Dispenser and method of fabricating organic light emitting display device using the same

摘要

A dispenser capable of forming a uniform material layer and a method of fabricating an organic light emitting display device using the same are disclosed. The dispenser includes a syringe including a coating material and provided with a nozzle for ejecting the coating material to a substrate and a syringe cap for controlling a coating amount from the nozzle, a pressing unit providing a pressure for ejecting the coating material, a transporting unit for moving the syringe above, and a cap-driving unit for driving the syringe cap to control the coating amount.

主权项

1. A method of fabricating an organic light emitting display device using a dispenser, the method comprising:
preparing a substrate; forming an organic light emitting device on the substrate; forming a first protective layer on the substrate to cover the organic light emitting device and a portion of the substrate; forming a second protective layer on the first protective layer by coating an organic material; forming a third protective layer on the first protective layer and the second protective layer to cover the second protective layer and the first protective layer; forming a sealing material layer on the third protective layer; and aligning a seal cap on the sealing material layer, wherein the forming of the second protective layer is performed by use of a dispenser comprising a nozzle and a syringe provided with a syringe cap to control a coating amount of the nozzle, wherein the nozzle has a plurality of nozzle hole groups, each comprising at least one nozzle hole; and wherein the plurality of nozzle hole groups have at least one of different numbers of the nozzle holes, different cross-sectional areas of the nozzle holes, different shapes of the nozzle holes, and different average cross-sectional areas of the nozzle holes.
