Abstract
A display apparatus includes a power supply device. The power supply device includes a power supply part and an integrated circuit chip. The power supply part outputs a first power to drive a backlight and a second power to drive a main circuit. The integrated circuit chip increases, based on a control signal to adjust a brightness of the backlight being received, a current value of the second power, and reduces, based on the control signal not being received for a first threshold time, the current value of the second power.
Claims20
A display apparatus comprising a power supply device, the power supply device comprising:
- a power supply part configured to output a first power to drive a backlight and a second power to drive a main circuit;
- and
- an integrated circuit (IC) chip configured to increase, based on a control signal to adjust a brightness of the backlight being received, a current value of the second power, and reduce, based on the control signal not being received for a first threshold time, the current value of the second power.
A control method of a display apparatus, the method comprising:
- outputting, by a power supply part, a first power to drive a backlight and a second power to drive a main circuit;
- and
- increasing, by an integrated circuit (IC) chip, a current value of the second power based on a control signal to adjust a brightness of the backlight, and reducing, based on the control signal not being received for a first threshold time, the current value of the second power.
A display apparatus comprising a power supply device, the power supply device comprising:
- a power supply part configured to output a first power to drive a backlight and a second power to drive a main circuit;
- and
- an integrated circuit (IC) chip configured to change an operation mode of the display apparatus to a low power mode from a normal mode, based on a control signal to adjust a brightness of the backlight not being received for a first threshold time.
