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
有机发光二极管(Organic Light-Emitting Diode，OLED)显示器，也称为有机电致发光显示器，是一种新兴的平板显示装置，由于其具有自发光、驱动电压低、发光效率高、响应时间短、清晰度与对比度高、近180°视角、使用温度范围宽，可实现柔性显示与大面积全色显示等诸多优点，被业界公认为是最有发展潜力的显示装置。
OLED器件通常包括：基板、设于基板上的阳极、设于阳极上的空穴注入层、设于空穴注入层上的空穴传输层、设于空穴传输层上的发光材料层、设于发光材料层上的电子传输层、设于电子传输层上的电子注入层、及设于电子注入层上的阴极。OLED器件的发光原理为半导体材料和有机发光材料在电场驱动下，通过载流子注入和复合导致发光。具体的，OLED器件通常采用氧化铟锡(ITO)像素电极和金属电极分别作为器件的阳极和阴极，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传输层和空穴传输层，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材料层，并在发光材料层中相遇，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。
如图1所示，现有的OLED显示装置包括：基板100、设于所述基板100上的OLED器件200、设于所述OLED器件200上的封装层300、设于所述封装层300与基板100之间并位于所述OLED器件200外围的封装胶400。为了降低环境光的反射而避免其对OLED显示器画质光学影响，还需要在所述封装层300上设置圆偏光片500，同时为了保护OLED显示装置的表面和圆偏光片500的表面，需要在圆偏光片500上设置保护盖板600。然而封装层300、圆偏光片500和保护盖板600的设置极大的提高了OLED显示装置的厚度，不利于OLED显示装置的轻薄化，同时制造工序复杂。
