From "cyber fans" to naked-eye 3D — how screens provide psychological cooling for cities
When the giant animated fan on an outdoor screen in Changsha's Wuyi Square kept spinning tirelessly, passersby stopped to take photos and smile. At the same time, in Zhengzhou's "Only Henan·Drama Fantasy City," the electronic screen looped a virtual air-conditioning cooling animation, jokingly called "cyber air-con" by netizens. These creative ideas are spreading across cities nationwide. An outdoor screen is no longer just a commercial advertising carrier but has quietly become an "emotional pressure valve" in urban public spaces — using humor to ease the summer heat and providing a kind of "psychological cooling" through creativity.
From "Quenching Thirst by Thinking of Plums" to "Cooling with a Painted Fan"
The key to the viral success of "cyber cooling" lies in its precise capture of the shared emotions of citizens during heatwaves. The Changsha creative team replaced commercial ads on the mall's exterior screen with a fan animation to offer visitors psychological relief. The Zhengzhou scenic area staff also said the air-con imagery was meant to ease visitors' irritation while waiting in line. Netizens joked: "Between turning on the AC and the fan, they chose to joke around." Physical perception and emotional experience diverged — physical cooling failed, but psychological comfort worked. This seemingly absurd gesture turned "passive heat avoidance" into "active social participation."
Under the Scorching Heat, How Can Outdoor LED Displays Stay Color-Fast for 5 Years?
While city screens busy themselves with "cyber cooling" for pedestrians, the screens themselves endure real heat stress. Surface temperatures in the Middle East frequently exceed 60°C, with intense UV radiation constantly eroding LED lamp beads and encapsulating materials. In many parts of China, summer heat pushes internal screen temperatures beyond 70°C. Ordinary displays often suffer rapid brightness decay, encapsulant yellowing, and module cracking under such conditions.
Kingaurora has specialized in outdoor LED displays for over 17 years. Its independently developed DIP570 lamp bead technology is built for extreme environments:
Ultra-High Brightness
8000-10000nit, clear and vivid even under direct midday sun
UV Resistance
Full epoxy encapsulation structure resists UV degradation
Low Lumen Depreciation
Less than 15% brightness decay in 5 years, 8-10 years stable operation
Wide Temperature Range
-40°C to 60°C, reliable operation in all climates
While city screens use creativity to provide psychological cooling, Kingaurora uses reliable technology to keep every screen running smoothly. True heat resistance is measured by whether a screen stays color-fast for 5 years and performs as new for 10.
Where Is the Next Growth Opportunity for Outdoor Screens?
From Changsha's fan animation to Zhengzhou's "cyber air-con," outdoor screens have pushed creativity to new heights this summer. The next wave may well be naked-eye 3D screens — with no need for 3D glasses, the lifelike stereoscopic effect of images "jumping out of the screen" has made them popular city landmarks. From the climbing 3D panda in Chengdu to similar projects across the country, this format is redefining the visual imagination of urban public spaces. Operators note that core business districts in China's first- and second-tier cities all need digital media to attract foot traffic — naked-eye 3D screens are not just ad space, but "city media."
Conclusion
From the playful cooling of "cyber fans" to the visual impact of naked-eye 3D, outdoor screens are redefining the boundaries of urban public space. Behind every brilliant visual creation lies a high-quality screen that can withstand heat and stand the test of time.
Kingaurora — with 17 years of outdoor display expertise, turning every screen into a landmark's "traffic magnet."
