Product description

Ultra-narrow 85-inch/86-inch double-split nano blackboard is only 5.2CM thick at the thickest part. It is formed by splicing two writing displays on the left and right. The splicing seam is 17mm. It supports ordinary chalk, dust-free chalk and various The pen writes normally. The same area not only realizes the chalk writing function of ordinary blackboards, but also provides high-definition dual-screen display and interactive touch, including various multimedia teaching functions such as playing teaching courseware, videos, pictures, animations, and annotations. The extremely narrow frame is not only twice the wide field of view, but the seamless combination of two large-size screens simplifies the traditional electronic blackboard, and combines the narrow frame attribute with the glass panel, which greatly improves the front integration of the interactive blackboard. The presentation effect of the two screens reduces the sense of separation between the two screens. The left and right interaction, the "view" window on one side and the "smart" window on the other side can achieve multi-view joint teaching and visual three-dimensional teaching in actual teaching scenarios.
