Abstract

The invention discloses an ink-jet printing method, an ink-jet printing device, ink-jet printing equipment and a computer-readable storage medium. The method is applied to an organic light-emitting device thin film, and comprises the following steps of acquiring a current position of a printing head of an ink-jet printer; and adjusting the moving distance of the printing head of the ink-jet printer according to the current position. The ink jet printing method is capable of controlling the thickness of the film surface by adjusting the moving distance of the printing head of the ink jet printer so that the problem of uneven thickness of the film surface caused by capillary flow and a Marangoni effect can be solved. Compared with the prior art in which the thickness of the film surface is controlled by adjusting the type and proportion of solvents, the ink jet printing method is low in cost, and can avoid the situation that an additive influences the performance of a device.

Description

technical field [0001] The present invention relates to the technical field of inkjet printing, in particular to an inkjet printing method, device, equipment and computer-readable storage medium. Background technique [0002] At present, OLED display devices mainly use vacuum semiconductor technology to prepare high-quality organic thin films. However, it is difficult for this technology to achieve uniform preparation of OLED panels larger than 55 inches. At the same time, its low material utilization rate and high cost are the bottlenecks restricting the large-scale development of OLED. As a non-contact printing technology, inkjet printing has the advantages of high material utilization rate, flexible processing, and patterning processing without a mask, and has become the most promising method for processing and preparing large-area flexible OLED displays. Screen film forming technology. [0003] When the inkjet printing process is used to prepare OLED light-emitting pa...
