Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0025] In addition, in t...

Abstract

The invention provides an optical composite film, a backlight and a liquid crystal display module. The optical composite film comprises a microprism diffusion film and a brightness enhancement prism film which are bonded together, and the microprism diffusion film and the brightness enhancement prism film are respectively arranged on the light incident surface and the light exiting surface; the microprism diffusion film comprises a first light transmissive substrate and a microprism diffusion structure, the microprism diffusion structure comprises light transmissive spherical particles on thefirst light transmissive substrate facing away from the light incident surface, and the light transmissive spherical particles are regularly and orderly arranged on the first light transmissive substrate. According to the optical composite film, the microprism diffusion film is close to the light exiting surface of a light guide plate, the light from the light guide plate is firstly atomized by the microprism diffusion film, the microscopic convergence of the light guide plate or dots on the light is reduced, the shielding property is improved, and interference fringes between the light guideplate and an LCD panel can be reduced.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical composite film, a backlight source and a liquid crystal display module. Background technique [0002] As people's requirements for the visual effects of monitors and TVs are getting higher and higher, various manufacturers continue to introduce large-size TVs and display screens, such as 42, 45, and 49-inch LCD TVs are very popular, and 70-inch and even 100-inch LCD TVs are very popular. There are also manufacturers of TVs. For making the screen bigger, there are two important technical difficulties. One is to make the panel bigger, and the other is to make the backlight bigger. In particular, the screen panel itself is mainly made of glass, and the substrate needs to be filled with liquid crystal molecules, so The production process is relatively complicated. Currently, some panel factories can only mass-produce panels with a maximum size of about 70 inches. [0003] A liquid ...
