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.

Abstract: A LCD and the display method thereof are disclosed. The LCD includes a light guiding plate, a light source, a QD media layer, a first polarizer, and an advanced polarization conversion film (APCF). The QD media layer is arranged between the light source and the first polarizer, the first polarizer and the APCF are arranged between the QD media layer and the light guiding plate. The light beams emitted from the light source pass through the QD media layer and activate the QD media layer to emit lights In this way, the brightness of the reflective LCD may be enhanced.
