New Guide Available: Ossila's Guide to OLED Testing (Lifetime & Performance)

Posted on Tue, May 30, 2017 by Ashley Wong

Whether you are new to the world of testing OLEDs, or just want to try a new method of doing so, we have created a detailed video and written guide to OLED testing aimed at providing a helpful overview of the subject. Specifically, this guide covers two basic types of OLED testing - general performance testing and lifetime testing.



Written by Ossila's Marie Curie EU Excilight Network PhD student, Marco Collela, this guide offers a step-by-step outline of OLED charaterisation and measurement, all from a researcher's perspective. It covers the procedures, data collection methods, equipment needed and data extrapolation methods. For this guide, we used our OLED Lifetime System, consisting of: an XtralienTM X100 Source Meter, a Multiplexor Test Board and a photodiode lid.


Lifetime extrapolation from accelerated tests. The black circles represent the experimental data. The dashed line represents the fit.

We took care to include a particularly detailed summary on data extrapolation, delving into two specific extrapolation methods: Stretched Exponential Decay (SED) and Accelerated Lifetime Testing.

As we are always looking for ways to improve and create better content for our readers, we welcome feedback form our customers using this form. We would love to hear your thoughts on this guide, as well as any suggestions for future guides/content - so please don't hesitate to leave us a message via the feedback form.

P.S. We will be making a corresponding OLED Fabrication Guide and video very soon, so keep a look out for that in the near future!
