|A- B| ≤ 2 mm
4.8 Misconvergenc
4.10 Focus
4.10.1 Adjust brightness control to center click and contrast control to get 25FL at Full white pattern, Then generate
“me” characters should be clearly identified in all display area
4.11 Jitters
No visible
4.12 White balance
4.12.1 Color temperature Using the CIE color temperature coordinate system
Color 9300
o
K x = 0.283+0.018 y = 0.297+0.018
Color 6500
o
K x = 0.313+0.018 y = 0.329+0.018
User Adjustment x = 0.313+0.018 y = 0.329+0.018
4.12.2 Color purity Impurity should not appear in the pattern of all green all red all blue or all white
4.12.3 Color tracking: When the full white pattern is displayed at preset (only for 9300 K) condition. The difference
of white balance between contrast 30 FL and low contrast 3 FL must be less than following value
x at contrast 30 FL - x at 3 FL < 0.018
y at contrast 30 FL - y at 3 FL < 0.018
4.13 Light output Set brightness 50%, Contrast 100% in 53.6 KHz 800x600 mode.
4.13.1 HL => At 70mm x 70mm white block pattern 43 - 53 FL at Contrast 100%, Brightness 50%
4.13.2 ABL => At full-white pattern 28 - 32 FL at Contrast 100%, Brightness 50%
à At full-white pattern 32-42 FL at Contrast 100%, Brightness 100%
LL => At full-white pattern 0.8 – 1.8 FL at Contrast 0%, Brightness 100%,
à At full white pattern < 0.3FL at Contrast 0%, Brightness 0%,
4.14 Luminance uniformity
Condition: With full white pattern, Set contrast control at maximum position and brightness control at center click
position
4.14.1 The center of the display is 30 FL. , the Max. deviation of the screen should not exceed 25%
4.15 Size regulation
4.15.1 Variation of image size (For preset modes only)
Due to brightness change : < 1.0%
(Set brightness control at center click, turn contrast control from Min. to Max.)
Due to aging
(25 degree C, 300hrs) : < 2.0%
Due to mains voltage
Variation (+ 10%) : < 1.0%
4.15.2 Static regulation
Picture growth from minimum light output to maximum light output shall be less than 3mm when picture is
exchanged from
