Abstract
A backlight assembly includes a switching section for switching on/off an input voltage so as to output a primary voltage in accordance with a control signal; and a voltage boosting section for boosting the primary voltage received at a primary side thereof to a secondary voltage at a secondary side thereof. The primary and secondary sides of the voltage boosting section are electrically isolated from each other. In a feedback link for supplying the control signal from the secondary side to the primary side, a signal isolation section is provided for both transmitting the control signal between and electrically isolating primary side and secondary side portions of the feedback link. Additionally or alternatively, a balancing circuit section is connected between the secondary side of the voltage boosting section and a plurality of lamps so as to uniformly supply an alternating current, generated by the secondary voltage, to the lamps, in order to uniformize the luminances of the lamps.
