摘要:
A Red, Green, Blue Light Emitting Device (RGB LED) backlight color control system includes an RGB LED backlight comprising a red LED, a green LED, and a blue LED. A driving current regulator is coupled to each of the red LED, the green LED, and the blue LED. A backlight power control is coupled to each of the driving current regulators and operable to receive adjustment data and use the adjustment data to adjust the driving current supplied by at least one of the driving current regulators to at least one of the red LED, the green LED, and the blue LED. By adjusting the driving current supplied to the red LED, green LED, and/or the blue LED, color pallet points on a color triangle (associated with a display that uses the RGB LED backlight) are shifted to achieve the color desired by the user, avoiding the loss of color pallet points in the color triangle that occurs with conventional re-mapping techniques.
