Description

像素排列结构、金属掩模板、显示面板及显示装置 技术领域
本发明涉及显示技术领域，具体地说，涉及一种像素排列结构、金属掩模板、显示面板及显示装置。
背景技术
随着显示技术的发展，OLED(Organic Light Emitting Diode，有机发光二极管)面板的显示效果的重要性及要求日益提高。目前常用的像素设计是使用红色(R)、绿色(G)、蓝色(B)三种子像素进行组合形成像素单元，显示发光区域由上述像素单元阵列填充组成。
OLED面板的制造过程中通常采用精密金属掩模板(Fine Metal Mask，简称FMM)制备红、绿、蓝发光层，构成红、绿、蓝子像素。然而，在FMM的制作过程中，由于每个开口区域之间都要保留一定的原材料作为桥接部分(Rib)，使得子像素的开口区域受限，影响了像素的开口率，进而对整个显示面板的亮度和使用寿命造成不利影响，使得显示面板的亮度和使用寿命难以提升。因此，如何提升OLED面板中像素的开口率，进而提升OLED面板的亮度和使用寿命，是目前面临的一个问题。

图1公开了现有技术中的一种像素排列结构，也即常见的Real排列结构。参考图1，在该排列结构中，红色子像素11、绿色子像素12和蓝色子像素13均呈倒三角形的矩阵排列形式，该种设计会存在因三色排列为非密排的形式导致像素开口率较低，进而导致总开口发光面积较低，最终影响产品寿命的问题。
图2为现有技术中的另一种像素排列结构，其包含有红色子像素21、绿色子像素22和蓝色子像素23。该类排列结构通常应用于平板电脑等大尺寸显示装置。这类排列结构在蓝色子像素23的单色显示上表现不佳。具体而言，参考图2，该排列结构在显示蓝色子像素23单色的竖线时，会因蓝色子像素23中心在不同行之间的相对位置存在差异而呈现锯齿线(参考图2中的虚线连线)，又因为大尺寸显示屏的像素间距较大，会加剧锯齿显示问题。
如图3所示，本发明一实施例公开了显示面板30。该显示面板30包括显示区域31和非显示区域32，显示区域31通过多个子像素来显示图像。具体到一些实施例中，显示区域31可以为矩形，非显示区域32环绕显示区域31设置，当然，显示区域31和非显示区域32的形状和布置包括但不限于上述的示例。比如，当显示面板30用于佩戴在用户上的可穿戴设备时，显示区域31可以具有像手表一样的圆形形状；当显示基板用于车辆上进行显示时，显示区域31及非显示区域32可采用例如圆形、多边形或其他形状。显示区域31设有发射不同颜色光的多个子像素，比如可以通过红光、绿光和蓝光进行混色形成白光。其中，子像素表征为用于发射光的最小单元(例如为显示面板30的最小可寻址单元)。
其中，本发明实施例提供的显示面板30，可以为有机发光显示面板，子像素至少包括阳极和阴极，以及位于阳极和阴极之间的发光层。像素驱动电路向阳极和阴极之间施加电压，激发载流子迁移，作用于发光层，从而发射出光线。具体地，发光层至少包括空穴传输层、有机材料层及电子 传输层，阳极用于为空穴传输层提供空穴或传输空穴的电极，阴极用于给有机材料层提供电子或传输电子。
为了解决上述像素开口率较低和锯齿显示问题，本发明一实施例公开了一种像素排列结构。本发明的实施例中，像素排列结构包括发射不同颜色光的第一子像素、第二子像素和第三子像素。第一子像素、第二子像素和第三子像素可以分别为蓝色子像素、红色子像素和绿色子像素中的一种，构成一个呈现白光的像素。当然，在其他一些实施例中，第一子像素、第二子像素和第三子像素还可以为红色、绿色和蓝色之外的其他颜色，在此不作限定。
如图4所示，该实施例中，像素排布结构包括多个第一像素单元和多个第二像素单元。上述第一像素单元和上述第二像素单元在行方向上交错排列。参考图5，每一个第一像素单元包括一第一子像素41、一第二子像素42和一第三子像素43。参考图6，每一个第二像素单元包括一第一子像素41、一第二子像素42和两个第三子像素44。其中，第一像素单元和第二像素单元中的第一子像素是同一颜色的子像素，第二子像素也是同一颜色的子像素，第三子像素也是同一颜色的子像素。
其中，上述第一像素单元和第二像素单元中的第一子像素41和第二子像素42各自的开口面积可以相等，开口形状也可以相同。第一像素单元和上述第二像素单元中的第三子像素的开口面积不相等，开口形状可以相同。上述第二像素单元中两个第三子像素的开口面积相等。第一像素单元和第二像素单元阵列填充即形成像素阵列。其中，示例性地，本发明中的行方向和列方向可以是像素阵列的行方向和列方向。
本实施例中，上述像素排布结构包括多个虚拟四边形。多个虚拟四边形以共用边的方式排布。第一像素单元中的第一子像素41、第二子像素42和第三子像素均位于上述虚拟四边形的内部。第二像素单元中的第一子像素41和第二子像素42位于上述虚拟四边形的内部，第二像素单元中的两个第三子像素分别位于虚拟四边形的相对两条虚拟边上。也即，第二像素单元中的两个第三子像素可以沿虚拟四边形行方向上两端排列。第一像素单元中的第三子像素可以在虚拟四边形中行方向上居中排列。
参考图4，本实施例中，上述第一像素单元中第三子像素43的开口 面积大于上述第二像素单元中每一第三子像素44的开口面积。上述第二像素单元中的两个第三子像素之间具有第一间距a。上述第二像素单元中的第一子像素41和第二子像素42之间具有第二间距c1。第一像素单元中的第一子像素41和第二子像素42之间具有第四间距c2。上述第一间距a大于上述第二间距c1。上述第二间距c1等于第四间距c2。这样可以使得第一子像素41和第二子像素42的排布更为紧凑，利于提高第一子像素41和第二子像素42的开口率。其中，对于相邻的第一像素单元和第二像素单元，第一像素单元中的第二子像素42和第二像素单元中的第一子像素41之间具有第五间距c3。在一可选实施例中，第五间距c3、第二间距c1以及第四间距c2三者相等。
其中，上述第一像素单元中单个第三子像素的开口面积可以大于或者等于上述第二像素单元中两个第三子像素的开口面积的和。这样有利于增大像素阵列中第三子像素的开口面积，从而利于提高OLED面板中像素的开口率。在一优选实施例中，上述第一像素单元中单个第三子像素的开口面积等于第二像素单元中两个第三子像素的开口面积的和。
进一步地，作为一优选实施例，上述第一像素单元中第三子像素43沿行方向上的开口宽度是第二像素单元中单个第三子像素44沿行方向上的开口宽度的两倍。同一行中相邻三个第三子像素沿列方向上的开口宽度相等，也即在竖直方向上的宽度相等。也即，上述第二像素单元中的两个第三子像素沿行方向上的开口宽度相等，且沿列方向上的开口宽度相等。上述第一像素单元中第三子像素43和上述第二像素单元中第三子像素44沿列方向上的开口宽度相等。也即，相邻三个蓝色子像素的面积比为1：2：1。这样有利于实现OLED面板中子像素的均一化显示。
对应于金属掩模板同一个开口区域(参考图4中的相应虚线方框)的第三子像素为一组第三子像素，相邻两组第三子像素的间距等于同一第二像素单元中的两个第三子像素之间的第一间距a。第一像素单元中第三子像素43与左侧第二像素单元中相邻的第三子像素44之间的间距为b1。第一像素单元中第三子像素43与右侧第二像素单元中相邻的第三子像素44之间的间距为b2。也即，同一组内的第三子像素具有第三间距，第三间距为b1或b2。上述第三间距小于上述第二间距c1，且小于第四间距c2。 这样可以使得同一组内第三子像素的排布更为紧凑，利于提高同一组内第三子像素的开口率。
本实施例中，位于上述第一像素单元中的第三子像素和相邻且归属于不同的第二像素单元的两个第三子像素对应于金属掩模板的同一个开口区域(参考图4中的相应虚线方框)。也即，同一组的第三子像素共用掩模板的一个开口区域，这样利于进一步提高子像素的开口率。
本实施例中，位于同一列的所有组第三子像素的中心连线平行于像素阵列的列方向，位于同一行的所有第三子像素的中心连线平行于像素阵列的行方向，这样就可以避免当前OLED面板存在的蓝色子像素在列方向上的锯齿显示问题，在蓝色竖线显示效果有更佳的呈现，利于提升OLED显示装置的显示效果。
继续参考图4，本实施例中，相邻两行的第三子像素为重复的排列方式也即为相同的排列方式。也即，相邻两行虚拟四边形中的第三子像素为重复的排列方式。
需要说明的是，在其他实施例中，如图7所示，相邻两行的第三子像素也可以呈交错排列的形式。当相邻两行第三子像素交错排列时，上述第一像素单元中第三子像素43的第一对称线与位于相邻的另一行且同一列的上述第二像素单元中第三子像素44的第二对称线重合。也即，当相邻两行第三子像素交错排列时，相邻两行的两个像素单元中第三子像素的对称线重合。即为第一像素单元中第三子像素43的单点发光中心和第二像素单元中第三子像素44的单点发光中心的中心线重合，也即单点发光中心均位于像素点中心线(参考图7中的虚线连线)上，利于提高第三子像素比如蓝色子像素在列方向上的发光显示效果。相应地，在该实施例中，同一组的第三子像素也可以共用掩模板的一个开口区域(参考图7中的相应虚线方框)，这样利于进一步提高子像素的开口率。
在本发明的另一个实施例中，如图8所示，同一行相邻的第一像素单元和第二像素单元中的第一子像素41关于第三对称线镜像对称设置。同一行相邻的第一像素单元和第二像素单元中的第二子像素42关于第四对称线镜像对称设置。上述第三对称线和上述第四对称线重合。也即，行方向上相邻两个像素单元中的第一子像素41和第二像素单元均为镜像对称 设置。这样可以实现相邻的两个第一子像素41共用掩模板的一个开口区域(参考图8中的相应虚线方框)，相邻的两个第二子像素42共用掩模板的另一个开口区域(参考图8中的相应虚线方框)，同色子像素距离不受金属掩模板在蒸镀过程中的混色等问题影响，也利于进一步提高子像素的开口率。并且，同一组的第三子像素也可以共用掩模板的另一个开口区域(参考图8中的相应虚线方框)。
在该实施例的像素排列结构中，参考图9，两个第二子像素42之间的间距为D2，两个第一子像素41之间的间距为D4，第二像素单元中第一子像素41和第二子像素42之间的间距为D1，第一像素单元中第一子像素41和第二子像素42之间的间距为D3。其中，对于第一子像素41和第二子像素42而言，同一行中同色子像素之间的间距(D2或者D4)小于异色子像素之间的间距(D1或者D3)。使得这样相比于图4和图7对应的实施例，实现了在相同数量的虚拟像素单元内(参考图9中的3个像素单元)，减少了异色子像素间的接触个数即异色子像素间距的占用，可用于设计出开口面积更高的像素排列，可以利于提高子像素的开口面积，进而利于提高像素开口率。另一方面，利于降低金属掩模板的制作难度和蒸镀工艺的难度。其中，优选地，D2和D4可以相等。D1与D3也可以相等。本申请对此不作限定。
在本发明的另一个实施例中，如图10所示，相邻两行的第一像素单元关于第五对称线镜像对称设置。相邻两行的第二像素单元关于第六对称线镜像对称设置。上述第五对称线和上述第六对称线重合。这样可以实现相邻两行的四个第一子像素41可以共用掩模板的一个开口区域(参考图10中的相应虚线方框)，相邻两行的四个第二子像素42可以共用掩模板的另一个开口区域(参考图10中的相应虚线方框)，相邻两行的两组第三子像素(包含6个第三子像素)可以共用掩模板的另一个开口区域(参考图10中的相应虚线方框)。
在一可选实施例中，上述第一间距a小于100μm，由于人眼可分辨的最小距离在100μm，所以这样可以使得即使第二像素单元是两颗第三子像素比如蓝色子像素共同发光承担起该点像素的蓝色发光亮度，使得第二像素单元的发光效果与第一像素单元一致，保证了OLED面板的整体显 示效果，可以呈现均一化显示。
示例性地，在本发明的上述实施例中，上述第一子像素41为红色子像素，第二子像素42为绿色子像素，第三子像素为蓝色子像素。本发明不以此为限。需要说明的是，在本发明的上述实施例中，掩模板的部分开口区域是以虚线方框的形式示例性示出，本发明的附图并未示出全部开口区域。
图11示出了上述显示面板的一种驱动结构。水平的实线为扫描信号线SL，竖直的虚线为数据信号线DL，扫描信号线SL和数据信号线DL呈正交排列。参考图11，在一可选实施例中，上述第二像素单元中的两个第三子像素共用一阳极层，以使得上述两个第三子像素经上述阳极层连接于同一数据信号线，从而实现一条数据信号线驱动共同发光，这样使得二像素单元中的两个第三子像素对称分开排布但共同点亮。这样利于降低驱动电路的布设复杂度，电路结构简单。在其他实施例中，该驱动结构也可以设置为两个蓝色子像素用两条数据信号线分开驱动。或者，可以为两个蓝色子像素由一条数据信号线分开连接驱动。
在OLED面板的制造过程中，需要在两个基板对盒之前在两基板之间加入一定厚度的柱形隔垫物(Photo Spacer，简称PS，也叫做支撑柱)以保持盒厚(Cell Gap)。在本发明的实施例中，支撑柱可摆放于第二像素单元内两个第三子像素沿行方向之间的空间。针对图1对应的技术方案，支撑柱摆放于行方向上每两个异色子像素之间的空间。由于第二像素单元内两个第三子像素之间的间距大于图1中像素阵列的行方向上每两个异色子像素之间的间距，因此相比于图1对应技术方案，支撑柱的可利用空间明显增大，方便支撑柱摆放，从而利于提高支撑柱的抗压能力，降低了支撑柱的压伤风险。
本发明的一些实施例还提供了一种金属掩模板。该金属掩模板用于制作上述任一实施例公开的像素排列结构。其中，像素排列结构的详细结构特征和优势可参照上述实施例的描述，此处不再赘述。该金属掩模板包括多个开口区域，每一个开口区域对应相同颜色的子像素。位于同一开口区域内的一组第三子像素包括上述第一像素单元中的一个第三子像素和归属于不同的第二像素单元的两个第三子像素。
本发明的一些实施例还提供了一种显示面板，该显示面板包括上述任一实施例公开的像素排列结构。其中，像素排列结构的详细结构特征和优势可参照上述实施例的描述，此处不再赘述。本实施例中，
本发明的一些实施例还提供了一种显示装置，该显示装置包括上述实施例公开的显示面板。
本发明实施例所提供的显示装置可以是显示不论运动(例如，视频)还是固定(例如，静止图像)的且不论文字还是的图像的任何装置。更明确地说，预期所述实施例可实施在多种电子装置中或与多种电子装置关联。所述多种电子装置例如(但不限于)移动电话、无线装置、个人数据助理(PDA)、手持式或便携式计算机、GPS接收器/导航器、相机、MP4视频播放器、摄像机、游戏控制台、手表、时钟、计算器、电视监视器、平板显示器、计算机监视器、汽车显示器(例如，里程表显示器等)、导航仪、座舱控制器和/或显示器、相机视图的显示器(例如，车辆中后视相机的显示器)、电子相片、电子广告牌或指示牌、投影仪、建筑结构、包装和美学结构等。
综上，本发明公开的像素排列结构、金属掩模板、显示面板及显示装置至少具有如下优势：
本发明实施例公开的像素排列结构由两种像素单元交错排列形成，两种像素单元中关于第三子像素的数量和结构均不相同，第一像素单元中第三子像素的开口面积大于第二像素单元中每一第三子像素的开口面积，对应两个像素单元中相邻的同组第三子像素可以共用金属掩膜板的同一开口区域，利于提高OLED面板中像素的开口率，从而利于提高OLED面板的亮度和使用寿命。
另一方面，第一像素单元中第三子像素的单点发光中心和第二像素单元中第三子像素的单点发光中心的中心线重合，可以解决当前OLED面板存在的蓝色子像素在列方向上的锯齿显示问题，由此提升了OLED面板的显示效果。
上述金属掩模板、显示面板及显示装置与上述像素排列结构相对于现有技术所具有的优势相同，在此不再赘述。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说 明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
