Core Viewpoint - LG Display proposed a simplified tandem OLED technology to Apple, which could potentially be used in future iPhone models, but any implementation is unlikely before 2028 [1][3]. Group 1: Technology Overview - The simplified tandem OLED technology involves stacking the blue sub-pixels in two layers while keeping the red and green sub-pixels in a single layer, enhancing efficiency and reducing power consumption [1][2]. - Current iPhone OLED screens utilize a single-layer stacking method for RGB sub-pixels, while the proposed technology aims to improve brightness and battery life [1]. Group 2: Competitive Landscape - LG Display has been more proactive in proposing tandem OLED technology to Apple compared to Samsung Display, which is reportedly lagging in this area [5]. - Apple has previously adopted dual tandem OLED technology for its iPad, indicating a willingness to explore advanced OLED solutions in its product lineup [2][3]. Group 3: Supply Chain Dynamics - Apple is likely to engage multiple suppliers, including Samsung Display and BOE, to maintain negotiation leverage and avoid dependency on a single manufacturer [5]. - In 2024, LG Display is expected to supply more OLED panels for iPads than Samsung Display, reflecting its growing role in Apple's supply chain [3].
