Method and Apparatus for Color Calibration for Reduced Motion-Induced Color Breakup

Abstract:

A display panel is calibrated to a target white point. A maximum luminance value of the display panel is attenuated from a first luminance value associated with the target white point to a second luminance value based on an attenuation factor. The second luminance value is equal to or lower than the first luminance value. The display panel is re-calibrated based on a chromaticity of the target white point and the second luminance value to generate calibration data. The calibration data is flashed into memory associated with the display panel. During operation, the white point of the panel may be shifted from the target to a chromatically imbalanced (e.g., reddish) white point that may cause motion-induced color trail or color breakup artifacts. The attenuated second luminance value ensures the motion-induced color trail or color breakup artifacts are adequately masked when the panel is driven with the chromatically imbalanced white point.
