Abstract

The application discloses a power supply circuit and an electronic device. The power circuit includes: a power chip, the power chip includes a power output terminal, and the power output terminal is used to output power signals to the display screen and the second display screen; the first switch unit connected between the power chip and the first display screen, the first When the switch unit is in the on state, the power supply signal is sent to the first display screen, and when the first switch unit is in the off state, the power supply signal is sent to the first display screen; and the second screen connected between the power chip and the second display screen Two switch units, when the second switch unit is in the on state, the power signal is sent to the second display screen, and when the second switch unit is in the off state, the power signal is sent to the second display screen, wherein the first switch unit and the second switch unit At least one of the two switch units remains in an off state. In this way, the quantity of the power supply can be single, which is beneficial to the miniaturization design of the electronic device.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a power supply circuit and an electronic device. Background technique [0002] As the application scenarios of display screens increase, on some electronic devices, the electronic device is configured with two or more display screens, each display screen corresponds to a power chip, and the power chip is used to provide power signals to the corresponding display screens. However, the space occupied by the power chip is large, which is not conducive to the miniaturization design of electronic devices. Contents of the invention [0003] The application provides a power supply circuit and an electronic device. [0004] The power supply circuit in the embodiment of the present application is used in an electronic device, the housing of the electronic device and the first display screen and the second display screen respectively arranged on opposite sides of the housin...
