Abstract:
1. A device for reducing power consumption of a monitor, the monitor comprising a power supply terminal coupled to a deflection drive terminal and a heater, comprising: a control unit configured to generate a power-saving mode signal in response to a control signal inputted from an external signal source; a first switching unit, coupled to the control unit, configured to turn on or off the power supplied from the power-supply terminal to the deflection drive terminal in response to the power-saving mode signal; a second switching unit coupled to the control unit, configured to turn on or off the power supplied from the power-supply terminal to the heater, in response to the power-saving mode signal; and a voltage-drop unit, coupled to the power-supply terminal and the heater, configured to lower the voltage applied from the power-supply terminal to the heater when the second switching unit is off; wherein the first switching unit comprises a first transistor, comprising: a third base coupled to the first collector of the first transistor via a third resistor a diode; a third emitter coupled to the power supply terminal and coupled to the third base via a forth resistor; and a third collector coupled to the heater.
