Claim Text:
1. A method of dimming a light source module, comprising: generating a first group of first to k-th driving signals and a second group of first to m-th driving signals, based on an image signal; driving first to k-th light source blocks of a first light emitting module using the first group of first to k-th driving signals during a first period of a reference period, and driving first to m-th light source blocks of a second light emitting module using the second group of first to m-th driving signals during a second period of the reference period; and determining the duration of the first period and the duration of the second period using a luminance ratio between a first partial image displayed on a portion of a display panel adjacent to the first light emitting module and a second partial image, which is different from the first partial image, displayed on a portion of the display panel adjacent to the second light emitting module, wherein the light source module comprises a light guide plate, the first light emitting module disposed at a first edge of the light guide plate, and the second light emitting module disposed at a second edge of the light guide plate being disposed substantially opposite to the first edge of the light guide plate, wherein k and m are natural numbers, and wherein a first selecting signal turns on a first switching element connected to the first light emitting module at the start point of the first period which is the start point of the reference period, and turns off the first switching element before the end point of the first period, and a second selecting signal turns on a second switching element connected to the second light emitting module at the start point of the second period which is the end point of the first period and turns off the second switching element before the end point of the second period which is the end point of the reference period.
