Abstract
An optoelectric sensor, comprising: a light-sensitive structure which comprises a substrate and an array of pixel cells located on the substrate, wherein each of the pixel cells comprises a thin film transistor and a photodiode; a fiber optical guide plate located above the light-sensitive structure, which comprises a group of optical fiber bundles configured to be perpendicular to the substrate, and each of the optical fiber bundles has an diameter smaller than or equal to a width of pixel cell; and a backlight source located below the light-sensitive structure. The fiber plate will enable each pixel cell detecting features of an object surface corresponding thereto more independently, so as to improve the resolution of the optoelectric sensor. The optical fiber bundles are configured to be perpendicular to the substrate, and the optoelectric sensor will have a thin structure.
