FAQ

• Q1:

  What is PNLC Smart Film and how does it work?

  

  A:

  PNLC, also referred to as reverse PDLC film. Unlike standard PDLC film, PNLC remains transparent in the power-off state and switches to frosted opaque when powered on. Our PNLC film delivers excellent UV resistance, making it suitable for sunlit windows and sun-exposed glass applications.

• Q2:

  How transparent is PDLC Smart Film when switched on?

  

  A:

  The transparency of PDLC Smart Film depends on the film structure, materials and manufacturing technology. High-quality optical-grade PDLC can provide high visible light transmission and low haze when switched on. InnoGlass offers High Definition PDLC Smart Film designed to provide enhanced transparency and visual clarity for applications where optical performance is important.

• Q3:

  Is PDLC Smart Film transparent when powered on or off?

  

  A:

  For conventional PDLC Smart Film, the film is transparent when powered on and becomes translucent or opaque when powered off. This allows users to switch between an open, transparent view and a private state instantly.

• Q4:

  How long does PDLC Smart Film last?

  

  A:

  The service life of PDLC Smart Film depends on film construction, electrical control system, installation quality, operating conditions and environmental exposure. Our PDLC smart film has passed relevant tests with a rated lifespan of 100,000 hours. High-quality PDLC film with proper installation and appropriate operating conditions can maintain stable long-term performance. Manufacturers should provide durability and accelerated aging test data for specific products.

• Q5:

  How is self-adhesive PDLC Smart Film installed?

  

  A:

  Dry application: Ensure the glass surface is fully cleaned first. Align and position the self-adhesive film onto the glass directly. Slowly peel off the release liner while pressing the film onto the glass. Carefully squeeze out trapped air bubbles with a squeegee. Let the film settle fully before edge sealing and final testing. Correct installation is critical for a smooth, even finish.

• Q6:

  How much power does PDLC Smart Film consume?

  

  A:

  PDLC Smart Film consumes electricity mainly when it is in the transparent state. Power consumption depends on the film size, operating voltage and product design,normally about 4W/sqm. Because the film is generally powered only when transparency is required, its overall energy consumption can be relatively low compared with continuously powered glass technologies.

• Q7:

  Can PDLC Smart Film be installed on existing glass?

  

  A:

  Yes. Self-adhesive PDLC Smart Film is specifically designed for installation on existing flat glass surfaces. It is commonly used for office partitions, meeting rooms, doors, windows and other renovation applications without replacing the original glass.

• Q8:

  How Do I Choose Between DLC, PDLC, PNLC and EP (SPD)?

  

  A:

  Choose PDLC for white frosted privacy when power is off, PNLC for a clear off-state, DLC for dark opaque privacy when power is off, or EP (SPD) when adjustable visible light transmission is the main requirement.

• Q9:

  Can PNLC and PDLC Both Be Used for Projection?

  

  A:

  Their frosted states may be used as projection surfaces, subject to the film specification and room lighting. The key planning difference is that PNLC must be powered for its frosted state, while PDLC is frosted without power.

  
  

• Q10:

  Are PNLC and PDLC Suitable for Solar Control?

  

  A:

  Both primarily switch between clear and frosted views. A frosted appearance does not by itself indicate strong solar heat reduction. If controlling sunlight and heat is the main goal, compare measured performance for the complete glazing system.

  
  

• Q11:

  Is smart glass suitable for hospitals and healthcare facilities?

  

  A:

  es. PDLC and PNLC smart glass can provide instant privacy for patient rooms, ICU areas, consultation rooms and medical partitions. The smooth glass surface is also easier to clean and maintain than many traditional curtains or blinds while allowing natural daylight into the space.
