But, when adopting this way, quantum dot diaphragm 13 is complicated to make, and cost is higher, and because the thickness of quantum dot diaphragm 13 is thinner, the phenomenon of diaphragm rupture easily occurs when its length is longer

Abstract

The invention discloses a backlight module, which comprises a light guide plate (110), a light source strip (120) and a plurality of quantum dot films (130); the light guide plate (110) is provided with at least one incident light side face(111); the light source strip (120) is arranged close to the incident light side face(111); the quantum dot films (130) are arranged between the light source strip (120) and the incident light side face(111); the light emitted by the light source strip (120) passes through the quantum dot films (130) to irradiate the incident light side face(111). The invention also discloses a liquid crystal display with the backlight module. Since the short quantum dot films are arranged between the light source and the incident light side face of the light guide plate to replace a long quantum dot film of the prior art and the short quantum dot films are easy to fabricate, are low in cost and cannot easily break, the safety and reliability of the quantum dot films are enhanced. Furthermore, because uniform-chromaticity white light distribution is formed on the incident light side face of the light guide plate, the optical quality of the backlight module is increased.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a backlight module capable of avoiding rupture of a quantum dot film and making the chromaticity of the light-incident side of a light guide plate consistent, and a liquid crystal display with the backlight module. Background technique [0002] With the development of the information society, people's demand for flat panel displays has grown rapidly. A Liquid Crystal Display (LCD for short) has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. Generally, a liquid crystal display includes a liquid crystal display panel and a backlight module disposed opposite to each other. Since the liquid crystal display panel cannot emit light by itself, it must use the backlight provided by the backlight module to display images. [0003] In an existing backlight mod...
