'We're Working On Rollable Phones,' Says LG CTO (tomsguide.com) 70

Posted by BeauHD from the ready-or-not-here-they-come dept.
In a wide-ranging interview with Mark Spoonauer from Tom's Guide, CTO and president of LG Electronics, IP Park, said his company is working on both rollable and foldable smartphones, regardless of whether there's demand for them or not. Here's an excerpt from the report: Are you looking into rollable and foldable phones as well? We are exploring many different form factors for phones, including foldable and rollable. Because display technology has grown so much that it can make it into very flexible form factors. And with 5G, if the market requires much bigger screens, we'll need to fold it or roll it. So we'll explore.

A lot of people are saying the whole smartphone market has stagnated and there are even some who argue that LG should exit the business altogether. What's your reaction to that? The smartphone business is very tough because of the competition. Also because of the penetration. Everyone has a phone now, right? Everybody has a big screen, and everybody has many features that others have. I think this year could be the year of the upgrade in the smartphone industry because of 5G. 5G is going to be available this year, and people will come out with 5G phones. And 5G is different from LTE, not only because of bandwidth, but also latency. You may want to have even bigger screens on 5G phones because of the more content you can get. That could trigger different killer applications that you run on phones.

      None. Foldable and rollable phones are just the latest non-feature to get the market hyped on because the mobile space has run out of new actual features to add. Smartphones have been fundamentally identical for years, so the manufacturers are conjuring distinctiveness from nothing.

    Rather than concentrate on making displays that are bigger/collapsible, what is the state of the art for getting displays that cause icons/information to appear in the air around the phone?

    Is that complete pie in the sky or is there some way to get molecules of oxygen/nitrogen in the air to fluoresce and provide information outside the area of the phone and its physical display?

    • There are some laser "hologram" technologies able to draw some simple, small linear figures in the air, but they're nowhere "mobile" sized, and it's possible that they'll never be, because physics.

      • I think this could never be eye-safe, not even skin-safe.
        To render something in the air I guess the laser intensity must be so high that the air turns into plasma. If you put your finger where the spot is it will definitely get burned. And the light passing through the spot will damage the eye. I think that's impossible to avoid, unless maybe if the laser is focussed very strongly, meaning that it only works very close to the focussing lens.
      • Oh, nevermind, they found a less crazy way :) They move a particle with an optical trap. This works with pretty low intensities, though the motion speed and acceleration of the particle are limited

        • Read both articles, they're different technologies. The first one does use plasma only, without a moving particle. They tested it on leather, and they found that femtosecond laser bursts didn't burn it and was safe. Of course I wouldn't try projecting it on eyes, but that's fairly common advice wherever lasers are involved.

          • Ok thanks, that looks interesting. Well, probably the laser is ablating the skin and leather pretty slowly. i think it is impossible that it could be below the damage threshold of skin or leather, unless it is reflected near 100%. This also seems impossible though, since these intensities lead to multi photon absorption.
            My point is, it could be ok in a controlled environment, but such "dangerous" things won't get permission for consumer devices nowadays. Laser safety rules are pretty strict. The optical tr

      It's probably pie in the sky I'm afraid.

      The problem is that there is no way to control the air molecules. You can't bounce light off them, you can't heat them in any kind of controlled manner good enough to make an image.

      A more practical option is contact lenses with displays in them and some kind of wireless link to the phone. Can you imagine the security nightmare it would be though.

    • Why? Every time I see something like this (or transparent monitors, see "Minority Report") I think with all the concerns about privacy why would anyone ever want a device (phone or monitor) that allows everyone around them to see what they're doing? Besides the fact viewing transparent objects against bright backgrounds would be a usability nightmare.

    I think this year could be the year of the upgrade in the smartphone industry because of 5G. 5G is going to be available this year, and people will come out with 5G phones.

    I know this is BS speak (marketing) but still, almost everything is wrong in that statement.
    First of all, most people won't care about 5G and won't upgrade until forced to (new phones will be 5G, and old phones will break or become too slow at some point). Just like when going from 3G to 4G, except that it is going to be even worse since the added bandwith isn't as useful.
    5G definately won't require or even benefit from bigger screens. Altough he's right that phone screens keep getting bigger every year, but this has nothing to do with 5G. And finally, there won't be any killer 5G application, especially not this year.
    The first 5G phones are probably going to suck (expensive, poor battery life, non-existing networks) anyways.

      I tend to agree with all that: 5G could turn out like 4k televisions: the tech is there, prices are dropping and people are buying it... but the vast majority of people still do not have a compelling reason to select devices that support the tech, other than bragging rights.

      That idea is supported by the statement that the smartphone market has stagnated. People do not upgrade as often as they used to. And I suspect rollable phones and 5G are not going to change that. But it’s silly to think that’s a reason to exit the smartphone market. It is however a reason to rethink your value proposition: instead of thinking about what features you can keep adding that will make customers upgrade their phones every 2-3 years, think about what you can do to make consumers select your phone to use for the next 5-7 years.

      • think about what you can do to make consumers select your phone to use for the next 5-7 years.

        Headphone Jack
        Thicker case to hold a larger, user replaceable battery
        Fi compatibility
        microSD card slot
        Two USB-C ports. One for charging, one for other stuff.

          All out of keeping 1/10th of 1 percent of the populous happy. Good luck.

    • Not many people are going to want to stream 4K over a cell phone plan to a display of any size unless the data plan prices change dramatically. I'm not sure 5g is even going to be that great, it's almost entirely line of sight only. Even with beam forming it uses a ton of power at high bandwidth which only makes current battery limitations worse.
