  • Display device with color and luminance characterization and compensation methods
    Patent number: 10276081
    Abstract: Improved display devices, information handling systems and related methods are provided for color and luminance characterization and compensation. According to one embodiment, a characterization method is provided for correlating the color/luminance measured from light emitted by a light source disposed within the display device to the color/luminance measured from light output from the display device at the time of manufacture. After the display device is characterized and a set of characterization values are stored, a compensation method is used during operation of the display device to perform color/luminance compensation for the light output from the display device by measuring the color/luminance of the light source illumination, and adjusting color gain values to maintain the color/luminance of the output light at a reference set point.
