ABSTRACT:
An apparatus to genearate a high-voltage regulation signal to control regulation of a display, including: a pulse generator to generate a pulse; a reference signal generator to generate a reference signal with a desired duty ratio using the pulse generated from the pulse generator; and a high-voltage signal generator to generate a switching signal with a duty ratio controlled by the reference signal, according to the pulse from the pulse generator and a feedback regulation output voltage, and to generate a high-voltage regulation signal according to the switching signal, wherein the feedback regulation output voltage is based upon the high-voltage regulation signal.
