AI Technical Summary

Technical Problem

While existing multi-layer glass panels meet sensor needs, it is difficult to maintain good optical characteristics and sensor compatibility, especially when solar absorbent materials become darker over time, resulting in reduced light transmission.

Method used

A multi-layer panel structure is employed, including different types of polymer sandwich to provide specific optical transparency and characteristics in different sensor areas. By using different materials in the interlayer or applying coatings and patterns on the glass substrate, the light transmittance is adjusted to suit the needs of different sensors.

Benefits of technology

The multi-layer glass panel is achieved while maintaining good optical characteristics, excellent sensor compatibility, ensuring that the sensor can operate normally and the transmittance remains stable.
