HTC has announced the J Butterfly phone, which will be aimed, at least initially, at the Japanese market.

Without doubt, the biggest selling point of the new device will be its highly developed 1,920 x 1,080 display, which will measure in at 5in and pack an incredible 440 PPI. To put this into context, the Samsung Galaxy Note 2 and iPhone 5 have pixel densities of 267 and 326, respectively. HTC is placing much emphasis on the phone's suitability for watching 1080p videos.

It won't just be a one trick pony, though. The device will also be equipped with a Qualcomm quad-core Snapdragon APQ8064 processor, clocked at 1.5GHz, 16GB of storage, 2GB of RAM, and an 8-megapixel rear camera capable of 1080p video. It will run on Android 4.1 Jelly Bean.

Additionally, it will ship with Beats Audio pre-installed, as well as NFC, LTE, Bluetooth 4.0 and 802.11 a/b/g/n Wi-Fi.

The J Butterfly will hit Japan's stores in December, but it is still unknown as to whether it will launch elsewhere. If it doesn't go global, there's sure to be many a non-Japanese consumer left disappointed, for the screen's quality alone makes the device remarkable.
