Samsung shows off rollable and foldable displays, suggests they'll arrive in 2022 Samsung has revealed foldable and rollable displays at the Society for Information Display (SID) annual exhibition. Organic light-emitting diodes are the key to the new devices, because displays built using the tech don't need a backlight. The result is paper-thin and flexible panels. Samsung’s star item was the "S-foldable" …
For large areas projectors are almost always going to be preferable to panels. It's simple maths: either you need lots more pixel (x * n) or bigger ones. Projectors just need stronger light sources.
However, panels are getting better at being combined together for display purposers.
I'd prefer a projector with a 3:1 zoom lens. Largest size (72") only for > 2.5:1 aspect ratio high quality cinema content and smallest size for talking head news and maybe old VHS.
Very few projectors seem to have zoom lens and few are better than 1920 x 1080. They seem to be mostly made for power point. Also single chip DLP have the colour wheel that can fail or cause a rainbow effect if you wiggle your head.
So I've been not buying a projector for 10 years. I don't want a 65" screen (roll up or not) for most content. Room too small and most is 1.85:1, 16:9 or 4:3. Some is 1.66:1, so a projector, Zoom lens and adjustable side matte on a projection screen is best.
With a webcam in the bezel you can have a shutter or other way to physically block it - once it is somewhere behind the screen (a) will you know exactly where and (b) how can you block it?
Phones have a solution to this, even if not elegant, but you could put a small sticker over the selfie cam if needed...

Similarly why I am personally not real fan of 'bezel-less' screens. Why would I want the visual noise of the other side of my office's bookcase right up against the thing I am reading?
Unless they could make the background black, transparent screens is cranking this to eleven. But, can't wait until Samsung's and Apple's marketing team tells us all this is what is actually popular and everyone falls into lockstep and that is all we'll get.
Correct, not as a replacement for a traditional screen, but there are use cases (including HUD for cars where I think there are already some examples - sorry no citation) and the sensible ways of using such tech will come along once we have it. Remember how going from CRTs to LCDs meant there were now ways to do something not possible before...
Creating a HUD on your car's windshield is already elegantly easy. All you need to do is place a standard screen on the dashboard facing up. Try it with your phone.
The glass is not perfectly transparent, it will always reflect some light like a mirror. As long as the light source is slightly brighter than surrounding environment, you will see the faded, slightly transparent screen image hovering in the middle of your windshield.
I know some production cars already use this to display speed, and I've even seen one that shows GPS directions (as a red line) as an overlay on the real road. Not sure why it isn't more widely used, perhaps could be seen as a driver distraction, or obfuscates the driver's view of the road.
