ABSTRACT:
An inverter of a liquid crystal display for receiving a power voltage for burst dimming via one power terminal to simultaneously adjust a burst dimming and an analog dimming is disclosed. In the inverter of the liquid crystal display, a burst dimming signal generator receives a triangular-wave signal and a power voltage for burst dimming to generate a burst dimming signal. An analog dimming voltage generator receives the power voltage for burst dimming to generate an analog dimming voltage. And a main controller receives the burst dimming signal and the analog dimming voltage to generate a pulse width modulating signal which is used for generating a driving current of a backlight assembly.
