Annotation of standard text IEC 61747-30-1-ed.1.0 :
IEC 61747-30-1:2012 is restricted to transmissive liquid crystal display-modules using either segment, passive or active matrix and achromatic or colour type LCDs. Furthermore, the transmissive modes of transflective LCD modules with backlights ON are comprised in this document. An LCD module in combination with a touch-panel or a front-light-unit is excluded from the scope because measurements are frequently inaccurate. Touch-panels or front-light-units are removed before measurement. Throughout the main body of this standard, an integrated backlight is assumed to provide the illumination for the measurements. Deviations from this (e.g. segmented displays without integrated backlights) may usually be handled in the same way as display modules with integrated backlight, if an external backlight is provided. However, in the case where one of the two situations should be handled differently, this will be specifically stated. This first edition cancels and replaces IEC 61747-6 published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the document structure was brought in line with 61747-6-2; and b) various technical and editorial changes were made. This publication is to be read in conjunction with IEC 61747-1:1998. La CEI 61747-30-1:2012 est limitee aux modules daffichage a cristaux liquides de type transmissif utilisant des dispositifs a cristaux liquides de type soit a segments, soit a matrice passive ou active et achromatique ou couleur. Ce document presente egalement les modes transmissifs des modules LCD transflectifs avec retro-eclairage allume. Un module LCD combine avec un panneau tactile ou une unite declairage frontal ne releve pas du domaine dapplication, car les mesures sont souvent erronees. Les panneaux tactiles ou les unites declairage frontal sont retires avant la mesure. Dans tout le corps de la presente norme, on suppose quun retro-eclairage integre assure leclairement utilise pour les mesures. Tout ecart par rapport a cette hypothese (par exemple, afficheurs a segments sans retro-eclairage integre) peut generalement etre traite de la meme maniere que les modules daffichage avec retro-eclairage integre, si un retro-eclairage externe est fourni. Toutefois, dans le cas ou il convient de traiter differemment lune des deux situations, cela sera specifiquement indique. Cette premiere edition annule et remplace la CEI 61747-6 parue en 2004. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) mise en correspondance de la structure du document avec la CEI 61747-6-2; et b) des modifications techniques et redactionnelles ont ete effectuees. Cette publication doit etre lue conjointement avec la CEI 61747-1:1998.
