In the related art, a screen used by a mobile phone, a pad and other electronic devices is generally a liquid crystal display (LCD) screen or an organic light-emitting diode (OLED) screen. Since the light-emitting principle of the OLED screen is different from that of the LCD screen, the OLED screen has advantages of smaller thickness, larger bendability, less power consumption, and more delicate colors, compared with the LCD screen, such that the OLED screen is widely acclaimed.

With the development of technology, the area of the display screen is getting larger and larger to provide users with better visual enjoyment. In order to increase a screen-to-body ratio of the electronic device such as the mobile phone, the design schemes of auxiliary functional components such as a camera and a fingerprint collection component have also changed accordingly. For the fingerprint collection component, there are mainly three arrangement schemes in the related art, namely a front arrangement, a rear arrangement and an under-screen arrangement. However, with the advent of the full-screen era, the schemes of the rear arrangement and the under-screen arrangement of the fingerprint collection component have become mainstream.
