Kindle 4 screen is THE SAME as K3.

[Laura81]

I'd love to see what the K3 and K4 screen look like with no border at all. Just the screens with text. The colour of the border can influence how the background and text look so take this away and see how it looks on its own. That would be a good comparison to tell if the screens really are different in any way. Well, sounds good to me anyway.

Wow okay so the bezel does come into play largely on this. I am getting me a black skin when they come out.

sorry actually i made a stupid mistake, i used K3 fonts with k4 background and vise versa... please check out the updated images in my previous post for the correct mockup.

Sony has that magic 'saturation/contrast' adjustment. I bet you could make the fonts look as bad as Nook's, by taking that down a couple of notches.

I still think the K4 in black looks better. I know it's trick of the eyes but right now I need to trick my eyes. I hope skins for the K4 comes out soon!

My K4 looks good! But all this analysis is interesting to read.

The bastards!

So, with no border at all the K4 has a lighter background and darker text... tricky, tricky eyes. It's just the black border on the K3 that makes it look lighter when it's really not.

I bought the whole "graphite enhances contrast" idea until I saw a white k3 and it doesnt look any different than my graphite.

The bevel may affect perceived lightness of the background of the device on its own, but I think if you have them side by side it's harder to fool your eyes.

It's like Tom Cruise can look big by himself, but you put him next to a 6'2 guy and he looks small. Hence, camera angles and the milk crate

In any event, if one thing looks better than another to me, I don't know if it helps to know that's just my human visual system messing with me. It's not like I'm going to replace my eyes with Terminator vision.

Of course according to Buddhism, the physical universe is an illusion, so once I accept that there is no kindle, I can stop worrying about this.

I did some colorimeter measurements of both screens (and Kindle 2 and Kindle 1 to boot as well). Here are the results: Kindle 4 vs Kindle 3 screen comparison.

To me and my colorimeter Kindle 3 and Kindle 4 screens look very similar to the point of me declaring them identical.

thanks for sharing your info, now we have few more actual measurements. And that's pretty much my conclusion as well for the 3 readers I've measured because they're all within the specifications of eInk's published spec sheet http://www.eink.com/sell_sheets/pear...ll%20sheet.pdf

I'm not sure if it's your ereaders or your measuring instrument(more likely), the "white state" lightness(screen's background) seems a bit low for both @ 64 comparing to the spec of 70. My i1 spectrophotometer shows both the K3 & K4 at about 70.

a colorimeter should work just as well depending on the quality of the RGB filters inside and its calibration tolerance. Although Datacolor is the only company I'm aware that uses a colorimeter for reflective measurement, instead of its usual emissive measurement role. On the other hand, spectrophotometers has been used for decades for both emissive & reflective measurements, so I personally trust my specto little more.

Anyway, IMO it's either your K3 & K4's eInk Pearl screens are out of spec or your spyder3print SR is not accurate. A dE of 4.8 from the spec is too large to ignore.
