Static Contrast
The standard procedure for contrast evaluation is as follows:
1 apply the first test pattern to the electrical interface of the display under test and wait until the optical response has settled to a stable steady state,
2 measure the luminance and/or the chromaticity of the first test pattern and record the result,
3 apply the second test pattern to the electrical interface of the display under test and wait until the optical response has settled to a stable steady state,
4 measure the luminance and/or the chromaticity of the second test pattern and record the result,
5 calculate the resulting static contrast for the two test patterns using one of the metrics listed above (CR,CM or K).
When luminance and/or chromaticity are measured before the optical response has settled to a stable steady state, some kind of transient contrast has been measured instead of the static contrast.

Famous quotes containing the word contrast:
“In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.”
—Hannah Arendt (1906–1975)
