The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.
With no applied voltage, the liquid crystals are randomly oriented and scatter the light which enters. When an electrical signal is applied, the liquid crystals orient themselves parallel to each other, allowing light through.
You can find PDLC glass in commercial and residential smart windows, consumer electronics and display cases for retail and museums, as well as in healthcare, hospitality and transportation.
Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.

Smart Glass Cost
Smart glass costs $25 to $150 per square foot. Glass with film pre-installed is $50 to $150 per square foot, compared to $25 to $50 per square foot for the film alone. Price depends on the total square footage, with single units running up to $50 per square foot more than you’d pay to install several.
Smart glass makes it easy to change the look of your windows in an instant. You can make them completely opaque for privacy or add tinting to shade a home and cut your energy consumption. There are a few different types with unique benefits, so you’ll need to choose the one that’s right for you. Keep these cost factors in mind as you browse.
Average Smart Glass Price
| Average Cost | $100 Per Square Foot |
| High Cost | $150 Per Square Foot |
| Low Cost | $25 Per Square Foot |
Smart Glass Cost Per Square Foot
Smart glass costs $50 to $150 per square foot. Installers usually set rates by the project, offering a lower price per square foot if you replace several windows. One piece runs $125 to $150 per square foot, compared to $50 to $100 per square foot for 100 or more square feet. The cost to install a window with standard glass is $15 to $30 per square foot.
Smart Glass Pricing by Type
Smart glass prices are $50 to $150 per square foot, depending on the total square footage and type:
PDLC: Privacy, frosted, tinting
SPD: Tinting in an instant
Electrochromic: Gradual tinting to a set level
PDLC
PDLC glass tends to be the most expensive option. It offers privacy at the touch of a button, making it ideal for indoor and outdoor applications. This technology is the only type that turns completely opaque, which means you can use it for bathrooms, showers, private offices and more. You can also turn it into a television projector.
PDLC has crystals that are both liquid and solid, similar to what you’d get in an LCD television or monitor. It has a lot of names, including:
Electric privacy glass
LCD glass
Electric frosted glass
The crystals are inactive when turned off, which makes the glass appear frosted or dark. Once you turn it on, the window is completely clear or dimmable.
SPD
SPD glass is the middle-of-the road cost option, with pricing a little lower than PDLC. This type allows you to select the level of tinting from minimally shading to full darkness, although it can’t provide complete privacy. Its heat-blocking features make it a great choice for exterior windows. You can also use it for any interior room that needs additional darkness in daytime, like a home theater or child’s bedroom.
SPD suspends particles in a liquid. When you turn on the device, it brings those particles in line and allows you to the control the level of tinting. Like PDLC, these windows are dimmable.
Electrochromic
Electrochromic glass is the cheapest option. This type allows you to change the tinting over the course of a few minutes. It uses ions to force particles to the inside or outside of the window, making the material clear or tinted. Those particles stay in position until you use the control to move them again.
Electrochromic glass is similar to photochromic or thermochromic tinting, but it’s important to understand the difference. Photochromic and thermochromic products, like Transitions eyeglass lenses, tint based on light or heat. They don’t require energy to change, but you can’t control them. Electrochromic options use energy comparable to a single LED lightbulb, and make it easy to change whenever you want.
Switchable Glass Prices vs. Smart Window Film
Switchable glass, which may refer to PDLC, SPD or electrochromic products, costs $50 to $150 per square foot and includes all materials and installation. If you want to buy smart film that you can have a pro apply to your existing windows, you’ll pay $25 to $50 per square foot.

How to make smart glass?
Step1. Wash and clean the glass.
Step2. Move the glass to the cleanroom for lamination.
Step3. Check the lower glass and clean possible stains.
Step4. Lay the pre-cut EVA interlayer on the lower glass.
Step5. Lay the PDLC film with busbars onto the EVA interlayer. During the process, the lower protective liner is removed. Then remove the upper protective liner. Note: Do not leave fingerprints or stains on the PDLC film.
Step6. Carefully adjust the position of the PDLC to align with the glass.
Step7. Lay out and align the upper layer of EVA interlayer.
Step8. Check and place the upper glass, carefully adjust the position of the glass to align with the lower glass.
Step9. Check the glass carefully to remove possible dirty spots and stains inside the glass.
Step10. Cut off the EVA interlayer to align with the glass.
Step11. Fix the busbars leads with high temperature tape, and wrap the glass edge with high temperature tape.
Step12. Move the glass to the next operating table.
Step13. Wrap the whole piece of glass in PET film.
Step14. Bond the PET film with silicone sealant strips to form a vacuum bag.
Step15. Set the vacuum port.
Step16. Pump the vacuum bag. Fold and firm the sides of the vacuum bag with high temperature tape.
Step17. During the pumping process, check whether the vacuum bag is leaking. After the pumping is complete, disconnect the pumping pipe.
Step18. Move the glass to the heating platform, connect the glass vacuum port to the vacuum system of the heating oven or autoclave, transfer the glass to the heating oven or autoclave, and heat the glass.
Step19. Heating. parameter settings.
Step20. After heating, remove the glass from the heating oven or autoclave. To pack and store.
