ABSTRACT:
The present invention relates to a device for reducing power consumption of a monitor and the method thereof. The device for reducing power consumption of a monitor according to the present invention comprises a control unit which generates a power-saving mode signal according to the control signal inputted from an external signal source; a first switching unit, connected to said control unit, which turns on or off the power according to said power-saving mode signal, in which said power is supplied from the power-supply terminal to the deflection drive terminal; a second switching unit which turns on or off the power supplied from the power-supply terminal to the heater, in which said switching unit operates in the same manner as the first switching unit; and a voltage-drop unit, connected between said power-supply terminal and said heater, which lowers the voltage applied from said power-supply terminal only when said second switching unit is off, and then supplies the same to said heater. By using a device for reducing power consumption of a monitor and the method thereof according to the present invention, the following effects can be obtained: First, since it operates in a single power-saving mode, it provides a simple construct, which in turn results in enhanced effects in terms of production process and costs. Second, power consumption is reduced to less than 5 W while allowing a fast returning time to normal status.
