IEC 61966-4 pdf download Multimedia systems and equipment – Colour measurement and management – Part 4: Equipment using liquid crystal display panels
1 scope
A series of characteristics for colour reproduction and management,and the associatedmethods of measurement for use in multimedia systems and equipment, are applicable to theassessment of colour reproduction. This part of lEC 61966 deals with equipment usingtransmissive-type liquid crystal display (LCD) panels to display colour images for use inmultimedia applications.
The methods of measurement standardized in this part are designed to make possible theobjective performance assessment and characterization of colour reproduction of LCDs whichaccept red – green – blue analogue or digital signals from electrical input terminals and outputcolour images on LCD screens.For LCDs to which analogue signals are applicable,thecorresponding digital signals are taken into account.The measured results are intended to beused for the purpose of colour management in multimedia systems.
This part of lEC 61966 defines input test signals,measurement conditions and methods ofmeasurement, so as to make possible the colour management and comprehensive comparisonof the results of measurements.
Colour control within equipment is outside the scope of this part. lt does not specify limitingvalues for various parameters.
