Patent ID: 8520287

Claim:
A parallax barrier device, comprising: a first substrate; a first patterned transparent electrode layer, disposed on the first substrate; a first patterned electrochromic material layer, disposed on the first patterned transparent electrode layer, comprising a plurality of electrochromic structures, wherein lengths, widths or diameters of the electrochromic structures are 50 nm to 500 nm, and an included angle of the electrochromic structures and a surface of the first substrate to be deposited is 30° to 89°; a second substrate; a second patterned transparent electrode layer, disposed relative to the first patterned transparent electrode layer on the second substrate; a second patterned electrochromic material layer, disposed relative to the first patterned electrochromic material layer on the second patterned transparent electrode layer; and an electrolyte, disposed between the first patterned electrochromic material layer and the second patterned electrochromic material layer.
