Patent ID: 6948081

Claim:
A power saving apparatus in a power control system of a monitor, the power saving apparatus comprising: a power supply unit which supplies power to each block of the monitor; a signal sensor which senses a video synchronization signal input into the signal sensor and generates data based on an input state of the video synchronization signal; a signal driver which converts a video signal into a display driving signal; a display which displays the video signal, in response to the display driving signal, on a screen; and a microprocessor which determines whether the monitor is in a power saving mode or a normal mode based on the data generated by the signal sensor, said microprocessor permitting the power to be supplied to said signal sensor, said signal driver and said display when it is determined that the monitor is in the normal mode, said microprocessor cutting off the power supplied from the power supply unit to said signal sensor, said signal driver and said display when it is determined that the monitor is in the power saving mode, said microprocessor permitting power to be resupplied to said signal sensor after a first predetermined time interval during said power saving mode.
