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 with envy, which usually occurs between two people and is focused upon another persons qualities or possessions, jealousy occurs when a third person becomes a threat to a dyad. Jealousy involves the loss or the impending loss of a relationship that one wants to hold onto, a relationship that is vital to personal fulfillment and claimed as ones own.”
—Carol S. Becker (b. 1942)
