    • A display apparatus includes a power supply unit which supplies power to the display apparatus, a secondary battery which is charged from the supplied power, a backlight driving unit which drives a backlight of the display apparatus using at least one of the power of the power supply unit and the power charged in the secondary battery, A control unit controls power supplied to the backlight and a charging operation of the secondary battery based on a predetermined power consumption level. The secondary battery charges when there is power left over, and discharges to brighten the backlight when a power level demanded exceeds the predetermined power consumption level.
    • 显示装置包括向显示装置供电的电源单元,从供电电源充电的二次电池;背光驱动单元,其使用电力供给中的至少一个来驱动显示装置的背光源 单元和二次电池中充电的电力,A控制单元基于预定的功率消耗水平来控制提供给背光的电力和二次电池的充电操作。 当剩余电力时,二次电池充电,当需要功率电平超过预定功耗水平时,放电以使背光变亮。
