Has a huge amount of transfer technology been broken? Micro LEDs come faster than you think!
From 2014 to the present, from the first generation of LCD, to the second generation of OLED, to today's Micro LED, the display technology market has undergone tremendous changes.
At present, manufacturers are divided into two different camps of OLED and QLED, and they have begun to vigorously promote their technology and gradually emerged a large number of excellent products. However, whether it is the OLED called "next-generation display technology" or the QLED that will realize self-luminescence in the future, the ultimate goal is to replace the liquid crystal and become the new hegemon.
These two display technologies have actually gained a foothold in high-end products, but they are also facing the threat of the new challenger Micro LED.
As we all know, Micro LED does have a very good advantage. It is a natural display technology panel material, but it still has problems such as high yield, high LED density and complicated components. Therefore, for the commercialization of Micro LED, the industry generally believes that "it is too early."
However, it is worth mentioning that Samsung has announced that the 146-inch MicroLED TV "The Wall", which was previously unveiled at CES, will be released in August. Looking at the 146-inch Micro LED display device that Samsung exhibited at CES, the Micro LED seems to come earlier than we expected.
In fact, Micro LED is mainly used to miniaturize, array, and thin the traditional LED crystal film by micro-process technology, and then transfer the crystal film to the circuit board by mass transfer technology, and use physical deposition to manufacture the protective layer. Package. Therefore, its key core technologies have two main steps: micro-process technology and massive transfer technology.
Previously, because these two key core technologies were not well resolved, the mass production process of Micro LEDs was repeatedly delayed. In order to solve this technical bottleneck, LED companies such as Jingyuan Optoelectronics, Sanan Optoelectronics, and Dry Photoelectricity have invested a lot of resources in research and development.
Recently, there has been a big news in the field of Micro LED technology, and huge transfer technology has made a major breakthrough. It is reported that Optovate Ltd., a MicroLED optical specialist based in Oxfordshire, England, has announced that they have developed a MicroLED technology that can transfer multiple MicroLEDs from a wafer to a substrate in a single step to achieve a precise optical array.
It is understood that Optovate has made two major breakthroughs in its Micro LED. First, it developed a unique Micro LED transfer technology that can extract Micro LEDs from the wafer onto the backplane for display and illumination. This approach extends to large substrate sizes and provides a cost-effective way for Micro LED applications.
Second, Optovate has also developed a method for producing and integrating precision optical arrays that combine the light and light reflections of each Micro LED for a variety of displays, LCD backlights and solid-state lighting with controllable illumination and super Significant advantages such as thinness and low thickness.
These two innovations for Micro LED transfer and light control of micro-optical components can be combined with other methods or used separately.
Optovate's technological breakthroughs or accelerate the mass production and commercialization of Micro LEDs, its patented technology has the potential to break the display and LED lighting value chain.
