摘要： A surface light source device includes a light source body having an internal space. A partition wall is disposed in the internal space of the light source body to divide the internal space into a plurality of discharge spaces. The partition wall has end portions that make contact with inner surface of the light source body. The partition wall has a throughhole, through which the discharge spaces are connected to each other. The light source body includes a voltage applying part that applies a voltage to the discharge space to generate plasma in the discharge space. A barrier is disposed adjacent to the throughhole to restrict a flow of the plasma generated from a discharge gas through the throughhole. The barrier screens the throughhole to restrict the flow of the plasma through the throughhole. Therefore, uniformity of luminance of the surface light source device is improved.

摘要： A lamp driving apparatus includes a change rate calculating section, a dimming transforming section and a power supplying section. The change rate calculating section calculates a change rate signal from an image signal corresponding to the image. The dimming transforming section outputs a digital dimming signal and an analog dimming signal, in response to a dimming signal provided from an external device and the change rate signal. The power supplying section provides the lamp with power, in response to a vertical synchronizing signal, the analog dimming signal and the digital dimming signal. Thus, although an instantaneous lamp current is increased, life and characteristics of the lamp will not be adversely influenced, and motion blur of a moving image may be removed.

摘要： A backlight assembly device includes lamps, an inverter, a sensing unit, a normal lighting determiner and an inverter controller. The inverter applies a control signal to the lamps to control operation of the lamps. The sensing unit outputs sensing voltages in response to currents flowing in the lamps. The normal lighting determiner compares the sensing voltages to a reference voltage for determining an operating state of the lamps to output a determination signal and varies the reference voltage in response to a change in the operating state of the lamps. The inverter controller outputs the control signal in response to the determination signal.
