ABSTRACT:
A display device having a switching mode power supply which operates in boosting mode, said switching mode power supply includes a pulse width modulation circuit for outputting a switching control signal; an initial driver for providing a predetermined current for driving pulse width modulation circuit initially; a switching device for switching according to the signal from said pulse width modulation circuit; a switching transformer for transporting a voltage to second winding coil according to the status of said switching device; a feedback portion for dividing the voltage output from said switching transformer, and for feeding back divided voltage to said pulse width modulation circuit; an output portion for providing a high voltage induced by said switching transformer; and an over voltage stabilizing circuit, located between said feedback portion and said output portion, for compensating for the change of output voltage at an initial driving and at a load change.
