We've heard a lot of rumors swirling lately about HTC releasing a 5-inch 1080P phone, and it looks like the first proof of this device's existence has just shown up in Japan. The HTC One X's SLCD 2 screen still holds the title in most people's minds as the best smartphone screen on the market, but they seem to have outdone themselves with the SLCD 3 on the J Butterfly. At 5 inches and a full 1080x1920 resolution, this screen produces a staggeringly high 440 ppi (pixels per inch), much higher than any other display we've seen. If HTC's previous screens are any indication, this is going to be a huge step up in display technology going forward.
Moving along past the screen, the J Butterfly has a 1.5GHz quad-core Snapdragon S4 Pro processor, 2GB of RAM, LTE, NFC and an 8MP camera. For software, it is running Android 4.1 Jelly Bean with Sense 4+. It comes in a flashy red, more subtle black and white varieties, and will be released in Japan on KDDI in December. Hopefully we'll see this device's counterparts show up outside of Japan soon as well.
