Abstract
A ridge recognition substrate and a ridge recognition apparatus. The ridge recognition substrate includes: a base substrate including a photosensitive area, and a light-shielding area located on at least one side of the photosensitive area; a plurality of photosensitive devices, arranged in the photosensitive area in an array; each photosensitive device includes a first electrode, a photoelectric conversion structure and a second electrode arranged in layers, the photoelectric conversion structure is electrically connected with the first electrode, and the photoelectric conversion structure directly contacts with the second electrode; and dummy devices, arranged in the light-shielding area in an array, each dummy device including a third electrode, an equivalent dielectric layer and a fourth electrode, the third electrode and the first electrode is in the same layer, the fourth electrode is located at the side of the layer where the second electrode is located facing away from the base substrate.
