The new eInk Pearl vs. the Old [Picture]

[TallMomof2]

I have both DX models and I could tell immediately upon unboxing mine last night that the contrast was significantly improved. The text is noticeably darker and it's really noticeable on the "screensavers". Comparing the two DXs side by side with the bezels covered you can see that the background is a lighter gray and the text much darker.

My eyes are grateful.

Frankly the first thing I did with my white K2 was to buy a dark background skin for it which made it much easier to read. I hated the dark grey background and thought that it Didnt looked like any newspaper as was claimed by amazon. I was glad to finally sell and get my iPad for reading both ebooks and Internet browsing.

I concur. There is significant improvement and it's a joy to read - anywhere and for extended periods. Love e-ink.

No desire to read on any LCD device!

I'll wait now for this improvement in the next 6" Kindle. Thanks!

Here in our office, all eyes are seeing significantly darker blacks but the background is just barely whiter.

On the Amazon forum there's a post where a fellow took it to a new and useful level and measured the display with a Datacolor Spectrocolorimeter (he inlcudes comparison with printed matter and the old DX). His findings show the blacks are quite a bit darker (nearing trade paperback print which is impressive) while the background is just a bit lighter.

He posted:
"Some reflectivity measurements:

Old (white) Kindle DX (6 months old):
white area density = 0.46, Lab = (65.8,-2.3,0.6)
black area density = 1.30, Lab = (26.6,-1.0,-2.2)
contrast in density = 0.84, contrast in lightness = 39.2

New (graphite) Kindle DX:
white area density = 0.42, Lab = (68.2,-2.4,0.9)
black area density = 1.58, Lab = (18.5,-0.1,-3.6)
contrast in density = 1.16, contrast in lightness = 49.7


trade paper: ink = 1.69, paper = 0.07 (contrast = 1.62)
new pulp: ink = 0.87, paper = 0.19 (contrast = 0.68)
old pulp: ink = 0.79, paper = 0.24 (contrast = 0.55)

I used a Datacolor Spectrocolorimeter model 1005. "Lab" is a color space measurement; the "L" stands for lightness--it matches the number on the box when you buy copier paper."

Well to my eyes the contrast is greatly improved - the blacks look much darker and sharper. Quite an upgrade.

That's some nice information, and pretty handy, and seems to mesh with what most people have been saying. I wonder what was displayed in the test. I suppose to get an accurate measure, a pre-made page of half-white, half-black would be ideal.

As I said earlier...darker blacks would make for interesting close-up photos, if anyone can get around to taking them. It'd be nice to see what is actually going on at the capsule size.

Now lets hope that the new screens will spread fast among other manufacturers, I would love to improve the contrast, but Kindle is not an option for me

[nashira]

Kindle is an option for me, but I simply don't want one... maybe Pocketbook or Sony.

I'm still waiting for Sony to bring the current ones to Australia though. Sigh.
