Abstract
A method of manufacturing the light emitting package structure is provided. The method includes: a preparation process: mounting a light emitting unit on a substrate; a dispensing process: coating a sealant on a first joint area of the substrate; a cover-enclosing process: disposing a cover element having a second joint area on the substrate, the first joint area and the second joint area joined to each other by the sealant; a vacuum process: reducing an ambient pressure to a first pressure lower than the original ambient pressure; a pressure-adjusting process: adjusting the ambient pressure around the package structure to a second pressure higher than the first pressure; and a curing process: curing the sealant.
