Organic thin-film transistors (OTFTs) have received worldwide academic and industrial attention owing to their attractive features of low cost, low temperature drop-on-demand printable processes, superior intrinsic mechanical flexibility, and sustainable performance improvement. These features of OTFT bring them great potential for a wide range of new applications including flexible display and sensors. However, even with significant technological advances, there is still a gap for the OTFT technology to be widely commercially adopted. Based on actual application demand, this paper provides a comprehensive review of the OTFT development, and discuss its current status, opportunities and challenges.
