The rapid development of charge transport and light‐emission in organic materials in the last decades has advanced the field of organic optoelectronics, highlighting the high potential of light‐emitting devices for industrial applications. Demonstrated for the first time over 15 years ago, light-emitting field-effect transistors (LEFETs) have transformed from an optoelectronic curiosity to a serious competitor in the race for cheaper and more efficient displays, also showing promise for injection lasers. Thus, what is a LEFET, how does it work, and what are the current challenges for its integration into mainstream technologies? The talk will shed some light on these questions. The fundamental working principle of LEFETs, materials that have been used, and device physics and architectures involved in the progression of LEFET technology for displays will also be discussed. Finally, the state‐of‐the‐art development of LEFETs will be presented as prospect avenues for the future of research and applications in this area.
