Provides an overview of the developments and applications of Organic Light Emitting Transistors (OLETs) science and technologyThis book discusses the scientific fundamentals and key technological features of Organic Light Emitting Transistors (OLETs) by putting them in the context of organic electronics and photonics. The characteristics of OLETs are benchmarked to those of OLEDs for applications in Flat Panel Displays and sensing technology. The authors provide a comparative analysis between OLED and OLET devices in order to highlight the fundamental differences in terms of device architecture and working principles, and to point out the enabling nature of OLETs for truly flexible displays. The book then explores the principles of OLET devices, their basic optoelectronic characteristics, the properties of currently available materials, processing and fabrication techniques, and the different approaches adopted to structure the active channel and to control organic and hybrid interfaces. Examines the photonic properties of OLETs, focusing on the external quantum efficiency, the brightness, the light outcoupling, and emission directionalityAnalyzes the charge transport and photophysical properties of OLET, emphasizing the excitonic properties and spatial emitting characteristicsReviews the key building blocks of the OLET devices and their role in determining the device’s performanceDiscusses the challenges in OLET design, namely color gamut, power efficiency, and reliabilityPresents key applications of OLET devices and their potential impact on display technology and sensingOrganic Light-Emitting Transistors: Towards the Next Generation Display Technology serves as a reference for researchers, technology developers and end-users to have a broad view of the distinguishing features of the OLET technology and to profile the impact on the display and sensing markets.

Michele Muccini is Director of CNR-ISMN and President of the public-private Industrial Consortium MIST E-R. He is co-founder of E.T.C. S.r.l., a start-up company of the SAES Group focussed on the development of organic light emitting technologies. Muccini is inventor of the OLET, the organic electroluminescent transistor and of the OCST, an organic sensor for the stimulation and recording of neural networks. He is author of about 160 scientific publications in international journals and inventor of 20 international patents related to OLET technology.Stefano Toffanin is a permanent researcher and leader of a group of 10 people focused on the development of flexible organic photonics and electronics at CNR-ISMN in Bologna. His main research interest is the spectroscopic investigation of light-emitting and charge-transport organic systems for use in organic nanostructured opto-electronic devices by means of non-conventional ultrafast optical probes. His current focus is on organic multifunctional flexible platforms for smart applications in nanophotonics and biodiagnostics. He is author of more than 40 papers and 4 international patents.
