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.

Anzeigen mit organischen Leuchtdioden (OLEDs) - Teil 6-3: Messverfahren für Bildqualität

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.

Prikazovalniki z organskimi svetlečimi diodami (OLED) - 6-3. del: Merilne metode za kakovost slike

Ta del standarda IEC 62341 določa standardne merilne pogoje in merilne metode za ugotavljanje kakovosti slike prikazovalnih modulov in plošč z organskimi svetlečimi diodami (OLED). Bolj natančno, ta standard se osredotoča na pet specifičnih vidikov kakovosti slike, na primer na širino vidnega kota, presluhov, utripanja, ločljivosti statične slike in premikajoče slike.
