Earlier this week, LG Display announced that its transparent organic light-emitting diode screen will debut soon. The new technology will be showcased on the MBC broadcasting station’s general elections ballot counting show, which will be hosted on Wednesday (15th April 2020).

For those unaware, transparent OLED panels is the next generation in display technology, which can allow see through screens to become a reality. It allows a person to see beyond the screen, even when the power is turned on. LG Display and LG Electronics had commercialized the transparent OLED panels last year, but this will mark its first commercial debut in a TV show with a high viewership.

According to the company, the transparent OLED technology has a wide field of applications, including installation in shop windows, offices and more, to provide a unique viewing experience. LG Display’s current transparent OLEDs are 55 inch in size with an FHD resolution. These have a transparency of 40 percent, which is a significant improvement over transparent LCD displays that only had a10 percent transparency rate.

In other words, this is the future of OLED displays and may soon see wide adoption in various fields. In the next few years, the technology might even become smaller, allowing for smartphones to feature transparent displays as well. Although, it is still too soon to tell.

Several reviewers have been criticizing the display of the Google Pixel 2 XL citing problems such as strange blue tint and poor color reproduction. A fresh report from Android Central claims that its Pixel 2 XL unit that has been in use since a week has encountered screen burn-in issue.

Screen burn-in is usually associated with OLED screens. It happens when a part of the screen remains longer to create a ghost image even after the screen is changed to view something else. The publication has released the following image of the Pixel 2 XL which shows the screen burn-in where the navigation bar is present.

Image retention or ghosting is another phenomenon that is usually related to LCD panels. It also causes certain portion of the screen to remain longer after viewing something new on the display. However, image retention is temporary, but screen burn-in is permanent.

One should be aware of the fact that screen burn-in can also happen on LCD panels and image retention can also occur on OLED displays. There is a possibility that the Pixel 2 XL’s new problem could be image retention. If it so, the issue may not be permanent.

Apart from Android Central, other leading tech portals like The Verge and 9to5 Google have come across screen burn-in issues on their Pixel 2 XL units. Many OLED panels are known to exhibit burn-in over several months or years. Hence, it is a bit strange to see such an issue to appear so soon on Pixel 2 XL.

Google has reached to The Verge to say that it is already investigating on the issue:

“The Pixel 2 XL screen has been designed with an advanced POLED technology, including QHD+ resolution, wide color gamut, and high contrast ratio for natural and beautiful colors and renderings. We put all of our products through extensive quality testing before launch and in the manufacturing of every unit. We are actively investigating this report.”

In the previous year, when users of original Pixel phones met with burn-in and display issues, they were granted with under warranty replacements immediately. Hence, Pixel 2 XL users who are facing screen burn-in problems could be eligible to receive a warranty replacement. However, it is also advisable to wait for Google to finish its investigation as there is no confirmation on whether the issue is temporary or permanent.
