Ink-jet printing method, device and equipment

Abstract

The invention provides an ink-jet printing method, device and equipment. The ink-jet printing method comprises the steps that an alignment command is received, an alignment mark protection cover of ajet nozzle is opened to expose an alignment mark on the jet nozzle, the position of the jet nozzle is adjusted according to the alignment mark, a printing command is received, the alignment mark protection cover is closed according to the printing command to cover the alignment mark on the jet nozzle, and ink-jet printing is carried out. The alignment mark protection cover is arranged on the alignment mark and is only opened when alignment is needed to expose the alignment mark, and the alignment mark cover is closed to cover the alignment mark when printing is needed, so that it is avoided that the alignment mark is contaminated as ink splashes on the alignment mark in the printing process, the effective alignment of the jet nozzle is ensued, and the printing precision is ensured.

Description

technical field [0001] The present application relates to the display field, in particular to an inkjet printing method, device and equipment used in the display field. Background technique [0002] In the prior art, various product manufacturing methods in the display field tend to be produced by inkjet printing. In the process of inkjet printing, it is necessary to pre-align the nozzle to confirm whether the position of the nozzle is correct. However, for The alignment mark is often very close to the nozzle. When the ink is ejected, the ink will often splash onto the nozzle, thus polluting the alignment mark, which will cause the nozzle to fail to perform effective alignment and affect the printing accuracy. Contents of the invention [0003] The present application provides an inkjet printing method, device and equipment to improve the accuracy of inkjet printing. [0004] A method of inkjet printing, comprising: [0005] receiving an alignment instruction, and openin...
