Problems solved by technology

Although this method has the advantage of being able to produce tiny and uniform droplets in the range of several hundred nm to 5 μm, the liquid conductivity should be at least 10. -4 S / m limitation, and the amount of liquid sprayed is 10 -10 ~10 -9 m 3 / sec, very limited and therefore difficult to apply in mass production processes

Abstract

Provided herein is a spray nozzle and a coating system using the same, comprising: a liquid nozzle injecting liquid towards a substrate; a gas nozzle for injecting gas to collide with the liquid on an injection path of the liquid to perform a primary atomization of the liquid; and a voltage supply connected to the liquid nozzle, the voltage supply for applying voltage to the liquid nozzle to generate an electric field between the liquid nozzle and substrate to perform a secondary atomization of the liquid.

Description

technical field [0001] The present invention relates to a spray nozzle and a coating system using the spray nozzle, and in more detail to a spray solution capable of atomizing the spray solution in stages, stably spraying small droplets of uniform size, and increasing the spray volume, thereby A spray nozzle capable of being used in a mass production process and a coating system using the spray nozzle. Background technique [0002] Coating processes are indispensable in the manufacturing processes of displays, solar cells, etc., not only in traditional industrial fields such as automobiles and construction. In particular, in the manufacture of displays such as organic solar cells and organic light emitting diodes (Organic Light Emitting Diodes: OLEDs), it is necessary to perform fine coating with a thickness of several tens of nm to several hundred nm. In addition, the roughness and uniformity of the coating surface have a great influence on product performance, so it is ne...
