IEC 61988-2-1:2012 determines the following measuring methods for characterizing the performance of plasma display modules (PDP modules): a) four per cent (4 %) window luminance; b) luminance uniformity; c) dark-room contrast ratio; d) bright-room contrast ratio 100/70; e) white chromaticity and chromatic uniformity; f) colour gamut in the centre box; g) module power and current consumption; h) module power consumption using video signal; i) module luminous efficacy, and j) panel luminous efficacy. This edition includes the following significant technical changes with respect to the previous edition: The first edition of IEC 61988-2-1 and IEC 61988-2-2 were combined and reconstructed in this document.
