    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.

    Abstract: A backlighting assembly for an LCD display is divided into a plurality of selective dimming areas each having a respective plurality of light generating blocks. A plurality of driving units supply power to the light generating blocks. The light generating blocks are grouped into light source groups. Each of the driving units supplies power to at least one light generating block in a first light source group and a second light generating block in a second light source group but not to all the light generating blocks in any one light source group. Light generating blocks connected to a same driving unit may be distributedly arranged to be nonadjacent to one another. Plural driving units are used to fully power a brightly lit one dimming area, thereby reducing the loads on the individual driving units and preventing overheating.
