  • BACKLIGHT ASSEMBLY AND DISPLAY DEVICE HAVING THE SAME
    Publication number: 20090091265
    Abstract: 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.

    Abstract: A backlight assembly includes a plurality of line light source sections and a light source driving section. The line light source sections include a plurality of point light sources disposed along a first direction, and are disposed along a second direction substantially perpendicular to the first direction. The light source driving section controls each of the line light source sections to individually drive the point light sources. The light source driving section controls the line light source sections so that at least one of the line light source sections is sequentially driven along the second direction. Thus, the point light sources are individually activated within a required area, and are sequentially activated by at least every one line along the second direction, so that power consumption for driving the backlight assembly may be decreased.
