Abstract
A backlight assembly includes a light source, a receiving container, a temperature sensing module and a power source controlling circuit. The light source produces light. The receiving container includes a bottom plate and sidewalls upwardly extending from edge portions of the bottom plate to receive the light source. The bottom plate defines an aperture. The temperature sensing module is disposed at the aperture of the receiving container. The temperature sensing module senses a light source temperature. The power source controlling circuit controls a light source driving voltage according to the temperature of the light source. Therefore, a time for stabilizing the luminance and a power consumption may be reduced.
