PI Alignment Layer (ChLC PI)
Applications
The Cholesteric Liquid Crystal (ChLC) color Electronic Paper Display(EPD) technology features energy-saving and eye-protection characteristics: full reflectivity and bistability. It consumes no power to maintain a static screen—power is only required during screen refreshe — making it highly energy-efficient.
Daxin’s alignment layer utilizes a special diamine monomer that can stabilize both the planar state and the focal conic state, achieving high reflectivity and high contrast.

Features
- High-brightness reflectivity
- Excellent contrast
- Low operating voltage
- Good coatability
