摘要： A system includes a light source, a driving module and a processing unit. The light source includes a red, green and blue light emitting diodes. The driving module is electrically coupled to the red, green and blue light emitting diodes. The driving module is for controlling a driving current outputted to each of the red, green and blue light emitting diodes. The processing unit is communicatively coupled to the driving module. The processing unit receives a video signal containing display information which is inputted into a display screen and is to be displayed thereon. The processing unit analyzes the video signal and determines color temperature of the display information, and outputs a first controlling signal to the driving module for synchronously adjusting the color temperature of the light emitted from the light source to be substantially equal to that of the display information displayed on the display screen.
