Manufacturing method for 3D (three-dimensional) lens, 3D lens and 3D glasses

Abstract

The invention discloses a manufacturing method for a 3D (three-dimensional) lens, the 3D lens and 3D glasses. The method comprises the following steps of manufacturing front sheet glass, rear sheet glass, a front polarizer and a rear polarizer respectively; fixing the front and rear sheet glass to form a liquid crystal box by using an adhesive, and filling liquid crystals in the liquid crystal box formed by the front and rear sheet glass; orthogonally arranging the front and rear polarizers on the two sides of the liquid crystal box, wherein the front polarizer is arranged on one side of the front sheet glass, the rear polarizer on one side of the rear sheet glass, the outer edge of the front polarizer is flush with the inner edge of the liquid crystal box, and the outer edge of the rear polarizer is flush with the outer edge of the rear sheet glass, or the outer edge of the rear polarizer is flush with the inner edge of the liquid crystal box, and the outer edge of the front polarizer is flush with the outer edge of the rear sheet glass. According to the technical scheme, the problem that the edges of lenses are blacked to seriously influence the attractive appearance of a product when the conventional 3D glasses are in an off-state can be solved.

Description

technical field [0001] The invention relates to the technical field of 3D video, in particular to a manufacturing method of a 3D lens, a 3D lens and 3D glasses. Background technique [0002] In the existing technical solution, the LCD module in the 3D lens usually includes: upper and lower glass, the liquid crystal filled between the upper glass and the lower glass, which is consistent with the size and shape of the upper and lower glass, and the front polarized direction is perpendicular to each other. Composed of polarizer and rear polarizer. Wherein, the size and shape of the upper glass and the lower glass are the same. In the manufacturing process of the LCD module in the 3D lens, it is also necessary to use adhesives (such as epoxy resin, etc.) to fix the front glass sheet and the rear glass sheet together, and to fill the liquid crystal between the front glass sheet and the rear glass sheet . [0003] The characteristic of the polarizer is that only the polarized l...
