Abstract: This application discloses a power supply circuit, a driving apparatus, and a display apparatus, and relates to the field of display technologies. The power supply circuit includes: a first power supply module and a second power supply module. An output end of the first power supply module is connected to a first output end of the second power supply module, and is configured to be connected to a first input end of the driving module. An output end of the first power supply module is configured to output a first voltage signal, and a first output end of the second power supply module is configured to output a second voltage signal. A second output end of the second power supply module is configured to be connected to a second input end of the driving module, so as to output a third voltage signal.

Abstract: Methods and devices for controlling vibration of a motor are provided. In one aspect, vibration information generated by the motor in a vibration mode is collected, a first driving parameter is determined, where the first driving parameter is outputted by a drive circuit for the motor, and the first driving parameter is determined according to the vibration information and preset reference information, where the preset reference information corresponds to a type of the motor, and the preset reference information includes a correspondence a between feature parameter of the motor a driving parameter used by the motor when it is working in a stable state, and the drive circuit is controlled to drive the motor with the first driving parameter.
