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

Posted on 30 May 11:03

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 have attached a feedback form at the end of this OLED testing guide. 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!
