Latest Patents
Koo's latest patents include a groundbreaking invention titled "Liquid crystal on silicon micro-display using carbon nanotube." This nano-liquid crystal on silicon (nano-LCoS) chip features carbon nanotube (CNT) pillars that are grown on a glass substrate. The uniform height of the CNT pillars allows them to function as spacers, providing a consistent cell gap between the glass substrate and the silicon chip. Additionally, the CNT pillars serve as excellent electrical conductors, forming part of the electrical connection between an external voltage source and the indium tin oxide (ITO) layer on the glass substrate. The nano-LCoS chip also includes alignment keys connected to the CNT pillars, which, when activated by voltage, create transparent fiduciary marks for optical alignment of the nano-LCoS chips.
Another notable patent by Koo is titled "Carbon nano tube technology in liquid crystal on silicon micro-display." This invention shares similar features with his previous patent, emphasizing the innovative use of CNT pillars for enhancing the performance and functionality of nano-LCoS chips.
