The race to recognition as the world's first 4K smartphone is on.

Citing information from techblog.gr, BGR reported that Sharp has already announced a screen worth 3840 x 2160 pixels, fitting 5.5-inch phablets. Such display, housing a density of 806 pixels per inch, is expected to appear in next year's handsets.

According to BGR, these 4K IGZO displays are set to face Samsung's 4K AMOLED panels. The rumored Galaxy Note 5 is purported to pack the latter, being first for the company.

Shorthand for indium gallium zinc oxide, IGZO is known to be a high-performance technology capable of yielding crystal clear displays. Sharp describes, "IGZO is a revolutionary, transparent compound semiconductor that Sharp is the first to successfully mass-produce and bring to market."

Interestingly, IGZO is recognized for efficient energy use, saving battery life for longer device usage.

The need for 4K (Ultra HD) displays among smartphones has been questioned several times already. In November, Android Authority took note of Qualcomm's argument, which suggested that 4K brings benefits other than visual acuity.

Qualcomm wrote, "At around the distance of 10 inches, people with average vision can discern an image with ~344 PPI, and people with perfect vision can discern an image with higher resolution up to ~573 PPI."

"However, visual acuity alone can't explain the complexity of the human vision system," the company pointed.

As told by Gizmodo, Apple decided in 2011 that the human eye can only hold a resolution of about 300 ppi when using a phone. But because of the recent hype brought by virtual reality systems, more questions are eventually raised.

Yet before anything else, the outlet is convinced that Sharp may need to address mass production, including how such resolution would affect battery life. As some smartphone users would feel, stunning resolutions are not just pain in strained eyes, but in power as well.

While some could be looking forward to the release of such smartphones, ZDNet reminded that the first of these displays are "likely" going to China.

Meanwhile, rumors aimed at the Samsung Galaxy Note 5 peg the device to own a processor called the high-density EPOP memory. It is said to combine 3 GB LPDDR3 DRAM, 32 GB eMMC (embedded multi-media card) and a controller.

Ultimately, the chip will enable "speedier multitasking and slimmer handset designs," Know Your Mobile wrote.

Expected to arrive between August and October 2015, the Galaxy Note 5 is allegedly packing a 5.9-inch screen, 4 GB of RAM, 21 MP main camera and 4,000 mAh battery. Price is speculated at around $900.

Are you looking forward to see 4K display in smartphones? Is such upgrade necessary? With consideration to size, what resolution is enough for handsets?
