Abstract

The invention provides an ink-jet printing device and printing method as well as a preparation method of a light-emitting device. The ink-jet printing device comprises a spray head and a magnetic control unit, wherein the spray head comprises a plurality of nozzles and a plurality of liquid outlet pipelines, and the nozzles and the liquid outlet pipelines are in one-to-one correspondence; each nozzle is provided with a nozzle opening, magnetic balls are arranged in the nozzles, and the size of the magnetic balls is matched with that of the nozzle openings, and therefore, the magnetic balls cannot fall out from the nozzle openings. When the magnetic balls are in a non-magnetic-field state, the magnetic balls can fall into the nozzles based on gravity, so that air inflow from the nozzle openings is reduced; and meanwhile, ink is prevented from blocking the nozzle openings, and therefore, blockage of the ink-jet printing device caused by drying of the ink can be reduced.

Description

technical field [0001] The invention relates to the field of inkjet printing technology, in particular to an inkjet printing device, an inkjet printing method and a method for preparing a light-emitting device. Background technique [0002] The most common problem encountered in inkjet printing is nozzle clogging. Nozzle clogging will lead to changes in the volume and direction of ink output. It is mainly caused by residual ink after drying. After long-term use, the clogging will extend to the top of the nozzle and block the entire pipeline. Cleaning is more difficult than cleaning a clogged nozzle and can be done by soaking in a good solvent, requiring prolonged soaking and potentially damaging the nozzle. In the prior art, nozzle clogging is reduced by changing the ink formula, but because the ink needs to consider many factors, it is usually difficult to adjust the formula, and it is also possible to store the nozzle in the same solvent atmosphere as the ink, so that the ...
