Flatscreen tellys that can display still images for long periods of time

londonTiger

Wanting to buy some tellys for business use so I can display still images on it for long period of time.

Things like website, PC display, powerpoint etc.

Might have a still image on for up to 8 hours.

Anyone know if modern LED flatscreens suffer from plasma burn?

Thanks

Well since they are not plasmas then they won't suffer plasma burn.

I suspect the only thing to watch out for is if the pixels get "stuck" by being set to a single state for an extended period. But in this is probably unlikely.

Ok thanks. That's what I was referring to. Most tellys have issues with displaying still images for long periods of time don't think? Or are they all built like computer monitors nowadays?

The term LED* when linked with flats screen television most likely links to the rear , white light, illumination of an LCD panel. This was previously done by fluorescent tube strip lighting.

LCD 'screen burn' will happen if a persistent image is displayed over a long period on time.

We tend not to notice things that are unchanging and learn to ignore static and over repetitive items in a matter of minutes. I am sure that if the information content is refreshed and the position of it shifted then the display will attract interest and have a longer life.

Walk into any bookies and look at the screens
Lots still use standard LCDs and plasmas without issue, they're on [some on static images] from 9 till 9

Shop refits have all tended to move to monitors now because they're cheaper

Plasmas have got a lot better with screen burn and it's not an issue in normal use. This isn't normal use though.
LED/LCD screens CAN suffer from retention (retention means image remains for a while, burn means it never goes away) and stuck pixels as above. Buying a monitor won't make any difference, it still has the same pixels.
I would guess you have to risk buying an LED/LCD TV and replace it down the line if it does get damaged, or spend a lot more money on more professional displays that may guarantee no damage.

Thanks for the reply. I suppose if the TVs are built using the exact same tech as on monitors then the risk of stuck pixles will be really low?

On computers the GUI are always displayed and probably set to on position for 8-10 hours a day and they don't seem to suffer from stuck pixels.

I've no idea what the actual chance of a stuck pixel is. But I'm now on my third TV as each of the first two developed a stuck pixel.

I would think that the most important aspect of any monitor or tv being used for the purposes you describe would be viewing angle?

No point in having any display if you can't view the picture properly.

LCD Monitors aren't different to LCD TVs. Ever heard of screen savers? Ever wonder what they're for? (they SAVE the SCREEN from burn in!). Originally designed for CRT screens but still relevant to plasma and LCD.

AMOLED screens do indeed suffer screen burn, many phone users are noticing this on modern handsets. Leaving an image on this type of screen all day will result in a ghosting problem.

This is absolutely nothing to do with dead/stuck pixels - which are elements which fail and retain on a specific RGB colour.
