This comes not long after HDTV Test shared images of an LG OLED TV showing signs of screen burn while on display in a retail store.

This seemed to be supported by an article released by ZDNet reporting the sales of LG Display, the world’s largest LCD maker, have plummeted, leaving the company in distress. The impartial tests seem to prove that Samsung’s QLED and Dynamic Crystal Colour UHD TVs aren’t susceptible to screen burn like other TVs and potentially monitors on the market. As such, Samsung QLED and LED TV sets have received a perfect score (10/10) for image retention in RTINGS’ test. Samsung claims that its QLED TV picture quality lasts for the lifetime of the product, without any visible deterioration in colour over time, due to the advanced Quantum dot technology – QLED uses inorganic Quantum dot material, which is known to be durable and stays burn-in free. It is for this reason in part that Samsung decided to stop using OLED technology in its TVs in 2012 and proceeded to develop the new QLED technology. The organic material in OLED TVs (OLED stands for “Organic Light Emitting Diode”) potentially wears out over time. After 4000 hours, the TVs testing this content displayed the mark of these logos on screen, even when the content was no longer being played. The tests found that the TVs were most affected by burn-in when they were set to maximum brightness and were showing gaming content and news channels, as both types of content often feature static graphics on screen. The channels and content were respectively displayed in intervals of a five-hour ‘on’ period and one-hour ‘off’ period during a cycle that was repeated four times per day. During the testing period, the technology reviewers assessed and reported on the screens’ brightness and colour renderings every two weeks. The latest reports by RTINGS tested OLED for burn-in on a variety of content, from news and general TV to sports and gaming. These might take the form of static graphics that stay on the screen when running timecode, watching news channels or playing video games. Screen burn, also called burn-in, refers to an effect where part of an image that is no longer displayed is still visible over subsequent images. That’s much faster than anyone previously expected in OLED TVs. Our sister title Definition magazine recently investigated screen burn and discovered that tests by influential technology reviews site RTINGS found screen burn can set in as quickly as two years after buying a new OLED television or, by association, an OLED monitor. But if you’ve ever left your favourite Game of Thrones episode on pause a little too long and then been met with a ghostly figure remaining on screen after pressing play, you have been exposed to “screen burn”. The wonders of technology – and the simple pleasure of being able to pause, rewind and record TV – makes consuming media a smooth experience these days.

The younger generation won’t recall the desperation and panic of trying to fit in a toilet break, make a cup of tea and grab the snacks, all within the three-minute commercial break in the middle of a favourite TV programme. RTINGS is continuing the LG OLED C7 TV tests and updates its tests weekly.As LG OLED TV slows and reports surface of screen burn on in-store display models, we investigate this pesky phenomenon and if a solution can be found LG certainly isn’t the only company that has had issues with screen burn-in on OLED devices Google had a burn-in issue with its Pixel 2 XL when it was first released last year. The big take away here is to vary the content you watch on your OLED TV and be sure you don't run it with the same network logo or map on it each time you turn it on. LG, however, claims burn-in won't be an issue for at least 30,000 hours.

The TVs that played gaming and news content had burn-in that left logos on the screen constantly after only 4,000 hours of use. The tests conducted were also run on the TVs at different brightness levels. RTINGS admits that its test scenarios are extreme, but anyone who likes to watch channels with a permanent news ticker, The Weather Channel, or plays Battlefield all the time can certainly match this test in real-world usage at home. Something interesting was discovered during testing the worst type of content for causing burn-in was gaming and news of the sort that leaves static logos or maps on the screen all the time. This playback regime was designed to simulate watching the TV for five hours per day. The test regime took the six TVs and ran through them different types of content for 20 hours per day with an hour of rest between each five-hour block. The testing is still ongoing as of this writing, but already the publication reports that the TVs have burn-in that is worse with certain types of content.
