All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic diagram of an application of a wearable device according to an embodiment of the present application, and fig. 2 is a schematic diagram of a composition structure of a wearable device according to an embodiment of the present application, as shown in fig. 1 and fig. 2, an embodiment of the present application provides a wearable device, which may be applied to glasses, and includes: mounting bracket 110, lens 120, photosensor 130, first switch 140, and filter controller 150. The lens 120 is mounted on the mounting frame 110, and the lens 120 includes a Liquid Crystal Display (LCD) panel 121 with backlight removed; the photosensitive sensor 130 is arranged on the light receiving surface of the wearable device and used for detecting ambient light; the first switch 140 is used for switching the full spectrum filtering function or the blue spectrum filtering function of the wearable device; the filter controller 150 is connected to the liquid crystal panel 121, the photosensor 130, and the first switch 140; the filtering controller 150 controls the liquid crystal panel 121 to attenuate the ambient light passing through the liquid crystal panel 121 according to the light intensity of the ambient light when the wearable device is in the full-spectrum filtering function; the filter controller 150 controls the liquid crystal panel 121 to attenuate the blue light transmitted through the liquid crystal panel 121 according to the blue light in the ambient light when the wearable device is in the blue spectrum filtering function.
In the embodiment of the present application, the liquid crystal panel 121 may be an existing liquid crystal panel, for example: twisted Nematic (TN), Super Twisted Nematic (STN), Double layer Super Twisted Nematic (DSTN), or Thin Film Transistor (TFT) liquid crystal panels, etc.; the liquid crystal panel 121 may also be a specially manufactured liquid crystal panel without backlight; the embodiment of the present application does not limit the type of the liquid crystal panel.
