E-Paper

What would an e-reader display with 600 ppi, double that of the current top-of-the-line Kindle, look like? Japan Display Inc. has offered a taste of this future, this week showcasing what it calls the world's highest resolution e-paper backplane. ​​

A few years ago, Sony released a business-focused e-paper tablet, and now the company has updated the device with higher resolution, bigger memory, NFC and Bluetooth connectivity, a new pen-friendly screen and a few bonus workflow features.

Since 2010, the Boogie Board eWriter range has provided youthful imaginations with modern-day notepads for their digital doodles and sketches. Improvements since have seen the addition of onboard storage and stylish new designs, but the latest addition to the lineup may be its biggest leap yet.
