Chalk-smooth writing, minus the dust.
A flexible-LCD writing blackboard: teachers write with any firm stylus on a full-size board, strokes glow in yellow-green, and clearing takes one press. No chalk, no marker consumables, no backlight, no dust — writing itself uses no power at all.

No dust, no consumables, no backlight
Dust-free & consumable-free
Anything with a firm tip writes on the board — no ink, no chalk. Zero consumables and zero dust for teachers and students.
Eye-friendly by design
Strokes appear by natural-light reflection — no backlight, no blue light, no electromagnetic radiation, comfortable for all-day viewing.
Built like a blackboard
3H-hardness anti-glare surface, 140° viewing angle, UV-tested film that stays bubble-free and never sags, even after years of storage.
Clear the board in one press — or one block
A press-button structure clears the entire board instantly. Local erase works like a traditional eraser: infrared touch locates the area, and blocks as small as 10 × 10 mm are wiped instantly.
- One-key full-board erase
- Local erase down to a 10 × 10 mm block
- Writing keeps working during a power cut — only erase needs power
- Keeps erasing off-grid: 10 h local erase + 17 h one-key clear on a full battery
Everything on the board lands on the panel
Connected to our interactive panel, the bundled interconnection software records every stroke — students take the lesson home as a file instead of copying the board.
Live sync & split-screen
Sync mode mirrors strokes to the panel in real time; split-screen mode turns the panel into an extra board so several students answer at once.
Save & share in one tap
One key saves the board as a PDF; a QR code lets students scan the board content onto their phones via WeChat or any camera app.
Lesson recording
Screen recording with audio is built in — lessons export as MP4 files ready for the class resource library.
