Abstract

An organic light-emitting display device includes an active array substrate, an encapsulating layer, an organic light-emitting layer, an absorption layer and a sealant. The encapsulating layer is opposite to the active array substrate, and the encapsulating layer has an inner surface facing the active array substrate. The organic light-emitting layer is disposed on the active array substrate. The absorption layer is configured to absorb at least one of moisture and oxygen, and is positioned on the inner surface of the encapsulating layer. The sealant is disposed between the active array substrate and the encapsulating layer, and encircles the organic light-emitting layer and the absorption layer

Description

technical field [0001] The invention relates to an organic light emitting display. Background technique [0002] In recent years, organic light-emitting diode (OLED) technology has flourished. Advantages of OLEDs include high brightness, high contrast, and wide viewing angles. An organic light emitting diode is a type of light emitting diode (LED) that contains an organic electroluminescent layer. The main material of the organic electroluminescent layer is an organic compound that emits light when an electric current passes through the organic compound. The most common problem with OLED devices is the degradation of the organic light-emitting layer. The organic light-emitting layer is prone to react with oxygen and moisture, thereby degrading the performance of the OLED device. Therefore, in the best case, the organic light-emitting layer can be completely sealed within the OLED device. If oxygen and moisture infiltration can be completely prevented, the effective life...
