BACKLIGHT DRIVING APPARATUS AND DRIVING METHOD THEREOF |
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.
