DYNAMIC GLAZING

This presentation will give an overview of dynamic glazing technologies based on liquid crystals, suspended particles and electrochromics that are being adopted in architectural and automotive applications. Polymer dispersed liquid crystal (PDLC) based windows switch very fast within few hundred milliseconds, have high contrast but suffer from high haze, high voltage, high power and no heat blocking capability making them unsuitable for external architectural window applications. PDLC technology is primarily used for privacy windows. Suspended particle (SPD)technology switches fast in a few seconds, has good contrast but requires high voltage and high power with some heat blocking capability. SPD has made significant inroads into automotive market (especially dynamic sunroof) but has limited success in architectural markets. Electrochromic technology (EC) switches at low voltage, consumes very little power, has low haze and good contrast but switches slowly making them unsuitable for automotive and wearable applications. EC windows have excellent heat blocking capability making them preferable for architectural applications especially for outside windows. High cost and slow switching speeds are limiting adoption rate of EC technology. Argil is developing next generation fast switching low cost electrochromic film that can be laminated between glass for use in automotive, architectural and wearable applications.
