]]> Human-machine interfaces (HMI) are more and more present in our daily life and their definition increases with the evolution of screen technologies. OLED technology is one of these technologies and integrators must make choices of relevant suppliers to guarantee the visual performance of displays over time according to the intended uses.

With their skills in mechatronic systems and optical measurement, and equipped with suitable equipment, PISEO experts carry out accelerated aging test programs to check the reliability and optical performance of displays over time.
