Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] The preparation method of reflective polarizing film based on 3D printing of the present invention comprises the following steps:

[0035] Step S1, establish a three-dimensional digital model of the reflective polarizing film, and convert it into a work instruction for controlling the work of the 3D printing device, including the first instruction for printing the first refractive index film of the reflective polarizing film and the second instruction for printing the reflective polarizing film. Second instruction for refractive index films.

[0036] Step S2, put the first raw material for printing the first refractive index film and the second raw material for printing the second refractive index film into the feeding chamber of the 3D printing device respectively, and convert the first raw material and the second raw material into a li...

Abstract

The invention relates to a 3D printing-based reflective polarizing film preparation method which comprises the following steps: 1, a three-dimensional digital model of a reflective polarizing film is established and converted to work instructions for controlling operation of 3D printing equipment, and the work instructions contain a first instruction for printing a first refractive index film of the reflective polarizing film and a second instruction for printing a second refractive index film of the reflective polarizing film; 2, a first raw material and a second raw material are respectively put into a charging cavity of the 3D printing equipment to be converted to a liquid state; and 3, the 3D printing equipment alternately executes the first instruction and the second instruction, a print head alternately sprays a first liquid raw material and a second liquid raw material onto a molding area, the sprayed raw materials are solidified quickly, and the reflective polarizing film having hundreds of the alternately-tiered first and second refractive index films is finally formed by spraying and solidifying the refractive index films layer upon layer. By the method and the device, the preparation technology of the reflective polarizing film can be simplified, and production efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of preparation of reflective polarizing films, in particular to a method and device for preparing reflective polarizing films based on 3D printing. Background technique [0002] At present, Brightness Enhancement Film (BEF) is widely used in light-emitting modules to gather the light emitted by the light source, especially on display devices such as monitors. Brightness Enhancement Films are often used to increase display brightness and reduce display energy consumption. . [0003] BEF is divided into prism-shaped BEF and reflective polarizing film. [0004] see figure 1 , is a schematic diagram of a known prism-shaped BEF used in a backlight module of a liquid crystal display. As shown in the figure, the prism-shaped BEF structure 1a includes: a main body portion 10a and a plurality of prism structures 11a. The plurality of prism structures 11a are all in the shape of triangular prisms, and are regularl...
