Method of driving a light source, light source apparatus for performing the method and display apparatus having the light source apparatus

摘要

A method of driving a light source includes; driving a plurality of light source strings in response to a plurality of driving signals, when a light source module having the plurality of light source strings connected in parallel with each other receives a driving voltage, detecting a detection voltage from channel input terminals of a multichannel current control part, wherein the multichannel current control part controls a resistance difference of the plurality of light source strings based on the plurality of driving signals, and controlling a level of the driving voltage via adjusting a current applied to a feedback terminal of a driving voltage generating part, wherein the driving voltage generating part generates the driving voltage.
