| (54) | System and method for reducing the cost of electricity consumption in a display device |
| (57) A method and system for reducing the cost of electricity consumption in a display
device by controlling the illuminance of at least one light source of said display
device with respect to the electricity consumption rate information for different
time periods is described. The said system comprises; a power consumption status detector
for generating the usage status information for the usage time of the display device
by detecting the power consumption information for the usage time of said display
device; an illuminance controller for controlling the illuminance of at least one
light source of said display device with respect to the usage status information,
characterized in that; said power consumption information contains electricity consumption rate information
for different time periods. The said method comprises the steps of; detecting the
usage time of the display device; detecting the power consumption information for
the usage time of said display device; generating the usage status information with
respect to said power consumption information; controlling the illuminance of at least
one light source of said display device with respect to said usage status information,
characterized in that; said power consumption information contains electricity consumption rate information
for different time periods.
