4.12 Mis-convergence
The maximum convergence error should be measured on a white
line and represents the maximum distance between the center
of the red, green and blue lines over the whole image area.
Max. Mis-convergence:
(Picture area X 2 See FIG-6)
4.13 Focus check
First, adjust brightness to 50 % position and contrast to100% position, and
then
generate "ME" characters for 1280 X 1024 / 85Hz or 1600 x 1200 / 85Hz
timings
to cover entire picture area (picture size is shown in sect. 4.5). Characters s
be clearly identified at the center and all corners. Character size is shown in
FIG-7.
4.14 Brightness uniformity
With an active full area white video input pattern and contrast
setting to 100%, no portion of the pattern shall be less
Than 75 % of the luminance measured at the CRT center.
4.15 White color adjustment
There are three factory preset white color 9300 K, 6500 K and 5500 K.
Apply full white pattern, with brightness in 50 % position
and the contrast control at max. position.
The 1931 CIE Chromaticity (color triangle) diagram (x, y)
coordinate for the screen center should be:
Y = 0.297 +/- 0.020
6500 K CIE coordinates X = 0.313 +/- 0.020
392mm 94mm
9300 K CIE coordinates X = 0.283 +/- 0.020
Y = 0.329 +/- 0.020
5500 K CIE coordinates X = 0.332 +/-0.020
Y = 0.347 +/- 0.020
