Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0058]In the manufacturing process of OLED devices, the substrate to be printed involves multiple film layers, some of which can be printed by inkjet printing process, such as hole injection layer (HIL), hole transport layer (HTL), light emitting layer (EML- RGB) can already use the inkjet printing process, but generally different film layers involve different printing requirements. For example, according to the use effect, the light-emitting layer needs to be composed of pixel units of different colors. In the traditional inkjet printing technology, in order to facilitate...

Abstract

The invention relates to an inkjet printing method and device, computer equipment and a storage medium. The inkjet printing method comprises the steps that printing parameter information and to-be-printed pixel unit arrangement information are obtained, a repeated pixel unit set is selected according to the arrangement information, ink dripping position information corresponding to the repeated pixel unit set is identified according to the repeated pixel unit set, and inkjet printing is conducted according to the printing parameter information and the ink dripping position information. By adopting the inkjet printing method to conduct inkjet printing, the printing efficiency can be improved, the problem that the printing time is excessively long in the inkjet printing process is solved, the phenomenon of uneven film thickness after an ink material is dried is avoided, and the better printing effect is achieved.

Description

technical field [0001] The present application relates to the technical field of inkjet printing, in particular to an inkjet printing method, device, computer equipment and storage medium. Background technique [0002] With the development of science and technology, inkjet printing technology has emerged, and the method of using inkjet printing technology to manufacture OLED (Organic Light-Emitting Diode, organic light-emitting diode) display screens is the main process method for the production of large-size OLED display screens in the future. At present, in the manufacturing process of OLED devices, inkjet printing process has been adopted. Some of the functional materials can use the inkjet printing process, such as the hole injection layer (HIL), the hole transport layer (HTL), and the light emitting layer (EML-RGB) can already use the inkjet printing process. That is, in the known pixel unit, the functional layer material ink is dropped into the pixel unit on the subst...
