Abstract
An inkjet printing device and method are provided. The inkjet printing device includes a nozzle head; and the nozzle head is provided with a main printing unit and an auxiliary printing unit which share a common liquid supplying pipeline. The main printing unit is located at a middle of the nozzle head and is configured to perform inkjet printing of pixel patterns. The auxiliary printing unit is located at an edge of the nozzle head and is configured to perform inkjet printing of protective patterns. The protective patterns are configured to produce a solvent-protective atmosphere for the pixel patterns at an edge of every printing process.
Claims20
An inkjet printing device, comprising:
- a nozzle head, the nozzle head being provided with a main printing unit and an auxiliary printing unit which share a common liquid supplying pipeline, the main printing unit being located at a middle of the nozzle head and being configured to perform inkjet printing of pixel patterns, the auxiliary printing unit being located at an edge of the nozzle head and being configured to perform inkjet printing of protective patterns, and the protective patterns being configured to produce a solvent-protective atmosphere for the pixel patterns at an edge of every printing process, wherein the main printing unit comprises a plurality of first nozzles located at a middle of the nozzle head, the plurality of first nozzles being disposed at an equal interval;
- and the auxiliary printing unit comprises a second nozzle located at an edge of the nozzle head, a distance from the second nozzle to an outermost first nozzle being smaller than a distance between adjacent first nozzles.
An inkjet printing device, comprising:
- a nozzle head, the nozzle head being provided with a main printing unit and an auxiliary printing unit which share a common liquid supplying pipeline, the main printing unit being located at a middle of the nozzle head and being configured to perform inkjet printing of pixel patterns, the auxiliary printing unit being located at an edge of the nozzle head and being configured to perform inkjet printing of protective patterns, and the protective patterns being configured to produce a solvent-protective atmosphere for the pixel patterns at an edge of every printing process;
- and
- a controlling device configured to independently control the main printing unit and the auxiliary printing unit.
An inkjet printing method, comprising:
- aligning a main printing unit to be located above pixel layouts of a printing substrate while aligning an auxiliary printing unit to be located above protective layouts of the printing substrate;
- connecting both the main printing unit and the auxiliary printing unit to a common liquid supplying pipeline, and independently controlling inkjet printing solutions, respectively;
- and
- displaying pixel patterns on the pixel layouts while producing a solvent-protective atmosphere on the protective layouts to allow a uniform film being formed at an edge of every printing process.
