New Trend of Transparent LED Screen for The Debut of The World’s First 3D Dome

in /by

On January 24, 2022, the crystal ball of Metro City, Xujiahui, Shanghai has launched a renewal and upgrade that 3,888 high-definition 4K screens replaced the original light band particles, becoming the world’s first naked eye 3D dome. 3D dome as a landmark in Xujiahui Shanghai, adds dynamism for the night landscape of the downtown with a fantastic 3D image and helps boost the tourism consumption of the business district.

The crystal ball of Metro City started out as a composition of LED lighting particles and was later upgraded several times to become the UHD 4K screen it is today. Since the crystal ball of Metro City is spherical, different from the traditional flat and large folding corner screens, it is a tough and challenging job no matter the design and installation of LED display module or 3D visual presentation. To present the naked eye 3D effect perfectly, 3,888 pieces of glass facets form the main frame of the whole 3D dome to create a subtle refraction halo for the dome. In addition, a high-definition 4K screen was installed behind each cutout for high-definition and high-contrast images. What is certain is that the upgraded 3D dome is 20 times sharper and has more features than traditional screens could ever hope to offer. By importing pre-made UHD 3D video modeling, 3D dome of Metro City can present a holographic 3D image with a technological and futuristic feel.

The 3D visual presentation on the dome is the first of its kind in the world, which fully demonstrates China’s outstanding achievement in LED display technology. LED displays were initially in the public eye in the form of a flat screen with their initial function of being placed outside buildings and shopping centers for merchants to advertise. But with the development of the Internet and the progress of the times, this functional attribute is being weakened continuously. On the basis of technology-based genes, LED screens have been derived from a variety of screen types, such as narrow pixel pitch LED screens, flexible LED screens and transparent LED screens, and so on, which have expanded more application possibilities for users. For example, flexible LED screens can provide merchants with different shapes of screen displays due to their flexibility in shape and size; while transparent LED screens are an innovative LED display solution that can achieve 55-90% transparent display through hollow design structure and side light-emitting technology without damaging and obscuring the original structural features and aesthetics of the building.

Under the trend of the rise of new media forces in the market, the combination of outdoor advertising industry with LED display screen as the main medium and urban landmark aesthetics has provided multi-dimensional new ideas and enthusiastic practices for the diversified market demands of brand customers. The new generation of transparent LED display technology, as the new direction of LED display, will be the biggest driving force of this innovative development due to its easy installation and maintenance, and suitable for both flat and curved surfaces. According to forecast data, the market value of transparent LED screens is about $87.2 billion by 2025. There is no doubt that transparent LED screens will become increasingly popular worldwide, and this growth will undoubtedly lead to unprecedented opportunities.

The successful upgrade of Metro City’s 3D LED ball is the result of the combined effect of flexible LED screens and transparent LED screens. The transparent LED screen with 55%-90% transparency can be easily installed behind glass windows and can even replace glass to achieve a wonderful and stunning visual display. With the unique feature of transparent LED screen, 3D LED ball is being explored in an innovative way to create a new “Metro Universe” by combining various IPs loved by young people, thus enabling its surrounding merchants to achieve rapid growth of economic benefits and brand promotion. Moreover, with the integration of 5G+8K+AI technology, 3D dome, as the future trend of transparent LED screen, will also be applied to virtual interactive experience, i.e. merchants can replicate consumers’ characters to the dome surface in real time for interaction with the help of holographic projection and portrait capture technology. At the same time more topical interactive game experience will also be realized online and offline linkage through smart phones.

The truth is also moving in its established direction. LED displays are moving towards high definition, intelligence and diversity and will no longer be limited to traditional advertising displays. With HD display technology, 5G communication technology, AI technology, 3D display technology, etc., transparent LED displays will be applied to interactive experiences that are closer to the consumer group so that potential customers can interact with the brand to learn more.

If you are stuck in an innovation bottleneck and have no ideas on how to get closer to your potential customers, then you may want to try using transparent LED displays as an innovative solution to break the tradition and achieve absolutely superior business growth and brand promotion by increasing user interaction with the screen. With the opening ceremony of the 2022 Winter Olympics in Beijing, China presented a feast of technology and aesthetics to the world with the world’s largest 8K LED display. It has to be said that China’s LED display technology has taken a new step forward and it also fully demonstrates China’s superior LED display technology and the strength of Chinese LED screen manufacturers. RIGARD is one of the leading LED screen manufacturers in China, dedicated to breakthroughs in innovative LED display technology, offering a lot of types of LED screens, including transparent LED screens, flexible LED screens, 3D LED screens, 4K screens and 8K screens for indoor and outdoor applications.

If you are considering investing in transparent LED screens, RIGARD is a great choice for you. This is not only because RIGARD is committed to providing customized LED module designs to suit your brand style according to your individual needs, but also offers transparent LED screens with ultra-high density pixel pitch to ensure your images are more vivid and beautiful. In addition, the transparent LED screen of RIGARD has a reputation for 55% to 93% transparency, industry-leading brightness adjustment, and heat dissipation technology. IP68 protection rating allows RIGARD’s transparent LED displays to operate trouble-free in temperatures from -40°C to 60°C, and its pneumatic windproof design makes it resistant to storms and typhoons.


Transparent LED displays are gradually transforming the advertising and signage industry, and intangible features such as artificial intelligence and enhanced interactivity are additional benefits of the technology. So, whether it’s from reducing energy costs, boosting business, or enhancing innovative displays, there’s a reason to consider upgrading to a transparent LED screen solution.
