Filmbase Limited Edition Smart Film

Technical Principles

• PDLC film in the absence of an electric field,the electronically controlled smart film is in an opaque state.When an alternating current is applied, the liquid crystal molecules are arranged in an orderly manner, at which point the electrically controlled dimming film changes from an opaque state (OFF) to a transparent state (ON).
• PNLC film different from normal PDLC smart film,the working principle of PNLC film is opaque-power on,clear power off. The electric field enables a rapid transition from the ON state to the OFF state and from the OFF state to the ON state.Smart film is usually applied to the surface of the glass or laminated between the glass layers, making the otherwise transparent glass, more possible.
• Polymer Dispersed Liquid Crystal Smart films is commented the most advanced curtain today and future,designed new or retrofit an existing space for an instant upgrade，instantly switching from opaque to transparent for dynamic light control with a HD real projection function ,widely used in interior and architectural design, commercial center ,rail transportation, and even avant-garde industrial products.
