P‐262: <i>Late‐News Poster:</i> A Large‐Size Flexible DDLC Dimming Automobile Sunroof based on PS Matrix Design†

Flexible dye‐doped liquid crystal(DDLC) devices based on PS dot‐matrix design have been realized by combining Roll‐to‐Roll (R2R) processing with ODF (One‐Drop‐Filling) vacuum alignment. Utilizing HTN normallyblack dye liquid crystals, large‐sized flexible dimming films with transmittance range from 1.1% to 24% were successfully produced. By optimizing the PS dot‐matrix density to control the LC margin range and determining the appropriate amount of liquid crystal and lamination pressure, a large‐sized double‐curved automotive sunroof sample was fabricated by using conventional PVB lamination technology.
