Abstract
Disclosed herein are embodiments of color management systems and methods for LED backlights. One exemplary system comprises: a collection device adapted to collect optical signals of the LED array, transform the optical signals into electric signals and send the electric signals; a control device connected with the collection device adapted to process the electric signals, compare processing results with calibration values and output brightness control signals according to comparison results; and a driver device connected with the control device adapted to adjust brightness of the LED array according to the brightness control signals. Embodiments of the disclosed technology can be used to effectively adjust the brightness of LED backlights and/or keep the color coordinate values of the backlights constant in order to help ensure display quality.
