TFT Full Form

The term ‘TFT’ stands for Thin Film Transistor. TFT is widely used in LCD screens to make the images look brighter. It is an active element that works in collaboration with the pixels. The image we see on the screens is made of millions of picture grids of pixels, a smaller unit of the picture. LCD screen images involve a TFT for each pixel so that the pixels can be switched off and on altogether. 

Thin Film Transistor works in an apt way that allows the screen to refresh swiftly. In other words, TFT's full meaning works as an individual switch that controls the pixels as per requirements. LCD or liquid crystal display is an up to date display technology that claims to offer crystal clear images to the viewers. With the implementation of TFT, the photos come out to look brighter and clearer.  

Who Conceived the Idea of TFT?

Bernard Lechner first presented the idea of the full meaning of TFT. He was the first person to offer the idea of running the pixels in strong collaboration with TFT technology. Bernard approached his concept at the RCA's Press conference held in 1968. He also suggested arranging the TFT in the order of the matrix. 

Why is TFT Important?

Without TFT abbreviation technology, there will be no advancement in the field of display technology. The speciality of an LCD display is the millions of pixels that work altogether. Without a Thin Film Transistor technology, you won’t be able to receive clear and sharp images. In recent times, most of the display technologies are depending on the application of TFT. 

How Does TFT Work?

TFT full meaning or Thin Film Transistor can be stated as a bundle of switches that work in coordination with the pixels in the order of the matrix. This technology mainly focuses on changing and refreshing the pixels to bring a quick change to the screen. Without this technology, the images won’t be so clear. 

What are the Key Devices that allow TFT Technology?

Several devices use Thin Film Technology. Such as,

• Smart Phones

• Computer monitors

• Video game monitors

• Television

• AMOLED screens

• PDAs or Personal Digital Assistants

• Different navigation system monitors 

• Laptops and private computer screens

How does TFT Technology benefit Human Life?

Up-to-date TFT technology is highly beneficial to the human eye. If you look at a screen with an inferior display system for a long time, it can hamper your eyesight. The images on the screen are made after assembling millions of pixels. If the pixels are not supported by any high-Quality system then it will damage your eyesight.

Definition of LCD and its Types

The LCD is abbreviated for liquid crystal display. It is a kind of flat panel display that uses liquid crystals in its primary form of operation. The invention of LCDs has led to the start of various businesses and new products. The LCD can be seen now in smartphones, televisions, instrument panels as well as computer screens.

The invention of LCD has led to the replacement of old methods of displays like gas plasma displays and light-emitting diodes(LED). Because the LCDs are designed to work to block the light rather than emit it, they consume much less power than LEDs and gas displays.

Although, as the technology is renewing itself constantly, the LCDs are now replaced by OLEDs.

The LCDs are comprised of either a passive matric or an active matrix. The active matrix is called a thin film transistor (TFT).

The Types of LCDs are:

• Twisted nematic

• In panel switching displays

• Vertical alignment panels

• Advanced fringe field switching.

The Advantages of the LCD are as Follows:

• In comparison to the CRT displays, the LCD screens are more compact, thinner and also lightweight.

• Due to the low power consumption of the LCD, very negligent heat is emitted during the operation.

• LCD consumes very little power compared to traditional modes of display. Hence, it saves energy.

• Depending upon the backlight technology, no flicker will disturb the display.

• There is no visual geometric distortion that happens.

• This doesn't emit unwanted electromagnetic radiation.

• This can be made of any shape or size depending upon the requirements.

• This can be made of very narrow borders and one can merge it with LCD screens to make it look like one huge picture for the public display.

• There is no limit to the resolution.

The Disadvantages of the LCD are as Follows:

• The uneven backlighting in some screens leads to uneven displays and distortion.

• There is a very limited viewing angle in some cheap monitors that are old. This causes a very different user experience.

• The black levels might not be as black as needed, because the LCD cannot fully block all the light.

• Display motion blur can sometimes be noted.

• Only one native resolution is available. Displaying in other resolutions may require a video scalar.

• During the manufacturing or after the use, the dead pixels or stuck pixels might occur, which leads to pixels glowing even on a fully black screen or remaining dead even when the screen is glowing.

• In high-temperature environments, it is noted that the LCD shows very little contrast.

• Even though less, but the screen display can cause eye strain in many.

• When the screen is on for a long time, thermalisation might take place leading to the screen getting discoloured in that particular area of the screen.

The LCDs are known for the Following Specifications

• Resolution

• Spatial performance

• Temporal performance

• Colour performance

• Brightness and contrast ratio

The Difference between LCDs and OLEDs

OLEDs stand for organic light-emitting diodes. In technology today, LCDs are being replaced by modern OLEDs. The LCDs are still in use. The OLEDs comprise a single panel whereas the LCDs are made up of two panels. Like an LCD, the OLEDs do not need backlighting. They are much thinner than LCDs and also are much deeper in black.

The plastic panel OLEDs can be bent and still operated. This can be seen in the new technology smartphone with curved screens.

The OLEDs seem to be more expensive than LCDs.

The QLEDs vs LCD vs OLEDs

The QLEDs are known as quantum light-emitting diodes.

The QLEDS are also known as quantum light-emitting diodes as well as quantum dot LED. The company called Samsung first developed the QLEDs and the very newer version of television sets are made of a QLED screen. These kinds of screens are usually similar to LCDs. When a quantum dot film is added to an LCD, it's called QLED, This adding a layer accounts for the improvement in the display, colour and brightness of the picture quality. The main component of QLED is small crystal semiconductor particles. These semiconductor particles can also be controlled for the output of the screen's colour.

All the three displays, that is LCD, QLED and OLEDs have their own set of advantages and disadvantages. The QLED is smaller in size, thinner as well as financially feasible compared to that of other options.
