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.

This application claims priority to and the benefit of Korean Patent Application No. 10-2012-0043914, filed in the Korean Intellectual Property Office on Apr. 26, 2012, the entire content of which is incorporated herein by reference.
(a) Field
Aspects of embodiments of the present invention relate to a printing apparatus and a manufacturing method of an organic light emitting diode (OLED) display using the printing apparatus.
FIG. 1 is a schematic diagram of a printing apparatus according to an exemplary embodiment of the present invention.
FIG. 2 is a schematic view of a nozzle head of the printing apparatus of FIG. 1.
FIG. 3 is an enlarged view showing a portion of the nozzle head of FIG. 2.
A printing apparatus and a manufacturing method of an OLED display according to exemplary embodiments of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the exemplary embodiments disclosed hereinafter, but may be implemented in various different forms. The exemplary embodiments described herein provide explanation of the invention to a person of ordinary skill in the art. Like reference numerals refer to like elements throughout.
In the drawings, the thickness of layers, films, panels, regions, etc., may be exaggerated for clarity. Further, it will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present.
In addition, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising” will be understood to imply the inclusion of stated elements but not the exclusion of any other elements. Further, throughout the specification, “on” implies being positioned above or below a target element and does not imply being necessarily positioned on top based on a gravity direction.
