Cupertino, California – august 4, 2025 – Apple is poised too significantly enhance iPhone display technology, planning to integrate ‘Tandem’ stacked OLED displays as early as 2028, according to a report by The Elec. This move will bring a key feature currently exclusive to the iPad Pro (M4 chip) to future iPhone models.
The transition to Tandem OLED technology, which doubles the number of organic layers in the display, promises increased brightness, improved energy efficiency, and extended display lifespan. Current OLED displays utilize a single layer of red, green, and blue light-emitting diodes. Tandem OLEDs employ two layers, boosting luminance without increasing power consumption.
Apple has reportedly established a two-year production timeline for the switch, beginning with initial implementation targeted for iPhone models launching in the latter half of 2028. The company is currently evaluating potential manufacturing partners, with both Samsung Display and LG Display vying for the contract. A decision has not yet been finalized regarding which company, or companies, will supply the panels.
Apple is initially focusing on a “simplified Tandem” approach, layering the blue OLED pixels while maintaining single layers for red and green. This strategy, known within the industry, aims to optimize cost and manufacturing complexity. LG Display previously proposed this simplified Tandem OLED solution to Apple, leveraging its existing technology and supplier relationship.
While Samsung Display currently leads in overall OLED panel production, LG Display has reportedly made significant strides in Tandem OLED growth, possibly giving them an edge in securing the Apple contract. Though, Apple is expected to diversify its supplier base, potentially including Chinese manufacturer BOE, to ensure sufficient production capacity and competitive pricing. BOE currently supplies OLED panels for some iPhone models, with production facilities located in Chengdu, China.
The adoption of Tandem OLED technology represents a substantial investment in display innovation by Apple,building upon advancements first seen in the 11-inch and 12.9-inch iPad Pro models released in may 2024. These iPad Pro models, featuring the M4 chip, showcase the benefits of Tandem OLED, including a peak brightness of up to 1,600 nits for HDR content and improved color accuracy.The move to Tandem OLED for iPhones is expected to further differentiate Apple’s devices in a competitive smartphone market.
