The invention relates to a function display (1), in particular for a motor vehicle, for selectively displaying icons (18) representing switching functions and/or switching states, comprising: an outer transparent or translucent cover layer (23) defining a display surface (8); the invention relates to an optical waveguide stack consisting of at least two transparent or translucent planar optical waveguides (13, 14, 15) which are stacked in the stacking direction and which are arranged at a distance from one another by means of a transparent or translucent layer consisting of an optically thinner material than the adjacent optical waveguides (13, 14), preferably by means of an air gap (24), the light conductors (13, 14, 15) are arranged in the stacking direction such that each of the light conductors (13, 14, 15) has a main surface (H) facing the observer (B), in which at least one light conductor (13, 14, 15) a main surface (H ') facing away from the observer (B) faces the nearest light conductor (13, 14, 15) in the stacking direction; at least one light source (12) for each light conductor (13, 14, 15) arranged to couple light into the respective light conductor (13, 14, 15) through an end face (S) of the associated light conductor (13, 14, 15); wherein a light-refracting and/or light-scattering microstructure arranged in or on the light conductor (13, 14, 15) is also provided for each light conductor (13, 14, 15), said microstructure being suitable for displaying a backlight icon (18) visible to the observer (B) by means of light coupled into the light conductor (13, 14, 15) when activating a light source (12); and an operating element (10) and a steering wheel (20) comprising the function display.

    本发明涉及一种特别是用于汽车的用于选择性地显示表示开关功能和/或开关状态的图标(18)的功能显示器(1),其具有:定义显示面(8)的外部透明或半透明覆盖层(23);由至少两个在堆叠方向上叠置的透明或半透明的平面光导体(13、14、15)构成的光导体叠堆,所述光导体通过一个由与所述相邻布置的光导体(13、14)相比光学上更薄的材料构成的透明或半透明层,优选通过气隙(24)以彼此间隔一定距离的方式布置,使得所述光导体(13、14、15)各具有一个朝向观察者(B)的主表面(H),在至少一个光导体(13、14、15)中,背离所述观察者(B)的主表面(H’)朝向在所述堆叠方向上最近邻的光导体(13、14、15);针对每个光导体(13、14、15)的至少一个光源(12),其经布置以通过相关光导体(13、14、15)的端面(S)将光耦入相应的光导体(13、14、15)中;其中还针对每个光导体(13、14、15)设有设置在所述光导体(13、14、15)中或设置在所述光导体上的光折射和/或光散射微构造,所述微构造适于在激活光源(12)的情况下借助耦入所述光导体(13、14、15)中的光显示对于所述观察者(B)而言可见的背光图标(18);以及包含所述功能显示器的操作元件(10)盒方向盘(20)。
