Abstract:
A wearable device, charging device for a wearable device, and charging system. The wearable device (1) comprises a display module (16) and battery module (15), and further comprises: an optical signal detection module (11) disposed at an outer side of the display module (16) and configured to perform detection on ambient light; an optical signal demodulation module (12) configured to demodulate modulated light in the ambient light to obtain demodulated light; and a photoelectric conversion module (13) configured to convert the demodulated light into an electric signal. A battery module (15) can receive an electric signal to be charged according to the electric signal. Without changing the existing use pattern, charging of the wearable device can be completed via modulated light while the wearable device is being used or in a standby mode indoors, thereby improving the charging efficiency of the wearable device and effectively addressing the battery life problem of the battery module of the wearable device.
