Problems solved by technology

[0002] When the user uses the speaker to play audio and video files or make a phone call, the sound playback effect is relatively high. If the mobile industry processor interface (Mobile Industry Processor Interface, MIPI) of the display screen used to transmit data works at a fixed frequency, if If the crossover frequency or multiplier frequency falls on the operating frequency of the speaker, it will interfere with the speaker, causing noise or POP sound on the speaker, wh

Abstract

Embodiments of the present application disclose a display control method and related products. When an electronic device is sounding by a speaker, if the operating frequency of the speaker corresponding to the audio data to be played is detected to be within a first operating frequency interference range of a display screen MIPI, and the ratio of the interfered audio in the audio data is greater than a first preset threshold value, the operating frequency of the display screen MIPI is adjusted to a target frequency value, so that the ratio of the interfered audio in the audio data to be playedis smaller than a second preset threshold value, wherein the second preset threshold value is smaller than the first preset threshold value. Therefore, the operating frequency of the display screen MIPI can be dynamically adjusted under the application scene that the electronic device uses the speaker to play the audio without changing the hardware design of the electronic device, so that the electromagnetic interference to the speaker is eliminated or reduced, and the optimal communication performance is obtained.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a display control method and related products. Background technique [0002] When the user uses the speaker to play audio and video files or make a phone call, the sound playback effect is relatively high. If the mobile industry processor interface (Mobile Industry Processor Interface, MIPI) of the display screen used to transmit data works at a fixed frequency, if If the crossover frequency or multiplier frequency falls on the operating frequency of the speaker, it will interfere with the speaker, causing noise or POP sound on the speaker, and affecting the current audio playback effect. [0003] At present, the interference to the speaker can be improved through hardware upgrades, but it will increase the cost, and the improvement effect is limited, and directly adjusting the MIPI operating frequency of the display cannot ensure that the frequency division and mul...
