The tech giant launched its first Pixel phones toward the end of 2016 with 5-inch and 5.5-inch OLED displays. The phones were well received, but the panels needed to make the phones are in short supply and not always easy to come by in big quantities. Google is reportedly hoping to avoid shortages in the future by investing in the tech.
LG Displays makes the most money on OLED producing larger displays for TVs, but Google's investment would help it create a dedicated production line for small and medium-sized OLED displays that should guarantee better supply next time around. It would also guarantee Google priority when it comes to getting the number of screens it needs.
Google and LG Display did not immediately respond to requests for comment.
