ABSTRACT:
The present invention relates to a power controlling system for a display. When Display Power Management signals, i.e., DPMF/DPMS signals, output from Micom, the controller, are all “Low” and “Low”, a main power switch is turned off. Therefore, power is not supplied to a secondary side of a main transformer and only the Micom is provided with power. As a result, the display enters to a power off mode, wherein power consumption is less than 1 Watt.
