A method for processing an operation interface and a device for displaying an operation interface are provided. By displaying the operation interface with sector menus in hierarchies, a mapping relationship can be established between a previous level menu and a next level menu, such that a user may choose a corresponding option according to a desired operation in use, and the display layout may be in a way of sectors expanding outwardly. Thus, a more concise display may be achieved, a larger range of parameters may be configured, and more application scenarios can be satisfied.
