EPC（Electric Polarized Crystal）Glass

EPC Glass refers to a type of glass incorporating Electric Polarized Crystal technology, which likely enables light modulation or optical property adjustments through electrical control. Its core mechanism may involve aligning polarized crystals via electric signals to regulate transparency, glare, or light transmission.

Potential applications include smart windows, automotive sunroofs, or display panels, where dynamic light control and energy efficiency are prioritized. The technology could enhance user comfort by reducing glare and optimizing natural lighting.

As demand for smart building materials and energy-efficient solutions grows, EPC Glass could cater to sectors like construction, automotive, and consumer electronics. Its integration with IoT systems will automated light management.
