摘要： PURPOSE: A display device and a power supplying method thereof are provided to implement a bright screen by increasing the output impedance of a secondary battery and constantly controlling the output impedance of a power supply unit. CONSTITUTION: A power supply unit(110) supplies power to a display device. A secondary battery(120) is charged with the supplied power. A backlight driving unit(130) drives a backlight of the display device by using the power of the power supply unit or the power of the secondary battery. A control unit(140) controls the charging operation of the secondary battery and the power supplied to the backlight based on preset power consumption. [Reference numerals] (110) Power supply unit; (120) Secondary battery; (130) Backlight driving unit; (140) Control unit
