Hengyunlian: Be a disruptor in the field of LED transparent display
2023-12-21 18:23:28
At the 2023 Micro-Display Industry Conference, a little-known LED transparent screen company showcased "black technology" that received widespread attention from attendees. The various LED transparent screens they exhibited were able to remain clear and display images despite being submerged in water for an extended period of time, demonstrating excellent waterproof performance. Some screens were able to display text and images that were superior to regular outdoor displays even under intense sunlight. Adhesive films attached to glass screens did not generate heat even after being illuminated for a long period of time. Curiously shaped flexible transparent display modules could be assembled into a transparent display sphere. And their unique light drive separation technology solution was claimed to be the industry's only one. The LED transparent screen company that received attention was Shenzhen Qianhai Hengyunlian Technology Co., Ltd. (hereinafter referred to as "Hengyunlian"). When talking about Hengyunlian's disruptive technological innovation, company chairman Liu Jinhong always humbly claimed that although he has over 20 years of experience in the LCD and OLED display industry, he is still a "newcomer" in the LED field.
Cross-border LED display through "film"
The success of developing the flexible organic polymer film material was certainly, but Liu Jinhong encountered the same application as the South Korean display company. As a new product, its performance and advantages were not well known by the market, so the initial promotion was not too smooth. By chance, Liu Jinhong came into contact with LED transparent screens. As a branch of LED transparent screens, LED crystal screens are made through bare crystal planting technology, with transparent crystal film adhesive used for the board, transparent mesh circuits etched on the surface, and vacuum sealing adhesive used for the surface after components are attached. The film material used in LED crystal screens is similar to the heat-dissipating film of the flexible organic polymer film developed by Liu Jinhong, but upon comparison, he found many shortcomings in the film material used in LED crystal screens. Traditional adhesive film materials used in LED crystal screens have natural shortcomings. After being bonded with LED or IC light-emitting and heating devices, their heat dissipation performance is poor, they experience severe aging, yellowing, and color fading, and there is also the phenomenon of "bubbles", which seriously affects their lifespan and display effect. Liu Jinhong believes that if flexible organic polymer film is used to replace the traditional crystal screen film material, it will perfectly solve the pain points in the current crystal screen field. Therefore, he identified the application direction of flexible organic polymer film in LED crystal screens.
In order to make flexible organic polyester film better applied in LED crystal screen, Liu Jinhong began to study LED transparent screen. Although Liu Jinhong has been working in the display industry for more than 20 years and can be regarded as a senior professional in the display industry, in the process of studying LED transparent screen, Liu Jinhong found that there were still significant differences between some technical characteristics of LED display industry and past experience. When exploring the reasons, Liu Jinhong, as an "outsider" of LED, compared his rich experience in the display industry, constantly optimized the relevant design scheme, maximized the advantages of flexible organic polyester film, and made it a unique core patented technology.
Three years of silence, one striking
As an "outsider" in the LED industry, making the decision to crossover into the LED transparent screen field was difficult and painful. Since the idea of applying flexible organic polyester film to LED crystal screens emerged, Liu Jinhong and his R&D team were destined to embark on an extraordinary journey. After carefullying the current LED transparent screen and crystal screen fields, Liu Jinhong and his team specifically developed according to user needs and industry pain points, such as heat dissipation. Heat dissipation has always been a difficult problem in the LED transparent screen industry. Due to this packaging form, the light emitters and other devices are either completely sealed on the flexible PCB board or glass or in the adhesive film, and a large amount of heat cannot be conducted out, resulting in significant heating and screen failure, which seriously affects the lifespan of the screen and the industry image. In addition, some companies have adopted a "one-stop" solution to ensure the transparency of LED transparent screens, which not only increases the difficulty of heat dissipation but also leads to frequent display failures. Although some companies have adopted "breakpoint transmission" solutions, they only address the symptoms rather than the root cause and cannot fully meet signal transmission requirements.
In response to the above pain points, Liu Jinhong and the Hengyunlian team began targeted research and development. Combining flexible organic polyester film materials with the "light drive separation" scheme, Liu Jinhong and the Hengyunlian team developed a truly heat-free LED crystal screen. Even when illuminated and exposed to sunlight for several hours, there is no heating or blistering phenomenon on the screen body. The "light drive separation" scheme simplifies the circuit design to a greater extent, improving reliability and stability. What is most amazing is that when people have become accustomed to considering LED transparent screens as "semi-outdoor" (indoor installation, outdoor display) products, Hengyunlian's transparent screens already have full outdoor display effects. Using their unique lamp beads and material processes, they can achieve high-definition display of graphics and images in direct sunlight with only 4000 nits of brightness, comparable to traditional outdoor LED displays. The brightness of related outdoor LED displays is generally between 6000 nits and 10000 nits. This allows Hengyunlian's LED transparent screens not only to have outdoor high-definition display capabilities but also to have more significant energy-saving effects. On this basis, Hengyunlian combined solar energy and energy storage technology to develop zero-power consumption energy-saving LED transparent screens. According to their calculations, using solar photovoltaic conversion and energy storage devices, an average charge can last for three days. This product was highly regarded by the American highway department when exhibited abroad, and they are preparing to adopt it on a large scale on their highways.
The road of research and development is arduous and full of challenges. According to Liu Jinhong's requirement of "being the best in the industry", the R&D team of Hengyunlian has suffered a lot. At the time of the decision on research and development, it coincided with the COVID-19 epidemic raging around the world. Due to the high positioning standards, it was difficult to find suitable supporting materials across the country. For example, in the case of an IC connector, Hengyunlian finally found a manufacturer in Taiwan when no suitable supplier could be found in China, but the quotation for mold opening costs was as high as 1.85 million yuan for one product. Hengyunlian spent several million yuan on mold opening for this product alone. The entire transparent screen research and development cost tens of millions of yuan, which is a rare big deal for a start-up company in the field of LED transparent screen and even the LED display industry.
Due to its unconventional approach, Hengyunlian is destined to pay more than others. During the entire three-year epidemic period, despite the huge pressure of R&D costs, Liu Jinhong did not rush to bring the product to market, but constantly polished the product details until it was mature and capable of being fully launched on the market. The product has passed the double 85 cold and heat shock test for 1,000 hours and UV test, with a lifespan of up to 96,000 hours.
It is the pursuit of excellence in details that makes Hengyunlian's transparent screen a benchmark in the industry once it was unveiled. Whether it is the lamp beads, film materials, circuit design, or the "lamp drive separation" technical solution, or the energy storage and energy-saving solutions, it has amazed the industry and become a true industry disruptor.
When talking about the original intention of the cross-border LED transparent field, Liu Jinhong was filled with emotion: I originally wanted to promote film materials, but unexpectedly got involved personally and really started to work on LED transparent screens. This magnificent turnaround is not only a sublimation of his 20-plus years of display experience, but also a manifestation of responsibility and passion. He said frankly that the success of Hengyunlian is to tell the industry and users that there is still much room for improvement in LED transparent screen technology. As long as we are willing to study from the perspective of users, we will be able to solve some of the practical pain points of the industry and users.
Liu Jinhong pointed out that when planning products, Hengyunlian not only focuses on real industry needs and pain points, but also pays more attention to facing the future or adapting to international future needs. For example, energy conservation and environmental protection. Under the advocacy of a global low-carbon economy, countries are facing high-pressure leverage on carbon emissions, and only then will there be market demand for truly energy-saving products in the future. The situation of LED display screens claiming to be energy-saving but not energy-saving must be fundamentally changed, otherwise they will be ruthlessly eliminated by the market. Liu Jinhong candidly stated that in the future, outdoor LED displays will increasingly be combined with renewable green and clean energy such as solar energy to reduce energy consumption and lower user usage costs. Only then can LED displays truly become popular around the world, which will be more beneficial for Chinese enterprises to expand into the global market.
In terms of environmental protection, Liu Jinhong introduced the mandatory standards for electronic product recycling in Europe and America. If electronic waste products cannot be recycled, European and American users will not choose such products. He pointed out that the recycling rate of traditional LED displays is about 60%, while Hengyunlian has achieved a product recycling rate of 97%. It is not difficult to see that Hengyunlian is truly considering the needs of users, which also drives the industry to consider the value of waste recycling from the beginning of product manufacturing and material selection. This customer-centric philosophy also runs through all aspects of product planning, reflecting responsibility and accountability.
It is precisely because of this responsibility and responsibility that Liu Jinhong and the Hengyunlian team have always been at the forefront of the LED transparent screen industry with a disruptive attitude, and firmly believe in walking on the right path. Liu Jinhong believes that blooming alone is not spring, and the garden is full of colorful colors. Only with more and more LED transparent screen enterprises daring to research and develop, working together to progress, can the billion dollar transparent screen market become more and more prosperous. He called on responsible enterprises to adopt a user oriented and future oriented mindset, and work together to maintain the healthy development of the LED transparent screen industry.
With the recovery of the market, Hengyunlian has officially entered the market. With the influx of domestic and foreign orders, Hengyunlian has also ushered in its own shining moment. But Liu Jinhong still humbly stated that she will take every step with a down-to-earth attitude and strive to achieve a new cross domain of Hengyunlian.
