Description

显示面板的驱动方法、装置及设备
本申请要求于2019年1月30日提交中国专利局、申请号为201910094529.7、发明名称为“显示面板的驱动方法、装置、设备及存储介质”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、装置及设备。
背景技术
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,VA液晶在驱动过程中,若以较小的视角观看显示面板,比如,正视,像素的亮度将随电压呈线性变化;若以较大的视角观看显示面板,像素的亮度将随电压快速饱和,造成视角画质恶化严重。明显地,理想曲线与实际曲线存在较大的区别,这使得较大的视角下原本应当呈现的灰阶会因为恶化严重出现了变化,也就导致了色偏。
为了改善VA液晶的色偏问题,一般的解决方案是将子像素进行进一步地划分,分为主像素与次像素,但在划分主像素与次像素后,若以较大的视角观看显示面板,像素的亮度将随电压变化的趋势接近于在以较小的视角观看显示面板时的电压变化趋势。
可是,该种划分主像素与次像素的方式将藉由在空间上给予主次像素不同的驱动电压来解决色偏问题,如此也就导致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。
所以,可认为,现行的色偏解决方式由于将影响面板透率,并不能很好地改善色偏现象。
发明内容
本申请的主要目的在于提出显示面板的驱动方法、装置、设备及存储介质,旨在不影响面板透率时有效地改善色偏现象。
为实现上述目的,本申请提供一种显示面板的驱动方法,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;所述显示面板的驱动方法包括:
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;
以扫描完相邻的两行像素单元为驱动周期,将所述驱动周期中的第一行像素单元中的奇数列像素单元采用所述第一预设扫描驱动信号进行驱动,对所述第一行像素单元中的偶数列像素单元采用所述第二预设扫描驱动信号进行驱动,且对所述驱动周期中的第二行像素单元中的奇数列像素单元采用所述第二预设扫描驱动信号进行驱动,对所述第二行像素单元中的偶数列像素单元采用所述第一预设扫描驱动信号进行驱动。

此外,为实现上述目的,本申请还提出一种显示设备,所述显示设备包括显示面板的驱动装置。
此外,为实现上述目的,本申请还提出一种存储介质,其中,所述存储介质上存储计算机可读指令,其中所述计算机可读指令被处理器执行时,实现如下步骤:
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;
以扫描完相邻的两行像素单元为驱动周期,将所述驱动周期中的第一行像素单元中的奇数列像素单元采用所述第一预设扫描驱动信号进行驱动,对所述第一行像素单元中的偶数列像素单元采用所述第二预设扫描驱动信号进行驱动,且对所述驱动周期中的第二行像素单元中的奇数列像素单元采用所述第二预设扫描驱动信号进行驱动,对所述第二行像素单元中的偶数列像素单元采用所述第一预设扫描驱动信号进行驱动。

具体实施方式
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Vd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集成电路(integrated circuit,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。
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,将所述第一预设扫描驱动信号通过第一预设时间的导通时长进行驱动,且将所述第二预设扫描驱动信号通过第二预设时间的导通时长进行驱动,其中,所述第一预设时间小于所述第二预设时间。
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,所述第二设扫描驱动信号为Vg2,所述第一预设时间为对与所述第一预设扫描驱动信号连接的子像素的导通时间△t1,所述第二预设时间为对与所述第二预设扫描驱动信号连接的子像素的导通时间△t2,其中,△t1<△t2,从而使同列相邻的两个子像素的的充电能力不同,使Vg2连接的子像素的充电能力大于Vg1连接的子像素的充电能力,从而造成同列相邻两个子像素为通过高电压和低电压交替设置。
步骤S20,以扫描完相邻的两行像素单元为驱动周期,将所述驱动周期中的第一行像素单元中的奇数列像素单元采用所述第一预设扫描驱动信号进行驱动,对所述第一行像素单元中的偶数列像素单元采用所述第二预设扫描驱动信号进行驱动,且对所述驱动周期中的第二行像素单元中的奇数列像素单元采用所述第二预设扫描驱动信号进行驱动,对所述第二行像素单元中的偶数列像素单元采用所述第一预设扫描驱动信号进行驱动。
在本实施例中以红色(R)、绿色(G)以及蓝色(B)子像素为一像素单元为例,还可包括更多子像素,例如白色(W),本实施例对此并不限制,为了实现各像素单元采用高低电压穿插驱动排列方式,每一行像素单元中的子像素采用两种扫描驱动线路及驱动信号,同一行像素单元中的的奇数列像素单元与偶数列像素单元采用不同的扫描驱动线路,每一行像素单元中的子像素进行驱动时同时开启两种扫描驱动信号,同时对同一行子像素进行驱动。另外,配合数据驱动信号以左右相邻子像素穿插的驱动线路设计,并对同一极性驱动同一数据驱动线路,减少极性的频繁驱动,从而减少驱动IC的工作,降低了驱动IC的功耗及驱动IC的温度提升风险,达到高电压像素单元及低电压像素单元穿插排列的驱动方式,因此解决了视角色偏问题,在扫描驱动信号切换时,可以实现不同时序的高低电压子像素,由于肉眼就不会明显察觉高电压子像素与低电压子像素的差异,因此避免解析度下降。
可以理解的是,如图3a以及4b的时序图,为了实现以R、G、B子像素为像素单元,使像素单元采用高低电压穿插驱动排列方式,同一行子像素同时设计两种扫描驱动电路,其中一扫描驱动信号为Vg2,如图3a中第一行子像素的偶数列像素单元共扫描驱动线路与扫描驱动信号,另一扫描驱动信号为Vg1,为第一行子像素的奇数列像素单元共扫描驱动线路与驱动信号,如图3b的时序图,控制Vg1的扫描驱动信号的开关时序对于数据驱动信号的相较于与Vg2扫描驱动信号的开关时序对于数据驱动信号较小,可以让与Vg1扫描驱动线路对应的子像素充电能力变差,与Vg2扫描驱动线路对应的子像素充电能力变好,从而达到高电压子像素正常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。另外,配合数据驱动信号以相邻左右子像素穿插的驱动线路设计,使同一极性驱动同一数据驱动线路,减少极性的频繁驱动,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,达到了高电压像素单元及低电压像素单元穿插排列得驱动解决了视角色偏问题。
本实施例对同行像素单元采用两条扫描驱动信号穿插的方式进行驱动,将所述扫描驱动信号中的第一扫描信号的导通时间设为小于第二扫描信号的导通时间,从而使两条扫描驱动信号对应驱动的像素单元的充电时间存在差异,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。
进一步地,所述像素单元包括在行方向和列方向上分别交替设置的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:
将相邻的第一像素单元的各子像素和第二像素单元的各子像素的极性设为相反的极性,且在所述步骤S20之前,所述方法还包括:
对同一列像素单元内的各列子像素采用预设个数据驱动信号进行驱动。
需要说明的是,由于本实施例中数据驱动信号采用左右相邻的子像素穿插驱动排列的方式,同一极性驱动同一数据驱动信号,而无需根据各个子像素的驱动信号的差异设计相应的驱动信号进行驱动,较少IC的驱动频率,达到降频的目的。
所述数据驱动信号包括第一预设数据驱动信号和第二预设数据驱动信号;所述对同一列像素单元内的各列子像素采用预设个数据驱动信号进行驱动,包括:
对同一列像素单元内的各列子像素的奇数行中的第一极性子像素采用第一预设数据驱动信号进行驱动,对同一列像素单元内的各列子像素的偶数行中的第二极性子像素采用第二预设数据驱动信号进行驱动。
进一步地,所述步骤S20之后,所述方法还包括:
对同一列像素单元中同列的两个相邻子像素采用第三预设数据驱动信号进行驱动,所述第三预设数据驱动信号为相邻的两个子像素的历史驱动信号的平均值。
需要说明的是,所述相邻的两个子像素的历史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'则可以优选为原像素信号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,则可以优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'。
进一步地,对同列子像素采用不同预设时间的导通时长进行导通,其中,所述预设时间为所述第二预设时间和第一预设时间交替设置。
如图3b时序,图中Vd1数据驱动信号中G正极性子像素VGd_1、VGd_3、VGd_5对应于扫描驱动电压为Vg2及R正极性子像素VRd_2、VRd_4、VRd_6对应的扫描驱动电压为Vg1,Vd2数据驱动信号中G负极性子像素VGd_2、VGd_4、VGd_6对应的扫描驱动电压为Vg1,及B负极性子像素VBd_1、VBd_3、VBd_5对应的扫描驱动电压为Vg2,其中Vg1的扫描驱动信号的开关时序△t1对于数据驱动信号的相较于与Vg2扫描驱动信号的开关时序△t2于数据驱动信号较小,即△t1 <△t2。
如图3b所示,Vd1驱动信号依序为G正极性驱动及R正极性驱动,Vd1=VG1、VR1、VG2、VR2、VG3、VR3…,配合扫描驱动信号分别Vg2_1、Vg1_2、Vg2_3、Vg1_4、Vg2_5、Vg1_6,且扫描驱动信号的开关时序分别依序为△t2、△t1、△t2、△t1、△t2、△t1,同时间Vd2驱动信号依序为B负极性驱动及G负极性驱动,Vd2=VB1'、VG1'、VB2'、VG2'、VB3'、VG3'…,配合扫描驱动信号分别Vg2_1、Vg1_2、Vg2_3、Vg1_4、Vg2_5、Vg1_6,扫描驱动信号的开关时序分别依序为△t2、△t1、△t2、△t1、△t2、△t1,其中扫描驱动信号的开关时序△t1 <△t2,可以实现以RGB子像素为像素单元的高电压像素单元及低电压像素单元信号穿插排列。
进一步地,获取反转信号,根据所述反转信号将所述第一扫描驱动信号与所述第二扫描驱动信号的导通时长进行切换。
随著相邻数据驱动信号的反转,扫描驱动信号的开关时序对于数据驱动信号△t1、△t2亦配合切换,即Vg1的扫描驱动信号的开关时序对于数据驱动信号为△t2,Vg2的扫描驱动信号的开关时序对于资料驱动信号为△t1,从而可实现不同时序不同高低电压信号子像素,由于肉眼无法明显见到高电压子像素与低电压子像素的差异,因此避免了解析度下降。
进一步地,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扫描驱动信号示意图,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。
此外,本申请实施例还提出一种显示面板的驱动装置。如图6所示,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;所述显示面板的驱动装置包括:
获取模块110,设置为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;

如图7所示,所述显示面板的驱动装置还包括显示阵列100和驱动模块200,所述驱动模块200可以包括扫描单元210和驱动单元220,扫描单元210用于输出扫描驱动信号,一般是逐行对像素单元进行扫描,驱动单元220则输出数据驱动信号,使像素单元在被扫描到时接收驱动数据进行显示。
驱动模块200可以参考上述实施例,经过该处理,对同行像素单元采用两条扫描驱动信号穿插的方式进行驱动,将所述扫描驱动信号中的第一扫描信号的导通时间设为小于第二扫描信号的导通时间,从而使两条扫描驱动信号对应驱动的像素单元的充电时间存在差异,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。
此外,本申请实施例还提出一种存储介质,所述存储介质上存储有计算机可读指令,其中所述计算机可读指令被处理器执行时实现上述显示面板的驱动方法。
以上仅为本申请的优选实施例,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
