摘要： A backlight driver includes an inverter controller, a dimming signal compensator and an inverter. The inverter controller generates a pulse width modulation signal in response to a control signal and outputs a first dimming signal that represents a duty ratio of the pulse width modulation signal and a second dimming signal that represents an amplitude of the pulse width modulation signal. The dimming signal compensator receives the first and second dimming signals, compares the first dimming signal with a predetermined reference duty ratio and compensates the second dimming signal in accordance with the compared result to generate a third dimming signal. The inverter outputs a driving voltage to drive the backlight and varies a voltage level of the driving voltage in response to the first and third dimming signals to control a brightness of the backlight.

摘要： A flat fluorescent lamp includes a lamp body and first external electrodes. The lamp body has discharge spaces formed therein. The first external electrodes are disposed at a first end portion of an outer surface of the lamp body and a second end portion that is opposite to the first end portion to define a first region where the discharge spaces overlap the first external electrodes and a second region where the discharge spaces do not overlap the first external electrodes. Each of the discharge spaces has a first width at the first region and a second width that is smaller than the first width at the second region. Therefore, an overlapping region between the first external electrodes and the discharge space increases to lower the discharge voltage.

摘要： A planar light source device includes a body, a plurality of partition members, and first and second electrodes. The body includes a discharge space. The partition member divides the discharge space into a plurality of discharge regions. The first electrodes are disposed at the edge portions of the body, and a discharge voltage is applied to the first electrodes. The second electrode is disposed between the partition members. Therefore, the second electrode corresponding to the discharge region prevents deflection to enhance optical characteristics of the planar light source device. Furthermore, the second electrode lowers a discharge start time and reduces a discharging time.
