Description

像素结构及包含所述像素结构的显示面板 技术领域
本公开涉及显示技术领域，特别涉及一种像素结构及包含该像素结构的显示面板。
背景技术
OLED(Organic Light-Emitting Diode，有机发光二极管)是主动发光器件。与传统的LCD(Liquid Crystal Display，液晶显示)显示方式相比，OLED显示技术无需背光源，具有自发光的特性。OLED采用较薄的有机材料膜层和玻璃基板，当有电流通过时，有机材料膜层就会发光。因此OLED显示面板能够显著节省电能，可以做得更轻更薄，比LCD显示面板耐受更宽范围的温度变化，而且可视角度更大。OLED显示面板有望成为继LCD之后的下一代平板显示技术，是目前平板显示技术中受到关注最多的技术之一。
OLED屏体的彩色化方法有许多种，现在较为成熟并已经成功量产的OLED彩色化技术主要是OLED蒸镀技术，其采用传统的RGB Stripe(RGB条状)排列方式进行蒸镀。其中画面效果最好的是side-by-side(并置)的方式。side-by-side方式是在一个像素(Pixel)范围内有红、绿、蓝(R、G、B)三个子像素(sub-pixel)，每个子像素均呈四边形，且各自具有独立的有机发光元器件，它是利用蒸镀成膜技术透过高精细金属掩膜版(Fine Metal Mask，FMM)在array(阵列)基板上相应的像素位置形成有机发光元器件，所述高精细金属掩膜版通常简称为金属掩膜版或蒸镀掩膜版。制作高PPI(Pixel Per Inch，每英寸所拥有的像素数目)的OLED显示面板的技术重点在于精细及机械稳定性好的FMM以及像素(子像素)的排布方式。
图1为现有技术中一种OLED显示面板的像素排布示意图。如图1所示，该OLED显示面板采用像素并置的方式，每个像素单元Pixel包括R子像素区域101、G子像素区域103以及B子像素区域105，其中，R子像素区域101包括R发光区102以及R非发光区(未标号)，G子像素区域103包括G发光区104以及G非发光区(未标号)，B子像素区域105包括B发光区106 以及B非发光区(未标号)。图1中所示R、G、B子像素区域和发光区面积分别相等，并且R、G、B子像素呈直线排列。具体而言，在每个子像素区域的发光区中，包括阴极、阳极和电致发光层(亦称为有机发射层)，其中，电致发光层位于阴极和阳极之间，用于产生预定颜色光线以实现显示。在制备现有技术中显示面板时，通常需要利用三次蒸镀工艺以分别在对应颜色像素区域的发光区中形成对应颜色(红色、绿色或蓝色)的电致发光层。
图1所示的OLED显示面板通常采用图2所示FMM进行蒸镀，该种FMM包括遮挡区107以及若干个蒸镀开口108，同一列相邻的两个蒸镀开口108之间的遮挡区称之为连接桥(bridge)。为了避免蒸镀时对子像素产生遮蔽效应，子像素与bridge间必须保持足够的距离，这就导致子像素上下的长度缩小，而影响了每一个子像素的开口率。传统的RGB并置像素排列方式，最高只能达到200～300PPI，难以实现高分辨率的显示效果。随着用户对OLED显示面板分辨率的需求越来越高，这种RGB像素并置的方式已不能满足产品高PPI的设计要求。
图3为现有技术中另一种OLED显示面板的像素排布示意图。如图3所示，每个像素单元仅有G子像素是独用的，R和B子像素均被与相邻的像素单元共用，比如，像素单元201和像素单元202共用R子像素。这种方式可以提高显示屏的PPI，然而，这种排布方式中R和B子像素被相邻的像素单元共用，整个显示效果可能存在畸变，不是真正意义上的全彩显示。
发明内容
发明人经过研究发现，传统的RGB像素排列方式已不能同时满足产品的开口率和显示效果的要求。基于此，本公开提供一种像素结构及包含所述像素结构的显示面板，以解决现有技术中存在的问题。
为解决上述技术问题，本公开提供一种像素结构，包括阵列排布的多个像素单元，所述像素单元分别沿第一方向和与所述第一方向垂直的第二方向排布，每个像素单元均包括颜色彼此不同的第一子像素、第二子像素和第三子像素，在所述第二方向上，所述第三子像素之间的间距不等于所述第一子 像素之间的间距，并且不等于所述第二子像素之间的间距。
可选的，在所述第二方向上，所述第三子像素之间的间距大于所述第一子像素之间的间距，并且大于所述第二子像素之间的间距。
可选的，在所述第二方向上，所述第三子像素之间的间距小于所述第一子像素之间的间距，并且小于所述第二子像素之间的间距。
可选地，所述第一子像素之间的间距等于所述第二子像素之间的间距。
可选地，在每个像素单元中，在所述第二方向上，所述第一子像素和所述第二子像素的总尺寸大于所述第三子像素的尺寸。
可选地，在每个像素单元中，该像素单元在所述第一方向上的尺寸大于该像素单元在所述第二方向上的尺寸。
在每个像素单元中，该像素单元在所述第一方向上的尺寸与该像素单元在所述第二方向上的尺寸的比为3：2、2:1、4:3或5:4。
可选地，在所述第一方向上多个相邻的像素单元内，所述第三子像素在所述第一方向上的尺寸递增或递减，并且以所述多个相邻的像素单元作为重复单元组沿所述第一方向和所述第二方向重复排列，或者
在所述第二方向上多个相邻的像素单元内，所述第三子像素在所述第二方向上的尺寸递增或递减，并且以所述多个相邻的像素单元作为重复单元组沿所述第一方向和所述第二方向重复排列。
可选地，所述多个相邻的像素单元的数量为三个以上。
在每个像素单元中，所述第一子像素和所述第二子像素在所述第二方向上共线地排布，所述第三子像素与所述第一子像素和所述第二子像素在所述第一方向上并排地排布。
可选地，每个像素单元沿所述第一方向翻转180度后的排布结构与在所述第二方向上和该像素单元相邻的像素单元的排布结构相同，或者
每个像素单元沿所述第二方向翻转180度后的排布结构与在所述第一方向上和该像素单元相邻的像素单元的排布结构相同。
可选地，所述第一子像素、所述第二子像素和所述第三子像素为红色子像素、绿色子像素和蓝色子像素中的一种。
可选地，所述第一方向为行方向，所述第二方向为列方向，或者
所述第一方向为列方向，所述第二方向为行方向。
根据本公开的另一面，还提供一种显示面板，包括如上所述的像素结构。
1、本公开提供一种显示面板的像素结构，每个像素单元分别沿行方向或列方向相邻设置，每个像素单元由三个不同颜色的子像素组成，可以实现真正意义上的全色显示；
2、每个像素单元包括第一子像素、第二子像素和第三子像素，第一子像素和第二子像素排布在一列，第三子像素排布在另一列，第一子像素和第二子像素沿列方向的总尺寸大于第三子像素沿列方向的尺寸，同一行中像素单元的排布结构相同，并且，每个像素单元翻转180度后的排布结构与同一列中相邻的像素单元的排布结构相同，像素单元可以更紧凑的排列，减少了像素间距，提高了PPI；同时，当所述第一子像素和第二子像素排布在一列时，同一列上相邻两个像素单元的第三子像素是相互错开排布的，可降低蒸镀掩膜版制作工艺和蒸镀工艺的难度；
3、不同列的像素单元错位排布，可以较好地改善屏体显示区域上下侧绿亮线、红亮线等问题；其中一个子像素在行方向或列方向的尺寸不等于其余两个子像素在行方向或列方向的尺寸，优选蓝色子像素的的尺寸大于红色子像素与绿色子像素的尺寸，可根本改变因现有局部/单点亮度过亮或寿命衰减过快的缺陷，可更好地从全屏的角度来平衡蓝色子像素的寿命，减缓因局部衰减过快造成的偏色问题。

具体实施方式
本公开中所述的行和列均以及左和右是为说明本公开而以图中所示为参考标准的，并非指实际产品中的行和列以及左和右。如；本公开中的“行方向”可以是X方向，“列方向”可以是Y方向(第二方向)。然而，本公开的“行”和“列”的含义并不仅仅限定于常规意义上的“行”和“列”，还可以是常规意义上的“行”和“列”同时顺时针90度或逆时针旋转90度而形成的“行”和“列”。在以下实施例中，用相同或相似的附图标记表示相同或相似的部分。
实施例一
图4为本公开实施例一中显示面板的像素排布示意图。其中，X方向称之为行方向(横向)，Y方向称之为列方向(纵向)。为简便，附图中只表示出了OLED显示面板的一部分，实际产品中像素数量不限于此，像素单元的数量可依据实际显示需要作相应的变化。
如图4所示，显示面板的像素结构包括阵列排布的多个像素单元，每个像素单元均包括第一子像素301、第二子像素303和第三子像素305。在同一个像素单元内，所述第一子像素301和第二子像素303排布在一列，所述第三子像素305排布在另一列，第一子像素301和第二子像素303沿列方向的总尺寸L1(即第一子像素301和第二子像素303沿列方向的尺寸之和)大于 第三子像素305沿列方向的尺寸L2，同一行中所有像素单元的排布结构相同，并且，每个像素单元沿行方向翻转(自身左右翻转)后的排布结构与同一列中相邻的像素单元的排布结构相同。如此一来，像素单元可以更紧凑的排列，减少了像素间距，提高了PPI，并且，每个像素单元是由RGB三色组成，可以实现真正意义上的全色显示。
进一步的，由于本公开中像素单元的排布方式更为紧凑，可以使得像素单元沿行方向的总尺寸更大，进而使得像素单元沿行方向的总尺寸(即像素单元在行方向的最大尺寸)大于像素单元沿列方向的最大尺寸(这里是指第一子像素301和第二子像素303沿列方向的尺寸之和)，即，使得L0大于L1，比如是L0：L1＝3:2，这样，与传统的正方形像素单元(行方向尺寸与列方向尺寸之比为1:1)相比，本实施例中的2个像素单元可以实现传统的3个像素单元的显示效果。当然，本公开并不限制L0与L1的具体比例关系，像素单元沿行方向的总尺寸L0与像素单元沿列方向的最大尺寸L1之间的比值也可以是2:1、4:3、5:4等。
在此，第一行第一列的像素单元记为像素单元(1，1)，第一行第二列的像素单元记为像素单元(1，2)，第二行第一列的像素单元记为像素单元(2，1)，第二行第二列的像素单元记为像素单元(2，2)，其它类推。如图4所示，第一行第三列的像素单元(1，3)向右翻转180度后的排布结构与同一列中相邻行的像素单元即第二行第三列的像素单元(2，3)的排布结构相同。可见，同一列上相邻两个像素单元，比如，像素单元(1，3)和像素单元(2，3)的第三子像素相互错开排布，即，在列方向上像素单元(1，3)和像素单元(2，3)的第三子像素并未排布在一条直线上，因而，用以形成第三子像素的蒸镀掩膜版(FMM)上的蒸镀开口也是错开排布的，可降低蒸镀掩膜版制作工艺和蒸镀工艺的难度。
本实施例中，第一子像素301、第二子像素303和第三子像素305的发光区可以呈“品”字形、倒“品”字形、向左旋转90度的“品”字形或向右旋转90度的“品”字形排布，也可以是大致呈“品”字形、倒“品”字形、向左旋转90度的“品”字形或向右旋转90度的“品”字形。图4所示的排布结构中，奇数行的像素单 元中，第一子像素301的发光区302、第二子像素303的发光区304和第三子像素305的发光区306呈向右旋转90度的“品”字形(大致上的品字形)排布，即，第一子像素301和第二子像素303排布在左侧，第三子像素305排布在右侧；偶数行的像素单元中，第一子像素301的发光区302、第二子像素303的发光区304和第三子像素305的发光区306呈向左旋转90度的“品”字形(大致上的品字形)排布，即，第三子像素305排布在左侧，第一子像素301和第二子像素303排布在右侧。进一步的，同一行中所有像素单元的第一子像素301排布在一条直线上，同一行中所有像素单元的第二子像素亦是排布在一条直线上。
在本实施例中，在同一列的像素单元内，相邻的第一子像素301在列方向上的间距等于相邻的第二子像素303在列方向上的间距，且相邻的第一子像素301在列方向上的间距，以及相邻的第二子像素303在列方向上的间距均大于相邻的第三子像素305在列方向上的间距。具体的，请参照图5所示，在同一列的像素单元内，相邻的第一子像素301在列方向上的间距y1等于相邻的第二子像素303在列方向上的间距y2，并且相邻的第一子像素301在列方向上的间距y1与相邻的第二子像素303在列方向上的间距y2均大于相邻的第三子像素305在列方向上的间距y3。
优选的，在同一个像素单元内，所述第三子像素305在列方向上的下表面高于或等于所述第二子像素303在列方向上的下表面，即所述第三子像素305在列方向上的下表面所在的平面(如图5中的A1)要高于或者等于(即不低于)所述第二子像素303在列方向上的下表面所在的平面(如图5中的A2)，防止第三子像素305与第一子像素301、第二子像素303相差太远，对显示造成影响。优选的，在同一个像素单元内，第三子像素305沿行方向延伸的中心线与第一子像素301和第二子像素303之间的边界线的距离小于等于10μm。
本实施例中，第一子像素301为绿色(G)子像素，第二子像素303为红色(R)子像素，第三子像素305为蓝色(B)子像素；因此，第一子像素301包括G发光区302以及G非发光区(图中未标号)，并且包括用于发射绿光 的有机发射层；第二子像素303包括R发光区304以及R非发光区(图中未标号)，并且包括用于发射红光的有机发射层；第三子像素305包括B发光区306以及B非发光区(图中未标号)，并且包括用于发射蓝光的有机发射层。由于B子像素的发光效率通常是最低的，相应地所需要的发光面积就要更大，故而，第三子像素305的发光面积大于第一子像素301和第二子像素303的发光面积。在其他实施例中，所述第一子像素301也可以是红色子像素，所述第二子像素303也可以是绿色子像素，所述第一子像素与第二子像素可以互换。
优选方案中，第一子像素301和第二子像素303的形状和面积均相等，即呈镜像对称分布。需要说明的是，由于同一个像素单元内的第一子像素301和第二子像素303共用一条边，该共用的边即为第一子像素301和第二子像素302之间的边界线，但应理解，此处的“边界”或“边界线”并不限定为实体的“边界”或“边界线”，而可以是指两个像素子像素之间虚拟的“边界”或“边界线”。
本实施例中，第一子像素301和第二子像素303的形状均为长方形，第三子像素305的形状为正方形，且所述第一子像素301和第二子像素303沿其短边方向排列，其中，第三子像素305的发光区306的边长(高度)为第一子像素301的发光区302的短边长度和第二子像素303的发光区304的短边长度(高度)的2倍。但应理解的是，第一子像素301、第二子像素303以及第三子像素303的形状并不局限于矩形，还可以是矩形之外的其它四边形，或者是三角形、五边形、六边形、八边形等多边形中的一种或其任意组合。同时，第一子像素301和第二子像素303的面积也可以不相等，并且，第三子像素305的发光面积也并不限制为第一子像素301或第二子像素303的发光面积的2倍，可以根据配色要求来相应调整各个子像素的形状和/或面积。
实施例二
图6为本公开实施例二所示的显示面板的像素排布示意图。本实施例与实施例一的区别之处在于，在同一列的像素单元内，相邻的第一子像素301在列方向上的间距等于相邻的第二子像素303在列方向上的间距，且相邻的 第一子像素301在列方向上的间距，以及相邻的第二子像素303在列方向上的间距小于相邻的第三子像素305在列方向上的间距。
具体的，请参照图7所示，在同一列的像素单元内，相邻的第一子像素301在列方向上的间距y1等于相邻的第二子像素303在列方向上的间距y2，并且相邻的第一子像素301在列方向上的间距y1与相邻的第二子像素303在列方向上的间距y2均小于相邻的第三子像素305在列方向上的间距y3。优选的，同一个像素单元内，所述第三子像素305在列方向上的上表面低于或等于所述第一子像素301在列方向上的上表面，即所述第三子像素305在列方向上的上表面所在的平面(如图7中的A1)要低于或者等于(即不高于)所述第一子像素301在列方向上的上表面所在的平面(如图7中的A2)，防止第三子像素305与第一子像素301、第二子像素303相差太远，对显示造成影响。优选的，在同一个像素单元内，第三子像素305沿行方向延伸的中心线与第一子像素301和第二子像素303之间的边界线的距离小于等于10μm。
实施例三
图8为本公开实施例三所示的显示面板的像素排布示意图。本实施例与实施例一的区别之处有两点。
第一点：在本实施例中，每个像素单元中，第三子像素305沿行方向延伸的中心线与第一子像素301和第二子像素303之间的边界线重合，这样，可以进一步减少像素间距(pitch)，提高显示屏的PPI，并使得RGB子像素分布均匀，具有较佳的显示效果。具体可参考图8，第三子像素305沿行方向延伸的中心线306’(该中心线306’将第三子像素305均分为两份且该中心线306’沿行方向延伸)与第一子像素301和第二子像素303之间的边界线重合。
第二点：在本实施例中，在同一列的多个相邻的像素单元内，所述第三子像素在列方向上的尺寸递增，且尺寸呈递增的第三子像素所在的该多个相邻的像素单元作为一个重复单元组在列方向上重复排列。优选的，在同一列的三个相邻的像素单元内，三个所述第三子像素在列方向上的尺寸递增，具体的，请参照图9所示，三个所述第三子像素305在列方向上的尺寸H1、H2、H3递增，并且以这三个相邻的像素单元作为一个重复单元组在列方向上重复 排列，即在列方向上，所有的第三子像素305三个一组，其尺寸按照H1、H2、H3、H1、H2、H3……变化。优选的，三个所述第三子像素305在列方向上的尺寸比H1：H2：H3＝3:4:5。当然，也可以是同一列的四个或更多个相邻的像素单元内的第三子像素在列方向上的尺寸递增，但是需要满足：在同一个像素单元内，所述第一子像素301和第二子像素303沿列方向的总尺寸大于所述第三子像素305沿列方向的尺寸。
蓝色子像素的尺寸大于红色子像素的尺寸，并大于绿色子像素的尺寸，可根本改变因现有局部/单点亮度过亮或寿命衰减过快的缺陷，可更好地从全屏的角度来平衡蓝色子像素的寿命，减缓因局部衰减过快造成的偏色问题。
实施例四
图10为本公开实施例四所示的显示面板的像素排布示意图。本实施例与实施例三的区别之处在于，在同一列的多个相邻像素单元内，所述第三子像素在列方向上的尺寸递减，且尺寸呈递减的第三子像素所在的该多个相邻的像素单元作为一个重复单元组在列方向上重复排列。优选的，在同一列的三个相邻的像素单元内，三个所述第三子像素在列方向上的尺寸递减，具体的，请参照图11所示，三个所述第三子像素305在列方向上的尺寸H1、H2、H3递减，并且以这三个相邻的像素单元作为一个重复单元组在列方向上重复排列，即在列方向上，所有的第三子像素305三个一组，其尺寸按照H1、H2、H3、H1、H2、H3……变化。优选的，三个所述第三子像素305在列方向上的尺寸比H1：H2：H3＝5:4:3。当然，也可以是同一列的四个或更多个相邻的像素单元内的第三子像素在列方向上的尺寸递减，但是需要满足：在同一个像素单元内，所述第一子像素301和第二子像素303沿列方向的总尺寸大于所述第三子像素305沿列方向的尺寸。
在以上的实施例中，在奇数行的像素单元中，第一子像素301的发光区302、第二子像素303的发光区304和第三子像素305的发光区306呈向右旋转90度的“品”字形排布，即，第一子像素301和第二子像素303排布在左侧，第三子像素305排布在右侧；偶数行的像素单元中，第一子像素301的发光区302、第二子像素303的发光区304和第三子像素305的发光区306呈向左 旋转90度的“品”字形排布，即，第三子像素305排布在左侧，第一子像素301和第二子像素303排布在右侧。
在其他的实施例中，所述像素单元的排布方式也可以为：在奇数行的像素单元中，第一子像素301的发光区302、第二子像素303的发光区304和第三子像素305的发光区306呈向左旋转90度的“品”字形排布，即，第三子像素305排布在左侧，第一子像素301和第二子像素303排布在右侧；偶数行的像素单元中，第一子像素301的发光区302、第二子像素303的发光区304和第三子像素305的发光区306呈向右旋转90度的“品”字形排布，即，第一子像素301和第二子像素303排布在左侧，第三子像素305排布在右侧。
实施例五
图12为本公开实施例五中显示面板的像素排布示意图。本实施例与上述实施例的区别之处在于，在本实施例中，像素单元包含的三个子像素沿行方向或列方向排布，且不同行或不同列的像素单元错位排布。
请参见图12所示，所述像素单元包括第一子像素301、第二子像素303与第三子像素305；所述第一子像素301、第二子像素303和第三子像素305排布在一列，同一列中像素单元的排布结构相同，并且，每个像素单元沿列方向翻转180度后的排布结构与在行方向上和该像素单元相邻的像素单元的排布结构相同，例如在第一行第一列的像素单元(1,1)包括沿列方向排布的第一子像素301、第二子像素303与第三子像素305，该像素单元(1,1)沿列方向翻转180度后的排布结构为第三子像素305、第二子像素303与第一子像素301，与第一行第二列的像素单元(1,2)的排布方式相同。
同一列中像素单元的排布结构相同，并且不同列的像素单元错位排布，即相邻两列像素单元的两端并不对齐，可以较好地改善屏体显示区域上下侧绿亮线、红亮线等问题。
实施例六
本实施例提供一种显示面板，可以采用实施例一至五中任一所述的像素结构。
