Guan Cha Zhe Wang·2025-08-11 10:09Core Viewpoint - The adoption of tandem OLED technology by companies like OPPO, vivo, and Xiaomi is expected to enhance display performance and efficiency, following its implementation by Apple, Huawei, and Honor [1][4]. Group 1: Technology Overview - Tandem OLED technology utilizes a charge generation layer (CGL) to connect multiple RGB emitting units, resulting in improved efficiency and performance compared to standard OLED [1]. - The introduction of tandem OLED screens is projected to increase brightness levels significantly, with potential peak brightness reaching up to 5000 nits in devices like the Honor Magic6 RSR [3]. Group 2: Benefits of Tandem OLED - The technology can reduce power consumption and enhance battery life by achieving the same brightness with lower current, or higher brightness with the same current [4]. - It also extends the lifespan of screens, as each emitting layer experiences only half the electric field strength compared to single-layer OLEDs, leading to reduced thermal effects and slower degradation [4]. Group 3: Market Implications - Honor is set to globally launch the first tandem OLED screen in March 2024, claiming a 50% increase in luminous efficiency [1]. - Apple is reportedly exploring the integration of tandem OLED technology into future iPhone models, with expectations for its debut in the iPhone 20 series by 2028 [4].
