PDCLC (Polymer Dispersed Colorant Liquid Crystal) is a new type of electronically controlled light-regulating product. When in the off-state, it appears as a neutral gray-black, providing functions such as light blocking, shading, and privacy protection. In the on-state, it becomes transparent with clear visibility and a wide viewing angle. It can be applied to smart automotive glass, building curtain wall, consumer electronics, and other fields.
