Abstract Blue phase liquid crystal (BPLC) dynamic patterns have attracted wide attention for promising applications in optical information manipulation and visualization sensing, owing to unique 3D chiral helix superstructure adjustable bright/abundant colors response extra fields. Inkjet printing has become an efficient approach achieving programmable BPLC patterns. However, it remains a challenge achieve independent “on/off” control of regional using the same ink due unrevealed temperature‐time‐dependent color change behavior determined by different inks. Herein, comprehensive understanding reflective bandgap shift law versus temperature/time is established investigating diffusion kinetics multiple inks (5CB, 6CB, 8CB) hydrophobically modified blue‐phase polymer templates. The three induce redshift followed blueshift color/reflectance wavelengths, but triggering times differ significantly at temperature, which attributed inks' transition characteristics, fluid properties, interaction with network. Dynamic multi‐color selective region are successfully fabricated based on time‐temperature controlled multi‐ink technique displaying time‐series multi‐level encryption (including “growing apple tree” “nested QR codes”). This study provides important insights into design fabrication advanced devices

Polymer-dispersed liquid crystals (PDLCs) exhibiting electro-optical (E-O) conversion capabilities facilitate modulation across the ultraviolet (UV) to infrared (IR) spectrum. In this study, a bilayer TiN-PVP/PDLC composite film device was prepared by utilizing commercially available polymers and nanoparticles enhance UV IR shielding efficacy. By optimizing ratio of polymer monomers within PDLC layer, superior E-O characteristics were achieved, which further augmented through incorporation TiN-PVP film. The results showed that films had maximum contrast when TiN doping content 1.5 wt %. Notably, demonstrated significant thermal performance under irradiation, with efficiencies exceeding 60% in both off on states, while exhibited commendable values 96.8% 56.9% corresponding states. This facilely synthesized holds promise for passive cooling applications smart window technologies architectural structures.
