The topic of the July issue of Elektronik magazine is small OLED displays – solutions are increasingly chosen for applications that require reliability, high contrast, and compact form. At Unisystem, we know this technology well so that we can share our experiences.

In a short interview with the editorial team, Sławomir Szweda discusses key aspects of selecting OLED displays, their position among other display technologies, and Unisystem’s capabilities in delivering customized solutions – including those based on OLED technology.
If a display is needed for use in harsh environmental conditions (low or high temperatures, humidity, sunlight, etc.), how do the available options and selection criteria change?
Sławomir Szweda, CEO, Unisystem: Using a display in a demanding environment significantly affects the selection process. With OLED technology, the task is somewhat simplified – since miniature organic diodes generate the image, there’s no need for a separate backlight. The result? Excellent readability in all lighting conditions – whether in direct sunlight, shade, or indoors.
On Unisystem’s offer, you can find primarily monochromatic OLED displays with white, yellow, or blue text against a black background. These displays provide high contrast and clarity, which are crucial for delivering short messages like measurement parameters.
Many OLED models are designed to operate within a wide temperature range – from as low as -40 to as high as +80°C – making them suitable for both low and high temperatures and rapid fluctuations. When properly protected, their compact construction also ensures resistance to dust, moisture, shocks, and vibrations. As a result, OLED displays are well-suited for mobile and stationary devices operating in harsh environments.
For many years, OLED display prices were significantly higher than those of LCD-TFT. What does the comparison look like today, assuming two typical and similar 5-inch solutions?
OLED displays still tend to be more expensive than LCD-based solutions, but the gap has narrowed considerably compared to a few years ago. Unisystem’s offer includes monochromatic OLED displays typically up to around 5.5 inches. Comparing them with monochromatic LCDs is more accurate – they are often similar in size and used in comparable applications.
The higher price of OLED displays is well justified for projects in which high contrast, wide viewing angles, or low power consumption are critical. In many cases, OLED technology offers an optimal solution – both in terms of functionality and value for money.
What level of technical support is considered standard today? What can you offer in this regard?
Delivering a component is just the beginning. Increasingly, full technical support throughout the project lifecycle is becoming the norm – from initial consulting and component selection to hardware and software integration to post-sales support. At Unisystem, we offer this comprehensive approach.
Our Solution department works closely with customers to design complete modules, combining a display, touch panel, industrial computer, and additional components such as scanners. This approach enables us to deliver ready-to-integrate solutions tailored to the specific application and working environment.
