ABSTRACT:
Disclosed is a horizontal oscillation circuit for a monitor performing a stable oscillation even at the start input such as a power input or a mode change. The horizontal oscillation circuit for a monitor includes an operation voltage delaying part for delaying a time period for an operating voltage to reach a voltage level and for outputting a delayed operating voltage, and a horizontal oscillator for inputting the voltage corresponding to the operating mode, the horizontal synchronizing signal and the delayed operating voltage and for outputting a stable oscillation voltage corrresponding to the operating mode. With an output of a stable oscillation voltage from the horizontal oscillation circuit, the horizontal output circuit of a monitor can be protected from being damaged by heat and a stable display can be obtained even at the start input such as a power input or a mode change.
