Electrical Requirements
Standard Test Conditions
All tests shall be performed under the following conditions, unless otherwise specified.
Ambient light Dark room (< 1 cd/m2)
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 (e-Color set to “User” mode)
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 ° H and V
AC Supply voltage
230V± 5％, 50±3Hz
Ambient temperature 20+5℃
Humidity
65% ± 20%
Display mode 1680x1050, 60 Hz, 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
