Toppan Printing Co Launches New 42″ Digital Sign Using PlasticLogic ePaper Screens

Plastic Logic 42 inch tiled display PlasticLogic announced today that they have found a second customer who plans to manufacture signs based on PL's epaper screen tech.The new sign measures 42" diagonally and consists of 16 of PlasticLogic's 10.7" screens arranged in a a 4x4 grid. The screens have a resolution of 150ppi, giving this sign a sharpness approaching that of traditionally printed signs.

Toppan Printing Co, one of the leading Japanese companies in printing, ink, and related technologies, is going to be showing off the new digital sign at the RetailTech Japan trade show later this week.

This product is new to me, but I do know something about Toppan's past digital signage products. The general manager of Toppan's business marketing dept gave a presentation at FlexTech 2013 and he covered the signage in some detail. I was in Phoenix, AZ, in late January to attend FlexTech 2013 and luckily for you I have a copy of the slides.

Toppan has been working with E-ink since 2001. They were part of the original 3 year project that developed the first ereader to use an E-ink screen, the Sony Librie, which was released in Japan in 2004. Toppan manufactured the E-ink screen used in the Sony Librie, but that was just one of Toppan's interests; since 2001 they have also been working on large digital signs based on E-ink screens.

Toppan developed a modular sign concept that is based on assembling a grid of E-ink screen segments. The segments can be used to build a sign which is sized to fit the available space. The resolution is not nearly as high as on the ereader screen you are used to, and in fact the pixels measure 4mm on a side. But that's okay because the signs are intended to be as visible from across the room as they would be at arm's length.

Here's one sign that was installed in a Japanese rail station in 2004. If you look closely you can see the individual components that make up the sign.

Toppan's latest E-ink screen segment measures about 7.6" by 15.1". It's still based on the 4mm pixel, giving this sign a resolution of 6ppi, and it can be assembled into larger screens by arranging the segments in rows and columns.

Here's one of the new screen segments (on the left), showing both the front and the back:

The sign on the right is a prototype (developed by Hitachi) that used the now defunct Bridgestone QR-LPD  epaper screens.

Getting back to PlasticLogic, there is no news concerning when or if Toppan will release a signage product based on the PlasticLogic screen. But the current screen segment is available now in Japan and has been used to create signs that have been installed in malls, subway stations, and other public areas. It has also seen some use in trade show signs.

Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."
