- Abstract
- We present a new method of driving an organic light-emitting diode (OLED) with an organic thin-film transistor (OTFT). The OTFT and the OLED were fabricated on separate substrates, namely on Si for the OTFT and on glass for the OLED and both devices were laminated with silver paste. After driving a 2 mm × 2 mm OLED with an OTFT devices, we obtained 105 cd/m2 from the green OLED with a drain current of 60 μA, a drain voltage of -50 V and a gate voltage of -40 V. For the white OLED (WOLED), we obtained 260 cd/m2 with a drain current of 108 μA, a drain voltage of -60 V and a gate voltage of -60 V. © 2005 Elsevier B.V. All rights reserved.
