Summary:Optical Encryption Both wavelength‐tunable coloration and light intensity‐tunable photoluminescence are independent and reliably manipulated in a rewritable dual‐responsive encryption display based on block copolymer self‐assembly. The display has the benefit of being a direct and intuitive identification of encrypted information by the human eye, enabling high information security and anti‐counterfeiting.
