Organic optoelectronic materials enable new classes of device which could be important for consumer electronics. Organic light-emitting diodes (OLEDs) and thin-film transistors (OTFTs) have been developed toward ultrathin and power efficient mechanically flexible display and electronics systems with the easy processibility. For practical roll-to-roll fabrication of these organic devices, it is necessary to use unreactive cathodes with high workfunction with simple process at low cost. Therefore, this presentation will cover unconventional fabrication processes of flexible organic devices such as soft contact lamination, soft-contact optical lithography, solution metal printing, and etc. The characteristics of the OLEDs and OTFTs formed by the unconventional techniques will be discussed compared with the characteristics of the devices formed by the conventional vacuum evaporation. |
