Description

显示基板、显示装置及高精度金属掩模板 技术领域
本公开涉及显示技术领域，具体涉及一种显示基板、显示装置及高精度金属掩模板。
背景技术
有机发光二极管显示器(Organic light-emitting diode，OLED)显示器件包括衬底基板、发光层及封装保护层，发光层包括在衬底基板上呈矩阵排列的子像素。各子像素一般通过精细金属掩模板(FMM)将有机发光材料蒸镀在阵列基板相应的子像素位置上。随着技术发展，人们对于显示装置的分辨率的要求也越来越高。
目前限于FMM的制作水平与蒸镀工艺精度，难以通过减小子像素尺寸和减小像素间距的方式增加高分辨率。常用的办法是子像素渲染(Sub-Pixel Rendering，SPR)技术，即利用不同的像素间共享某些位置的子像素，用相对较少的子像素模拟实现更高的分辨率。SPR增加了发光层的开口率，提高了显示器件的开口率和寿命。但是现有的像素排布结构，其虚拟像素亮度中心通常排布不均匀，因而显示一些文字和特定图形时，不可避免带来显示的颗粒感和扭曲感。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
请参考图1，图1为相关技术中的像素排布结构示意图，图1中蓝色子像素(B)和红色子像素(R)均为正方形，该种结构下，在第i-1行，第j列虚拟像素与第j+1列的虚拟像素的亮度中心(图中黑点)的间距l1，大于第j列虚拟像素与第j-1列的虚拟像素的亮度中心的间距l2，在第i行，第j列虚拟像素与第j+1列的虚拟像素的亮度中心(图中黑点)的间距，小于第j列虚拟像素与第j-1列的虚拟像素的亮度中心的间距，从而导致在显示竖线或者竖线为主的图像 时，人眼会有可察觉到的扭曲感和颗粒感。
为解决上述问题，请参考图2，本公开实施例提供一种显示基板，包括：第一子像素R，第二子像素G和第三子像素B；
在第一方向上，所述第一子像素R和所述第三子像素B交替排列形成第一子像素排，所述第二子像素G形成第二子像素排；
在第二方向上，所述第一子像素排和所述第二子像素排交替排列，所述第一方向和所述第二方向垂直或大致垂直；
分布在相邻两行两列的两个第一子像素R和两个第三子像素B形成2*2矩阵，所述2*2矩阵中，所述两个第一子像素R位于不同行不同列，所述两个第三子像素B位于不同行不同列，所述两个第一子像素R和所述两个第三子像素B的中心连线形成一个虚拟四边形，所述第二子像素G位于所述虚拟四边形内；
同一所述虚拟四边形对应的所述两个第一子像素R的中心、所述两个第三子像素B的中心，分别到所述第二子像素G的中心的间距中，至少有两个不同；
所述第三子像素B包括沿第一斜线方向的对称轴以及沿第二斜线方向的对称轴，所述第三子像素B在第一斜线方向上的宽度与在第二斜线方向上的宽度不同(其中一个为W1，一个为H1)，其中，所述第二斜线方向与所述第一斜线方向垂直或大致垂直，且所述第二斜线方向与所述第一斜线方向，与第一方向和第二方向均相交。
从图2中可以看出，位于同一排的相邻的第一子像素R和第三子像素B，与下一排的一个第二子像素G，组成一个虚拟像素(图中的三角形)，且，同一行相邻的虚拟像素共享一个第一子像素R或一个第三子像素B。
另外，从图2中也可以看出，本公开实施例中，位于同一行的相邻虚拟像素的亮度中心之间的间距的差异，要小于相关技术中同一行的相邻虚拟像素的亮度中心之间的间距的差异，即本公开实施例中虚拟像素的亮度中心排布更均匀。
本公开实施例中，一方面，通过共享子像素，可以实现更高的分辨率，另一方面，通过设置第三子像素在不同斜线方向上的宽度不同，使得虚拟四边形中两个第一子像素的中心、两个第三子像素的中心，分别到第二子像素的中心的间距中，至少有两个不同，从而实现虚拟像素的亮度中心排布更均匀，避免显示的颗粒感和扭曲感，提高显示效果。再一方面，也无需移动子像素的位置，就可以使得虚拟像素的亮度中心产生位移，实现成本较低。
本公开实施例中，可选的，同一所述虚拟四边形对应的所述两个第一子像素的中心、所述两个第三子像素的中心，分别到所述第二子像素的中心的间距中，至少有两个相同。

本公开实施例中，可选的，同一所述虚拟四边形对应的所述两个第一子像素的中心、所述两个第三子像素的中心，分别到所述第二子像素的中心的间距中，任意两个的比值范围为0.7-1.3。

(7)、在形成前述图案的衬底基板上，依次形成有机功能层以及第二电极。在一些示例中，第二电极为透明阴极。发光元件可以通过透明阴极从远离衬底基板10一侧出光，实现顶发射。在一些示例中，发光元件的有机功能层包括：空穴注入层、空穴传输层、发光层以及电子传输层。
在一些示例性实施方式中，在形成前述图案的衬底基板10上采用开放式掩膜版(Open Mask)依次蒸镀形成空穴注入层241和空穴传输层242，然后采用FMM依次蒸镀形成蓝色发光层236、绿色发光层216和红色发光层226，然后采用开放式掩膜版依次蒸镀形成电子传输层243、阴极244以及光耦合层245。空穴注入层241、空穴传输层242、电子传输层243以及阴极244均为多个子像素的共通层。在一些示例中，有机功能层还可以包括：位于空穴传输层和发光层之间的微腔调节层。例如，可以在形成空穴传输层之后，采用FMM依次蒸镀形成蓝色微腔调节层、蓝色发光层、绿色微腔调节层、绿色发光层、红色微腔调节层、红色发光层。
在一些示例性实施方式中，有机功能层形成在子像素区域内，实现有机功能层与阳极连接。阴极形成在像素定义层上，并与有机功能层连接。
在一些示例性实施方式中，阴极可以采用镁(Mg)、银(Ag)、铝(Al)中的任意一种或更多种，或采用上述金属中任意一种或多种制成的合金，或者采用透明导电材料，例如，氧化铟锡(ITO)，或者，金属与透明导电材料的多层复合结构。
在一些示例性实施方式中，可以在阴极244远离衬底基板10的一侧形成光耦合层，光耦合层可以为多个子像素的共通层。光耦合层可以与透明阴极配合，起到增加光输出的作用。例如，光耦合层的材料可以采用半导体材料。然而，本实施例对此并不限定。
(8)、在形成前述图案的衬底基板上，形成封装层。
在一些示例性实施方式中，在形成前述图案的衬底基板10上形成封装层，封装层可以包括叠设的第一封装层41、第二封装层42和第三封装层43。第一封装层41采用无机材料，在显示区域覆盖阴极244。第二封装层42采用有机材料。第三封装层43采用无机材料，覆盖第一封装层41和第二封装层42。然而，本实施例对此并不限定。在一些示例中，封装层可以采用无机/有机/无机/有机/无机的五层结构。
以上所述是本公开的部分实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
