Abstract
Embodiments of this application provide an electronic device and a signal transmission control method. A control module in the electronic device is arranged on a first printed circuit board, at least two functional modules are arranged on a second printed circuit board, and the at least two functional modules are electrically connected to the control module through a group of pin units of a connector. In addition, to avoid mutual impact between signals, a power supply module and a switch module electrically connected to the power supply module are arranged for each functional module, to implement signal transmission between the control module and each of the at least two functional modules in a time-sharing manner.

An electronic device, comprising:
- a first printed circuit board and a second printed circuit board;
- a flexible printed circuit, a first connector, and a second connector, wherein one end of the flexible printed circuit is electrically connected to the first printed circuit board through the first connector, the other end of the flexible printed circuit is electrically connected to the second printed circuit board through the second connector, and the first connector and the second connector each comprise a first pin unit, a second pin unit, and a third pin unit;
- a control module, arranged on the first printed circuit board;
- at least two functional modules, arranged on the second printed circuit board, wherein the at least two functional modules comprise a first functional module and a second functional module, and both the first functional module and the second functional module are electrically connected to the control module through the first pin unit of the second connector, the flexible printed circuit, and the first pin unit of the first connector;
- a first power supply module, electrically connected to the first functional module through the second pin unit, and configured to supply power to the first functional module;
- a second power supply module, electrically connected to the second functional module through the third pin unit, and configured to supply power to the second functional module;
- a first switch module, located between the first power supply module and the first functional module;
- and
- a second switch module, located between the second power supply module and the second functional module, wherein
- when the first switch module is turned on, the control module is configured to implement signal interaction with the first functional module, and when the second switch module is turned on, the control module is configured to implement signal interaction with the second functional module.
