20100079365 | Methods and systems for LED backlight white balance - Aspects of the present invention relate to systems and methods for performing white balance operations for an LED display backlight. One method comprises obtaining display parameters and capturing sensor data for a display. Geometrical calibration between the captured sensor data and the display is performed. Color conversion matrices for the display backlight may also be calculated. The backlight is displayed at a selected white value and measurement of the actual color of the backlight is then performed. Next a target luminance is determined based on the measured backlight color and minimization of visible luminance variation. A target color is then determined and used to determine a color difference between the measured backlight color and the target color. From this a normalized RGB color difference and RGB color difference driving values are determined. New RGB driving values based on the RGB color difference values and original driving values are then determined. | 04-01-2010 |
