Development of Metal Bonding for Passive Matrix Micro-LED Display Applications

Recently, there are many breakthroughs of display in the high resolution and vivid colors for applications in virtual/augmented reality. In this study, we have successfully developed a $64 \times 32$ array inline structure of a micro-LED ( $\mu $ LED) display by metal bonding an LED array with a glass circuit for connecting a passive matrix IC driver. The dimension of each $\mu $ LED was $100\...
