Abstract
The embodiments of the present invention relate to a color management method and device, the method comprises: RGB values is acquired from image signal inputted from external device; the corresponding transmittance of red pixel, transmittance of green pixel, and transmittance of blue pixel are calculated with an formula according to said RGB values and pre-stored system transition matrix with standard transition matrix; a control signal to control a driving voltage and/or luminance of light source corresponding to the red, green and blue pixels of the display device is generated according to the calculated transmittance of red pixel, transmittance of green pixel, and transmittance of blue pixel, so as to control the display device to perform the color display. The color management method enables the display device to accurately restore the reproduction color information, thereby effectively solving the color distortion problem of the display device.
