Abstract

The application of organic transistors in backplane technology is strongly hindered by their perceived instability to current and bias stress. High-performance polymer organic semiconductors with unprecedented electrical stability under ambient conditions are demonstrated. Remarkably, these unencapsulated, solution-processed organic transistors show slightly better bias stress stability than even the the current benchmarks for flat panel displays, a-Si and IGZO. Moreover, the transistors show a high mobility of about 3 cm(2) V-1 s(-1) and high on/off ratio of 10(6), combined with excellent reproducibility. These results demonstrate that solution-processed organic thin-film transistors have reached a stage that makes them suitable for commercialization in flexible backplane technology.
