发明名称 LED driving circuit for back light and driving method thereof and back light driving apparatus
摘要 A circuit and method for driving a light emitting diode for a backlight, and a backlight driving apparatus using the same is provided. A circuit for driving a light emitting diode (LED) for a backlight includes a filtering unit configured to receive a pulse width modulation (PWM) signal and remove noise of a predetermined band, a duty stabilization unit configured to stabilize a duty of a PWM signal filtered by the filtering unit, a dimming signal generation unit configured to generate a dimming signal based on a PWM signal stabilized by the duty stabilization unit, and an LED driving unit configured to drive the LED for the backlight based on the dimming signal generated by the dimming signal generation unit.
