Patent ID: 8454894

Claim:
A device for evaluating biochemical samples, the device comprising a sample carrier an image recorder comprising a light-sensitive layer connected to an evaluation circuit, wherein the light-sensitive layer, provided on the sample carrier of the image recorder comprises a photoactive layer based on organic semiconductors between two electrode layers of which the electrode layer between the photoactive layer and the samples is translucent at least in certain regions; wherein the two electrode layers for the photoactive layer are constructed from intersecting strip conductors which delimit, in the region of intersection, light-sensitive elements in the photoactive layer; wherein the photoactive layer forms light-emitting elements in selected regions of intersection of the strip conductors of the two electrode layers, the light-emitting elements in the photoactive layer being adjacent to but separate from the light-sensitive elements in the photoactive layer; wherein the photoactive layer has a construction in the region of the light-emitting elements differing from a construction in the regions of the light-sensitive elements; wherein the evaluation circuit is configured to read out output signals from the light-sensitive elements; and wherein the photoactive layer simultaneously: emits light via the light-emitting elements, and senses light via the light-sensitive elements such that the light-sensitive elements generate the output signals and such that the evaluation circuit reads out the output signals.
