Problems solved by technology

[0004] However, with the improvement of people's lives, the thinning requirements of LCD TVs are getting higher and higher. In the prior art, the method of reducing the thickness of the backlight module by using the lens lamp method can only reduce the light mixing distance to about 15mm at most, so it cannot Meet the ultra-thin demand of LCD TV

Abstract

The invention provides a backlight module set and a display device. The backlight module set comprises an LED lamp, a reflection plate, a light guide layer and a diffusion plate, wherein the reflection plate is arranged on one side of the LED lamp; the other side of the LED lamp is orderly provided with the light guide layer and the diffusion plate; the light guide layer is arranged between the light guide layer and the diffusion plate; and lattice points capable of reflecting light rays are arranged on a connection surface between the diffusion plate and the light guide layer, and the bottom surface of the light guide layer and facing the LED lamp. Mixed spectrum distance of the direct backlight module set can be reduced and a super-thinning display device can be achieved.

Description

technical field [0001] The invention relates to display technology, in particular to a backlight module and a display device. Background technique [0002] At present, with the development of electronic technology and the improvement of consumers' requirements for TV size and picture quality, LCD TV has become the focus of development in the industry. [0003] The backlight module in LCD TV is an important component that provides light source for LCD panel. According to the incident position of the backlight light source, the backlight module can generally be divided into two types: direct type and edge type. Among them, the direct-type backlight module has advantages in the area control of the backlight, and is suitable for larger-sized LCD screens. However, due to the structural characteristics of the direct-type backlight module, it is necessary to leave a sufficient light mixing distance between the light source and the film material, otherwise, spots and other phenome...
