Abstract

This application provides a touch scanning method, a touch screen, and an electronic device. The method includes: displaying, by an electronic device, a first interface, and performing touch operation scanning on a touch screen in a first scanning manner; and performing, when switching to a second interface, touch operation scanning on the touch screen in a second scanning manner associated with a first area, where a key hot zone in the second interface is located in the first area, and the first area is a position of the key hot zone in the second interface corresponding to the touch screen; and the first scanning manner and the second scanning manner have different scanning directions.

Claims20

Dependent claims

A touch scanning method, applied to an electronic device, wherein the electronic device comprises a touch screen, and the method comprises:

displaying a first interface, and performing touch operation scanning on the touch screen in a first scanning manner;
performing, when switching to a second interface, touch operation scanning on the touch screen in a second scanning manner associated with a first area, wherein a key hot zone in the second interface is located in the first area, and the first area is a position of the key hot zone in the second interface corresponding to the touch screen, and wherein the first scanning manner and the second scanning manner have different scanning directions;
and
when the second interface is switched from portrait display to landscape display, or when the second interface is switched from the landscape display to the portrait display, or when the second interface is switched from display in a first landscape direction to display in a second landscape direction, switching, by the electronic device, to a third scanning manner to perform touch operation scanning based on a second area in which the key hot zone in the second interface is located after the switching the display of the second interface;
and
wherein an angle between the first landscape direction and the second landscape direction is 180°.

3 more elements

A touch screen, configured to:

display a first interface, and perform touch operation scanning on the touch screen in a first scanning manner;
perform, when switching to a second interface, touch operation scanning on the touch screen in a second scanning manner associated with a first area, wherein a key hot zone in the second interface is located in the first area, and the first area is a position of the key hot zone in the second interface corresponding to the touch screen, and the first scanning manner and the second scanning manner have different scanning directions;
and
when the second interface is switched from portrait display to landscape display, or when the second interface is switched from the landscape display to the portrait display, or when the second interface is switched from display in a first landscape direction to display in a second landscape direction, switch to a third scanning manner to perform touch operation scanning based on a second area in which the key hot zone in the second interface is located after the switching the display of the second interface;
and
wherein an angle between the first landscape direction and the second landscape direction is 180°.

3 more elements

An electronic device, comprising a touch screen, a memory, and one or more processors, wherein the touch screen, the memory, and the processor are coupled;

the memory stores computer program code, and the computer program code comprises computer instructions;
and
when the one or more processors execute the computer instructions, the electronic device is enabled to:
display a first interface, and perform touch operation scanning on the touch screen in a first scanning manner;
perform, when switching to a second interface, touch operation scanning on the touch screen in a second scanning manner associated with a first area, wherein a key hot zone in the second interface is located in the first area, and the first area is a position of the key hot zone in the second interface corresponding to the touch screen, and the first scanning manner and the second scanning manner have different scanning directions;
and
when the second interface is switched from portrait display to landscape display, or when the second interface is switched from the landscape display to the portrait display, or when the second interface is switched from display in a first landscape direction to display in a second landscape direction, switch to a third scanning manner to perform touch operation scanning based on a second area in which the key hot zone in the second interface is located after the switching the display of the second interface;
and
wherein an angle between the first landscape direction and the second landscape direction is 180°.
