Backlit vs edge-lit LED TVs

[Dolby]

Nope,not zero chances, but much much less.

So my question is relevant - if everyone is saying that lower brightness helps, does the 30% increase that burn in risk at all

Turning down the brightness (controlled by "OLED Light" on LG's sets, and Brightness on Sonys) will help, especially when you're watching the content that causes the image retention

Wait is it R6.80 an hour worth of electricity or did you include the cost of the tv also?

Just cost of the TV (R34k / 5000 hours).
I used a real-time watt meter and it ranges from 80W during normal viewing and jumps to 300W with high brightness scenes (included the sound though. so not just TV itself).
Average over a whole night of viewing if I recall was around 120W/hr.

Yes of course it will increase burn in risk, but they mitigate that by adding these new features every year.

Agree that it is a valid question and I think you would be correct. But it still depends on the content. Any static image does have temporary image retention. For example. when in Youtube or Netflix menus, when you start a video, you can still see the menu for a couple of seconds. That specific effect is worse if the image is brighter and higher contrast. so I think it is safe to assume for static images (news tickers, game HUD, Windows desktop, etc.) it would be worse.

Linus has a video where he had to run a pixel refresh after 6 months of using an OLED as a monitor (not a TV, proper monitor).

I had a plasma (which was worse with burn-in) for 6 years before buying the OLED and it was still perfect, not a single pixel had a problem and no burn-in at all. Just always keep the burn-in protection on.

I firmly believe that burn-in is a non-issue for 99.9% of people.

Oh that makes sense. I thought it was R6.80 an hour of electricity. I was about to remove Oled from my future shopping cart.

Even if it was, it would still cheaper and better than going to the cinema

 

[The Voice]

Honest question: does anyone make a buying decision based on how much electricity it’s going to cost to run the unit?

Heat sink, pixel shifting/refreshing every 4 hours etc. we are not in 2015 anymore.

OLED burn-in is still a problem.

Real-Life OLED Burn-In Test On 6 TVs

There are concerns about OLED long-term performance due to the possibility of burn-in. We bought 6 LG OLED C7s to play real, non-altered content. It should give you a better idea of what to expect depending on what you watch on your TV.

Thats the C7 though. isnt that a 4 year old tv? a few things have been added since then.

So how has OLED technology changed in the last 4 years?

It's still OLED. Organic LED's degrade over time. There's no avoiding it.

And still really only applicable to static images left on the screen for hours. Also another reason to not watch CNN btw.

oh my goodness.i didn't say burn in doesn't exist anymore.

Heat sinks are a thing now.
They dim static logos.
Pixel refresh.
Screen shift.

All those things help reduce the risk of burn in.

4 or 5 years ago Oleds would start showing signs of burn in within 2 years, but now they last much longer.

Heatsinks don't save OLED displays. Organic LEDs degrade over time with use.

A software update to any of those 4-5 year old TV's will add any of those features you listed.

The technology hasn't changed. OLED is OLED.

Agreed though, burn-in shouldn't be an issue unless you display static content all the time. Also there is only so much you can do with pixel shift as demonstrated in the Rtings.com test, but for the average user burn-in shouldn't be an issue at all.

Once again. i did not say Oleds dont degrade over time. Heat sinks delay the degrading process. Making the tv last longer.

Is this selective reading or am i speaking foreign here?

Yes a software update might add the features but whats the point when the tv has already been used and burn in is already there. Thats why it would be better to get a tv with all those features from new.

So how did this become a topic about oled when the op is about led?

Heat is not what causes OLED's to degrade. It's the emittance of its own light (particularly the UV spectrum) that causes a chemical breakdown and oxidisation of the electroluminescent material used on the semiconductors. Moisture and heat may play a role, but it's not the root cause of OLED degradation.

Eish. Okay then .

 

[TedLasso]

I have the 65" LG OLED CX and brightness has never been a problem.

Concur. In fact it's too bright as it stands. The only thing I hate about my CX65 is how reflective it is. During the day, I need to close curtains not to see reflections.

When the TV is off (during day), I actually use it as an oblique mirror. From from my dining room , I use the reflection to see what my kids are doing in the garden outside the lounge window. It's resolution is great even when turned off

My fault. Sorry

People still love spreading doubt in OLEDs,no one should have any issues with a modern OLED tv.
LED LCDs will have dirty screen effect,light bleed and blooming right out of the box and no one cares. Heres two examples of people with older OLED tvs with no burn in. The newer ones have even more protection measures as said before.
