Problems solved by technology

However, for long-term evolution (Long Term Evolution, LTE) broadband communications with a wide bandwidth, existing needs cannot be met between cells.
For example, for GSM, the elimination of interference frequency points can be achieved by clock signal jumping 2M, but to achieve the elimination of LTE interference frequency points requires wide-band jumps, such as 15M or higher frequency band jumps
The jump of the broadband will cause the frame rate of the display to change, especially at the moment of the jump, it is difficult for the display to be repaired temporarily

Abstract

The invention provides a frequency hopping method and a frequency hopping apparatus of a clock signal, a mobile terminal and a computer readable storage medium. The frequency hopping method comprisesthe following steps: when the first frequency of the clock signal of a display screen of the mobile terminal hops to the target frequency of the clock signal, obtaining a bandwidth between the first frequency of the clock signal and the target frequency of the clock signal; dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments, wherein N is an integer greater than 1; and according to the divided N segments of bandwidths, hopping the first frequency of the clock signal to the target frequency of the clock signal afterN times of hopping. By adoption of the frequency hopping method provided by the invention, the frame rate of the display screen is restored while wide band hopping is realized.

Description

technical field [0001] The present application belongs to the technical field of mobile terminals, and in particular relates to a clock signal frequency hopping method, a frequency hopping device, a mobile terminal and a computer-readable storage medium. Background technique [0002] The clock signal of the display screen of the mobile terminal is used as the instruction time for the display screen to work, and its interference to the radio frequency system has always been an urgent problem to be solved. For the global system for mobile communication (Global System for Mobile Communication, GSM) mode, the transfer of the interference frequency point can be realized through the hopping of the clock signal between cells. However, for long-term evolution (Long Term Evolution, LTE) broadband communication with a relatively wide bandwidth, existing demands cannot be met between cells. For example, for GSM, the elimination of interference frequency points can be achieved by clock...
