Electrical Requirements
Standard Test Conditions
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
Analog Input signal 700 mVss
Control temperature
6500° K
User brightness control The value under user mode
User contrast control
Set to The value under user mode, which allows that the brightest
two of 32 linear distributed gray-scales (0～ 700mv) can be
distinguished.
Picture position and size Factory preset value
Viewing angle 90°+/-20 ° H and 90°+/-10° V
AC Supply voltage
230V± 5％, 50±3Hz
Ambient temperature
20+5℃
Humidity
65% ± 20%
Display mode 1440x900, 75Hz, all white
e-color mode Set to “User” 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
u' = 4x/(-2x + 12y + 3)
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
