ABSTRACT:
A power saving display device and a method for controlling power thereof. The power saving display device comprises a main power supply circuit for converting an output voltage from a power rectifier into desired voltages to be supplied to components in the display device, a synchronous signal discriminator for discriminating whether horizontal and vertical synchronous signals are inputted and generating first and second control signals for power management in accordance with the discriminated result, a main power interrupter for interrupting the operation of the main power supply circuit in response to the first control signal from the synchronous signal discriminator, an auxiliary power supply circuit being continuously operated in response to the output voltage from the power rectifier although the main power supply circuit is interrupted in operation, a heater power regulation circuit for varying a voltage being supplied to a heater of a cathode ray tube or maintaining it constantly in response to the second control signal from the synchronous signal discriminator, and a heater power connector for supplying an output voltage from the auxiliary power supply circuit to the heater power regulation circuit when the main power supply circuit is interrupted in operation.
