Abstract
The invention is a robust lensless instrument cluster configured for installation in a vehicle. The instrument cluster comprises an outer case, a PCB and lighting structure, an inner frame, an optical bonding assembly, halo lighting portions, a seamless display comprising tell-tale indicators and gauges, and an outer visor. The instrument cluster further comprises a plurality of LEDs for compartmentalized and indirect lighting of the tell-tale indicators on the seamless display and the halo lighting portions around the edges of the seamless display. Because the instrument cluster is lensless and otherwise exposed to the environment, it comprises a seal system to prevent the ingress of water and dust into the interior components. The seal system can also eliminate the risk of mura in the optical bonding assembly.
