Abstract: A method for controlling dynamic change of a screen refresh rate and an electronic device are provided. In a scenario of dynamic change of the refresh rate, a refresh rate switching instruction may be sent immediately through an added refresh rate setting interface (displaySetFps) within a current ith frame period before a current Vsync periodicity ends. After receiving the refresh rate switching instruction, a DDIC drives a display screen to switch a screen refresh rate, and then the DDIC returns a new TE signal. After receiving the new TE signal, SurfaceFlinger starts a new Vsync periodicity corresponding to a switched screen refresh rate. In an embodiment of this application, a switching speed at which the screen refresh rate is switched may be increased by adding a new path. For example, it may be ensured that each switching of the screen refresh rate is completed within one frame.

Abstract: Embodiments of this application provide a method and system for measuring motor damping. In the method for measuring motor damping, a driving signal is generated to drive a to-be-tested motor to operate, and at a cut-off moment of the driving signal, the to-be-tested motor enters a free damping state and a turn-off signal is generated at this moment to cut off a test circuit of the to-be-tested motor. In this way, an acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state can be acquired, and damping of the to-be-tested motor is obtained by using the acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state, thereby realizing the measurement of the damping of the to-be-tested motor.

Abstract: Disclosed are a synchronization mechanism and a foldable terminal. In the synchronization mechanism, a first rotating component and a second rotating component are in transmission connection by using a first worm, a worm gear, and a second worm that are sequentially meshed, thereby implementing the synchronous rotation of the first rotating component and the second rotating component relative to a base. In addition, when the synchronization mechanism is applied to the foldable terminal, since an axial direction of the worm gear and a radial direction of the first worm and the second worm are consistent with a thickness direction of the body, and an axial size of the worm gear and radial sizes of the first worm and the second worm are relatively small, which is conducive to the light and thin design of the foldable terminal.
