Abstract: 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.

Abstract: A light source portion for a liquid crystal display (LCD) device may prevent reduction of the life span of the multiple lamps (LPs) when a surrounding temperature of the multiple LPs is less than a predetermined temperature of the LCD device. The LCD device comprises first and second brightness control portions receiving a brightness control signal, a temperature sensor, a signal output portion connected to the first and second brightness control portions and the temperature sensor, and an inverter portion turning on or turning off the multiple LPs based on the control signal from the signal output portion. When the temperature sensed by the temperature sensor is less than the predetermined temperature of the LCD device, the signal output portion switches the brightness control signal from a high level to a low level, and makes the multiple LPs maintain the high level until the surrounding temperature becomes more than the predetermined temperature.
