Ink filling element carrier, control method and device of ink filling element carrier, and computer equipment

Abstract

The invention relates to an ink filling element carrier, a control method and device of the ink filling element carrier, and computer equipment, wherein the carrier comprises a carrier body and a plurality of groups of fixing pieces arranged on the carrier body, and each fixing piece is used for loading one ink filling element; each fixing piece is arranged in a first direction, wherein the firstdirection is a relative moving direction of the corresponding ink filling element and a printed substrate in a printing process; and when the ink filling elements are loaded on the fixing pieces, eachfixing piece can drive the corresponding ink filling element to move in a second direction, wherein the second direction is a direction perpendicular to the first direction in a plane parallel to theprinted substrate. According to the ink filling element carrier, the number of nozzles dripping ink to the same pixel pit can be flexibly regulated and controlled according to the sizes of pixel pitson the printed substrate; and when the sizes of the pixel pits on the substrate are small and the number of the pixel pits is increased, the number of nozzles dripping ink to the same pixel pit is increased, so that the printing process time is shortened, and the film forming uniformity of the substrate is improved.

Description

technical field [0001] The present invention relates to the technical field of inkjet printing, in particular to an ink-filled element carrier and its control method, device, computer equipment and computer-readable storage medium. Background technique [0002] Fabrication of organic light-emitting diode (Organic Light-Emitting Diode, OLED) display screens by using an inkjet printing process 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. Such as figure 1 As shown, the functional layer material ink is injected into the pixel pits on the substrate by inkjet printing. [0003] Inside inkjet printing equipme...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to address the fact that the existing inkjet printing equipment has small pixel pits on the substrate and the number of pixel pits increases, the printing process time of the substrate is significantly increased, resulting in poor film formation uniformity of the printed substrate, which affects the preparation process. Technical problem of device efficiency, providing an ink-filled component carrier and its control method, device and computer equipment
