The iPad Air lineup got a slight upgrade earlier this year with the new 11 and 13 inches models with the Apple M2 chip, but both still featured Liquid Retina IPS LCDs.
A new report out of South Korea claims that the Air lineup will get an OLED display upgrade in 2026. The ElecSamsung Display is touted as the lead supplier for the next-generation iPad Air displays, which will be single-stacked OLED rather than the Tandem OLED seen on the latest iPad Pros.
A previous report from last year also supports the same 2026 timeframe for the iPad Air OLED, and suggests we might see an iPad Mini with an 8.7-inch OLED display as well.
