This year's Integrated Systems Europe (ISE) in Barcelona impressively demonstrated the rapid development in the field of display technologies and their connection with artificial intelligence. Visitors could experience innovations in the areas of LED technology, immersive experiences, and AI-supported interaction.
A dominant theme of the trade fair was Direct-View LED displays. These modular systems enable seamless screens in almost any size. The trend is towards ever finer pixel pitches in the range of 1 to 1.5 millimeters to achieve even higher image quality. In addition to the giant displays for outdoor use, manufacturers also presented all-in-one solutions with mini and micro-LED technology for conference rooms. Compared to classic projectors, these displays offer significantly better black level performance and are less susceptible to ambient light, which significantly improves image quality, especially in bright rooms.
Another highlight were transparent and flexible LED displays. These open up new possibilities for creative design and architectural integration. For example, visitors could marvel at an animated waterfall realized with transparent, flexible LED nets.
In the field of digital signage, the goal is to attract and hold the attention of viewers. To counteract so-called "display blindness," more and more companies are relying on personalized content and interactive elements. Artificial intelligence and large language models play a decisive role in this.
One example of this is the "digital humans" from Pantheon Lab. These photorealistic, interactive avatars can be integrated into signage systems and, for example, provide information at airports or shopping malls, take orders, or process payments. The combination of cloud AI and edge computing enables fast and fluid interaction.
So-called proactive AI agents are groundbreaking. These systems are able to independently perform actions and proactively offer support to users. For example, an AI-supported information system at a subway station could not only display the desired connection, but also suggest a nearby restaurant and make a table reservation.
The topic of immersion is playing an increasingly important role in the field of video conferencing and events. The goal is to give participants the feeling that they are interacting directly with each other despite spatial separation. Modern conference systems use AI algorithms to identify and automatically track the speakers. Using 3D technology and virtual reality glasses, the virtual presence of the participants can be further enhanced.
Google presented an impressive example of immersive video conferencing with Project Starline. The system uses multiple cameras and an autostereoscopic 3D display to create a three-dimensional representation of the interlocutor, giving the impression that they are sitting directly opposite.
In addition to the energy-intensive LED displays, some manufacturers also presented e-paper solutions. These reflective displays only require power for image changes and are therefore particularly suitable for static content such as advertising posters or timetables. The technology has made great strides in recent years and now also offers color displays in larger formats.
ISE 2025 offered a comprehensive overview of current trends and innovations in the field of display technologies and the integration of artificial intelligence. From giant LED walls to interactive avatars and immersive conference systems – the trade fair showed what the future of visual communication could look like.
