Problems solved by technology
[0002] The improvement of the pixels of the display screen will generate a larger amount of data, which in turn requires the MIPI (Mobile Industry Processor Interface, Mobile Industry Processor Interface) bus used to transmit data to work at a higher and higher frequency, which will inevitably affect the antenna when it is working. Generate frequency multiplication interference, which will eventually reduce the receiving sensitivity of the antenna, and even affect the normal communication of the mobile terminal in severe cases

The invention discloses a display screen MIPI bus interference resisting method, including the following steps: acquiring a clock signal, wherein the clock signal includes multiple clock cycles, and each clock cycle includes a rising edge and a falling edge; acquiring a data signal, wherein the data signal includes multiple bit signals, the bit signals include high level signals and low level signals, one bit signal is transmitted at each rising edge, and one bit signal is transmitted at each falling edge; judging whether the data signal includes the continuous high level signals; and when thedata signal includes the continuous high level signals and the continuous high level signals correspond to at least one rising edge and at least one falling edge, inserting an adjustment signal intothe continuous high level signals, wherein the adjustment signal is a low level signal, and the adjustment signal is generated within the time period between the adjacent rising edge and falling edge.According to the scheme of the invention, the frequency doubling interference of the data signal can be reduced. The invention also discloses a display screen MIPI bus interference resisting system,an electronic device and a computer readable storage medium.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for resisting MIPI bus interference of a display screen, a system for resisting MIPI bus interference of a display screen, an electronic device and a computer-readable storage medium. Background technique [0002] The improvement of the pixels of the display screen will generate a larger amount of data, which in turn requires the MIPI (Mobile Industry Processor Interface, Mobile Industry Processor Interface) bus used to transmit data to work at a higher and higher frequency, which will inevitably affect the antenna when it is working. Frequency multiplication interference is generated, which eventually leads to a reduction in the receiving sensitivity of the antenna, and even affects the normal communication of the mobile terminal in severe cases.
