4-3-1 Color Coordinates (Temperature)
Color temperature is a measurement of the
radiant energy transmitted by a color. For
computer monitors, the color temperature refers
to the radiant energy transmitted by white. Color
coordinates are the X and Y coordinates on the
chromaticity diagram of wavelengths for the
visible spectrum.
CONDITIONS
Measurement instrument: Color analyzer
Scanning frequency: 68 kHz/85 Hz
Display image: White flat field at
center of display area
Luminance: Maximum
PROCEDURE
Use the directions in sections 4-3-2 through 4-3-3
to adjust the color coordinates for:
9300K to x = 0.283 ± 0.02, y = 0.298 ± 0.02
6500K to x = 0.313 ± 0.02, y = 0.329 ± 0.02

CUTOFF” in left menu to set the “y”
coordinate to 0.298 ± 0.02.
4. Use control bar after selecting “RED
CUTOFF” in left menu to 0.283 ± 0.02.
* If color values can not be matched to desirable
values, repeat sequences 3 and 4 after
readjusting “GREEN CUTOFF” control.
