Nokia details the Assertive Display tech on Lumia 1520, says that's the best mobile screen it's ever done

The Lumia 1520 elevates the excellent mobile displays on the Lumia range to a whole new level, thanks to the Assertive Display technology utilized, which we saw recently to be leaps and bounds ahead in terms of outdoor visibility in comparison with the iPhone 5, Xperia Z Ultra and Note 3.

We already had Nokia's High Brightness Mode and Sunlight Readability Algorithms on flagship Lumias, which could pump up an OLED display to the unprecedented 600 nits, and achieve stellar outdoor visibility, coupled with Nokia's ClearBlack filter tech.

Assertive Display, a technology developed by Apica, is a whole different approach, which adjusts the image on the screen in real time, depending on the lighting conditions and the image displayed, just as our eyes work, constantly adjusting to the environment around. "If the content on the screen is darker on the right than on the left, the pixels on each side will be stimulated differently to each other to maximize both visibility and quality," says Nokia.

That's a pretty granular level of detail we are reaching here, but the Finns also confirm that the Lumia 1520 will adjust perfectly not only outdoors, but inside too, dimming each pixel to the appropriate level. This way you won't burn your retinas when you have to check on something in the middle of the night while in bed, for instance. Nokia has chosen to place this technology in a rather niche phablet device like the Lumia 1520, but we hope to see it in future flagships too, now that the future is so closely tied with Microsoft's Windows Phone efforts.

Note 3 can hit 660 nits in automatic mode (as evidenced by the Display Mate professional display review site ), and has a near flawless color reproduction. Also, a far superior contrast in comparison to this screen due to OLED technology. GSMArena measured Lumia 1520' screen and came out with a near average readings for black level and overall contrast.

Brightness isnt the only factor in sunlight visibility/readability. There are many factors that need to come into account, like type of glass, type of display, way the screen has been bonded, how much colour/light can transmit through the glass etc.

..also, that comparison test was done without the adapt display enabled on the Note 3, revealing a typical Nokia attempt of unfair promotion and cheap shots on the competition. The adapt display does basically the same thing with supercharging the screen brightness under the sun, and really dimming it significantly beyond the lowest manual brightness(confirmed by me) in dark rooms.. the only difference is Samsung is not yelling from the hilltops about it.

You neglected to mention that the Note 3 is available on more than just AT&T in the U.S. Which is why the Note 3 will outsell the L1520.

I just wish Nokia made phones with android on them. I'm not willing to change my e-mail and music over to microsoft. I also don't want to be the last of my friends to get cool apps, even with using android I have to wait a while.

"I'm not willing to change my e-mail and music over to microsoft." - Why would you have to change that if you're switching to WP?
