Curved organic light emitting diode (OLED) light source Optical performance test methods

1 Scope

This document describes the optical performance test of curved organic light emitting diode (OLED) light sources for display (hereinafter referred to as "curved light sources"). method.

This document is applicable to the optical performance test of curved light sources bent around one axis.

2 Normative references

GB/T 20871.2-2007

3 Terms and definitions

The terms and definitions defined in GB/T 20871.2-2007 and the following apply to this document.

3.1 curvedlightsource

A light source with a fixed radius of curvature in a particular direction.

Note. The bending axis is usually horizontal or vertical, and the bending direction is concave or convex relative to the observation position.

3.2 fixed-pointtest

At the same observation point in front of the curved light source, test each test point on the curved light source.

Note. In this document, the fixed point of the test is located on the horizontal plane where the center of the curved light source is located and on the line connecting the curved axis of the curved light source.

3.3

The brightness at other test angles compared to the brightness at 0° in the normal direction.

3.4

The chromaticity at other test angles compared to the chromaticity at 0° in the normal direction.

4 Test system layout

4.1 Overview

The layout of the test system is shown in Figure 1.The axis of the test equipment is consistent with the center line of the test curved light source surface.

The test distance is 1M, 3V is recommended, and V is the effective height of the screen.
