Details
KBsphere Tech. has independently developed a new generation of polymer spacer microspheres and silica spacer microspheres. Featuring an extremely narrow particle size distribution, these microspheres enable precise control of cell gap thickness without damaging the substrate, while delivering superior clarity. In addition, KBsphere Tech. provides customized spacer microspheres tailored to customers’ specific requirements.
