When the HTC One X arrived earlier in the year, it easily took the smartphone display crown, blowing us away with its high pixel density and super-clear zero-air-gap screen. Fast forward six months and we already have a successor in waiting, in the form of Verizon's Droid DNA. The DNA rocks a 1080p SuperLCD 3 screen versus the One X's 720p SuperLCD 2, and that means it boasts a whopping 440 ppi (pixels per inch) compared to the One X's 312.

It shouldn't be surprising to hear that the Droid DNA produces incredibly crisp images -- after all, it matches the pixel count of the average HDTV.  But the One X's screen is impressive in its own right, despite packing less than half as many pixels in total. As you can see in our close-up shot above, the differences between the Droid DNA and One X are noticeable but subtle -- when viewed up-close, icons, text and other on-screen elements do appear crisper. The perceived difference isn't anywhere near as great as going from WVGA to 720p, though.

Pixels aside, the two phones are pretty closely matched in color quality and brightness, too. The Droid DNA's screen is ever so slightly cooler and a little darker than the One X at maximum brightness, though these aren't differences you'll  notice unless you've got both devices sitting side by side. For general day-to-day use, both of these screens look stunningly good.

You'll be able to see for yourself when the HTC Droid DNA goes on sale tomorrow -- stay tuned for our full review. In the meantime, be sure to sound off in the comments, and stop by our Droid DNA forums for more great discussion.
