1. A display panel, having a display area and a non-display area, comprising:

  • a plurality of pixels disposed in the display area;

    at least one driving circuit electrically connected to the pixels; and

    at least one photosensitive region having at least one photo detector electrically connected to the at least one driving circuit, the at least one photo detector, comprising;

    a substrate having a transistor region and a photosensitive region;

    a first patterned semiconductor layer disposed on the transistor region of the substrate, wherein the first patterned semiconductor layer comprises a first doping region and a second doping region;

    a dielectric layer covering the first patterned semiconductor layer of the transistor region, the photosensitive region, and the substrate;

    a first patterned conductive layer formed on the dielectric layer of the transistor region and on the dielectric layer of the photosensitive region;

    an interlayer dielectric layer covering the dielectric layer and the first patterned conductive layer, wherein the interlayer dielectric layer comprises at least two openings to expose a portion of the first doping region of the first patterned semiconductor layer and a portion of the second doping region of the first patterned semiconductor layer;

    a second patterned semiconductor layer disposed on the interlayer dielectric layer of the photosensitive region;

    two first electrodes formed on the interlayer dielectric layer and electrically connected with the first patterned semiconductor layer via the at least two openings respectively; and

    two second electrodes formed on the portion of the second patterned semiconductor layer.
