The invention discloses a circuit adaptive to different vehicle-mounted remote screens and a vehicle-mounted central control display screen. The circuit comprises a host controller, a serializer and a voltage acquisition module, the voltage acquisition module comprises a single-pole double-throw switch; the movable end of the single-pole double-throw switch is connected with an A/D port of the host controller, the first fixed end of the single-pole double-throw switch is connected with the first direct-current power supply, the second fixed end of the single-pole double-throw switch is connected with the display screen circuit, and the host controller collects the voltage of the A/D port; when the moving end is connected with the first fixed end, the host controller takes the acquired voltage as the reference voltage; when the moving end is connected with the second fixed end, the host controller takes the collected voltage as feedback voltage; and the host controller compares the feedback voltage with the reference voltage to judge the resolution of the display screen. According to the method and the device, the display screens with two resolutions can be automatically adapted, and the personalized customization requirements of customers are met.
一种适配不同车载远程屏的电路及车载中控显示屏,包括:主机控制器、串行器和电压采集模块;所述电压采集模块包括单刀双掷开关;所述单刀双掷开关的动端与主机控制器的A/D口相连接,所述单刀双掷开关的第一不动端与第一直流电源相连接,所述单刀双掷开关的第二不动端与显示屏电路相连接,所述主机控制器采集A/D口的电压;当所述动端与第一不动端相连接时,所述主机控制器将采集的电压作为基准电压;当所述动端与第二不动端相连接时,所述主机控制器将采集的电压作为反馈电压;所述主机控制器将反馈电压与基准电压进行比较以判断出显示屏的分辨率。本发明能够实现自动适配两种分辨率的显示屏,满足客户的个性化定制需求。
