Spatially Patterned Polymer Dispersed Liquid Crystals for Image‐Integrated Smart Windows

Conventional polymer dispersed liquid crystal (PDLC) films have been successful as electrically-switchable screens for privacy applications. However, spatial patterning of the so to generate a visually appealing design, logo, or image typically requires intricate fabrication processes, such use prefabricated photomasks that do not allow on-demand designs. Herein is reported on and characterization spatially patterned PDLC “pixels” using drop-on-demand inkjet printing, it demonstrated how these materials can be used form new generation smart windows consist embedded images company logos, which made disappear with application voltage. Following refinements material rheology subsequent deposition individual droplets, arrays pixels are printed at resolution 250 per inch an pixel size 130 µm operating electric field strength (E) E = 1.4 V μm−1.
