Basic Film Structure & Operating Principle
Standard Type / Thermal Barrier Type
Power OFF (Opaque State)
When no voltage is applied, the liquid crystal molecules are randomly oriented. Incoming light is scattered by the liquid crystal layer, creating a translucent (privacy) state. Some light transmission remains, but direct visibility is blocked.
Power ON (Transparent State)
When AC voltage is applied, the liquid crystal molecules align in a uniform direction. As a result, incident light passes through the layer with minimal scattering, enabling transparency. The Thermal Barrier Type integrates infrared-reflective functionality while maintaining the same switching principle.
Reverse Type
Power OFF (Transparent State)
Through an internal structure, the liquid crystal alignment is stabilized without applied voltage, maintaining transparency in the power-off condition.
Power ON (Opaque State)
When AC voltage is applied, the molecular alignment changes, generating light scattering and producing the opaque state.
This reverse switching behavior differs fundamentally from conventional PDLC operation.
Dye Doped PNLC (Color Type)
Power OFF (Opaque / Colored State)
The liquid crystal layer includes dyes that operate together with the liquid crystals during switching.
Power ON (Transparent State)
When AC voltage is applied, the liquid crystals align and reduce light scattering, while the dye response is simultaneously controlled, enabling high contrast between transparent and shaded states. The Black Type provides enhanced shading performance while maintaining clarity in the transparent state.
Reverse Dye-Doped PNLC (Reverse Color Type)
Power OFF (Transparent State)
Through the proprietary reverse-mode PNLC structure, the liquid crystal alignment is stabilized without applied voltage, maintaining transparency in the power-off condition. Integrated dyes remain inactive in this state, allowing clear visibility.
Power ON (Opaque / Colored State)
When AC voltage is applied, the molecular alignment changes, generating light scattering and producing the opaque state.
This reverse switching behavior differs fundamentally from conventional PDLC operation.
