PURPOSE: A power saving system is provided to adjust power voltage supplying in each circuit by rendering an image displaying unit to receive a power saving signal from a computer by wireless. CONSTITUTION: A computer(10) comprises the first control unit creating a control signal by power saving modes and a wireless converting unit(12) converting the control signal according to power saving modes inputted from the first control unit(11) into a wireless signal and transmits the wireless signal. An image displaying unit(20) comprises a wireless demodulation unit(21), a power source unit(22), the second control unit(23) and a circuit breaking unit(24). The wireless demodulation unit(21) demodulates the wireless signal received from the wireless converting unit(12) into a control signal according to power saving modes. The power source unit(22) adjusts a magnitude of outputting power voltage in accordance with the control signal inputted from the wireless demodulation unit(21) and supplies the outputting power voltage to each circuits. The second control unit(23) controls each circuit by operating the power voltage supplied from the power source unit(22). The circuit breaking unit(24) intercepts the operation of the second control unit(23) if a control signal of a specific saving mode is inputted from the wireless demodulation unit(21). In addition, the circuit breaking unit(24) re-drives the operation of the second control unit(23) if a control signal of a saving mode except the specific saving mode is inputted.
