The core features of this High-End Nano-Touch Smart Blackboard focus on premium performance, durability, and advanced functionality. First, the patented nano-coating touch technology replaces traditional infrared or capacitive touch sensors, creating a seamless touch surface with Mohs 7 scratch resistance. This technology ensures the panel remains clear and responsive even after 50,000 hours of continuous use, significantly reducing maintenance costs and extending device lifespan. Second, the ultra-narrow 2.5mm bezel design with 4K Ultra HD resolution provides an immersive visual experience, with a 92% screen-to-body ratio that maximizes the display area for courseware, videos, and data. Third, the cross-platform compatibility supports seamless connection with Windows, macOS, Android, and iOS devices, allowing users to cast content, control the blackboard, and collaborate in real time. The built-in whiteboard software supports 3D object display, enabling teachers to present complex scientific models or corporate designers to showcase 3D product prototypes. Moreover, the real-time cloud collaboration function allows multiple users to edit and share content simultaneously, regardless of their location. The device also supports stylus writing with 4096 levels of pressure sensitivity, providing a natural writing experience similar to traditional chalkboards.
