there are three main situations for the display screen of smart rice cookers.

1. It is powered by battery, that is, whether it is plugged in or not, as long as the battery installed on the panel has power, it will display the time and show the working status at work. In this case, there is generally no switch, so it cannot be turned off. If you don't want to display it, you can only take out the battery.

2. It is powered by battery, and the battery is in it. When the power supply is plugged in, it will automatically charge, and when the power supply is unplugged, it will still be displayed. In this case, the battery cannot be taken out, and there will be no switch, so if the battery is taken out, the panel may be damaged.

3. If there is no battery, it will be on when it is powered on, and it will not be on when it is not powered on. Just unplug the plug from the power supply, and there will be no switch on the display screen.
