Patent ID: 7708419

Claim:
An ambient light system for a TV having a liquid crystal display (LCD) panel, the ambient light system comprising: a plurality of ambient light sources, the ambient light sources implemented with a plurality of backlight sources included in a backlight module located at a back of the LCD panel; an audio level detector detecting a level of an input audio signal to be played by a loudspeaker of the TV to obtain a detected level, the level of the input audio signal corresponding to a volume of the input audio signal; a pattern generator generating an ambient light pattern by reference to a selected operation mode when the detected level satisfies a predetermined condition; and an ambient light controller providing a control signal to control the intensity of one or more of the ambient light sources based on the ambient light pattern to provide ambient light at the back of the display panel, wherein, the selected operation mode is a temporal ambient mode or a spatial ambient mode, and the temporal ambient mode provides the corresponding ambient light pattern to the ambient light controller for controlling the ambient light sources generating ambient lights with different luminance at different time, so as to provide a flickering ambient light at the back of the LCD panel; and the spatial ambient mode provides the corresponding ambient light pattern to the ambient light controller for controlling the ambient light sources generating ambient lights with different luminance at different locations, so as to provide a non-uniform ambient light at the back of the LCD panel.
