In response to the COVID-19 epidemic, various countries have issued a series of bans, city closures and traffic restrictions, driving the demand for housing, working at home, online shopping, and home entertainment. This in turn has driven the demand for 3C products such as information and communications products. Among these, display panels have shown one of the greatest increases in demand, and the global display screen equipment market grew by 19% in 2020, reaching USD 13.52 billion.
