Problems solved by technology

Regardless of the inkjet method, there is a common problem: during the drying process, the edge area of ​​the printed substrate (including the edge area of ​​each swath (English: swath), the outside of which is the clearance area) is due to the interaction with other central areas ( The solution atmosphere in the solution area) is different, resulting in the inconsistent thickness and outline of Pixel pixels in the edge area and other areas (with obvious differences), resulting in abnormalities

Abstract

The invention discloses a nozzle, an inkjet printing method and a continuous inkjet printing method. A guiding ink inlet, a main ink inlet, a first guiding inkjet channel, a main inkjet channel and a second guiding inkjet channel are arranged on the nozzle. The guiding ink inlet and the main ink inlet are mutually independent; the first guiding inkjet channel and the second guiding inkjet channel are located on the two sides of the main inkjet channel; the guiding ink inlet communicates with the first guiding inkjet channel and the second guiding inkjet channel; liquid entering into the guiding ink inlet is sprayed after passing through the first guiding inkjet channel and the second guiding inkjet channel; the main ink inlet communicates with the main inkjet channel; and liquid entering into the main ink inlet is sprayed after passing through the main inkjet channel. When the nozzle provided by the invention is in use, the drying speed of each swath edge area in the printing process of multiple swathes can be slowed down, so that the drying speed is consistent with the drying speed of an inner area, and it is guaranteed that the pixel thickness and contour of each printing swath edge area are consistent with those of the inner area.

Description

technical field [0001] This article relates to the field of panel technology, especially a spray head, an inkjet printing method and a continuous inkjet printing method. Background technique [0002] Compared with LCD (liquid crystal display), organic electroluminescent devices (OLEDs) have the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright colors, light and thin, etc., and are considered to be the next generation display technology. [0003] OLED film-forming methods mainly include evaporation process and solution process. The evaporation process is relatively mature in small-scale applications, and this technology has been applied in mass production. The solution process OLED film-forming methods mainly include inkjet printing, nozzle coating, spin coating, screen printing, etc. Among them, inkjet printing technology is considered to be a large-scale OLED technology due to its high material utilization rate and large-scale real...
