    摘要: A backlight driving apparatus and a driving method thereof, in which the backlight driving apparatus includes a driving unit and a controller. The driving unit boosts an input voltage in response to a duty ratio of a control signal and provides the boosted input voltage to an LED array. The controller increases the duty ratio of the control signal in a step-by-step fashion by comparing a preset target value with a sequentially increasing step-setting value if a driving start signal is enabled.

    摘要: A power supply apparatus includes a storage battery, a power part and a solar battery part. The storage battery provides a charged voltage to an electronic device. The power part provides an external voltage to the electronic device and simultaneously charges the storage battery, upon determining that the external voltage is provided to the power supply apparatus. The solar battery part charges the storage battery using a voltage output by a solar battery upon determining that the external voltage is not provided to the power supply apparatus and the electronic device is not in use, and provides the voltage output by the solar battery and the charged voltage output by the storage battery to the electronic device, upon determining that the external voltage is not provided to the power supply apparatus and the electronic device is in use.
