Wearable displays

Definition

Wearable displays are compact electronic devices that can be worn on the body, providing visual information directly to the user. They integrate display technology, such as OLED or quantum dots, into formats like smart glasses or wristbands, allowing users to access data hands-free while on the move. These displays aim to enhance user experience through augmented reality (AR) or real-time notifications, merging digital content with the physical world.
