Method for preparing distribution film and equipment

Abstract

The invention relates to a method for preparing a distribution film and equipment; the method comprises the steps that: a substrate is provided and the substrate comprises a display area and a non-display area; distribution liquid is sprayed on the display area of the substrate; an interference plate is arranged right above the substrate, moves downwards along a direction which is vertical to the upper surface of the substrate to an average liquid thickness of the distribution liquid, so that the distribution liquid can be quickly and uniformly scattered in the display area; and the distribution liquid which is uniformly scattered is baked to form the distribution film. According to the method for preparing the distribution film and the equipment, after the distribution liquid is sprayed, the height of the distribution liquid can be limited through the interference plate, so that the thickness of the distribution film is ensured, the uniform scattering of the distribution liquid is ensured, the uniformity of the distribution film is improved, and the display performance and the production efficiency of the product are improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel production, in particular to a method and equipment for forming an alignment film on a substrate of a liquid crystal panel. Background technique [0002] As we all know, a thin film transistor liquid crystal display panel mainly includes a thin film transistor substrate, a color filter substrate, and a liquid crystal layer sandwiched between the thin film transistor substrate and the color filter substrate, and the thin film transistor substrate and the color filter substrate are covered with A transparent conductive film, and then cover a layer of alignment film on the transparent conductive film. The main function of the alignment film is to align the liquid crystal molecules. [0003] The way to form the alignment film in the prior art is: spray the alignment liquid from the nozzle of the nozzle onto the thin film transistor substrate and the color filter substrate, and let the ali...

Problems solved by technology

[0003] The way to form the alignment film in the prior art is: spray the alignment liquid from the nozzle of the nozzle onto the thin film transistor substrate and the color filter substrate, and let the alignment liquid stand still for a period of time to make it diffuse to form a film surface, and finally bake Baking to form an alignment film, but the drop volume of the alignment liquid ejected from the nozzle is not easy to control, and it is easy to form an uneven thickness of the alignment film, which affects the display characteristics of the product. In the prior art, it is necessary to wait for the alignment liquid to diffuse, reducing the product productivity
