Mis-convergence
The maximum convergence error to be measured on a white spot or white display line to
represents tha maximum distance betwean the energy centers of any two primary colors
(See Fig. 6). For 31.5kHz modes B Zone : 0.4mm.
4.2 image size (For preset modes only)
The dimensions of guaranteed display area to ba measured along the picture center of
horizontal and vertical axis of the screen as listed below: (preset modes only, refer to fig. 1)
Width 306 + 3mm
Height 2230 + 3mm
CONVERGENCE SPEC.
4.3 Image centering deviation (For preset modes only)
With respect to fig. 2, the target relationships are the following :
IA- BI< 5mm IC- Dl < 5mm

Note : This centering is adjustable by the end-user.
4.4 Picture shift control range (For preset modes only)
Focus check ( 68.7 KHZ / 85 HZ )
Adjust brightness control to center(50%) and contrast control to get 25 FL
at full white pattem, then generate |mei characters to cover the entire picture.
The characters should be clearly identified in all display area. (See Fig. 8)
H-shift range :+ 10 mm min.
V-shift range :+ 10 mm min.
4.5 Picture tilt
With respect to Fig. 3, Tilt to be measured on extremes of center line from bezel.
Luminance uniformity
condition : With full white pattern, set contrast control at maximum(100%)
and brightness control at center(50%).
Brightness of the center of the display is 30 FL+/-5.
1A- BI :$2mm
4.6 Geometrical distortions (For preset modes only)
The Max. deviation over the screen should not exceed 25% .
itis acceptable that pincushion, trapezoid, rhomboid,
rotation and various waves distortions must remain within
the limits of tolerance as in Fig. 4,
where A = B = 2.0mm.
C=D=2.0mm.
The waviness of any vertical or horizontal shall be less than 1.0 mm over a 50 mm distance.

White color adjustment
Based on the 1931 CIE chromatic diagram (x,y) coordinates
of white display on screen center should be:

4.7 Image non-linearity (For praset modes only)
Apply cross-hatch pattern with
12 equal blocks along honzontal axis,
9 equal blocks along vertical axis. (see Fig. 1)
Overall : $10%
Adjacent: < 6 % (For 64kKHz mode H < 8 %)
Check conditions : Set brightness control at center(50%) and contrast at
maximum{ 100%).
For sRGB mode sRGB contrast Is at Factory value.
