Abstract
A light source apparatus includes light-emitting blocks, a local dimming control part and a light source driving part driving. The light-emitting blocks include a first-color light source which emits first-color light and a second-color light source which emits second-color light. The second-color light source includes a third-color chip and a fourth-color phosphor disposed on the third-color chip, and is disposed as one package to emit the second-color light therefrom. The local dimming control part compensates a driving current of the first-color light source and a driving current of the second-color light source of each of the light-emitting blocks. The light source driving part drives the first-color light source and the second-color light sources based on the driving current of the first-color light source and the a driving current of the second-color light source, respectively, each compensated by the local dimming control part.
