Description

显示面板的驱动方法及显示设备
本申请要求于2019年1月30日提交中国专利局、申请号为201910095053.9、发明名称为“显示面板的驱动方法及显示设备”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
本申请涉及液晶显示技术领域，尤其涉及显示面板的驱动方法及显示设备。
 背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
现行的大尺寸液晶显示面板多半为负型垂直排列（Vertical Alignment，VA）液晶或者平面转换（In-Plane Switching，IPS）液晶，将VA液晶技术与IPS液晶技术进行比对可以发现，VA液晶技术具有较高的生产效率以及较低的制造成本，但是在光学性质的表现上差于IPS液晶技术，存在较为明显的光学性质缺陷，尤其是在适用于大尺寸的显示面板时，为了改善VA液晶的色偏问题，将子像素进行在一实施例中划分，分为主像素与次像素，该种划分在设计像素时需要再次设计金属走线或者薄膜晶体管（Thin Film Transistor，TFT）元件以驱动次像素，这将造成可透光开口区牺牲，进而影响面板透率。

 本发明的实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
参照图1，图1为本发明实施例方案涉及的硬件运行环境的显示面板结构示意图。
如图1所示，该显示面板可以包括：处理器1001，例如CPU，通信总线1002、用户接口1003，网络接口1004，存储器1005。其中，通信总线1002用于实现这些组件之间的连接通信。用户接口1003可以包括显示屏（Display）、输入单元比如键盘（Keyboard），可选用户接口1003还可以包括标准的有线接口、无线接口。网络接口1004可选的可以包括标准的有线接口、无线接口（如WI-FI接口）。存储器1005可以是高速RAM存储器，也可以是稳定的存储器（non-volatile memory），例如磁盘存储器。存储器1005可选的还可以是独立于前述处理器1001的存储装置，所述显示面板1006可为液晶显示面板，还可为其他可实现相同或相似功能的显示面板。
本领域技术人员可以理解，图1中示出的显示面板结构并不构成对显示面板的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图1所示，作为一种存储介质的存储器1005中可以包括操作系统、网络通信模块、用户接口模块以及显示面板的驱动程序。
在图1所示的显示面板中，网络接口1004主要用于连接网络，与互联网进行数据通信；用户接口1003主要用于连接用户终端，与终端进行数据通信；本发明显示面板通过处理器1001调用存储器1005中存储的显示面板的驱动程序并执行显示面板的驱动方法。
基于上述硬件结构，提出本发明显示面板的驱动方法实施例。
参照图2a为示例的显示阵列的结构示意图，原液晶显示面板设计扫描驱动信号通过同一行子像素，并且各行扫描驱动信号如附图2b示例的显示阵列的驱动时序示意图，其中Vg1、Vg2、Vg3等表示各行扫描驱动信号的驱动电压相同，扫描驱动信号相对于数据驱动信号时序上对应的相对时序及重叠时间均相同，因此各子像素有相同的充电能力。为解决色偏问题，驱动上需采用高电压子像素与低电压子像素穿插达成色偏改善的效果，因此，数据驱动电压Vgd需根据每个子像素的需求高低电压依序驱动，如图2a上的高电压子像素驱动电压VGd_1，次一相邻低电压子像素VGd_2，同一列子像素依序高电压及低电压子像素信号驱动，除了驱动信号上的差异，如果再配合两邻子像素驱动极性相异，随著面板解析度的提高，同一行子像素数目的增加，会使得驱动频率增加增加驱动IC的负载，增加了驱动IC的功耗及驱动IC温度提升的风险。
参照图3a为本实施例显示阵列一实施例的结构示意图，图3b为本实施例显示阵列对应的驱动时序示意图，所述显示阵列的显示面板可为液晶显示面板，还可为其他可实现相同或相似功能的显示面板，本实施例对此不作限制，在本实施例中，以液晶显示面板为例进行说明，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，所述像素单元包括第一像素单元和第二像素单元，所述第一像素单元和第二像素单元在第一方向上和在第二方向上交替设置，所述像素单元包括第一子像素、第二子像素以及第三子像素，所述第一子像素、第二子像素以及第三子像素分别对应为红色子像素（R）、绿色子像素（G）以及蓝色子像素（B），其中，所述第一方向为行方向，所述第二方向为列方向，所述第一像素单元和第二像素单元极性相反。
参照图4，图4为本发明显示面板的驱动方法第一实施例的流程示意图。
在第一实施例中，所述显示面板的驱动方法包括以下步骤：
步骤S10，获取第一预设扫描驱动信号与第二预设扫描驱动信号，所述第一预设扫描驱动信号的导通时长小于所述第二预设扫描驱动信号的导通时长以使所述第一预设扫描驱动信号对应于所述预设数据驱动信号的驱动时间小于所述第二预设扫描驱动信号对应于所述预设数据驱动信号的驱动时间。
需要说明的是，如图3a所示，所述第一预设扫描驱动信号为Vg1，所述第二预设扫描驱动信号为Vg2，所述第一预设扫描驱动信号的导通时间为△t1，所述第二预设扫描驱动信号的导通时间为△t2，△t1＜△t2，Vgh1表示第一扫描驱动信号的高电压信号，Vgl1表示第一扫描驱动信号的低电压信号，Vgh2表示第二扫描驱动信号的高电压信号，Vgl2表示第二扫描驱动信号的低电压信号。
步骤S20，以扫描完相邻的两行子像素为驱动周期，将所述驱动周期中的第一行像素单元中的偶数列子像素和相邻一行像素单元中的奇数列子像素采用所述第一预设扫描驱动信号进行驱动。
需要说明的是，如图3a所示以及对应的3b驱动时序所示，为了实现相邻R、G、B子像素为高低电压穿插驱动排列方式，Vg1为一行偶数列子像素与相邻一行奇数列子像素共扫描驱动线路与扫描驱动信号，Vg2为同Vg1为一行奇数列子像素与相邻一行偶数列子像素共扫描驱动线路与扫描驱动信号，如图3b驱动时序，由于将同行和同列的两个相邻子像素的极性设为相反的极性，对所述同行和同列的子像素采用点反转的驱动方式进行驱动，控制Vg1的导通时间对于数据驱动信号的相较于与Vg2的导通时间对于数据驱动信号较小，从而使Vg1扫描驱动信号对应的子像素充电能力变差，与Vg2扫描驱动信号对应的子像素充电能力变强，从而达到高电压子像素充电与低电压子像素次充电的目的，进而达成色偏改善的效果。
步骤S30，对所述驱动周期中的第一行像素单元中的奇数列子像素和相邻一行像素单元中的偶数列子像素采用所述第二预设扫描驱动信号进行驱动。
可以理解的是，控制Vg1扫描开关时序相对于数据驱动信号的充电信号相较于Vg2的扫描开关时序相对于数据驱动信号的导通时间较短，可使Vg1扫描驱动线路对应的子像素充电能力变差，与Vg2扫描线路对应的子像素充电能力变强，从而达到高电压子像素充电与低电压子像素充电的差异，进而达成色偏改善的效果。
本实施例通过获取第一预设扫描驱动信号与第二预设扫描驱动信号，所述第一预设扫描驱动信号的导通时长小于所述第二预设扫描驱动信号的导通时长，将驱动周期中的第一行像素单元中的偶数列子像素和相邻一行像素单元中的奇数列子像素采用所述第一预设扫描驱动信号进行驱动，以及第一行像素单元中的奇数列子像素和相邻一行像素单元中的偶数列子像素采用所述第二预设扫描驱动信号进行驱动，从而使两条扫描驱动信号的导通时长存在差异，使两条扫描驱动信号上的子像素的充电能力不同，实现相邻子像素采用高低电压穿插排列的驱动方式进行驱动，从而达到减少色偏的目的。
在一实施例中，所述步骤S10之前，所述方法还包括：
将扫描所述像素单元中同行子像素的第一预设扫描驱动信号与第二预设扫描驱动信号采用穿插排列的方式进行设置，以使同行子像素共用所述第一预设扫描驱动信号和第二预设扫描驱动信号，并且在所述步骤S20之后，所述方法还包括：
获取预设数据驱动信号，将所述像素单元中同列的两个相邻子像素采用同一预设数据驱动信号进行驱动。
可以理解的是，如图3b所示，G行的子像素正极性驱动信号为VG1、VG2、VG3…..，负极驱动性动信号为VG1'、VG2'、VG3'…。当进行驱动时，高电压子像素的等效驱动电压VGd_1，即为正极性驱动信号Vgd=VG1对应于Vg2扫描驱动信号的开关时序△t2，次一相邻低电压子像素VGd_2即为负极性驱动电压Vgd=VG1' ，对应于Vg1的扫描驱动信号的开关时序△t1，△t1＜△t2，等效驱动电压VGd_1> VGd_2。同理，高电压子像素等效驱动电压VGd_3即为正极性驱动信号Vgd=VG2对应于Vg2扫描驱动信号的开关时序△t2，次一相邻低电压子像素VGd_4即为负极性驱动电压Vgd=VG2' 对应于Vg1的扫描驱动信号的开关时序△t1，△t1＜△t2，等效驱动电压VGd_3> VGd_4，从而使同列相邻子像素采用高低电压穿插排列的驱动方式进行驱动，达到减少色偏的目的。
在一实施例中，所述获取预设数据驱动信号，将所述像素单元中同列的两个相邻子像素采用同一预设数据驱动信号进行驱动之前，所述方法还包括：
获取同列的两个相邻子像素的历史驱动信号，将所述预设数据驱动信号设置为所述历史驱动信号的平均值。
需要说明的是，所述历史驱动信号为历史同列相邻的两个子像素的驱动信号为改进前的同列相邻的两个子像素的驱动信号，对同列相邻两个子像素的等效驱动电压VGd_1与VGd_2的等效电压分别以正极性驱动电压Vgd=VG1与负极性驱动电压Vgd=VG1'驱动，正极性驱动电压VG1与负极性驱动电压VG1'则可选为原像素信号Gd1与Gd2信号的平均信号，以 8 bit驱动信号来说为0~255信号，亦即G1=( Gd1+Gd2)/2，G1信号对应的正极性驱动电压VG1及负极性驱动电压VG1'。VGd_3与VGd_4等效电压分别以正极性驱动电压Vgd=VG2与负极性驱动电压Vgd=VG2'驱动，则可选为原图框像素信号Gd3与Gd4信号的平均信号，以 8 bit驱动信号来说为0~255信号，亦即G2=( Gd3+Gd4)/2，G2信号对应的正极性驱动电压VG2及负极性驱动电压VG2'，从而达到降频的目的。
在一实施例中，所述步骤S10之后，所述方法还包括：
接收反转信号，根据所述反转信号将第一预设扫描驱动信号、第二预设扫描驱动信号以及预设数据驱动信号进行反转，得到反转后的第一预设扫描驱动信号、反转后的第二预设扫描驱动信号以及反转后的预设数据驱动信号，以使所述反转后的第一预设扫描驱动信号的导通时长大于所述反转后的第二预设扫描驱动信号的导通时长。
继续如3b时序，图中G列子像素，其中R与B列子像素均相同，高电压子像素VGd_1、VGd_3、VGd_5对应的扫描驱动电压为Vg2与低电压子像素素VGd_2、VGd_4、VGd_6对应的扫描驱动电压为Vg1，其中Vg1扫描驱动信号的开关时序对于数据驱动信号的充电信号相较于与Vg2扫描驱动信号的开关时序对于数据驱动信号的充电信号时间较短。
在本实施例中随著驱动信号的反转，扫描驱动信号开关对于数据驱动信号△t1 、△t2 亦可配合切换，亦即Vg1的扫描驱动信号开关时序对于数据驱动信号为△t2，Vg2的扫描驱动信号开关时序对于数据驱动信号为△t1，从而可实现不同时序不同高低电压信号的子画像素，并且肉眼不会明显见到高电压子像素与低电压子像素的差异，因此，不会出现解析度下降的问题。
在一实施例中，所述步骤S10之后，所述方法还包括：
将所述第一预设扫描驱动信号中的高电压驱动信号以及所述第二预设扫描驱动信号中的高电压驱动信号采用不同的驱动电压进行驱动，将所述第一预设扫描驱动信号中的低电压驱动信号以及所述第二预设扫描驱动信号低电压驱动信号采用不同的驱动电压进行驱动。
如图5所示提供显示阵列另一实施例的结构示意图，除了调整扫描信号的导通时间外，还可调整扫描驱动信号的来达到不同的充电效果，如图5，第一扫描驱动信号的高电压Vgh1与第二扫描驱动信号的高电压Vgh2不同，第一扫描驱动信号的低电压Vgl1与第二扫描驱动信号的高电压Vgl2不同，从而形成削角对压va1与va2，由于现实面板有寄生电容造成扫描驱动信号失真，因此需相应的削角电设计来达到面内均匀度的提升，由于va1与va2不同，即△t1_1/ △t1_2与△t2_1/ △t2_2不同，从而造成同列相邻的像素单元的充电能力不同，实现同列相邻像素单元采用高电压像素单元和低电压像素单元穿插排列的驱动方式进行驱动，从而达到减少色偏的目的。
参照图6a所示提供显示阵列再一实施例的结构示意图以及6b所示提供显示阵列另一实施例的时序驱动示意图，所述步骤S10之前，所述方法还包括：
将同行和同列的两个相邻子像素的极性设为相反的极性，对所述同行和同列的子像素采用点反转的驱动方式进行驱动；或将同行的两个相邻子像素的极性设为相反的极性，以及将同列的两个相邻子像素的极性设为相同的极性，对所述同行的子像素和同列的子像素采用列反转的驱动方式进行驱动。
如图6a所示提供显示阵列另一实施例的结构示意图以及6b所示提供显示阵列另一实施例的时序驱动示意图，本实施例同一列数据驱动方式为采用同一极性驱动，G行的子像素正极性驱动信号Vgd=VG1、VG2、VG3…..，子像素负极性动信号Vgd=VG1'、VG2'、VG3'…。当进行驱动时，高电压子像素等效驱动电压VGd_1即为正极性驱动信号Vgd=VG1与Vg2扫描开关时序△t2的充电时序，次一相邻低电压子像素VGd_2即为正极性驱动电压Vgd=VG1 与Vg1扫描驱动信号的开关时序△t1的充电时序，其中△t1 ＜△t2，等效驱动电压VGd_1> VGd_2。同理，高电压子像素等效驱动电压VGd_3即为正极性驱动信号Vgd=VG2与Vg2闸极开关时序△t2的充电时序，次一相邻低电压子像素VGd_4即为正极性驱动电压Vgd=VG2 与Vg1闸极开关时序△t1的充电时序，其中△t1 ＜△t2，等效驱动电压VGd_3> VGd_4，从而使同列相邻子像素采用高低电压穿插排列的驱动方式进行驱动，达到减少色偏的目的。
参照图7所示提供显示阵列再一实施例的结构示意图，所述像素单元包括第一像素单元和第二像素单元，所述步骤S10之前，所述方法还包括：
将所述第一像素单元和第二像素单元在列方向上交替设置，其中，所述第一像素单元包括行方向上依序排列红色子像素、绿色子像素、蓝色子像素以及白色子像素，第二像素单元包括行方向上依序排列蓝色子像素、白色子像素、红色子像素以及绿色子像素。
如图7所示，提出以WRGB子像素做为高低电压驱动改善色偏的方式，对同行子像素采用Vg1和Vg2穿插排列的方式进行驱动，并且同列子像素采用预设数据驱动信号Vgd进行驱动，同列和同行相邻子像素的极性相反，以WRGB各子像素高低电压穿插排列，并采用点反转的驱动方式进行反转，从而实现四个子像素的高电压子像素与低电压子像素穿插的排列方式，从而使同列相邻子像素采用高低电压穿插排列的驱动方式进行驱动，达到减少色偏的目的。
如图8所示，提出以WRGB子像素做为高低电压驱动改善色偏的方式，对同行子像素采用Vg1和Vg2穿插排列的方式进行驱动，并且同列子像素采用预设数据驱动信号Vgd进行驱动，同列相邻子像素的极性相同且同行相邻子像素的极性相反，以WRGB各子像素高低电压穿插排列，并采用列反转的驱动方式进行反转，从而实现四个子像素的高电压子像素与低电压子像素穿插的排列方式，从而使同列相邻子像素采用高低电压穿插排列的驱动方式进行驱动，达到减少色偏的目的。
