Problems solved by technology

[0004] However, when the nozzle is subjected to a high-pressure cleaning process, the characteristics of the inkjet head including the nozzle may change, so there is a disadvantage that the amount of liquid droplets ejected from the nozzle must be reset.
And, in the case of resetting the droplet volume, increase the restart time of the droplet ejection device accordingly

Abstract

Provided are an apparatus and a method for discharging a droplet, wherein the apparatus may comprise: a first inkjet head having a plurality of nozzles to discharge a droplet to an object body; and a second inkjet head provided to correspond to the first inkjet head to discharge a droplet to the object body instead of the first inkjet head when a disorder of any one of the nozzles of the first inkjet head occurs. According to the invention, the apparatus for discharging droplet can completely and properly discharge droplet to the object body even if the disorder of more than one nozzles in a plurality of nozzles occurs.

Description

technical field [0001] The present invention relates to a droplet discharge device and a droplet discharge method, and more particularly to a droplet discharge device having a plurality of nozzles for discharging liquid droplets onto an object such as a substrate, and a liquid droplet discharge device using the liquid droplet discharge device. droplet ejection method. Background technique [0002] At present, in the case of forming an alignment film or coating UV ink on a substrate (for example, a transparent substrate) used for manufacturing a liquid crystal display device, or in the case of forming a color filter on a substrate used for manufacturing an organic light-emitting display device , using a printing device having an inkjet head, for example, using a droplet ejection device. [0003] In the droplet discharging process using the inkjet head, it is necessary for the plurality of nozzles of the inkjet head to smoothly discharge the liquid droplets onto the substrate...
