Today, LED displays are an innovative solution chosen and used not only by individuals, but also by companies and organisations in a wide range of sectors, from marketing and commerce to healthcare, industrial and automotive applications.

It is a revolutionary technology that, by using Light Emitting Diodes (LEDs) to illuminate pixels, has transformed the way images are perceived and content is displayed, generating an unprecedented visual experience in terms of colour, brightness, quality, contrast and uniformity from any angle.

LED screens, which have been the protagonists of an epochal change, are ready to amaze again, with new trends in the pipeline, ready to be brought to the market by companies specialising in the development, production and sale of LED technology displays, such as Macropix.

Current trends in LED technology displays

As well as differing in their use, with indoor and outdoor LED displays, there are also different types of these screens.
Among the most common and popular are Edge LEDs, with diodes positioned along the edges of an extremely thin monitor, and Full LEDs, with diodes distributed across the entire surface of the screen and LEDs for backlighting hidden behind the monitor.

These technologies are also available with a local dimming option, which, through artificial intelligence, raises contrast and perceived quality in high or low light conditions.

Perhaps less well known and used is Direct LED; this is a system with diodes on the back of the screen that ensures optimal brightness and good performance. Finally, there are the OLED displays, which do not require a backlight and use organic light-emitting diodes, ensuring more intense black tones and excellent image quality, excellent contrast, excellent brightness and perfect resolution.

Futuristic trends in LED technology displays

Among the future trends that will involve the LED display industry is the research and development of new solutions capable of imitating nature in the production of light, with ultra high resolution, energy efficient screens and curved, flexible displays. These screens are capable of mimicking the natural field of view and ensuring increasingly immersive experiences, even with the addition of interactive features such as proximity sensing, XR technologies, gesture recognition, etc.

Also the IoT will play an important role in the future of LED displays and their ability to interact in a smart way with other devices. Finally, big tech companies are increasingly looking towards Micro LED displays: these are direct emission displays in which each individual pixel (consisting of one or more tiny LEDs) emits light. These new devices not only ensure perfect brightness and fantastic colours and viewing angles, but also guarantee excellent efficiency, a very long service life and complete flexibility, to create screens that can be rolled up, folded and stretched. These features make them suitable for a wide range of uses, including emerging sectors and new digital professions.
