Integrating organic light-emitting diode and field-effect-transistor in a single device

Field Emission Organic Light Emitting Diode

In recent years, the developments in the OLEDs have gradually reached very advantageous of existence. These advantageous characteristics include self-luminous, wide viewing angle and low power consumption, etc. which make OLEDs very useful for numerous display applications and lighting devices. To effectively improve the characteristics of an OLEDs, there are many ways to be adopted. Such as: (...

Integration of organic light-emitting diode and organic transistor via a tandem structure

A high-performance organic active matrix pixel was fabricated by using a metal oxide sV2O5d coupling layer that effectively integrates an organic light-emitting diode sOLEDd on top of an organic field-effect transistor sOFETd. The field-effect mobility of the OFET approached 0.5 cm2 V−1 s−1 and the ON/OFF current ratio was .103. The brightness of the OLED was on the order of 2000 cd/m2, with an...

Organic light-emitting transistor technology

The organic light-emitting transistor (OLET) is an emerging optoelectronic device having the structure of a thin-film transistor and the capability of light generation [1]. Bright/multicolor OLETs may allow electroluminescent display fabrication with simpler driving circuits. Furthermore, the most advanced OLETs encompass a huge technological potential for the realization of intense nanoscale l...
