From 2014 to today, the display technology landscape has evolved rapidly, starting from the first generation of LCDs, moving through the second generation of OLEDs, and now reaching the promising era of Micro LED. This fast-paced development has brought about a wide range of innovations and competition in the market.
Currently, the industry is split between two major technologies: OLED and QLED. Both have made significant progress and are being aggressively promoted by manufacturers, leading to the emergence of high-quality products. While OLED is often hailed as "the next-generation display technology" and QLED aims to achieve self-luminescence in the future, their ultimate goal remains the same — to eventually replace traditional liquid crystal displays and dominate the market.
These two technologies have already found their place in premium devices, but they now face a new challenge from Micro LED, a rising contender with great potential. Micro LED offers several advantages, such as superior brightness, energy efficiency, and longevity, making it a natural choice for future display panels. However, despite its promise, Micro LED still faces hurdles like low yield rates, high LED density, and complex manufacturing processes, which have led many in the industry to believe that commercialization is still far off.
Still, there are signs that Micro LED might be closer than expected. Samsung recently announced that its 146-inch MicroLED TV, "The Wall," will be released in August. This move suggests that the technology may be advancing faster than previously thought.
Micro LED works by miniaturizing and arraying traditional LED crystals using micro-processing techniques, then transferring them onto a circuit board via mass transfer technology, followed by physical deposition to create a protective layer. The key to this process lies in two core technologies: micro-processing and mass transfer.
For years, these technologies were not fully developed, causing repeated delays in mass production. To overcome these challenges, companies like Jingyuan Optoelectronics, Sanan Optoelectronics, and Dry Photoelectricity have invested heavily in R&D.
Recently, a major breakthrough was announced in the field of Micro LED technology. A UK-based company called Optovate Ltd. has developed a revolutionary method that allows multiple Micro LEDs to be transferred from a wafer to a substrate in a single step, enabling precise optical arrays.
Optovate's advancements include two key innovations. First, they created a unique transfer technology that can extract Micro LEDs from a wafer and place them on the backplane for both display and illumination purposes. This approach supports large substrates and offers a cost-effective solution for Micro LED applications.
Second, they developed a method to produce and integrate precision optical arrays that combine light emission and reflection from each Micro LED. This technology brings significant benefits for various applications, including displays, LCD backlights, and solid-state lighting, offering thinness, low power consumption, and controllable illumination.
These two innovations in Micro LED transfer and optical control can be used independently or combined with other methods. Optovate’s breakthrough could significantly speed up the mass production and commercialization of Micro LED, potentially disrupting the display and LED lighting industries.
With ongoing developments and increasing investment, the future of Micro LED looks brighter than ever. It may not be here yet, but it's definitely coming soon.
