Note 4:
The definition of contrast ratio (Test LCM using PR-705):
Contrast Ratio (CR) =
Luminance When LCD is at âWhiteâ state
Luminance When LCD is at âBlackâ state
(Contrast Ratio is measured in optimum common electrode voltage)
Note 5:
Definition of Response time. (Test LCD using DMS501):
The output signals of photo detector are measured when the input signals are changed from âblackâ to
âwhiteâ (falling time) and from âwhiteâ to âblackâ (rising time), respectively.
The response time is defined as the time interval between the 10% and 90% of amplitudes. Refer to figure
as below.
The definition of response time
Note 6: Definition of Color of CIE Coordinate and NTSC Ratio.
Color gamut:
S=
area of RGB triangle
area of NTSC triangle
x 100%
