Information About

Thin-film Transistor




The channel region of a TFT is a thin film that is Deposited onto a substrate (often Glass , since the primary application of TFTs is in Liquid Crystal Display s).

Most TFTs are not transparent themselves, but their electrodes and interconnects can be. The first transparent TFTs, based on Zinc Oxide were reported in 2003 by researchers at Oregon State University .

The best known application of thin-film transistors is in TFT LCD s, a variant of LCD technology. Transistors are embedded within the panel itself, reducing crosstalk between Pixel s and improving image stability. As of 2004 , all but the cheapest color LCD screens use this technology.
