All tests shall be performed under the following conditions, unless otherwise specified.
Ambient light
Dark room (< 1 cd/m
2
)
Viewing distance
40 cm for LCD performance, 20 cm for LCD failures
Warm up time
>
30 minutes

Control temperature
6500
°
K
User brightness control
The value under user mode
User contrast control
Set to factory preset value, which allows that the brightest two of
32 linear distributed gray-scales (0
~
700mv) can be
distinguished.

e-color mode
Measurement systems
The units of measure stated in this document are listed below:
1 gamma = 1 nano tesla
1 tesla = 10,000 gauss
cm = in x 2.54
Lb = kg x 2.2
Degrees F = [°C x 1.8] + 32
Degrees C = [°F - 32]/1.8
v' = 9y/(-2x + 12y + 3)
x = (27u'/4)/[(9u'/2) - 12v' + 9]
y = (3v')/[(9u'/2) - 12v' + 9]
nits = cd/(m2) = Ft-L x 3.426
lux = foot-candle x 10.76
