Apple may claim that the iPhone has a “Retina” display because it’s hard for the human eye to distinguish individual pixels on a phone display when you can pack 326 pixels per inch. But Japan Display laughs at the iPhone’s 4 inch, 1136 x 640 pixel screen.
The Japanese display maker is showing off a new 5.4 inch, 2560 x 1440 pixel display with 543 pixels per inch.
While Chinese phone maker Vivo is already working on a smartphone with a 2560 x 1440 pixel screen, the Vivo Xplay3S has a 6 inch display — since Japan Display’s screen is smaller, the pixels are packed even tighter.
It’s questionably whether there’s any good reason for a screen that size to be that sharp — it’d probably be tough for most people to tell the difference between a 1080p smartphone screen and a 1440p display. But it wasn’t that long ago that 720p screens on smartphones seemed pretty amazing.
Japan Display says its new display measures 1.12mm thick, offers 160 degree or better viewing angles, and offers low power consumption.
The company also has a 6.2 inch screen with the same resolution, but it only manages to pack in 473 pixels per inch.
Japan Display seems to be going all out on high-resolution displays. The company also introduced a 12 inch, 3840 x 2160 pixel display for tablets and notebooks recently.
