Provided are an interface display method and device, a storage medium, and an electronic device. The method includes: a plurality of predetermined functions of a terminal are displayed on a first-level display interface of the terminal; and a first operation performed by a target object is received on the first-level display interface and the terminal is controlled to display a second-level display interface in responsive to the first operation, wherein the second-level display interface is used to respectively display a plurality of different predetermined sub-functions corresponding to the plurality of predetermined functions, the first-level display interface is correspondingly provided with a first interface, the second-level display interface is correspondingly provided with a second interface, the first interface is used to receive a first modification operation performed by the target object so as to modify a display strategy of the first level display interface, and the second interface is used to receive a second modification operation performed by the target object so as to modify a display strategy of the second level display interface. By employing the foregoing technical solution, the problems that the costs for producing a demo version are high and the demo version cannot be flexibly produced during the process of product release in related technology are solved.

A human-machine interaction method for a storage device inside a refrigerator, and a refrigerator are provided. The storage device is arranged in a storage compartment of the refrigerator, and the storage device is provided with an operation panel. An operation surface of the operation panel is provided with a knob module having a display screen, and a touch-sensitive key module. The human-machine interaction method includes: acquiring a startup trigger signal of the operation panel; acquiring an operation instruction received by the knob module and/or the touch-sensitive key module; and making a response to the operation instruction according to a preset interaction solution, and driving the display screen to display a corresponding interface. A user can adjust the functions of the refrigerator through the knob module and the touch-sensitive key module simply and conveniently. The human-machine interaction mode is simple and convenient, and the intelligence of the refrigerator as an intelligent household appliance is significantly improved.
