What is Smart Glass / Film ?

 

How Does Electrified Switchable / Privacy Smart Glass Work?

This technology will switch the smart glass/film from transparent state to an opaque translucent state with the simple flip of a wall switch, tap of an APP, click of a remote controller, or any smart home control system.  The technology makes available a dynamic space that can be both private and open at the same time.

Uses of switchable privacy glass include:
 
• Residential – bathroom / shower enclosures, partitions
• Commercial – conference rooms, office doors/partitions, reception
• Retail – changing rooms, projection displays
• Healthcare: ICU Doors, Nurseries, ERs, ORs, clinic partitions
• Hospitality – bathroom /shower enclosures, partitions
• Banking – ballistic teller lines, transaction windows, safe deposit rooms
 
 

The Principal

When the power is off the liquid crystal molecules are randomly oriented and will scatter incidental light. This renders the Switchable Privacy Glass panel opaque.
When an electric current is applied, the liquid crystal molecules line up, the incidental light passes through, and the privacy glass becomes clear.
Privacy Glass is a laminated glass. The laminated material within is Liquid Crystal Privacy Film, which responds to an electrical current.
When electricity is applied to the film via the wiring, the liquid crystals align and the glass instantly becomes clear.  When the power is turned off, the liquid crystals return to their normal scattered positions rendering the glass an opaque translucent.

Technology

PDLC (Polymer Dispersed Liquid Crystal) is a medium whose light scattering power is adjustable through applying an electric field. In their natural (uncharged) state, the PDLC droplets randomly align.
PDLC Film consists of a polymer matrix of liquid crystals enclosed by electrically conductive Indium Tin Oxide-coated PET film. The resulting PDLC Film has wiring attached to a conductive copper strip (busbar) along the film’s edge.  In a low voltage platform, this wiring is connected to a step-down transformer through which power is supplied for the “on” (clear) state.  In their natural (uncharged) state, the PDLC droplets randomly align, thus creating the an opaque translucent condition.
Two sheets of glass are laminated over the PDLC film. The components are assembled under high pressure and temperature to form a single unit.
The ordinary refractive index of these liquid crystals does not match that of the polymer, and the incident light is thus scattered, resulting in a translucent state. When an electric field is applied across the material, the PDLC droplets re-orient, and subsequently the extraordinary refractive index of the liquid crystal matches that of the polymer. Therefore, the incident light can pass through, resulting in a transparent state.

  Features and advanatges of adhesive privacy glass film pdlc Also called "  Switchable film  ",  Smart film  ,  Smartglass, Switchable Glass, Intelligent Glass Control, E-Tint  , smart glass, privacy glass, magic glass ... For all these names there is the same product, pdlc glass film , the system in which the laminates lose or gain opacity immediately, at the press of a button. They are known as smart glasses for their ability to offer more benefits to the user than the transparency of ordinary glasses. The pdlc  glass film  is basically a glass connected to the electrical energy can leave films visual opaque or transparent, depending on the time. If it is off, it is opaque, and can even be used as an image projection screen. They can block sunlight and prevent overheating, reducing electricity costs by avoiding the use of air conditioning. In addition, it may also have other more advanced features, such as functioning a...

Switchable PDLC Film Smart Glass Introduction

图片
What’s  switchable glass ? Switchable glass is called smart glass,privacy glass is a new building decoration material that combines the smart film with glass. This laminated smart glass is an innovative opto-electrical laminated glass that composed of two layers of toughened glass on the outer side ,PDLC film in the middle and other composite materials to form a sandwich-like structure. All those materials stick together firmly through special lamination machinery. When powered off, it’s opaque; when power on, it turns transparent instantaneously.  It’s a safety glass that act as smart projection scree too.A variety of glass can be used such as insulating glass, laminated glass, art glass, fireproof glass, etc.It is transparent when power on and opaque when power off,which can be widely used in room partitions,curtain walls,glass doors and windows. 5 reasons to use switchable glass ? Explosion Proof: When our glass is broken by external forces, it will stay ...
