Abstract

The invention relates to the field of display technologies, and provides an OLED (Organic Light-Emitting Diode) display device packaging method and an OLED display device. The packaging method comprises the steps of fabricating an OLED panel on a substrate; sequentially preparing a first organic protection layer and a second inorganic protection layer on the OLED panel; preparing a metal film on the side surface of the second inorganic protection layer, wherein the metal film is flush with the upper surface of the second inorganic protection layer; preparing a third organic protection layer onthe second inorganic protection layer and the metal film; arranging glass cement on the side surfaces of the OLED panel, the first organic protection layer, the metal film and the third organic protection layer, wherein the glass cement is flush with the upper surface of the third organic protection layer; and covering the third organic protection layer and the glass cement with a cover plate above, and hardening the glass cement so as to complete the packaging. The OLED device is packaged by combining the combination of multiple films, the metal film and the glass cement, and the thermal conductivity, sealing performance and structural strength of the device are increased. The method is simple in process, conducive to cost control and capable of being applied to industrial production.

Description

technical field [0001] The invention belongs to the field of display technology, and more specifically relates to a packaging method of an OLED display device and the OLED display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, hereinafter referred to as: OLED) display device is known as an The third generation of fantasy display technology. At present, driven by the continuous capital investment and technology research and development of global manufacturers, OLED-based flat panel display technology is tending to the stage of increasingly mature mass production technology and rapid growth of market demand. [0003] For OLED display devices, the quality of encapsulation directly affects the structure and performance of the display. Possible problems in encapsulation include insufficient vacuum and poor sealing effect during the encapsulation process of the display after OLED production is completed, making moisture and oxyge...
