Seiko Epson Corp. has developed a new display controller platform for electronic reading devices and other electronic paper products.

The platform integrates the display controller, application processor, system power management IC and firmware, combining them with the company's image processing technology originally developed for photo-quality printers.

The company claims the technology provides laser-sharp image quality of up to 300dpi and rapid refreshes. It will enable e-paper product manufacturers to speed up their time to market by allowing them to efficiently develop products with fast display refresh times and the ability to display images as sharp and clear as any produced by a laser printer. Notably, the platform will facilitate the development of products for business and education applications, which typically require higher image quality and faster displays.

E-paper devices outfitted with the display controller platform and a high-resolution e-paper display will render intricate content, such as "kanji" characters, mathematical formulas and engineering drawings, as well as illustrations, photographs and other images that require smooth gradations, much more clearly than current e-paper displays. They will also be able to flip through the pages of an e-book much faster than existing e-readers. When combined with sensors, these devices will provide powerful handwriting recognition, a critical function for business applications. The sharp improvement in readability and usability are expected to fuel the popularity of e-paper products in Japan, China, and other regions where Chinese characters are used, as well as in business and education applications where huge amounts of data have to be processed.

The company will begin shipping the platform to e-paper-based product manufacturers in April 2011.
