Title:
COATING METHOD, COATING APPARATUS AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/072545
Kind Code:
A1
Abstract:
A coating method, a coating apparatus and a light-emitting device. The coating method comprises: controlling an ink supply device to stop supplying ink to a micro nozzle (40) when it is determined that the lowest end of an ink droplet (50) from the micro nozzle (40) reaches a first position (step S102); determining that the distance between the end of the micro nozzle (40) and a substrate (20) reaches a second distance, the second distance being preset (step S104); controlling the ink supply device to continue to supply ink, and controlling the micro nozzle (40) to move relative to the substrate (20) so as to coat in a pattern (step S106). The invention provides a good pattern forming solution, thereby avoiding the technical problem in the prior art of inkjet printing apparatuses easily causing nozzle clogging.
