Overview - IEC TR 62595-1-6:2025 (Quantum dot films and diffuser plates)

IEC TR 62595-1-6:2025 is a Technical Report from IEC TC 110 that gives background and guidance for future standardization of quantum dot light converting units used in display backlight units (BLUs). The document focuses on photoluminescent BLUs and describes quantum dot films (QD‑LCF) and quantum dot diffuser plates (QD‑DP), their role in backlights, and examples of how QD light converting units affect optical performance after environmental tests.

Key topics and technical content

Definitions and terminology: precise terms such as quantum dot (QD), QD-LCF, QD-DP, QD-LGP and QD-LCU are defined to support consistent use in BLU applications.

Quantum dot technologies: comparison of common QD implementations for BLUs:

QD‑LCF (film sandwiched between barrier layers) - thin, flexible, widely used in edge‑lit and direct‑lit BLUs.
QD‑DP (diffuser plate infused with QDs) - cost‑competitive option for some direct‑lit TV applications.
Other forms noted: QD tubes/bars, QD‑LGP, and QDoC (quantum dot on chip).

Optical characteristics: how QD light conversion changes spectra, improves colour purity and colour gamut, and influences luminance and uniformity. The report describes factors influencing colour gamut, luminance and uniformity for QD‑BLUs.

Mechanical and environmental characteristics: examples and data from tests that illustrate how QD‑LCU optical characteristics change after:

High temperature storage
High temperature and high humidity
Blue light operation tests (including an informative Annex on high‑flux blue aging)
Release force and durability considerations

Discussion on future standardization: recommendations and topics for potential normative work covering QD films and diffuser plates.

Practical applications and target users

This TR is practical for:

Display manufacturers and design engineers specifying or integrating quantum dot films and diffuser plates into LCD backlights.

Material suppliers (QD manufacturers, barrier films, diffuser materials) and LED/LD system providers.

Test laboratories and quality assurance teams evaluating BLU optical stability after environmental stress.

Standards committees and product spec writers preparing normative test methods and performance criteria for QD‑based BLUs.
