TFT Explained: How to Choose the Best Thin-Film Transistor Technology for Your Display

TFT Technology: What It Is, How It Works and How to Choose It


When you are shopping for a new display, whether it is a monitor, a TV, a tablet, or a smartphone, you may encounter the term TFT or thin-film transistor. But what does it mean and why does it matter? 

How does it affect the quality and performance of your display? And how can you tell the difference between the various types of TFT technologies available in the market today?

In this blog post, we will answer these questions and more. We will also share some tips on how to choose the best TFT technology for your display needs and preferences. So, let’s get started!

What is TFT Technology?

TFT or thin-film transistor technology is a type of LCD or liquid crystal display technology that uses thin-film transistors to control the pixels or dots that make up the image on the screen. 

TFT technology improves the image quality, brightness, contrast, color accuracy, and response time of LCD displays by providing more voltage and current to each pixel. It also reduces the power consumption and heat generation of LCD displays by switching off the pixels that are not in use.

TFT technology is widely used in various types of displays, such as monitors, TVs, tablets, smartphones, laptops, digital cameras, and more. However, not all TFT displays are created equal. 

Types of TFT Technologies

There are different types of TFT technologies that have different characteristics and advantages. Some of the most common types of TFT technologies are:

TN (Twisted Nematic)

This is the oldest and most basic type of TFT technology. It has a simple structure that consists of two polarizing filters and a layer of liquid crystals that twist when an electric field is applied. TN displays are fast, cheap, and energy-efficient, but they have poor viewing angles, color reproduction, and contrast ratio.

IPS (In-Plane Switching)

This is an advanced type of TFT technology that improves the image quality and viewing angles of TN displays by aligning the liquid crystals horizontally instead of vertically. IPS displays have wide viewing angles, accurate colors, and high contrast ratio, but they are slower, more expensive, and less energy-efficient than TN displays.

VA (Vertical Alignment)

This is another advanced type of TFT technology that improves the image quality and viewing angles of TN displays by aligning the liquid crystals vertically instead of horizontally. 

VA displays have wide viewing angles, deep blacks, and high contrast ratio, but they are slower, more expensive, and less energy-efficient than TN displays. They also suffer from color shifting and ghosting issues.

OLED (Organic Light-Emitting Diode)

This is a different type of display technology that does not use liquid crystals or backlighting at all. Instead, it uses organic compounds that emit light when an electric current is applied. 

OLED displays have excellent image quality, wide viewing angles, fast response time, low power consumption, and thin design, but they are very expensive and prone to burn-in and degradation problems.

How to Choose the Best TFT Technology for Your Display?

Choosing the best TFT technology for your display depends on several factors, such as:

Your Purpose

What do you use your display for? Different types of activities require different levels of image quality and performance. For example, if you use your display for gaming or video editing, you may want a fast and smooth display with high resolution and refresh rate. 

If you use your display for graphic design or photography, you may want an accurate and vivid display with high color gamut and contrast ratio. If you use your display for casual browsing or watching videos, you may want a balanced and comfortable display with good brightness and viewing angles.

Your Budget

How much money are you willing to spend on your display? Different types of TFT technologies have different prices depending on their features and specifications. 

Generally speaking, TN displays are the cheapest but also the lowest quality. IPS displays are the most expensive but also the highest quality. VA displays are somewhere in between. OLED displays are very expensive but also very impressive.

Your Preference

What do you like or dislike about your display? Different types of TFT technologies have different strengths and weaknesses that may appeal to some users but annoy others. 

For example, some users may prefer TN displays for their fast response time and low power consumption but dislike their poor viewing angles and color reproduction. Some users may prefer IPS displays for their wide viewing angles and accurate colors but dislike their slow response time and high power consumption. 

Some users may prefer VA displays for their deep blacks and high contrast ratio but dislike their color shifting and ghosting issues. Some users may prefer OLED displays for their excellent image quality and thin design but dislike their high price and burn-in problems.


TFT technology is an important factor to consider when buying a new display. It can affect the image quality, performance, and durability of your display. 

Therefore, you should do some research and comparison before making your final decision. You should also test the display in person if possible to see how it looks and feels in real life. We hope this blog post has helped you understand what TFT technology is and how to choose the best one for your display
