摘要： A device of driving a light source for a display device is provided, which includes: a temperature sensor detecting a temperature near the light source; and an inverter controlling the light source depending on temperature information supplied from the temperature sensor. The inverter adjusts either or both of a driving frequency and a driving current of the light source depending on the temperature information. The inverter decreases the driving frequency when the detected temperature is lower than a first temperature, and the inverter increases the driving current when the detected temperature is lower than a second temperature lower than the first temperature.
