ABSTRACT:
A light source driving apparatus according to the present invention includes a controller, a first driver and a second driver. The controller outputs a first control signal to drive the light source in a normal-luminance mode and outputs a second control signal to drive the light source in a low-luminance mode. The first driver drives the light source, based on a first voltage in response to the first control signal in the low-luminance mode. The second driver drives the light source, based on a second voltage in response to the second control signal in the normal luminance mode. Therefore, the light source driving apparatus driving the light source decreases current-consumption and prevents unnecessary power consumption from increasing in a low-luminance driving mode.
