Rtings.com tests show serious burn-in in LG's OLED TVs after only 4,000 hours of use

Review web site Rtings.com has performed an extensive burn-in trial for LG's 2017 OLEDC7 OLED TV models, and reports that the TVs have shown signs of permanent image-retention, or burn-in after only 4,000 hours.

Rtings have used six OLED TVs, running them from January 2018 for 5 hours each day at a time followed by one hour when the TVs are turned off. This cycle was run 4 times a day. One TV was at maximum brightness, and the rest at only 200 nits. Some played CNN, some a gaming title (FIFA 2018) and some of the TVs played regular TV channels. The TV that played CNN had a clear logo and static bar burn-in images, and the same goes for the FIFA game (but only slightly). The regular TV programs did not suffer from any burn-in.

LG replaces the OLED TV at Incheon airport to an LCD due to burn-in issues

Only four months after LG installed 69 OLED TVs at Seoul's Incheon Airport it was reported that the TVs suffer serious permanent image-retention, or burn-in. ZDNet now reports that LG replaced the problematic OLED TVs at the airport's Korean Air Miler Club Lounge with LCDs.

The report suggests that LG was not sure it could solve the burn-in issues with this particular display, and so opted for an LCD. LG denies that burn-in is a serious issues and says the TVs's lifetime are over 30,000 hours.

ZDNet: LG's OLED TVs at Incheon airport suffer from serious burn-in

According to a ZDNet report, the LG OLED TVs at Incheon Airport, installed only a few months ago, suffer from serious permanent image-retention, or burn-in. You can see the artifact at the top part of the TV in the photo below:

According to ZDNet, LG installed 29 such OLED TVs at the airport lobby in addition to 40 more units at four of the airport's lounges. These were installed in January 2018, only four months ago. LG Electronics did not comment on this story.

Apple's iPhone wins burn-in test over Samsung's flagship OLED phones

Korea's Cetizen posted an interesting review of the burn-in of 3 flagship OLED phones, the iPhone X, the S7 Edge and the Note 8. Cetizen displayed the same image on all three phones for 510 hours (!) at full brightness.

As you can see in the image above, the Note 8 has very visible burn-in, while the two other phones perform better. Cetizen say that the iPhone has the best display in that regard. Apple did in fact confirm that the iPhone X suffers from burn in, but also said that it engineered the display to be the best in the industry in reducing the effect of OLED burn-in, though - and apparently this engineering works.

Apple admits that burn-in could occur in the iPhone X OLED

Following the launch of LG's pOLED displays, we had many recent discussions and reports of OLED burn-in and Image-Retention. Apple now released a support document for the iPhone X, its first OLED phones, in which it warns users that “image persistence” or “burn-in” is an "expected behavior".

Apple says it engineered the display to be the best in the industry in reducing the effect of OLED burn-in, though. Apple also says that its OLED could have noticeable but slight shifts in color and hue when seen off-angle. The iPhone X has a 5.8" 1125x2436 Samsung-made Super AMOLED display.

Google responds to user complains on the Pixel 2 XL display

Google started shipping its Pixel 2 XL smartphone a few weeks ago, and this is one of the first two phones to adopt LG Display's new 6" 1440x2880 (538 PPI) pOLEDs. While on paper these displays are superb, actual reviews were rather dismal - to the point that some reviewers say that these are simply "bad displays".

Both reviewers and customers complain about bad color reproduction, graininess and problematic viewing angles. In addition many users seem to report serious image retention issues. Google has now posted an update regarding the Pixel 2 XL display.

On Burn-In vs Image-Retention and LG's new pOLED displays

In September 2017 LG Display started shipping its new 6" 1440x2880 (538 PPI) pOLED displays, which are adopted so far by two smartphones - the LG V30 and Google's Pixel 2 XL. On paper these displays are superb, but actual reviews were rather dismal - to the point that some reviewers say that these are simply "bad displays".

The reviews mentioned bad color reproduction, graininess and problematic viewing angles - and many consumers also reported serious burn-in issues. Samsung has recently started a marketing campaign that says that LG OLED TVs also suffer from image retention problems. In this article we'll explain what is burn-in, the difference between burn-in and temporal image-retention and also try to shed some light on LG's latest OLED problems.

The soft home button of the Galaxy S8 moves around to avoid burn-in

Image retention ("Burn in") is one of the major drawbacks of OLED displays, and a static icon or very consistent displays are always a problem with such displays. When Samsung introduced the Galaxy S8 it implemented a soft home button, which caused some concerns.

PhoneArena confirm that Samsung's home button actually moves around by a few pixels from time to time - obviously to prevent serious image retention. Samsung employed the same trick with its "always on" clock display in previous OLED phones. This is a good way to improve image retention - although it won't solve the problem completely as the icon only moves around by a few pixels each time.

LGD to use Ignis' circuit technology to enhance the performance of its OLED displays

IGNIS Innovation announced that it has signed a non-exclusive patent license agreement with LG Display. Ignis will provide LGD with access to its circuit technology to enhance the performance of OLED displays.

Ignis Innovation developed several OLED circuit technologies. It's basic technology involves OLED compensation, both external and internal - which can improve the power consumption and lifetime of OLED displays. The technology should also increase production yields and enhance the picture uniformity and stability.
