Abstract
Disclosed herein are a single-stage backlight inverter and a method for driving the same. The single-stage backlight inverter comprises a main oscillator for generating a predetermined triangle-wave oscillation signal, a predetermined clock signal and an inverted clock signal, and an output drive controller responsive to the triangle-wave oscillation signal, clock signal and inverted clock signal from the main oscillator and first and second reference voltages set therein. The second reference voltage has a level set to an intermediate level of the triangle-wave oscillation signal. The output drive controller is adapted to generate a first drive control signal and generate a second drive control signal. The inverter further comprises a first output unit for outputting a pair of first switching signals in response to the first drive control signal, and a second output unit for outputting a pair of second switching signals in response to the second drive control signal.
