Abstract
A light source apparatus includes a light source disposed adjacent to a side portion of a light guide plate and a light source driver driving the light source. The light source driver includes a booster and a protecting circuit. The booster boosts an input voltage to a driving voltage for driving the light source. The protecting circuit selectively cuts off the input voltage applied to the booster according to an output current of the booster, reducing the risk of damage to the driver due to shorts, overcurrents, or the like.
