Hola-LED chooses to build its pilot line, and through independent innovation, breaks through several key technologies, and has laid out several micro-LED production lines. Shortly, it is expected to start and build the world’s first glass-based Micro-LED display production line.
Three years ago, when OLED, the mainstream technology route, was flourishing, Hola-LED, one of the leaders of the emerging display industry in China, made a bold decision: Take a step forward, bet on Micro-LED in the complicated technical route, and reached deep cooperation with LED display and LED display control system manufacturers such as Kinglight, Nova Technology, Colorlight, specializing in Micro-LED project, quickly landing pilot line.
In the eyes of the industry, 1.2 billion yuan has been invested in the construction of only one pilot line. So where did Hola-LED’s courage come from?
At that time, China’s new-type display industry was gathering rapidly, with an average annual growth rate of 30 percent, taking its place in the national industrial landscape. However, compared with the Bohai Rim region with Beijing as the core and the Yangtze River Delta region represented by Hefei, Shanghai, and Nanjing, Shenzhen is more focused on the construction of large-scale production lines and lacks industry-leading products. Focusing on the future of industrial development, Hola-LED hit it off immediately and planted its industrial seeds, just to cultivate the future display of industrial ecology.
Until now, this seems to be an advanced layout, both the international leader Samsung, as well as the domestic leader BOE, focus on the OLED technology upgrade. It also means that the technological innovation required for this pilot line is extremely demanding.
To industrialization, Micro-LED has many technical problems which cannot be bypassed. At the heart of the technology is the transfer of all the tiny light-emitting diodes onto a TFT (thin film transistor) substrate, a precision assembly technique known as “mass transfer”, which involves robots picking up tiny LED chips from the substrate, transferring them to a smaller TFT backplane, and then assembling the resulting modules into the final display.
Those who can break through the technical difficulties will be one step ahead in Micro-LED and will have the right to speak in the future display. Hola-LED chose self-built micro-LED production lines to break through technical difficulties steadily.
A large number of key technological breakthroughs can be seen in the screen samples produced by Hola-LED. Six single screens are seamlessly stitched together to create a 12.7-inch screen featuring the head of a furry tiger. This is the first time in the world that a 25-micron chip has been used to make the tiny screen, with 520,000 LED chips evenly distributed across the screen, each about half the size of a human hair.
As of press time, the pilot line created by Hola-LED is still under continuous testing. It is believed that within three years, it will bring the world a major surprise. Micro-LEDs allow screens to be edgeless, allowing for arbitrary splicing. As a new technology route, it can also make the screen thinner, brighter, clearer, longer life, lower cost… Let’s look forward to it!
