LG Display extends tandem OLED to phones and wearables for AI power demands

LG Display announced plans to expand tandem OLED technology beyond its current applications in televisions, monitors, and automotive displays into the smartphone and wearable markets. The expansion is motivated by the growing integration of on-device artificial intelligence in mobile devices. As AI models run directly on smartphones and wearables—rather than relying solely on cloud processing—power consumption increases significantly. Display panels are typically the largest power drain in a mobile device, so reducing display power consumption becomes critical to maintaining usable battery life while supporting AI features. Tandem OLED, which the company has already proven in larger screens, is positioned as a power-efficiency solution for these mobile form factors. The company's move signals that power-efficient displays will be a key differentiator in the next generation of AI-enabled mobile devices.

LG Display's move to bring tandem OLED into smartphones and wearables reflects a broader shift in mobile hardware design. As on-device AI features become more common—allowing phones and wearables to run inference tasks locally without relying solely on cloud servers—the power demands on a device's battery increase. Display technology is often the single largest power consumer in a mobile device, so manufacturers seeking to balance AI capability with battery life have strong incentive to adopt more power-efficient screen technology. LG Display, which has already validated tandem OLED in larger form factors such as TVs, monitors, and automotive displays, is positioned to transfer that expertise to smaller, mobile screens.
