Overview

• LG Display is lobbying Apple to bring tandem OLED to iPhones targeted for 2028, according to Korean industry reports.
• Tandem OLED stacks two emission layers to raise brightness, improve power efficiency, and extend display lifespan compared with today’s single‑stack iPhone panels.
• Apple has reviewed a “simplified tandem” approach that doubles only the blue subpixel layer to reduce complexity and cost, prior reports indicate.
• LG is preparing investments to counter reduced manufacturing throughput from stacked layers, while any rollout would likely tap Samsung and BOE to ensure volume and price competition.
• LG leads tandem OLED intellectual property and supplied about 65% of M4 iPad Pro panels, and BOE has already shipped tandem phone displays for Honor’s Magic6 Porsche model.
