Apple May Finally Have a Way Around the OLED iMac’s Biggest Problem, Though It’s Still Years From Shipping
The panel adds a third blue layer to improve brightness and reduce burn-in as Apple weighs 24-inch and 27-inch OLED iMacs.
- Apple is working with LG to source a new 27-inch penta-tandem OLED display for future iMacs, according to Korean news site The Elec, marking a potential shift in the tech giant's all-in-one desktop screen technology.
- The penta-tandem display uses five layers of diodes to enhance screen brightness and durability by spreading electrical current across more emitters, reducing individual stress on each panel component.
- OLED technology offers superior contrast and ink-like blacks because each pixel emits its own light independently, while panels are also thinner and lighter than LCDs, providing consistent brightness at wider viewing angles.
- Manufacturing these complex panels remains costly and technically challenging, so Apple may refresh its existing LCD iMac with a new chip later this year, treating the OLED iMac as a long-term development goal.
- Adding OLED would bring the iMac in line with premium competitors like the 31.5-inch Lenovo Yoga AIO Aura Edition; while the 2024 M4 iMac starts at $1,500, a high-end 27-inch configuration could demand well over $5,000.

OLED iMac Panel Could Include Extra Layer to Fight Screen Burn-In
LG Display is developing a five-layer OLED panel structure that could end up in a future iMac, with an extra layer added to prevent screen burn-in and increase brightness, reports The Elec. LG Display already builds four-stack OLED panels for high-resolution monitors, and arranges the light-emitting layers in a blue-green-blue-red pattern. The five-stack version reportedly under development adds a third blue layer, creating a blue-green-blue-red…
LG Display would currently work on a new five-layer OLED architecture, with a specific objective: to meet Apple's requirements for future iMac OLED potential. This new structure would adopt a B-G-B-R-B stacking, with three blue emitters, a green and a red. By comparison, the high-resolution Tandem OLED technology currently developed by LG Display is based on four layers organized in B-G-B-R. The addition of a third blue layer could increase brig…
Apple is preparing a future iMac equipped with a five-layer OLED screen to avoid burn-in issues. This technical challenge pushes its release back to 2029.
