DisplayMate has revisited their Mobile Display “Shoot-out” and updated it with a huge amount of information, including the shown-above chromaticity diagrams indicating the resulting gamut. Much to my surprise, the Motorola Droid outperforms every other phone (including the iPhone), although the Samsung Galaxy has the widest support. In reality, the Galaxy’s support actually makes the visuals worse by oversaturating the colors.
Figure 1 shows the measured Color Gamut for each of the Smartphones along with the Standard Color Gamut in black. The outermost white curve is the limits of human color vision – the horseshoe is the pure spectral colors and the diagonal is the line of purples. A given display can only reproduce the colors that lie inside of the triangle formed by its primary colors. Highly saturated colors seldom occur in nature so the colors that are outside of the Standard Gamut are seldom needed and are unlikely to be noticed or missed in the overwhelming majority of real images. Note that consumer content does not include colors outside of the Standard Gamut, so a display with a wider Color Gamut cannot show colors that aren’t in the original and only produce inaccurate exaggerated on-screen colors. The dots in the center are the measured color of White for each of the Smartphones along with the D6500 Standard White, which is marked as a white circle.
