Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] A liquid crystal display device (English: Liquid Crystal Display; abbreviation: LCD) includes a liquid crystal display panel and a backlight module (English: Back Light) arranged on the back of the liquid crystal display panel. type backlight module.

[0043] Among them, the side-type backlight module usually includes structures such as a light source, a light guide plate, a reflection sheet, and an optical film. However, since the optical film of the backlight module includes a variety of film structures, and the material of the film structure is usually relatively soft, the film layers are easy to absorb, and the light is easy to produce after passing through the film structure after mutual adsorption. Optical effects such as...

Abstract

The invention discloses a light guide structure, a manufacturing method thereof, a backlight module and a liquid crystal display device, which belong to the field of making of display panels. The light guide structure comprises a first light guide plate and a second light guide plate which are arranged in a laminated mode, wherein the first surface of the first light guide plate is provided with alight gathering layer; and a diffusion part is arranged between the second surface and the second light guide plate. As the light gathering layer arranged on the first light guide plate can be used for replacing an upper prism and a lower prism in a related technology, the problems of optical effects such as a Newton ring caused by mutual adsorption between film layers can be avoided, and the display quality of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of display panel manufacturing, in particular to a light guide structure and a manufacturing method thereof, a backlight module, and a liquid crystal display device. Background technique [0002] The backlight module is an important part of the liquid crystal display panel, which can provide light sources with uniform distribution and sufficient brightness, so that the liquid crystal display panel can display images normally. [0003] At present, the backlight module provided in the related art includes: a light source, a light guide plate, a reflection sheet, and an optical film, wherein the optical film includes a film layer structure such as a diffusion sheet, an upper prism, and a lower prism. The light guide plate and the diffusion sheet can be used to improve the uniformity of the light emitted by the light source, and the upper prism and the lower prism can be used to increase the brightness of the light emitte...
