LG OLED Image Retention/Screen Burn
« on: November 30, 2017, 18:11:41 PM »
Hi folks, I've recently been doing some research on potentially upgrading my aging but perfectly adequate 10 year old 50' Panasonic Vierra Plasma.

I've narrowed my preference thus far down to 2 models; LG OLED55B7V which gets top marks in the latest Which survey and is the number 1 Which best buy https://www.richersounds.com/lg-oled55b7v.html

or
Samsung QE55Q7F which also gets excellent reviews and comes 2nd spot in the Which tests https://www.richersounds.com/samsung-qe55q7f-hwm360.html?nosto=productpage-nosto-1

I was leaning towards the LG but have been reading some horror stories on AV Forums about people watching eg Sky News/Sky Sports News/ BBC News etc. or indeed any channel with static banners and they have resulted in permanent image retention which the TV's in built cleansing technology cannot resolve. The warranty offered by both the retailer and LG doesn't cover screen burn which concerns me somewhat especially as I watch a fair amount of channels with these banners.

I don't think that this problem is exclusive to LG panels but it appears to be an issue with all manufacturers OLED screens. Samsung do not seem to have this issue as they do not produce OLED screens and LED do not have this problem to anywhere near the same degree.

I'd be interested to hear if any of you OLED owners have experienced any problems or heard about these issues? All replies would be welcome but especially Ron and Keith. :)

Hi Chris - First off LG are pretty much the only manufacturer of OLED panels - the Sony A1's have LG OLED panels and so does the Panasonic range as LG own the factory that produces them. It's what each manufacturers do with the panel by adding additional technology which is the key. I know the Sony A1's have a cleaning cycle and the LG ones have something similar - most have settings called something like screen shift which momentarily moves the image on the screen fractionally to prevent an image being static. I wouldn't be surprised if some of this screen burn stuff is coming from Samsung who are finding it hard to compete with their QLED against OLED but they are a bit stuck as can't see them wanting to buy LG Panels as they are Korean rivals!!
Personally a choice between an OLED and QLED is a no brainer - the QLED in my opinion is awful and I have seen side by side comparisons with the LG OLED/Sony OLED/Samsung QLED and the OLED's are by far the more superior. Samsung's panels just love to pump the colour up so much that images look either burnt out or unrealistic, there are few shades and subtleties evident.


I guess the reason they won't guarantee against screen burn is that potentially with the wrong image at intense brightness any screen panel can be damaged this way - but I think for general use there is not much of an issue. Plasma screens were notorious for screen burn so if you are watching stuff now on a Plasma and not getting screen burn then OLED should be fine.


Given the choice I would buy the Sony A1  ;)  - cash back offers now on....0% interest free credit and 5 year guarantee at John Lewis  ;D

I had a Samsung phone with OLED screen and I must say for that application it was superb. But bog standard LED panels are so much better than they were 10 years ago when I bought my first HD telly.

I have a 50-inch ISIS model at the moment that's pretty good bar the sound (I overcame that with a decent amp and outboard speakers).

Thinking of upgrading to a bigger screen, unfortunately all the 60-inchers I can find seem to be 4K, which is pure snake oil unless you're going to pull your chair right up to the telly.

I have a 4K TV and sitting in the same position for regular TV, 4K content even on an internet stream via YouTube/Netflix or Amazon Prime the upscale quality is fantastic.
This myth you need to have your nose on the screen to actually see a difference is ridiculous. I would admit there is a lot of over marketing for both 4K and HDR on current TV's especially as there is still a distinct lack of content but seeing 4K content on a 4K screen is marked improvement to HD - if you think otherwise get yourself booked into spec savers  ;)

Are you the sort of person who could read a newspaper pinned to a wall 15 feet away, Keith? Impressive if so.

For someone with human vision, you'd need to be sitting within about 4 ft or so of the screen to see an improvement in detail on a 60" 4K TV.

I was looking at a Samsung QLED as a possibility for the new kitchen - which is going to be flooded with Natural light.....are we thinking OLED is a better option?

I would have thought that OLED would be a better option - because the pixel points actually emit light, they don't have to be backlit. I'd think that an image that has to be backlit would struggle in a very bright room. But:
QLED is brighter. The brightest QLED and LCD TVs can get brighter than any OLED model, which is a particular advantagein bright rooms and with HDR content. In my tests, however, OLED TVs can still get plenty bright for most rooms, and theirsuperior contrast still allows them to deliver a better overall HDR image than any QLED/LCD TV I've tested.

Not sure how big a screen you were looking for but doubt you'd find an OLED below 55" - big kitchen if you can take a 55" - current Panel Makers for OLED produce 55/65/77" sizes.


Have just been reading some of the selling features on the latest 2019 Samsung range - one is : Colour Volume 100%   :o ::) :P  would love to know what this actually means and what the % measurement is measured against....??  don't you just love marketing.

Been tracking a Sony 55" AF8 OLED for a few months for the price to drop as I don't actually need it until the end of May...price had dropped another £100 in the last couple of days and the local department store has a 10% off Home Event this weekend....checked it out in the flesh again yesterday....and caught sight of the LG C8, which is £300 cheaper and looks pretty amazing...seems spectacular value to me...taking the plunge today...

How is the 55 C8 then Hass? I have still not taken the plunge but have my eye on the C8 65 inch which is now just under £2k or the Samsung 65 Q9FN which is around the same price. Image retention still concerns me with OLED :-\

Got delivered yesterday but is unlikely to be hung for around 2 weeks.  We are into the 17th week of a major kitchen refurb (thank god mum lives 5 minutes away)...should all be done in the next fortnight.

I thought it was a beautiful TV though.  Picture quality was jaw dropping and it received brilliant reviews...
