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.
