Vehicle and driving method of display screen thereof

The invention discloses a vehicle and a driving method of a display screen of the vehicle, and relates to the technical field of vehicles. After the vehicle receives the starting instruction, field synchronization signals can be provided for all the display screens, and the phase difference of the field synchronization signals provided for any two display screens is larger than 0. The current flowing through each display screen periodically changes, the current reaches a valley value when the field synchronization signal provided to the display screen jumps from an invalid level to an effective level, and the phase difference of the field synchronization signals provided to any two display screens is greater than 0, so that the maximum current of a plurality of display screens can be prevented from appearing at the same time; therefore, the peak values of the current of the plurality of display screens can be staggered, so that the voltage drop of the power supply and the power supply trunk of the plurality o
