New OLETs emit light more efficiently than equivalent OLEDs

Abstract:
Already, organic light-emitting diodes (OLEDs) are becoming commercialized for light display applications due to their advantages such as low fabrication costs and large-area emission. But OLEDs also have intrinsic efficiency limitations due to their structure, which might limit their future development in terms of brightness. Now, a team of researchers has found that another organic semiconductor-based device, the organic light-emitting transistor (OLET), can dramatically increase the efficiency of OLEDs since OLETs have the structure of a transistor rather than a diode. In their recent study, the researchers have created OLETs that are 10 times more efficient than any previously reported OLET, as well as more than twice as efficient as an optimized OLED made with the same materials.
