Apple may finally have a way around the OLED iMac’s biggest problem, though it’s still years from shipping
LG Display's new OLED approach targets the burn-in problem that's kept OLED out of the iMac for years, not just a brightness upgrade.
Apple may have found a solution to OLED burn-in problems for the iMac, but it is still years away from shipping. OLED panels on desktop displays face issues due to static menu bars and docks that cause burn-in. LG Display has developed a panel technology that addresses this concern. The company's four-layer OLED panels, already used in high-end monitors, stack light-emitting layers in a blue-green-blue-red pattern.
A breakthrough is the addition of a second blue layer, which spreads electrical current across more emitters, reducing the stress on individual emitters and improving brightness and long-term durability. Apple reportedly requested panels with 600 nits brightness and 218 pixels per inch, an upgrade from the current LCD iMac's 500-nit ceiling.
However, Apple's priority is currently durability, not brightness. Development is expected to be completed by 2028, and an actual OLED iMac might not launch until 2029. The complexity of manufacturing at this level increases costs. Apple is likely to refresh its existing LCD iMac with a new chip instead. Meanwhile, unrelated news about AI companies OpenAI, Anthropic, and SpaceX's impact on Cursor's operations is ongoing.
