The Polaris Fixed Indoor 1.9mm COBALT (Chip-on-Board Advanced Light Technology) is Absen’s first Chip-On-Board solution. The Polaris series features a number of mechanical advances, including auto-lock, auto-eject and fast-switch curve-locking systems. The series also features a unique anti-collision PCB technology. The Polaris 1.9mm COBALT uses Absen’s NanoShield Technology, which encapsulates the LED chips with a layer of composite material that offers pixel protection from physical damage. Polaris also features on-board components, such as heat dissipation technology and 18-bit image processing, providing high contrast, grayscale and refresh rates.
