The full form of TFT in Computer Language is Thin Film Transfer. It is a LCD flat-panel display screen.
Who invented TFT?
TFT was invented in 1973 at Westinghouse Research Laboratories. But the idea was first conceived by Bernard Lechner of RCA Laboratories and was presented at a press conference in 1968.
What does TFT do?
A liquid crystal display (LCD) uses TFT technologies to image qualities and is used in a variety of devices such as TVs, Computer monitors, mobile phones and other smart devices, navigations system, projectors etc.
TFT displays has transistors made from thin films of Amorphous silicon deposited on a glass that serves as a control valve to provide appropriate amount of electricity into the LCD for individual sub-pixel.

How does TFT work?
A TFT LCD incorporates a liquid layer between a glass substrate shaped with TFTs and color filter (RGB), clear picture element electrodes and clear counter electrodes.
Every picture element in an energetic matrix is paired with a semiconductor unit that has electrical condenser which supplies every sub-pixel the flexibility to retain its charge, rather than requiring Associate in Nursing electrical charge sent on every occasion it required to be modified, it implies that TFT LCD displays area unit additional responsive.
What are the different types of TFT?
- Twisted nematic (TN)
- In-plane switching (IPS)
- Advanced fringe field switching (AFFS)
- Multi-domain vertical alignment (MVA)
- Patterned vertical alignment (PVA)
- Advanced super view (ASV)
- Plane line switching (PLS)
- TFT dual-transistor pixel (DTP) or cell technology.
What are the differences between TFT and IPS?
- TFT displays are cheaper than IPS displays around 30-50%.
- TFT display has a response time of 10 milliseconds whereas IPS has 0.3 milliseconds.
