This review aims to provide a technical roadmap and progress update for backplane thin film transistors (TFTs) used in organic light emitting diodes flat panel displays and next-generation flexible displays. In the introduction, we provide a general overview as well as trends in research on backplane TFTs. The main section describes current technical level and future prospects for amorphous metal oxide, semiconducting carbon nanotube, 2D transition metal dichalcogenide, and organic TFTs. The summary and prospects are provided in the conclusion.

Single-walled carbon nanotube (SWNT) is a promising candidate for infrared (IR) detectors due to its strong optical absorption in IR wavelength region, excellent charge carrier mobility and solution processability. Because large-diameter semiconducting SWNT (sc-SWNT) shows narrow band gap and weak exciton binding energy, it is advantageous to utilize large-diameter sc-SWNTs for IR detectors. For the use of sc-SWNTs, it is necessary to sort tubes with certain kinds of electrical properties from as-synthesized SWNTs bundles. Here, we report the sorting technique of large-diameter sc-SWNTs by conjugated polymers and high performances of sc-SWNT IR detectors.
