    摘要： A backlight assembly a plurality of first light-emitting chips for emitting light and a thermistor for indicating the temperature of the first light-emitting chips. The first light-emitting chips emit first color light and are connected in series to each other. The thermistor may be connected in series to the first light-emitting chips and has an electrical resistance that decreases with an increase of its temperature. The light amount emitted by the first light-emitting chips is controlled by pulse width modulating the current driving the first light-emitting chips based on the temperature (resistance) of the thermistor and based on received image data. Thus, a decrease in brightness due to temperature variation may be compensated for while performing color dimming.

    摘要： A backlighting assembly for an LCD display is divided into a plurality of selective dimming areas each having a respective plurality of light generating blocks. A plurality of driving units supply power to the light generating blocks. The light generating blocks are grouped into light source groups. Each of the driving units supplies power to at least one light generating block in a first light source group and a second light generating block in a second light source group but not to all the light generating blocks in any one light source group. Light generating blocks connected to a same driving unit may be distributedly arranged to be nonadjacent to one another. Plural driving units are used to fully power a brightly lit one dimming area, thereby reducing the loads on the individual driving units and preventing overheating.
