“Liquid crystal displays are widely used in various fields, and their high-precision control characteristics are also demonstrated in non display fields. To meet the demand for high-speed regulation, overvoltage drive technology has attracted attention. Researchers have optimized the response performance of liquid crystal display devices by applying overvoltage driving technology, which has been applied in non display fields such as spatial light modulators and liquid crystal lenses. Despite facing technological challenges, overvoltage driving technology has opened up new directions for the development of liquid crystal displays and is expected to achieve more breakthroughs in the future.”
