The invention relates to a functional display, comprising: at least one planar light guide made of at least one transparent or translucent first material, having two opposite main surfaces and at least one end surface, one main surface facing an observer as a display surface and the other main surface facing away from the observer; the at least one light source is arranged to emit light of the light source into the light conductor from the end face of the light conductor; at least one main surface of the light conductor is surface-structured by means of a plurality of light-refracting and/or light-scattering microstructures introduced into the respective main surface; a coating applied only locally to the surface structured region of the main surface, the coating being formed from a transparent or translucent second material; when the light source is activated, light incident into the light guide is caused to exit in the direction of the observer by means of light refraction and/or light scattering in the uncoated symbol region, such that the symbol generated and illuminated by the uncoated surface-structured symbol region is visible to the observer.
本发明涉及一种功能显示器,具有:由至少一种透明或半透明的第一材料形成的至少一个平面光导体,具有两个彼此相反的主面和至少一个端面,其中一个主面作为显示面面向观察者并且另一个主面背离观察者;至少一个光源布置为由光导体的端面将光源的光入射到光导体中;光导体的至少一个主面借助于被引入到相应主面中多个起折射光和/或散射光作用的微结构而被表面结构化;仅局部施加于主面的表面结构化的区域上的涂层,涂层由透明或半透明的第二材料形成;在光源激活的情况下通过在未涂覆的符号区域中的光折射和/或光散射促使入射到光导体中的光向观察者的方向出射,使通过未涂覆的表面结构化的符号区域产生且照亮的符号对于观察者而言是可见的。
