HTC announced a new phone in Japan last month called the “J Butterfly”. It's most interesting feature is easily the display: 5 inches with a resolution of 1920 x 1080 pixels. According to Engadget, two companies will be supplying HTC with said ultra sharp panel: Sharp and JDI.
JDI, which is short for Japan Display Incorporated, recently showed off two displays that are even better! The first is a 5 inch panel that also does 1920 x 1080, but it comes with two new technologies called WhiteMagic and Pixel Eyes. WhiteMagic is something that was first shown off in the Sony Xperia P back in February. Whereas a regular display has three subpixels (red, green, blue), a panel with WhiteMagic has an additional white subpixel. What does that give you? A brighter screen and better outdoor visibility. The second technology, Pixel Eyes, is just a fancy marketing phrase to describe a display that has the touch panel built-in instead of being a separate layer. The iPhone 5 has this.
Moving on up to 7 inches, JDI also showed off a display that has a resolution of 2560 x 1600. That's the same resolution as the recently announced Nexus 10. Because it's smaller, it's obviously sharper. How sharp? We're talking 431 pixels per inch. Like the new 5 inch panel mentioned earlier, this 7 inch panel also has Pixel Eyes and White Magic.
So when will these two displays find their way into retail products? Sadly there isn't a definitive answer. JDI made these prototypes to show customers with the hope that they'll place a large number of orders. If all goes to plan, mass production can begin next year, but we don't know if that means January, December, or somewhere in between.
Some of you are probably scratching your heads wondering why we even need such high resolution displays? There's no easy way to say this, so we'll be blunt: There's no such thing as “enough” when it comes to specs. Things can always be faster, brighter, sharper, thinner, and so on and so forth.
