"The new ETFOS Version 1.2 is a fundamental optical simulation tool for the development of highly efficient OLED structures. New features of this software like including several different emission zones are of major importance for developing efficient white light OLED structures containing more than one emitting material. The flexibility, speed, and reliability of this software combined with its huge variety of simulation tools concerning various physical key quantities like angular dependence, color coordinates, or reflection spectra allow further improvement and basic insight of OLEDs."

Jan Blochwitz-Nimoth, CTO Novaled GmbH, Dresden, Germany

"ETFOS is an outstanding program for assisting in the development of OLED displays. It provides the predictive capabilities, and physical insight into the optical performance that is needed to optimise your design. It's a fast and powerful package that a user will immediately benefit from."

Ian Parker, Materials Development Manager
DuPont Displays, Santa Barbara, USA

"I have used ETFOS extensively to investigate the emission zone in polymer light-emitting diodes and electrochemical cells. The speed, reliability, and flexibility of this software make it ideal for a wide range of applications, particularly in the optimization of device structures or in the fundamental research of device physics."
