Kim's team is focusing on Nano LEDs, which they believe will be the next step in display technology evolution, following OLEDs and micro LEDs. While micro LEDs are currently considered advanced, they still face certain challenges, particularly with the color blue. However, Nano LEDs offer improved efficiency, especially for blue colors, making them a promising alternative. The research indicates that combining blue Nano LEDs with quantum dot technology could enhance display performance.
The main advantage of Nano LEDs is their tiny size, allowing for a higher density of LEDs in a given area, which can lead to defect-free pixel designs and lower chip costs. This compactness also means less material consumption, contributing to overall cost reduction. Moreover, the team has developed a transfer process that is simple and fast, addressing significant commercialization hurdles related to chip cost and transfer technology.
During recent demonstrations at industry booths, Kim's team showcased Nano LED displays, emphasizing their impressive visual quality. Although still in the early stages, their displays have achieved over 99% LED coverage. The goal is to eliminate the need for redundant pixels, aiming for about 69-79% active pixel coverage. This level of efficiency allows the remaining surface area to be used for other functionalities like sensors, which can be particularly beneficial for large displays such as televisions.
For applications like AR and VR, the compactness of Nano LEDs is crucial. These devices require extremely small displays with minimal unused space. Kim's team employs a unique approach to pixel creation and assembly, differing from traditional bonding technologies. Instead of growing and bonding pixels, they process them on flat wafers, lift them from substrates, and reassemble them on any desired substrate. This innovative method simplifies the manufacturing process and potentially reduces costs.
The manufacturing process for Nano LEDs involves sophisticated vacuum tools and other advanced equipment. While it might seem like a solution-based process, it heavily relies on precise technologies like E-beam technology for creating and assembling Nano LEDs. Despite the complexity, this process is essential for achieving the high precision and quality required for Nano LED displays.
Kim's team stands out in the industry, as not many are working on Nano LED technology. Their approach, developed initially at H University, has led to the formation of a spin-out company focused on commercializing Nano LED displays. This company aims to bring these displays to market within the next three years, provided they secure the right investment and partnerships.
Overall, Jaekyun Kim is optimistic about the future of Nano LEDs, believing they represent the next major advancement in display technology. He has received significant interest from major companies looking to incorporate Nano LEDs into their future products. The combination of enhanced efficiency, reduced costs, and innovative manufacturing techniques positions Nano LEDs as a transformative technology in the display industry.
