That is, in the present application, when the motherboard 20 and the adapter board are simultaneously provided with the power management modules, the first power management module on the motherboard 20 side only needs to provide a power voltage for the adapter board, and the driving voltage required by the display screen 30 is provided by the step-down module 14 and the second power management module in the adapter board according to the power voltage.
Referring to fig. 2, in some embodiments, the adapter board further includes a dial module 15, where the dial module 15 is connected to the motherboard 20 and one of the motherboard 20 side connection interfaces 12, and is configured to receive a reset signal output by the motherboard 20, and output the reset signal to the display screen 30 through the motherboard 20 side connection interface 12 and the screen side connection interface 13.
