Note 4: The definition of contrast ratio (Test LCM using PR-705):

Contrast Ratio (CR) =

Luminance When LCD is at “White” state

Luminance When LCD is at “Black” 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 “black” to

“white” (falling time) and from “white” to “black” (rising time), respectively.

The response time is defined as the time interval between the 10% and 90% of amplitudes. Refer to figure

as below.

Note 6: Definition of Color of CIE Coordinate and NTSC Ratio.

Color gamut:
