An apparatus of driving a light source for a display device is provided. The apparatus includes a temperature sensor ( 940 ) sensing a temperature and generating an output voltage based on the sensed temperature, a buffer ( 950 ) generating an output signal having a state depending on the output voltage of the temperature sensor ( 940 ), an oscillator ( 931 ) generating an oscillating signal having a frequency depending on the state of the output signal of the buffer, and an inverter ( 920 ) performing a switching operation in response to the oscillating signal from the oscillator ( 931 ). Therefore, the inverter ( 920 ) increases the voltage applied to the light source when the temperature near the light source is lower than a predetermined temperature since the frequency of the oscillating signal is increased.
