The switchable smart glass market encompasses the production and distribution of electrically active glazing materials that dynamically control light transmission, heat transfer, and privacy through applied voltage or environmental stimuli. Developed initially at Kent State University in the late 1980s, smart glass products consist of two glass layers sandwiching liquid crystal film and PVB interlayers processed through high-temperature, high-pressure lamination.
The technology enables instantaneous switching between transparent and opaque states through electrical current control, combining safety glass impact resistance with 75% light transmission and 3cm privacy distance, supporting projection imaging functionality with average power consumption of approximately 5 watts per square meter. Products employ PDLC technology where liquid crystal molecules arrange randomly without power for translucent appearance, then align orderly when energized to restore transparency.
