An input panel having a display panel and a photosensitive detector panel, for controlling a data processing installation. Also disclosed is a method for operating such an input panel. In one preferred embodiment, the detector panel and the display panel are arranged at a distance from one another and the layer which adjoins the detector panel on the display panel side is an air layer. In a preferred mode of operation, a beam of light which is emitted by a light pointer device onto the input panel for the purpose of controlling the data processing installation has radiation components in two different spectral ranges, one radiation component being in the spectral range of visible light and the second radiation component being in the spectral range of IR light or UV light, with only the radiation component which is present as IR or UV light being absorbed by the detector panel. |
