[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] See also Figures 1 to 3 A dual-camera optical fingerprint recognition component 10 includes: a circuit board 100, an IC chip 200 and a camera 300, wherein the IC chip 200 is electrically connected to the circuit board 100, the number of the cameras 300 is at least two, the cameras 300 are electrically connected to the IC chip 200 and the circuit board 100 respectively, and the shooting direction of the camera 300 is toward a side away from the circuit board.

[0023] It should be noted that the dual-camera optical fingerprint recognition component 10 is provided with a camera 300. When the user places the finger in the camera 300 shooting area, the light source under the mobile phone screen will light up instantly, illuminating the user's fingerprint, so that the camera 300 captures the user's fingerprint image, and determines whether the fingerprint image is a fingerprint that has been recorded through the IC chip 200, and decides whether to unlock the user's mobile phone; in order to expand the scope of optical fingerprint recognition, the number of cameras 300 is set to at least two. In this embodiment, the number of cameras 300 is set to two, not only the camera 300 shooting area can recognize the fingerprint, but also the common area between the cameras 300 can recognize the fingerprint, so that the user can use a single hand to perform the fingerprint unlocking operation; the camera 300 is electrically connected to the IC chip 200 and the circuit board 100 respectively, so that the dual-camera optical fingerprint recognition component 10 can respond quickly and the overall structure is more compact.

[0024] See also Figure 2 In one embodiment, the dual-camera optical fingerprint recognition component 10 further includes a camera cover 400 , and the camera cover 400 covers the camera 300 .

[0025] It should be noted that, in order to improve the photographing accuracy of the camera 300 and enhance the clarity of the fingerprint image, a camera cover 400 is provided on the camera 300 to adjust the brightness of the fingerprint recognition environment.

[0026] Please refer again Figure 2 In one embodiment, card blocks 110 extend from both sides of the circuit board 100.
