Description

Voltage regulation method, electronic equipment and related device Technical Field The present application relates to the field of electronic technologies, and in particular, to a voltage adjustment method, an electronic device, and a related apparatus. Background With the increasing development of terminal technology, electronic devices (such as mobile phones, tablet computers, etc.) are increasingly used. The display screen is an important device of the electronic equipment, and in order to ensure that the display screen of the electronic equipment can be lightened, power supply is needed to be performed on the display screen. However, due to the fact that the Electro-Static-Discharge (ESD) generates an instantaneous voltage, a signal error transmitted by a system-in-chip of the electronic device to the display driving chip is easily caused, and then the display driving chip controls the power management chip to supply power to the display screen abnormally, and the abnormal power supply possibly breaks through a transistor in the display screen, so that the display screen is burnt, and poor use experience is brought to a user. Disclosure of Invention The voltage regulating method, the electronic equipment and the related device provided by the embodiment of the application can reduce the probability of burning the display screen due to overlarge voltage and improve the use experience of a user. In a first aspect, the present application provides a voltage regulation method applied to an electronic device, where the electronic device includes a display screen, the method includes: When the electronic equipment is powered on, a first voltage is applied to the display screen, wherein the first voltage has a first value; generating a first adjustment signal when the first voltage acting on the display screen is detected to be a second value, wherein the second value is larger than the first value; the first voltage is adjusted based on the first adjustment signal such that the first voltage acting on the display screen is from the second value to the first value. In the above method, after the electronic device is powered on, a first voltage is applied to the display screen so that the display screen can be lit. The first voltage may be regarded as a voltage for lighting the display screen, for example. After the electronic equipment is powered on, if the first voltage is detected to be abnormal, for example, the value of the first voltage is from the first value to the second value, in order to avoid the display screen being burnt out due to the fact that the display screen is in a high-voltage state for a long time, the electronic equipment can generate a first adjusting signal, and then the first voltage is adjusted based on the first adjusting signal, so that the value of the first voltage is from the second value to the first value, the value of the first voltage is pulled down, the display screen is pulled to a normal state from the high-voltage state, the probability of burning out the display screen due to overlarge voltage is reduced, and the use experience of a user is improved. In a possible implementation manner of the first aspect, the generating the first adjustment signal when the first voltage acting on the display screen is detected to be a second value includes: and generating the first adjusting signal every time a time frame is arranged when the first voltage acting on the display screen is detected to be a second value, wherein the time frame is used for indicating the frequency of refreshing a display picture by the display screen. In a possible implementation manner of the first aspect, the adjusting the voltage based on the first adjustment signal such that the first voltage acting on the display screen ranges from the second value to the first value includes: the first voltage is adjusted based on the first adjustment signal every other time frame such that the first voltage acting on the display screen is from the second value to the first value. In the above method, after the electronic device is powered on, the display screen has brightness, and the display screen can refresh the display screen based on the received image data, so that the user can see the display screen with brightness. Because the display screen is periodically (for example, every time frame), when the first voltage is adjusted, the first adjusting signal can be issued according to the same period as the display screen is refreshed, and then the first voltage can be adjusted according to the same period as the display screen is refreshed, and the manner of adjusting the first voltage accords with the existing rule of the display screen and can reduce the use influence on users. In a possible implementation manner of the first aspect, the electronic device further includes a power management chip and a display driving chip, the display screen includes a first power interface, the adjusting the first voltage based
