Printing control method, device and system and storage medium

Abstract

The invention relates to a printing control method, a printing control device, a printing control system and a computer readable storage medium. The printing control method comprises the following steps that a preset nozzle is selected, and the preset nozzle is the nozzle closest to a current printing pixel unit in nozzles corresponding to an unprinted area when printing is interrupted; the preset nozzle is controlled to jet ink; the dripping position of ink drops sprayed out when the preset nozzle jets ink on the substrate is obtained; the ink droplet is controlled to be located at the dripping position when the preset nozzle jets ink during re-printing, and printing is continued. By adopting the printing control method, the printing position during printing interruption can be marked, and then printing can be continued according to the original printing parameters so that the scrap cost of the substrate can be effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of inkjet printing, in particular to a printing control method, a printing control device, a printing control system and a computer-readable storage medium. Background technique [0002] In the production process of functional devices, inkjet printing is a commonly used processing method. For example, functional devices such as organic light-emitting diodes (OLEDs) or quantum dot light-emitting diodes (QLEDs) are fabricated by inkjet printing. Specifically, the corresponding functional material ink can be injected into the pixel unit by inkjet printing to prepare the corresponding functional layer. For example, a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML), etc. are prepared by inkjet printing. figure 1 A form of inkjet printing is shown in . Nozzles are provided on the inkjet printing head 101 , and functional material ink droplets 401 are injected into the p...

AI Technical Summary

Problems solved by technology

[0003] In the actual inkjet printing process, you may encounter the problem of printing interruption due to abnormal equipment and other reasons. When printing interruption occurs, there is no good remedy in the traditional printing method, and even the substrate needs to be scrapped.

However, since the manufacturing cost of the substrate is inherently high, and the inkjet printing of some pixel units on the substrate has been completed at this time, the scrapping treatment in this case will greatly increase the scrapping cost of the substrate
