Title:
CLOCK FREQUENCY SWITCHING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/199446
Kind Code:
A1
Abstract:
The present application discloses a clock frequency switching method and apparatus, an electronic device, and a readable storage medium. The present application can solve the problem that the probability that the frame rate of the electronic device does not match the refresh rate increases due to MIPI clock frequency switching, resulting in an image display abnormality of the display screen. The method comprises: when it is detected that a clock frequency of an MIPI signal interferes with a radio frequency band of an electronic device, and first signal parameters of signals transmitted and received by a first antenna meet a first condition, obtaining second signal parameters of signals transmitted and received by a second antenna; and in the case that each second signal parameter meets the first condition, switching the clock frequency of the MIPI signal to a target clock frequency. The electronic device comprises at least two antennas; the first antenna is the antenna in the at least two antennas that has the largest interference with the MIPI signal; and the second antenna is the antenna(s) in the at least two antennas other than the first antenna.
