Organic light-emitting diodes are well-recognized advantages in power consumption, viewing angle, response time, and contrast ratio over liquid crystal displays. The primary technical challenge preventing wider commercial implementation remains the drive transistor in the active matrix backplane. In order to commercialize such devices, it is necessary to develop new materials, propose new device processing, and design new device structures. Organic light-emitting transistors (OLETs) function as electroluminescence devices as well as driving transistors. They are very attractive not only for future flexible display applications but also from the standpoint of scientific interest such as emission mechanisms, organic laser operation, etc. In this paper, we describe recent progress of OLETs using organic semiconductor films and the fabrication and characterization of vertical type devices and the potential for the development of flexible organic electronic devices.
