The invention discloses an instrument display method and device, an instrument screen and a storage medium, and the method comprises the steps: sending a door opening signal to a host, so as to enable the host to be awakened and read vehicle battery information, and obtaining the remaining electric quantity information; the residual electric quantity information is sent to a serializer, and an LVDS signal is sent to a deserializer through the serializer; decoding the LVDS signal through a deserializer, and converting the LVDS signal into a first IIC signal; sending the first IIC signal to an MCU, and analyzing the first IIC signal through the MCU to obtain a second IIC signal; and sending the second IIC signal to the secondary screen, so that the secondary screen displays the residual electric quantity information according to the received second IIC signal. According to the invention, the wake-up host transmits the residual electric quantity information to the auxiliary screen through the deserializer and the MCU for electric quantity display, so that the problem of charging leakage caused by the fact that the electric quantity cannot be displayed without starting the automobile is solved, and the electric quantity is displayed with low power consumption under the condition of no ignition.
本发明公开了一种仪表显示方法、装置、仪表屏以及存储介质,该方法包括:向主机发送开门信号,以使主机被唤醒并读取车辆电池信息,得到剩余电量信息;将剩余电量信息发送至串行器,通过串行器向解串器发出LVDS信号;通过解串器对LVDS信号进行解码,将LVDS信号转换为第一IIC信号;将第一IIC信号发送至MCU,通过MCU对第一IIC信号进行解析,得到第二IIC信号;将第二IIC信号发送至副屏,以使副屏根据接收的第二IIC信号进行剩余电量信息显示。本发明通过唤醒主机将剩余电量信息通过解串器和MCU传输至副屏进行电量显示,解决了不启动汽车无法显示电量,导致漏充电的问题,不点火的情况下,低功耗的显示电量。
