The liquid crystals change their refractive index in relation to the isotropically transparent polymer in which they are immersed, thereby creating multiple step boundaries throughout the PDLC. It is this change in refractive index at each boundary which causes light to change course. Since the PDLC material contains millions of liquid crystals, each with a boundary facing a slightly different way, the light is scattered in many directions. The net effect is to hide whatever is behind the PDLC smart glass.

How to make smart glass?
Step1. Wash and clean the glass.
Step2. Move the glass to the cleanroom for lamination.
Step3. Check the lower glass and clean possible stains.
Step4. Lay the pre-cut EVA interlayer on the lower glass.
Step5. Lay the PDLC film with busbars onto the EVA interlayer. During the process, the lower protective liner is removed. Then remove the upper protective liner. Note: Do not leave fingerprints or stains on the PDLC film.
Step6. Carefully adjust the position of the PDLC to align with the glass.
Step7. Lay out and align the upper layer of EVA interlayer.
Step8. Check and place the upper glass, carefully adjust the position of the glass to align with the lower glass.
Step9. Check the glass carefully to remove possible dirty spots and stains inside the glass.
Step10. Cut off the EVA interlayer to align with the glass.
Step11. Fix the busbars leads with high temperature tape, and wrap the glass edge with high temperature tape.
Step12. Move the glass to the next operating table.
Step13. Wrap the whole piece of glass in PET film.
Step14. Bond the PET film with silicone sealant strips to form a vacuum bag.
Step15. Set the vacuum port.
Step16. Pump the vacuum bag. Fold and firm the sides of the vacuum bag with high temperature tape.
Step17. During the pumping process, check whether the vacuum bag is leaking. After the pumping is complete, disconnect the pumping pipe.
Step18. Move the glass to the heating platform, connect the glass vacuum port to the vacuum system of the heating oven or autoclave, transfer the glass to the heating oven or autoclave, and heat the glass.
Step19. Heating. parameter settings.
Step20. After heating, remove the glass from the heating oven or autoclave. To pack and store.

The polymer allows the liquid crystals to be embedded into a film, which can then be sandwiched between panels of glass or plastic. The polymer has constant optical properties which do not vary across its structure, and hence is considered isotropic. In contrast, the liquid crystal itself is anisotropic, since its optical characteristics are not constant across its structure, but rather can vary under application of an electric field.

With no applied voltage, the liquid crystals are randomly oriented and scatter the light which enters. When an electrical signal is applied, the liquid crystals orient themselves parallel to each other, allowing light through.
