Solas files a lawsuit against Apple saying it infringes upon its OLED patents

Ireland-based OLED IP company Solas OLED has filed a lawsuit in the US (Texas) against Apple for patent infringements. The lawsuit mentions three patents (USPTO# 6072450, 7446338 and 7573068) that relate to the OLED stack, structure and circuitry (for example one of the patents relates to the formation of a backplane on a polyimide substrate).

Apple is of course not the producer of the OLED displays - but Solas says that Apple is accused of "making, using, selling, offering for sale, or importing products that infringe the claims" of its patents. Apple's OLED suppliers are Samsung (for the iPhone and MacBook Pro Touch bar devices) and LG Display (for the Apple Watch display).

LG Display starts to use Korean-made hydrogen fluoride in its OLED fabs as Japan restricts exports

According to a new report in Korea, as the OLED industry does not require an extremely high purity hydrogen fluoride and LG has been able to quickly find a source for this gas in Korea. It already started to use the Korean material in production - and aims to source 100% of its hydrogen fluoride from Korean vendors.

LG delays the launch of its rollable OLED TV

In early 2019 LG Electronics announced the world's first rollable OLED TV, the 65" Signature OLED TV R. The company later announced that it will ship the TV in the second half of 2019, but now LG is delaying the launch of its signature rollable OLED TV.

LG says that the OLED TV R will ship in Korea in "2019 or 2020", but that consumers elsewhere will have to wait longer - which probably means it does not have any plans to release it before 2021. According to TechRadar, the main reason is that LG is highly expensive and LG fears that it will be difficult to find a market outside of Korea for such a premium TV.

HDTVTest: OLED TV burn-in is highly unlikely if you vary your content

OLED Displays burn-in has always been an interesting topic, with some users and reviewers complaining about serious burn-in issues in some of their OLED TVs, while others report of no visible issues. UK based HDTVTest performed a comprehensive 6-month test on a brand new LG E8 OLED TV and found no sign of permanent burn-in.

HDTVTest says that they displayed varying content for 20 hours a day for more than 6 months (a total of over 3,700 hours). They also suggest to put the TV in standby mode rather than complete power-off so that the compensation cycles can run.
