Abstract
This application relates to the field of electronic devices, and discloses a wearable device. The wearable device includes a housing, a display, and a battery. The display and the housing are fastened and enclose accommodation space. The battery is accommodated in the accommodation space. The display includes a display panel, a transparent substrate, a first solar panel, and a first cover plate. The transparent substrate is disposed on a side that is of the display panel and that faces away from the accommodation space. The first solar panel is disposed in a first region on a first surface that is of the transparent substrate and that faces away from the accommodation space, and the first solar panel is electrically connected to the battery. The first cover plate is disposed on a side that is of the first solar panel and that faces away from the accommodation space, and an optically clear adhesive is filled between the first cover plate and the transparent substrate. In this application, the first solar panel is integrated into the display, so that high-level waterproof and dustproof effect can be achieved on the first solar panel, and solar energy reception efficiency of the first solar panel can be further improved. In this way, the wearable device can implement highly efficient charging by using the first solar panel.
