Embodiment 1

[0026] The invention provides a method for making an optical film. Ultraviolet light is irradiated through a base material with a microstructure or a pattern to an ultraviolet curable resin that has not yet been formed or is being formed into a prism structure, so as to obtain the surface of the formed prism structure. An optical film with a corresponding microstructure or pattern formed on it. The main principle of this scheme is: irradiate ultraviolet light through the base material with microstructure or pattern on the UV curable resin of the prism structure to be formed, so that the corresponding microstructure or pattern is formed on the surface of the formed prism structure. 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, increasing the brightening effect of the ...

Embodiment 2

[0037] 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.

[0038] 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 substrate corresponding to the microstructure or pattern is formed by irradiating the ultraviolet resin of the prism layer to be formed. That is, in this embodiment, microstructures or patterns of various shapes are formed on the surface of the prism layer of the ...

Embodiment 3

[0044] In this embodiment, for the sake of clarity, the substrate with microstructure or pattern is defined as the second substrate, and the substrate used to make the optical film is the first substrate; the first optical film provided in this embodiment The film production equipment includes: a first optical film production device, the first optical film production device is used to apply prism resin on the optical surface of the first substrate, and at the same time transmit ultraviolet light through the surface with a microstructure or The patterned second substrate irradiates the prism resin of the first substrate to obtain an optical film with a corresponding microstructure or pattern on its surface. The principle of this scheme is mainly to irradiate ultraviolet light on the prism resin surface of another substrate through a substrate with a microstructure or pattern. , so that the difference in light intensity causes a corresponding microstructure or pattern to be form...

Abstract

The invention provides an optical film manufacturing method and an optical film. The optical film manufacturing method comprises the steps that ultra-violet irradiates ultra-violet cured resin which does not form or is forming a prism structure through a base with a microstructure or pattern, and the optical film which forms a corresponding microstructure or pattern on the surface of the 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 resin to be molded into the prism structure. 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 for making an optical film and the 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 t...
