FIG14 illustrates a display device 200 according to an embodiment of the present disclosure. The display device 200 includes the display screen 100 according to any of the above embodiments, an optical fingerprint module 202, and a frame 201. The display screen 100 and the optical fingerprint module 202 are fixed on the frame 201. The optical fingerprint module 202 is located on one side of the display screen 100 intended to away from a user. The optical fingerprint module 202 is located in a position corresponding to the fingerprint recognition area 111, whereby light signals transmitted or received can pass through the fingerprint recognition area 111. The optical fingerprint module 202 includes a light emitter 203 and a light inductor 204. The light emitter 203 is configured to emit light signals b and the light inductor 204 is configured to receive light signals c. When a finger is in contact with a surface of the display screen 100, lights transmitted from the light emitter 203 form incident lights b, and incident lights b sequentially pass through the through hole 121 and the fingerprint recognition area 111 of the display layer 110 to be projected onto patterns of a finger 205. Since the display layer 110 corresponding to the fingerprint recognition area 111 is provided with first thin-film transistors 113, first scan lines 115, and first data lines 117 arranged at large intervals, transmittance in the display layer of light signals b can be improved, and the intensity of incident lights b projected onto the patterns of the finger 205 can be increased. Accordingly, the intensity of reflected lights c formed from incident lights b reflected by the patterns of the finger 205 can also be increased. When reflected lights c, which is formed from reflection of the patterns of the finger 205, sequentially pass through the fingerprint recognition area 111 and the through hole 121 to be projected to the light inductor 204, transmittance of light signals c in the fingerprint recognition area 111 of the display layer 110 can also be increased, and intensity of light signals c received by the light inductor 204 can be increased, thereby increasing the accuracy of fingerprint recognition of the optical fingerprint module 202.  Referring to FIG13, the display screen 100 may further include a light-shielding layer 120. The light-shielding layer 120 is disposed on one side of the display layer 110 intended to away from a user. The light-shielding layer 120 defines a through hole 121. The through hole 121 is located in a position corresponding to the fingerprint recognition area 111, whereby the optical fingerprint module can transmit and receive light signals through the fingerprint recognition area 111 and the through hole 121. In an embodiment, the shape and size of the through hole 121 is the same as that of the fingerprint recognition area 111. An orthographic projection area of the through hole 121 on the display layer 110 coincides with the fingerprint recognition area 111.
