At the currently ongoing SID Display Week show, E Ink and Epson have been showing a jointly-developed e-paper display. The panel sets a record in terms of resolution for e-paper screens, with a 2400x1650 resolution in a 9.68-inch screen. At 300 pixels per inch, it compares favorably to the 160PPI displays of current devices.
E ink will produce the screen, while Epson will make the high-speed display controller. It will be used for e-paper tablets that have to display large amounts of data and countries that rely on character-based text, such as Japan and China. Epson's fast processor will also provide the faster page navigation and more advanced user interfaces for more advanced e-paper readers.
When the first devices using this display and controller will reach the market hasn't been revealed.
