WG 10 - TC 113/WG 10

IEC TS 62607-3-5:2026, which is a Technical Specification, establishes a standardized method to determine the optical key control characteristic
• light conversion efficiency
for quantum dot enabled light conversion films (Q-LCFs) by
• luminance meter.
The light conversion efficiency is derived by the photoluminescence spectrum.
The typical application areas of this standardized measurement method are the nano-photoelectric display devices using Q-LCF as key component, and other relevant optical conversion devices.
WARNING – Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.

IEC TS 62565-4-3:2026, which is a Technical Specification, establishes a blank detail specification (BDS) for quantum dot enabled light emitting diodes (QLEDs) used for printed light emitting diodes (LEDs).
This document is intended to be used for display applications.
The relevant key control characteristics (KCCs) include optical, physical, chemical, and structural properties of colloidal quantum dots (QDs). For each KCC listed, methods and existing standards for their measurement are reported. The applicability of such methods and standards to different material categories (physical forms) of QDs, for example colloidal solution, inks, films, is indicated.
Numeric values for the KCCs are left blank as they will be specified between customer and supplier in the detail specification (DS). In the DS, KCCs can be added or removed if agreed between customer and supplier.

IEC TS 62565-4-4:2025 which is a Technical Specification, establishes a standardized method to determine a blank detail specification (BDS) for
- quantum dot enabled light conversion film (Q-LCF).
This document is intended to be used for nano-enabled photoelectric display, based on liquid crystal display (LCD).
The relevant key control characteristics (KCC) of Q-LCF are listed, including physical, mechanical and optical properties, and stability. For each KCC, measurement methods and existing standards are reported.
Numeric values for the KCCs are left blank as they will be specified between customer and supplier in the detail specification (DS). In the DS KCCs can be added or removed if agreed between customer and supplier.

IEC TS 62565-4-1:2019 establishes a blank detail specification and format for listing essential optical and certain other characteristics of monodisperse luminescent nanomaterials. This document does not address mixtures or agglomerations of luminescent nanomaterials.
In addition, this document enables the customer to specify requirements in a standardized manner and to verify through standardized methods that the luminescent nanomaterial meets the required properties.
Numeric values to be specified for the properties and characteristics in this document are intentionally left blank and are determined by agreement between customer and material supplier. Properties and characteristics deemed by the customer or supplier as not relevant to a specific application are classified as “not applicable” or “not specified”.
