Colorimetric characterisation of a HD-PDP device

Colorimetric characterisation measurements were carried out on a 42" hi-h-definition Panasonic plasma display. Four generally applied mathematical colorimetric characterisation models were investigated from the point of view of colorimetric accuracy, based on the spectral measurement of 157 test colours: GOG, GOG including channel independence, GOG including black emission and sRGB. The model including black emission performed better than the model including channel interdependence. All models performed better than sRGB. The overall electro-optic transfer function was a power function similar to those of CRT monitors. This may result from a look-up table built-in the hardware of the device.
