Sharp wants to get in on the 4K phone display action early.

The Japanese display maker is looking to elevate the smartphone screen to unprecedented levels with a new 5.5-inch touch screen that is capable of showing images in 4K. As Techblog.gr reports, Sharp's new IGZO display has a resolution of 840-by-2,160 pixels, or 806 pixels per inch (ppi).

For those keeping track, that's about twice the resolution of the iPhone 6 Plus and Galaxy Note 3. But that huge bump in resolution probably won't make too much of a difference for most people, according to Wired. You'd need super-excellent eyesight — or a magnifying glass — to even notice subtle differences in very detailed graphics and tiny text.

"In many/most cases the additional sharpness and resolution are lost for most people, most applications, and most viewing conditions," Raymond Soneira, president of DisplayMate Technologies, told Wired. On a more positive note, it would, however, make it easier to rescale Full HD content, which is becoming increasingly standard.

Another downside — it would probably cut down on battery life big time, considering all the power needed to keep that massive amount of pixels lit up.

As for whether Sharp's new 4K smartphone screen will make its way to handsets any time soon, we'll just have to wait and see. The company did not immediately respond to a request for comment.

Late last year, Sharp launched the Aquos budget smartphone (pictured), which sports a 5-inch, 720p IPS LCD panel at 293ppi for only $149. Its edge-to-edge screen impressed, but call quality left something to be desired.

Meanwhile on the 4K front, Vizio just yesterday launched its second Ultra HD TV lineup, offering a range of screen sizes from 43 to 80 inches, with prices starting at just $600 all the way up to $4,000. The new TVs display more than 8.3 million pixels in every image, offering four times the resolution of 1080p Full HD for "breathtaking detail and clarity," Vizio said.

My Experience

I'm PCMag's managing editor for consumer electronics, overseeing an experienced team of analysts covering smart home, home entertainment, wearables, fitness and health tech, and various other product categories. I have been with PCMag for more than 10 years, and in that time have written more than 6,000 articles and reviews for the site. I previously served as an analyst focused on smart home and wearable devices, and before that I was a reporter covering consumer tech news. I'm also a yoga instructor, and have been actively teaching group and private classes for nearly a decade. 

Prior to joining PCMag, I was a reporter for SC Magazine, focusing on hackers and computer security. I earned a BS in journalism from West Virginia University, and started my career writing for newspapers in New Jersey, Pennsylvania, and West Virginia.

The Technology I Use

My little Florida beach bungalow is brimming with smart home tech. I have a smart speaker or display in every room, allowing me to control other connected devices by voice. The Nest Hub on my bedside table lets me set wake-up alarms, control my smart light bulbs, and set the temperature on my smart thermostat. I use the Amazon Echo Show 8 on my kitchen counter to browse recipes, reorder protein powder, check the weather, and watch the news while I do dishes. 

Because I suffer from allergies, air purifiers are essential. My favorite model is the Dyson Purifier Cool TP07, which doubles as a fan and continuously sends indoor pollution data to its companion mobile app. 

My pitbull Bradley sheds, so a good robot vacuum is a must. I currently use a premium Ecovacs Deebot that can both vacuum and mop, empty its own dustbin, and wash its own mop cloth. 

For fitness, I like to mix up my routine with cycling, indoor rowing, running, and strength training in addition to yoga. I take classes on the Tonal 2 smart strength training machine, I row indoors on an Aviron machine, and track my beach runs with an Apple Watch while listening to music on my Apple AirPods Pro. On the weekends, I love riding e-bikes like the rugged, beach-friendly Aventon Aventure for fun and fitness.

My job involves a lot of virtual meetings, so a quality webcam, microphone, and ring light are important. I use the Jabra PanaCast 20 webcam, the Elgato Wave: 3 microphone, and a Yesker tripod ring light. 

As for my preferred phone platform, I'm an iPhone person, but I've also extensively used Android for product testing.
