Abrégé

The present disclosure is related to reducing shake and vibration in Head-Up Displays (HUDs) under dynamic operating conditions. The apparatus includes a curved mirror for projecting an image from a display unit on a windshield of a vehicle. The curved mirror has damping tape on its nonreflective side to absorb vibrational energy and shift the first natural frequency of the curved mirror to a higher frequency. The damping tape includes at least a viscoelastic adhesive layer and a constraining layer. The method for stabilizing the HUD includes applying damping tape selected and positioned to reduce vibrational amplitude and shift the first natural frequency of the curved mirror to a higher frequency.

Abrégé

The invention is a robust lensless instrument cluster configured for installation in a vehicle. The instmment 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.

Abrégé

A composite instrument panel having both an electronic display and an opaque dial plate is provided with features that mimic a seamless electronic display. The instant panel includes an electronic display and an applique having a translucent or transparent window through which the electronic display is viewable, and an opaque area adjacent the window defining a dial plate upon which indicia can be printed, the transparent or translucent window having a peripheral border area that transitions from transparent or translucent at an inner edge of the border nearer a center of the window to opaque or nearly opaque at an outer edge of the border farther from the center of the window.

Abrégé

An illuminable pointer assembly for an instrument panel includes a transparent or translucent base, a transparent or translucent pointer blade, and a hub mounted on the base and supporting the pointer blade. The assembly is miniaturized or capable of being miniaturized by integrating reflectors into a lower surface of the pointer blade to internally reflect light propagated upwardly through the base in a lateral direction to uniformly illuminate the pointer blade.
