The refractive index detector 230 and the data processor (such as a microprocessor or computer and other equipment with computing functions) obtain the changes of the glass screen 30, such as whether there is water mist on the surface of the glass screen 30 and the area where the water mist occurs. Wait. Specifically, when water mist appears and water droplets adhere to the glass screen 30, the reflectivity of the glass screen 30 will undergo a sudden change, and the reflectance detector 230 can record the position of the sudden change, and by scanning the entire surface of the glass screen 30, The reflectance of each position on the surface of the glass screen 30 is obtained, the greater the reflectance, the more severe the water mist. Then, the reflectance detector 230 can send the measured reflectance value to the data processor, and the data processor can judge and calculate the area where water mist occurs through a preset reflectance threshold α, for example, by calculating the reflectance ≥ α to obtain the area where water mist occurs, and then calculate the area ratio of water mist according to the total area of the glass screen 30, or calculate the number of detection points with reflectivity ≥ α and the ratio of all detection points, and then Indirectly obtain the area ratio of water mist.
