摘要： An optical member according to one or more embodiments includes an optical plate and an optical film. In an embodiment, the optical plate includes an incident part receiving light provided from the exterior and an emitting part emitting the light. The optical film is attached to the incident part and includes a first conductive layer, a second conductive layer facing the first conductive layer and polarized particles disposed between the first conductive layer and the second conductive layer. Thus, light sources of a backlight assembly may be individually driven regardless of the type of light source and the disposition of the light sources, and image display quality may be improved by improving a contrast ratio by realizing various gradation voltages.

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： In a method for driving a light source, a backlight assembly for performing the method and a display apparatus having the backlight assembly, a light source is driven by an initial power until a first time when initial brightness of the light source decreases to a reference brightness. Then, the light source is driven by a first compensation power after the first time, so that the light source has first compensation brightness. When the brightness of the light source decreases to the reference brightness, a driving power applied to the light source is changed to compensate the brightness of the light source. Thus, the light source is driven to have uniform brightness over an extended length of time.
