Vertical Organic Light Emitting Transistor (VOLET)

In what kinds of applications does the “Vertical (Organic) Field Effect Transistor VOFET” have advantages over others architectures?

-One of the most promising applications of VOFETs is in the development of VOLETs (Vertical Organic Light Emitting Transistor). With this architecture, it is possible to have in only one device, an OLED (Organic Light Emitting Diode) and a switching control (due to the gate voltage applied).
