Abstract: The present invention discloses a backlight module and a liquid crystal device (LCD). The backlight module includes a LED component, a light guiding plate, a quantum dot (QD) layer, and a graphite sheet. The QD layer is arranged between the LED component and the light guiding plate, and the QD layer is arranged on the graphite sheet. By configuring the QD layer on the graphite sheet, the QD layer is prevented from being failed due to high temperature so as to extend the life cycle of the QD layer. Thus, the display performance may be enhanced.

Abstract: A quantum dot backlight module is disclosed. The quantum dot backlight module comprises a light source; a quantum dot layer, which emits fluorescence after being excited by light that is emitted by the light source; and a light guide plate, which guides the fluorescence that is emitted by the quantum dot layer to a needed direction, wherein the quantum dot layer is arranged on a light-entering side of the light guide plate, and a colloid layer is arranged between the light source and the quantum dot layer so as to enable the light source and the quantum dot layer to be bonded with each other closely, whereby the light source, the quantum dot layer, and the light guide plate are assembled together. According to the present disclosure, the light transmission mode of the light source after entering into the light guide plate is changed through changing the structure of the quantum dot backlight module, so that the light loss thereof can be reduced, and the light-emitting efficiency of the backlight module can be improved.
