Bridgestone A3 4096 Color QR-LPD Display

adinb · 10-20-2007, 09:34 PM

Looking through Newlaunches.com I just noticed some pictures of Bridgestone's new A3 4096-color e-paper display. Only 80 DPI though.

Quote:

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.

More pictures at the original article here.

The colors look rather dull and muted.

80 DPI isn't so bad when you have that many colors to choose from per pixel, but I wonder how much power it draws?

And what is .2 mini seconds anyway? :-) are there 10 mini seconds in a maxi second?

80DPI is old CRT (72DPI) and it causes a lot of eyestrain. There was a demo at Almaden Research labs of an IBM 300DPI e-ink type display that was simply gorgeous, you could absolutely not tell it from paper.

That being said, if the panel has a gamut of 4096 colors at 80 DPI, I wonder what its DPI is at 2 colors? Probably not 16 x 80dpi but even at 4x it would be stellar.

I was just wondering how long a "mini second" was

. I would guess that it's probably a typo for "millisecond".

It's pretty smallish compared to a regular second and very much so compared to a maxi second.

It compares pretty much to my attention span.

Does this display remind you when colo(u)r LCD came out? Eink looks aiming towards computer markets.

Hard to be sure, but there may have been some glare involved.

...okay, a LOT of glare involved...

Like a spotlight was shining on it.

I wouldn't judge the quality by the photo at all, lots of stuff can go wrong, the entire photo looks bad.

As to the device. I will need to get a bigger bag and much longer arms. My arms are already getting shorter and shorter as I get older.

Perhaps it could replace coffee table books. Think how much that will wind up people who are attached to dead tree books

And here I was thinking, "It's great for ads, but not much else at that size!" You're right, it could work for coffee-table books (just a bit smaller, I think). Imagine people keeping all of their coffee-table books on such a device, with a "display page" that showed thumbnail covers of each book, or rotated through full-size covers! That's a Sharper Image gadget, if I ever heard one.

I'd like to have one to spread out pages of code on, so I can see more than one page at a time.

It'd be nice for some of the magazines I read, too, like Lapidary Journal.
