Abstract
A contact light emitting device embodying the invention includes a transparent electrode layer and a luminescence layer. The electrode layer and the luminescence layer are configured such that an electric field can be generated between the electrode layer and an object to be imaged. When the object to be imaged is brought adjacent the luminescence layer, the luminescence layer emits light, which is then converted into an electrical signal.
