Simple Single-Station OLED Device IVL and Viewing Angle Testing System

For users from OLED research institutions who prioritize testing functions and accuracy over testing efficiency, the single-station IVL and viewing angle testing system can be chosen. Compared with multi-station machines, only one viewing angle-equipped station and fixture are retained, making the machine size more compact. Meanwhile, the optional industrial visual alignment camera can be omitted.

Settings for I-V-L Curve Measurement

1. The starting voltage, ending voltage, and voltage step can be set for continuous measurement.
2. The starting current density, ending current density, and current density step can be set for continuous measurement.
3. A separate lower limit for luminance detection based on current density can be set: when below the lower limit, only current and voltage are measured; when exceeding the lower limit, voltage, current, luminance, and other data are measured simultaneously.
4. The set machine model parameters can be saved and directly recalled for the next measurement.

I-V-L Measurement Data

Measurement results include: luminance L (cd/m²), current efficiency (mA/cm²), luminous efficiency, external quantum efficiency, chromaticity coordinates (x, y), color temperature, color rendering index (CRI), and luminous spectrum.

Charts included in the output measurement report: Cdens-V, Cdens-L, Cdens-LumE, Cdens-EQE, CIE1931, and Spectra.
