Note :
1. Screen displays at 34 preset modes
2. Screen displays perfect picture at 15 preset modes
3. Screen displays visible picture with OSD warning when
input modes are other then 34 preset modes
2.1.3 Timing requirements
The analogue color LCD monitor must be capable of
displaying standard resolutions within the vertical frequency
range of 56
-
76 Hz, the horizontal scan range of 30 -82 KHz
and others modes which be defined as section 5.1.2.
2.1.4 Brightness output (Video signal 0.7V ± 2 %)
use OSD to set R, G, B gain at 100%
measured by at screen center (position 5) as pattern1 on
next page
+/-
Brightness control Contrast control Light output unit: nits
100% 100% >= 200
2.1.4 Dimming range
Set the contrast at 50 %, Measure brightness at 0% and 100%
of brightness control the light output should be comply with
Luminance at brightness minimum
< 30 %
Luminance at brightness maximum
2.2 Scanning
2.2.1. Display mode
: Multi-modes
2.2.2. Horizontal scanning
Sync polarity : Positive or negative
Scanning frequency : 30K - 82 K Hz
2.2.3. Vertical scanning
Sync polarity : Positive or negative
Scanning frequency : 56 - 76 Hz
2.3 White balance adjustment
9300°K CIE coordinates
x = 0.283 + 0.02/- 0.02
y = 0.297 + 0.02/- 0.02
6500°K CIE coordinates x = 0.313 + 0.02/- 0.02
y = 0.329 + 0.02/- 0.02
2.4 Check brightness uniformity
Set contrast at 50% and turn the brightness to get average
above 200 nits.
Apply the pattern 1. It should comply with the following formula:
Minimum luminance of nine points (brightness)
>= 0.75 (Min.)
Maximum luminance of nine points (brightness)
2.5 Check Cross talk
Apply Pattern 2. Set contrast at 50% and brightness at 100 %.
Measure A.
Then output Pattern 3 and measure A’. The cross talk value:
ABS ( A - A’ )
¾¾¾¾¾¾¾¾¾
X 100 % < 1.5 % (Max)
A
2.6 Check picture flicker (B)
Apply a 1280*1024 /60Hz signal with pixel on/off pattern.
Set color temperature at original panel color.
Set brightness control at 100%, and contrast control at 50%.
Check picture flicker should not be visible.
