Abstract

The flexible circuit board, display screen and electronic equipment provided by the embodiments of the present application relate to the field of display technology. During bonding, the circular pad area is heated and expands. Due to the existence of the through hole, the flexible circuit board can be squeezed toward the through hole. Release the radial expansion pressure, which can weaken the radial offset of the pad in the circular pad area, thereby reducing the loss of the effective bonding area of ​​the flexible circuit board during the bonding process and ensuring flexibility after bonding The circuit board has a large effective bonding area. It can ensure that different flexible circuit boards have a large pull-out force after bonding and are not easy to separate. At the same time, because the effective bonding area is less lost, the impedance of the signal transmission channel after bonding is less increased, and the anti-interference ability in the signal transmission process is strong. An abnormality in signal transmission or a large increase in transmission power consumption can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a flexible circuit board, a display screen and an electronic device. Background technique [0002] With the update and iteration of electronic devices, the functions of electronic devices are increasing, and the number of lines is also increasing. When bonding different flexible printed circuits (FPCs), the number of pads to be bonded will also increase, and the difficulty of bonding will also increase accordingly. The increase in the difficulty of bonding will directly lead to anomalies such as separation or signal interference after bonding of different flexible circuit boards. How to solve the above exception is a technical problem that those skilled in the art need to solve urgently. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a flexible circuit board, a display screen, and an electronic device, so as to overcome the te...
