LCD writing tablet / eWriter is a kind of electronic device that uses high tech flexible liquid crystal technology to display words, patterns and graphics by pressure. You can write or draw with gentle pressure. The writing pad is extremely low power consumption; it only uses power when you erase the screen. A button battery can last for 1 year, you can repeatedly erase the screen for over 5000~10000 time per battery, that is equal to help save 5000~10000 papers (one tree). It is convenient, needn’t a chalk or pen, clean by pressing a button, light weight, portable, ultra-low energy consumption and eye protection.
 
This paperless LCD writing tablet is perfect for leaving messages, sketching ideas, and practicing anything from handwriting to calculus without killing a single tree.
 
The standard stylus isn't the only tool you can use to write on the Umisi Board, either. Anything from a finger to a stiff brush to a cookie cutter can be used to light up the pressure-sensitive surface. If you or your geekling are personally responsible for the death of forests worth of trees per year, consider the environmental impact of having one totally renewable Umisi Board. The LCD display lasts for at least 100,000 erasures, which is a whole lot of doodling and noting. Save a tree,
