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 of display screens can be reduced, and the waste of electric quantity is reduced.
本申请公开了一种车辆及其显示屏的驱动方法,涉及车辆技术领域。车辆接收到启动指令后,能够向各个显示屏提供场同步信号,其中提供至任意两个显示屏的场同步信号的相位差大于0。由于流经每个显示屏的电流周期性变化,且该电流在提供至该显示屏的场同步信号由无效电平跳变为有效电平时达到谷值,又由于向任意两个显示屏提供的场同步信号的相位差均大于0,因此可以避免多个显示屏的最大电流同时出现,即可以将多个显示屏的电流的峰值错开,从而可以降低电源与该多个显示屏的供电干路上的压降,减少电量的浪费。
