Abstract
A rearview mirror, including a first substrate (100), a second substrate (200) cell-assembled to the first substrate (100), and a crystal material (300) filled between the first substrate (100) and the second substrate (200), a plurality of strip electrodes (11) are disposed on a side of the first substrate (100) that faces to the second substrate (200), an interval is formed between two adjacent strip electrodes (110), the strip electrodes (110) are made of a transparent electrode material, a planar electrode (210) capable of at least partially reflecting light is disposed on a side of the second substrate (200) that faces to the first substrate (100). In the present application, the refractive indices of the liquid crystal material (300) in the rearview mirror are changed by changing the voltage signal provided to the rearview mirror, such that an anti-glare operation mode of the rearview mirror is achieved.
