A thin film manufacturing method, manufacturing equipment, display substrate and manufacturing method thereof

Abstract

The present invention provides a film production method, production equipment and display substrates and its production methods. The production method of the film includes: provides a substrate with a pixel definition layer; ink in the pixel definition of the pixel definition layer;Dry treatment of ink to form a thin film. During the drying of ink, the control electric field is formed, enabling the solution in the ink to move the predetermined edge of the pixel area to the center area of the pixel area under the action of the ink.The nail effect of the pixel definition layer is resisting, and the climbing phenomenon of weakening ink on the pixel edge area makes the thickness of the film in the pixel area consistent and play a flat role, which is conducive to improving the device that has the film that has the film.Lighting is uniform, and then improves the efficiency and life of the device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film manufacturing method, manufacturing equipment, a display substrate and a manufacturing method thereof. Background technique [0002] In the display field of electroluminescent devices, the thin film deposition of functional layers (such as light-emitting layers) is usually performed by solution process. Such solution processes include, but are not limited to, inkjet printing, spin coating, screen printing, and transfer printing, among others. An essential step in these wet film-forming processes is that the solvent needs to be removed through a subsequent drying process, so that the solute is dried to form the desired film. And this drying process to remove the solvent has a crucial influence on the morphology of the formed film. For optoelectronic display devices, the poor morphology and uniformity of the dry film have a great impact on the life of the device and ...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the present invention provides a thin film manufacturing method, manufacturing equipment, display substrate and its manufacturing method, which are used to solve the serious climbing phenomenon of ink on the edge of the pixel when the thin film in the pixel is formed by the method of the solution process, thereby It is difficult to ensure the flatness of the formed film, resulting in uneven lighting brightness of the device, and the problem that the utilization efficiency of the material is greatly reduced
