Abstract

The invention provides an OLED packaging device. The OLED packaging device comprises a base, a bearing platform, a driving assembly, a glue storage pipe and a coating glue pretreatment assembly; the bearing platform is fixed to the base and used for bearing a packaging panel; the driving assembly is fixed to the base; the glue storage pipe is installed on the driving assembly and used for containing coating glue; and the coating glue pretreatment assembly is connected with the glue storage pipe and comprises a containing cavity, ultraviolet light sources, a glue pipe and a glue coating head, wherein the glue pipe is arranged in the containing cavity, a glue inlet of the glue pipe is connected with the glue coating head, and the ultraviolet light sources are arranged on the inner wall of the containing cavity. A packaging adhesive material in a coating component is subjected to ultraviolet irradiation and then coated so that the coating amount can be effectively controlled, waste is avoided, meanwhile, a first substrate is prevented from being irradiated by ultraviolet light in the packaging process, and the electrical property of the substrate is ensured.

Description

technical field [0001] The invention relates to the display field, in particular to an OLED packaging device. Background technique [0002] Organic Light Emitting Device (OLED) has attracted much attention in the industry due to its self-luminescence, low driving voltage, fast response, and wide viewing angle. Organic light-emitting materials are very sensitive to water and oxygen, and the presence of trace amounts of moisture can lead to a serious decline in display quality or even complete failure, so packaging is very important for OLEDs. [0003] The packaging methods of traditional large-size OLED display panels mostly use UV-curable glue, mainly by first coating the frame glue, and then coating the filling glue inside the frame glue, and then using ultraviolet radiation to cure the frame glue and coating glue. However, in the process of ultraviolet irradiation, ultraviolet rays will have an impact on the electrical properties of OLED display panels. In the prior art, ...
