HTC is putting all its hopes into the new M7 superphone it plans to unveil at MWC in February 2013. The M7 is supposed to be the engine that drives the company out of the rough patch it’s been going through for the last two years. But, to do so, the M7 must outshine the Galaxy S4, so the pressure is on HTC to deliver something truly special.

We’ve already seen a bevy of leaks concerning the HTC M7, from the rumored specs (quad-core Snapdragon S4 Pro, 2GB of RAM, 13MP camera) to appearance (metallic unibody, an alleged rendering) and even operating system (screenshots of HTC Sense 5). But there’s one issue that is a bit controversial – the display technology.

One rumor sais that HTC has booked the entire AMOLED manufacturing capacity of AU Optronics for the M7. AU Optronics (AUO) is a Taiwanese display maker that has been struggling for a while now to catch up with Samsung at manufacturing OLED-based displays. According to a Chinese website dedicated to OLED technology, AUO has finally achieved the 60 percent yield rate required to mass-produce the OLED panels that HTC requires for the M7.

Nevertheless, a recent report from Digitimes squarely contradicts the OLED rumor – AUO is not yet capable of delivering the goods, so HTC has opted for a 4.7-inch full HD LCD display manufactured by Sharp. Moreover, it’s said that the M7 will delight users with an incredible 468ppi pixel density, which is slightly more than the current record of 441ppi on the Droid DNA, Xperia Z, and a bunch of other devices.

So, which rumor should we believe? Personally, I think that HTC will stick with the tried and true LCD for the flagship M7, but the Taiwanese could use AMOLED for another device in their 2013 stable.

Last year at MWC, HTC unveiled three devices, the One X, One S, and One V, of which the One S featured an AMOLED screen. It’s likely that Peter Chou’s company is preparing a sequel to the One S, and not only the One X. We’ll see if my predictions are right in just a few weeks!
