Organic light-emitting transistors (OLETs) combine the switching properties of a transistor with the emission properties of a light-emitting diode in a single device. Such multifunctional devices can potentially simplify the circuitry for displays and can provide very high electroluminescence quantum efficiencies. Also, the planar geometry allows integration of various optical components such as waveguides and resonators with the transistor platform for more complex devices. Finally, OLETs are suitable model systems for studies of various physical processes in organic devices including charge injection and transport as well as emission processes. In this chapter, we review some of the latest developments in the field of OLETs. The first part describes the device geometry, fabrication processes and typically used materials, while the second section discusses the light-generation processes. The third section will provide examples of OLET devices with integrated photonic elements to spectrally tune the emission, while the fourth and final section will provide a summary and outlook.
