Gradual color changing base plate preparing device and gradual color changing base plate preparing method

Abstract

The invention provides a gradual color changing base plate preparing device and a gradual color changing base plate preparing method. The gradual color changing base plate preparing device comprises a vacuum coating chamber, a first installing part, a second installing part, a drive part and a baffle. The vacuum coating chamber is used for containing the first installing part, the second installing part and the baffle. The first installing part is used for installing a base plate to be coated. The base plate comprises a first surface and a second surface which are oppositely arranged. The second installing part is used for installing a coating source. The coating source is adjacent to the first surface of the base plate and is used for providing a coating material. The drive part is used for driving the vacuum coating chamber to rotate. The baffle is arranged between the base plate and the coating source. The baffle comprises at least one shielding unit, the different parts of the shielding unit are different in width, and the shielding unit is used for conducting uneven shielding on the coating material sent by the coating source so that an optical film with the thickness linearly changing can be formed on the first surface.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a gradient color substrate preparation device and a gradient color substrate preparation method. Background technique [0002] Cover Glass (CG) is widely used in electronic products, but it is difficult to directly form a color gradient effect with high precision on the cover glass. At present, the gradation effect is generally achieved by spraying and other processes. The colored liquid paint is sprayed onto the surface of the glass substrate, and the color gradation is achieved by controlling the spraying angle to achieve uneven coating thickness. There are also two-color spraying, which sprays two different colors or glossy coatings on the same glass substrate. However, due to the surface tension between the glass substrate and the paint, it is easy to accumulate oil on the edge, and the effect is not ideal. When spraying, the requirements for the angle of the spray gun a...

AI Technical Summary

Problems solved by technology

However, due to the surface tension between the glass substrate and the paint, it is easy to accumulate oil on the edge, and the effect is not ideal. The angle of the spray gun is high when spraying, the waste of paint is serious, and the control of the gradual interface is difficult.
