US 11,535,103 B2 · Lensless instrument cluster with integration of hard telltales and halo lighting providing a seamless display appearance

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.

Dependent claims

A lensless instrument cluster configured for installation in a user environment, the lensless instrument cluster comprising:

an outer case;
a printed circuit board and lighting structure assembly connected to the outer case;
an inner frame connected to the printed circuit board and lighting structure assembly;
an optical bonding assembly connected to the inner frame;
a halo lighting portion;
a seamless display comprising:
a main display portion comprising a gauge;
a tell-tale surface comprising a tell-tale indicator;
and
an outermost surface that is in direct contact with the user environment;
a compression system disposed between the optical bonding assembly and the printed circuit board and lighting structure assembly, wherein the compression system is configured to prevent mura from occurring in the optical bonding assembly due to pressure applied to the optical bonding assembly.
