[edit] Overview
The Epson display controller will bring greater functionality to EPDs using E Ink technology by speeding up the user interface via seamless navigation, drop down/popup menus, responsive cursors and real-time keyboard entry. The controller enables the display to perform up to 16 tasks in parallel, and supports smooth and responsive pen input devices for annotations and sketches.
Epson's controller IC's functionality is fully enabled when integrated into a display solution utilizing a host controller, tuned waveforms, and E Ink's Vizplex-enabled active matrix electrophoretic displays. Its ability to perform partial screen updates contributes to a more responsive screen for both input and output usage.
