The invention relates to a functional display, comprising at least one light guide, which has a planar display part, which has two opposite main surfaces which face a viewer as display surfaces and the other main surface which faces away from the viewer, and which further comprises at least two light input parts, a plurality of light sources into which light is incident via one of the plurality of light input portions of the light guide that is immediately adjacent to the respective light source; at least one of the main surfaces of the light guide display part is surface-structured by means of a plurality of microstructures introduced into the respective main surface causing light refraction and/or light scattering, such that at least two surface-structured interface regions act as sub-regions of the respective main surface in the light guide; the sub-regions are staggered in the transverse direction from the viewer angle and represent symbols; when the light sources are activated respectively, light incident into the light guide exits towards the viewer due to light refraction and/or light scattering in the surface-structured interface region.
本发明涉及一种功能显示器,具有至少一个光导,光导具有平面的显示部分,该显示部分具有两个相对置的主表面,其作为显示面面向观看者,而另外的主表面背离观看者,光导还具有至少两个光输入部分;多个光源,光经由光导的多个光输入部分中的紧邻相应光源的光输入部分中的一个射入到光导中;光导显示部分的主表面中的至少一个主表面借助于多个引入到相应主表面中、造成光折射和/或光散射的微结构而表面结构化,以使至少两个表面结构化的界面区域作为光导中的相应主表面的子区域;子区域从观看者角度在横向方向上错开地布置且表示符号;当分别激活光源时,由于表面结构化的界面区域中光折射和/或光散射造成射入到光导中的光向着观看者射出。
