Printing apparatus and method for manufacturing organic light emitting diode display

摘要

A printing apparatus includes: a nozzle head including a nozzle head main body and a plurality of linear nozzle units for spraying a printing material, the linear nozzle units on one side of the nozzle head main body and elongated in parallel in a first direction; and a nozzle head driver connected to the nozzle head main body and configured to move the nozzle head in a second direction crossing the first direction. In such a printing apparatus, a dry spot due to a printing time difference may be reduced or prevented, a uniform printing pattern may be formed, printing quality may be improved, and defective products may be reduced. In addition, the effective spacing between separate spray nozzles may be reduced or minimized.
