Interactive complex with chalk surface AlfaDispLay ADLEB-75B BlackBoard 75”
AlfaDispLay ADLEB-75B BlackBoard 75" is an interactive complex of the latest generation, combining an interactive panel and a traditional chalk board. This solution allows you to write with chalk on the entire surface of the board, including the screen of the interactive panel. This approach significantly increases the efficiency of the teaching process and meets the needs of teachers who cannot imagine a lesson without the use of a traditional chalk board. The interactive panel software has a built-in “Interactive Whiteboard” mode, which allows the teacher to use the usual functions - draw, write by hand, add geometric shapes, function graphs, etc.
