Flexible collaboration for workplaces and learning environments

Designed for professional collaboration and engaging interactive experiences, the Sharp LB3 Series combines powerful Android performance with flexible connectivity and highly responsive touch interaction. Featuring an Android 14 System on Chip with Google EDLA certification, the display provides secure access to the Google Play Store and seamless integration with Google Workspace apps for efficient teamwork in meeting rooms and classrooms.

The Sharp LB3 Series enhances collaboration with a natural Pen-on-Paper writing experience, built-in whiteboard and wireless screen sharing via EShare. A single USB-C connection supports BYOM workflows and up to 100W power delivery, enabling simple and clutter-free meeting setups.

With its high brightness panel, anti-glare coating and zero-bonded glass, content remains clear and readable even in bright environments. Multiple user interface options, extensive customisation features and a clean narrow-bezel design make the LB3 Series a versatile solution for corporate meeting spaces, higher education and interactive signage applications.
