ABSTRACT:
A picture tilt complementing circuit in a display device includes: a microcomputer for receiving horizontal and vertical sync signals from a computer and generating a tilt control signal; a horizontal sawtooth wave generation unit for converting the tilt control signal transmitted from the microcomputer into a sawtooth wave signal according to a horizontal fly back signal; a vertical sawtooth wave generation unit for converting the tilt control signal transmitted from the microcomputer into a sawtooth wave signal according to a vertical fly back signal; a vertical center control unit for synthesizing a horizontal sawtooth wave signal generated by the horizontal sawtooth wave generation unit with a vertical position control signal transmitted from the microcomputer and sending the synthesized result to a vertical output unit; and a horizontal position control unit for synthesizing a vertical sawtooth wave signal generated by the vertical sawtooth wave generation unit with a horizontal position control signal transmitted from the microcomputer and sending the synthesized result to a horizontal oscillation unit.
