Revolution of Outdoor Digital Displays

May 27, 2016

The future is already here, and it’s bright. Times Square, train terminal displays, and drive-through menus: these are just a few examples of the outdoor digital signage lighting up our world. These devices provide a mix of information and entertainment crucial for a broad range of organizations and applications.

As we move deeper into the twenty-first century, it’s a near certainty that the use of digital signage will continue to increase. Intel reports that digital displays receive nearly 400% more views than static displays. Apocalyptic visions aside, Hollywood is on to something when they portray future cities in movies like Minority Report and iRobot with eye-catching digital displays about the latest products and news.

If there is one feature of these displays that’s anything but futuristic, it’s the cooling systems these signs run on. Commercial vapor-compression refrigeration has been around in some form or another for at least fifty years, and unfortunately many of the long-standing problems with this technology still exist today.

Compression-based cooling systems are bulky, loud, inefficient and full of harmful chemicals.

Phononic is a thermoelectric cooling company that is achieving feats once considered impossible. Their patented solid-state technology is revolutionizing how we cool the world. Everything from computer chips to medical sample preservation relies upon accurate and cost-effective temperature control. Phononic’s revolutionary products are disrupting the outdoor digital signage industry, and smart businesses are taking notice.

The upfront hardware costs for these systems are far more competitive than their compression-based alternatives. Furthermore, Phononic pioneered an active/passive cooling system that relies on electronic control systems and algorithms to only use electricity when necessary. The engineering team at Phononic has also designed their technology to only cool the required components of digital signage, rather than wasting energy chilling the entire structure. These features make solid-state cooling a much more cost-effective choice for long-term operational efficiency. Outdoor digital displays are subject to extreme temperatures. That’s why Phononic’s IP-rated design is built to withstand even the toughest conditions.

As abstract expressionist painter Hans Hoffman once said, “the ability to simplify means to eliminate the unnecessary so that necessary may speak.” This design principle is central to Phononic products. Not only do they reduce the inefficiencies of typical Outdoor Digital Display cooling systems, but they eliminate its distracting byproducts. There is no longer a need for large bulky compressors that shake and rattle. These refrigeration units aren’t suited for thin modern displays, and cause a lot of unnecessary noise that adds environmental noise pollution.

Unfortunately, this isn’t the worst thing traditional compressor technology can add to the environment. These devices require Freon and/or HFC 134a to operate. The EPA is now cracking down on these chemicals because they are extremely harmful to the ozone layer. As an industry, Outdoor Digital Signage will have to move away from using products that are so detrimental to our ecosystem.

The world will continue to develop and use Outdoor Digital Signage. Grand View Research estimates that the market for these products will reach at least $20 billion by 2020. As we do more and more to light up our world, it’s important that we take the proper steps to cool it in a way that is cost-effective, scalable and environmentally safe.

If you fall into a wormhole and find yourself in Chicago in the year 2035, look around. There is sure to be more Outdoor Digital Signage than there is today. And there is a good chance most of it will be chilled with Phononic cooling systems.
