Abstract

A device for displaying information and for capture of prints of a plurality of skin areas of human autopodia by means of reflection, comprising: a placement surface for applying the autopodia, a touch-sensitive layer, an LC unit with pixels arranged which are individually controllable by a control unit, an illumination unit with a transparent light-guide-layer body, first and second illumination means, and an optical sensor layer with sensors below the light-guide-layer body. The first illumination means emits diffuse light in a first wavelength range, and the second emits directed light in a predefined angular range and in a second wavelength range. The sensor elements are sensitive to light of the second wavelength range. The pixels are switchable between a state which is transparent to the diffuse light and directed light and a state which is opaque to the diffuse light, and are illuminated by the diffuse light for displaying information.
