Description

OLED显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种OLED显示装置。
 背景技术
在平板显示技术中，有机电致发光二极管（Organic Light-Emitting Diode，OLED）显示器具有轻薄、主动发光、响应速度快、可视角大、色域宽、亮度高、功耗低及可制备柔性屏等诸多优异特性，引起了科研界和产业界极大的兴趣，逐渐成为继液晶显示器（Liquid crystal displays，LCD）后的第三代显示技术。
OLED显示器件属于自发光型显示设备，通常包括分别用作阳极、与阴极的像素电极、和公共电极、以及设在像素电极与公共电极之间的有机功能层，有机发光层通常又包括层叠的空穴注入层、空穴传输层、发光层、电子传输层、电子注入层，其发光机理为在一定电压驱动下，电子和空穴分别从阴极和阳极注入到电子注入层和空穴注入层，电子和空穴分别经过电子传输层和空穴传输层迁移到发光层，并在发光层中相遇，形成激子并使发光分子激发，后者经过辐射弛豫而发出可见光。
目前摄像功能是手机等终端设备的一个重要使用功能，现有主流技术将具有摄像功能的摄像组件设计在显示装置的外围非显示区，这种方式存在的一大弊端就是显示装置集成度较低，且有效显示面积大大降低。
现如今“全面屏”的设计成为时代的主流，全面屏技术已经越来越多的使用在手机屏幕上，目前各供应商单位都专注于研发屏占比较高的全面屏产品。例如iPhone X手机采用的异形（Notch）屏设计，屏占比可达到81.15%。近期兴起的屏下摄像头设计即O型切割（O-Cut）屏设计，如图1所示，其摄像头设置在显示屏（Panel）100内，通过在显示屏100的有效区（Active Area，AA）110内划分摄像区（Camera Area，CA），并对应CA区切割出“O”形槽500，用于放置并露出摄像头，屏幕下方的外围区130具有IC（集成电路芯片）的固定端，对应于摄像组件区域，显示装置采用开孔式设计，与Notch设计相比，O-Cut设计更趋近于全面屏效果，因此，O-Cut区域远小于Notch区域所占整个Panel的比例，O-Cut设计的全面屏优势更为明显，因此在手机显示屏幕市场占有很大的优势。
传统O-Cut设计方式虽然在一定程度上可以提升显示区面积，但其仍存在一重要缺陷，如图2所示，就是摄像组件800与显示屏100的组装是在两者分别制作完成之后进行，两者相对独立，这样就导致两者集成度问题无法完美解决，且两者由不同厂商生产时易带来尺寸不匹配等问题。
