NEC shows tileable A3 e-paper sheet
Eight rolls, one picture
NEC has unrolled a new form of e-paper sheet that extends to A3 in size and, it claimed, makes for an easier read than printed newspapers.

NEC's A3 e-paper: easier to read than a newspaper
The Japanese giant's electronic paper has a contrast ratio of 10:1, which may not sound much - TVs can do well beyond 10,000:1 - but is impressive for a small-scale monochrome LCD. The panel an display 16 shades of grey.
The A3 'sheet' has a resolution of 1600 x 1200 and a diagonal dimension of 19.4in - A3 is 395.2 x 296.4mm - so it has a pixel density of 101dpi.

Also available in A4
The panel uses the black- and white-coloured charged particles developed by E Ink. The particles sit inside transparent "microcapsules" - depending on whether you apply a positive or negative voltage to it, it shows up as white or black. Adjusting the voltage gives a mix, yielding those 16 shade of grey.
NEC said its sheet is suspended in a frame that's just 1mm-thick at the edges - making, the company claimed - the technology suitable for multi-panel displays. Indeed, the product comes with a controller capable of driving seven other panels.
In addition to the A3 sheet, NEC has produced an A4 version of the same resolution. Both are essentially prototypes - NEC didn't say when it'll be commercialising the sheets.

"diagonal dimension of 19.4in - A3 is 395.2 x 296.4mm"
i.e. A3 is 494mm diagonally, or 19.45 inches.
This has been a public service information announcement.
tileable?
when you say tileable? and the controller can drive another seven screens? do you mean you put two A4 side by side to get an A3? and say 4xA4 for an A2 or even 8xA4 (1 master + 7) tiled to give A1? all via a new edge contact connector?
Or does it mean something else??
