Would You Use a Laptop with a Transparent Screen? (cnn.com) 92

At CNN's product review site, one electronics reporter wrote they were "dumbfounded", "surprised," and "shocked" by the transparent screen on Lenovo's ThinkBook Transparent Display prototype. "This Micro LED screen is no slouch, either; a Full HD panel with up to 1,000 nits of brightness..." Let's get the big issue out of the way early: Lenovo is merely boasting what it can do, not what it will do. That's what a "concept" product means, of course. That said, it's still the most exciting thing I've seen in laptops in quite some time...

Thinking of major use cases for such a laptop, I basically considered any time you're out in public and want a more complete world view. While websites with white backgrounds look more opaque than transparent, the black backgrounds of a Notepad document and animations of space and fish fit the experience much better, as I could see the plants that Lenovo had placed behind the screen. The more websites use dark modes, the better this will go, too. Admittedly, I can also imagine some will blanch at the fact that such a laptop completely removes your privacy as a user. From those shopping for loved ones in the same room to those working on important business documents, the ThinkBook Transparent Display laptop could use a non-transparent mode, just like the LG OLED T offers. That said, I'm sure teachers would love to see what their kids are working on in the classroom.

The Verge calls it "an exceptionally cool-looking device that's capable of some fun novelties." The key draw is its bezel-less 17.3-inch MicroLED display, which offers up to 55 percent transparency when its pixels are set to black and turned off. But as its pixels light up, the display becomes less and less see-through, until eventually, you're looking at a completely opaque white surface with a peak brightness of 1,000 nits... How often, of course, do you actually want to see the empty desk behind your laptop? Would it be beneficial to be able to see your colleague sitting across from you, or would it be distracting? One of Lenovo's big ideas is that the form factor could be useful for digital artists, helping them to see the world behind the laptop's screen while sketching it on the lower half of the laptop where the keyboard is (more on this later).... 720p still feels like a very work-in-progress spec on a 17.3-inch laptop like this, but at least text shown on the screen during my demo was perfectly readable... Lenovo's transparent laptop concept feels like a collection of cool technologies in search of a killer app.
And yet Lenovo's executive director of ThinkPad portfolio and product Tom Butler tells the Verge he has "very high confidence" this will be in a real laptop within the next five years. (The Verge add that he "hopes that revealing this proof of concept will start a public conversation about what it could be useful for, setting a target for Lenovo to work toward.")

      Well, 30 years ago they used similar transparent screens to put a computer display onto an over-head projector.
      • by jevring ( 618916 )
        That's true. I remember those. I imagine that's pretty niche, though. I don't think a lot of teachers will want this just so that they can fold their screen over on top of an overhead projector.
    • "drag and drop selecting just did not work with the touchpad"
      That is not a flaw of the demonstrator. That is a general problem with the whole company. They seem to be incapable of providing reliably working drivers for their devices...
      Try to use their laptop together with their dockingstation on a Windows basis. It's an horrible experience.

    • This is how the Apple Vision Pro works.

      You can set the background to transparent and see what is happening around you while your apps are suspended in front of you.

      It makes sense in goggles. I don't see the point in a laptop.

      • by narcc ( 412956 )

        What gave you that idea? Apple's thing, like just about every other VR headset, uses outward facing cameras to simulate transparency. This display is transparent.

        While there are endless applications for that kind of display, this is just a tech demo. Lenovo isn't trying to sell you a goofy laptop.

      • Agree. The tech is useful for AR goggle, but not for any traditional form factor computers.
        • Actually, not supremely useful in AR. The rendering would be impossibly close to eyes if directly emitting. To correct for that, you need lenses. The lenses would destroy the passthrough.

          Basically, the bare glass ar approach requires a projection system to have the light be at the right focal length. Also the approach is fundamentally limited in field of view and opacity. So camera and applying to display is the popular approach now, well so far as any ar is "popular"

            The XReal Air 2 Pro glasses that I'm wearing right now use birdbath optics to project the image. As far as opacity goes, they're about as dim as my regular sunglasses, but I can press a button to dim the front lens more. I can adjust the image however I like, from barely visible to completely opaque.

            • by Junta ( 36770 )

              But can it make a fully opaque rendering of an AR object on top of a completely undimmed real world? I've never heard it pulled off, and it seems like you would have to have some form of dynamic blocking to even have a hope, since the reflection can only ever add to the passed through light, never subtract. So the AR content has to overwhelm the real world content.

      > I'm not sure what the value is outside of the coolness factor.

      As a monitor, not much but as a heads up display I can see several interesting uses, such as "smart windows" which can be both windows and displays at the same time. If the light output can be made one directional, then you can have privacy too as you look out your house through the transparent display window but others looking in see nothing but you.

      That would be a "home of tomorrow" kind of thing and unlikely to be installed in anything but designer houses etc.

      But in a museum it could be used to provide transparent displays that can be seen from both sides. It would also work in art and photography exhibisions perhaps. When thought of as a window, a structural element in a buiding that also can display stuff but still allow window like fuctionality then I can see many uses.

      I also like the idea that it could be used in something like a ATC tower, the windows in the tower could highlight and plot details of aircraft within a certain range aurgmenting the standard radar system.

      Then of course it would revolutionise augmented reality, no longer will you have to look at a camera image but can look at the real world with graphics overlaid on top.

      • But in a museum it could be used to provide transparent displays that can be seen from both sides

        The only issue being the reverse view from the back. People would have a hard time reading text for example, or perhaps making sense of a physical layout.

        We actually have that now in more than one affordable consumer product. The XReal Air 2, for example. Though if you're in the market for one of these lightweight AR headsets with real transparency, it might be worth waiting a little while for the Immersed Visor. It looks to be a real game changer.

        Indeed. A car windshield using this kind of technology for a google maps style overlay directly on the road instead of having to take your eyes off it could be incredibly helpful. Could also provide much better warning about surprise turn-only lanes coming out of nowhere in areas you aren't familiar with.

        That said, I'm also imagining a future where marketers try to hijack such a display to force ads on you, or hackers setting off a light-show to try and cause accidents. The potential for abuse is terrify

        • Indeed. A car windshield using this kind of technology for a google maps style overlay directly on the road instead of having to take your eyes off it could be incredibly helpful.

          This is why I always mount my phone on my dashboard so that when I look at the phone to check my route, the change is much quicker than if I have to look down and away from the road. I can still see the road ahead and can change from watching the phone back to the road almost instantly.
        • I think the bigger issue with the âoewindshield is a displayâ concept is that the focal point of the driverâ(TM)s vision should be somewhere around 10m in front of the car or greater.

          This is the main reason why HUDs in cars are not common and/or have optical limitations. Integrating the optics required to focus the image further away than reality requires a long optical path, or at least hardware sophisticated enough to simulate it. Generally speaking, these approaches have eye relief and fie

    • Could we produce "Minority Report" type screens with this technology?
    • If it works the way I think it does, it could allow for true "optical AR", in a way that neither HoloLens (everything is semi-transparent) or Vision Pro (camera-based, not optical) can do right now. So, yeah, don't put this on a laptop, put it in an HMD.
  • ...but I would not use it. You can get a similar effect with semi-transparent windows on most GUIs, but I find it distracting. This takes it to a whole new level.

    Pretty cool though, so I'm sure there will be a market for it.

      I remember when transparent windows were new and all the rage. It looked so cool. Of course I had to get myself a good desktop background so there was something for the windows to transparent to and I admired the slick look of my xterms gently blending into whatever was behind them. I have a vague memory of hacking together some keys to bump up/down the transparency of whatever was in focus.

      And then...

      well transparent windows may have been new, but in principle the technology didn't stop us from having background pictures in terminals before that. Turns out there's a reason we didn't because making the text less clear sucks, and transparency was just a fancy way of doing that.

      I don't think I've actually used a main transparent window since about 2 weeks after I first got them in the early noughties.

    This is not a laptop to use in public, or even when other people could enter tthe room. Even if there's nothing to hide, it's still private what I do.
    Any view of what's behind the screen, moving or not, would be an extra distraction factor from what I'm watching on the screen.
    And who knows how clear the display is during the day, seeing how I dislike bright backgrounds and have set everything possible to dark colours all the time.

    It doesn't make sense to me even in science fiction, but that's the only place I see any real use for this.

      Absolutely no usage cases for where you don't want to share the contents of the screen with others, although a simple snap-on cover would solve that and give you at least the option of sharing the screen (and allow for an after-market in replacement/custom cover designs). As long as you don't include text on what you're sharing, because it's going to be mirror writing from one side or the other depending on how you draw the screen, you're good.

      Here's a possible usage case though. Assuming a traditional clamshell design with a slim base and keyboard with illuminated key lettering, fold the screen flat against the keyboard, turn off the keyboard LEDs, and you've got a conventional, if slightly bulky, tablet without the need for a complicated and fragile hinge that lets you turn the screen through 180deg like current hybrids. If the screen is touch sensitive and it includes a stylus, I can see that might appeal to at least some graphic artists or people looking to do some light work or reading while they're commuting, yet still have a traditional laptop available once they arrive.
      • Great idea. You could use old school LCD to put a black layer on the back side so that it could be opaqued, or a newer electrochromic technology if that would work better.

    • This is not a laptop to use in public, or even when other people could enter the room.

      At least not without a modesty panel.

    • This. Sadly, manufacturers will move ahead regardless of security, and rest assured the ignorant consumer in a trigger-happy litigation system will want to sue the first time someone walks by and “steals” their credentials. It’s only slightly worse than the sticky note on the bottom of the keyboard.

      • by nasch ( 598556 )

        An attacker would not normally be able to steal credentials by looking at the screen. Masked passwords have been pretty standard for... 20 years?

    It's obviously for tracers, you know, the "artists" who add depth and shading to give the image mere definition so that the drawings really take shape.

    I'm assuming the transparent screen can be laid flat over another screen or page to enable tracing. You know, because they're tracers.
  • No, because others can see from the other side what you are typing (passwords) or viewing.
    I'd rather have a non-transparent screen that replicates what would be seen if transparent by way of a camera.
    Bonus points if I can choose an arbitrary web cam (e.g. baby monitor or remote meeting participant) as the background video instead.

        • Until you make it plain text to see why you cant log in today...

    Anyone remember the trend of making a mock transparent screen by taking a photo of whatever sits behind your monitor, setting it as your desktop wallpaper, then taking a photo of your PC from the same angle? I think it was mid-2000s. It's always been a cool concept from an aesthetic standpoint, although I remain to be convinced that it has much value otherwise.

  • This would be usable if there was a grayscale LCD behind it to control the opacity. Its opacity would correspond to the alpha channel of RGBA framebuffers, but there is probably no GPU out there that is capable of driving a separate LCD with every fourth byte.

    As a monitor I dont think there will be much call as most monitors used by most people in most settings add some security to the fact that people cant see what you are doing.

    But:

    - Augmented reality glasses will now work as intended. That is to say you wont be looking at a camera image, you can have proper transparent glass that "paints" the view with the graphics you expect to see.
    - Museums and exhibishion halls/events. A display that can be seen from multiple directions but also be transparent to not obscure other tings and people.
    - Windows with smart features. Like with AR use only its a proper window with in-built transparent display capabilities. If the light can be made to be seen only by the occupants then you can have privacy as well as a big window to look out from. This might only be used by concept houses and the rich but it could also be used in schools.
    - Keeping with the smart window idea, I thought it could be used in an ATC tower to augment the current radar displays, where the aircraft can be highlighted on the window itself!

    • - Augmented reality glasses will now work as intended

      Except for parallax. If you move your head at all, the overlay no longer lines up with the background. Could maybe be solved with eye-tracking software in the camera. (Is there a camera in the display? Or is it one of those stupid up-the-nose cams on the keyboard?)

      Why not stack a bunch of these displays into a cube and have an actual 3d display? I imagine it would be extremely expensive at this point to have a display with suitable thickness, but you would be able to control actual "voxels" if data.

      They would have to work on the transparency. If each layer reduced light by 50%, that would get opaque pretty quickly. But if they could get that down close to 0%, it would be a very neat display!

  • so that you can see the actor's face. otherwise, either the camera would have to be awkwardly positioned behind the screen, with the screen blocking the view, or the audience would be staring at the back of the actor's head to see what's actually on the screen.

    oh, and it makes everything looks futuristic, somehow.

    I don't think they have much purpose in the real world, though.

    I'd far rather that than literally ANY other gimmick like folding screens, see-through screens, etc.

    If you can't make it cheaper or better (including more resilient, brighter, etc.)... then don't worry about the screen. Find something else to do instead.

    Gimmicks don't sell me on ANYTHING at all. I'd far rather have a basic, non-gimmicky thing that was slightly better and/or cheaper.

  • Anyone remember that on Linux (maybe other OSes too) you can make your xterm terminal window transparent to any amount you want. It's cool and distracting. I always set transparency to 0% to block it. Likewise, transparent displays probably have their use, but it's very limited in application. I would turn the transparency off.

  • As others have pointed out, we tend to use laptops in public environments where there are both other people that we might not care to have looking on, as well as possible moving objects/people/birds in the background. Also, the screen isn't so big that it's really obscuring much of a view.

    But as a monitor for a desktop? Sure. A large, transparent monitor means I wouldn't always need to face the wall to type or have a big "wall" blocking my view of other parts of my office, or people I might be meeting with

  • I can see using this, if you tape cardboard over the back of it.

    Take for example the hand terminals from The Expanse [pinimg.com], which look very similar to what Lenovo is doing here. Everything behind the screen would be nothing more that clutter in your field of view. You'd also need to be very careful, lest what's behind the screen wash out what you're trying to look at on the screen, (white text on a transparent screen with a white wall behind it, for example.)
