Abstract Cholesteric liquid crystals (CLCs), as photonic materials with unique temperature responsiveness, show great potential in smart optical applications. However, traditional CLC exhibit limitations self‐supporting properties and photoaddressing regulation of thermochromism. Here, dual‐wavelength responsive donor–acceptor Stenhouse adducts (DASAs) are incorporated to construct a sophisticated dual‐mode system for thermochromic polymer dispersed cholesteric (PDCLCs), wherein CLCs droplet form film. This research demonstrates both the reversible photoswitching irreversible Ultraviolet‐induced degradation DASAs can precisely regulate phase PDCLCs while maintaining Bragg reflection throughout visible spectrum. Based on these characteristics, novel temperature‐resolved is designed fabricating anti‐counterfeiting labels, including erasable disposable permanent temperature‐dependent storage indicators. Significantly, synergistic interaction between DASA's absorption PDCLC's achieves distinctive “flickering” effect (dynamic transitions: visible‐invisible‐visible) display. Moreover, enables dual‐photoaddressing encryption secret key within narrow window, creating “read‐and‐destroy” encryption. study presents photoregulation strategy multi‐mode display technology simple preparation convenient readout, paving new ways applications advanced information
