Polarizing film for organic light-emitting displays

1 Scope

GB/T 46177-2025 is the Chinese national standard covering the circular polariser on an OLED panel - the one that kills the reflection of ambient light off the metal cathode, with its transmittance and degree of polarisation, the retarder layer, the adhesion, and the durability under heat, humidity and ultraviolet. Without it an OLED screen is a mirror in daylight. First edition, in force from 1 May 2026. Issued on 5 October 2025, it has been in force since 1 May 2026.

This document defines the terminology and definitions for polarizers used in organic light-emitting displays, and specifies the requirements, inspection rules, marking, packaging, transportation, and storage. The document describes the corresponding experimental methods. This document applies to both active-matrix driven organic light-emitting diodes (AMOLEDs) and passive-matrix driven organic light-emitting diodes. Design, research and development, production, delivery and inspection of polarizers for PMOLED displays.

3 Terms and Definitions

The terms and definitions defined in GB/T 31379.1-2025, GB/T 31379.2-2025 and GB/T 31379.3-2025, as well as the following terms and definitions. This applies to this document.

3.1 A display panel that uses organic light-emitting diodes (OLEDs) to display information.

3.2 ellipticity A physical quantity used to describe the changes in the direction and intensity of polarized light vibration. Note

1.The closer the periodic trajectory of the endpoint of the electric vector of the light wave is to a circle, the closer its ellipticity is to 1. Note

2.The ellipticity of a light wave is determined by measuring its amplitude in two orthogonal directions.
