Organic Active-matrix TFTs with Air-Stable Organic Semiconductors

摘要

Air-stable organic thin-film transistors (OTFTs) for active matrix (AM) displays are developed with dinaphtho[2,3-b:2', 3 '-f]thieno[3,2-b]thiophene (DNTT), which is a recently emerging organic semiconductor material. Compared to commonly used pentacene with the HOMO level of -5.0 eV, the deeper HOMO level of DNTT (-5.4 eV) renders it much more stable in air. Here, we demonstrate the first operation of the DNTT-TFT driven liquid crystal display (LCD).
