@howitworkssss: China’s smart glass technology allows windows to instantly switch between opaque and clear states using electrically controlled materials. When powered on, the glass becomes transparent, allowing light and visibility to pass through. When the current is turned off or adjusted, the glass turns frosted or opaque, providing instant privacy and glare control. This is achieved using special liquid crystal or electrochromic layers embedded within the glass. The innovation is widely used in modern architecture, offices, hospitals, and high-speed trains to improve comfort, energy efficiency, and privacy on demand.
