It is impossible not to notice how technology has developed over the past two decades, pushing our world forward. A sizable revolution has also taken place in the industrial monitor market, offering us entirely new options for displaying images and content. An example of this are the LCD-TFT displays available in the offer of our online store Unisystem. What are their advantages? How to choose an LCD-TFT display for industrial applications? We invite you to read more!

What are LCD-TFT displays?
LCD-TFT displays are modern liquid crystal displays that use specialized unipolar transistors to control the pixels. As a result, the technology enables the presentation of high-quality images with deep contrast and satisfying color intensity. This is possible because in TFT matrices as many as four transistors are assigned to each pixel, while in ordinary monochrome LCD displays it is one transistor that is responsible for an entire row of pixels. LCD-TFT displays, therefore, offering a more detailed, crisp and high-resolution image.
LCD-TFT displays are commonly used in TVs and laptops. They have also excelled in the industrial sector, where they are used as screens in machines that require precise control. They are also used in the medical industry, where the detail of the diagnostic image is of colossal importance to the process of diagnosing, treating and monitoring patients. We also use LCD-TFT displays on a daily basis, moving around in urban spaces. They are the most commonly installed in parcel machines, ATMs, parking meters, ticket machines or digital tourist information points. Our company – Unisystem – offers custom LCD-TFT displays. We work with manufacturers such as Winstar, Riverdi, Litemax, Innolux and BOE. As a result, we are able to provide your company with a monitor that is completely customized to the specifics and requirements of the industry in which you operate.
What criteria should be considered when selecting an LCD-TFT display for industrial use?
LCD-TFT in Industry. Application of LCD-TFT displays in various economic sectors
When buying an LCD-TFT display for industrial applications, pay attention to the following parameters:
- screen resolution – the higher the resolution, the more detail you can see on the screen, which translates into better quality and greater clarity of displayed content, LCD-TFT screen resolution depends on the purpose of the application;
- brightness of the display – it should be at least 1000 cd/m2, so that the image will be perfectly visible in all lighting conditions;
- Display contrast – the higher the contrast, the better the readability of the content and the more pleasing to the eye image;
- display angle – we recommend LCD-TFT displays with the widest possible display direction, as this will ensure that the image is legible and clear, regardless of the user’s position relative to the screen;
- operating temperature – to ensure reliable operation in a variety of environmental conditions, manufacturers offer displays suitable for a wide temperature range: from -30 to 80°C. Such a display will work well for both outdoor and indoor applications.
Also worth mentioning is the tightness of the housing. Displays used in industrial settings must be resistant to moisture, dust, vibration and extreme temperatures. A robust housing protects electronic components from damage, extending the life of the device. Another aspect that needs to be mentioned is the type of touch panel. He, too, must be resistant to damage, as well as sensitive to touch. If the specifics of the job require it, the user should be able to operate the touch panel with gloves without any problems.
How to adapt the LCD-TFT display to the unique industrial operating conditions?
Choose a device designed for extreme temperatures, vibration and suitable for exposure to dust, electromagnetism or moisture. Also important is the compatibility of LCD-TFT displays with selected control systems and their ability to be easily integrated into existing infrastructure. Screen size also matters. Larger screens allow more information to be displayed, which is especially important when operators need to quickly process data and make decisions based on it. The large display also makes it possible to design user interfaces in a more accessible way. Both text and icons can be made larger, allowing the display settings to be customized to suit the individual needs of the machine operator, for example.
What are the differences between LCD-TFT displays and other types of displays in industrial applications?
LCD-TFT displays are more technically advanced than standard LCD displays. As a result, they stand out with higher image quality, higher resolution and offer wider viewing angles.
Comparing LCD-TFT displays to IPS displays, it can be said that the latter have higher contrast, better color reproduction and faster response times, although here the economic aspect also comes into play, which plays an important role in the industrial sector.
OLED displays are also increasingly used in industry and business for more advanced applications. Here we are dealing with a completely different display technology from LCD screens. The OLED screen is characterized by self-luminous pixels that do not require an additional light source, such as the backlight used in traditional LCD displays. As a result, OLEDs offer deep blacks and high contrast. This also translates into better viewing angles and more intense colors compared to LCD technology. The OLED screen is also thinner and lighter, allowing for slimmer and sleeker devices. The technology also has lower energy consumption. In favor of LCD-TFT displays, however, are longer life, higher brightness and greater compatibility with existing industrial systems.
What are the advantages of LCD-TFT displays in specific industries?
Modern LCD screens are characterized by high image quality, which makes the presented content clear and easy to read in different lighting conditions. Using IPS technology, these displays offer better viewing angles and a richer color palette, which significantly improves the user’s visual experience. In addition, they are more energy efficient compared to older types of displays, resulting in lower operating costs. LCD-TFT displays are also rugged and suitable for use in a variety of often harsh environments, making them an ideal choice for industrial and commercial applications. By investing in such a solution, the company gains not only in the quality of presentation of its data, but also in lowering long-term costs and increasing operational efficiency.
