Abstract

The invention provides an OLED panel and a packaging method. The OLED panel comprises a light-emitting substrate, and at least one group of packaging films arranged on the light-emitting substrate, wherein each group of packaging films comprise a first inorganic layer arranged on the light-emitting substrate; each first inorganic layer is provided with an organic layer; an organic retaining wall is arranged in an edge region of each organic layer; each organic layer is blocked in the corresponding organic retaining wall and is provided with a second inorganic layer covering the corresponding first inorganic layer, organic layer and organic retaining wall; and each organic retaining wall is filled with a water-absorbing material to improve the water-oxygen blocking ability of the OLED panel. The target of improving the blocking ability on water vapor and oxygen is achieved through arranging one organic retaining wall in the edge region of each organic layer and filling each organic retaining wall with the water-absorbing material, thereby 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 panel and a packaging method. 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 encapsulation method still makes the edge of the OLED device susceptible to water vapor and oxygen intrusion, which in turn causes phenomena such as electrode oxidation, poor chemical reaction of organic materials, or black spots, thereby reducing the service life of the OLED device. [0004] Therefore, it is necessary to provide an OLED panel and a packaging method to solve the problems e...
