back to article Xiaomi turns 10 and celebrates by sitting down to relax in front of its new transparent television

Chinese consumer goods manufacturer Xiaomi has celebrated its tenth birthday with the release of a transparent television. The 55-inch Mi TV LUX offers a substantial cylindrical base, a metal bezel and - at a glance - not much else. Xiaomi has offered some verbiage about the tellie making images appear to float in a virtual …

    Frying tonite

    > 120w wired charging said to fill the 3500Mah battery in 23 minutes

    120 Watts for 23 minutes sounds like a hell of a lot of power to fill a piddling little 3.7V 3.5Ah battery.

    The energy from the charger comes to 2760 Watt*minutes, while the capacity of the battery is 3.7 * 3.5 * 60 = 770 Watt*minutes. Does the other 2000 just cook the battery?

      Re: Frying tonite

      I dunno, do considerations of efficiency change the sums at all? Is 120W the max the charger will draw from the socket but not what it supplies to the phone?

      Re: Frying tonite

      I am going to guess it is capable only of 120W charging when the battery is basically empty.

      The actual spec says 41% charged in 5 minutes, laws of physics will interfere and I imagine it just gets scaled down and throttled very quickly, probably with added thermal monitoring.

      Curiously, it claims this is a new kind of "graphene" based Li-Ion battery..?

        Re: Frying tonite

        Search for 'graphene anodes' and you'll find a lot of articles and papers. You'll have to dig more deeply than I have to find out how close to production they might be.

      No charging for conventional batteries is linear.

    Transparent phone, please?

    With the battery and heavier electronics at the bottom so it's more comfortable to hold in one hand.

      Re: Transparent phone, please?

      We're forever seeing see-thru phones in sci-fi, films like Looper, TV like the Expanse. I never saw the point. And back in our reality, there were some see thru dumbphones on the market a few years back, with boring old monochrome see-thru LCD panels.

      Sci Fi Side note: the origami folding tablet things from Westworld appear to be useful.

        I guess they'll be useful for AR, point your phone at something, the camera works out what it's being pointed at and then overlays on screen the details.

        Being able to just see the innards of your phone is pointless, but I imagine they'll be a few nice AR things down the line.

        But otherwise, yeah, not much point, and a whole TV, don't really care for that being see through when it's off..

          Re: Transparent phone, please?

          If the camera can work out what it is being pointed at, it can simply DISPLAY what it is being pointed at without making it transparent.

          Transparent phones/TVs are stupid. They "look cool" but in actual use would be a disaster. It either needs to invent a black OLED cell, or you'll always see the HDMI and power cables through your TV in low light scenes. Not so cool now!

          I just had a look behind my telly. No way in hell do I want that dusty tangled mess of cables in view either through an active display or through a clear glass turned off screen!!!!

    Transparent TV?

    No thank you.

      Re: Transparent TV

      I'm wondering how it creates black pixels and handles high contrast scenes. Perhaps there's an LCD layer that kicks in to block light from behind the screen. But absence of emitted light from a pixel isn't quite the same as a true black pixel.

        Re: Transparent TV

        I'm wondering how it tells a pixel is transparent... are these "normally black" pixels?

          > I'm wondering how it tells a pixel is transparent... are these "normally black" pixels?

          Other sources say the TV comes with some custom content, to give the impression of fish swimming about etc. It's likely that you can play PNGs with transparency defined by an alpha layer, too.

          Otherwise, it just plays normal video in a normal fashion.

      Wondering what it looks like when viewed from behind.

      Also if it would effectively project a blurred mirror image of the picture on the back wall.

      Or is it like a rainbow, only visible from one side?

      Heh. Barring the wall mount, I also have these; as well as a few old dvd's, some Lotr lego, and a selection of physics textbooks [1]

      [1] I wondered where they'd got to :-)

    Samsung demoed this a while back

    And the demo included making use of the transparency for effects including playing games with people on different sides of the TV. IIRC, which I probably don't. Otherwise informational displays, window display, etc.

      One pub I was in recently had a sheet of perspex running down the centre of a long table... Apparently drinkers had a game of Battleships on it on their first night of reopening, as one might have expected they would.

      Possible a see-through fridge door that is also a display screen? eg retail fridges with cans of pop etc.

    So we can now have the viewport & have it function as a display as seen on NCC1701.

    WTF?

    Transparent TV? Ridiculuous idea...

    If you really must have one, stick a camera on the back and show that...

    But really, WTF? The idea of a TV is to show an image, not to show an image cluttered up with whatever is behind it. Maybe it works in some (theoretical) CEO's enormous and sparsely decorated office, if it's perched in the middle miles from anything which might be close to the focal plane - but to be honest, this sounds as useful as transparent panels on a computer desktop. Let's not see what we popped the window up to see, but with added blur, confusion, and general visual noise from whatever's behind it.
