列子像素和第三列子像素的共电极采用第一预设电压进行点反转驱动；并对所述单个像素单元中第二列子像素的共电极采用第二预设电压进行点反转驱动；
第二驱动模块，设置为在第二帧内将所述第一预设电压的极性进行周期性反转，对所述单个像素单元中第一列子像素和第三列子像素的共电极采用反转后的的第一预设电压进行点反转驱动；并将所述第二预设电压的极性进行周期性反转，对所述单个像素单元中第二列子像素的共电极采用反转后的的第二预设电压进行点反转驱动。
其中，所述显示面板可以是液晶显示面板，所述显示设备可以是电脑显示屏、电视机显示屏以及平板电脑显示屏等显示设备。
以上内容是结合具体的优选实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
