Problems solved by technology

[0002] When the user uses a microphone to record or make a voice call, the requirements for collecting sound are relatively high. If the display mobile industry processor interface (Mobile Industry Processor Interface, MIPI) used to transmit data works at a fixed frequency, its frequency division frequency Or the multiplier frequency will have a certain impact on the microphone. When the influence coefficient is too large, it will cause poor call effect or unclear recording, which will affect the use effect of the microphone.
[0003] At present, the interference to the microphone can be improved through hardware upgrades, but it will increase the cost and the improvement effect is limited. Directly adjusting the MIPI operating frequency of the display cannot guarantee that the frequency division and multiplication frequency point will have the least impact on the microphone, and may also affect the display effect. influential

Abstract

The embodiment of the invention discloses a display control method and related products. The method comprises the following steps of: acquiring a first MIPI working frequency of a display screen mobile industry processor interface MIPI when an electronic device collects audio through a microphone; determining an impact coefficient of the first MIPI working frequency on the microphone, judging whether the influence coefficient is larger than a preset worst threshold value or not; adjusting the working frequency of the display screen MIPI to a target frequency value if the influence coefficientis larger than the preset worst threshold value, so that the influence coefficient of the display screen MIPI to the microphone is smaller than a preset feasible threshold value. According to the display control method and the related products, the working frequency of the display screen MIPI can be dynamically adjusted under the scene that the electronic device uses the microphone without changing the hardware design of the electronic device, thereby eliminating or reducing the electromagnetic interference of the microphone, and obtaining the optimal audio acquisition performance.
