LG Display reportedly developing its first 5-layer OLED for TVs, iMac

Up from the 4 emitting layers used in today's most advanced Tandem WOLED panels, a 5-layer panel could deliver higher brightness and longer lifespan.

LG Display is seemingly looking to expand in both directions. The company recently said that it has developed a 2-layer OLED panel for mid-range TVs and monitors, down from the 3 layers used in standard WOLED panels today. This would make the panels cheaper to produce.

However, it is also developing a 5-layer OLED panel, up from the 4 emitting layers used in today's high-end Tandem WOLED panels, used in TVs like LG G5 and Philips OLED911, according to a report by Korean newspaper The Elec. This would offer higher brightness and longer lifespan, but would also be more expensive to produce.


For Apple iMac, TVs and monitors
According to The Elec, the panel is being developed as a next-generation OLED display for Apple's iMac, and potentially TVs and PC monitors too.

LG Display had already developed a 4-stack 27-inch 5K (5120×2880) RGB-stripe OLED, which is a candidate for a future Apple iMac. However, Apple has apparently tasked both LG Display and Samsung Display with developing even higher-performance panels for its first OLED iMac, planned for 2029.

Samsung Display's latest Penta Tandem QD-OLED panels already use five emitting layers, up from four in 2024.
