Problems solved by technology

The existing packaging structure is relatively simple, and its packaging effect is not good, which will still cause the OLED device to be invaded by water vapor and oxygen, which will cause phenomena such as electrode oxidation, poor chemical reaction of organic materials, or black spots, which will reduce the service life of the OLED device.

Abstract

An OLED panel comprises a light emitting substrate, and a first inorganic layer, an organic layer and a second inorganic layer stacked on the light emitting substrate. The first inorganic layer comprises a plurality of stacked sub-inorganic layers, and the deposition rate of at least one of the sub-inorganic layers is different from that of the other sub-inorganic layers. At least one sub-inorganic layer in the first inorganic layer is deposited at a rate different from that of the other sub-inorganic layers. The invention achieves the purpose of increasing the path of water and oxygen intrusion into the OLED panel, improves the water and oxygen resistance of the OLED panel, thereby improving the packaging effect of the OLED panel and prolonging the service life of the OLED panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as a current-type light-emitting device, is widely used because of its advantages such as self-illumination, rich colors, fast response speed, wide viewing angle, light weight, and flexible display. focus on. [0003] However, OLED devices are very sensitive to moisture and oxygen, and therefore, encapsulation of OLED devices is usually required. The existing packaging structure is relatively simple, and its packaging effect is not good, which will still cause the OLED device to be invaded by water vapor and oxygen, which will cause phenomena such as electrode oxidation, poor chemical reaction of organic materials, or black spots, which will reduce the service life of the OLED device. . Contents of the invention [0004] Embodiments of...
