EN 61747-30-1:2012

Liquid crystal display devices - Part 30-1: Measuring methods for liquid crystal display modules - Transmissive type

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.

Flüssigkristall-Anzeige-Bauelemente - Teil 30-1: Messverfahren für Flüssigkristall-Anzeigemodule - Transmissive Ausführung

Dispositifs d'affichage a cristaux liquides - Partie 30-1: Méthodes de mesure pour les modules d'affichage à cristaux liquides - Type transmissif

La CEI 61747-30-1:2012 est limitée aux modules d'affichage à cristaux liquides de type transmissif utilisant des dispositifs à cristaux liquides de type soit à segments, soit à matrice passive ou active et achromatique ou couleur. Ce document présente également les modes transmissifs des modules LCD transflectifs avec rétro-éclairage allumé. Un module LCD combiné avec un panneau tactile ou une unité d'éclairage frontal ne relève pas du domaine d'application, car les mesures sont souvent erronées. Les panneaux tactiles ou les unités d'éclairage frontal sont retirés avant la mesure. Dans tout le corps de la présente norme, on suppose qu'un rétro-éclairage intégré assure l'éclairement utilisé pour les mesures. Tout écart par rapport à cette hypothèse (par exemple, afficheurs à segments sans rétro-éclairage intégré) peut généralement être traité de la même manière que les modules d'affichage avec rétro-éclairage intégré, si un rétro-éclairage externe est fourni. Toutefois, dans le cas où il convient de traiter différemment l'une des deux situations, cela sera spécifiquement indiqué. Cette première édition annule et remplace la CEI 61747-6 parue en 2004. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) mise en correspondance de la structure du document avec la CEI 61747-6-2; et b) des modifications techniques et rédactionnelles ont été effectuées.

Prikazovalniki s tekočimi kristali - 30-1. del: Merilne metode za module prikazovalnikov s tekočimi kristali - Prosojni tip

Ta del standarda IEC 61747 je omejen na module prosojnih prikazovalnikov s tekočimi kristali, ki uporabljajo segmentno, pasivno ali aktivno matrico, in akromatske ali barvne zaslone s tekočimi kristali (LCD). Poleg tega ta dokument vključuje tudi odsevne načine odbojno-prepustnih modulov zaslonov s tekočimi kristali z vključeno osvetlitvijo iz ozadja. Modul zaslona s tekočimi kristali s sledilno ploščico ali enoto za sprednjo osvetlitev ne spada v področje uporabe, ker meritve pogosto niso točne. Sledilne ploščice ali enote za sprednjo osvetlitev se pred merjenjem odstranijo. V glavnem delu tega standarda je predvideno, da svetlobo med meritvami zagotavlja vgrajena osvetlitev iz ozadja. Odstopanja od tega (npr. segmentni prikazovalniki brez vgrajene osvetlitve iz ozadja) se lahko običajno obravnavajo enako kot moduli prikazovalnikov z vgrajeno osvetlitvijo iz ozadja, če se zagotovi zunanja osvetlitev iz ozadja. Primeri, ko je treba enega od obeh primerov obravnavati drugače, so izrecno navedeni.
