Display operating panel (10) comprising an at least partly light-transmissive operating plate (12), a plurality of light sources (14, 16, 42) and at least one detector (16, 18), wherein the operating plate (12) has an operating surface (20), the at least one detector (14, 16, 18, 42) detects the light emitted by the light sources (14, 16, 42) upon the operating surface (20) being touched, and the light sources (14, 16, 42) emit light modulated in a manner not directly perceptible to the human eye, wherein the light from the light sources (14, 16, 42) is individualized by a coding such that upon superimposition of the light from adjacent light sources (14, 16, 42) the emitting light sources (14, 16, 42) can be determined. |
