[0063] see figure 1 , figure 1 A flow chart showing a method for manufacturing a display device provided by an embodiment of the present invention includes the following steps:

[0064] S1. Provide a substrate with a pixel cavity on the substrate;

[0065] Wherein, the provided substrate has been subjected to ITO patterning treatment, and the substrate has a pixel cavity for placing ink, and the pixel cavity is defined by the pixel bank on the substrate.

[0066] S2, placing ink in the pixel cavity of the substrate to obtain the printed device 1;

[0067] In this step, the inkjet printing technology is used to place ink in the above-mentioned pixel cavity, that is, a liquid film is printed on the substrate, and the ink forms an ink layer on the pixel cavity of the substrate to obtain the printed device 1, and the printed device 1 is composed of the substrate formed by forming an ink layer on top. Wherein, the ink is an organic ink, which includes a solvent and solute molec...

Abstract

The invention is applicable to the technical field of panel display, and provides a display device, a preparation method thereof and a drying device, and the method comprises the steps: providing a substrate which is provided with a pixel cavity; placing ink in the pixel cavity of the substrate to obtain a printing device; drying the printing device, and applying an electric field to the printing device in the drying process; and packaging the dried printing device to obtain the display device. The display device is prepared by the preparation method of the display device. The electric field is applied to the printing device in the drying treatment process of the printing device, the motion state of solute molecules of ink on the printing device can be changed, the wettability of the ink is adjusted, the drying rate consistency of the ink on the printing device during drying is improved, and therefore the film forming uniformity of the ink during drying is improved. In addition, by adjusting the electric field, the orientation consistency of solute molecules in the ink can be improved, the carrier mobility can be improved, and the use performance of a display device can be improved.

Description

technical field [0001] The invention belongs to the field of flat panel display technology, and more specifically relates to a display device, a preparation method thereof, and a drying device. Background technique [0002] In display technology, inkjet printing technology can greatly improve the utilization rate of materials and reduce production costs. It is a research hotspot in the production process of large-size panels such as OLED and QLED. In the manufacturing process of the display device, an organic ink is usually printed in the pixel cavity of the ITO-patterned substrate by inkjet printing technology, and then the ink is dried to obtain a functional layer. [0003] However, in the manufacturing process of the display device, the following problems still exist: [0004] 1. The pixel cavity of the display device is very small, and the wettability requirements for the ink and the substrate are very high; and in the current drying process of the ink, a "coffee ring" ...
