Abstract

Provided is an organic light-emitting display panel, which comprises a substrate, an organic light-emitting device layer and an encapsulation layer. The organic light-emitting device layer is formed on the substrate; and the encapsulation layer is arranged on the substrate and covers the organic light-emitting device layer. The encapsulation layer comprises an inorganic encapsulation layer and a water-oxygen absorption layer. The inorganic encapsulation layer comprises a first inorganic encapsulation layer and a second inorganic encapsulation layer which are arranged in stack. The water-oxygenabsorber layer is arranged between the first inorganic encapsulation layer and the second inorganic encapsulation layer. Water and oxygen permeated through minor defect channels in the inorganic encapsulation layer is absorbed by the water-oxygen absorption layer when passing through the water-oxygen absorption layer, thereby preventing an organic light-emitting device from being damaged by the water and oxygen and improving the service life of the organic light-emitting display panel.

Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting display panel and a display device. Background technique [0002] Organic light emitting diode (OLED) has many excellent characteristics such as self-illumination, low energy consumption, wide viewing angle, rich color, fast response, and flexible screen preparation, which has aroused great interest in the scientific research community and the industry, and is considered It is a next-generation display technology with great potential. [0003] The organic light-emitting device layer in the organic light-emitting diode is very sensitive to water and oxygen, so when preparing the organic light-emitting display panel, it is necessary to use various means to package the organic light-emitting device. Currently, thin film encapsulation (thin filmencapsulation, TFE) technology has been successfully applied to organic light emitting display panels. [0004] In the prior a...
