OLED (Organic Light Emitting Diode) packaging structure and method

Abstract

The invention provides an OLED (Organic Light Emitting Diode) packaging structure and an OLED packaging method. The OLED packaging structure comprises a packaging cover plate, a base plate, an OLED device, a metal oxide layer, frame glue, drying agent fillers and sintered glass, wherein the base plate is opposite to the packaging cover plate; the OLED device is positioned between the packaging cover plate and the base plate and is arranged on the base plate; the metal oxide layer is formed on the surface of the OLED device; the frame glue is arranged at the periphery of the OLED device and is used for gluing the packaging cover plate and the base plate; the drying agent fillers are filled in an internal space, which is positioned between the packaging cover plate and the base plate and is enclosed by the frame glue, and cover the OLED device; the sintered glass is arranged at the periphery of the frame glue and is used for gluing the packaging cover plate and the base plate. According to the structure, the frame glue and the sintered glass are used for packaging; meanwhile, the interior of the frame glue is filled with the drying agent fillers, so that the packaging structure has excellent sealing property and high mechanical strength; moreover, the metal oxide layer is formed on the surface of the internal OLED device, so that the problems of non-uniform brightness of a display and the like caused by the fact that light emitting elements are corroded by the drying agent fillers, particularly liquid-stage drying agents are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED packaging structure and a packaging method thereof. Background technique [0002] OLED is an Organic Light-Emitting Diode (Organic Light-Emitting Diode), which has the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. It began to gradually replace traditional liquid crystal displays and was widely used in mobile phone screens, computer monitors, full-color TVs, etc. Unlike traditional liquid crystal display technology, OLED display technology does not require a backlight, and uses very thin coatings of organic materials and glass substrates that emit light when an electric current passes through them. However, because organic materials are easy to react with water vapor or oxygen, as a display device based on organic materials, OLED displays have very high requirements for packaging. [00...

AI Technical Summary

Problems solved by technology

However, the glass powder laser sealing technology is not suitable for large-sized panels due to the gaps in the panel. As the panel size increases, the panel is prone to bending, affecting the display effect, and easily broken.
