LG Display is reportedly developing 5-stack OLED panels rumored to be headed to the 24-inch iMac, which provide ever better brightness and image quality. While a current 24-inch iMac already has a great display, a 5-stack OLED one would be better and last longer.

Apple is clearly planning to bring OLED displays to all of its devices, potentially with the iPhone 20 Pro getting 2-stack or what the company calls Tandem OLED panels. Back in 2022, Apple was so keen on 2-stack for the iPad that it insisted an initially reluctant Samsung develop the design to ensure a longer life and better image quality.

While previous reports suggested such an iMac might not be produced until 2030, new predictions are fractionally more optimistic, suggesting a launch in 2029. The goal is to achieve a resolution of 218 to 220 pixels per inch, though the complexity and cost of producing such large, high-quality panels remain significant hurdles.
