Abstract
In a pointer instrument ( ) having a pointer shaft ( ) that deflects a pointer flag ( ), the pointer flag ( ) can be illuminated by means of a light source ( ). For this purpose, the light source ( ) is formed, for example, as a light-emitting polymer ( ), which is applied between the pointer flag ( ), which is formed at the same time as an electrode, and a further, transparent electrode ( ), and emits light of any desired coloration under appropriate electrical excitation. The pointer flag ( ) can assume any desired shape as the result of using such a light source ( ) that can be shaped. In particular, multiple curvatures can be represented without differences in brightness occurring in this case.
