Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0022] Where possible, the same or similar parts will be given the same reference numerals in the drawings.

[0023] As mentioned in the background art, the film layer prepared by inkjet printing has the problem of uneven thickness. For example, as a next-generation display technology, OLED display devices have been widely used in mobile phones and other devices in recent years. At present, the core of the production of OLED display devices is evaporation technology, but the evaporation technolo...

Abstract

The invention provides an inkjet printing device and an inkjet printing method, and relates to the technical field of display. The inkjet printing device is used for spraying printing ink to a targetsubstrate and comprises an inkjet assembly and a heating assembly, wherein the inkjet assembly comprises a nozzle for spraying the printing ink; the heating assembly comprises an emitting nozzle for emitting heat source beams; and the heat source beams are used for heating the printing ink on the target substrate, and energy density of each heat source beam is decreased progressively from center to the periphery on the cross section of the heat source beam. According to the embodiment, the energy density of each heat source beam is decreased progressively from center to the periphery on the cross section of the heat source beam, so that the increase speed of the solidification rate of the intermediate region of the printing ink in accommodating holes is higher than that of the solidification rate of the edge region, and the printing ink flowing from the intermediate region to the edge region can be reduced.

Description

technical field [0001] The present application relates to the technical field of inkjet printing, in particular to an inkjet printing device and an inkjet printing method. Background technique [0002] At present, the film layer prepared by inkjet printing has the problem of uneven thickness. Therefore, how to improve the uniformity of the film layer prepared by inkjet printing technology has become an urgent problem to be solved. Contents of the invention [0003] In view of this, the embodiments of the present application are dedicated to providing an inkjet printing device and an inkjet printing method, so as to solve the problem of poor uniformity of the film layer prepared by the inkjet printing technology in the prior art. [0004] One aspect of the present application provides an inkjet printing device, comprising: at least one inkjet assembly, including nozzles for spraying the ink; and at least one heating assembly, including nozzles for emitting heat source beam...
