Samsung Develops a Transparent OLED Laptop Screen 148

Dyne09 writes "The Design blog has posted an entry on Samsung's new laptop with a transparent OLED screen. The photos show a dark-tinted and dimly-lit screen that is fully see-through. While the utility of a see-through laptop probably isn't that high for the average user, several medical and industrial industries could greatly augment design work or frame 3-D models over real life in real-time."

      IBM ThinkPad 755CV had a transparent LCD display (VGA resolution) around 1995. It could be detached from the laptop, and placed on an overhead projector, for making PowerlessPointless-style presentations. This was in the days before projectors were common.

    I had two ideas come to mind on ways to use this technology (laptop screens don't really seem like a killer feature).

    - Glasses. It would be great to get a screen on the lenses of my sunglasses, most of the time they'd be clear like normal, but info could pop up throughout the day as needed. Or I could sit back and watch a video, and just turn it off if I needed to see something.

    - 3D Displays. If one would take many layers of this together, it would be possible to create a 3D display a couple inches deep that would be able to be viewed without any need for glasses. It would be quite limited to the amount of depth available, but even a small amount could be revolutionary.

      How about using this on a hybrid laptop/tablet? Instead of having an mechanical swivel for the screen that can break, just have a transparent screen like this. Open it up and it's a laptop. Shut the laptop and the screen mirrors so it's a tablet now. This is assuming you could get the outside (or back of) the screen to have touch capabilities.

I'm surprised Samsung didn't learn anything from the public's reaction to transparent GUI windows. They're kind of cool as a novelty for about 5 minutes, but nobody really wants to use them.

    there certainly is some geek coolness in having a transparent display on a laptop, although I question the usefulness of it; particularly when one is playing back pr0n on said laptop.

  • Like meseums, trade shows etc etc, it would really pull people arround them despite only being able to read properly from the one side. Countless movies and TV shows have transparent screens in high tech work places, it's all good as long as it's not too bad on the eyes if it's to be worked with a lot, or if any private data ever needs to be shown it's useless.

  • I can't see much use for an overlay unless there is a fixed viewpoint or the display is only used for information that does not need to be synced with what is behind it. Move your head a few centimeters and it'd throw it all askew.

    The other problem I see with this, as someone mentioned glasses is the focal distance. The heads up displays and wearable computers, etc, that I've seen used mirrors and optics to achieve a further distance than trying to focus on the lens of your glasses.

      I don't that would work very well. Current HUDs [wikipedia.org] use an optical system to allow the generate imagery to be focused at infinity, that way the pilot/driver doesn't have to refocus between the outside world and the generated image.

      No, translucency prevents seeing details through the medium, such as the glass you'd use in a bathroom window which allows light to pass through but scatters the photons preventing seeing detail. Transparency is a sliding scale, which can allow various levels of light through or even only certain wavelengths (colors) from 100% clear transparent to nearly opaque.

    • It if were transparent then it would be clear

      Transparent means the objects behind the glass are in focus, which they are in this case.

      The amount of light the glass lets through is a separate consideration from the transparency/translucency distinction.

    • It's translucent. It if were transparent then it would be clear, instead it's like a dark tinted piece of glass which isn't that easy to see through if you ask me.

      It was supposed to be transparent, but if you look at the demo you'll see they're running Windows - Internet Explorer doesn't correctly handle opacity.

    Instead of having LED below the e-ink, put it on top of the e-ink. With no current applied to either, you see the e-ink. When you need to use the faster more colorful tech, make the e-ink whitish and turn on the OLED.

      It is too dim to have a purely reflective technology at the back. The OLED is only 40% transparent, any light bouncing off the e-ink has to pass through the OLED twice (once from the light source to the e-ink, and once form the e-ink to the viewer). At the end you only have 16% of the light being reflected, minus whatever the e-ink absorbs. The reflections of the top of the OLED will be brighter than the displayed information from the e-ink.

      It's only 40% transparent - the effect would be to render the e-ink unreadable (or near unreadable). While I think it's fantastically cool, I can't think of a single good use for the technology. I can think of a couple of bad ones:

      Make it a touch screen, and put it on the door of your microwave oven - now you don't need the panel to the side... still need to put that volume somewhere (that's where the "guts of the microwave are").

        One way mirror wouldn't really work... those require the obscured side to be in relative darkness. Basically, a one way mirror simply reflects enough light that the images of objects behind it are washed out. An OLED screen would put out enough light to be visible.
