DIMMABLE SUNVISOR

摘要

A dimmable visor is disclosed. In one embodiment, the visor includes a first clear sheet having a first surface and an electro-opaque sheet having a first surface and a second surface and having adjustably variable transparency. The first surface of the electro-opaque sheet is in contact with the first surface of the first clear sheet. The visor also includes a pair of transparent electrodes disposed on two opposite edges of the electro-opaque sheet, each of the transparent electrodes having an area smaller than the electro-opaque sheet. The visor also includes a second clear sheet having a first surface in contact with the second surface of the electro-opaque sheet. The visor also includes a suspension hinge attached to one edge of the first clear sheet and is configured to rotate about the suspension hinge. The electro-opaque sheet changes its transparency in response to electrical energy being applied to the electro-opaque sheet.
