Color Alignment - TAMUZ LSM 124W Operation Manual

Alignment of LCD Monitors
The color reproduction is measured in 256 gray levels in each color channel and got recalculated as
an internally Gamma look-up-table (LUT) newly. Possible external influences, f.e. protection filter or in-
put signal processing characteristics are taken into account.
The Gamma LUT can be adapted to the desired color temperature.

Color Alignment

The aim of the monitor calibration is the adaptation of the color reproduction to standardized values.
The adaptation to daylight corresponds to a color temperature of 6.504° K (D65). Within the CIE color
space this white can be assigned to specific coordinates: x=0,313 and y=0,329.
The grey line in the picture above shows the ideal course (Planck's curve) of a black body. To align
the monitor shall effect, that the reproduced white color lies on this line exactly. Common Colormetrie
measurement tools displays the measured values as CIE color space coordinates, or as the deviation
dE of the ideal Planck's curve.
The color alignment is perfect, when the measured value dE is as low as zero (±0,5 dE).
The factory default values for X and Y are named in the manufacturers data sheet. Common values
are X=290 and Y=312 to set the TFT panel on a suitable white.
With help of the TAMUZ AAC function it is possible to shift the so called XY-whitepoint individually
within the CIE coordinate system for a perfect color reproduction at the specific color temperature.

Note: All the LCD panels on the TFT market have different color reproduction of the TV color
space. Some are close to the EBU or SMPTE color space, some didn't fit them.
