Description

一种有机发光模组及应用其的显示装置 技术领域
本发明涉及有机电致发光领域，具体涉及一种有机发光模组及应用其的显示装置。
背景技术
有机显示装置(英文全称为Organic Light-Emitting Device，简称为OLED)是主动显示装置。相比现有平板显示技术中薄膜晶体管液晶显示器(英文全称Liquid Crystal Display，简称LCD)、等离子体显示面板(英文全称Plasma Display Panel,简称PDP),OLED具有高对比度、广视角、低功耗、体积更薄等优点，有望成为下一代主流平板显示技术，是目前平板显示技术中受到关注最多的技术之一。
有机显示装置包括有机发光模组，有机发光模组进一步包括叠置的驱动背板、有机发光单元层以及封装盖板。由于有机发光单元对空气中的水氧极为敏感，极少量的水氧都可能会造成有机功能材料的劣化，从而影响装置的使用寿命。因此，现有技术中，大多采用玻璃基板对有机发光模组进行封装。然而，由于玻璃基板存在一定的厚度，有机发光模组侧壁易发生漏光和光线折射的问题，严重影响其显示效果。
发明内容
为此，本发明所要解决的是现有有机发光模组侧壁易发生漏光和光线折射的问题。
为解决上述技术问题，本发明采用的技术方案如下：
本发明提供一种有机发光模组，包括第一玻璃基板，设置在所述第一玻 璃基板上并形成闭合图形的封装层，以及设置在所述封装层上的第二玻璃基板；所述第一玻璃基板和所述第二玻璃基板通过所述封装层形成中空腔体，所述有机发光模组还包括夹设在所述腔体内的有机发光单元；所述第一玻璃基板和/或所述第二玻璃基板的侧壁上设置有遮光层。
可选地，所述遮光层厚度为0～50μm。

第一玻璃基板1和第二玻璃基板4的侧壁上设置有遮光层5，遮光层5选自但不限于黑色油墨层，通过喷涂或者涂刷工艺制备，工艺非常简单。
遮光层5的设置能够实现有机发光模组在工作时不发生漏光的现象，以及吸收或反射外界环境光线，避免环境光线影响有机发光显示单元3发光。使得显示效果更亮丽，而且，遮光层通过喷和/或涂布工艺制备，厚度小，不影响应用其的显示装置的组装。

如图1所示，应当理解的是，本发明中所述的第一玻璃基板1厚度D1、所述第二玻璃基板4的厚度D2、所述封装层5的厚度D4均是沿垂直于所述玻璃基板1、4所在平面方向上的厚度，即Y方向的厚度；本发明中所述的遮光层5厚度D3的厚度为沿平行于所述玻璃基板1、4所在平面方向上的厚度，即X方向的厚度。
本实施例还提供一种显示装置，包括所述有机发光模组，还包括用于驱动有机发光模组的驱动模组。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明的保护范围之中。
