    摘要: A backlight assembly includes a light source assembly including a plurality of light source blocks arranged in a first direction, each light source block including a substrate including a reflecting surface and a plurality of point light sources arranged on the substrate, a lower housing accommodating the light source assembly, and a substrate fixing portion disposed at a boundary between adjacent substrates and fixing the light source assembly to the lower housing. The substrate fixing portion includes a head extending overlapping the boundary between the adjacent substrates of the light source blocks and pressing the substrates towards the lower housing, and an engaging protrusion protruding from the head and fixed to the lower housing.

    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.
