Actual LED TVs? do they exist?

Started by Commander Kinsey July 27, 2020
Are any TVs just LED?   Or is LED just a backlight to an LCD panel?  I thought they'd invented TVs where every dot was a tricolour LED, but I can't find any such thing.

As Phil implied by his link, their are organic LEDs (OLED) display TVs on the market. Many at consumer friendly prices (<$3000). As a display device hey can perform very well. Inorganic LEDs are use in commercial displays, i.e. all over Times Square NYC. At the other end of the scale are micro LEDs. They exist in special idustry for near-to-eye displays (military applications). A consmuer-ish "pseudo micro LED" was demo'ed at CES once by Sony. a Prototype so far.

$3000 is not consumer friendly! Or are you talking about a 70 inch screen?!

There's some difficulty with non-organic LEDs being SO hard to make three colors, but this projector-compatible item shows that there is some progress being made <https://youtu.be/52ogQS6QKxc>

** Yep - highly efficient white ones.

** No fooling ? TV screens are intended for indoor use in subdued light - get yourself a Lux meter and see how the difference is HUGE like 1000s to 1. Large LED screens have long existed and are used outdoors, as are LED traffic lights. Horses for courses ... ..... Phil

You're incorrect, I found OLED.

Not very efficient when you block half the light with the LCD in front of it.

Do you mean "no kidding"?
> TV screens are intended for indoor use in subdued light
Really? Do you shut the curtains when you watch TV? I don't. That's only needed for cheap shit projectors.

Difference between what and what?

Really? You can buy LEDs of red green and blue pretty easily.

What would those be used for? TV inside glasses right next to your eye? Otherwise I don't think your eye can detect 10,000 dpi.

Don't be so rude, I didn't know the term "OLED".
