Display-Based Optical Wireless Communication for IoT and 6G

Dear Colleagues,

This Special Issue aims to highlight recent advances in screen/display-based optical wireless communication (OWC), a rapidly evolving subfield of visible light communication (VLC). With the proliferation of high-brightness displays, LED panels, and camera/sensor-equipped devices, display-based OWC enables data transmission through screens to photodetectors or cameras, offering low-cost, license-free, and EMI-resilient solutions. This paradigm is well-suited for emerging smart environments, human-centric interfaces, IoT networks, and secure short-range communication.

Recent progress includes modulation and coding techniques tailored for display-to-camera links, machine vision-assisted demodulation, and integration of such systems with edge AI and embedded platforms. Moreover, the synergy of OWC with intelligent surfaces, AR/VR displays, and 6G use-cases is driving new research opportunities.

This Special Issue invites original contributions and review articles that address fundamental research, novel applications, and enabling technologies in display-based OWC systems.

Topics include, but are not limited to the following:

• Display–camera communication and screen-to-sensor links;
• Visible light communication using LED displays and signage;
• Screen-based VLC for IoT and smart devices;
• Modulation, coding, and synchronization for visual MIMO and OCC;
• Integration with AR/VR, smart homes, and human-machine interfaces;
• Low-power and energy-efficient display-based transmitters;
• Channel modeling and performance evaluation;
• Display-based OWC in 6G and next-generation networks.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
