Abstract
The present application belongs to the field of display technology, more particularly, relates to a display component and a display device. The display component comprises a display panel having a plurality of pixel structures. A packaging film is provided above the display panel. In each of the pixel structures, a control element and a photosensitive element connected with the control element are provided above the packaging film. The photosensitive element performs fingerprint identification according to received reflection light reflected by a finger after being emitted by the display panel. The display component implements optical fingerprint identification based on the display panel. By providing the photosensitive elements and respective control elements above the packaging film, accurate fingerprint identification is implemented.
