Japan Display Squeezes 8K Resolution Into 17-inch LCD, Cracks 510 PPI At 120Hz

MojoKid writes: By any metric, 8K is an incredibly high resolution. In fact, given that most HD content is still published in 1080p, the same could be said about 4K. 4K packs in four times the pixels of 1080p, while 8K takes that and multiplies it by four once again; we're talking 33,177,600 pixels. We've become accustomed to our smartphones having super-high ppi (pixels-per-inch); 5.5-inch 1080p phones are 401 ppi, which is well past the point that humans are able to differentiate individual pixels. Understanding that highlights just how impressive Japan Display's (JDI) monitor is, as it clocks in at 510 ppi in a 17-inch panel. Other specs include a 2000:1 contrast ratio, a brightness of 500cd/m2, and a 176 degree viewing angle. While the fact that the company achieved 8K resolution in such a small form-factor is impressive in itself, also impressive is the fact that it has a refresh rate of 120Hz.

  1. Any monitor would crack at 510 PPI by fleabay · · Score: 5, Funny

    Any monitor would crack at 510 pounds per square inch regardless of the Hz.

    Before anyone goes around calling this pointless, the Japanese (as well as many other Asian countries) character system benefits from a higher resolution more than the writing systems used by most all Western countries. The symbols are far more dense, which makes the additional resolution more useful.

    Here's a good image that shows off that difference that additional resolution can achieve.

  3. What interface ? by x0ra · · Score: 4, Interesting

    4k already needs DisplayPort 1.2 to be able to push data at 60Hz. What interface can conveniently push 8k at 120Hz ??

      doing the quick math, 4k@60Hz require 14Gbps of bandwidth, so 8k@120Hz should at least be able to push 112Gbps... Not anytime soon.

      Apparently Embedded DisplayPort (eDP) 1.4a is claiming enough bandwidth and functionality to support 8k@60Hz, and in Feb this year they were expecting products to be available in 2016.

      "Embedded" means the spec is for laptop/tablet/phone and other all-in-one type devices (eg iMac).

    It's not so great. I've seen an image of the new display on the Internet and it has the same pixel density as my monitor.

    Remember to use gold plated connectors to get the best visual fidelity.
