An organic light‐emitting transistor (OLET) integrates the field‐effect trans‐conductance characteristics of an (OFET) and electric‐injection properties diode (OLED). The corresponding active layer device achieves controllable photoelectric coupling conversions. Therefore, a new method is theoretically provided for studying carrier transmission exciton emission theory. Furthermore, integrated OLETs render their potential to advanced display technology, multifunctional optoelectronics, electrically pumped lasers. However, OLET devices are yet meet industrial requirements, mainly due limitations in material performance fabrication techniques. Herein basic factors that influence mobility luminescence semiconducting materials outlined recent reports on with focus design, fabrication, operational mechanisms summarized. More specifically, functional optoelectronic based high‐mobility emissive described, including OFET–OLED circuits same material, optical switching devices, waveguides. Herein, insight into design which may be great interest scientists working field, provided.
