Abstract
A backlight module includes a back plate, a diffuser opposite to the back plate, a plurality of dot light sources arranged on a surface of the backplate facing toward the diffuser in a matrix, thermal emitters configured between the dot light sources, and an optical film configured on the surface of the diffuser facing away the backplate. In addition, the present disclosure also relates to a liquid crystal panel and a liquid crystal device (LCD). The backlight module radiates infrared rays toward the liquid crystal panel, and the liquid crystal within the liquid crystal panel may convert the infrared rays into heat. That is, the absorbed rays may be converted into thermal energy heating up the liquid crystal panel. Thus, even at a low temperature, the LCD may function normally.
