Patent number: 8871327Abstract: A camouflage structure, capable of altering its appearance, comprises a camouflage graphic layer and a color-changing layer disposed on the camouflage graphic layer. Originally, the camouflage structure presents a first color state. After the color-changing layer changes the color by driving methods, the camouflage structure presents a second color state. For example, a transparent or semi-transparent color-changing layer able to reflect or emitting red light could be disposed on the woodland camouflage graphic layer, which allows for the overall appearance to change from the greenish woodland camouflage to the brownish desert camouflage. Alternatively, the camouflage structure could comprise a greenish camouflage graphic layer made of material with red-shift characteristics, which means the greenish camouflage graphic layer consists of different colors of chromic materials with reversible red-shift characteristics.Type: GrantFiled: March 22, 2011Date of Patent: October 28, 2014Assignee: Industrial Technology Research InstituteInventor: Chen-Chu Tsai
