Method for curing UV-curable resin and method for packaging OLED

摘要

The present invention provides a method for curing a UV-curable resin and a method for packaging an OLED. The method for curing a UV-curable resin includes (1) providing a UV light source and activating the UV light source to carry out a first irradiation operation on UV-curable resin; (2) de-activating the UV light source and, after a time interval of 10-300 seconds, activating the UV light source to carry out a second irradiation operation on the UV-curable resin; and (3) repeating step (2), until the UV-curable resin is completely cured. Interval-separated irradiation operations are applied so as to effectively lower down the temperature of a glass substrate and effectively avoid deterioration of an organic function layer caused by an excessively high temperature, thereby improving the lifespan and quality of an OLED device.

主权项

1. A method for curing a UV (Ultraviolet)-curable resin, comprising the following steps:
(1) providing a UV light source and activating the UV light source to carry out a first irradiation operation on a UV-curable resin having a predetermined quantity coated on a substrate; (2) de-activating the UV light source and, after a time interval of 10-300 seconds, activating the UV light source to carry out a second irradiation operation on the UV-curable resin, wherein the time interval between the de-activation of the first irradiation operation and the activation of the second irradiation operation is determined according to cooling rate of the substrate in order to control a maximum temperature of the substrate resulting from the irradiation operations to be lower than a predetermined level; and (3) repeating step (2) until the UV-curable resin is completely cured with the maximum temperature of substrate being controlled to be lower than the predetermined level.
