Abstract: A rear-view mirror includes a body, wherein the body includes a first polarizer, a dimming layer, a transflective polarizer, and a display component which are sequentially laminated. The dimming layer is configured to adjust a polarization direction of light passing through the dimming layer. By adjusting the polarization direction of the light passing through the dimming layer via the dimming layer, the reflectivity and transmittance of the transflective polarizer to the light can be changed, such that both an anti-glare function and a display function of the rear-view mirror can be achieved.

Abstract: An array substrate and a wearable device are provided. The array substrate includes a base substrate. A first surface of the base substrate is provided with a plurality of first signal lines having a concentric arc shape and a plurality of second signal lines linearly arranged along a radial direction of the first signal lines. A first driving circuit connected to the respective first signal lines is provided on the first surface or a second surface of the base substrate and a second driving circuit connected to the respective second signal lines is provided on the first surface or a second surface of the base substrate. In the array substrate, since the first driving circuit and the second driving circuit are both positioned within a display region, the screen proportion of the display region is improved, thereby achieving a narrow bezel design or even bezel-free design for the wearable device.
