Description

显示面板的驱动方法及装置
本申请要求于2019年1月30日提交中国专利局、申请号为201910098294.9、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及装置。
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。

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。
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、第二预设扫描驱动信号以及预设数据驱动信号,将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进行缩短。
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,所述预设数据驱动信号为Vgd,将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进行缩短,如图3b中的T’,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改进前的驱动时间T,从图中可知,将Vg2相对于预设数据驱动信号的相对驱动时间往前调整了△t,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小于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子像素为驱动周期,将所述驱动周期内的第一行中的奇数列子像素和第二行中的偶数列子像素采用所述第一预设扫描驱动信号进行驱动,且对所述驱动周期中的第一行中的偶数列子像素和第二行中的奇数列子像素采用所述第二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4b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,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,本实施例采用点反转的数据驱动方式,控制扫描驱动信号相对于数据驱动信号时间,Vg2相对于数据驱动信号Vgd的驱动时间相较于Vg1相对于数据驱动信号Vgd的驱动时间提前了△t,使得Vg2扫描驱动信号相对于数据驱动信号Vgd的充电时间T’少于 Vg1扫描驱动信号相对于数据驱动信号Vgd的充电时间T,使得该对应子像素的等效充电电压下降形成所谓低电压子像素。
可以理解的是,控制Vg2的扫描开关时序相对于数据驱动信号的充电信号时间较短,相较于与Vg1扫描开关时序相对于数据驱动信号的充电信号时间较长,可使Vg2扫描驱动线路对应的子像素充电能力变差,与Vg1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。
本实施例采用两条扫描驱动信号对相邻两行的子像素采用穿插的方式进行驱动,将所述扫描驱动信号中的预设扫描驱动信号采用相对于预设数据驱动信号的目标驱动时间进行驱动,从而使两条扫描驱动信号的驱动时间存在差异,使两行扫描驱动信号上的子像素的充电能力不同,实现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,从而达到减少色偏的目的。
可选地,所述步骤S10之前,所述方法还包括:
将相邻两个子像素的极性设为相反的极性,并且在所述步骤S20之后,所述方法还包括:
将同列子像素采用同一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Frame1图框时序时,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与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时间较长,次一相邻低电压子像素VGd_2即为负极性驱动电压Vgd=VG1' ,与Vg2的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,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时间较长,次一相邻低电压子像素VGd_4即为负极性驱动电压Vgd=VG2' 与Vg2的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,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。
可选地,所述将同列子像素采用同一数据驱动信号进行驱动之后,所述方法还包括:
对同列的两个相邻子像素采用所述预设数据驱动信号进行驱动,所述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'。
可选地,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所述第一预设扫描驱动信号和所述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和反转后的预设数据驱动信号,将反转后的第一预设扫描驱动信号的驱动时间进行缩短,以使所述第一预设扫描驱动信号对应于反转后的预设数据驱动信号的驱动时间缩短。
继续如4b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Vg1与低电压子像素素VGd_2、VGd_4、VGd_6对应的扫描驱动电压为Vg2,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VG1时间较长,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VG1'时间较短。
在本实施例中随著相邻两图框驱动信号的反转,如图5,扫描驱动信号的开关对于数据驱动信号充电时间的控制切换,亦即Vg1扫描驱动信号的开关时序对于数据驱动信号的正确充电信号VG1'时间较短,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VG1时间较短长,这样可以实现时序不同高低电压信号子像素,肉眼就不会明显可以见到高电压子像素与低电压子像素的差异,不会有解析度下降的缺陷。
可选地,所述像素单元包括第一像素单元和第二像素单元,在列方向上,所述第一像素单元和所述第二像素单元交替设置,其中,所述第一像素单元为依序排列的红色子像素、绿色子像素、蓝色子像素以及白色子像素,所述第二像素单元包括依序排列的蓝色子像素、白色子像素、红色子像素以及绿色子像素。
可选地,所述步骤S20,包括:
以扫描完相邻的两行子像素为驱动周期,将所述驱动周期内的第一行中的红色子像素和蓝色子像素,以及第二行中的白色子像素和绿色子像素采用所述第一预设扫描驱动信号进行驱动,且将所述驱动周期内的第一行中的绿色子像素和白色子像素,以及第二行中蓝色子像素和红色子像素采用所述第二预设扫描驱动信号进行驱动。
如图6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,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。

驱动模块200可以参考上述实施例,经过该处理,采用两条扫描驱动信号对相邻两行的子像素采用穿插的方式进行驱动,将所述扫描驱动信号中的预设扫描驱动信号采用相对于预设数据驱动信号的目标驱动时间进行驱动,从而使两条扫描驱动信号的驱动时间存在差异,使两行扫描驱动信号上的子像素的充电能力不同,实现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,从而达到减少色偏的目的。
