Abstract
A method of driving a light source, a light source apparatus for performing the method, and a display apparatus having the light source apparatus are disclosed in accordance with one or more embodiments. In the method, a plurality of light source strings connected in parallel is driven by applying a driving voltage to a first terminal of the light source strings. A peak current due to a voltage deviation of each of the light source strings is switch-controlled to uniform an average current of the light source strings. Thus, a peak current flowing through light source strings in accordance with a voltage deviation of the light source strings is switch-controlled, so that an average current of the light source strings may be uniformly maintained. Therefore, a voltage deviation is not consumed as power, so that damage to circuit elements due to heat may be prevented.
