Abstract

The invention provides a control method and a terminal device. The terminal device comprises an LCM which comprises a liquid crystal display. The method comprises the following steps: when the liquidcrystal display is on, obtaining target channel information, wherein, the target channel information is channel information corresponding to a frequency multiplying point of a digital clock; obtainingregistration channel information based on registration information of the terminal device; when the target channel information includes the registration channel information, a supply voltage of the LCM driver chip is set to a target voltage, wherein the target voltage is smaller than a rated supply voltage of the LCM driver chip. In this way, the power supply voltage of the LCM driver chip is setto a target voltage smaller than the rated power supply voltage, thereby reducing the radio frequency interference caused by the frequency doubling component of the digital clock, thereby reducing the influence on the communication quality of the terminal equipment.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a control method and terminal equipment. Background technique [0002] With the rapid development of full-screen technology and terminal equipment technology, the driver chip of the Liquid Crystal Display Module (LCM) is getting closer and closer to the antenna area. The digital clock in the driver chip is used as a digital frequency source, and there will be frequency multiplication components. If its frequency multiplier falls within the communication frequency band, it will cause radio frequency interference, such as low call connection rate, navigation drift or slow Internet speed and so on. [0003] It can be seen that in the prior art, the radio frequency interference formed by the frequency multiplication component of the digital clock has a relatively large impact on the communication quality of the terminal device. Contents of the invention [00...
