A method for split-screen display a touch screen display for a terminal and comprising: displaying a first interface in a display region of a screen of the terminal; detecting, in a region at an edge of the terminal, an operation signal in a preset direction, while displaying the first interface; and dividing the display region of the screen into at least two sub-regions according to the detected operation signal, wherein the first interface is displayed in a first sub-region of the at least two sub-regions; wherein the method further comprises: displaying at least one icon of at least one application; and displaying, in a second sub-region of the at least two sub-regions, an interface of a target application of the at least one application, in response to receiving a selection instruction for an icon of the target application; wherein the operation signal comprises two sliding signals applied on two edges of the terminal simultaneously along the preset direction; wherein the terminal has a curved surface screen, and the region at the edge of the terminal refers to two curved-surface side edges of the curved surface screen which are opposite to each other, wherein dividing the display region of the screen into the at least two sub-regions according to the detected operation signal comprises dividing the display region of the curved surface screen into at least two sub-regions, upon detecting simultaneously at each of the two curved-surface side edges a sliding signal in the preset direction. displaying a first interface in a display region of a screen of the terminal; detecting, in a region at an edge of the terminal, an operation signal in a preset direction, while displaying the first interface; and dividing the display region of the screen into at least two sub-regions according to the detected operation signal, wherein the first interface is displayed in a first sub-region of the at least two sub-regions; wherein the method further comprises: displaying at least one icon of at least one application; and displaying, in a second sub-region of the at least two sub-regions, an interface of a target application of the at least one application, in response to receiving a selection instruction for an icon of the target application; wherein the operation signal comprises two sliding signals applied on two edges of the terminal simultaneously along the preset direction; wherein the terminal has a curved surface screen, and the region at the edge of the terminal refers to two curved-surface side edges of the curved surface screen which are opposite to each other, wherein dividing the display region of the screen into the at least two sub-regions according to the detected operation signal comprises dividing the display region of the curved surface screen into at least two sub-regions, upon detecting simultaneously at each of the two curved-surface side edges a sliding signal in the preset direction. displaying at least one icon of at least one application; and displaying, in a second sub-region of the at least two sub-regions, an interface of a target application of the at least one application, in response to receiving a selection instruction for an icon of the target application; wherein the operation signal comprises two sliding signals applied on two edges of the terminal simultaneously along the preset direction; wherein the terminal has a curved surface screen, and the region at the edge of the terminal refers to two curved-surface side edges of the curved surface screen which are opposite to each other, wherein dividing the display region of the screen into the at least two sub-regions according to the detected operation signal comprises dividing the display region of the curved surface screen into at least two sub-regions, upon detecting simultaneously at each of the two curved-surface side edges a sliding signal in the preset direction.
