Their sum is 408 cd / m2, which is identical to the measured
White Luminance, so there isn't any Dynamic Color or Contrast, only a Dynamic Backlight.

It is possible that the «laws» of perception we have explored so far evolved primarily to deal with shadows and to distinguish them from «real» objects, which would also produce
luminance differences in the visual scene as a result of differences in reflectance (for instance, a zebra's stripes or a
white cat standing on a black surface).
But when the black spaces are replaced by a green shade with the same
luminance as the blue (previously
white) spaces, the 3 - D character of the image falls apart (right).
It is possible that the «laws» of perception we have explored so far evolved mainly to deal with shadows and to distinguish them from «real» objects, which would also produce
luminance differences in the visual scene as a result of differences in reflectance (for instance, a zebra's stripes or a
white cat on a black mat).
The Measurements section below has details of all of the lab measurements and tests with lots of additional background information and explanations including the display's Maximum Brightness and Peak
Luminance, Black Brightness, Contrast Ratio, Screen Reflectance, Bright Ambient Light Contrast Rating, Dynamic Color and Contrast, Color Temperature and
White Chromaticity, Color Gamut, Intensity Scale and Gamma, the variation of Brightness, Contrast Ratio and Color Shift with Viewing Angle, Backlight Power Consumption, and Light Spectrum of the display.
Table 1 lists the Measured Relative Power, the Measured
Luminance, and the Relative Luminous Efficiency, which is just the Measured
Luminance divided by the Measured Relative Power, and normalized to 1.0 for
White, which has the highest total efficiency.
On the Google Galaxy Nexus, a close cousin of the Galaxy S III, the effect is so large for high APL that the Brightness (
Luminance) of Green is greater than
White, which is very wrong.
In fact, the effect on the Galaxy Nexus is so large that for high APL the Brightness (
Luminance) of Green is greater than
White, which is very wrong.
The display's maximum contrast is the ratio between its peak
white brightness (
luminance) and its darkest black
luminance, one of the more important measures of LCD performance quality.
Below CR HAL is the Peak
White display Brightness (
Luminance) in cd / m2.
Already one of the most rare super-SUV models, this Audi Q7 comes in Inuit, a special
white that creates a pearl effect reminiscent of the glistening
luminance of the polar region.
Contrast Ratio is the difference between the
luminance of the brightest
white and the darkest dark a display can produce.
Using flash in very low - light conditions, some
luminance noise is visible in the shadow regions, but overall
white balance, color rendering, and detail preservation remain good.
