Filed: 2002-11-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power source controller for display which can make power consumption in a power saving mode zero or very small as compared with that in the conventional power saving mode.  <P>SOLUTION: When RGB signals do not change for a fixed period of time and a computer 7 turns a power source control signal 9A off, an input control part 6 makes a display control part 4 erase the display of a display part. When a power source control part 2 stops power source supply to an input control part and the display control part and turns a power source control signal 9B off, the computer interrupts the supply of AC power source 6 to a power source part by turning a power source control signal 9C off and by opening an AC switch 11. As a result, power consumption becomes zero. In turn, when variation appears in the RGB signals, the power source control signal 9C is turned on and the AC switch conducts and the power source control part is activated and power source is supplied to the display control part and the input control part. When the power source control part turns the power source control signal 9B on, a display signal is sent from the computer and the display of the display part is resumed.  <P>COPYRIGHT: (C)2004,JPO
