A palette of 766 luminance values can be measured in 12 minutes. A method is reported to acquire the uLR of LCD displays, generate a LUT to achieve precise calibration, and assess the accuracy of the calibration results. Accurate grayscale calibration of LCD devices thus requires a measurement of the luminance for the full palette of possible output values. The uLR of liquid crystal display (LCD) systems is poorly behaved with significant discontinuities occurring in the relative luminance changes. The calibration LUT is deduced from the uncalibrated luminance response (uLR) of the display system. Grayscale medical monitors are commonly calibrated by transforming the image display values sent to a graphic controller using a lookup table (LUT).
