Abstract
The present invention provides an OLED encapsulation method, which comprises frit coated on a cover plate to correspond to an outer circumference of an OLED device and a water-contact-to-release-heat layer formed on a backing plate to correspond to the frit. The cover plate and the backing plate are laminated together to make the frit contacting the water-contact-to-release-heat layer. Afterwards, a water-contained gas is introduced to cause reaction of the water-contact-to-release-heat layer to release heat so as to heat and melt the frit for bonding the cover plate and the backing plate, and compared to the prior art, there is no need of a laser based operation so that the cost of laser facility can be saved, the manufacturing cost can be reduced, and also, the heat generated by the water-contact-to-release-heat layer is controllable and uniform, so that the effect of encapsulation is good and product yield is high.
