Patent ID: 8154669

Claim:
A system for illuminating portions of a background wall around a periphery of a display screen; the system comprising: a light source comprising a red light emitting diode, a green light emitting diode and a blue light emitting diode, the light source configured for emitting light from the red, green and blue light emitting diodes to illuminate portions of the background wall around a periphery of the display screen; a driving module electrically coupled to the red, green and blue light emitting diodes, the driving module configured for controlling a driving current outputted to each of the red, green and blue light emitting diodes thereby adjusting color temperature of the light emitted from the light source; a processing unit communicatively coupled to the driving module, the processing unit configured for receiving a video signal containing display information which is inputted into the display screen and is to be displayed thereon, the processing unit configured for analyzing the video signal and determining color temperature of the display information displayed on the display screen, and outputting 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, the processing unit being configured for receiving an audio signal containing sound information, the driving module being configured for controlling flickering frequency of the red, green and blue light emitting diodes, and the processing unit being configured for analyzing the audio signal, determining the sound intensity of the sound information and outputting a second controlling signal to the driving module for synchronously adjusting the flickering frequency of the red, green and blue light emitting diodes according to the sound intensity of the sound information; and a memory device for storing the mapping between the sound intensity of the sound information and the flicking frequency of the red, green and blue light emitting diodes.
