Organic light emitting diode (OLED) displays - Part 6-3: Measuring methods of image quality

IEC 62341-6-3:2012 specifies the standard measurement conditions and measuring methods for determining image quality of organic light emitting diode (OLED) display panels and modules. More specifically, this standard focuses on five specific aspects of image quality, i.e., the viewing angle range, cross-talk, flicker, static image resolution, and moving image resolution.

Afficheurs à diodes électroluminescentes organiques (OLED) - Partie 6-3: Méthodes de mesure de la qualité des images

La CEI 62341-6-3:2012 spécifie les conditions et les méthodes de mesure normalisées pour déterminer la qualité des images des panneaux et des modules d'affichage à diode électroluminescente organique (OLED: Organic Light Emitting Diode). Plus spécifiquement, la présente norme porte sur cinq aspects spécifiques de la qualité des images, à savoir la largeur d'angle de visualisation, la diaphonie, le papillotement, la résolution des images statiques et la résolution des images animées.
