Abstract:
The present application provides a fingerprint recognition apparatus, a touch display apparatus and an electronic device. The fingerprint recognition apparatus comprises: an optical lens, which is located below a screen; and an image sensor, which is located below the optical lens, the image sensor comprising a pixel array having a plurality of pixel units; and a plurality of filter units, which are located above the plurality of pixel units and below the optical lens, the coverage area of at least one filter unit being greater or less than the area of one pixel unit. The plurality of filter units each comprise a transparent filter unit and a color filter unit of at least one color; and the image sensor is configured to receive an optical signal that is reflected by an object to be recognized above the screen and that passes through the optical lens and the plurality of filter units, so as to obtain a color fingerprint image, and the color fingerprint image is configured to determine whether the object to be recognized is a real finger. In the solution, color information of a finger is obtained by utilizing color filter units, so that the authenticity of the finger is effectively recognized.
