FAQ

• Q91:

  Which Film Uses Power When the Glass Is Clear?

  

  A:

  PDLC needs power to remain clear; PNLC does not. If the glass will stay clear for most of the day, PNLC may reduce operating time under power. Actual energy use depends on the product and how long each state is used.

  
  

• Q92:

  Which Film Is Better for Privacy During a Power Outage?

  

  A:

  PDLC is the better choice if the glass must become frosted when power is unavailable. PNLC needs power to maintain its frosted privacy state.

  
  

• Q93:

  Which Film Stays Clear During a Power Outage?

  

  A:

  PNLC stays clear when power is lost. PDLC returns to its frosted state. Consider the required appearance during a power outage when choosing between them.

  
  

• Q94:

  What Does PNLC Stand For?

  

  A:

  PNLC stands for Polymer Network Liquid Crystal. It is often called reverse mode smart film because its clear and frosted states are opposite to those of standard PDLC film.

  
  

• Q95:

  What Is the Main Difference Between PNLC and PDLC Smart Film?

  

  A:

  The main difference is what happens when power is off. PDLC is frosted without power and clear when powered on. PNLC works in reverse: it is clear without power and frosted when powered on.

  
  

• Q96:

  What Should I Do Before Installing Display Cloaking Film?

  

  A:

  Test a sample against the actual project screen first. Check the cloaking effect from the required viewing side, determine the effective film direction, and mark that direction before cutting or installation. Only proceed once the screen compatibility and orientation are confirmed.

• Q97:

  Is Display Cloaking Film the Same as PDLC Smart Film?

  

  A:

  No. PDLC electrically switches the whole glass panel between clear and frosted. Display cloaking film stays transparent, requires no power and targets compatible screen content.

• Q98:

  Can People Inside the Room Still See the Screen?

  

  A:

  Yes. Display cloaking film is applied to the glass, so it does not affect how people inside the room view the screen directly. It obscures compatible screen content only for people outside who view the screen through the film.

• Q99:

  Why Does Film Direction Matter?

  

  A:

  Display cloaking film is directional. The orientation that obscures one screen may not work for another, so the effective direction must be confirmed using the project’s actual display before the film is cut and installed.

• Q100:

  Will It Hide Laptop, Tablet and Phone Screens?

  

  A:

  That depends on the individual display. Do not assume a device is compatible based only on its size or product category. Test each screen whose content needs to be concealed.
