CLUSTER ILLUMINATION BY PIEZOELECTRIC MATERIAL

摘要

An instrument cluster for a motor vehicle includes a dial surface having a plurality of indicia located thereon. A pointer contacts the dial surface and is configured to rotate with respect to the dial surface. Piezoelectric material is disposed on one of the dial surface and the pointer. The piezoelectric material is configured to deform due to contact between the pointer and the dial surface.
