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.

      Nice strawman, but comparing 600dpi and 1200dpi printing to solid gold toilets is excessive... like solid gold toilet excessive. And yes there's a market for that, but let's consider that niche and leave it at that.

      Of course your flawed point above doesn't mean that the essence of your previous post is invalid, as evidenced by how Intel introduced the Pentium 4 at the time - competing on just the PR metric of the CPU frequency. But in the big scheme of things, the market rectifies it... as with the case of the Pentium 4 :-) Not only that, but also, we're still on the same frequency where the P4 peaked, and it didn't stop sales; progress shifted to parallelism and efficiency.

      With displays, sure, it would be good to increase the color spectrum, lower the power consumption, make it thinner or less fragile, make it transflexive, or holographic, etc. Some of these (e.g. color spectrum, response time, thin borders) do show various levels of improvement over time. But, as with semiconductors, one of the low hanging fruits is miniaturization, i.e. trying to do essentially the same thing on a finer scale. If I can increase product sales by quadrupling the resolution less expensively than I can by increasing the color spectrum by 10% then I'll do the former.

      This doesn't mean that resolution is the only thing. But it's on the uptick now since the initial iPhone, through the retina iPhone, to the 400-600dpi Androids. I don't choose a 600dpi phone over a 400dpi phone if its BOM is a lot higher (i.e. the street price is slightly higher). But some stuff scales more with physical size than resolution, once that resolution has become mainstream. The LCD is somewhere in the range of $20 per phone so don't worry much.

      What's good however is that we're getting past the desktop resolution winter. Back in the last millennium it was easy to get a CRT with a resolution of 1600x1200 and more was possible. Then the age of desktop LCDs came and it made almost everyone stuck at 1920 x 1200 or worse, for almost twenty years. My 13" Thinkpad 600 from 1997 had a resolution of 1280 x 1024 and then for almost 20 years, laptops with 1366x768 and some FHD ruled. So it's high time that desktop and laptop users benefit from what the mobile users benefit from: pixels that are hard or impossible to make out. The ultimate threshold is not what's invisible individually. It's useful to go a couple of times past what the human eye can't see even in proximity, because that'll eliminate the need for aliasing, and it'll allow smooth upscaling of whatever content (try to upscale a 800x600 desktop to 1024x768 lots of distortions unlike upscaling to 1600x1200 - round multiple - or some random large 6439x4389 - indecipherable pixels).

      It's not true that there's no utility to progress even if you don't need that resolution today. For example, VR requires incredibly high resolutions. Technology always works by realising gains via exploiting low hanging fruit, economies of scale, mass market etc. - only then can new technologies proliferate, as they don't need to pay for the entire tech tree from the discrete transistor or LED up to whatever we have now. VR is an expected future application, and there may be future unexpected applications, the same way the Web wasn't really anticipated by Babbage.

      You personally may be content with a phone with state of the art internals but a low res screen. You can buy an iPhone with a 326dpi resolution and the fastest mobile CPU/GPU on Earth. Or you can buy a non-flagship Android. But if you find that you can't buy the phone of your high general expectations and low DPI, then maybe you're the niche market. Maybe they'll cater for such niche markets the same way you can buy diamond studded cars. Features need to be in some balance and even in this niche, you can probably buy a diamond studded Ferrari more easily than a diamond studded Yugo.
