In February 1957, [[J. Torkel Wallmark|John Wallmark]] of [[RCA]] filed a patent for a thin film [[MOSFET]]. [[Paul K. Weimer]], also of [[RCA]], implemented Wallmark's ideas and developed the [[thin-film]] [[transistor]] (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of [[cadmium selenide]] and [[cadmium sulfide]].

The idea of a TFT-based [[liquid-crystal display]] (LCD) was conceived by [[Bernard J. Lechner|Bernard Lechner]] of [[RCA Laboratories]] in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the [[dynamic scattering]] mode of LCDs.<ref name="Kawamoto">{{cite journal |last1=Kawamoto |first1=H. |title=The Inventors of TFT Active-Matrix LCD Receive the 2011 IEEE Nishizawa Medal |journal=Journal of Display Technology |date=2012 |volume=8 |issue=1 |pages=3–4 |doi=10.1109/JDT.2011.2177740 |bibcode=2012JDisT...8....3K |issn=1551-319X}}</ref> In 1973, [[T.

By 2013, most modern [[high-resolution]] and high-quality [[electronic visual display]] devices used TFT-based active matrix displays.<ref>{{cite book |last1=Brotherton |first1=S.

As of 2024, TFT LCD displays are still dominant, but compete with [[OLED]] for high brightness and high resolution displays, and compete with [[electronic paper]] for low power displays.
