Abstract: A backlight module including a back plate and a light guide plate structure and a light source assembly disposed on the back plate, wherein the light guide plate structure is mainly formed by splicing a plurality of light guide plate blocks, each of the plurality of light guide plate blocks includes a splicing end surface and at least one incident light end surface, and the light source assembly is disposed on at least one incident light end surface of the light guide plate blocks. Additionally, a liquid crystal display including the above backlight module is disclosed. The light guide plate structure in the backlight module may reduce a light mixing height of the backlight module and is advantageous to thinning the product; in addition, the structure of the light guide plate is simple and easy to be implemented, which is advantageous to lower the cost of the product.

Abstract: A backlight module is disclosed, which comprises a light guide plate having at least one incident light side; a light bar, adjacent to the incident light side; a plurality of quantum dot films, the quantum dot films are arranged between the light bar and the incident light side; wherein the light from the light bar goes through the quantum dot film and irradiates on the incident light side. A LCD device with the backlight module is further disclosed. A plurality of shorter quantum dot films are arranged between the light source and the incident light side of the light guide to replace one longer quantum dot film of the conventional art. And the manufacturing process of the short quantum dot film is simple with low cost, and the film does not have the rupturing issue to improve the safety and reliability of the quantum dot film.
