Abstract
A circuit for generating a horizontal synchronizing signal of a display includes: a first comparator which is used to compare a luminance signal of a Component Video Connector of the display and a first reference signal to generate a compared signal; a control circuit which is used to generate a first digital controlled signal according to the compared signal; a first digital-to-analog converter which is used to generate the first reference signal according to the first digital controlled signal; a second digital-to-analog converter which is used to generate a second reference signal according to a second digital controlled signal generated by the control circuit, wherein the second digital controlled signal is determined by the first digital controlled signal; and a second comparator which is used to compare the luminance signal and the second reference signal to generate the horizontal synchronizing signal.
