Abstract:
A packaging method for an OLED device, including: opening at least one through hole in a cover plate in a region between the region for forming glass cement and the region for applying UV glue; regulating the pressure in a cell-assembling chamber to a first pressure, and cell-assembling a back plate with the cover plate placed on a base board in the cell-assembling chamber with the first pressure lower than the atmospheric pressure; regulating the pressure in the cell-assembling chamber to the atmospheric pressure; curing the UV glue; regulating the pressure in the cell-assembling chamber to a second pressure that is lower than the atmospheric pressure and higher than the first pressure and detaching the cover plate from the base board; and sealing the through hole in the cover plate; and sintering the glass cement.
