The invention provides a control device and method for a vehicle-mounted central control display screen. The control device comprises a display screen, a main controller, a power converter, an OR gatecircuit and a first signal control end, wherein the power converter is connected with the display screen and the main controller; the main controller outputs a second enable signal according to an externally input startup and shutdown signal; the first signal control end obtains a first enable signal according to an externally input startup and shutdown signal; the OR gate circuit is respectivelyconnected with the main controller and the first signal control end and is configured to receive a second enable signal sent by the main controller and a first enable signal sent by the first signalcontrol end so as to generate first control signals in different level states; the power converter is connected with the OR gate circuit and configured to receive the first control signal to enable the power converter to supply or disconnect power voltage to the main controller and the display screen. According to the scheme, power-on and power-off control over the whole vehicle-mounted central control display screen is achieved, and the quiescent current is low.

    本发明提供了一种车载中控显示屏的控制装置和方法。该控制装置包括:显示屏、主控制器、分别与显示屏和主控制器连接的电源转换器、或门电路以及第一信号控制端;其中,主控制器根据外部输入的开关机信号输出第二使能信号;第一信号控制端根据外部输入的开关机信号得到第一使能信号;或门电路,分别与主控制器以及第一信号控制端连接,配置为接收主控制器发出的第二使能信号以及第一信号控制端发出的第一使能信号以生成不同电平状态的第一控制信号;电源转换器与或门电路连接,配置为接收第一控制信号使电源转换器向主控制器和显示屏供应或断开电源电压。本发明方案实现整个车载中控显示屏的上下电控制,且静态电流低。
