Claim 15:
16. An electronic device, comprising:
a screen including a display and a cover plate;
a circuit board;
a middle frame located between the screen and the circuit board and including a first through hole and a second through hole, wherein the cover plate is located on one side of the display that faces away from the middle frame, wherein the display includes a first opening opposite to the first through hole and a second opening opposite to the second through hole, and wherein the first opening communicates with the second opening to be a whole;
an optical detection assembly, comprising:
a light shield body comprising:
a first end that includes an extension wall disposed in a circumferential direction, wherein the extension wall is disposed between the middle frame and the circuit board, wherein one side of the extension wall that faces the circuit board is hermetically connected to the circuit board, wherein the other side of the extension wall faces a middle board and is fixedly connected to the middle board;
a second end of the light shield body that passes through the first through hole and the first opening in sequence and extends to one side of the cover plate facing the middle frame; and
a light hole that penetrates from the first end to the second end, the light hole including a first hole segment and a second hole segment, wherein the first hole segment is disposed close to the first end of the light shield body, wherein the second hole segment is disposed close to the second end of the light shield body, and wherein a first stepped surface disposed toward the first end of the light shield body is formed between the first hole segment and the second hole segment;

a light sensor disposed on the circuit board and located in the light hole;
a lens disposed in the light hole, wherein a light inlet side of the lens is disposed toward the second end of the light shield body, wherein a light outlet side of the lens is disposed toward the light sensor, wherein a peripheral side of the lens includes a second stepped surface disposed toward the second end of the light shield body, wherein one end of the light inlet side of the lens extends into the second hole segment, wherein the second stepped surface is opposite to and fixedly connected to the first stepped surface, and wherein the lens is dark in color; and
a light homogenizing film disposed on the light outlet side of the lens, wherein the light homogenizing film is white; and

a camera module including an optical lens, wherein a light inlet side of the optical lens passes through the second through hole and extends into the second opening, and wherein a distance between the optical lens and the shield body of the optical detection assembly is less than 1 cm.
