Alternatively, as shown in fig. 1 and 2, the display screen 101 includes a cover plate 1011, a display layer 1012, and a conductive member 1013. Wherein the conductive member 1013 is used for electrical connection with other structures in the display device 100. Which may also be connected to the ground of the display device 100. The cover 1011 may be a glass cover or a sapphire cover that is positioned over the display 101 and covers the front of the display 101. The display layer 1012 may be an OLED layer or a Micro-LED layer.

In the thickness direction x of the display screen 101, the supporting member 104 and the conductive member 1013 are each provided with an opening at a position corresponding to the optical detection module 102 for enabling the optical signal to be emitted or received by the optical detection module 102.

The support 104 is located between the display 101 and the motherboard 106. Thus, the blocking member 107, similar to the embodiment shown in fig. 8, may be disposed directly on the optical detection module 102 to prevent crosstalk of light between the transmitting end 1022 and the receiving end 1021.
