For more than 50 years, LCDs have provided visual clarity for many industries. This invention has introduced a whole slew of new devices and advancements in display technology, such as Thin-Film Transistor (TFT) displays.

TFT displays have changed the game with brighter and sharper images than common LCDs. While LCDs have their place in the industry, especially in low-power environments, TFTs are often in use where high-quality images with a range of colors and hues matter more.

Selecting the right LCD for your business is important to achieve what you need as efficiently as possible.

Is a customizable TFT LCD right for you? Find out about this innovative display technology and its many applications. 

Understanding TFT Screens

A TFT screen essentially consists of tiny transistors and liquid crystal cells. While both use liquid crystals to produce images, we could say that TFT screens are a refined version of LCD technology.

The transistors that TFT LCDs have act as switches, which control the flow of electrical current through each liquid crystal cell. Unlike older displays, what’s great about TFT displays is that they can precisely control the brightness and color of each pixel, allowing engineers to design using various TFT display interface technologies

When electricity flows through a transistor, it changes the alignment of liquid crystals in a cell, affecting how light passes through. By adjusting the voltage to each transistor, TFT displays can produce a wide range of colors and shades. This is why TFT screens can produce such detailed images.

TFT screens combine precise engineering and visual quality to provide an immersive viewing experience.

Customizable TFT Display Options 

We can configure TFT displays in many ways. Here are the most common solutions we offer:

  • Size, Shape, and Resolution: In need of a screen that fits just right? TFT displays can come in various dimensions. This makes them so adaptable for anything that you need. It should be noted that with these customization options, there is usually an MOQ of at least 100,000, and NRE charges may apply as well.
  • Touchscreen Capability: Make your display interactive by including a touchscreen. In general, touchscreen technology can enhance the user experience and overall accessibility.
  • Brightness: Make your display visible in the sunlight. Whether it’s indoors, outdoors, or in low light, customizable brightness settings deliver the best possible visibility.
  • Interface Options: Connect seamlessly with other devices. Choose from a range of interface options like HDMI, MIPI DSI, LVDS, TTL, RGB and SPI to suit your connectivity needs.
  • Specialized Coatings: Apply coatings like anti-glare or anti-fingerprint to improve visibility and durability. This keeps your screen looking sharp.
  • Mounting Features: Integrate your TFT display into the enclosure by incorporating mounting features for a durable solution that is easily assembled on your production line.
  • Cover Glass and Lens:  One of the most highly customized components on a TFT, the cover glass can be modified to fit your product, whether you need a unique size, shape, hardness, or printing, the cover glass can be adapted to fit your application.  For more information, a detailed resource on the customization of the cover glass can be found here.

Being able to customize TFT displays opens up a world of possibilities – catering to specific needs and preferences. 

Common TFT LCD Applications

You might not realize it, but TFT LCDs are all around us. Here are some of the ways you can make use of small TFTs for your business:

  • Smartphones and Tablets: These displays bring your phones and tablets to life. They provide the flexibility to bring apps, videos, and interfaces sharper and with vibrant colors.
  • Agricultural Machinery: From tractors and combines to and seeders and fertilizer spreaders, TFT LCD screens are the go-to choice for displaying everything from GPS information to machinery controls.
  • Manufacturing Production Line Machinery: Many manufacturing lines use equipment containing TFTs to display vital information about the health of the machine and the process it is completing.
  • Aerospace Displays: TFT screens are also the perfect fit for HUDs in planes and shuttles.
  • Car Dashboards: With TFTs, you can display car dashboards that show speed, fuel level, and navigation directions in style.
  • Mining Devices: Whether on the surface or underground, TFT displays are found in a variety of mining equipment including ground penetrating radar devices and underground mining drone user interface devices.
  • Medical Devices: Small TFT LCD screens play a key role in patient monitoring equipment, providing doctors and nurses with real-time data and diagnostics.
  • Handheld Test and Measurement Equipment: Engineers and technicians rely on small TFT LCD screens for on-the-spot analysis and troubleshooting in fields like electronics, telecommunications, and more.

With these many applications, you can tailor TFT displays to guarantee optimal performance and user satisfaction for your business.

Factors to Consider When Choosing TFT Displays

There are some fundamental points to keep in mind when it comes to picking the perfect TFT display for your project or product:

  • Resolution: Higher resolutions mean sharper images and text, so consider the resolution that best suits your needs.
  • Size: Choose a screen size that fits your requirements. Think about where your display will be used and how much screen space you have available for your product.
  • Viewing Capability: Think about how and where your display will be viewed. Displays with wider viewing angles and with high brightness/contrast can make sure that your content looks good from all angles and environments. 
  • Durability: Will your display be exposed to harsh conditions? Will it be used frequently? Consider factors like scratch resistance, impact resistance, and temperature tolerance so that your screen continues to work for a long time.
  • Power Consumption: This is a factor especially relevant for battery-powered devices. Consider going for a transflective TFT display to maximize battery life and minimize operating costs.

With these factors, you can choose and customize a TFT display that meets your needs and exceeds your expectations.
