The invention relates to a liquid crystal instrument display method and device, and relates to the technical field of instrument display testing, the method comprises the following steps: when a liquid crystal instrument display screen works normally, using the liquid crystal instrument display screen to carry out image display based on image information corresponding to CAN communication information; a preset co-processing unit is used for responding to display abnormal error reporting information or watchdog signal abnormal information corresponding to a liquid crystal instrument display screen, and CAN communication information is received; based on the CAN communication information, the co-processing unit replaces a liquid crystal instrument display screen to receive image information corresponding to the CAN communication information; and the co-processing unit displays corresponding instrument information based on the image information. Various abnormal signals can be monitored, display replacement work and instrument display screen restarting work can be carried out in time on the premise that normal driving is not affected, and driving safety and reliability are effectively guaranteed.

    本申请涉及一种液晶仪表显示方法及装置,涉及仪表显示测试技术领域,该方法包括以下步骤:当液晶仪表显示屏工作正常时,利用液晶仪表显示屏基于CAN通讯信息对应的图像信息,进行图像显示;利用预设的协处理单元响应液晶仪表显示屏对应的显示异常报错信息或看门狗信号异常信息,接收CAN通讯信息;基于CAN通信信息,协处理单元替代液晶仪表显示屏,接收CAN通信信息对应的图像信息;协处理单元基于图像信息,显示对应的仪表信息。本申请能够对多样异常信号进行监测,在不影响正常驾驶的前提下,及时进行显示替换工作以及仪表显示屏重启工作,有效保障驾驶的安全可靠性。
