Seiko Epson Corp unveiled a 13.4-inch (A4-size) electronic paper at SID 2008, an exhibition taking place in Los Angeles, the US. Its pixel count is 3104 × 4128 and definition is as high as 385ppi. Before this announcement, the company's largest electronic paper was a 7.1-inch type.
With this prototype, Seiko Epson considers that the company entered the final stage of replacing traditional papers with electronic papers.
"A4 is the normal size of documents," the company said. "If electronic papers are used in place of papers, they need a certain degree of definition. In that sense, this prototype enables us to test, in earnest, the feasibility of replacing papers."
Seiko Epson plans to conduct a market research, aiming at commercializing the new electronic paper. Though the company has not decided the time of commercialization or the forms of final products yet, it will develop final products by itself at first. The company, however, is considering selling electronic papers in the future.
The new electronic paper was developed by combining electrophoretic electronic ink of E Ink Corp and a low-temperature polycrystal Si-TFT of Seiko Epson. The TFT was formed on a glass substrate. Its contrast ratio is 10:1 and reflectance is 40%.
