The Display Week 2021 Symposium Preview

Dear Friends and Colleagues, On behalf of the Society for Information Display's program committee, I am pleased to welcome you Display Week 2021, our 58th International Symposium, Seminar, Exhibition, taking place May 17 21. This year marks second virtual event. Although we are disappointed that pandemic has once again prevented us from meeting face face, be able offer a high-quality event leverages experience gained hosting last year's show. 2021 will on-demand technical content was so popular in 2020, as well new opportunities interact with friends colleagues. Like year, each day mix short courses, seminars, symposium presentations organized by subject. The features 69 sessions consisting 282 oral (approximately 98 which invited) 115 poster presentations. More than quarter submissions represent two categories: OLEDs Active-Matrix Devices, followed closely strong showing Emissive, MicroLED, Quantum-Dot category. There papers interest all areas. committee is especially despite COVID-19, have continued draw around world: For example, we're publishing 119 China, 70 U.S., 65 Korea. Each SID's team designates special topics based on latest areas progress intensity. offering presentation tracks cover technologies applications AR, VR, Mixed Reality; High-Dynamic-Range Displays; Machine Learning Internet Things (IoT) Displays. We added author interviews lineup this real time many presenters. You'll also view Exhibitors’ Forum presentations, takes specific product/technology Once again, SID making program, exhibits, panels, etc., available registered users four months after Week—there plenty take like. Outside there are, course, other events enjoy at Week. hope some intriguing demos exhibit floor, example. You may check out much-anticipated keynote sessions, feature five speakers year. Women Technology panel CEO returning, another important highlight, Business Conference, offers expert discussion forecasts key industry markets. Your enthusiastic participation always been Week's success. sincerely look forward seeing conference show floor May.
