MAE team MassPrint Technology Group - wins gold medal in "Internet+" Innovation & Entrepreneurship Competition

MassPrint Technology Group, a team of NTU graduate and undergraduate students focusing on the commercialization of new mass transfer technology of Micro LED, won a gold medal in the 7th China International College Students’ “Internet+” Innovation & Entrepreneurship Competition on 14 October 2021. “Internet+” is an influential Innovation & Entrepreneurship Competition at the highest level in China.

In the display industry, Micro LED display is regarded as “the Ultimate Display Technology”. It is ultra-bright, ultra-clear, thinner and at the same time more energy efficient. It is much better than the OLED display technology. However, it has not become a common part of our daily live due to its high price. The price of Micro LED TV has remained as high as millions, several hundred times that of the conventional displays. It is due to its complex assembly process, known as Mass Transfer technology. Essentially, the technology requires soldering hundreds and thousands of LED chips on an area as small as a fingernail with very high accuracy. And all the LED chips are smaller than the width of a hair strand! Conventional mass transfer technologies have three limitations: efficiency, cost, and chip size. MassPrint Technology Group has developed a new mass transfer technology drawing inspiration from the aphid insect’s adhesive claw. Their new technology can increase the transfer speed up to 10,000 times and reduce the cost by more than 50%, with which mass production of Micro LED displays with high-efficiency and low-cost can become a reality.
