Light source driving apparatus, display device having the same, and driving method thereof

摘要

A light source driving apparatus (100) for time-dividing and driving a plurality of light sources, a display device having the same, and a driving method thereof are provided. The light source driving apparatus (100) includes a light source module (120) including a plurality of light sources; a light source driver (160) which outputs a driving current to drive the light sources; and a switch (140) which selectively feeds the driving current to the light sources respectively and sequentially drives the plurality of the light sources. The light source driver (160) outputs a low-level driving current to drive the light sources, and thus the driving speed, the system efficiency and the optical power can be increased and the manufacturing cost can be reduced.
