Control method, device and equipment of power module and storage medium

A power module control method, apparatus and device, and a storage medium are used for reducing display power consumption of a display apparatus. The control method of the power supply module mainly comprises the following steps of: controlling a first gamma current and a second gamma current to reduce a first threshold value within a first preset duration of determining that the display panel enters a blanking stage; the driving process of the display panel comprises a blanking stage and a display stage, and the display panel does not receive data signals in the blanking stage; and controlling the first gamma current and the second gamma current to increase the first threshold value within a second preset duration before the display panel enters the display stage. By the adoption of the design, the gamma current output to the display driving module can be controlled to be decreased in the blanking stage before the display stage, namely the data invalidation stage, and therefore the power consumption of the d
