This part of IEC 61966 deals with equipment using plasma display panels (PDP) to display colour images for use in multimedia applications. The methods of measurement standardized in this part of IEC 61966 are designed to make possible the objective performance assessment and characterization of colour reproduction of PDP displays which accept red green blue analogue or digital signals from electrical input terminals and output colour images on PDP display screens. For PDP displays to which analogue signals are applicable, the corresponding digital signals are taken into account. The measured results are intended to be used for the purpose of equipment specific colour control in order to attain colour management in open multimedia systems. This part of IEC 61966 defines input test signals, measurement conditions, methods of measurement and reporting of the measured data, so as to make possible the colour management and comprehensive comparison of the results of measurements. Colour control within equipment is outside the scope of this part of IEC 61966. It does not specify limiting values for various parameters. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of 61966.
