Photosensitive sensor and preparation method thereof, and electronic equipment

[0001] A photosensitive sensor includes: a substrate having a sensing region, a plurality of sensing units arranged in a regular pattern within the sensing region, a shielding layer disposed on the side of the sensing units away from the substrate, the shielding layer covering the sensing region, the shielding layer being made of a transparent conductive material, and the shielding layer being connected to a constant voltage signal terminal. This disclosure also provides a method for fabricating the photosensitive sensor and an electronic device thereof.
