Description

像素结构及显示面板 技术领域
本申请涉及显示技术领域，具体涉及一种像素结构及显示面板。
背景技术
数据线共用(DLS，Data Line Sharing)的像素架构是像素结构中普遍使用的一种节省覆晶薄膜(COF，Chip On Film)进而降低成本的像素架构，如图1所示，这种像素架构是指同一行相邻两个子像素由同一条数据线供电，例如，数据线DL1同时为位于同一行且相邻的子像素R11、子像素G12充电，数据线DL2为位于同一行且相邻的子像素B13、子像素R14充电，数据线DL3为位于同一行且相邻的子像素G15、子像素B16充电；通过两条栅极线先后开启同一行中的对应子像素，例如，栅极线GL1可以用于开启子像素R11、子像素B13、子像素G15，栅极线GL2可以用于开启子像素G12、子像素R14、子像素B16。
也正是由于上述这种同一行子像素存在先后开启的情况，导致同一行相邻的两个像素会有前后开启的时间差，在静止画面情况下，这种时间差在人眼上亮度叠加，人眼并不能分辨出这种亮度差异；但当播放动态画面或者人在摇头观看的情况下，亮、亮或暗、暗的像素相叠加，人眼就会捕捉到条纹或网格状的现象即摇头纹，它会给人不好的视觉观感。当不同的像素亮度有差异的情况下，这种条纹或网格状的现象会变得更加明显。

在本公开中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一特征和第二特征直接接触，也可以包括第一特征和第二特征不是直接接触而是通过它们之外的第三特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征的水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征的水平高度小于第二特征。
如图2所示的DLS像素架构包括第一行子像素和第二行子像素，第一行子像素中，自左而右的第一个子像素通过下接方式连接至数据线DL1，自左而右的第二个子像素通过上接方式连接至数据线DL1；自左而右的第三个子像素 通过下接方式连接至数据线DL2，自左而右的第四个子像素通过上接方式连接至数据线DL2；自左而右的第五个子像素通过上接方式连接至数据线DL3，自左而右的第六个子像素通过下接方式连接至数据线DL3；自左而右的第七个子像素、第八个子像素、第九个子像素、第十个子像素、第十一个子像素以及第十二个子像素依次分别重复第一个子像素至第六个子像素的连接方式。扫描线GL1可以连接至第一行子像素中的第一个子像素、第三个子像素、第五个子像素、第七个子像素等等，扫描线GL2可以连接至第一行子像素中的第二个子像素、第四个子像素、第六个子像素、第八个子像素等等。扫描线GL1中的扫描信号可以先控制对应的子像素进行充电，然后扫描线GL2中的扫描信号再控制对应的子像素进行充电；或者，两者充电先后顺序可以对调。
在第二行子像素中，自左而右的第一个子像素通过下接方式连接至数据线DL2，自左而右的第二个子像素通过上接方式连接至数据线DL2；自左而右的第三个子像素通过下接方式连接至数据线DL3，自左而右的第四个子像素通过上接方式连接至数据线DL3；自左而右的第五个子像素通过上接方式连接至数据线DL4，自左而右的第六个子像素通过下接方式连接至数据线DL4；自左而右的第七个子像素、第八个子像素、第九个子像素、第十个子像素、第十一个子像素以及第十二个子像素依次分别重复第一个子像素至第六个子像素的连接方式。扫描线GL3可以连接至第二行子像素中的第一个子像素、第三个子像素、第五个子像素、第七个子像素等等，扫描线GL4可以连接至第一行子像素中的第二个子像素、第四个子像素、第六个子像素、第八个子像素等等。扫描线GL3中的扫描信号可以先控制对应的子像素进行充电，然后扫描线GL4中的扫描信号再控制对应的子像素进行充电；或者，两者充电先后顺序可以对调。
其中，第一行子像素中第二个子像素、第五个子像素和第二行子像素中第二个子像素、第五个子像素均以上接方式连接至对应的数据线，再加上不同的子像素所受到的耦合电容不同，导致类同于第二个子像素、第五个子像素这样的子像素所受到的耦合电容较大，所受到的馈路电压也就大，所导致的摇头纹现象也越严重。
如图3所示的DLS像素架构与图2所示的DLS像素架构类似，各子像素 至对应数据线的连接方式也相同，不同的是两者的极性翻转方式。
其中，R可以用于表征红色子像素，G可以用于表征绿色子像素，B可以用于表征蓝色子像素。
需要进行说明的是，经过长期研究发现，通过实验对比图2和图3两个机种的纯色画面，观察到两个机种的纯绿画面时摇头纹现象最明显，而图3所示机种的蓝色画面时摇头纹现象最轻微，图2所示机种的红色画面时摇头纹现象最轻微。如图3所示的机种在L127灰阶下，绿色子像素、红色子像素、蓝色子像素的亮度比例为14：4：1，而通过分析图5中的等效电路可知，扫描线GL2对连接至扫描线GL1的子像素的像素电极11有较大的耦合电容Cpg1，而扫描线GL3对连接至扫描线GL2的子像素的像素电极12因为距离较远只有较小的耦合电容Cpg2。图3所示的像素架构中，一个周期中的4个像素即第一行子像素中自左至右的第一个子像素至第十二子像内，绿色子像素刚好全部都受到较大的耦合电容Cpg1，蓝色子像素都受到较小的耦合电容Cpg2，根据扫描线关闭引起的馈路电压Vft＝(Cgs+Cpg)/Ctotal可知，绿色子像素所受的馈路电压最大，蓝色子像素所受的馈路电压最小；其中，Ctotal为与所有子像素相关的电容之和，例如，其可以为液晶电容Clc、栅源极电容Cgs以及存储电容Cst之和。同理，图2所示的机种，绿色子像素同样所受的馈路电压最大，红色子像素所受的馈路电压最小。
有鉴于此，本实施例提供一种像素结构，如图4所示，该像素结构包括沿第一方向DR1依次排列的多条数据线、沿第二方向DR2依次排列的多条扫描线以及沿第二方向DR2依次排列的多个像素行，第一方向DR1与第二方向DR2相互垂直；每一像素行均位于两条相邻的扫描线之间，相邻的两个像素行之间具有两条扫描线；像素行包括多个沿第一方向DR1依次排列的第一像素单元110，第一像素单元110包括位于同一行且沿第一方向DR1依次排列的六个子像素，相邻的两条数据线之间具有两个子像素，位于相邻的两条数据线之间的两个子像素与同一条数据线连接；在同一个第一像素单元110中，同一灰阶下亮度最大的子像素均连接至第一像素单元110所在的像素行的下一级的扫描线。
可以理解的是，本实施例提供的像素结构，通过第一像素单元110所在的 像素行的下一级的扫描线与在同一个第一像素单元110中同一灰阶下亮度最大的子像素连接，可以降低该同一灰阶下亮度最大的子像素所受到的耦合电容，进而减小该同一灰阶下亮度最大的子像素所受到的馈路(Feed-through)电压，从而减轻了视觉上的摇头纹现象。

在其中一个实施例中，第四扫描线还与第十子像素连接。
可以理解的是，第二像素单元120的构造改进原理与第一像素单元110的改进原理类似，同理可知，第二像素单元120中各子像素所受到的馈路电压同样得以降低，进而改善了摇头纹现象。

在其中一个实施例中，本实施例提供一种显示面板，其包括上述至少一实施例中的像素结构，该显示面板为液晶显示面板。
可以理解的是，本实施例提供的显示面板，通过第一像素单元110所在的 像素行的下一级的扫描线与在同一个第一像素单元110中同一灰阶下亮度最大的子像素连接，可以降低该同一灰阶下亮度最大的子像素所受到的耦合电容，进而减小该同一灰阶下亮度最大的子像素所受到的馈路(Feed-through)电压，从而减轻了视觉上的摇头纹现象。
其中，需要说明的是，图1至图4中的实心原点仅代表子像素分别与对应的数据线、扫描线连接，并不表示对应的数据线、扫描线发生了直接连接。
本实施例提供了一种像素结构，如图4所示，该像素结构包括至少一个像素单元100、沿第二方向DR2依次排布的第一扫描线、第二扫描线以及第三扫描线以及沿第一方向DR1依次排布的第一数据线、第二数据线以及第三数据线。

第一子像素、第二子像素在第一方向DR1上位于第一数据线与第二数据线之间，第三子像素、第四子像素在第一方向DR1上位于第二数据线与第三数据线之间，且第一数据线下接于第二子像素，第三数据线下接于第五子像素。
可以理解的是，本实施例提供的像素结构及显示面板，通过第一数据线、第三数据线分别下接于亮度较高的第二子像素、第五子像素，可以降低第二子像素、第五子像素所受到的耦合电容，进而减小第二子像素、第五子像素所受到的馈路(Feed-through)电压，从而减轻了视觉上的摇头纹现象。
在其中一个实施例中，第一数据线上接于第一子像素，第二数据线上接于第三子像素，第二数据线下接于第四子像素，第三数据线上接于第六子像素。
需要进行说明的是，由于第一子像素、第三子像素、第四子像素以及第六子像素分别至对应数据线的连接方式均进行了改造，使得第一子像素、第三子 像素、第四子像素以及第六子像素所受到的耦合电容得到了降低，进而减小了第一子像素、第三子像素、第四子像素以及第六子像素所受到的馈路电压Vft。各子像素对应的馈路电压的改善具体参见下表1：

  第一子像素 第二子像素 第三子像素 第四子像素 第五子像素 第六子像素
改善前Vft 0.901V 0.941V 0.885V 0.928V 0.929V 0.899V
改善后Vft 0.850V 0.842V 0.849V 0.842V 0.845V 0.855V
通过上表可以得知：相对于各子像素的改善前馈路电压Vft，各对应子像素的改善后馈路电压Vft均得到了对应下降，对应地，可以改善摇头纹现象。其中，在一个循环周期内，改善前，第二子像素的馈路电压Vft最大为0.941V；改善后，第五子像素的馈路电压Vft最大为0.845V。由于第二子像素、第五子像素均可以但不限于为绿色子像素，例如，在其他子像素的排列方式中也可以为红色子像素或者蓝色子像素，因此，绿色子像素的馈路电压Vft减小约0.096V，如此可以推知，摇头纹现象可以得到明显的改善。

在其中一个实施例中，本实施例提供一种显示面板，该显示面板包括阵列基板、与阵列基板相对设置的彩膜基板、以及封装在阵列基板与彩膜基板之间的液晶层，阵列基板包括上述至少一实施例中的像素结构，像素单元100沿第一方向DR1和/或第二方向DR2周期性重复，第一方向DR1异于第二方向DR2。
可以理解的是，本实施例提供的显示面板，通过第一数据线、第三数据线分别下接于亮度较高的第二子像素、第五子像素，可以降低第二子像素、第五子像素所受到的耦合电容，进而减小第二子像素、第五子像素所受到的馈路(Feed-through)电压，从而减轻了视觉上的摇头纹现象。
又，像素结构随着扫描线、数据线的对应增加以及像素单元100的数量增多，例如，图4中沿第一方向DR1增加的像素单元100，同理，其也可以沿第二方向DR2增加对应的像素单元，因此，即使像素结构的尺寸存在区别，也可以显著改善摇头纹现象。
其中，上述像素结构可以但不限于为边缘场开关(FFS，Fringe-field switching)型像素结构或者垂直配向(VA，Vertical Alignment)型像素结构，也可以为其他可以适应于本发明构思的其他像素结构，在此不作具体限制。
如图5所示，在第一子像素中，晶体管T1的源极/漏极中的一个与数据线 DL1电性连接，晶体管T1的栅极与扫描线GL1电性连接，晶体管T1的源极/漏极中的另一个通过像素电极11与存储电容Cst1的一端、液晶电容Clc1的一端电性连接，存储电容Cst1的另一端接入公共电压信号Acom，液晶电容Clc1的另一端接入公共电压信号Vcom。当扫描线GL1中的扫描信号控制晶体管T1打开时，像素电极11与扫描线GL2之间产生耦合电容Cpg1。
在第二子像素中，晶体管T2的源极/漏极中的一个与数据线DL1电性连接，晶体管T2的栅极与扫描线GL2电性连接，晶体管T2的源极/漏极中的另一个通过像素电极12与存储电容Cst2的一端、液晶电容Clc2的一端电性连接，存储电容Cst2的另一端接入公共电压信号Acom，液晶电容Clc2的另一端接入公共电压信号Vcom。当扫描线GL2中的扫描信号控制晶体管T2打开时，像素电极12与扫描线GL3之间产生耦合电容Cpg2。
需要进行说明的是，上述各实施例连接至同一子像素的对应扫描线和/或数据线的技术手段可以单独进行改进，也可以同时进行改进。可以理解的是，无论是单独改进还是同时改进均可以取得对应的改善效果，而同时进行改进能够取得更进一步的改善效果。
可以理解的是，对本领域普通技术人员来说，可以根据本申请的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本申请所附的权利要求的保护范围。
