A joint venture, Epson Electronics America and E Ink have developed a display controller IC that delivers unique capabilities for E Ink's Vizplex-enabled electronic paper displays. The electronic paper display controller IC, part number S1D13521B, combines technologies from both Epson and E Ink. It forecasts greater functionality by speeding up the user interface via seamless navigation, drop down/popup menus, responsive cursors, and real-time keyboard entry. The device also enables the display to perform up to 16 tasks in parallel, and supports pen-input devices for annotations and sketches. Samples of the Epson S1D13521B will be available in May and production quantities will be available in August. Sample price is $18.
