Description

有机发光二极管像素排列结构
【技术领域】
本发明涉及半导体显示器件技术领域，特别是涉及一种有机发光二极管像素排列结构。
【背景技术】
有机发光二极管（OLED，Organic Light Emitting Diode）由于具有自主发光、可视角大、色域宽、反应时间短、对比度高的显示特性，且具有轻薄、柔性等优点，已成为继液晶显示器的第三代显示技术。
传统技术中，有机发光二极管像素排列结构通常由多个像素点组成，每个像素点包含红色（R）子像素、绿色（G）子像素和蓝色（B）子像素，R、G、B子像素依次循环排列，组成矩阵。R、G、B子像素为方形，方形的长边与短边与水平线相互垂直或平行（这里所说的水平线直观上与纸面的横向相平行，在蒸镀工艺中线性蒸发源按水平线排列，在蒸镀时，扫描方向与线性蒸发源相垂直）。
传统的有机发光二极管像素结构受阴影（shadow）效应的影响比较大，其具体为，在蒸镀时，由于线性蒸发源呈水平线排列，扫描方向与水平线垂直，并且蒸发源具有蒸镀角，掩膜板与玻璃基板还存在一定间隙，这样，通过具有开口的掩膜板蒸镀得到的子像素，往往相对于掩膜板上的开口具有阴影，阴影越大，掩膜板开口之间的距离越大，这样开口之间的金属面积就会增大，从而降低了开口率（像素发光面积与像素总面积之比），增大掩膜板上开口之间距离的同时也会降低像素分辨率（PPI，Pixels Per Inch）。
【发明内容】
基于此，有必要提供一种能够降低阴影效应影响的有机发光二极管像素排列结构。
一种有机发光二极管像素排列结构，包括：多个第一子像素，相邻两个第一子像素排列成第一子像素团，多个第二子像素，相邻两个第二子像素排列成第二子像素团，多个第三子像素，相邻两个第三子像素排列成第三子像素团，所述多个第一子像素、所述多个第二子像素及所述多个第三子像素组成多个矩阵，每个所述矩阵内均包括至少一个所述第一子像素、所述第二子像素及所述第三子像素，并且所述第一子像素团、所述第二子像素团、所述第三子像素团与蒸镀工艺中掩膜板的方形开口对应，所述方形开口的一条边与线性蒸发源的排列方向之间具有倾斜角，所述倾斜角为锐角或者钝角。
上述有机发光二极管像素排列结构，由于此倾斜角的存在，在蒸镀时，能够减少阴影效应的影响，利于制造高开口率和高分辨率的有机发光显示器。

【具体实施方式】
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施方式。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本发明的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1，其为一个实施例中的有机发光二极管像素排列结构的局部示意图。
有机发光二极管像素排列结构包括：多个第一子像素、多个第二子像素和多个第三子像素。相邻两个第一子像素排列成第一子像素团，相邻两个第二子像素排列成第二子像素团，相邻两个第三子像素排列成第三子像素团（图中示意性地绘出其中一个子像素团）。其中，多个第一子像素、多个第二子像素及多个第三子像素组成多个矩阵，每个矩阵内均包括至少一个第一子像素、一个第二子像素及一个第三子像素；并且，第一子像素团、第二子像素团、第三子像素团与蒸镀工艺中掩膜板的方形开口对应，方形开口的一条边与线性蒸发源的排列方向之间具有倾斜角，也可以理解为，其中一个子像素团内的子像素的排列方向与线性蒸发源的排列方向之间形成倾斜角A，且该倾斜角为锐角或者钝角，即倾斜角不为0°、90°或180°。本实施例中，蒸镀工艺中的线性蒸发源沿水平线方向排列。
如图2及图3所示，其分别为一种有机发光二极管像素排列结构产生的阴影效应的示意图，以及图1所示实施例中的有机发光二极管像素排列结构如何减少阴影效应的原理示意图。
图2中，实线为掩膜板上对应于一个子像素的开口，虚线为产生的阴影的大小，设竖直阴影的宽度为L1水平阴影的宽度为L2。
图3中，方形开口的一条边与水平线之间的倾斜角为A，即方形开口的一条边与线性蒸发源的排列方向之间的倾斜角为A，这里仅以0<A<90°为例来说明（对于90°<A<180°推理类似），由于线性蒸发源的排列方向定义为水平线方向（纸面上横向方向），蒸镀工艺的扫描方向与水平线垂直，因此在水平方向和竖直方向产生的阴影大小可以认为不会发生变化，仍然为L1和L2，故图3中的子像素实际阴影大小为：L3=L1 sinA，L4=L2 sinA，均会变小，利于制作高开口率和高分辨率的显示器。
