BridgeStone show color, flexible A3/B-size EPD

Original Post from October 31st 2007.

As you may know, BridgeStone (yes, even those guys doing tires can do this stuff!) have a bi-stable electrophoretic display (EPD) technology in many ways similar to E-Ink, called "Quick Response Liquid Toner" (QRLT) that they claim is faster than E-Ink.

They are working with Hitachi in Japan to take it into signage.

At the Flat Panel Display (FPD) 2007 show recently they have shown a color (4096 colors) display of A3 (B-size) size. Don't be confused by previous photos of BridgeStone displays showing color, they were two-color (e.g. Black&White, or Red&Yellow) displays. This is the Black&White display with a color filter on top (RGB, or maybe RGBW).

"Bridgestone Japan has developed an A3 sized color electronic paper it was showcased at the FPD International 2007 exhibition held at Yokohama. The A3 sized electronic paper has a display area of 435 x 326mm and can display 4096 colors at 80dpi resolution. The display makes use of QR - LPD (Quick-Response Liquid Powder Display) which the company has been developed over the years. The charged particles repel each other delivering a response time of just 0.2 mini seconds. Apart from being the biggest the electronic paper is also the thinnest in the world at just 0.29-millimeters."

Here's an image that seems to show another version of edge on, it's VERY slim.
