Sharp's recently issued a cell phone with a 5.5-inch 4K display, which makes us think smartphones will have more new high lethality. Nevertheless, such high pixel products do in fact have it: make more realistic virtual reality products.
No doubt, sharp's small IGZO ultra high resolution display will use Smartphones, such as strong flat-screen mobile phones iPhone 6 Plus. (It was reported that sharp is one of Apple's suppliers of screen) and market calls for 4K display is clearly very high: the more, the quality is getting better and better!
But the reality is not so. Sharp's latest product 3850x2160 resolution, which has 806 pixels per inch (PPI), almost twice the iPhone 6 in pixel Plus and Galaxy Note 3 on the screen, and on both phones to distinguish with the naked eye pixels is less likely.
In regular distances, you can only recognize half of the 5.5-inch 4K display pixels, in most cases, the majority of people, most applications, most cannot be identified with environment high definition and resolution.
In other words, we don't need such high resolution.
This is not to say that 4K displays can retire the rivers and lakes. It also has some incidental advantages, one of which is 4K can easily become full HD content. However, this advantage has failed to convince us with a 4K screen, especially when you take into account the electricity consumption. In addition to the battery-benefits, and what are the other benefits?
Ahem, or calm down a little. Anyway, the main target beneficiaries of sharp 4K screen is not a smart phone.
The virtual world
If you haven't played the virtual reality devices, such as the Oculus Rift or HTV Vive, you do not worry, this does not mean you are out. Have been developed for a number of years, and prospects are good, but still not on the current market of high-end head-mounted virtual reality display. Secondly, you need to know, no matter how exciting you read first-hand accounts of publicity materials, these devices are much improved.
5.5-inch 4K 806PPI display can accelerate this process.
Brian Blau is the consumer technology analyst at Gartner research. Virtual reality is one of his subjects. He said virtual reality head-mounted devices will benefit from the application of super high resolution screen, this benefit will be very obvious. Paul Frank iPad Air 2 Case
"If the screen resolution is not high enough, it is easy to see the individual pixels," Blau said. Most virtual reality head-mounted device using optical lens elements on the screen larger, shortcomings are magnified, and easier for people to see the pixels. Virtual content created by two separate images, this makes the final image is not clear.
Therefore, high resolution screen means that people no longer see the individual pixels. Duang sound, virtual worlds are very clear. People couldn't believe it.
Although from a Smartphone-based headset such as the Google Cardboard, to fully integrated devices such as HTC and Oculus Rift Vive, 4K screen, but a separate headset should be the biggest beneficiary. They are often connected to the computer, without worrying about battery life issues, can also make use of powerful processing power of computers. New sharp screen before they reach the mass production next year, the Smartphone industry will see tremendous development, may be able to maintain quality 4K virtual reality experience for a long time.
So we don't have to worry about 5.5-inch Smartphone display pixels high cannot recognise. If you look at virtual reality, you have grounds for excitement. If virtual reality is to be welcomed, it must become more realistic. Sharp 4K screen and other inventions which will come later, and will promote the development of virtual reality head-mounted devices in the future. Paul Frank iPad Air 2 Case

"It will give 6 iPad charging at full speed, I still 5 iPad." 2A charging equipment will be more and more, if you already have more than one such device at home, while the pursuit of efficiency and convenience, this 6 monster really worth considering. For me, now there are 4 full speed USB is very happy.
