Apparatus of encapsulating display panel and method of manufacturing organic light emitting display device using the same
View Patent ↗An encapsulation apparatus capable of securely sealing a gap of a display panel and improving intensity of the display panel, and a method of manufacturing an organic light emitting display device using the encapsulation apparatus are taught. The encapsulation apparatus includes an injection port having tapered projecting edges formed in both sides of one end the injection port, and injecting a reinforcing material into a gap of a display panel in a dual surface contact manner, the first substrate and the second substrate being attached to each other using a sealant; and a supporter coupled to the injection port and supporting the injection port.
1. A method of manufacturing an organic light emitting display device, the method comprising:
adhering a second substrate of the organic light emitting display device comprised of a first substrate having an organic light emitting diode installed therein and the second substrate for encapsulating a pixel region of the first substrate, to the first substrate using a sealant;
immersing an injection part of an encapsulation apparatus in a liquid reinforcing material and taking the injection part out of the liquid reinforcing material, the injection part having tapered projecting edges formed in one end of the injection part;
contacting the reinforcing material with a gap of the display panel, the reinforcing material being disposed on the projecting edges and the display panel being composed of the adhered substrates; and
curing the reinforcing material with which the gap of the display panel is filled.
2. The method of manufacturing the organic light emitting display device of claim 1 , in which the injection part has a recess between the projecting edges.
3. The method of manufacturing the organic light emitting display device of claim 1 , wherein the reinforcing material includes at least one selected from the group consisting of epoxy, acrylate, urethane acrylate, and acrylcyanoate.
