The One X has a 4.7“ 1280x720 display that’s beautiful, dubbed the ”infinity screen.“ In fact, that’s really all you need to know about it - it’s absolutely wonderful, and honestly if you’re concerned with mobile displays just stop right there. At above 4.5” diagonal, 720p seems to be the new norm, and the combination of that 4.7" diagonal size and 720p on the HTC One X results in a PPI of 312. HTC shipped a device with an LCD display last year whose pixel density exceeded the iPhone 4/4S Retina Display for the first time in the HTC Rezound, which was 341 PPI.
Nevertheless the HTC One X still has subpixels small enough that I can’t visually distinguish them at all but from the most extreme distances. In addition, because it’s LCD you get an RGB stripe as opposed to PenTile RGBG like what currently ships on Samsung’s SAMOLED HD displays at 720p in the Galaxy Nexus.
I did some poking around, and my HTC One X (AT&T) review unit has a Sony display:
[DISP] mipi_video_sony_hd720p_init: assign initial setting for SONY_NT id 0x18103 Cut1, PANEL type = PANEL_ID_ELITE_SONY_NT
The panel goes extremely bright, at over 500 nits maximum, and has top of the chart contrast. As always I characterized the One X display using a combination of ColorHCFR and an i1D2 and Francois’ excellent Voodoo Screen Test Pattern generator application.
I’ve made both the color.chc file and measures available. The CIE diagram shows that HTC’s Infinity Display has very close to sRGB coverage, however color temperature is on the red side at just under 6000K. That’s really my only gripe, and curiously enough the One S with SAMOLED qHD displays are closer to 6500K than the LCD packing HTC One Xes.
Viewing angles look good on the HTC One X, there's no visible color shift at extreme angles. Outdoor viewing is also pretty good on the HTC One X, thanks in part to optical bonding between the display glass and LCD itself. One fewer air gap means fewer Fresnel reflections which quickly turn a display into a mess outdoors.

The Sprint version has a larger battery and some other hardware changes, I was wondering if Anand is planning on reviewing it so we can see how much the battery changes add and other stuff like Bloatware compares to this one.Impulses - Wednesday, May 2, 2012 - link
Slightly larger battery, kickstand, camera button, microSD slot, and a completely different casing made mostly out of aluminum (and some glossy plastic). Aesthetics aside, I don't see how it can be anything but an improvement, unless the CDMA stack gets bungled and it somehow wrecks battery life.Sprint has been pretty good about bloatware lately too, they were one of the first carriers to let you uninstall/hide some of their bloat even before ICS allowed it (most of my EVO 3D's built in apps could be removed/hidden, not all tho).
Their network is another story but since there's no VZW in Puerto Rico and AT&T treated me like crap I'll stick with Sprint for now, the EVO LTE helped their cause a bit too.

It wouldn't be the first time a Sprint CDMA version of a phone suffered worse battery life than the GSM version...Impulses - Tuesday, May 1, 2012 - link
Thanks so much for putting out this review this quickly, I know carriers often have a hand in what phones you get to review etc (this one in particular being pre release) but AT reviews continue to be a cut above anything else on the web.I seriously don't understand how you can be the only site out there that has a standardized method for battery life testing... Even beyond that tho, AT's reviews are simply the most informative, detailed, and less subjective phone reviews out there, bar none.

Oh and I'm looking forward to the One S and international variant reviews... I'm not even getting any of these phones but I still appreciate the work a lot. Any clue if you'll eventually get an EVO 4G LTE in for review? :pantef - Wednesday, May 2, 2012 - link
How did you remove the "AT&T" in the upper-left corner of the display in the status bar? Engadget had it displaying there in all of their pics. I would like to be able to remove that as well if I bought this since I don't need a reminder that I'm on AT&T's network.Impulses - Wednesday, May 2, 2012 - link
It's kinda curious AT&T is the only carrier doing that, and rather annoying since it's wasted notification space. Kinda redundant too considering they also silk screen it on the phone itself and it's also displayed within the notification pane and/or the lock screen (what everybody else does).1ceTr0n - Wednesday, May 2, 2012 - link
Simple, its marketing, like it or not. Likely will need to root phone and load different ROM to get rid of itantef - Wednesday, May 2, 2012 - link
I see it in some of the author's pics and not others. What's the deal?Impulses - Wednesday, May 2, 2012 - link
Apparently AT&T tag disappears when you actually have notifications, so at least they did that right.
