【Abstract】 Recently,thin-film transistor(TFT),as the primary building blocks of active electronics,has been intensively studied,and considerable progress on its high performance material development and multifunctional application have been made. As an emerging additive preparation technology,inkjet printing has received wide attention in such preparation field as electronic functional devices because of its lowcost, environmental friendliness and masklessness. In this paper, the materials system for inkjet printing TFT is summarized.According to the corresponding classification and function,the three materials systems including semiconductor,insulator and electrode are introduced in detail,respectively. The effect of the three materials on the performance of TFT devices is also analyzed in depth. The materials system for inkjet printing TFT is prospected,and these provide the future materials selection direction for inkjet printing high-performance TFT.更多还原
