Key Features
- One-Touch Erase Button: A single button instantly clears the entire screen, allowing for immediate reuse.
- Smart Lock Function: A switch on the device allows users to lock the screen to prevent accidental deletion of important notes or drawings.
- Long Battery Life: Powered by a replaceable coin-cell battery (like a watch battery), these devices can last for months or even years (often 100,000+ erasures) because they only consume power when the screen is cleared.
- Portable & Lightweight: Typically, these devices are ultra-thin (approx. 7mm) and lightweight, making them easy to carry in bags for school, office, or travel.
- Eye Protection: As they do not use backlighting, these screens do not emit radiation or blue light, making them safe for long-term use by both children and adults.
