Thin-film transistors (TFTs) are key elements for large area electronics, whose applications are increasingly pervading our society. TFT technology, involving multidisciplinary research topics, has far reaching impact in a number of areas including flat panel displays, organic electronics, system on glass, and flexible electronics. In 2005, due to the need for a conference related with TFTs, the International TFT Conference (ITC) was established to exchange ideas and information in the field of organic and inorganic TFTs. Seven years after the 8th ITC will be held in Lisbon from January 30 to 31 of 2012 convering the following topics:
