Abstract
The present invention provides a rearview mirror comprising a panel and a control circuit, a first substrate in the panel is provided with a planar transparent electrode layer, a second substrate is provided with a transparent hydrophobic material layer and multiple block electrodes, a side of the transparent hydrophobic material layer facing the first substrate is provided with multiple cells, lightproof electro-wetting ink is provided within each cell, the block electrodes are provided on a side of the transparent hydrophobic material layer away from the first substrate and can at least reflect part of light entering the rearview mirror from first substrate side, the control circuit is configured to control area of each cell covered by the electro-wetting ink in the cell by controlling a change in intensity of the electric field between the planar transparent electrode layer and the block electrodes.
