Description

Electronic device

Technical Field

The invention relates to the technical field of a flat cable structure in electronic equipment, in particular to electronic equipment.

Background

At present, electronic equipment such as mobile phones and tablet computers are equipped with a fingerprint unlocking function, and commonly used fingerprint schemes include screen fingerprints, back fingerprints and the like. The two fingerprint schemes are adopted, wherein the screen fingerprint is usually used on the electronic equipment made of the OLED screen material; while backside fingerprints are mostly used in TFT screen electronics. At present, some electronic devices adopt side fingerprints, the side fingerprints have many advantages, the first advantage is that the electronic devices can be unlocked at any time, if the fingerprints under the screen can be unlocked only by using a fixed finger within a specified range, but the side fingerprints can be unlocked only by using a mobile phone at any time at a safe position, and in addition, the appearance of the mobile phone can be more uniform, and the overall coordination of the mobile phone (the screen occupation ratio can be improved) cannot be damaged due to the unlocking of one fingerprint; moreover, the unlocking speed of the side fingerprints is faster, the technical scheme is relatively simple to implement, and the practicability is relatively high.

In the technical scheme that the side fingerprints are distributed on the side face of the mobile phone, the side fingerprints need to be connected with a main board, and the side fingerprint module is generally connected with the main board through an FPC (flexible printed circuit); in the conventional technology, the FPC is connected to the main board of the mobile phone through the top of the battery (i.e., between the battery and the battery cover plate), and the thickness of the fingerprint FPC is generally 0.12-0.15mm, which results in an increase in the overall thickness of the electronic device by 0.12-0.15mm, which is very disadvantageous to the light and thin design of the electronic device and increases the overall thickness of the electronic device.
