Long-term availability and easy to clean
For use in medical technology, long-term availability and security of supply are crucial for TFT displays in order to be able to supply devices for many years without recertification. Equally important are a very good display with high resolution and readability from any viewing angle, as well as hygienic cleaning of the screen. Special cover glasses and tightly mounted touch panels ensure long-term reliability in the medical environment.
EMC safe and Atex suitable
In industrial applications, TFT displays have to cope with extreme conditions. These include wide temperature ranges, direct sunlight and long-term availability for safe operation over many years. Equally important are high EMC compatibility and - if required - compliance with ATEX safety requirements for potentially explosive atmospheres. Robust design, optimized brightness and reliable readability ensure permanently safe operation even under harsh environmental conditions.
Modern and cost-effective
In smart home and building technology applications, TFT displays impress with their attractive design and good presentation at low prices, often below those of passive LCDs. Depending on where they are used, they must reliably withstand changing climatic conditions. Good readability from different viewing angles and under different lighting conditions ensures convenient operation of controls and displays.

Powerful and protected
In outdoor applications, TFT displays have to withstand extreme conditions. This includes a wide temperature range, strong UV radiation as well as IK and IP protection solutions against mechanical influences and moisture. High brightness and optimized reflection values are crucial in order to be able to read the screen clearly even in direct sunlight. This means that displays and operating units remain permanently reliable and clearly visible outdoors.
Energy-saving and environmentally friendly
Low-power TFTs with reflective or transflective technology have low power consumption, ideal for battery-powered applications. By reflecting the incident light, they remain easy to read even in sunlight without having to permanently activate the backlight. They therefore offer long running times, high energy efficiency and reliable readability under a wide range of lighting conditions.

FAQs
A TFT display (Thin Film Transistor) is a liquid crystal display in which each pixel is controlled by its own thin film transistor within an active matrix. Each pixel in turn consists of three sub-pixels (RGB). This enables high image quality, fast response times and precise color display. Compared to passive LCDs, TFTs offer clear advantages: better resolution, higher brightness and an extended viewing angle.
The resolution of a TFT determines how detailed the content is displayed. A high resolution is crucial for demanding applications, such as in medical technology or in the industrial sector. Brightness, measured in cd/m², is particularly important for outdoor applications to ensure good readability even in bright light.
Color displays can be optimally combined with touch screens. Capacitive and resistive touch panels are usually used for this purpose. In comparison, capacitive touch panels offer the advantage of precise, fast control with multi-touch support. Resistive variants are cheaper, but mechanically more sensitive. Previously preferred for glove operation, today's capacitive touchscreens also reliably recognize this. The choice depends on the application and environmental conditions.
The backlight of a TFT display can be individually adjusted to optimize brightness, colour temperature and energy efficiency. Depending on the design of the lighting, fewer LEDs can be used or they can be dimmed. The color can be optimized using pre-sorted LEDs or special films. The color curve of the TFT display can also be adjusted. This is particularly interesting for battery-operated devices.
Different interfaces are used depending on the display size and resolution: SPI and I²C are compact and suitable for smaller displays, LVDS is often used for medium to large displays, while HDMI enables fast transmission of high-resolution images.
One option is to select a manufacturer that guarantees long-term availability in order to avoid obsolescence. Alternatively, it is possible to qualify two different cells at the same time and store a minimum stock. The choice of LEDs for the backlight and the design are particularly important for the service life.
TFT displays can be equipped with different types of protection: IP protection offers protection against water and dust, while IK classes indicate resistance to mechanical impact - important for outdoor and industrial applications. We can provide you with suggestions on how the desired protection classes can be realized (e.g. with thick front glass, PMMA panes, special bonding).
Transmissive TFTs require an active backlight and offer bright colors, but are less readable in direct sunlight. Transflective TFTs combine backlighting with reflection and are suitable for changing light conditions. Reflective TFTs utilize ambient light and have very low power consumption, ideal for battery-powered applications. However, the color display is not as brilliant as that of transmissive TFTs, for example.
Customized TFT displays are often worthwhile from around 20,000 units if special dimensions, interfaces or an individual design are required. They offer clear advantages, but require higher tooling costs and longer lead times - especially compared to passive LCDs.
Standard modules, on the other hand, are available more quickly and are cheaper for small quantities - ideal for applications with short development cycles and proven requirements.
High brightness (often > 1,000 cd/m²) achieved by a higher number of LEDs, anti-reflective coatings and optical bonding are crucial for good readability in sunlight. In combination with transflective technologies, content can be displayed clearly even in strong sunlight.
Panels with IPS, TN or MVA technology differ in the alignment of the liquid crystals and therefore in their optical behavior.
- TN (Twisted Nematic): The liquid crystals twist when voltage is applied in order to control the light transmission per pixel. Advantage: very fast switching times. Disadvantage: limited viewing angles and color stability, as the light transmission changes significantly when viewed at an angle.
- IPS (In-Plane Switching): The liquid crystals rotate within the pixel plane (parallel to the substrate). This enables constant light modulation at different viewing angles. Advantages: high color accuracy, stable brightness and wide viewing angles - ideal for high-quality liquid crystal displays.
- MVA (Multi-Domain Vertical Alignment): At rest, the crystals are perpendicular to the glass surface and tilt in several directions (domains) when activated. This improves contrast and viewing angle compared to TN, with a simpler structure compared to IPS.
All technologies use thin-film transistors in an active matrix for targeted control of each pixel.
