Why We Love TFT Displays (And You Should, Too!)

Thin-film transistors (TFT) have revolutionized the way people view and experience moving images on a display, and are now a ubiquitous part of our technological experiences. They are best known for being implemented in active-matrix Liquid Crystal Display (LCD) systems, which offer numerous benefits over other LCD designs on the market. That might be why TFTs have now found their way across a broad array of industries, and increasingly represent the industry standard. Here is information about how industries are utilizing TFTs, why they're superior to other LCD displays, and how they work to deliver the best image possible.

what industries are using tft displays?

TFTs are extremely popular within the consumer electronics industry. They are seen in mobile phones and flat-screen televisions, and are now the primary technology for computer screens, too. However, there are many other industries that use them. Here are some examples of where they're used:

             Medical equipment


             Navigation systems

             Engineering products

             Military vehicles


             Video games

What Are TFTs Used For?

TFT displays are used to display sharp images in a variety of different configurations. In the medical industry, TFT panels are used in digital radiography equipment and heart monitors. In the automobile industry, TFT displays are seen in cars' instrument-control panels. Their implementation allows drivers to customize these panels, and offers crystal clear displays in a digital format.

TFT displays are also used to produce vivid displays for handheld video game companies. They can also be seen in GPS devices, radio interfaces and even in the cockpits of commercial airliners. Ultimately, they're seen in just about any setting where a manufacturer, engineer or optoelectronic designer wants to provide a clear and versatile viewing experience to the consumer the product is being designed for.

Exploring the Past and Predicting the Future of TFTs

TFTs first began being used widely in TV monitors and computers around 2008. Many of them now use hybrid LCD-TFT displays, which means TFTs essentially dominate the consumer electronics industry. However, as described above, TFTs are making their way into a broad array of industries and their use is expected to grow. In the future, TFT displays may be seen in a variety of smart home electronic devices; used in digital wearable devices like smart watches and activity monitors; and found inside the displays of construction equipment.

However, one of the most innovative areas for which TFTs are being used is in flexible displays, which may have a wide variety of applications, including smart bandages, security sensors, radiation detectors and innovative new display designs.

Why Choose A TFT?

TFTs have a number of benefits that help explain their wide array of applications. One of the main reasons is their ability to concentrate more pixels, helping to create a higher resolution than other LCD displays. They also use far less energy than other LCD technologies, helping to save energy costs. Furthermore, TFTs are known to produce a brighter image than other LCD technologies, an important factor that can improve the quality of images and the overall user experience.

Another added benefit that many designers find important is the fact that TFT works extremely well in sunlight, which helps prevent glare. Automobile companies, for example, might find this important if they want to ensure their displays are clear on a bright, sunny day -- an important factor for driving safety and comfort.


How Do TFTs Work?

Thin Film Transistor (TFT) displays create a moving image through an electrical and chemical process. A TFT typically utilizes a sandwich design in which liquid crystals are placed between two extremely thin plates of glass. An electrical voltage pulse manipulates the molecular structure of these tiny liquid crystals, which allows different wavelengths of light to pass through, based on the specific polarization of light. These different wavelengths create different colors and intensities in the form of minuscule dots on the TFT display, all of which adds up to create a specific image. This happens rapidly, and it refreshes quickly as well, to create a crisp and clean image based on the signal being sent to the TFT display.

An actual TFT panel has several different chemical, metallic and conductive filters within its glass panes. Although there are different configurations for different TFT panel designs, the basic design involves color filters, polarizing filters and a glass substrate. These filters work together to control the amount of light that passes through, helping to determine the colors and images that will be created.

Pixel density also has a significant impact on the detail of a TFT display, with more pixels delivering a crisper image. A typical TFT display has millions of pixel units. But unlike other technologies, TFT has a separate transistor attached to each individual pixel within a display. This brings two important benefits. For one, since each transistor is so minuscule, only a small electrical charge is necessary to generate an image. Secondly, its ability to quickly refresh allows for extremely crisp and smooth flowing images.

Backlighting gives TFTs the light they need to create specific images. But the kind of backlight is sometimes different. Older models utilize white light while newer TFTs are equipped with light-emitting diodes (LED), which reduce power usage and allow for smaller screens.

Ultimately, TFTs are an advanced fixture in technology that are continuously being developed to produce better images and offer different features. But they essentially serve as the "face" of many devices. Their applications are practically endless, which means industries will be using this cost-effective technology as a way to improve LCD displays now and long into the future.
