[0033] see image 3 , image 3 It is a schematic structural diagram of the display screen 100 provided by the first embodiment of the present invention. The fingerprint identification area 111 is a part of the display layer 110 , and the fingerprint identification area 111 is located in the middle area of the display layer 110 , and the fingerprint identification area 111 is surrounded by the peripheral area 114 . Such a structural design can adapt to the user's hand-holding posture, reduce the difficulty of unlocking the user's fingerprint, and increase the user experience. When the user unlocks the mobile terminal, the mobile terminal is placed on the palm of the hand. The position where the fingerprint of the thumb is located is the middle area of the display layer 110. The user does not need to move the position of the thumb, but directly sticks the thumb to the middle area of the display layer 110. Fingerprint identification area 111 can realize fingerprint unlock...

[0035] see Figure 4 to Figure 6 , is a schematic structural diagram of the display screen 100 provided by the second embodiment of the present invention. The fingerprint identification area 111 is a part of the display layer 110 , and the fingerprint identification area 111 is located at an edge area of the display layer 110 , and the peripheral area 114 is adjacent to the fingerprint identification area 111 . Such a structural design can realize the preparation of the transparent thin film transistor 112 , the transparent scan line 1107 and the transparent data line 1102 at the edge area of the display screen 100 . Compared with the first embodiment, there are fewer connections between the transparent scan lines 1107 and the opaque scan lines 1108, and fewer connections between the transparent data lines 1102 and the data scan lines, thereby reducing the number of transparent scan lines 1107 The probability of poor contact with the opaque scan line 1108 and the probabil...

[0037] see Figure 7 , Figure 7 It is a schematic structural diagram of the display screen 100 provided by the third embodiment of the present invention. The fingerprint identification area 111 is the entire display layer 110. Such a structural design increases the area of fingerprint identification on the one hand and reduces inaccurate identification or malfunctions caused by inaccurate placement of fingers; There is an obstacle on the fingerprint recognition area 111 of the 100, and the obstacle blocks the recognition inaccuracy or failure caused by the fingerprint recognition. In addition, fingerprint identification can be implemented at any position on the display layer 110, which increases user experience.
[0038] The present application does not limit the number of the fingerprint identification areas 111 . see Figure 8 There may be multiple fingerprint identification areas 111 , and the multiple fingerprint identification areas 111 are distributed on the displ...
