Abstract:
1. An apparatus for reducing power consumption of a backlight lamp in a LCD (Liquid Crystal Display), comprising: a power unit configured to supply power; a control unit configured to receive power supplied from the power unit and output a brightness control information signal; an inverter unit configured to receive the brightness control information signal from the control unit and output driving power for driving a backlight lamp; and a backlight lamp configured to receive the power from the inverter unit, wherein when the LCD is turned on or a wake up operation is activated after a suspend mode, the control unit is configured to control the brightness adjustment information signal so as to be related to a brightness increase curve of the backlight lamp such that power supplied to the backlight lamp is gradually increased over time, and wherein the brightness control information signal output by the control unit comprises one of a plurality of discrete incremental level values corresponding to discrete brightness levels, and the inverter unit outputs power to the backlight lamp at a level corresponding to the required brightness level.
