What Is Smart Glass Projection?

There are numerous different types of smart glass projection out there, although trying to work out the exact differences can be confusing. The relatively new technology is exciting and has many different applications but how do you know what kind of smart glass projection is right for you?


Product types

There is a plethora of different options on the market so you’ve probably come across terms like electrochromic, thermochromic and photochromic glass. In each category there are also several different ‘technical’ options like PDLC – different manufacturers will use different technology types. In electrochromic smart glass projection, morphology is controlled by the conversion between liquid crystal molecules. Another coating type is ITO which basically uses a specialty conductive layer to transition and throw smart glass projection. ITO coatings can be dimmed or changed by differences in voltage and current conversion.

ITO coatings on PET film are usually attached to the smart glass projection surface and has insulation properties. The colour change on the surface comes from changes to the voltage and current.


Product applications

There are many applications for different types of smart glass projection technology. New ways to use it are being thought of all the time but you’ll often see the technology in conference rooms where it can be used for presentations, in office spaces where it can be used for privacy, in shower rooms, in theatres and on shop fronts and in commercial buildings. In many cases when instantaneous switching between the opaque and transparent glass is needed, PDLC products are the optimal solution. Other types of electrochromic products tend to take longer to make the transition which is not ideal for these applications. PDLC can usually be purchase as an adhesive coating or as laminated glass. When the existing glass is modified costs and installation can be very low. PDLC is also an attractive choice for many are it has a smart glass projection imaging capability. ON PDLC it’s possible to project clear imagery which is popular for show windows and on fil stages and in theatres. PDLC is a relatively cost-effective option and the technology is quite well developed especially compared to other types of smart glass projection.


Popular manufacturers of the product include companies like Polytronix and Innoglass. You might also come across names like Dreamglass and DMD. All of these manufacturers have different strengths and weaknesses with some focusing on different voltages and others offering a variety of voltage options. Most of them are positively regarded for their customer service and the availability of low voltage compatible products, high transparency products and low haze solutions.

Certain types of electrochromic, thermochromic and photochromic products are more suitable for the outdoors than others. These products also have many applications are now being seen regularly on commercial buildings. They have a striking, seamless look and will no doubt be used in new and interesting ways going forward into the future. Many people are now opting to build it into new buildings and it becomes a regular fixture in offices, hospitals and homes around the world.


If you’re planning to use it in your space it is best to speak to the manufacturer and a professional installer to ensure that you find the right product for your particular needs and application. If you’re not sure what you need, start by doing some research online and check out stockists and installers in your local areas. It’s a good idea to check out reviews to ensure that any technology you choose to invest in is well-regarded by customers that use it for both residential and commercial applications.
