Abstract: An information display method, an electronic device, and a storage medium are provided. The method includes: obtaining prompt information of a target application; generating, on a virtual screen, a target window corresponding to a window identifier, and taking a screenshot of the target window to obtain a current window screenshot; in a case that a historical window screenshot of the target window exists and that a difference region exists between the current window screenshot and the historical window screenshot, using the difference region as target display information; in a case that no historical window screenshot of the target window exists, using the current window screenshot as target display information; and displaying the target display information in a target region.

Abstract: Disclosed are a household appliance, an apparatus and a method for detecting an arc fault in the household appliance. The apparatus includes: a grid current detecting unit, configured to detect a current from a power grid to the household appliance so as to generate a first current detecting signal; a filter protecting unit, configured to perform an attenuation processing on an arc signal in the power grid; a load current detecting unit, configured to detect an actual running current in a load of the household appliance so as to generate a second current detecting signal; and a control unit connected to the grid current detecting unit and the load current detecting unit respectively, and configured to identify and compare the first current detecting signal and second current detecting signal so as to determine a source of the arc fault.
