Abstract
The present invention provides a backlight module, wherein the backlight module comprising a plurality of Light Emitting Diodes (LED) in different colors, and an apparatus for controlling this backlight module. This controlling apparatus comprises: a plurality of driving units, a plurality of photosensor units, a plurality of transforming units and a plurality of control units. The driving unit is used to drive those LEDs. The photosensor unit is used to sense the mixed-light mixed by lights emitted by those different colored LEDs and generate a plurality of first electrical signals. The transforming unit is used to transform those first electrical signals into a plurality of second electrical signals. The control unit is used to receive those second electrical signals and drive the driving unit which will drive those LEDs and control those LEDs' brightness with the frequency of those second electrical signals.
