A method for applying an always-on interface, applied to a terminal with a touch display screen, characterized by, comprising: displaying (501, 1001, 1201) a first always-on interface on the touch display screen, wherein the first always-on interface is an interface displayed when a terminal is in an always-on display state, the always-on display state being a state that the terminal displays basic information in a full black display screen, and the first always-on interface comprises a target control for calling out a target function item in the first always-on interface; receiving (502, 1002, 1202) a first selection operation on the target control; and displaying (503, 1003) an intermediate state interface according to the first selection operation, wherein the intermediate state interface comprises an interaction area of the target function item, and the intermediate state interface is an interface displayed when the terminal is in a half always-on display state, wherein the half always-on display state is a state to which the terminal is switched from the always-on display state in response to the first selection operation on the target control in the always-on display state, and the half always-on display state is used to indicate that the terminal is in a state between the always-on display state and a screen-locked state, the screen-locked state being a state that the terminal has a bright screen and displays a screen-locked interface, and wherein displaying (503, 1003) the intermediate state interface according to the first selection operation comprises: displaying a second always-on interface according to the first selection operation, wherein the second always-on interface is an interface displayed when the terminal is in the always-on display state, and the second always-on interface comprises a preset control for confirming the calling out of the target function item; receiving a second selection operation on the preset control; and displaying the intermediate state interface according to the second selection operation. displaying (501, 1001, 1201) a first always-on interface on the touch display screen, wherein the first always-on interface is an interface displayed when a terminal is in an always-on display state, the always-on display state being a state that the terminal displays basic information in a full black display screen, and the first always-on interface comprises a target control for calling out a target function item in the first always-on interface; receiving (502, 1002, 1202) a first selection operation on the target control; and displaying (503, 1003) an intermediate state interface according to the first selection operation, wherein the intermediate state interface comprises an interaction area of the target function item, and the intermediate state interface is an interface displayed when the terminal is in a half always-on display state, wherein the half always-on display state is a state to which the terminal is switched from the always-on display state in response to the first selection operation on the target control in the always-on display state, and the half always-on display state is used to indicate that the terminal is in a state between the always-on display state and a screen-locked state, the screen-locked state being a state that the terminal has a bright screen and displays a screen-locked interface, and wherein displaying (503, 1003) the intermediate state interface according to the first selection operation comprises: displaying a second always-on interface according to the first selection operation, wherein the second always-on interface is an interface displayed when the terminal is in the always-on display state, and the second always-on interface comprises a preset control for confirming the calling out of the target function item; receiving a second selection operation on the preset control; and displaying the intermediate state interface according to the second selection operation. displaying a second always-on interface according to the first selection operation, wherein the second always-on interface is an interface displayed when the terminal is in the always-on display state, and the second always-on interface comprises a preset control for confirming the calling out of the target function item; receiving a second selection operation on the preset control; and displaying the intermediate state interface according to the second selection operation.
