Lenovo’s press release calls the Yoga Book 9i the “first full-size dual screen OLED laptop” among vendors selling at least 1 million units a year. Targeting creative consumers who also want a machine with strong productivity that’s also fit for entertainment, the laptop has two 13.3-inch OLED panels connected by the soundbar hinge that Lenovo has been using in its Yoga convertible lineup for a while.
Each OLED screen has 2880×1800 pixels in a 16:10 aspect ratio. That’s 255.36 pixels per inch (ppi) for each panel and 10,368,000 pixels total. That’s 12.5 to 25 percent more total pixels than a 4K screen, depending on whether it’s 16:9 or 16:10.
