To improve the image quality of a mobile display, the balance between color-gamut size and luminance was studied in two subjective experiments. The first experiment was performed during the Asian Society for Information Display (ASID) conference in Nanjing, February 2004. Nearly 600 participants ranked the quality of images displayed for fixed combinations of color-gamut size and display luminance on small color supertwisted nematic (CSTN) and thin-film transistor (TFT) twisted-nematic (TN) displays. In the second experiment, a broader range of color-gamutsizes and luminance levels were simulated on a cathode-ray tube (CRT) display, and 20 participants were asked to score perceived image quality. The results of these experiments were used to model image quality as a function of color-gamut size and display luminance for images differing in the level of chromaticity of their content. This model can be used to estimate the increase in luminance required to compensate for a reduction in color-gamut size. © Copyright 2006 Society for Information Display.
