Embodiment 1

[0028] The invention provides a method for making an optical film. By irradiating ultraviolet light through a substrate with microstructures or patterns on the surface to the ultraviolet light curing glue on the surface of the prism structure of the optical film, the surface formed on the surface of the prism structure is obtained. The corresponding microstructure or pattern of the optical film. The main principle of this scheme is: irradiate the ultraviolet light curing adhesive on the surface of the optical film through the substrate with a microstructure or pattern on the surface, so that the surface of the corresponding microstructure or pattern is formed on the surface of the ultraviolet light curing adhesive. The intensity of ultraviolet light behind the surface of the substrate with microstructure or pattern changes with the structure of its microstructure or pattern, so that the corresponding microstructure or pattern is formed on the surface of the optical film, increa...

Embodiment 2

[0045] This solution also provides an optical film, and the optical film is an optical film obtained by the method for manufacturing an optical film as described in any one of the above embodiments.

[0046] Specifically, the optical film includes a base material and a prism layer, the base material includes a first optical surface and a second optical surface positioned on the first optical surface, and the prism layer is arranged on the first optical surface of the base material. On the optical surface; on the surface opposite to the first optical surface in the prism layer, a microstructure or pattern that can adjust the light-gathering effect of the prism layer is arranged; the microstructure or pattern has a The corresponding microstructure or pattern of the substrate is formed by irradiating the prism layer of the optical film. That is, in this embodiment, microstructures or patterns of various shapes are formed on the surface of the prism layer of the optical film, and ...

Embodiment 3

[0052] In this embodiment, for the sake of clarity, the substrate with a microstructure or pattern on the surface is defined as the second substrate, and the substrate of the optical film is defined as the first substrate; mode, there are two types of optical film production equipment, in this embodiment, the two optical film production equipment are respectively the first optical film production equipment and the second optical film production equipment; the first optical film production equipment includes : The first optical film production device, the first optical film production device is used to coat the prism resin on the optical surface of the first substrate, and at the same time transmit the ultraviolet light through the second substrate with microstructure or pattern on the surface The material is irradiated to the prism resin of the first substrate to obtain an optical film having a corresponding microstructure or pattern on the surface. The principle of this schem...

Abstract

The invention provides an optical film manufacturing method and a manufacturing device. The optical film manufacturing method comprises the steps that prism resin gumming is carried out on the optical face of a first base, and prism resin is transferred to a soft film forming roll; ultra-violet irradiates the prism resin of the first base through a second base with a microstructure or pattern; and an optical film which forms a corresponding microstructure or pattern on the surface of a formed prism structure is acquired. The problems of high cost and complicated process of the existing optical film manufacturing method are solved. The operation is simple. Ultra-violet and the corresponding base irradiate the position of the prism of the optical film. The brightening effect of the optical film is ensured. The production cost is low. Defects are avoided in a preparation process. The production efficiency is high.

Description

technical field [0001] The invention relates to the field of making backlight film materials, in particular to a method and equipment for making an optical film. Background technique [0002] At present, optical films have been widely used in the fields of optics and optoelectronics technology to manufacture various optical instruments. It is especially widely used in the field of backlight modules. For example, the brightness enhancement film in the backlight module can be used to gather the light emitted by the light source. Especially in display devices such as liquid crystal displays, the brightness enhancement film is often used to increase display brightness and save energy. Displays the energy of the battery device. [0003] The traditional production method of brightness enhancement film is carried out through hard mold and soft film technology. The structure of brightness enhancement film is initially processed by precision machining diamond cutter head on the mirr...
