The 2022 iPad Air is expected to feature an OLED panel unlike last year’s model which has an LCD display
Mini-LED delivers improved contrast (a million to one contrast ratio), outstanding viewing angles, deeper blacks, and 1,600 nits peak brightness. The LEDs used to backlight the LCD panel are 120 times smaller than the ones used with a traditional LCD screen. As a result, 10,000 mini-LEDs are used on the 12.9-inch iPad Pro (2021) compared with the 72 LED components used on the 2020 12.9-inch iPad Pro.
Samsung is also believed to be updating its OLED production technology which will use dry etching as opposed to wet etching. This process is said to be better when producing OLED panels larger than 10-inches. Add this to the news that Samsung is expecting Apple to place orders for these larger screens and it all seems to indicate that the latest production technology will be used to make screens for the iPad.
