FOR ANYONE WHO ATTENDS DISPLAY WEEK, it can be quite awe-inspiring. Hundreds of talks and presentations are assigned to designated rooms and times, there is a constant buzz in the impressive exhibition area, and ideas are brimming throughout, whether in private conversations or while witnessing the possibilities in the I-Zone.

But all this innovation and magic, if you will, has a starting point, where the program chairs and general chairs, symposium coordinators, subcommittee chairs, and SID staff congregate to discuss how the pieces will fall into place.

Witnessing the paper selection process is rather fascinating. Dozens of dedicated display specialists congregate to review hundreds of papers and to discuss what topics are not only the most newsworthy or of highest interest, but also those having a large impact on the industry.

With that in mind, this article highlights some of the best work being done in display technology that will be featured at Display Week 2025 in San Jose, California, May 11–16. Although not all-encompassing, its aim is to serve as a symposium guide for meeting attendees who may feel a bit overwhelmed by all the offerings.

Several expanded focus areas will be introduced to explore the rapidly evolving developments in the display industry, which are driving groundbreaking innovations and the emergence of exciting new technologies.

This year, the technical symposium will feature a record-breaking 98 sessions organized by their technical focus.
