Problems solved by technology

In the inkjet printing process, when injecting droplets, the droplets from different print heads need to be aligned with the corresponding pixels. The position accuracy of the droplets is the main technical bottleneck at present, and the positioning of the droplets is slightly deviated. can cause an error in the entire printing plate
With the improvement of product resolution and the reduction of pixel size, higher requirements are placed on the positioning accuracy of droplets. Therefore, printing errors caused by inaccurate positioning are more frequent

Abstract

The present invention provides a deflector, an inkjet printing method, equipment, a display substrate, and a manufacturing method and device thereof. The deflector includes a plate-shaped body, and the plate-shaped body includes a first surface opposite to a second surface. On the two sides, a plurality of through-slots are provided on the plate-shaped body, each of the through-slots passes through the first surface and the second surface, and each of the through-slots includes a The first opening on the surface and the second opening formed on the second surface, the opening area of ​​the first opening is larger than the opening area of ​​the second opening. The deflector provided by the invention can ensure inkjet printing accuracy and improve printing yield.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a deflector, an inkjet printing method, equipment, a display substrate and a manufacturing method and device thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display is called a next-generation display technology because of its advantages such as self-illumination, wide viewing angle, and flexibility. In the manufacturing process of the OLED display, an organic light-emitting layer is usually formed by an inkjet printing process. In the inkjet printing process, when injecting droplets, the droplets from different print heads need to be aligned with the corresponding pixels. The position accuracy of the droplets is the main technical bottleneck at present, and the positioning of the droplets is slightly deviated. can lead to errors in the entire printing plate. With the improvement of product resolution and the red...
