Abstract
One or more embodiments of the present disclosure provide a method for driving light sources, a device for driving light sources and a display device having the device for driving the light sources. Power information is read based on position information on the light sources to output a light source control signal transmitting the power information. The power information determines a level of power applied to each of the light sources. Externally provided input power is changed into a plurality of driving powers having a level changed based on the light source control signal. The driving powers are applied to the light sources, respectively. According to one aspect of the present disclosure, uniformity of luminance distribution of a display panel may be improved.
