Liquid crystal display devices - Part 6-2: Measuring methods for liquid crystal display modules - Reflective type

IEC 61747-6-2:2011 gives details of the quality assessment procedures, the inspection requirements, screening sequences, sampling requirements, and test and measurement procedures required for the assessment of liquid crystal display modules. The purpose of this standard is to indicate and list the procedure-dependent parameters and to prescribe the specific methods and conditions that are to be used for their uniform numerical determination. The contents of the corrigendum of January 2012 have been included in this copy.

Dispositifs d'affichage à cristaux liquides - Partie 6-2: Méthodes de mesure pour les modules d'affichage à cristaux liquides - Type réflexible

La CEI 61747-6-2:2011 définit de manière détaillée les procédures d'évaluation de la qualité, les exigences d'inspection, les séquences d'examen, les exigences d'échantillonnage ainsi que les procédures d'essai et de mesure requises pour l'évaluation des modules d'affichage à cristaux liquides. L'objectif de la présente norme est d'indiquer et d'énumérer les paramètres qui dépendent de la procédure, ainsi que de prescrire les méthodes et conditions spécifiques à utiliser pour en obtenir une détermination numérique uniforme. Le contenu du corrigendum de janvier 2012 a été pris en considération dans cet exemplaire.

Prikazovalniki s tekočimi kristali - 6-2. del: Merilne metode za module prikazovalnikov s tekočimi kristali - Odsevni tip

Ta del IEC 61747 podaja podrobnosti postopkov ocenjevanja kakovosti, zahteve za pregled, zaporedja projiciranja, zahteve za vzorčenje ter preskusne in merilne postopke, potrebne za ocenjevanje modulov prikazovalnikov s tekočimi kristali. Ta standard je omejen na module odsevnih prikazovalnikov s tekočimi kristali, ki uporabljajo segmentno, pasivno ali aktivno matrico, in akromatske ali barvne LCD (glej opombo). Poleg tega ta standard vključuje tudi odsevne načine odbojno-prepustnih modulov LCD z izključeno osvetlitvijo iz ozadja in odsevne module LCD s sprednjo osvetlitvijo brez enote za sprednjo osvetlitev. Odsevni modul LCD s kombinacijo tipkovnice na dotik ali enoto za sprednjo osvetlitev je zunaj okvira uporabe tega standarda, ker meritve pogosto niso točne. Preden se vključi v obseg uporabe, je treba tipkovnico na dotik ali enoto za sprednjo osvetlitev odstraniti. Namen tega standarda je prikazati in navesti parametre, odvisne od postopkov, in predpisati specifične metode in pogoje, ki se uporabljajo za njihovo enotno številčno določevanje.
