Two blackboards. One decision: chalk or no chalk.
The 9RIVER blackboard line covers both directions. The Smart Blackboard keeps a real writing surface — chalk and marker across the full board — with a 4K multi-touch display hidden behind sliding panels, so the room reads as a traditional classroom until you need the screen. The Dust-Free Writing Blackboard removes chalk entirely: a flexible-LCD writing surface, one-key erase, no dust and no backlight glare.
The blackboard, rebuilt around a display
Smart Blackboard
Full-board chalk and marker writing on nanotech panels that slide over a 4K multi-touch centre display. Annotation, mirroring and courseware run on the board itself.
Dust-Free Writing Blackboard
Flexible-LCD writing surface with no chalk, no dust and no backlight. One-key erase, pressure-sensitive writing and board-to-panel content sync.
Chalk vs dust-free, in plain terms
Choose Smart Blackboard when
The teaching style is board-first and the school wants one surface for chalk, marker and screen. Sliding panels close over the display so the front of room stays visually quiet, and the embedded module adds annotation and mirroring without a second screen.
Choose Dust-Free when
Dust, allergies or equipment cleanliness are the deciding factors — labs, clinics, training centres and any room where chalk residue damages instruments. Writing is pressure-sensitive, erase is a single keypress, and the board needs ≤2 W on standby.
Both share the campus stack
Same panel and module platform as our interactive flat panels, so firmware, spares and teacher training carry across a mixed deployment. Sizes and module configuration specified per classroom project.
A complete teaching computer behind the glass
The centre panel is a full interactive module, not a passive screen — courseware, mirroring and annotation all run on board.
- Android on board with Windows OPS slot for exam-board software
- Wireless screen mirroring from teacher and student devices
- Dual-pen writing with dual-colour ink for side-by-side work
- Optional camera and microphone array for hybrid lessons
