Embodiment Construction

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

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

[0035] Step S1. Establish a three-dimensional digital model of the prism film and convert it into work instructions for controlling the operation of the 3D printing device, including a first instruction for printing the base layer of the prism film and a second instruction for printing the prism layer of the prism film.

[0036] Step S2. Put the first raw material for printing the base layer into the feeding chamber of the 3D printing device. The first raw material for printing the base layer is PET polyester. Use melting technology to convert the first raw material into a liquid state, and set the melting temperature at 255- 260°C; 3D printing equipment receives and works according to the first instruction, the print head spr...

Abstract

The invention relates to a 3D printing-based prism film preparation method which comprises the following steps: 1, a three-dimensional digital model of a prism film is established and converted to work instructions of 3D printing equipment, and the work instructions contain a first instruction for printing a substrate layer and a second instruction for printing a prism layer; 2, a first raw material for printing the substrate layer is put into a charging cavity and converted to a liquid state; and the 3D printing equipment sprays the first liquid raw material onto a molding area according to the first instruction, the sprayed first raw material is solidified quickly, a print head reciprocates translationally to print and an entity of the substrate layer is formed by piling up the first raw material layer upon layer; and 3, the second raw material for printing the prism layer is put into the charging cavity and converted to a liquid state; and the 3D printing equipment sprays the second liquid raw material onto the molding area according to the second instruction, the sprayed second raw material is solidified quickly to form a single prism column, and the print head continues to print according to a certain regulations so as to form an entity of the prism layer. By the method and the device, the preparation technology of the prism film can be simplified, and production efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of prism film preparation, in particular to a method and device for preparing a prism film 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 regularly arranged on the main body 10a. T...
