A method of driving a light-source module includes adjusting a frequency of a boosting switching signal based on a dimming signal which controls luminance of a light-emitting diode ('LED') string of the light-source module, where the LED string comprises a plurality of LEDs connected to each other in series, and controlling a main transistor in response to the boosting switching signal to transfer a driving voltage to the LED string.

Method of driving light-source with improved contrast ratio and display apparatus for performing the method

A light source apparatus includes a light source which emits light, a response improving part which generates a response improving signal based on a first dimming control signal having a first rising period, a first operation part which generate a second dimming control signal which has the first rising period based on the first dimming control signal, a second operation part which generates a third dimming control signal by performing an arithmetic operation based on the second dimming control signal and the response improving signal, the third dimming control signal having a second rising period shorter than the first rising period and a light source driver which generates a light source driving signal based on the third dimming control signal to drive the light source based on the light source driving signal.
