Glare refers to strong reflected light that causes visual impairment. The specular reflection on the LCD screen surface is the main cause of glare. With the development of information technology and the popularization of personal computers, tablets, mobile phones and other devices, the frequency of screen use has greatly increased. Users' visual health is easily damaged by glare for a long time. In some special circumstances, such as when a fighter jet is flying at high altitude and the intensity of sunlight is very high, if a strong glare effect is formed on the surface of the airborne LCD display, the pilot may be temporarily blinded. Therefore, the research on anti-glare technology is of extremely important significance to many fields.
