TFT (Thin-Film-Transistor) is an active matrix screen technology, which is more expensive than monochrome LCD but has a sharper image.

What is a TFT LCD Display?

TFT (Thin-Film-Transistor) Liquid Crystal Display is a small display type, where a transistor is embedded into each crystal gate; these transistors are then printed on thin-transparent film. 

Also designed in the late 1980s, TFT display technologies are just another variation of LCDs that offer more fantastic colour, contrast, and response times than available passive matrix LCDs.

Understanding TFT LCD

The word TFT means Thin-Film-Translator. It is the technology that is used in LCD or Crystal Display. Here you should know that this kind of LCDs is categorically referred to as active-matrix LCDs. These LCDs will hold back some pixels while using different pixels. TFT LCDs have capacitors and transistors. These two elements are crucial in ensuring that the display monitor functions using minimal energy without running out of operation.

Characteristics of TFT Display Technologies

TFT Liquid crystal display products are diversified, convenient and versatile, simple to keep up, upgrade, update, long service life, and have many alternative characteristics.

The display range covers the appliance range of all displays from one to forty inches and, therefore, the giant projection plane could be a large display terminal.

(1)High-resolution display

Display quality from the most straightforward monochrome character graphics to high resolution, high colour fidelity, high brightness, high contrast, the high response speed of various specifications of the video display models.

(2)Good Environmental Protection

The raw materials of the display screen have good environmental protection

In particular, the emergence of TFT LCD electronic books and periodicals will bring humans into the era of paperless offices and paperless printing, triggering a revolution in the civilized way of human learning, dissemination, and recording.

(3)Wide Application Range

It can be generally used in the temperature range from -20℃ to +50℃, and the temperature-hardened TFT LCD can operate at low temperatures up to -80 ℃. It can be used as a mobile terminal display or desktop terminal display and can be used as a large screen projection TV, which is a full-size video display terminal with excellent performance.

(4)Mature Manufacturing Technology

The manufacturing technology has a high degree of automation and sound characteristics of large-scale industrial production. TFT LCD industry technology is mature, with a more than 90% mass production rate.

(5)TFT LCD is Simple to Be Integrated and Updated

It is an ideal combination of large-scale semiconductor integrated circuit technology and light source technology and has good potential for more development. 

(6)Good Display Screen Effect

From the beginning of flat glass plates, its display effect is flat right angles, letting a person have a refreshing feeling. LCDs are simple to achieve high resolution on small screens.

Let me explain. As you can see, TFT has an excellent colour display and clarity.

In a TFT screen, the structure of the crystals leads to angular retardation within the light-weight. 

Features Of TFT Display

Before we go into the differences, let’s talk about the features of each technology. First, it’s interesting to discover that the TFT display technologies are the most common colour display technology; more monochrome displays still out-sell colour due to lower cost and lower power consumption. However, the limited poor visibility of TFTs in direct sunlight is their downside; but I’m getting ahead of myself here.

TFT display technologies have developed and become quite popular in tech circles.

The features offered with this advancing technology are:

1. Superior colour display – for technology that requires it or for consumers that desire colour screens

2. Not only is the colour superb, but the clarity is outstanding.

3. Features an extended half-life (half-life is that the amount of time in hours before the show is 50% as bright as once it was 1st turned on) than OLEDs and comes in variable sizes, from below an in up to over 15 inches

4. Capacitive Touchscreen or bit panel that is within the majority of Smartphones and permits for additional functionality, specifically for zooming and scrolling.

5. Resistive touch panels which are lower in cost and are usually standard on most TFT devices

6. Aspect ratio control refers to a screen’s ability to keep up a side ratio of a source image at the hardware level, and 1:1 pixel mapping is used to literally “map” the exact number of pixels specifically within the supply resolution to pixels on the screen.

7. No “ghosting” (ghosting is once a picture can stay for a brief time when instead it ought to be off)

8. Variety of displays, which may be interfaced through a range of bus sorts, as well as 18 and 24 bit for red/green/blue, LVDS, and 8 bit and 16 bit for a CPU – several controllers allow for two or a lot of different types of interfaces on the constant TFT screen.

Let me explain. As you can see, TFT has an excellent colour display and clarity.

Advantages & Disadvantages of TFT For Use In LCD Displays

We’ve been talking mainly about Smartphone screens, but since both technologies work on smaller screens, such as clocks and timers or digital thermometers, let’s focus on those.

Advantages Of TFT Display Technologies

Steve Jobs said it best: “Design is not just what it looks like and feels like. Design is how it works.” I tend to agree with him. With TFT display technologies, less energy consumption is a big deal, especially when dealing with more giant screens, and of course, less electricity means lower cost overall. The visibility is sharper, which means no geometric distortion, good for these tired, old eyes. The response time and physical style of the screens are appealing. TFT displays may save space and be placed virtually anywhere in an office or home because of the brightly lit feature and crisp, clear images.

Disadvantages Of TFT Display Technologies

Some cons of TFT screens deal with the viewing angle, which creates distortion, resulting in a less-than-perfect image. The static resolution, meaning the resolution can’t be changed, may also cause a problem, but newer models have tackled that issue. The accuracy of the display of colours is not perfect, specifically solid blacks and bright whites, so when printing an image, it may not display the spectrum of colours.

TFT Displays: Pros 

1.The best thing about TFT technology is that it uses much less energy to function when operated from a bigger screen. It ensures that the cost of electricity is reduced, which is a beautiful plus point.

2.It creates sharp images with no problems for older and tired eyes.

3.The screens made with TFT technology have a beautiful physical design and appearance.

TFT Displays: Cons

1.One of the significant problems of TFT technology is that it fails to create a wider angle of view. 

2.When the TFT screen is used for printing images, the technology fails to show the exact colours as it is there in the actual pictures.

Final Words

And there you have it. In the future, even this superb technology will change, and new, more exciting technology will take its place. You don’t want to miss it.
