Abstract

The present disclosure discloses a head-wearable displaying and powering system, comprising a head-wearable display device and a portable terminal; the head-wearable display device is provided with one communication interface to connect with the portable terminal; The portable terminal, through the communication interface, transmits audio and video data to the head-wearable display device, exchanges data with the head-wearable display device and provides the working power supply to the head-wearable display device. The head-wearable display device may operate normally after being connected to the portable terminal only via one communication interface, needn'"'"'t occupy too many communication interfaces on the portable terminal and does not limit the application of the portable terminal. As the head-wearable display device acquires the working power supply mainly from the portable terminal, the problem of the overheating of the product caused by the heat generation of the built-in battery is avoided.
