31、NT AND MANAGEMENT - Part 4: Equipment using liquid crystal display panels I Scope A series of characteristics for colour reproduction and management, and the associated methods of measurement for use in multimedia systems and equipment, are applicable to the assessment of colour reproduction. This p

32、art of IEC 61966 deals with equipment using transmissive-type liquid crystal display (LCD) panels to display colour images for use in multimedia applications. The methods of measurement standardized in this part are designed to make possible the objective performance assessment and characterization

33、of colour reproduction of LCDs which accept red - green - blue analogue or digital signals from electrical input terminals and output colour images on LCD screens. For LCDs to which analogue signals are applicable, the corresponding digital signals are taken into account. The measured results are in

34、tended to be used for the purpose of colour management in multimedia systems. This part of IEC 61966 defines input test signals, measurement conditions and methods of measurement, so as to make possible the colour management and comprehensive comparison of the results of measurements. Colour control
