MULTI-PURPOSE ELECTRICAL WINDOW AND METHODS THEREOF

摘要

These teachings disclose a multi-purpose electric window that comprises a printed transparent sheet and a reflective layer laminated onto an electric light-switching device and a power source. The electric light-switching device is made of electrically actuated polymer dispersed liquid crystal or suspended polarized particles laminated between two transparent electrodes. There are surface lens structures at one side or both sides of the transparent sheet. Images are printed unto the surface lens structures. The lens structures are selected from prism, half spherical, half cylindrical, pyramidal, Fresnel structure or a combination of the above. The transparent sheet is laminated on the side with reflective layer or the other side of the electric light-switching device without reflective layer. Light emitting diodes can be placed at the sides or under the transparent sheet.
