IHS estimates that the wearable display market will grow very quickly in the next few years and revenues will climb from $300 million in 2014 (54 million panels) to $22.7 billion by 2023 (800 million panels).
It's likely that the majority of those wearable devices will adopt flexible OLED displays. IHS explains that wearables are best viewed as functional fashion accessories, and this market is defined by design. This means that wearable products must be adaptable to various forms which requires flexible displays. Wearable displays also require outdoor visibility and low power consumption.
