NIST performs first comparison of the gamut assessment standard with other NMIs. (General Developments).

A NIST scientist conducted interlaboratory color measurement comparisons with the National Physical Laboratory (NPL) of the United Kingdom and the National Research Council (NRC) of Canada. These measurement intercomparisons among national metrology institutes (NMIs) and the NIST Display Metrology Project kick off the first phase of interactions aimed at reducing the variability of color gamut and other measurements used to characterize and specify performance of electronic displays. A key feature of the project is the development by NIST of a standard illumination source fitted with color filter artifacts selected to test the instruments and methods used in display measurement. The device, the Gamut Assessment Standard (GAS), will initially be circulated among additional NMIs, instrument manufacturers, and industry laboratories to evaluate the measurement variability of the display industry. Later, the device will form the basis of a NIST-calibrated transfer standard--Display Measurement Assessment Transfer Standard (DMATS), allowing industry laboratories to evaluate their measurement procedures and instruments.
