Bridgestone's super-thin e-paper adds luminance

Alexander Turcic · 05-24-2007, 06:08 PM

Everyone is working on flexible paper-like displays these days, and this also includes Japanese tire manufacturer Bridgestone. The company hit the newswire today with an updated version of their quick-response liquid-powder display (QR-LPD) technology. According to Tech-On, the latest version is twice as bright as earlier prototypes thanks to special color filters developed exclusively for e-paper.

Quote:

Bridgestone intends to expand its product lines and reinforce the supply system in order to start full-fledged e-paper business. To satisfy diversified needs, the company has prepared four types of monochrome models with sizes including A7, A5, A4 and A3 for evaluation. Three models with sizes of A7, A5, and A4 are on display at the SID exhibition.

Despite what the photos suggest, Bridgestone's current e-paper (which can be as thin as thin as 290 µm) is still black and white, with the possibility to add tints of color to partial areas of the screen. Full color is on the roadmap, but not before 2008 (Heise).

The displays in the attached pic seem pretty good, as far as one can tell from pictures of this stuff, anyway.

I have some like that, myself. Bridgestone does not use E-Ink film. The LPL and Samsung demo units do.

It's a race to see who can deliver the best looking electrophoretic displays in the highest volume.

Hope to get a test sample, soon. Been waiting more than half a year.

Is the A5 resolution in the thumbnail image a typo? It says 320x480 VGA. Even if this is actually 480x640 VGA it is still significantly fewer PPI than the E-Ink 6" SVGA displays.

Wallcraft, the application is digital signage so it won't be read up close. The resolution isn't that bad from half a meter away. I suspect the typo is in calling it "VGA" when, in fact, it's HVGA, or half-VGA.
