In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET in which germanium monoxide was used as a gate dielectric. 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
The concept of a thin-film transistor (TFT) was first proposed by John Wallmark who in 1957 filed a patent for a thin film MOSFET in which germanium monoxide was used as a gate dielectric. Thin-film transistor was developed in 1962 by Paul K. Weimer who implemented Wallmark's ideas. [16] The TFT is a special type of MOSFET. [17]
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 Lechner of RCA Laboratories in
John Torkel Wallmark (4 June 1919 – 5 February 2007) was a Swedish electrical engineer and researcher in semiconductor electronics and innovation technology. Torkel Wallmark was born in Stockholm. He graduated from the Royal Institute of Technology in 1944, became technology licentiate in 1947 and technology doctor in 1953.
TFT may refer to: Electronics. Thin-film transistor, a type of transistor commonly used in flat-screen displays; Gaming. Teamfight Tactics, an auto battler game from ...
An oxide thin-film transistor (oxide TFT) or metal oxide thin film transistor is a type of thin film transistor where the semiconductor is a metal oxide compound. An oxide TFT is distinct from a metal oxide field effect transistor ( MOSFET ) where the word "oxide" refers to the insulating gate dielectric (normally silicon dioxide ).
Some TFT displays do not allow a user to disable this, and will prevent the upper and lower portions of the screen from being used forcing a "letterbox" format when set to a 4:3 ratio. [citation needed] The 1280 × 1024 resolution became popular because at 24 bit/px color depth it fits well into 4 megabytes of video RAM.
Gabriel Wallmark (born 21 January 2002) [1] is a Swedish athlete who specializes in the triple jump. He was the gold medallist at the World Athletics U20 Championships in 2021 [ 2 ] [ 3 ] and at the European Athletics U20 Championships as well as the Swedish Senior National Championships 2021.
