Description

显示面板的驱动方法、装置及设备
本申请要求于2019年01月30日提交中国专利局、申请号为201910096420.7、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,可参见图1,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,可参见图1中的理想曲线;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,可参见图1中的实际曲线。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,可参见图2,将形成表征主像素的A曲线以及表征次像素的B曲线,由于将通过主像素与次像素共同来进行显示,所以,将获得图2中的实际曲线。明显地,图2中的实际曲线比之图1中的实际曲线更加接近理想曲线。所以,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。
上述内容仅用于辅助理解本申请的技术方案,并不代表承认上述内容是现有技术。
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、装置及设备,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, 所述像素单元包括第一方向上的第一子像素、第二子像素以及第三子像素,所述像素单元的三个子像素根据排列的顺序分别在所述第一方向上对齐;所述显示面板的驱动方法包括:
以扫描完第二方向上的两个相邻的子像素为数据驱动周期,在接收到数据驱动电路输入的数据驱动信号时,在所述数据驱动周期内通过所述数据驱动信号分别对所述第二方向上的两个相邻子像素进行依序驱动;以及
在第一时段内对第一相邻子像素进行正极性驱动,在第二时段内对第二相邻子像素进行负极性驱动,其中,所述第一时段与所述第二时段的时长不同。
此外,为实现上述目的,本申请还提出一种显示面板的驱动装置,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, 所述像素单元包括第一方向上的第一子像素、第二子像素以及第三子像素,所述像素单元的三个子像素根据排列的顺序分别在所述第一方向上对齐;所述显示面板的驱动装置包括:
驱动模块,设置为以扫描完第二方向上的两个相邻的子像素为数据驱动周期,在接收到数据驱动电路输入的数据驱动信号时,在所述数据驱动周期内通过所述数据驱动信号分别对所述第二方向上的两个相邻子像素进行依序驱动;以及
所述驱动模块,还设置为在第一时段内对第一相邻子像素进行正极性驱动,在第二时段内对第二相邻子像素进行负极性驱动,其中,所述第一时段与所述第二时段的时长不同。
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:所述显示设备包括:显示面板、存储器、非易失性存储器以及处理器,所述非易失性存储器存储可执行指令,所述处理器执行所述可执行指令。
本申请中为了有效地规避色偏现象,并未重新设计金属走线或者TFT元件,而将在列方向上输入正极性驱动时长与负极性驱动时长不同的数据驱动信号来进行像素单元的驱动,由于正极性驱动时长与负极性驱动时长不同,也就直接控制了对像素单元进行充电的充电时长,充电时长将不同,进而使得充电能力不同,形成了高电压像素单元及低电压像素单元穿插排列,从而改善了色偏。所以,可认为,本申请中在不影响面板透率的前提下成功地改善了色偏现象。

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3,图3为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。
如图3所示,该显示设备可以包括:处理器1001,例如CPU,通信总线1002、用户接口1003,显示面板1004,存储器1005。其中,通信总线1002设置为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。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。
本领域技术人员可以理解,图3中示出的显示设备结构并不构成对显示设备的限定,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3所示,作为一种存储介质的存储器1005中可以包括操作系统、用户接口模块以及显示面板的驱动程序。
在图3所示的显示设备中,本申请显示设备中的处理器1001、存储器1005可以设置在数据驱动集成电路中,所述数据驱动集成电路通过处理器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的操作。
基于上述硬件结构,所述显示面板1004包括显示阵列,所述显示阵列包括呈阵列排布的像素单元,提出本申请显示面板的驱动方法的实施例。
对于显示阵列的结构可参考图4,对于图4中的显示阵列的驱动时序可参考图5。为了实现相邻子像素为高低电压穿插驱动排列方,同一数据电路上的驱动采用点反转式驱动,直接控制各个子像素的数据驱动信号的占空比时长,以控制了扫描驱动信号相对于数据驱动信号正确的充电时间,使得子像素对于实现相同驱动电压的充电能力不同。
可参见图4,列方向上的第一子像素为VGd_1、列方向上的第二子像素为VGd_2、列方向上的第三子像素为VGd_3、列方向上的第四子像素为VGd_4、列方向上的第五子像素为VGd_5以及列方向上的第一六像素为VGd_6。
为了控制扫描驱动信号相对于数据驱动信号的充电时间,正极性子像素VGd_1、VGd_3以及VGd_5的数据驱动时长较长,负极性子像素VGd_2、VGd_4以及VGd_6的数据驱动时长较短,使得负极性子像素VGd_2、VGd_4以及VGd_6的等效充电电压下降形成所谓低电压子像素,使得正极性子像素VGd_1、VGd_3以及VGd_5的等效充电电压维持原充电信号形成所谓高电压子像素。
通过将原本相同的数据驱动时长形成时长长短穿插的一列子像素,来达到高电压子像素充电与低电压子像素充电的差异,进而改善色偏改善。
参照图6,图6为本申请显示面板的驱动方法第一实施例的流程示意图。
其中,所述显示阵列可参见图4,显示阵列的驱动时序可参见图5。
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:以扫描完第二方向上的两个相邻的子像素为数据驱动周期,在接收到数据驱动电路输入的数据驱动信号时,在所述数据驱动周期内通过所述数据驱动信号分别对所述第二方向上的两个相邻子像素进行依序驱动。
在具体实现中,可基于图4中所示的显示阵列以及图5中所示的驱动时序来实现本实施例,具体而言,图5中的上图作为标准驱动时序进行对照,便于理解;图5中的下图用于展示本实施例中的数据驱动电路输入的数据驱动信号、扫描驱动信号以及参考电压,其中,Vcom为参考电压,Vgh为扫描驱动信号的最大值,Vgl为扫描驱动信号的最小值。其中,第一方向可为行方向,第二方向为列方向。
步骤S20:在第一时段内对第一相邻子像素进行正极性驱动,在第二时段内对第二相邻子像素进行负极性驱动,其中,所述第一时段与所述第二时段的时长不同。
可以理解的是,由于扫描驱动信号用于控制像素单元的导通与断开,数据驱动信号用于对像素单元进行充电,但是,数据驱动信号能够进行充电工作的前提为扫描驱动信号已控制像素单元为导通状态。所以,当驱动了列方向上的子像素的各扫描驱动信号相同时,可通过直接控制数据驱动信号对像素单元进行充电的充电时间,来赋予列方向上的第一子像素与第二子像素具有不同的充电能力。
在具体实现中,参见图4,在列方向上的第一子像素可被简记为VGd_1,在列方向上的第二子像素可被简记为VGd_2。参见图5,VGd_1与VGd_2均由一路数据驱动信号来进行充电工作,所以,可设置数据驱动信号中在数据驱动周期内存在交替切换的第一预设电压与第二预设电压,第一预设电压大于参考电压,采用第一预设电压进行正极性驱动;第二预设电压小于参考电压,采用第二预设电压进行负极性驱动。且第一预设电压与第二预设电压所占的时长不同,比如,第一预设电压所占的时长大于第二预设电压所占的时长,考虑到扫描驱动信号Vg1与Vg2相同,则可导致第一预设电压对VGd_1进行正极性驱动的第一时段将大于第二预设电压对VGd_2进行负极性驱动的第二时段。不仅形成了不同极性的子像素,由于驱动时长不同,也导致了VGd_1与VGd_2形成的等效充电电压不同,最终表现为,VGd_1形成为高电压子像素而VGd_2形成为低电压子像素。由于达到高电压子像素充电与低电压子像素充电的差异,形成了高电压像素单元及低电压像素单元穿插排列,从而改善了色偏。
本实施例中为了有效地规避色偏现象,并未重新设计金属走线或者TFT元件,而将在列方向上输入正极性驱动时长与负极性驱动时长不同的数据驱动信号来进行像素单元的驱动,由于正极性驱动时长与负极性驱动时长不同,也就直接控制了对像素单元进行充电的充电时长,充电时长将不同,进而使得充电能力不同,形成了高电压像素单元及低电压像素单元穿插排列,从而改善了色偏。所以,可认为,本实施例在不影响面板透率的前提下成功地改善了色偏现象。
进一步地,所述在第一时段内对第一相邻子像素进行正极性驱动,在第二时段内对第二相邻子像素进行负极性驱动之前,所述显示面板的驱动方法还包括:
在接收扫描驱动电路输入的各扫描驱动信号时,通过所述扫描驱动信号以扫描驱动周期对所述第二方向上的子像素进行驱动,其中,所述数据驱动周期的时长与两个连续的扫描驱动周期的时长相等。
在具体实现中,如图4,对列方向上的子像素进行驱动时的各扫描驱动信号可相同,比如,对VGd_1进行驱动的扫描驱动信号Vg1与对VGd_2进行驱动的扫描驱动信号Vg2为相同的信号,可为图5中所示的扫描驱动信号。
此外,可将一个扫描驱动周期记为1dataT,所以,数据驱动周期的时长为2* dataT。
进一步地,所述数据驱动周期包括第一扫描驱动周期与第二扫描周期,所述第一扫描驱动周期的时长等于所述第二扫描周期;
所述在接收扫描驱动电路输入的各扫描驱动信号时,通过所述扫描驱动信号以扫描驱动周期对所述第二方向上的子像素进行驱动之后,所述显示面板的驱动方法还包括:
当通过所述扫描驱动信号在所述第一扫描驱动周期内对所述第一相邻子像素进行驱动时,在正极性驱动时长内对所述第一相邻子像素采用所述第一预设电压进行正极性驱动,其中,所述正极性驱动时长为在所述数据驱动周期内所述第一预设电压所占的时长,所述正极性驱动时长大于所述第一扫描驱动周期;
当通过所述扫描驱动信号在所述第二扫描驱动周期内对所述第二相邻子像素进行驱动时,在负极性驱动时长内对所述第二相邻子像素采用第二预设电压进行负极性驱动,其中,所述负极性驱动时长为在所述数据驱动周期内所述第二预设电压所占的时长,所述正极性驱动时长大于所述负极性驱动时长,所述负极性驱动时长小于所述第二扫描驱动周期且大于所述第二扫描驱动周期与扫描导通时段之差,所述扫描导通时段为所述扫描驱动周期内对所述第二方向上的子像素进行导通的时段。
在具体实现中,可参见图5,数据驱动周期的时长为2* dataT,数据驱动信号为第一预设电压时所占的时长可称为正极性驱动时长,可记为1dataT+∆t;数据驱动信号为第二预设电压时所占的时长可称为负极性驱动时长,可记为1dataT-∆t,总计为2* dataT。
可以理解的是,为了便于理解数据驱动信号对子像素的驱动原理,可以两个连续的扫描驱动周期进行表述,即以两个连续的dataT时长为例,若参见图5中的下图,在扫描驱动信号的第一个dataT内,数据驱动信号一直为第一预设电压,且由于数据驱动信号的正极性驱动时长1dataT+∆t大于dataT,所以,扫描驱动信号完整地导通了子像素,可将该扫描导通时段记为T1,则充电时长也同为T1;在扫描驱动信号的第二个dataT内,由于数据驱动信号的正极性驱动时长为1dataT+∆t,所以,在扫描驱动信号的第二个dataT内数据驱动信号可为∆t时长的第一预设电压,也可为1dataT-∆t时长的第二预设电压。
应当理解的是,正是因为在扫描驱动信号的第二个dataT内,数据驱动信号的电压发生了跳变。所以,在扫描驱动信号的第二个dataT内,在该周期内的脉冲宽度T1内将会包括数据驱动信号的电压跳变时刻,故而,负极性驱动的驱动时长将小于T1,可记为T1'。其中,第一时段即为T1,第二时段即为T1'。
可以理解的是,正是因为正极性驱动的实际驱动时长为T1,负极性驱动的实际驱动时长为T1',而且,T1大于T1',也就来达到了高电压子像素充电与低电压子像素充电的差异,可将实际驱动时长为T1的第一子像素视为高电压子像素,可将实际驱动时长为T1'的第二子像素视为低电压子像素,进而达成了对于色偏的改善。
进一步地,所述像素单元中任意相邻的子像素分别采用高低电压交替设置。
在具体实现中,可基于点反转(dot inversion)方式进行极性反转,比如,可参考图4,VGd_1为正极性驱动,在VGd_1所处行方向上的左右相邻的子像素均为负极性驱动;VGd_2为负极性驱动,在VGd_2所处行方向上的左右相邻的子像素均为正极性驱动。
进一步地,所述第一子像素、所述第二子像素以及所述第三子像素分别对应为红色子像素、绿色子像素以及蓝色子像素。
在具体实现中,可参考图4,图4中像素单元由三色子像素构成,比如,示意为R的红色子像素、示意为G的绿色子像素以及示意为B的蓝色子像素。
进一步地,所述以扫描完所述第二方向上的两个相邻的子像素为数据驱动周期,在接收到数据驱动电路输入的数据驱动信号时,在所述数据驱动周期内通过所述数据驱动信号分别对所述第二方向上的两个相邻子像素进行依序驱动之后,所述显示面板的驱动方法还包括:
在所述数据驱动周期内第一相邻子像素与第二相邻子像素依序导通时,在第三时段内对所述第一相邻子像素进行负极性驱动,在第四时段内对所述第二相邻子像素进行正极性驱动,其中,所述第三时段与所述第二时段的时长相同,所述第四时段与所述第一时段的时长相同。
在具体实现中,除了图4与图5之外,对于本实施例中的显示阵列的结构也可参考图7,对于图7中的显示阵列的驱动时序可参考图8。区别于图4表示的显示阵列,由于数据驱动信号中同时存在着第一预设电压与第二预设电压,所以,第一预设电压可驱动VGd_1、VGd_3以及VGd_5,第二预设电压可驱动VGd_2、VGd_4以及VGd_6。相应地,也可如图7,第一预设电压也可驱动VGd_2、VGd_4以及VGd_6,第二预设电压也可驱动VGd_1、VGd_3以及VGd_5。
可以理解的是,导致了列方向上的子像素依序为负极性子画素VGd_1、正极性子画素VGd_2、负极性子画素VGd_3、正极性子画素VGd_4、负极性子画素VGd_5以及正极性子画素VGd_6,对应的各子像素的数据驱动时序为T-∆t、T+∆t、T-∆t、T+∆t、T-∆t以及T+∆t,使得各子像素资料驱动信号相对于闸极开关充电时间T1'、T1、T1'、 T1、T1'以及 T1、其中T1'<T1,使得VGd_1、VGd_2、VGd_3、VGd_4、VGd_5、VGd_6等效电压依次呈现高低电压穿差相邻。这样可以实现不同图框时序不同高低电压信号子画素,肉眼就不会明显可以见到高电压子画素与低电压子画素的差异,不会有解析度下降的缺陷。
此外,本申请实施例还提出一种显示面板的驱动装置。如图9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, 所述像素单元包括第一方向上的第一子像素、第二子像素以及第三子像素,所述像素单元的三个子像素根据排列的顺序分别在所述第一方向上对齐;所述显示面板的驱动装置包括:
驱动模块200,设置为以扫描完第二方向上的两个相邻的子像素为数据驱动周期,在接收到数据驱动电路输入的数据驱动信号时,在所述数据驱动周期内通过所述数据驱动信号分别对所述第二方向上的两个相邻子像素进行依序驱动;所述驱动模块200,还设置为在第一时段内对第一相邻子像素进行正极性驱动,在第二时段内对第二相邻子像素进行负极性驱动,其中,所述第一时段与所述第二时段的时长不同。
如图10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设置为输出扫描驱动信号,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,将在第二方向上输入正极性驱动时长与负极性驱动时长不同的数据驱动信号来进行像素单元的驱动,由于正极性驱动时长与负极性驱动时长不同,也就直接控制了对像素单元进行充电的充电时长,充电时长将不同,进而使得充电能力不同,形成了高电压像素单元及低电压像素单元穿插排列,从而改善了色偏。所以,可认为,在不影响面板透率的前提下成功地改善了色偏现象。
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显示面板的驱动程序,所述显示面板的驱动程序被处理器执行如上文所述的显示面板的驱动方法的步骤。

上述本申请实施例序号仅仅为了描述,不代表实施例的优劣。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在如上所述的一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端设备(可以是手机,计算机,服务器,空调器,或者网络设备等)执行本申请各个实施例所述的方法。
