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, andfilter controller 150. Thelens 120 is mounted on themounting frame 110, and thelens 120 includes a Liquid Crystal Display (LCD)panel 121 with backlight removed; thephotosensitive sensor 130 is arranged on the light receiving surface of the wearable device and used for detecting ambient light; thefirst switch 140 is used for switching the full spectrum filtering function or the blue spectrum filtering function of the wearable device; thefilter controller 150 is connected to theliquid crystal panel 121, thephotosensor 130, and thefirst switch 140; thefiltering controller 150 controls theliquid crystal panel 121 to attenuate the ambient light passing through theliquid crystal panel 121 according to the light intensity of the ambient light when the wearable device is in the full-spectrum filtering function; thefilter controller 150 controls theliquid crystal panel 121 to attenuate the blue light transmitted through theliquid 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, theliquid 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.; theliquid 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. Alternatively, theliquid crystal panel 121 may be separately manufactured into thelens 120 for use; alternatively, theliquid crystal panel 121 may be superimposed on various existing lenses and used as thelens 120 together with the existing lenses, for example: the flexible LCD can be superposed on the lens of the plano-optic glasses, or the flexible LCD can be superposed on the lens of the myopia glasses, or the flexible LCD can be superposed on the lens of the presbyopic glasses, etc.; the present embodiment does not limit the arrangement manner of theliquid crystal panel 121 in thelens 120.

Alternatively, when theupper polarizer 310 and thelower polarizer 380 are placed perpendicular to the polarization direction, the light transmitted through theupper polarizer 310 cannot pass through thelower polarizer 380 in a state where theliquid crystal 340 is not energized; after theliquid crystal 340 is powered on, the light transmitted through theupper polarizer 310 is rotated by a certain angle when passing through theliquid crystal 340 due to the optical rotation effect of theliquid crystal 340, so as to generate a certain component in the polarization direction of thelower polarizer 380, and then pass through thelower polarizer 380, wherein the larger the component generated in the polarization direction of thelower polarizer 380, the more the light passes through thelower polarizer 380.
