Display module and electronic device

An electronic device comprises a processor, a charging port, and memory that stores program code. When the program code is executed by the processor, the electronic device charges a battery of the electronic device using the charging port when a charger is connected to the charging port, stops charging in response to detecting that the charging port is abnormal, and displays a first window on a display interface of the electronic device in response to detecting that the charging port is abnormal. The first window comprises a first prompt information and a second prompt information. The first prompt information is used to prompt that liquid intake exists in the charging port, and the second prompt information is used to prompt a user to exclude a liquid intake situation of the charging port.

Charging method and related device

A chip package structure and a chip package method, the chip package structure including a die and a package substrate disposed around the die. A solder joint is disposed on a first surface of the die. Remaining surfaces of the die other than a second surface are wrapped by an injection molding material. At least one pair of opposite sides of the package substrate is embedded in the injection molding material. A contact area between the pair of opposite sides and the injection molding material accounts for more than half of a surface area of the pair of opposite sides. The second surface is a surface that is of the die and that is opposite to the first surface.
