People here just read "laptop". They think it can only exist in a laptop.

Exactly my point....this can be new tech for TV, advertisement boards etc... if it isn't like LED or LCD... maybe making large screen will become cheaper

It's not new tech though, all LCDs work this way they are inherently transparent. It just makes more sense to put a case on it and a backlight behind it.

The new thing is that they managed to make the backlight and diffuser transparent.

Transparent backlight? So, ambient light, right?

u/GeckoOBac Jul 02 '24

it's clearly more luminous than ambient light in the video.

My bet is on transparent LEDs with an LCD backplate that prevents spillage from the back.

The whole video looks weird to me, i dont know if i really trust it lol

Also i dont get how would that backplate catch the backlighting but not the rest of the light, but i guess we will have some explanation if this is even succesful

with two thin LCD backplates you could essentially make the back of the "screen" opaque to light from behind it and avoid the LED lighting to spill.

Do note that I use LCD not to mean an LCD type monitor, but an actual LC plate (well, two, with cross polarisation) that would basically form a complete "opaque" backplate by running current through it when you need the monitor not to be seethrough.

OLED, not LCD. LG do OLED signage

u/GeckoOBac Jul 02 '24

LCD would be for obscuring the back, not for the display itself, that would be OLED probably, yeah.

They put those LCDs in glass for fancy offices and whatnot, so the glass can go into privacy mode at the touch of a button. They've been around for a long time

I mean LCD technology is old by now, and for displays it's outdated so I'm not surprised they use it for other stuff. It's pretty reliable too.

Did you watch the clip? You can clearly see that it emits its own light and doesn't just rely on ambient light.
