SPD-Smartglass technology debuts at CES in Cadillac CELESTIQ

In conjunction with General Motors CEO Mary Barra’s keynote address at CES, Cadillac announced the debut of its future flagship ultra-luxury fully electric CELESTIQ sedan, expected to go on sale in 2023

CELESTIQ’s full-glass roof is expected to be one of the first to feature a four-quadrant, suspended-particle-device (SPD) smart glass. With this smart glass, each occupant of the vehicle can set their own level of roof transparency. The driver and front-seat passenger will enjoy a pillar-to-pillar free-form display with active privacy to help mitigate driver distraction while rear-seat passengers have personalized entertainment screens. Console screens between seats in the front and back will separate individualized comfort settings from entertainment displays to minimize distractions.

SPD-Smart light control film, invented and patented by Research Frontiers, is a key component in SPD-SmartGlass products. This film allows users to instantly, precisely and uniformly control the shading of glass or plastic products, either manually or automatically at the touch of a button. Products using Research Frontiers’ smart glass technology are being used in tens of thousands of cars, aircraft, yachts, trains, homes, offices, museums and other buildings.

Joseph M. Harary, President and CEO of Research Frontiers, said, “SPD-SmartGlass will give each occupant of the CELESTIQ the ability to control the heat, light and glare coming into the vehicle, enhancing comfort, security and privacy, while also allowing them to better see information on their entertainment systems and devices. SPD-SmartGlass also can increase the driving range of electric vehicles.”

SPD-SmartGlass light-control technology offers instant and uniform control of the tint of windows that permits them with the touch of a button or automatically using a smartphone, tablet, smart speaker, smart home systems, or other control devices to change tint from dark (blocking over 99.5 percent of light and 95 percent of heat) to clear, or any level in between. This saves energy, creates privacy, and increases comfort and security.

The markets for SPD-Smart film are already well-established. Research Frontiers has licensed over 40 chemical, film, and glass companies which are selling products for the automotive, aircraft, marine, train, museum and consumer electronics industries.

Research Frontiers patented SPD-SmartGlass technology is the same best-selling smart window technology that can be found on various car models from Daimler, McLaren Automotive, and other auto makers.

The MAGIC SKY CONTROL feature, which is now in use on tens of thousands of Mercedes-Benz SLs, SLC/SLKs, Maybach and S-Class models around the world, and more recently on four announced McLaren models, uses patented SPD-SmartGlass technology developed by Research Frontiers to turn the roof transparent by electrically aligning tiny particles in a thin film within the glass. With the touch of a button, drivers and passengers can instantly change the tint of their roof to help keep out harsh sunlight and heat, and create an open-air feeling even when the sunroof is closed.

Glass or plastic, using Research Frontiers’ patented SPD-SmartGlass technology effectively blocks UV and infrared rays in both clear and darkly tinted modes, helping keep the cabin cooler, and protecting passengers and interiors while also enhancing security inside the vehicle. These benefits become even more important when a car uses large surface areas of glass, especially in warm climates.

Some of the other benefits of SPD-SmartGlass include significant heat reduction inside the vehicle (by up to 18ºF/10ºC), UV protection, glare control, reduced noise and reduced fuel consumption. Independent calculations also show that use of SPD-SmartGlass can reduce CO2 emissions by four grams per kilometer, and increase the driving range of electric vehicles by approximately 5.5 percent.

Shortly after its introduction into serial production in the automotive industry, SPD-SmartGlass has become standard equipment on many different aircraft, and is also used in residential and commercial architectural applications, in trains, yachts and other marine vehicles, in display applications, and to protect light-sensitive artwork and documents in major museums around the world.
