TFT: Thin Film Transistor

TFT is an abbreviation of Thin Film Transistor. It is a unique type of metal oxide semiconductor field-effect transistor (MOSFET) prepared by setting down thin films of an active semiconductor layer as well as the dielectric layer and metallic links over a sustaining however non-conducting substrate. It is a technology of display screen used in liquid crystal display (LCD). TFTs are the dynamic fundamentals that operate as switches used to turn each pixel on and off. These are completed through the use of a broad range of semiconductor materials like silicon.

In TFT, the number of one to four transistors manages every pixel. Amid all the flat-panel methods, the TFT technology is recognized for its finest resolution, however it is also the most overpriced technology. TFT screens use a transistor at every pixel, which is given in the form of matrix and this is the reason it is called as active-matrix LCDs.

Application of TFT

A highly recognized application of thin-film transistors is applied in TFT LCDs, which is an execution of liquid-crystal display technology. Inside the panels on its own, transistors are implanted, which diminish the crosstalk between pixels and enhance image stability.


  • The benefit of TFT technology is the enabling of gain of place. Their dense structure and their enormously low profundity make easier their installation and it is feasible to hang on the wall.
  • The TFT displays not similar to tiles sparkle shiny and for that reason, it suggests a high level of visual comfort. In inclusion, the image continues to exist as completely stable and clear.
  • The viability of this category of TFT screens is significant and their power consumption is low.
  • In comparison to conventional CRT screens, heat release is very low, the identical electromagnetic emissions are diminished and there is a reduction in visual fatigue.


  • Indefinite particular uses the intensity of display screen light may show inadequate.
  • The availability of very high resolutions for professional applications is rare.
  • Each day cost inclines to reduce slightly more, although it is not insignificant.
  • The transcription of colors is not always right.

These are the following major devices that use Thin Film Transistor Technology,

  • Computer monitors
  • Laptops
  • Television
  • Personal digital assistants (PDAs)
  • Smartphones
  • Video gaming systems
  • Navigation systems
  • AMOLED screens also contain a TFT layer
